Answer:
1. 600 x 20 x 20=240000
2. Jason should say "Find the product of 4 x 5 and then add all of the remaining zeroes in the problem to your answer. This results in 400,000 x 50,000= 20,000,000,000."
Step-by-step explanation:
The ice cream cone consists of a semi-circle with a diameter of 10 cm and a triangle with a base of 10 cm and height of 12 cm.
The area of a semi-circle is half the area of a full circle, so we can find it by using:

If the diameter of the circle is 10 cm, then the radius is 5 cm. Plug in the known values:


or about 39.25
The area of a triangle is:

So we can plug in the known values to find the area to be:

When we add the areas of the two sections together, we get an exact answer of:
(60 + 12.5pi) cm^2
or about
99.25 cm^2
Answer:
3rd choice
Step-by-step explanation:
In division for variables with same base, you do subtract top exponent minus bottom exponent. She did that correctly since -3-(-1)=-3+1=-2 and -2-1=-3.
The problem said m=-2 and n=4 and she replace m with (-2) and n with (4). She did this correctly.
You can multiply base numbers unless the exponents are the same 4 doesn't have the exponent -2 on it so you can't do (4(-2))^(-2)
The error is the 3rd option.
Answer:
0
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
= (10-10)/(1-4)
= 0/-3
=0
4000 (4x10^3) times 400 (4x10^2) is equal to 16x10^5 ( 1,600,000)
