Answer:
24.30 Difference, sale price 56.70
Step-by-step explanation:
30% off 81.00 is 56.70
The difference is 24.30
Answer:
The solution to this question is 39
Step-by-step explanation:
Given that :
√(3x+7)+2√(x-8)=0.
√(3x+7)=-2√(x-8) (i)
square of the equation (i)
Then
(√(3x+7))^2=(-2√(x-8))^2
we know that √a*√a=(√a)^2=a So,
(3x+7)=4(x-8)
3x+7=4x-32 //multiply by 4
32+7=4x-3x exchange the value.
39=1x
x=39.

When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:
Step 1. Twice the difference of a number and 2
Let's call that unknown number as n. Then, twice the difference of a number and 2 is:

Step 2. Twice the difference of a number and 2 is at most -27

So the mathematical form of the statement <em>twice the difference of a number and 2 is at most -27 </em>is:

Answer:
you need the formula for the cone , Korc
Step-by-step explanation:
formula for cone =
*π*
*h
they tell us that the diameter is 8 so r = 4
and that h = 9
volume of cone =
*π*
*9
VoC = 150.796
VoC = 150.8 ( to the nearest 10th)
