3 to the power of 5

you multiply 3 times 5 instead of 3 times 3 times 3 times 3 times 3

Say the equation is 5 to the 2nd power +7 you would multiply the 5x2 which is 10 then + 7 =17

krek1111 [17]

So Volume (V) of a sphere is:
$V = \frac{4}{3} \pi {r}^{3}$
so essentially we need to divide the machine's Volume (V) the gumball volume (v)
$V = \frac{4}{3} \pi {r}^{3} = \frac{4}{3} \pi {(6)}^{3} \\ V = \frac{4}{3}(216) \pi = 288\pi$
$v = \frac{4}{3} \pi {( \frac{1}{3} )}^{3} = \frac{4}{3} \times \frac{1}{27} \pi \\ v = \frac{4}{81} \pi$
now we divide V by v:
$V/v = \frac{288\pi}{ \frac{4\pi}{81} } = \frac{288}{1} \times \frac{81}{4} = 5832$
so b) 5,832 gumballs can fit in the machine

Miguel quiere entrenar para la carrera solidaria de verano en uno de los dos parques que tiene cerca de casa. Su plan es correr

kondor19780726 [428]

Answer:

The square park is more convenient.

Explanation:

The translation of the question is:

Miguel wants to train for the summer solidarity race in one of the two parks that he has close to home. His plan is to run about 10 km each day and he wants to do an exact number of laps around the park to always start and end at the entrance. Since he has not quite decided between the square and the rectangular park, he decides to do some calculations to see which one suits him best.

Square park: 423 meters each side

Rectangular park: 673 meters measures the base and 218 meters the height

<h2>Solution</h2>

1. Calculate the perimeter of the square park

The perimeter of a square is the sum of the four side lengths. Since they are equal it is:

Perimeter = 4 × side lenght

Perimeter = 4× 423m = 1,692 m

2. Calculate how many times 1,692m is in 10 km

10 km is 10,000 m. Then, divide 10,000 by 1,692 m:

Number of laps = 10,000m / 1,692m ≈ 5.91 laps

3. Calculate the perimeter of the rectangular park

Perimeter = 2×base + 2×height

Perimeter = 2×673m + 2×218m = 1,782m

4. Calculate how many times 1,782 is in 10km

Number of laps = 10,000m / 1,782m ≈ 5.61 laps

Then, since the number 5.91 is closer to an integer number than 5.61, you conclude that the square park is more conventient, because by running 6 laps around the square park the number of kilometers run will be closer to 10 km than with any number of complete laps in the rectangular park.

Karen buys 8.5ounds of flour. She uses 2.5 pounds to bake bread. she keeps the rest of the flour in small storage baga. If each

NISA [10]

Karen bought 8.5 pounds of flour. She uses only 2.5 pounds of flour to make the bread.
So, the amount of flour left after baking the bread = (8.5 - 2.5) pounds
= 6 pounds
So 6 pounds of flour is left. She breaks this 6 pounds of flour into several bags and each bag contains 2/5 pound of flour.
Now to calculate the 2/5 th pound of flour in decimal, we get = 0.4 pounds
So each of the bags contain 0.4 pounds of flour. Now we have to calculate the number of bags in which the flour have been kept.
So,
Number of bags required = 6/0.4
= 15
So 15 small storage bags are required by Karen to keep the remaining flour.
