Step-by-step explanation:
let the width be x
then length is 3x+8
now
we have
p= 2(l+b)
or, 352=2(3x+8+x)
or, 352/2=4x+8
or, 176=4x+8
or, 176-8=4x
or, 168=4x
or, x=168/4
therefore x=42
width =42 yards
length =3x+8=3*42+8=134yards

Y=kx is the direct variation equation
First plug in the x, y values given to find K
18=k(5)
18/5=k
3.6 = k
Use the k and write a new equation.
y=3.6x
Plug in the x value to solve for y.
y = 3.6(11)
y= 39.6
(19+7):(2*6+1)=26:(12+1)=26:13=2
75%
explanation: it can’t be above 100% because that would be over 40.
Answer:
21 feet
Step-by-step explanation:
To solve this question, we would be using the proportion
Shadow /Height
From the question:.
Manny's shadow = 414 feet
Manny's Height = 512 feet
Height of the tree = ? = x
Shadow of the tree = 17 feet
Hence:
414/512 = 17/ x
Cross Multiply
414 × x = 512 × 17
x = 512 × 17/414
x = 21.024154589 feet
x ≈ Approximately = 21 feet
The height of the tree = 21 feet
