Answer:
Yes, the difference of two rational numbers is a rational number. The reason for this lies in the following facts: The product of two integers is an integer. The difference between two integers is an integer.
Step-by-step explanation:
7a
TSA = 2lw<span> + 2</span>lh<span> + 2</span><span>wh
TSA = 140 + 70 + 100 = 310 ft^2
7b
310 x $4 =$1240
cost = </span>$1240
7c
V= wlh = <span>7×10×5 = </span><span>350 ft^3</span>
9 will be the answer.....
So we're going to divide those 12-and-a-half by 25 members to find how much each member ate. 12-and-a-half converted into a decimal is 12.50, and 12.50 divided by 25 is 0.5.
Each member had 0.5 of a slice of a pizza, or fraction-wise, each member had half a slice of pizza.
<h3>Given</h3>
a circle with diameter 8 yd
<h3>Find</h3>
the circumference in feet and yards
<h3>Solution</h3>
The circumference of a circle is given by ...
C = πd
where C is the circumference and d is the diameter. For your circle, the circumference is
... C = π(8 yd) = 8π yd ≈ 25.13 yd
There are 3 feet in a yard, so 3 times as many feet.
... C = 24π ft ≈ 75.40 ft
