Answer:
200 miles
Explaination:
in order to fiind the point of interaction you must put the world problem into an liner equation.
y=mx+b
key:
miles : x
y= 0.70x + 120
&
y= 0.90x + 80
now you put them together
0.70x + 120 = 0.90x + 80
-0.70x. -0.70x
____________________ subtract slope from both sides
120 = 0.20x + 80. ( doesn't matter which one)
-80 - 80
____________________ subtract
40 = 0.20x
_________ Divide each # with the slope
0.20 0.20
200 = x
hope this helps!
If xx and y vary directly and y is 21 when x is 7, find y when x is 5
Answer:
y = 15
Step-by-step explanation:
We need to solve for k
y = x
21 = 7k Divide both sides by 7 to solve for k
3 = k
y = xk
y = 5(3)
y = 15
Answer: y = 15

Find the perimeter of this shape.
Answer:
draw a line that makes a triangle and rectangle.
hypotenuse= 30
3k-4k-5k triangle
18-24-30
so the short part of triangle is 18 cm
10+10+18+24+30 equals 92
sorry for language I am not familiar with English
the perimeter of this shape is
24+10+10+30+\(\sqrt{30^{2} -24^{2} }\) = 92 cm
please help me i will give brainliest to first person to anwser.
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

What is the scale factor of this dilation?
A.) One-half
B.) Two-thirds
C.) Three-fourths
D.) Three-halves
Answer: C) Three-fourths
I.e., the fraction 3/4
======================================================
Explanation:
Let's pick on the horizontal sides. Divide the image length Y'Z' = 9 over the corresponding preimage length YZ = 12 to get
(Y'Z')/(YZ) = 9/12 = 3/4 which is the scale factor
The scale factor is less than 1, meaning the image's lengths are shorter compared to the preimage's corresponding lengths.
-----------------
Alternative Paths:
You can pick any other pair of corresponding sides to get the same result:
(X'Y')/(XY) = (7.5)/(10) = 75/100 = 3/4(Z'X')/(ZX) = 6/8 = 3/4Answer:
\(scale ~factor= Z'Y'/ZY\)
\(=9/12\)
\(=3/4=0.75\)
\(So ~your~ answer ~will~ be ,~C.) Three-fourths\)
-------------------------------

The surface area of a rectangular prisim is 226in square, what would be the surface area if it is scaled up by a factor of 10?
Answer:
2260 in^2
Step-by-step explanation:
scaled basically means multiplied by
so 226 times 10 is 2260

Answer:
721.1 in/60.1 ft
Step-by-step explanation:
Assuming that the ball travels in a straight line from the release point to the corner pin, we can use the Pythagorean theorem to find the length of the bowling lane.
Let x be the length of the bowling lane in inches. Then we have:
x^2 = 40^2 + 720^2
x^2 = 1600 + 518400
x^2 = 520000
x = sqrt(520000)
x ≈ 721.1 inches
Rounding to the nearest tenth, the length of the bowling lane is approximately 721.1/12 = 60.1 feet.
Therefore, the length of the bowling lane is approximately 60.1 feet.
Answer:
The length of the bowling lane is 718.9 in
Hope this helps!
Step-by-step explanation:
The question is probably asking for the height of the triangle ( b ) so a is 40 in and c is 720 in : * use formula; c² - a² = b² *
720² - 40² = b²
518400 - 1600 = b²
516800 = b²
b = \(\sqrt{516800}\)
b = 718.888030... in
( c is the hypotenuse and the length for that is already given, it's 720 in )

Identify which equations have one solution, infinitely many solutions, or no solution.
3/2x + 2.3 – 1/2x = 4.3 + x
2x + 2/3 = 2x + 4/5 – 4x
17/4 + 4.2y - 9/4 = 2.2y + 6 + 2y - 4
5r + 2 = 6r + 3 – r
-2x + 2 + 4x = 16/5 + 2x - 6/5
3.2p – 2.5 + 2.1p = 5p – 7/2
