Teh answer is c just make the 20% into 0.2 then times 0.2 by 30 and you will get cost of the sweater
Answer:

Step-by-step explanation:
Hey there!
Standard form is what this equation is in
Standard form is this: 
So order to complete the square, you need to take the
term out of the equation, divide it by two, and then square it
In this case, the
term is 8
We need to divide 8 by 2 ---> 4
Then square 4 ---> 16
So now you should add 16 to both sides

Now you can simplify the LHS

Now you subtract 16 from both sides

So this is as far as you can go since you cannot take the square root of a negative number
Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24

Add all the sides together
Answer: option D is the correct answer.
Step-by-step explanation:
Let the height of both cones be h
The radius of the base of a right circular cone is 7 times greater than the radius of another right circular cone. If the radius of the smaller cone is r, then the radius of the larger cone is 7r.
The formula for determining the volume of a cone is expressed as
Volume = 1/3(πr²h)
Volume of the smaller cone is
1/3(πr²h)
Volume of the larger cone is
1/3(π ×(7r)²h)
= 1/3(π ×49r²h)
the volume of the larger cone divided by the volume of the smaller cone is
1/3(π ×49r²h) / 1/3(πr²h) = 49/1 = 49
