Answer:
y = −1/3x + 10/3
Step-by-step explanation:
The ratio of width to height is 5 to 8. Using this ratio, you can determine the lengths.
1. 5/8=10/x
5x=80
x=16in
2. 5/8=15/x
5x=120
x=24in
3. 5/8 = 8/x
5x=64
x=12.8in
Answer:
$2.77 per bar sold
Step-by-step explanation:
Hi there!
We're given that selling 9 ice cream bars could make the truck driver $24.93. To find how much he'd make per bar sold, divide $24.93 by 9 ice cream bars:
24.93 ÷ 9 = 2.77
Therefore, the truck driver would make $2.77 per bar sold.
We could also find this answer using the given equation, y=kx.
y=kx
Let y equal the earnings. Let x equal the number of ice cream bars sold. Let k equal how much the driver would make per bar sold.
24.93=k(9)
24.93=9k
x=2.77
I hope this helps!
The range of values of a random variable
Here we would use the idea that the post and its shadow form a triangle and the tree and its shadow form a triangle and the side lengths of these two triangles are of the same ratio, ie. if the height of the tree is given by h then:
5/8 = h/48
h = 48*(5/8)
h = 6*5 = 30
Thus the tree is 30 ft tall
