The true statements are:
There are 56 fluid ounces of milk left.
There is more than 1 / 4 gallon of milk left.
What are the true statements?
The first step is to convert gallons to cups.
1 cup = 16 gallons
Then, convert quarts to cups
1 quart = 4 cups
1 1/2 x 4
3/2 x 4 = 6 cups
Total cups left = 16 - 6 - 3 = 7 cups
1 cup = 8 ounces
Total milk left in ounces: 8 x 7 = 56 ounces
1 cup = 1/16 gallons
Total milk left in gallons: 1 / 16 x 7 = 7/16 gallons

Bob wants to take his wife, Mary, to Europe in three years to commemorate their 40th wedding anniversary. He recently received a $25,000 inheritance from an uncle, which he plans to put towards the trip. Bill calculates that the trip will cost $30,000 and that he can earn 6% yearly compound interest on his investment. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1, FVAD of $1, FVAD of $1, FVAD of $1, FVAD of $1, FVAD of $1, FVAD of $1, FVAD of $1, F (From the tables provided, select the appropriate factor(s).)
To calculate the future value, fill out the table below. Will he be able to pay for the trip with the money he has saved up? (Round up your totals to the nearest whole dollar amount.)
Answer:
10%
Explanation:
Use future value formula
Future Value = Present Value ((1+r)^n)
26,600 = 20,000 ((1+r)^3
26,600/20,000 = (1+r)^3
1.33 = (1+r)^3
1.33^1/3 = 1+r
1.0997 = 1+r
1.0997 - 1 = r
r = 0.997 = 9.97% = 10% (rounded of to the nearest whole percentage)

The current salaries in Sasha's department are $42,000, $32,000, $33,000, $38,000, and $50,000. Sasha wants to adjust the lowest salary up to $40,000. If Sasha gives every employee a $1,000 raise in addition to adjusting the lowest salary, Find the total cost for the increment?
The total cost for the increment if Sasha gives every employee a $1,000 raise in addition to adjusting the lowest salary is $13000.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
The lowest salary is $32000, hence to increase to $40000, we need an additional $8000.
Also, giving every employee a $1,000 raise accounts for $5000 since there are 5 staff.
The total cost of increment = 8000 + 5000 = 13000

The price of a new shirt was slashed from N1 500 to N1 250. Find the percentage decrease in the price of the shirt.
Answer:
The percent decrease is 16.67%.
Step-by-step explanation:
percent change = (new price - old price)/(old price) × 100%
percent change = (N1250 - N1500)/(N1500) × 100%
percent change = -250/1500 × 100%
percent change = -16.67%
A negative percent change is a percent decrease.

A study of a local high school tried to determine the mean amount of money that each
student had saved. The study surveyed a random sample of 69 students in the high
school and found a mean savings of 5000 dollars with a standard deviation of 1400
dollars. At the 95% confidence level, find the margin of error for the mean, rounding
to the nearest whole number. (Do not write ).
Using the t-distribution, it is found that the margin of error for the 95% confidence interval is of $336.
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The margin of error is given by:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]
The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 69 - 1 = 68 df, is t = 1.9955.
The standard deviation and sample size are given, respectively, by:
s = 1400, n = 69.
Hence, the margin of error in dollars is given by:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]

A football stadium holds 17,700 seats. The lower level has 300 seats less than 4 times the number of seats in the upper level. The middle level has 500 more seats than twice the number of seats in the upper level. Let x represent the seats in the upper level. Which equation can be used to find the number of seats in the upper level?
7 x + 200 = 17,700
6 x + 200 = 17,700
7 x minus 200 = 17,700
6 x minus 200 = 17,700
Answer:
6x + 200 = 17,000
Step-by-step explanation:
Lower level = 4x - 300
Mid level = 2x + 500
Combine the two equations to find the number of seats in the upper level
(2x + 500) × (4x - 300) = 17,000
Combine like terms
4x × 2x + 500 - 300 = 17,000
6x + 200 = 17,000
find the area and the circumference of a circle with the diameter 6 yards
Answer:
area = 28.27
circumference = 18.85
Step-by-step explanation:
Using the formulas for area,
A = πr^2
d = 2r
Solving for area,
A = 1/4 πd^2 = 1/4 × π × 6^2 ≈ 28.27yd²
Using the formulas for circumference,
C = 2 πr
d = 2r
Solving for circumference,
C = πd = π × 6 ≈ 18.85yd
The function fis defined as follows.
f(x)=2x²+3
If the graph of fis translated vertically downward by 6 units, it becomes the graph of a function g.
Find the expression for g(x).
The expression of the translated function g(x) is gotten as; g(x) = 2x² - 3
How to Interpret Graph Translations?
We are given the function;
f(x) = 2x² + 3
Now, when we translate a function f(x) downwards, the new function becomes;
g(x) = f(x) - a
where a is the amount of units by which the graph was translated.
Thus for translation of 6 units vertically downwards;
g(x) = 2x² + 3 - 6
g(x) = 2x² - 3

Jack invested $2,100 in an account paying an interest rate of 7\tfrac{5}{8}7 8 5 % compounded monthly. After 12 years, how much more money would Jack have in his account than Maya, to the nearest dollar?
This are interest added on a sum of money invested. Jack will have $168.95 more than Maya in his account
Compound interestThis are interest added on a sum of money invested. The formula for calculating compound amount is given as;
A = P(1 +r/n)^nt
Given the following parameter
P =$2100
rate r = 7 5/8% = 0.07625
time t = 12 years
n =12 (monthly)
Substitute
A = 1200(1+0.07625/12)^12(12)
A = 1200 (2.4895)
A = $2987.46
For Maya
A = 1200(1+0.07375)^12
A = 2818.50
Take the difference
Difference =$2987.46 - $ 2818.5
Difference = $168.95
