Answer 1

Answer:

70.71 cm²

Step-by-step explanation:

There are two faces that are not painted.

They are rectangles with one side 5 cm, and another side 7.071 cm.

Total of not painted surface area is:

2*5*7.071 = 70.71 cm²
Answer 2

Answer:

[tex]\Large \boxed{\sf 70.71 \ cm^2}[/tex]

Step-by-step explanation:

Jackson had previously painted 6 faces of the cube.

The unpainted faces are the 2 faces inside the cube that is made when the cube is cut.

Area of the unpainted section is required.

The 2 faces are rectangles

[tex]2 \times (5 \times 7.071)=70.71 \ \sf cm^2[/tex]

Step-by-step explanation:

The owner of a tree service has a chainsaw that uses a mixture of 200 ounces of gasoline and 2 ounces of oil. The owner needs to make at least
5 gallons of the oil-gasoline mixture.
If the owner knows that l gallon is equal to 128 fluid ounces, which inequality can be used to determine the amount of oil needed?

Answers

Answer:

You need 6oz (or 6.3366oz) of oil for the 5 gallon mixture.

Step-by-step explanation:

First, write down the essentials of this word problem.

The chainsaw uses 200 ounces gasoline (or gas) and 2 ounces oil.

The owner needs 5 gallons (640 ounces) of the mixture.

The chainsaw uses a 202 ounce mixture (200oz gasoline 2oz oil).

The mixture is 0.0099 repeating % oil and 0.9900 repeating % gasoline.

0.0099 (oil) x 640 (final mixture) = 6.3366oz repeating oil needed.

0.9900 (gas) x 640 (final mixture) = 633.6633 repeating gas needed.

This means you need 6.3366oz or 6oz (rounded) for the 5 gallon mixture.

CHECKING WORK:

6.3366 + 633.6633 = 639.99999997

OR ROUNDED:

6 + 634 = 640

Step-by-step explanation:

When you do 45 divided by 9 you get 5.

                         45 / 9 = 5

     To figure out what the smaller number (in this the 4) equals,

Step-by-step explanation:

We know that % means a 100 so if they say they allowed a 5% discount then that would be 5/100.

You will take the fraction and multiple it with the original price. It will then give you the discount price, you will then need to subtract the discounted amount from the original sale price which is 5225. Then you will get your final answer.
