Answer:

You would get 50 coins in that time.

Step-by-step explanation:

To find this, we first need to find the unit rate. We can get that by dividing the amount of coins by the amount of time.

15 coins/ 30 mins = .5 coins per minute.

Now, we have 100 minutes in the second part of the problem, so we multiply the rate by that amount of time.

.5 coins per min * 100 mins = 50 coins

It takes 212121 minutes for 555 people to paint 777 walls. How many minutes does it take 333 people to paint 555 walls?

Papessa [141]

Solution: We are given that:

5 people can paint 7 walls in 21 minutes

Therefore, 1 person can paint 7 walls in $21 \times 5=105$ minutes

Which means 1 person can paint 1 wall in $\frac{105}{7} =15$ minutes

Now, 3 people can paint 1 wall in $\frac{15}{3} =5$ minutes

Therefore, 3 people can paint 5 walls in $5 \times 5=25$ minutes

3^3 times 3^3 divides by 3^4 3^0 3^1 3^2 3^4

USPshnik [31]

Answer:

3^2

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

$\dfrac{(3^3)(3^3)}{(3^4)}=3^{3+3-4}=\boxed{3^2}$
