Answer:
4.013 units
Step-by-step explanation:
We know that the volume of a cone is given by the following equation:
v = pi / 3 * r ^ 2 * h
we need to know the height, therefore we solve for h:
h = 3 * v / (pi * r ^ 2)
replacing v = 105 and r = 5
h = 3 * 105 / (3.14 * 5 ^ 2)
h = 4.013
Which means that the height measures 4.013 units
The given expression is
-2x² + 17 - 15x + 7xy
The algebraic expression may be written as
-2x² + 7xy - 15x + 17
The constant term does not contain either x or y.
Therefore 17 is the constant term.
Answer: 17
I think it’s asking for you to multiply (-3,7) and (7,-8)
So if it is it would be -21 times-56= 1,176 AB=1,176

Step-by-step explanation:
Answer:
The total money she saved in a year = X + 12Y.
Step-by-step explanation:
Mary got a piggy bank as a gift.
Sum of money in the piggy bank while she got it as a gift = X cents
Sum of money she saved = Y cents per month
1 year = 12 months
So, sum of money she saved in 1 year = Y × 12
= 12Y
Hence, the total money she saved in a year = X + 12Y.
