Step-by-step explanation:

Total amount to spend = 8096.35

Amount already spent = 894. 60 + 1009.99 + 658.50 = 2563.09

Amount left to spend = 5533.26

Answer: 51 feet

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:  

x^2 = a^2 + b^2  

Where x is the hypotenuse of the triangle (in this case length of the rope) and a and b are the other sides.  

The difference between the poles' heights is equal to one side of the triangle (39-15=24), the other side of the triangle is the distance between poles (45).  

Replacing with the values given:  

x^2 = 24^2 + 45^2  

x^2 = 576+2,025

x^2 = 2,601

x = √2,601

x = 51 feet

Answer: Noah scores more than 15 points.

Step-by-step explanation:

Hi, to answer this question we have to analyze the inequality:

15 < n

Where n are the scored points on a basketball game.

< means greater than.

So, in the context of the basketball game, it means that Noah scored more than 15 points.

Feel free to ask for more if needed or if you did not understand something.  

The correct interpretation of 15 < n in the context of the basketball game is that Noah scores more than 15 points.

The inequality 15 < n indicates that the number of points Noah scores, represented by n, is greater than 15. This means that the actual number of points Noah scores must be any number that is a increment above 15, but cannot be 15 itself. For example, if Noah scores 16 points, 17 points, or any number of points greater than 15, the inequality 15 < n would be satisfied. It is a mathematical way of stating that Noah's score exceeds 15 points.

Answer:

Since this is a transversal, I am using certain rules to figure this out.

For example, angles 1 & 2 should equal 180 when added together, in the same way angles 11 & 12 should do the same thing!

Therefore, since angle 1 is 140°, angle 2 should be 40°, to complete it. This is the same for the other side!

Answer:

Angle2: 40

Angle11: 60

Step-by-step explanation:

ang1+ang2=180 (Linear pair)

140+ang2=180

ang2=40

ang2+ang9+ang11=180 (angle sum property)

40+80+ang11=180

ang11=180-120

ang11=60

Answer:

[tex]x=3\\y=6[/tex]

Step-by-step explanation:

[tex]x=y-3\\2x+y=12[/tex]

We have already defined that x = y - 3, replace x for this value.

[tex]2x+y=12\\2(y-3)+y=12[/tex]

Distribute 2.

[tex]2y-6+y=12[/tex]

Add 6.

[tex]2y+y=12+6[/tex]

Combine like terms;

[tex]3y=18[/tex]

Divide by 3.

[tex]y=\frac{18}{3}\\ y=6[/tex]

After having found a variable value, in this case y, replace it in the other equation; x = y - 3, to find x.

[tex]x=y-3\\x=6-3\\x=3[/tex]

Answer:

8

Step-by-step explanation:

This is a right triangle, and we know this because of the little square in the corner. Therefore, we can use the Pythagorean theorem.

a^2+b^2=c^2

a and b are the legs, and c is the hypotenuse.

We know the 6 and the unknown side are the legs, since they form the right angle. We also know that 10 is the hypotenuse, since it is opposite the right angle.

6^2+b^2=10^2

Evaluate the exponents

36+b^2=100

Now, we need to solve for b. To do this, we need to get by itself. First, subtract 36 from both sides

36-36+b^2=100-36

b^2=64

Take the square root of both sides

[tex]\sqrt{b^2}=\sqrt{64}[/tex]

b=8

So, the the unknown side is 8

To find the value of [tex]\(x\)[/tex] in the given circle, we need to use the properties of the circle and the given information about the segments.

1. Given:

PM is a chord of the circle with center [tex]\(Q\)[/tex].

[tex]\(NL\)[/tex] is the perpendicular bisector of [tex]\(PM\)[/tex].

[tex]\(T\)[/tex] is the midpoint of [tex]\(PM\)[/tex], and [tex]\(T\)[/tex] lies on [tex]\(NL\)[/tex].

[tex]\(MT = 5x - 6\)[/tex] and [tex]\(TP = 2x + 9\)[/tex].

2. Key Properties:

Since [tex]\(T\)[/tex] is the midpoint of [tex]\(PM\)[/tex], we have [tex]\(PT = TM\)[/tex].

The perpendicular bisector of a chord passes through the center of the circle, so [tex]\(NL\)[/tex] passes through [tex]\(Q\)[/tex].

3. Equating the Segments:

Since [tex]\(T\)[/tex] is the midpoint of [tex]\(PM\)[/tex], we have:

[tex]\[ PT = TM. \][/tex]

Using the given expressions for [tex]\(MT\)[/tex] and [tex]\(TP\)[/tex]:

[tex]\[ MT = 5x - 6 \quad \text{and} \quad TP = 2x + 9. \][/tex]

Because [tex]\(T\)[/tex] is the midpoint, [tex]\(PT = TM\)[/tex].

Therefore, we have:

[tex]\[ PT = TM = 2x + 9. \][/tex]

Since [tex]\(MT = 5x - 6\)[/tex], and [tex]\(PT = TM\)[/tex], we have:

[tex]\[ 5x - 6 = 2x + 9. \][/tex]

4. Solving for [tex]\(x\)[/tex]:

[tex]\[ 5x - 6 = 2x + 9. \][/tex]

[tex]\[ 3x - 6 = 9. \][/tex]

[tex]\[ 3x = 15. \][/tex]

[tex]\[ x = 5. \][/tex]

Answer: 85 placemats

Step-by-step explanation:

Let’s split it into three parts: how much Samuel can weave, how much Randi can weave, and how much they can weave in total

Part 1: Samuel

First, let’s figure out how much Samuel can weave!

First, we know that Samuel can weave 7 placemats in 8 hours (1 day). So, if he weaved placemats for 5 days, then:

= 7 x 5

= 35

Therefore, Samuel weaved 35 placemats in 5 days if he worked 8 hours each day.

Part 2: Randi

We know that Randi makes 5 placemats in 4 hours, which is half, a day. But lets figure out how many placemats he can make it a day.

All we have to do is multiply by two.

= 5 x 2

= 10

So, we now know that he can make 10 placemats in a day. Now, let’s see how many placemats he can make in five days.

= 10 x 5

= 50

Therefore, Randi weaved 50 placemats in 5 days if he worked 8 hours each day.

Part 3: Adding Them

Now, we have 35 placemats from Samuel and 50 placements from Randi. So, we have to add them.

= 35 + 50

= 85

Therefore, Randi and Samuel can make 85 placemats in 5 days together if they work 8 hours each day.

Samuel and Randi can make a total of 85 placemats in 5 days.

To find out how many placemats Samuel and Randi can make in 5 days, we need to calculate how many placemats each of them can make in one hour. Samuel can weave 7 placemats in 8 hours, so he can weave 7/8 placemats in one hour. Randi can weave 5 placemats in 4 hours, so she can weave 5/4 placemats in one hour. To find out how many placemats they can make in 5 days, we need to multiply their rates by the number of hours they work in 5 days. Samuel can make (7/8) * (8 * 5) = 35 placemats in 5 days. Randi can make (5/4) * (8 * 5) = 50 placemats in 5 days. Therefore, Samuel and Randi can make a total of 35 + 50 = 85 placemats in 5 days.

Answer:

the answer is 2x

Step-by-step explanation:

The greatest common factor of the expression 22x^5 + 20x is 2x. Both the numerical values and the variable components are considered to determine this.

To find the greatest common factor of the expression, we need to identify the highest number and the highest power of variable that evenly divides both terms. In the case of the expression 22x^5 + 20x, the numerical part of the greatest common factor can be found by examining 22 and 20. The greatest common factor of 22 and 20 is 2. Next we need to look at the variables in each term, in this case 'x'. The highest power of 'x' that will divide both 'x^5' and 'x' is 'x' itself.

So, combining these two elements, the greatest common factor of the expression is 2x.
