A contractor hires 4 workers for a construction project. Each worker is paid $12 per hour. The contractor also buys 20 cubic yards of concrete for the project, at a price of $160 per cubic yard. Which equation best describes the contractor’s total cost, C, if the project takes h hours to complete?
C = (4 x 12)h + (20 x 160)
C = 4(12 + 160)h + 20
C = (20 x 160)h + (4 x 12)
C = 12h + (20 x 160)
Answer:
The answer is C.
Step-by-step explanation:
4 x 12 is how much money per worker per hour. 20 x 160 is how much the cost for the concrete. Adding them gets you the total cost.
Hope this helped!
The equation that can be used to describe the contractor’s total cost, C, if the project takes h hours to complete is C = (4 × 12)h + (20 + 160)
Given:
Number of workers = 4
Earnings of each work = $12
Yards of concrete = 20 cubic yards
Cost per cubic yards = $160
let
C = total cost
h = number of hours needed to complete the project
C = (Number of workers + Earnings of each work)number of hours + (Yards of concrete + Cost per cubic yards)
C = (4 × 12)h + (20 + 160)
Therefore, the equation that can be used to describe the contractor’s total cost, C, if the project takes h hours to complete is C = (4 × 12)h + (20 + 160)

A holiday costs £1900. Work out the
price after a 9% discount.
Answer:
$1729
Step-by-step explanation:
[tex]\frac{100-9}{100} * 1900[/tex]
Answer:
1729
Step-by-step explanation:
1900 divided by 100 is 19
1% equals 19
1 times 9 equals 9
19 times 9 equals 171
171 = 9%

the ratio of 5 more than a number to 20 less than that number is 8:3. What is the number?
Answer:
35
Step-by-step explanation:
Let the number = y ;
5 more than the number = y + 5
20 less than that number = y - 20
Ratio = 8:3;
Solution:
Ratio of the number:
[tex]\frac{y + 5}{ y -20}[/tex] = [tex]\frac{8}{3}[/tex]
Now cross multiply and solve for y;
3(y+5) = 8(y-20)
3y + 15 = 8y - 160
3y - 8y = -160 - 15
-5y = -175
y = 35

the length of a rectangle is 5 more than twice the width. if the perimeter of the rectangle is 76 meters, find the dimensions of the rectangle and choose the equation that represents the perimeter:
1. 76=2w+5
2. 76=2w+2(2w+5)
3. 76=w+2w+5
4. 76=2w+(2w+5)
Answer:
Dimensions: 11 meters by 27 meters
2. [tex]76=2w+2(2w+5)[/tex]
Step-by-step explanation:
Finding Dimensions:
The perimeter of a rectangle can be written as [tex]2l+2w[/tex] where [tex]l[/tex] is the length and [tex]w[/tex] is the width. It is given that the length is 5 more than twice the length of width and the perimeter of the rectangle is 76 meters.
With this information we can write:
Length = [tex]2w+5[/tex]
[tex]2(2w+5)+2w = 76[/tex] (perimeter of the rectangle)
[tex]4w+10+2w=76[/tex]
[tex]6w=66[/tex]
[tex]w=11[/tex]
Length = [tex]2(11)+5[/tex]
Length = [tex]27[/tex]
∴ The dimensions of the rectangle is 11 meters by 27 meters.
Perimeter
Since the length can be written as [tex]2w+5[/tex], the equation that represents the perimeter of the rectangle is [tex]76=2w+2(2w+5)[/tex]

A baseball is hit from an initial height of 3 feet and reaches a maximum height of 403 feet. Which function could be used to model this situation, where h(t) is the height, in feet, after t seconds?
A. h(t) = -16(t - 403)^2 + 3
B. h(t) = -16(t - 5)^2 + 3
C. h(t) = -16(t - 3)^2 + 403
D. h(t) = -16(t - 5)^2 + 403
Answer:
I believe its A
Step-by-step explanation:
D. h(t) = -16(t - 5)² + 403 could be used to model this situation.
What are the given informations ?A baseball is hit from an initial height of 3 feet.
The baseball reaches a maximum height of 403 feet.
Here, h(t) indicates the height in feet after t seconds.
Which function is correct ?At the start, t = 0 & Initial height = 3 feet ,i.e. h(0) = 3
We have to verify options by putting t = 0
A. h(t) = -16(t - 403)² + 3
So, h(0) = -16(0-403)² + 3 = -16(-403)² +3 = -2598544+3 = -2598541
B. h(t) = -16(t - 5)² + 3
So, h(0) = -16(0-5)² + 3 = -16(-5)² + 3 = -400+3 = -397
C. h(t) = -16(t - 3)² + 403
So, h(0) = -16(0-3)² + 403 = -16(-3)² + 403 = -144 + 403 = -259
D. h(t) = -16(t - 5)² + 403
So, h(0) = -16(0-5)² + 403 = -16(-5)² + 403 = -400 + 403 = 3
Hence, in this function h(0) = 3 verified.
Therefore h(t) = -16(t - 5)² + 403 is the required function.

7. The graph of the linear function is shown on the coordinate grid below.
Answer: C . The slope is -4/3 and the y-intercept is 4.
Step-by-step explanation:
Using the two given points, we will use them to evaluate the slope and the y intercept.
(-1.5,6)
( 4.5,-2)
To find the slope we will find the difference in the y coordinates of the points and divide it by the difference in the x coordinates of the point.
6-(-2) = 8
-1.5 - 4.5 = -6
Slope : 8/-6= -4/3.
Since the slope is -4/3, we will use the formula y= mx + b to find the y intercept. In the formula y= mx + b, the slope is m and b is the y intercept.
Use one of the given points, and input its x and y values into the formula including the slope to solve for b(the y-intercept).
We will use the point, ( -1.5,6)
6 = -4/3(-1.5) + b
6 = 2 + b
-2 -2
b = 4.
b is indeed equal to 4 because it even indicates on the graph that the y intercept is 4 which is where x is equal to 0.
