Can someone help me with this? I don't understand?

shutvik [7]

Answer:

Step-by-step explanation:

∛(1000)² = find the cubed root of 1000 squared 1000 times 1000

∛1,000,000 = ∛ (100 x 100 x 100) = 100

But I think they want use to use exponents to solve the problem

1000^2/3 recall 1000 = 10^3 which is 10x10x10

replace 1000 with 10^3

so

(10^3)^2/3 exponents multiple and divide some rule as I recall

you look it up in your book or on your computer

10^(3)(2)/(3) the 3s divide to 1 leaving the 2 in the exponent

= 10^2 which is 10² which is 100

A total of 20 quarters and nickels add up to $4.00. How many nickels are there?

mariarad [96]

Answer:

5 nickels

Step-by-step explanation:

You can setup and solve a system of equations, or you can solve by trial and error until you get the correct answer.

Here is the solution by trial and error.

If all 20 coins are quarters, the value is 20 * $0.25 = $5

That is too much value.

Let's try 16 quarters. 16 quarters are worth 16 * $0.25 = $4.

That is the correct value, but it is only with quarters, and only 16 of them.

We need fewer quarters than 16.

Try 12 quarters: 12 * $0.25 = $3.00

The number of nickels is: 20 - 12 = 8

8 nickels are worth 8 * $0.05 = $0.40

12 quarters and 8 nickels are worth $3.00 + $0.40 = $3.40

There are 20 coins, but the value is too low.

The number of quarters is between 12 and 16.

Try 14 quarters and 6 nickels:

14 * $0.25 + 6 * $0.05 = $3.50 + $0.30 = $3.80

We are closer to $4 but not there yet.

Try 15 quarters and 5 nickels.

15 * $0.25 + 5 * $0.05 = $3.75 + $0.25 = $4

The total value is $4 and there are 20 coins. This is the answer.

15 quarters and 5 nickels works.

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 8 liters of natural oil for every 5 liters of

Ludmilka [50]

Answer: 370 liters

Step-by-step explanation:

Given : Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 8 liters of natural oil for every 5 liters of synthetic oil.

Then , the amount of Petrolyn oil made by above composition = $8+5=13\text{ liters}$

Also, the amount of petrolyn oil is proportional to the amount of synthetic oil.

Let x be the amount of synthetic oil need ot make 962 liters of Petrolyn oil, the we have the following equation:-

$\dfrac{x}{962}=\dfrac{5}{13}\\\\\Rightarrow\ x=\dfrac{5\times962}{13}=370$

Hence, In order to make 962 liters of Petrolyn oil, 370 liters of synthetic oil is needed .
