Answer:
[tex]D = 63.717[/tex]
Step-by-step explanation:
The details that complete the question are:
[tex](x_1,y_1) = (0,42.78)[/tex]
and
[tex](x_2,y_1)=(90,42.78)[/tex]
Required
Determine how far the ball travelled
Distance is calculated using:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute values for x's and y's
[tex]D = \sqrt{(42.78 - 0)^2+(42.78-90)^2}[/tex]
[tex]D = \sqrt{42.78^2+(-47.22)^2[/tex]
[tex]D = \sqrt{1830.1284+2229.7284[/tex]
[tex]D = \sqrt{4059.8568[/tex]
[tex]D = 63.717[/tex]
Hence, the ball travelled a distance of 63.717 units

Use the distributive property to match equivalent expressions.
-7(4 + x)
-28 + 2x
7(4 + x)
28-7X
7(4-x)
28 +7x
-7(4x)
-28-7x
Intro
Done
Answer:
by distributing you need to multiple by using the 7 in front and use that 7 to multiply each number inside
1. -7(-4+x) -> 28-7x
2. 7(4+x) -> 28+7x
3. 7(-4-x) -> -28-7x
4. -7(4-x)-> -28+7x

Paul won 37 super bouncy balls playing hoops at county fair. At school he gave two to every student in his math class. He only had 3 remaining. How many students are in his class?
Answer:
17 students
Step-by-step explanation:
If he started with 37 and ended with 3 we have to subtract those three first so that we know how many we are actually working with so, 37-3=34. 34 balls is the amount distributed among the class. 34/2 is 17.

Find the percent error in this situation:
Estimated value: 145
Actual value: 189
Answer:
30.3% im so sorry if this is wrong if it is u can report this :(
Step-by-step explanation:
Answer:
23.3%
Step-by-step explanation:
You have to first take the estimated value - the actual value
= 145-189 = -44
Then you want to take -44 divide the actual value which is 189
= -44 / 189= 0.232804233
Lastly, you want to take 0.232804233 and multiply it by 100
= 0.232804233 x 100= 23.28042328
Round that number to get
=23.3%

Olivia wants to know the proportion of students at her school who use a
certain social media app. She interviews a random sample of students at
her school. She finds that 30% of the students in the sample use the app.
What conclusion can she draw from the sample?
А
It is likely that about 30% of the students at her school use the app.
B Exactly 30% of the students at her school use the app.
Every random sample would find that 30% of the students use
the app
It is likely that 30% of the students at her school were selected for
the sample.
Answer:
A
Step-by-step explanation:
Random sampling is a sampling method where each sample has an equal chance of being chosen. The random sample chosen is meant to be an unbiased representation of the population.
If 30% of the sample uses the app, it means that 30% of the population are likely to use the app

Answer:
120 yd
Step-by-step explanation:
To find the volume, we have to multiply the length, width, and height. We have 8, 6, and 10 as our length, width, and height. First, let's go with the length and width. 8 times 6 is 48. Since it's a triangle, we have to divide by 2. 48 divided by 2 is 24. Now let's multiply by the height. 24 times 5 is 120, so that will be your volume.

Triangle ABC is graphed on a coordinate plane with vertices at A(-3, 7), B(9,-8), and C(-5, -6). If triangle ABC is dilated
by a scale factor of 2 with the origin as the center of dilation to create A'B'C', what will be the coordinates of the dilated
vertex of B'?
Answer:
B' = (18, -16)
Step-by-step explanation:
Dilating means to stretch or shrink a figure. The scale factor tells us how much we are stretching or shrinking. The scale factor is 2, so the coordinates are multiplied by 2.
