The distance between -10 and 5 on a number line is 15

From the question, we are to determine the distance between the given points on a number line

The given points are -10 and 5

On a number line, the distance between any two points is the difference between the largest number and the smallest number

That is,

Distance between two points on a number line = Value of the largest number - Value of the smallest number

The given points are -10 and 5

The largest number is 5

and

The smallest number is -10

Thus,

Distance between -10 and 5 on a number line = 5 - -10

Distance between -10 and 5 on a number line = 5 + 10

Distance between -10 and 5 on a number line = 15

Hence, the distance between -10 and 5 on a number line is 15

This means that Kenna will get 18 pieces from one lenght of pipe

The dimensions of the concrete patio should be 23ft x 12ft x 0.5feet.

Since a rectangle is two-dimensional, while a cube is three-dimensional, the dimensions of the concrete patio include its length, width, and height or thickness.

The quantity of concrete required = 138ft³

The perimeter of the patio = 70 feet

Height = 6 inches or 1/2 foot or 0.5 ft

Perimeter = 2(L + W)

70 = 2(L + W)

L + W = 35 (70/2)

The possibilities for the length and width include 20 and 15, 25 and 10, and lastly, 23 and 12, which are also the two pair factors of 276.

Let L = 23 (the length is always longer than the width)

W = 12 (35 - 23)

Check:

Volume of concrete = 138ft³

Area = 276ft² (138ft³/0.5ft)

Two pair factors of 276 are 92 and 3, 46 and 6, 23 and 12, 2 and 138, and 1 and 276.

Given also that (23 + 12)2 = 70 (perimeter)

The dimensions that meet the two requirements are:

Length = 23 feet

Width = 12 feet

and Height = 0.5 feet

= 23 x 12 x 0.5 = 138

Thus, the dimensions of the concrete patio should be 23ft x 12ft x 0.5feet.

Answer:

Step-by-step explanation:

1) Distribute the numbers outside of the parenthesis to the numbers inside the parenthesis. This means multiple the outside number to all the numbers that are inside the parenthesis:
-5+25k-8k-20

2) Combine the like terms. The number with k get combined together since they both have a k. The numbers without a k get combined together. When you combine, you ADD the numbers together.

-13k+5

Length of the yard = 24.75 feet

Width of the yard = 12.75 feet

Perimeter of the yard = 75 feet (24.75 + 12.75)2

Charges for a yard of iron fencing = $50 per yard

3 feet = 1 yard

75 feet = 25 yards (75/3)

The cost of 25 yards = $1,250

A linear pair is formed of ∠1 and ∠2. The measures of the angle ∠1 is 20 and ∠2 is 160.

Given that,

A linear pair is formed of ∠1 and ∠2.

We have to find the measurements of both angles if m∠1 is eight more than m∠2.

When they refer to something as "linear," they mean that two angles create a straight line (or, 180 degrees). In other words, the two angles add up to 180.

Let us take the ∠1 as x

Then ∠2 will be 8x.

Now, we can write as

x+8x=180

9x=180

x=180/9

x=20

Therefore, the measures of the angle ∠1 is 20 and ∠2 is 8×20=160.

Answer: the ratio is 1.13

Step-by-step explanation:

The ratio of non-black sedans to black sedans is 40/31, as of the given condition.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,

The total number of sedans in the parking lot is,
496 black sedans + 640 non-black sedans = 1136 sedans.

The ratio of non-black sedans to black sedans can be found by dividing the number of non-black sedans by the number of black sedans:

Ratio = 640 non-black sedans / 496 black sedans
Ratio  = 640/496
Ratio = 40/31

So, the ratio of non-black sedans to black sedans is 40/31.

The number of students from country C using mathematical operations is 113,115.

The mathematical operations are addition, subtraction, multiplication, and division.

These mathematical operations are used to determine the output value, given some input values.

The number of foreign students from country B = 138,000

Students from country B are 22% more than the number of students from country C.

Assume that the number of students from country C = 100%

Then the number of students from country B = 122% (100 + 22)

If the number of foreign students from country B is 138,000, which is 22% more, then the number of students from country C is as follows:

The number of students from country C = 113,115 (138,000/1.22)

The corresponding angles of both triangles are not congruent to each other, therefore: B. ΔRST is not similar to ΔUVW.

If two triangles are similar to each other, their corresponding interior angles measures would be congruent to each other, while their corresponding side lengths would be proportional to each other.

Angle R = 55°

Angle T = 45°

Angle S = 180 - 55 - 45 = 80°.

Angle U = 55°

Angle V = 75°
