Answers

Answer 1

Answer:

Step-by-step explanation:

1.  sin37xcsc37

For this use the recipricol identity.  csc37 = 1/sin37

sin37x(1/sin37)  =  (sin37)/(sin37) = 1

2.  sec^2(23) - tan^2(23)

For this one use the pythagorean identity

sec^2(23) = 1+tan^2(23)

1+tan^2(23) - tan^2(23) = 1

when do these 2 lines intersect y = 3x-3, y = 2.3x+4

Answers

Set the equations to equal each other:

3x-3 = 2.3x+ 4

Solve:

Subtract 2.3x from both sides

0.7x -3 = 4

Add 3 to both sides:

0.7x = 7

Divide both sides by 0.7

X =10

Solve for y:

Y = 3(10) -3

Y = 30-3

Y=27

The lines cross at (10,27)

Answer:

(10,27)

Step-by-step explanation:

Plot the first point of the first line by plotting the y-intercept of -3, and using the slope of 3 to plot the rest of the points needed (up 3, over 1).

Plot the first point of the second line by plotting the y-intercept of 4, and using the slope of 2.3 (23/10) to plot the rest of the points needed (up 23, over 10).

After a while of graphing, you will then find that the point of location in which these two lines intersect is (10,27).

A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 245 ounces of a mixture that is 15% salt. How many ounces of water and how many ounces of the 35% salt solution should she use?

Answers

Answer:

140 ounces of water and 105 ounces of 35% salt solution.

Explanation:

Let [tex]x[/tex] be the ounces of water that need to be added and [tex]y[/tex] be the ounces of 35% solution that need to to be added.

We know that the total of ounces of water and of 35% solution must be 245 ounces:

[tex]x+y=245[/tex]

35% of  [tex]x[/tex] is the salt, and since no salt is added with addition of [tex]y[/tex]  liters of water, this must be equal to the amount of salt in the final 15% solution:

[tex]0.35x=0.15*245[/tex]

we solve for  [tex]x[/tex] and get:

[tex]x=105[/tex]

We put this value into [tex]x+y=245[/tex] and solve for [tex]y[/tex] to get:

[tex]y=140[/tex]

Thus we have 140 ounces of water and 105 ounces of 35% solution.

Final answer:

To obtain a 245-ounce mixture at 15% salt concentration, the scientist needs to mix 140 ounces of water with 105 ounces of 35% salt solution by solving a system of equations that involves the total mass of the solution and the mass of the salt in the mixture.

Explanation:

The student is asking for help with a mixing solution problem in algebra where they need to combine water with a 35% salt solution to create a final mixture that has a 15% salt concentration. To solve this problem, two key equations must be set up based on the mixture's total mass and the mass of the salt within the mixture. The student wants 245 ounces of the final mixture.

Let's denote X as the number of ounces of water (0% salt) and Y as the number of ounces of the 35% salt solution. The first equation is based on the total mass of the final solution: X + Y = 245. The second equation is based on the mass of the salt in the solution: 0*X + 0.35*Y = 0.15*245.

Now, we solve the system of equations. The second equation simplifies to 0.35Y = 36.75. Dividing both sides by 0.35 gives Y = 105 ounces. Substituting Y into the first equation gives X = 140 ounces. Therefore, the scientist needs to mix 140 ounces of water with 105 ounces of the 35% salt solution to achieve the desired concentration.

Answers

The value of y-x is (-3)

Solution:

Given: The value of x-y=3

To find: The value of y-x

[tex]\bold{x-y=3\rightarrow (1)}[/tex]

Let's multiply the equation (1) by (- 1) on both sides,

[tex]\Rightarrow\bold{(x - y)\times(- 1) = 3\times(- 1)}[/tex]

[tex]\Rightarrow\bold{-(x-y)=-3}[/tex]

On multiplying the sign,

[tex]\Rightarrow\bold{(-x+y)=-3}[/tex]

The above equation can also be written as,

[tex]\Rightarrow\bold{y-x=-3\rightarrow \text{(The required equation)}}[/tex]

Multiplication of signs:

[tex]\Rightarrow( + )\times( + ) = ( + )[/tex]

[tex]\Rightarrow( + )\times( - ) = ( - )[/tex]

[tex]\Rightarrow( - )\times( + ) = ( - )[/tex]

[tex]\Rightarrow( - )\times( - ) = ( + )[/tex]

In simpler terms, when we multiply two integers with the same signs, the result is always positive and when we multiply two integers with different signs, the result is always negative.

Question:

Suppose you are determining the growth rate of two species of plants. Species A is 25 cm tall and grows 3 cm per month. Species B is 10 cm tall and grows 8 cm per month. Which system of equations models the height of each species H(m) as a function of months m.

Answer:

The system of equations that models the height of each species H(m) as a function of months m is: [tex]H_A(m) = 25 + 3m \text{ and } H_B(m) = 10+8m[/tex]

Solution:

[tex]H_A(m)[/tex] = the height of species A as a function of months m

[tex]H_B(m)[/tex] = the height of species B as a function of months m

Species A is 25 cm tall and grows 3 cm per month

Let "m" be the number of months

Therefore, a equation is framed as:

Species A : 25 cm + 3(number of months)

[tex]H_A(m) = 25 + 3m[/tex]

Species B is 10 cm tall and grows 8 cm per month

Therefore, a equation is framed as:

Species B : 10 cm + 8(number of months)

[tex]H_B(m) = 10+8m[/tex]

Thus the system of equations that models the height of each species H(m) as a function of months m is: [tex]H_A(m) = 25 + 3m \text{ and } H_B(m) = 10+8m[/tex]

Answers

Hiya

Make sure you know the Order of Operations, or PEMDAS.

PEMDAS:

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

When simplifying, you need to do it in this order. However, with multiplication and division, you do it whichever comes first. If it's 24 times 3 divided by 4, you do multiplication first because it came first in the problem. Then you divide by 4.

The same thing with addition and subtraction. For example, 2 + 4 + 8 - 11, you need to add 2+4+8 first because addition came first before subtraction.

If you don't understand feel free to reply with questions about it.

ALSO: If numbers are written together like (-2)(3), this means they are being multiplied.

Okay so let's solve this equation now.

Looking at PEMDAS, the first step would be to multiply or divide. Seeing that division comes first, do 24 divided by -2.

24 ÷ -2 = -12 (Remember that positive divided by a negative or the other way around will always result in a negative. Same with multiplying)

Now we have: -12(3)+7

Next step is multiplication so -12*3=-36

Now we have -36 + 7.

Adding a negative is the same as subtracting a positive so you can re-write this as 7- 36. Well, 36 - 7 is 29, so 7 - 36 = -29.

So, the answer is -29

A truck enters a highway driving 60 miles per hour a car enters the highway at the same place 9 minutes later and drive 68 miles per hour in the same direction from the time the car enters the highway how long will it take the car to pass the truck

Answers

The time taken by car to pass the truck is 1.125 hours

Solution:

A truck enters a highway driving 60 miles per hour a car

The car enters the highway at the same place 9 minutes later and drive 68 miles per hour in the same direction from the time the car enters the highway

Let us first convert 9 minutes to hours

[tex]1 \text{ minute } = \frac{1}{60} \text{ hour }[/tex]

[tex]9 \text{ minute } = \frac{9}{60} = \frac{3}{20} \text{ hours }[/tex]

Let the truck covers 'x' m distance in time 't' hour the car will take [t -(3/20)] hour to cover the same distance 'x'

We know that,

[tex]Distance = Speed \times Time[/tex]

For truck : [tex]x = 60t[/tex] ----------- eqn 1

For car: [tex]x = 68 \times (t - \frac{3}{20})[/tex] ------------ eqn 2

From equations (i) and (ii)

[tex]60t = 68 \times(t-\frac{3}{20})\\\\60t = 68t-10.2\\\\68t - 60t = 10.2\\\\8t = 10.2\\\\t = 1.275[/tex]

Thus the time taken by car to pass the truck is:[tex]t - \frac{3}{20} = 1.275 - \frac{3}{20} = 1.275 - 0.15 = 1.125[/tex]

Thus the time taken by car to pass the truck is 1.125 hours

Solve the equation.

9) In one year, Angie's height went from 58 to 60 inches. What was the percentage increase in Angie's height? (Round to the nearest percentage)

Answers

The percentage increase in Angie's height is 3 %

Solution:

Given that, In one year, Angie's height went from 58 to 60 inches

To find: percentage increase

The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.

The percent increase is given as:

[tex]\text { percent increase }=\frac{\text { final value - initial value}}{\text { initial value }} \times 100[/tex]

Here in this problem,

Initial value = 58 inches

Final value = 60 inches

Substituting the values we get,

[tex]percent\ Increase = \frac{60-58}{58} \times 100\\\\percent\ Increase = \frac{2}{58} \times 100\\\\percent\ Increase = 0.0344 \times 100\\\\percent\ Increase = 3.45 \approx 3[/tex]

Thus percentage increase in Angie's height is 3 %

The velocity v of an object rolled down an inclined plane is given by the formula v=
53d, where d is the distance the object has rolled, Solve the formula for d.

Answers

Final answer:

To find the distance an object has rolled down an inclined plane from the velocity equation v = √(53d), square both sides of the equation and then divide by 53 to solve for d.

Explanation:

The velocity v of an object rolled down an inclined plane is given by the formula v = √(53d), where d is the distance the object has rolled. To solve this equation for d, we can square both sides of the equation to remove the square root. The steps are as follows:

Square both sides of the equation: v² = (53d)².

Divide both sides by 53 to isolate d: d = v² / 53.

Now, d represents the distance the object has rolled down the inclined plane as a function of its velocity v.

Austin correctly answered 92% of the questions on the geography quiz. Liz and third 47 of the 50 questions correctly who earned a higher score? Explain.

Answers

Liz scores a 47/50 = 94/100 = 94%
92%<94%
Liz earned a higher score

Final Answer:

Liz's score is higher than Austin's

Explanation:

To solve this problem, first we need to calculate the percentage of correct answers that Liz got. We know that Liz answered 47 questions correctly out of a total of 50 questions. To calculate the percentage, we'll divide the number of questions Liz answered correctly by the total amount of questions and then multiply by 100.

This gives us the percentage of correct answers that Liz got.

We then compare it to the percentage that Austin got, which is 92%.

Doing so, we find that Liz's score is higher than Austin's. Hence, Liz earned a higher score.
