Answer: square root of 89 units i think so

Step-by-step explanation:

The distance between the points (−2, −4) and (−7, −12) is √89 units.

Among the given options, the correct answer is "square root of 89 units."

To determine the distance between the points (−2, −4) and (−7, −12), we can use the distance formula. The distance formula calculates the distance between two points (x₁, y₁) and (x₂, y₂) in a Cartesian coordinate system.

The distance formula is given by:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Let's substitute the coordinates of the given points into the formula:

d = √((-7 - (-2))² + (-12 - (-4))²)

= √((-7 + 2)² + (-12 + 4)²)

= √((-5)² + (-8)²)

= √(25 + 64)

= √89

Answer:

B

Step-by-step explanation:

You pay $117 no matter how many kids show up and then you pay an additional fee of 6.50 per kid.

1 kid

y = 6.50(1) + 117

y = 123.50

If 10 kids come

y = 6.50(10) + 117

y = 65 + 117

y = 182

You can use this equation to help you figure out how much it will cost you depending on how many kids you invite.

Answer:

n=9

Step-by-step explanation:

Answer:

-9, 1/5, 12/20

Step-by-step explanation:

-9 is negative so it will always be the least. It helps to turn the fractions into decimals. To do this, you can just divide 1 by 5 and 12 by 20.

1/5 = .2

12/20 = .6

So, 1/5 is less than 12/20.

This makes the order -9, 1/5, 12/20.

Answer:

-9, 1/5 12/20

Step-by-step explanation:

Use 0 as a border.

All numbers less than 0 on one side the rest on the other.

You will have -9 on less than zero and 1/5, 12/20 on the other side.

So -9 is the least.

Now you have 1/5, and 12/20.

Make the denominators equal.

1/5 x 4/4= 4/20, 12/20 x 1/1 = 12/20

Compare the Numerators.

4 is less than 12.

So the answer is -9, 1/5, 12/20.

1. It is a built different (lol) triangle. So, you want to multiply 8.3x4.1 to get 34.03 and divide that by 2 (A=L*W/2) to get 17.015in.

2. Another triangle, so multiply 13*9 to get 117 and divide that by 2 to get 58.5 yds.

3. This is not a triangle so just A=L*W*H. So, multiply 14.8*17.3*8.1 to get 2073.92 yds.

4. This is a triangle and we need to find the height of the triangle. So, we need to divide 26.27 by 3.7 to get 7.1 as the height.

Answer:

To find the scalar value, simply choose one side of D and one did of D’ and divide them to find the scalar. We can verify that we have the correct scalar by performing this division on each related edge. Below I will do D to D’ represented like D/D’:

4.8 / 1.2 = 4

5.2 / 1.3 = 4

3.6 / x = 4

Knowing that the scaling for each edge is 4, we can solve for x.

3.6 / 3 = x

1.2=x

So we know the edges for D are 4.8, 5.2, and 3.6 respectively to D’ scaled by 1/4. So we can determine that the edges for D’ are 1.2, 1.3, and 1.2 respectively to D scaled by 4.

So if we go D’ to D, we scale by 4. If we go D to D’, we scale by 1/4.

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer:

Hello your answer should be OPTION C.

Step-by-step explanation:

The volume of a cube can be calculated with the following formula:

Where "s" is the length of each edge of the cube.

Solving for "s":

8 = 3√v

Let's check each option to find which volume would work according to the size she needs:

A. Substitute V  216 in.³ into 8 = 3√v then: 8 = 3√216 in.³ = 6 in    

B.Substitute   V =  125 in.³ into 8 = 3√v then: 8 = 3√ 125 in.³ = 5 in

C. Substitute   V =  64 in.³ into 8 = 3√v then: 8 = 3√ 64 in.³ = 4 in.

Based on these results, we can determine that the cubes with a volume of 64 in.³ would work.

Answer:

60

Step-by-step explanation:

these are alternate angles between two parallel lines.

which means that 120=2x

so u can calculate the value of x through this equation.

120=2x

120/2=x=60

Answer:

x = -1

y = 3

Step-by-step explanation:

Add the two equations together.

You get:

4x = -4

You may notice that there is no y, and that is because the y's cancel out. -y + y = 0, so there's no use in putting y in.

x = -1.

Plugging x in, we get:

-1 - 2y = -7.

Move the -7 over to the left side.

6 = 2y

Therefore, y = 3.

We can check our answer by plugging the values in.

3(-1) + 2(3) is supposed to equal 3.

-3 + 6 = 3, and so we know our answer is correct.

Answer:

x = -1

y = 3
