Answer:
D
Step-by-step explanation:
We have the expression
First we need to distribute the negative throughout the parenthesis. Then we can combine like terms in order to simplify this expression
This answer matches D.

Answer:
- 127.32 yards diameter
- 12,732.4 square yards area
Step-by-step explanation:
The diameter can be found from the circumference using the relation ...
C = πd
d = C/π = (400 yd)/π ≈ 127.32 yd . . . . diameter
The area is ...
A = πr²
where the radius (r) is half the diameter.
A = π(63.662 yd)² ≈ 12,732.4 yd² . . . . area
_____
<em>Additional comment</em>
We have used a full-precision value for pi. If you use 3.14, your answers will be different. Your diameter will be about 127.4 yards; your area about 12,738.9 yd².
To solve, set up a proportion
3.25 cups x cups
---------------- = ---------------
13 servings 28 servings
Now cross multiply
13x = 28 * 3.25
Simplify.
13x = 91
Divide both sides by 13
x = 7 cups
To check your answer, use proportions again, but change the left side to 4.5 cups over 18 servings, use the same steps, if the answer is the same as above, then the answer is correct
Answer:
$179.99
Step-by-step explanation:
Take total cost and multiply by the percent in decimal form
$199.99*0.10
=$19.99
Subtract the 10% from the original sum
$199.99-$19.99
=$179.99
