Properties of isosceles triangle:

As per the given statement:

Congruent sides(a) = 3 feet And Vertex angle([tex]\angle QPR[/tex]) = [tex]35^{\circ}[/tex]

Let the length of the base(QR) of an isosceles triangle PQR be 2b.

By isosceles properties, in triangle PQR , the median of an isosceles triangle from its vertex angle is also the perpendicular bisector of the base.

Also, this  line divides the triangle into two congruent right angled triangles whose hypotenuse is 3 feet,

and  [tex]\angle QPS = \frac{\angle QPR}{2} = \frac{35}{2} = 17.5^{\circ}[/tex]

In a right angle triangle QSP

Using sine ratio formula;

[tex]\sin \theta = \frac{\text{opposite side}}{\text{Hypotenuse side}}[/tex]

Hypotenuse sides = PQ = 3 ft and Opposite side = QS = b ft

Solve for b using using sine ratio:

[tex]\sin (17.5^{\circ}) = \frac{b}{3}[/tex]

or

[tex]b = 3 \cdot \sin(17.5^{\circ})[/tex]

[tex]b = 3 \cdot 0.3007057995[/tex]

Simplify:

b = 0.902117398

Length of the base of an isosceles triangle PQR =  2b = 2(0.902117398) = 1.8042348

Therefore, the approximate length of the base of an isosceles triangle is, 1.8 feet

Answer:

 1.80 feet.

Step-by-step explanation:          

Please see the attachment.

Let c be the length of base of our given triangle.

We have been given that an isosceles triangle's congruent sides are 3 feet the vertex angle is 35 degrees. We are asked to find the length of the base of isosceles triangle.      

We will use law of cosine to find the length of our base.

[tex]c=\sqrt{a^2+b^2-2ab\text{ Cos(C)}}[/tex]

Upon substituting our given values in above formula we will get,

[tex]c=\sqrt{3^2+3^2-2\times 3\times 3\times\text{ Cos(35)}}[/tex]

[tex]c=\sqrt{9+9-18\times\text{ Cos(35)}}[/tex]

[tex]c=\sqrt{18-18\times 0.819152044289}[/tex]

[tex]c=\sqrt{18-14.744736797202}[/tex]

[tex]c=\sqrt{3.255263202798}[/tex]

[tex]c=1.8042347970255978\approx 1.80[/tex]

Therefore, the length of base of our given isosceles triangle is approximately 1.80 feet.

Answer:

The point-slope form is y = 3/4x + 10 and the standard form is -3x + 4y = 40

Step-by-step explanation:

In order to find this equation in point-slope form, simply solve for the y value.

y - 4 = 3/4(x + 8)

y - 4 = 3/4x + 6

y = 3/4x + 10

Now to get to the standard form, solve for the constant, then rationalize the denominator.

y = 3/4x + 10

-3/4x + y = 10

-3x + 4y = 40

The equation of the same line in standard form is 3x - y = -9.

The equation of the same line in standard form is 3x - y = -9.

In point-slope form, y - 4 = (3/4)(x + 8). To convert this to standard form, we need to eliminate the fraction by multiplying both sides of the equation by 4. This gives us 4(y - 4) = 3(x + 8).

Simplifying, we have 4y - 16 = 3x + 24. Rearranging the terms, the equation in standard form is 3x - 4y = -40. To make it more standard, we can multiply all the terms by -1 to get -3x + 4y = 40. Finally, we divide all the terms by -1 to get the final equation of the line in standard form: 3x - y = -9.

Step-by-step explanation:

Given trinomial,

[tex]-7x^2-4x+20[/tex]

By middle term splitting,

[tex]=-7x^2-(14-10)x+20[/tex]

[tex]=-7x^2-14x+10x+20[/tex]  

[tex]=-7x(x+2)+10(x+2)[/tex]        

[tex]=(-7x+10)(x+2)[/tex]            

Since, further factorization is not possible,

Thus, the required factorized form of the given trinomial is,

[tex](-7x+10)(x+2)[/tex]    

Option A is correct.

Carmen can buy 4 tubes of paint at $4.80 each after purchasing 2 paint brushes at $6.70 each from her $35 winnings.

Carmen won a prize of $35 in a contest. To answer how many tubes of her favorite paint brand she can buy, first, we need to deduct the cost of the two paint brushes she needs, which are $6.70 each. The total cost for two brushes is:

2 brushes x $6.70 per brush = $13.40

Subtracting this amount from her winnings:

$35.00 - $13.40 = $21.60 remaining

Now, we divide the remaining money by the cost of each tube of paint, which is $4.80, to find out how many tubes she can purchase:

$21.60 / $4.80 per tube = 4.5 tubes

Since Carmen cannot buy half a tube, she can buy 4 tubes of paint and will have some money remaining.

Answer: There are 10 possible ways to get 3 heads. The probability of getting 3 heads from 5 flips would possibly be 10/32, or 5/16. I hope this helped! :)

Final answer:

The number of ways in which 3 heads can occur when 5 coins are flipped is 10. The number of ways in which 3 heads can occur when 6 coins are flipped is 20.

Explanation:

To calculate the number of ways in which 3 heads can occur when 5 coins are flipped, we can use the concept of combinations. The number of ways to choose 3 heads out of 5 coins is given by the formula C(5, 3), which is equal to 10. Therefore, there are 10 ways in which 3 heads can occur when 5 coins are flipped.

To calculate the number of ways in which 3 heads can occur when 6 coins are flipped, we can use the same concept. The number of ways to choose 3 heads out of 6 coins is given by C(6, 3), which is equal to 20. Therefore, there are 20 ways in which 3 heads can occur when 6 coins are flipped.

Answer:

The correct step will be [tex]5(\sqrt{164})=5(\sqrt{4*41})[/tex]

Step-by-step explanation:

We have been given that pond A has a radius of [tex]5\sqrt{(164)}[/tex] meters and radius of Pond B is [tex]\frac{(25\sqrt{200)}}{5}[/tex] meters. Todd simplifies the radius of pond A and we are asked to find out error in Todd's steps.

Step 1: [tex]5(\sqrt{100}+\sqrt{64})[/tex]

Since we know that [tex]\sqrt{ab}=\sqrt{a\times b}=\sqrt{a} \times \sqrt{b}[/tex]. We can see that Todd has made error in his very first step by splitting [tex]\sqrt{164}[/tex] as [tex]\sqrt{100+64}[/tex].

The correct step will be,

[tex]5(\sqrt{164})=5(\sqrt{4*41})[/tex]  

Therefore, the correct step 1 will be: [tex]5(\sqrt{4*41})[/tex].  

Now let us simplify our given radical expression.

[tex]5(\sqrt{4*41})=5(\sqrt{4}*\sqrt{41})[/tex]  

[tex]5\sqrt{4}*\sqrt{41}=5*2*\sqrt{41}[/tex]  

[tex]5*2*\sqrt{41}=10*\sqrt{41}[/tex]  

Therefore, our given radical expression simplifies to [tex]10*\sqrt{41}[/tex] meters.

The incorrect step in Todd's simplification is Step 1, which inaccurately breaks apart the square root of 164.

The step in Todd's simplification of the radius of Pond A that is incorrect is Step 1:

Incorrect Step 1: [tex]5(\sqrt{} 100 + \sqrt{ 64)[/tex]

This is incorrect because it suggests that √164 can be simplifed directly into the sum of the square roots of its components, which is not how square roots work.

The correct step should involve finding the prime factorization of 164 and then simplifying the square root.

Corrected Step 1: [tex]5\sqrt{} (4 x 41)[/tex]

Corrected Step 2: [tex]5(2\sqrt{} 41)[/tex]

Corrected Step 3: [tex]10\sqrt{} 41[/tex]

The fully simplified form of [tex]5\sqrt{} 164[/tex] meters would be [tex]10\sqrt{} 41[/tex] meters.

Answer:

C. $18673.25

Step-by-step explanation:  

Let us find cost of item after 7.7% of sales tax. The price after 7.7% of sales tax will be 17250 plus 7.7% of 17250.

[tex]\text{The cost of item after sales tax}=17250+(\frac{7.7}{100}\times 17250)[/tex]

[tex]\text{The cost of item after sales tax}=17250+(0.077\times 17250)[/tex]

[tex]\text{The cost of item after sales tax}=17250+1328.25[/tex]

[tex]\text{The cost of item after sales tax}=18578.25[/tex]

Therefore, the cost of item after 7.7% of sales tax will be $18578.25.

To find the total cost of item let us add registration fee ($95) to $18578.25

[tex]\text{The total cost of item}=18578.25+95[/tex]  

[tex]\text{The total cost of item}=18673.25[/tex]

Therefore, the total cost of item is $18673.25 and option C is the correct choice.

[tex]p=4h[/tex]    

Step-by-step explanation:

Let p be the number of trees Wangari plants, and h  be the time she spends planting them in hours.

We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.    

Let us find number of trees planted in 1 hour by dividing 12 by 3.

[tex]\text{Number of trees planted in 1 hour}=\frac{12\text{ plants}}{3\text{ hour}}[/tex]

[tex]\text{Number of trees planted in 1 hour}=4\frac{\text{ plants}}{\text{ hour}}[/tex]

We can represent this information as: [tex]p=4h[/tex]

Therefore, the equation [tex]p=4h[/tex] relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.

To estimate 5,271 x 129, we round to the closest thousands and hundreds giving us 5,000 x 100, which equals 500,000. This is an estimation, the actual product of 5,271 and 129 is 679,859.

To estimate the product of 5,271 x 129, we can round each number to the nearest thousands and hundreds respectively. So, 5,271 can be rounded to 5,000 and 129 can be rounded to 100. Our estimation would then be 5,000 x 100 = 500,000.

Remember that this is an estimation. The actual product of 5,271 and 129 is 679,859, but for quick mental calculations or to get a sense of the size of the result, this type of estimation can be helpful.

[tex]R-5=2C[/tex]

Step-by-step explanation:

Let C be the number of apps that Cora have.

We are told that Rita stared the day with R apps. Then she deleted 5 apps. So Rita is left with R-5 apps.

We are also told that after deleting 5 apps Rita still had twice as many apps as Cora has. We can represents this information as:

[tex]R-5=2C[/tex]

Therefore, the equation [tex]R-5=2C[/tex] represents the number of apps each girl has.

Answer:

Rita :R = 2C+5

Cora: C = (R-5)/2

Step-by-step explanation:

Hi, to answer this question we have to write an equation.

Rita has R apps and deletes 5, it means we have to subtract 5 to R. (R-5)

After that she has twice as many apps as Cora has. So, the previous expression is equal to the number of apps that Cora has (C) multiplied by 2.  

The whole equation:  

2C = R-5

For each girl we have to solve for each variable:

Rita's apps:  

2C = R-5

2C+5 =R

R = 2C+5

Cora's apps:

2C = R-5

C = (R-5)/2

Answer:

The price of dinner before sales tax and tip is $60.

Step-by-step explanation:

Let the price of before sales tax and tip be x.

The amount of tip is 20% of the price of dinner. So, the amount of tip is

[tex]\frac{20}{100}x[/tex]

The amount of sales tax is 11% of the price of dinner. So, the amount of sales tax is

[tex]\frac{11}{100}x[/tex]

It is given that Zoe paid $18.60 in sales tax and tips for her dinner. Therefore the sum of tip and sales tax is $18.60.

[tex]\frac{20}{100}x+\frac{11}{100}x=18.60[/tex]

[tex]\frac{20+11}{100}x=18.60[/tex]

[tex]31x=1860[/tex]

[tex]x=60[/tex]

Therefore the price of dinner before sales tax and tip is $60.

Answer:

1.2 litres  more water should Josie drink.

Step-by-step explanation:

As given

It is recommended that an adult drink 64 fluid ounces of water everyday .

As given

1 ounce = 0.0296 litre .

Now convert 64 ounces into litre.

64 ounce = 64 × 0.0296

                = 1.9 litres (Approx)

As

1 litre = 1000 ml

[tex]1\ ml= \frac{1}{1000}\ litre[/tex]

Now convert 700 ml into litre.

[tex]700\ ml= \frac{700}{1000}\ litre[/tex]

[tex]700\ ml= \frac{7}{10}\ litre[/tex]

700 ml = 0 .7 litre

Thus

Recommended amount of water a adult should drink = Amount of water Josie already consumed + More water should Josie drink.

Putting the value

1.9 litres = 0 .7 litres +  More water should Josie drink.

More water should Josie drink = 1.9 - 0.7

More water should Josie drink = 1.2 litres .

Therefore 1.2 litres  more water should Josie drink.

Answer:

The main difference between an observational study and an experiment is the inclusion of a random sample.

Step-by-step explanation:

In an observational study, the researchers do not interfere with the method the data is collected. In an investigation of how regularly the studying improves marks, the researchers sample people from the population who has studied regularly and those who haven't and then collect the average marks obtained by each of the groups. We can only accomplish an association among the response variable and the explanatory variables because there may be some other variable that may affect both the explanatory and the response variable, thus making it look as if there is a relationship among them.

But in an Experiment, the researchers actually interfere with the method the data is collected. In an experiment, each case is randomly assigned to the treatment groups, i.e. to say that each of the cases has an equal chance of being in both groups. These kinds of studies help us to establish causal connections between the response variable and the explanatory variables because random assignment makes sure that they are equally spread among both the groups.

So, the primary difference between an observational study and an experiment is that in case of an observational study there is no random assignment but in case of an experiment there is a random assignment.

Answer: 42°

Step-by-step explanation: In this problem, we're given that the measures of two complementary angles are in the ratio 7 to 8 and we're asked to find the measure of the smaller angle.

Since our two angles are in the ratio 7 to 8, let's represent the angles as 7x and 8x. We will call 7x an angle and 8x its complement. Now, remember that if two angles are complementary, then the sum of their measures is 90 degrees. So we can set up the equation 7x + 8x = 90.

Simplifying on the left side, we have 15x = 90.

Dividing both sides by 15, we find that x = 6.

So the measure of our first angle, 7x, is 7(6) or 42°.

The measure of its complement, 8x, is 8(6) or 48°.

Finally, notice that if we add our two angles together, we have 42 + 48 which equals 90 so our answer checks. This means that the smaller angle is 42°. Image is provided below.

To find the distance between Monica and Gina, the Pythagorean theorem is used because they form a right-angle triangle with Jodie. Calculating the hypotenuse of this triangle with sides of 6 and 7 meters results in a distance of approximately 9.2 meters between Monica and Gina.

The student has asked to find the distance between Monica and Gina, given the positions of three ballet dancers on stage. This problem can be solved using the Pythagorean theorem because Monica, Jodie, and Gina form a right-angle triangle on stage. Monica is behind Jodie and to the left of Gina, meaning that the line segment between Jodie and Monica is one leg of the right triangle, and the line segment between Jodie and Gina is the other leg of the triangle.

To find the distance between Monica and Gina, which is the hypotenuse of the right triangle, we apply the Pythagorean theorem (where d is the distance between Monica and Gina):

Therefore, the distance between Monica and Gina is approximately 9.2 meters.

To find the number of copies above which Company A's charges are higher than Company B's charges, set up an equation and solve for C. The number of copies above which Company A's charges are higher is 6000.

Explanation:

To find the number of copies above which Company A's charges are higher than Company B's charges, we need to set up an equation to represent the total charges for each company. Let C represent the number of copies. For Company A, the total charges can be represented as 360 + 0.12C. For Company B, the total charges can be represented as 720 + 0.06C. We can set these two expressions equal to each other and solve for C to find the number of copies above which Company A's charges are higher.

360 + 0.12C = 720 + 0.06C

0.06C - 0.12C = 720 - 360

-0.06C = 360

C = 360 / -0.06

C ≈ -6000

Since the number of copies cannot be negative, we can conclude that Company A's charges are higher than Company B's charges when the number of copies is greater than 6000.

Yes it is possible for a geometric sequence to not outgrow an arithmetic one, but only if the common ratio r is restricted by this inequality: 0 < r < 1

Consider the arithmetic sequence an = 9 + 2(n-1). We start at 9 and increment (or increase) by 2 each time. This goes on forever to generate the successive terms.

In the geometric sequence an = 4*(0.5)^(n-1), we start at 4 and multiply each term by 0.5, so the next term would be 2, then after that would be 1, etc. This sequence steadily gets closer to 0 but never actually gets there. We can say that this is a strictly decreasing sequence.

If your teacher insists that the geometric sequence must be strictly increasing, then at some point the geometric sequence will overtake the arithmetic one. This is due to the nature that exponential growth functions grow faster compared to linear functions with positive slope.
