Answer:
37.5% decrease
Step-by-step explanation:
By using this formula: (New - Old) ÷ New
(20000 - 32000) ÷ 32000 = -12000/32000
-12000/32000 x 100 = -37.5% (Negative means decrease)
This is quite easy as it is simply knowing the formulas to solve different portions of the circle.
(A) To solve for circumference, the formula is d*pi where d is the diameter. The diameter is simply twice the radius, so we can just double 11 for it. This means 22 is the answer.
(B) The formula for area of a circle is pi*r^2, so for this one, we just need to square the radius. 11 squared is 121.
(C) To solve this, we should solve for the area of the circle, and then multiply it by 3 to represent the 3 dollars. To solve the area, we just substitute 11 into the formula for r. Afterwards, we should multiply it by 3 for the reason above. However, because we used 3.14 instead of pi, we must say the cost is approximately $1139.82. <span />
Answer:
False.
Step-by-step explanation:
The answer is NOT 6 1/2 loaves it is 6 loaves.
Knowing that there Max has 5 1/4 cups of raisins and each loaf requires 7/8 cup of raisins, we would need to divide.
Let's turn the 5 1/4 into an improper fraction so when we divide the two fractions, it would be easier!
<u>To turn 5 1/4 into an improper fraction we need to...</u>
5 x 4 = 20
20 + 1
21/4
Now we divided 21/4 by 7/8.
When dividing fractions remember the rule: KEEP CHANGE FLIP!
We keep the first fraction...which is 21/4 in this case
Change the sign from division to multiplication
21/4 x 7/8
And flip 7/8 so it becomes 8/7
21/4 x 8/7
= 168/28
= 6 loaves
So, the answer is not 6 1/2 loaves (false!)
