What is the answer to this question, also can you explain it please

Answer:

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

Step-by-step explanation:

x = amount of 4% fuel

6 - x = amount of 20% fuel

0.04x + 0.2(6 - x) = 0.08(6) Multiply both sides by 100 to remove the decimals

4x + 20(6 - x) = 8(6)

4x + 120 - 20x = 48

-16x + 120 = 48

-16x = -72

x = 4.5

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

Answer:

i'm assuming it's 2*√5(13+√2) so 2√10+26√5

Step-by-step explanation:

The product of 2 square root 5 (13 + square root 2) in simplified form is 26√5 + 2√10

From the question, we have the following parameters that can be used in our computation:

2 square root 5 (13 + square root 2)

Express as products

So, we have

2√5 * (13 + √2)

Open the brackets

So, we have

2√5 * (13 + √2) = 2√5 * 13 + 2√5 *√2

Multiply the radicands

So, we have the following

2√5 * (13 + √2) = 2√5 * 13 + 2√10

Evaluate the products

So, we have the following

2√5 * (13 + √2) = 26√5 + 2√10

Hence, the solution is 26√5 + 2√10

Answer:

$44.16

Step-by-step explanation:

total amount to pay = $38.40 + (0.15)($38.40)

                                 = $38.40 + 5.76

                                 = $44.16

You can also just put 38.40 * 1.15 and you will get the same answer

A TV that usually sells for $170.09 is on sale for 15% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?

Find the discounted price: 15% off of 170.09

Discounted Price = 170.09 * (1 - 0.15) <-- 15% as a decimal is 0.15, and 1 is 100%. So, we subtract to get 85% of the original price.

Discounted Price =170.09(0.85)

Discounted Price = $144

Now, add in the sales tax of 6% to the Discounted Price.

Price after sales tax = Discounted Price * 1.06

Price after sales tax = $144 * 1.06

Price after sales tax = $152.64
