I used 9.8 pints of blue paint and white paint to paint my bedroom walls 4/5 of this amount is blue plate and the rest is wiping how many pints of white paint did you use to paint her bedroom walls

Answers

Answer:

searth it up duh

Answer:

Amount of white paint used to paint bedroom walls = [tex]1.96[/tex] pints

Step-by-step explanation:

Total amount of blue paint and white paint = 9.8 pints

Amount of blue paint used to paint bedroom walls = [tex]\frac{4}{5}[/tex]

Amount of white paint used to paint bedroom walls = [tex]1-\frac{4}{5}=\frac{1}{5}[/tex]

Therefore,

Amount of white paint used to paint bedroom walls = [tex]\frac{1}{5}(9.8)=1.96[/tex] pints

Which is the correct representation of 6/1?​

Answers

I think it’s B I’m not sure

The correct representation of 6/1 is in figure A.

Given:

The four figures with shaded regions and unshaded regions.

To find:

The figure with the correct representation of 6/1.

Solution:

In figure A

Fraction of one box =[tex]\frac{1}{1}[/tex]

There are six individual boxes that will be represented as:

[tex]\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}=\frac{6}{1}[/tex]

In figure B

The number of shaded regions = 5

The total number of regions = 6

The representation will be :

[tex]\frac{\text{Shaded region}}{\text{Total regions}}=\frac{5}{6}[/tex]

In figure C

Fraction of one box =[tex]\frac{1}{1}[/tex]

There are five individual boxes that will be represented as:

[tex]\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}+\frac{1}{1}=\frac{5}{1}[/tex]

In figure D

The number of shaded regions = 1

The total number of regions = 1

The representation will be:

[tex]\frac{\text{Shaded region}}{\text{Total regions}}=\frac{1}{6}[/tex]

The correct representation of 6/1 is in figure A.

Answers

Answer:

x = 6, ∠ B = 126°

Step-by-step explanation:

∠ A and ∠ B are alternate angles and congruent, so

8x + 78 = 2x + 114 ( subtract 2x from both sides )

6x + 78 = 114 ( subtract 78 from both sides )

6x = 36 ( divide both sides by 6 )

x = 6

Then

∠ B = 2x + 114 = 2(6) + 114 = 12 + 114 = 126°

The length of the hypotenuse (x) is an irrational number between 6 and 8. Both legs have measured that are whole numbers. What is one possible set of measures for the sides of the right triangle

HELP ME PLEASE !

Answers

Step-by-step explanation:

Since 6 < x < 8, we have 36 < x² < 48.

Let a and b be the sides of the right triangle.

a²/b² could be 1², 2², 3², 4², 5² and so on.

A possible set of measures is 6 and 2.

This will give x² = 6² + 2² = 40, x = √40 which is irrational.
