Answers

Answer:
y= 12x-16
Step-by-step explanation:
Given that you have a slope of 12 and a point of (3, 20), you are most obligated to using the Slope-Intercept form, or y=mx+b.
What this allows you to find is the y-intercept if your line has one. You take your point, (3,20), and you insert the values at the appropriate places. You should now have 20=12(3)+b. You will then solve for b by multiplying 12 and 3 to get 36 and subtract that from both sides of the equal sign. You should have 20-36=b. 20-36 is -16, which is your y-intercept.
Your answer would be Y=12x-16

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%.

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.

Answer:

4:5

what is the surface area of the box if it is scaled up by a factor of 10?
list dimensions

Length: 9.5 inch which is 24 cm

Width: 2.8 inch which is 6 cm

Height: 13 inch which is 33 cm

Answers

A for a box, the surface area is given by:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in

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

What is the value of the expression shown below?

25 and 1/6
69
82

Answers

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!
