Answer:
$5.47
Step-by-step explanation:
Given data:
Annie has 4 dollar , 11 dimes, 4 pennies.
Tommy has 3 dimes, 3 pennies.
To add the money, let us first convert dime and penny into dollar.
1 dollar = $1
11 dime = $1.1
4 penny = $0.04
3 dime = $0.3
3 penny = $ 0.03
Total money = Annie’s money + Tommy’s money
= $4 + $1.1 + $ 0.04 + $0.3 + $0.03
= $5.47
So, they have $5.47 in all.
well, if the diameter is 5, thus its radius must be half that, or 2.5, and therefore, the radius of the one four times as much will be (4)(2.5).
Let's simply get their difference, since that'd be how much more is needed from the smaller to larger sphere.

Answer:
B. y = | x + 15.5 |
Step-by-step explanation:
The + inside the absolute value equation really means -.
So there is a horizontal shift of 15.5 units left.
Lets find out...
-5 - (-2) = -5 + 2 = -3....-3 is greater then -5
-1 - (-3) = -1 + 3 = 2.....2 is greater then -1
-4 - (-2) = -4 + 2 = -2...-2 is greater then -4
so it looks like it is going to be greater then the number u started with.
