A truck can be rented from Company A for $120 a day plus $0.70 per mile. Company B charges $80 a day plus $0.90 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answers
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!

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 )

1.25 x 2 = 2.50
4.15 + 3.50 = 7.65
7.65 + 2.50 = 10.15

C.) Three-fourths
D.) Three-halves
Answers
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:
\(scale ~factor= Z'Y'/ZY\)
\(=9/12\)
\(=3/4=0.75\)
\(So ~your~ answer ~will~ be ,~C.) Three-fourths\)

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
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.
