Please help with this question!!
The distance, d, that a certain car is from Math City after h hours, can be determined by the equation d=45h. The distance that a second car is from Math City can be determined by the equation d=25h+80. After how many hours will the two cars be the same distance from the Math City?
Answers
Answer:
4 hours
Step-by-step explanation:
First car distance
d = 45h
Second car distance
d = 25h + 80
After how many hours will the two cars be the same distance from the Math City?
Equate both car's distances
45h = 25h + 80
Collect like terms
45h - 25h = 80
20h = 80
Divide both sides by 20
h = 80 / 20
= 4
h = 4 hours
The two cars will be at the same distance from the Math City in 4 hours

A home improvement store advertises 60 square feet of flooring for $287.00. The price includes an $80.00 installation fee. How much does each square feet of flooring cost, including the installation fee? Your answer, in dollars and cents, should be a decimal rounded to the nearest hundredth (penny).
Answers
Answer:
$4 78 cents
Step-by-step explanation:
If home improvement store advertises 60 square feet of flooring for $287.00 ($80 installation fee inclusive), to get the price per square feet of the flooring cost, we will use the expression;
60 sq.ft = $287
1 sq. ft = $x
Cross multiply
60x = 287
Divide both sides by 60
60x/60 = 287/60
x = 4.783
x ≈ 4.78 (to the nearest hundredth)
Hence the price per square feet of the flooring is $4.78 or $4 78 cents
Note that $80 was not added to $287 because we are told that this price ($287) already includes the installation fee.

Answers
Answer:
Hi there!
Your answer is:
A: -56
Step-by-step explanation:
-14=1/4 X
Solve for x!
Multiply both sides by the inverse of 1/4, which is 4! (1/4*4=1)
-14=1/4x
*4 *4
-56 = 1x
ALSO! Check your work!
-14= 1/4(-56) ??????
-14 = -14 YES
Your answer is A: -56
-14=1/4 X
Multiply both sides with the inverse of one over four (1/4*4=1)
-14=1/4x
*4 *4
-56 = 1x
Jeremy stands on the edge of a river and throws a rock into the water. The rock leaves his hand at a height 4 feet above the water. The rock reaches the highest point along its path when it is a horizontal distance of 28 feet from his hand and 17 feet above the water. Write a function to represent the height of the rock in terms of its distance from Jeremy’s hand.
Answers
Answer:
The height, h, of the rock as a function of the horizontal distance from Jeremy's hand is h = -13/784·(x - 28)² + 17
Step-by-step explanation:
The given parameters are;
The height of the rock above the water when it leaves Jeremy's hand = feet
The maximum height of the rock = 28 feet
The horizontal distance at maximum height = 17 feet
Therefore, the given coordinates of the maximum height = (28, 17)
The equation of a parabola in vertex form is f(x) = a(x - h)² + k
Taking the maximum point as the vertex of the parabola, we have;
(h, k) = (28, 17)
Substituting the values gives;
f(x) = a·(x - 28)² + 17
At x = 0, the height = 4, we have;
f(0) = 4 = a·(0 - 28)² + 17
4 - 17 = a×28²
-13 = 784 × a
a = -13/784
Therefore, the height of the rock, f(x) = h, as a function of the horizontal distance from Jeremy's hand is therefore;
f(x) = h = -13/784·(x - 28)² + 17

A turtle travels one half of a foot in 4 seconds. How many feet will a turtle travel in 7 seconds?
Answers
Answer: 10.5 inches or .875 feet.
Step-by-step explanation:
First calculate the SPEED = Distance /Time. So 1/2 of a foot = 6 inches so distance of 6 inches divided by time of 4 sec = s 1.5 (inches) per sec. So using Distance = speed x time we calculate 1.5in x 7 sec= a distance of 10.5 inches or 10.5 inches divided by 12in that is in a foot = .875 feet.

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression, 2.75+0.10x, where x is the number of years since 1980. Which part of the expression corresponds to the cost of movie tickets in 1980?
Answers
Answer:
$4.7Step-by-step explanation:
step one:
Let the cost be y
to solve for the cost of a movie ticket, we need to solve the expression
y=2.75+0.10x
step two:
given that x is the number of years between 1980-2000
the number of years is 20years
put x= 20 in the expression for the cost we have
y=2.75+0.10(20)
y=2.7+2
y=$4.7
