Given
piece of plywood measuring 2 feet 8 inches long by 2 feet 4 inches wide.
What is the area of a piece of plywood .
To proof
Here plywood shape in the form of rectangle.
Formula
Area of rectangle = Length×Breadth
As given in the question
Length =2 feet 8 inches
Breadth = 2 feet 4 inches
First convert feet into inches
1 feet = 12 inches
2 feet 8 inches = 2×12 + 8
= 32 inches
Also
2 feet 4 inches = 2×12 +4
= 28 inches
put is in the above formula
Area of plywood = 32 ×28
= 896 inches²
Therefore option (b) is correct
Hence proved
Answer:

it's a whole number
Answer:
.
Step-by-step explanation:
We need to write an equation for the amount of chemical B as a function of the amount of chemical A.
...(1)
where, k is constant of proportionality.
It is given that fifteen grams of chemical A is used to produce 3 grams of chemical B. It means a=15 and b=3.
Substitute a=15 and b=3 in (1).
Substitute 
in (1).
Therefore, the required function is .
Answer:
A = 3.14 × r²
Step-by-step explanation:
A = πr²
A = 3.14 × r²
If 55% of the student body are boys, then 45% are girls.
35% of boys are on the honor roll, so 35% of 55% are on the honor roll.
40% of girls are on the honor roll, so 40% of 45% are on the honor roll.
So now we need to find each of those numbers...
35% of 55% =
.35 * .55 = .1925 multiply by 100 to convert to percent
19.25% of boys (in the student body) are on honor roll
40% of 45% =
.40 * .45 = .18 multiply by 100 to convert to percentage
18% of girls (in the student body) are on honor roll
Add the two together to get the total percentage of student body that is on the honor roll...
19.25% + 18% = 37.25%
Round to the nearest percent
37%
