Question 1
Total budget = 180 + 475 + 15 + 50 + 65 + 25 + 150 + 30 = $990
Real spending = 182 + 475 + 12 + 65 + 68 + 12.50 + 150 + 36 = $1000.5
Mae Green didn't stay within the allocated budget

Question 2
Eleanor:
Income = 380.48
Spending = 16.50
Peter:
Income = 120 + 13.65 + 100 = 233.65
Total income = 233.65 + 380.48 - 16.50 = 597.63
-------------------------------------------------------------------------------------------------------------
Question 3
Total spent = 540 + 48.55 + 34.15 + 12.80 + 18.95 + 38.60 + 2 + 6.50 = 701.55
-------------------------------------------------------------------------------------------------------------
Question 4
Marie's new balance = 250.65 - [21.95+48.50+75.60] + 55 = $159.50
------------------------------------------------------------------------------------------------------------
Question 5
[235/825] × 100 = 28.48%
A. True. There are 52 cards total and you only pick 5. Order doesn't matter.
-------------------------------------------
B. False. Order doesn't matter so you use a combination (instead of a permutation) as choice A shows.
-------------------------------------------
C. False. The answer is roughly 0.000858 as shown by the calculation below
(13/52)*(12/51)*(13/50)*(12/49)*(11/48) = 0.000858
-------------------------------------------
D. False. See calculation below
(13/52)*(12/51)*(11/50)*(10/49)*(9/48) = 0.000495
-------------------------------------------
E. True. See calculation below
(13/52)*(12/51)*(11/50)*(10/49)*(9/48) = 0.000495
this value rounds to roughly 0.0005
Answer:
Step-by-step explanation:
"f (x) = StartRoot 4 x + 9 EndRoot + 2" should be written as
Note that √(4x + 9) is a variation of the basic function y = √x, whose domain is [0, ∞ ).
The domain of f(x) = √(4x + 9) + 2 is found by taking the "argument" 4x + 9 of √(4x + 9) and setting it equal to zero:
4x + 9 ≥ 0, or
4x ≥ -9, or
x ≥ -9/4
This is the domain of the given function f(x) = √(4x + 9) + 2. So long as x is ≥ -9/4, the function f(x) will be defined.

Answer:
15 miles per hour
Step-by-step explanation:
First, lets find the number of miles he goes in 1 minutes.
That would be found by dividing the number of miles (12) by the number of minutes (48), so we have:
12/48 = 0.25 miles per minute
We want the speed in miles PER HOUR.
So, how many minutes are in an hour??
That is 60 mins = 1 hr
So, we need to multiply this by 60.So,
0.25 miles per minute * 60 minutes (1 hr) = 15 miles per hour
