Step-by-step explanation:

radius = 0.25 inch

Volume of  ceramic ball = [tex]\frac{4}{3}\pi r^{3}[/tex]

                                        [tex]= \frac{4}{3}*3.14*0.25*0.25*0.25\\\\= \frac{0.19625}{3}\\\\=0.07 cubic feet[/tex]

Volume of 200 balls = 200 * 0.07

                                  = 14 cubic feet

1 cubic feet = 2 ounces

14 cubic feet = 2*14 =  28 ounces

There are 32 munchkins in the box. You want to distribute the munchkins to Amir and Isaac so that the ratio of Amir's munchkins to Isaacs is 5:8.

How many munchkins will each person get? Show/explain your work

Answers

Answer:

Amir will get 160/13 or 12 [tex]\frac{4}{13}[/tex] and Isaac will get 20 [tex]\frac{9}{13}[/tex]

Step-by-step explanation:

Lets say that the ratio is [tex]5x:8x[/tex]. Then, let's put this into an equation:

[tex]5x+8x=32[/tex]

Then, if we solve, we get:

[tex]13x=32, x=\frac{32}{13} \text{ or } 2\frac{6}{13}\\[/tex]

Then, we know that Amir's share is [tex]5x[/tex], so [tex]\frac{32}{13}\cdot5=160/13 \text{ or } 12 \frac{4}{13}[/tex].

Then, Isaacs share is [tex]8x[/tex], so [tex]8\cdot\frac{32}{13}=20\frac{9}{13}[/tex]

Hope it helps!!

Answer:

Amir = 12 and Isaac = 20

Step-by-step explanation:

Given

[tex]Amir : Isaac = 5 : 8[/tex]

[tex]Munchkins = 32[/tex]

Required

Amount of munchkins given to each person

For Amir, the amount is calculated as:

[tex]Amir's = \frac{Amir}{Amir + Isaac} * Munchkins[/tex]

[tex]Amir's = \frac{5}{5+8} * 32[/tex]

[tex]Amir's = \frac{5}{13} * 32[/tex]

[tex]Amir's = \frac{5 * 32}{13}[/tex]

[tex]Amir's = \frac{160}{13}[/tex]

[tex]Amir's \approx 12[/tex]

For Isaac, the amount is calculated as:

[tex]Isaac's = \frac{Isaac}{Amir + Isaac} * Munchkins[/tex]

[tex]Isaac's = \frac{8}{5 + 8} * 32[/tex]

[tex]Isaac's = \frac{8}{13} * 32[/tex]

[tex]Isaac's = \frac{8 * 32}{13}[/tex]

[tex]Isaac's = \frac{256}{13}[/tex]

[tex]Isaac's \approx 20[/tex]

A cheetah can run 67.52 feet per second. How fast can a cheetah run in 3.6 seconds? Show your work, write your answer in a complete sentence

Answers

Answer:

hi

Step-by-step explanation:

Well, you would just multiply the feet per second (67.52) by the amount of time (3.6) in order to get the final distance in 3.6 seconds (243.073)

So, a cheetah can run about 243.073 feet in 3.6 seconds

Find the area of the figure and choose the appropriate result.

Answers

Answer:

A- 24m

B- 18.9

C. 11.4

Total- 54.3

Step-by-step explanation:

Answer:

41.7 square meters

Step-by-step explanation:

First, rectangle A:

4 x 6 = 24 square meters

Second, rectangle B:

We know the length of this section is 3.5m. For the height/width, we can look at rectangle C. The height of C is 3.8m, and we see the part of C that is NOT part of B is 2m long. So we subtract 2 from 3.8 to find the height of B.

3.8 - 2 = 1.8m

Then, for the area of B:

3.5 x 1.8 = 6.3 square meters

Third, rectangle C:

3 x 3.8 = 11.4 square meters

Add up areas of A, B, C:

24 + 6.3 + 11.4 = 41.7 square meters

Maria needs 3/4 foot of string to make each bracelet. How many feet of string does she need to make 9 bracelets?

Answers

Answer:

6.75 foot

Step-by-step explanation:

3/4 foot of string is needed for one bracelet so we multiply that with 9:

3/4*9

=27/4

=6.75 foot

If each bracelet needs 3/4 of string therefore in order to make it easier turn the fraction into decimal by dividing the numerator and the denominator which is 0.75 then multiply by the amount of bracelets which is 9 which gets you to 6.75 in a fraction it’s
6 3/4.
hope this helps!

13. A right triangle has sides 8 and 12.


a. Find the missing side if 8 and

12 are legs.


b. Find the missing side if 8 and

12 are a leg and hypotenuse.

Answers

A if 8 and 12 are legs the missing side would be 14.42
B if 8 is a leg and 12 is hypotenuse then the other leg would be 8.94
So the pythagorean theorem is a^2 + b^2 = c^2. in this case it would be 12^2 + 8^2 = c^ 2

Explanation:
12^2 = 144
8^2= 64
64 + 144 = c^2
208 = c^2
in order to find c we need to square root both sides of the equation, you can plug that into the calculator.
c = about 14.4

A car costs $30,000 when purchased as new and depreciates at a rate of 18% per year.

1. Write an exponential decay model to represent the situation. Be sure to define the variables.
2. Find the value of the car after 10 years.

Answers

9514 1404 393
Answer:
v(t) = 30000×0.82^t . . . value in dollars after t years
v(10) ≈ 4123 . . . . dollars
Step-by-step explanation:
The general form of the decay model is ...
f(t) = f(0)×(1 -decay rate)^time
where the decay rate is a fraction between 0 and 1, and the time is expressed in the same time units as the decay rate. The multiplier f(0) is the initial value that is decaying.
In this problem, the initial value is $30,000 and the decay rate is 18% per year. So, we can write a function v(t), where v is the car's value in dollars, and t is the number of years after it starts depreciating.
v(t) = 30,000×(1 -0.18)^t
v(t) = 30,000×0.82^t
__
The car's value in 10 years is ...
v(t) = 30,000×0.82^10 ≈ 4123.44
The value of the car after 10 years is about $4,123.
