Actually the answers A since t is for text messages and it costs .15 and m is minutes and costs .07 so we add those two together to he .15t+ .07m then there's a discount of 2.50 so we subtract. So our final equation is .15t + .07m - 2.50 = C
Distributive property, since 3(2x) you distribute and get 6x
Answer:
6 * m
Step-by-step explanation:
6m is is multiplication so should be the equivalent expression
Written out as words clearly says
six times a number
times meaning multiplication
Meaning any other expression is equivalent as long as it is a form of multiplication
If I'm wrong please tell me if not
Hope this helped :]
1/x=6/21
What you need to do is set it up as a proportion. 1 cup to 6 cups cake mix, x cups to 21 cups cake mix.
21/6 is 3.5
So 3.5 cups of water to 21 cups of cake mix (:
Hope this makes sense!
Answer:
The volume of the cone is:
- <u>112.6 cubic inches.</u>
Step-by-step explanation:
You should know that the volume of a straight circular cone is equal to:
- Cone volume = (1/3) PI * r ^ 2 * h
Where:
<em>r = radius.
</em>
<em>h = height.
</em>
Since the radius and diameter are not provided in the exercise but the circumference, the circumference formula should be used and the diameter must be cleared:
- Circumference = PI * Diameter.
When clearing you get:
- Diameter = circumference / PI
By replacing the data you get:
- Diameter = 15 inches / PI
- Diameter = 4.77 inches.
Since the radius is equal to half the diameter, then the diameter is equal to 2,385 inches, now having the value of radius we proceed to replace in the volume formula:
- Cone volume = (1/3) PI * 2.385 in^2 * 18.9 in
- Cone volume = 112.581541 in^3
- <u>Cone volume = 112.6 in^3</u>
