Label each recursive routine as growth or decay (loss) and identify the percent of growth or decay.
a. Start with: 30
Rule: multiply by 1.07
growth by ????? percent
b. Start with: 100
Rule: multiply by 0.86
decay by ???? percent
c. Start with: 75
Rule: multiply by 1.125
growth by ?????? percent
Answer:
a. Rule: multiply by 1.07
1.07 = 107% = 100% + 7%
Growth by 7%
b. Rule: multiply by 0.86
0.86 = 86% = 100% - 14%
Decay by 14%
c. Rule: multiply by 1.125
1.125 = 112.5% = 100% + 12.5%
Growth by 12.5%

Answer:
B
Step-by-step explanation:
The formula for a area of the first semi circle is
[tex] \frac{1}{2} \times \pi {r}^{2} [/tex]
where r is the radius
Since 4 is the diameter, 2 is the radius
plug it in
[tex] \frac{1}{2} \times \pi {2}^{2} [/tex]
[tex] \frac{1}{2} \times 4\pi[/tex]
[tex]2\pi[/tex]
so the area of the first circle is 2
[tex]2\pi[/tex]
now let find the second circle
Since the semi circle is twice the area of AB the diameter is 8 so the radius is 4.
Put it in the equation.
[tex] \frac{1}{2} \times \pi {4}^{2} [/tex]
[tex] \frac{1}{2} \times \pi \times 16[/tex]
[tex]8\pi[/tex]
Now let find the third circle
Since it is twice the size of the second circle, the diameter is 16 and the radius is 8.
[tex] \frac{1}{2} \times \pi {8}^{2} [/tex]
[tex] \frac{1}{2} \times 64\pi[/tex]
[tex]32\pi[/tex]
Now let add the area of the semi circle
[tex]32\pi + 2\pi + 8\pi = 42\pi[/tex]

Amal has 1/2 pound of baked beans. She divides the beans into 8 equal servings. Write and solve an equation to find how many pounds of baked beans are in each serving
Answer:
1/16 pound or 0.0625 pound beans.
Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Total baked beans = 1/2 pounds
Number of serving = 8
if distribute equal beans in each serving than,
8 serving = 1/2 pound
So, 1 serving = 1/(2×8) pound
= 1/16 pound or 0.0625 pound beans.
Hence, each serving consist of 0.0625 pound baked beans.

Wanda, the owner of an e-commerce site, buys skateboards for $50 and then sells them on her site for $83. What is the mark-up, as a percentage?
Answer: 66%
Step-by-step explanation:
Wanda buys the boards at $50 and sells them as $83.
The markup in actual dollar amounts is:
= 83 - 50
= $33
In percentage terms, the denominator will be the cost price:
= Markup / Cost price * 100%
= 33 / 50 * 100%
= 66%
