The total area is 200 ft^2.
Answer:
21 and 14
Step-by-step explanation:
The relationship between x and y is proportional thus the equation is
y = kx ← k is the constant of proportion
To find k use the ordered pair y = 84 when x = 28 , then
84 = 28k ( divide both sides by 28 )
k = 3
y = 3x ← equation of proportion
When x = 7 , then
y = 3 × 7 = 21 ← value required in top table
When y = 42 , then
42 = 3x ( divide both sides by 3 )
x = 14 ← value required in lower table
Answer:

Step-by-step explanation:
If the third multiple of the whole number is
. This means that
is completely divisible by the number
.

So, the whole number is
.
The fifth multiple would mean the product of
and 

The fifth multiple of the whole number is
.
Since a right angle is 90 degrees you can classify other angles by seeing if they are less or greater than a 90 degree angle.If it's less than 90 degrees its an acute angle.If it is greater than 90 than its obtuse but its less than 180.180 is a straight angle
