Explain how you would find a precent increase or a percent decrease.


don't put I don't know or I don't know or ill report you

Answers

Answer:

You can find a percent increase because the percentage would go up. Like 30% if it increased it would go up too 50%. Which increased by 80%. And you can also add and subtract to make sure your answer is correct.

To find a deacrease it means that the percentage would go down. Like 80% to 60% is a decrease because it went down by 20%.

Painting:
Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 square feet. Write and solve a proportion to determine how many gallons of paint Lisa will need


(Also can you explain how you solved it? Just in case I've been doing all the other ones wrong)

Answers

Answer:

Step-by-step explanation:

First we need to find the area of the fence, since paint covers square feet and squared units refers to area.  The area of the fence is 26 x 7, which is 182 sq ft.  If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom. 1/350 = x/182  Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.

A gallon of paint with cover 365

Which ratio is greater, 4:5 or 3:4?

Answers

4:5
explanation-

Express the given ratios as fraction

4 : 5 = 4/5 and 2 : 3 =2/3

Now find the L.C.M (least common multiple) of 5 and 3

The L.C.M (least common multiple) of 5 and 3 is 15.

Making the denominator of each fraction equal to 15, we have

4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15

Clearly, 12 > 10

Now, 12/15 > 10/15

Therefore, 4 : 5 > 2 : 3.

The answer is subtract two from both sides. Explanation: because it males the equation even and easier to solve.

Answer:

[tex] \underline{ \underline{ \boxed{ \text{Subtract \: 2 \: from \: both \: sides}}}}[/tex]

Step-by-step explanation:

Since we want constants only on the right hand side , we have to remove 2 which is on the left hand side. The opposite of +2 is -2 and whatever we do to one side , we must do to the other side. So, The first step that would be used to solve the equation should be Subtract 2 from both sides.

11 1/8
Explanation
The answer comes out to 11.125 however in mixed number form it’s 11 1/8

Answer:

11 and 1/8

Step-by-step explanation:

We can do this in the format of PEMDAS

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

10 + (2 × 3[tex])^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]

Let's do the parenthesis first

10 + [tex]6^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]

Now we can do the fraction with the exponent second

10 + [tex]6^{2}[/tex] ÷ 4 ×  [tex]\frac{1}{8}[/tex]

Now we can do the other exponent

10 + 36 ÷ 4 × [tex]\frac{1}{8}[/tex]

Now we can divide the 36 and 4

10 + 9 × [tex]\frac{1}{8}[/tex]

Now we can multiply the 9 and  [tex]\frac{1}{8}[/tex]

10 + [tex]\frac{9}{8}[/tex]

And we can convert the improper fraction to a mixed number

10 + 1 1/8

And now we can add them up, the 2 whole numbers and the fraction stays the same

11 1/8

Hope this helped!
