Thurman put $90 into an account that pays 4.4% interest, compounded quarterly. According to the rule of 72, approximately how long will it take for his money to double?
Answer:
Number of Years to Double= 15.65
Step-by-step explanation:
Giving the following information:
Interest rate= 0.044/4= 0.011
Annual compound interet rate= (1.011^4) - 1= 0.4473
The rule of 72 is a means of estimating the number of years it takes for an investment or your money to double.
Number of Years to Double= 70/Annual Rate of Return
Number of Years to Double= 70/4.473
Number of Years to Double= 15.65

Equality PropertiesAlgebra I
Composite FunctionsStep-by-step explanation:
Step 1: Define
f(x) = 2x³ + 8
h(x) = ∛(12 - 5x)
(f o h)(x) is f(h(x))
Step 2: Find Composite Function
Substitute: (f o h)(x) = 2(∛(12 - 5x))³ + 8Evaluate: (f o h)(x) = 2(12 - 5x) + 8Distribute 2: (f o h)(x) = 24 - 10x + 8Combine like terms: (f o h)(x) = -10x + 32And we have our final answer!

The ordered pair is a solution of the linear inequality would be; (8,3)
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
We are given that Brigit earns $10 per hour for bagging groceries at a grocery store and $8 per hour for babysitting. She wants to earn at least $80 this week.
Let x is the number of hours she works at the grocery store and y is the number of hours she babysits.
The linear inequality shown in the graph represents this situation as;
10x + 8y ≥ 80
Therefore, the ordered pair is a solution of the linear inequality would be;
(8,3)

Joan sewed 115 fabric squares for her new quilt. Each fabric square was 12 inches by 12 inches. If no fabric square was cut or folded, which statement describes the largest square quilt Joan could make?
Group of answer choices
1.Joan has too many squares for a 9-foot-by-9-foot quilt and not enough squares for a 10-foot-by-10-foot quilt.
2.Joan has too many squares for a 10-foot-by-10-foot quilt and not enough squares for an 11- foot-by-11-foot quilt.
3.Joan has too many squares for an 11-foot-by-11-foot quilt and not enough squares for a 12- foot-by-12-foot quilt.
4.Joan has too many squares for a 12-foot-by-12-foot quilt and not enough squares for a 13-foot-by-13-foot quilt.
Answer:
3.Joan has too many squares for an 11-foot-by-11-foot quilt and not enough squares for a 12- foot-by-12-foot quilt.
Step-by-step explanation:
Given that:
Joan sewed 115 fabrics for her new quilt and each fabric square was 12 by 12 inches, suppose no fabric square was cut or folded, the largest quilt Joan could make was an 11-foot-by-11-foot quilt but not enough squares for a 12- foot-by-12-foot quilt.
A'Reana earns a weekly allowance for doing chores around the house and for keeping all of her grades above a C. During a particular week, she gave $10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50. How much is A'Reana's weekly allowance?
Given :
During a particular week, she gave $10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50.
To Find :
How much is Reana's weekly allowance.
Solution :
Let, allowance is x.
Then by given conditions :
37.50 = x - ( 10 + x/2 + 7.50 )
37.50 = x/2 - 17.50
x/2 = 55
x = $110
Therefore, Reana's weekly allowance is $110.
Hence, this is the required solution.

Round the numbers to estimate the quotient. 29 and one-fifth divided by 4 and StartFraction 6 over 7 EndFraction Which numbers should be used? 25 ÷ 5 The estimated quotient is
Answer:
The quotient is 6.
Step-by-step explanation:
Given two fractions are:
[tex]29\dfrac{1}{5}[/tex]
and
[tex]4\dfrac{6}7[/tex]
To find:
The quotient of
[tex]29\dfrac{1}{5}\div 4\dfrac{6}7[/tex]
Solution:
Formula to convert mixed fraction to a fraction:
[tex]p\dfrac{q}{r} = \dfrac{p\times r+q}{r}[/tex]
Using the above formula to rewrite the given mixed fractions:
[tex]29\dfrac{1}{5}[/tex] can be written as:
[tex]\dfrac{29\times 5+1}5\\\Rightarrow \dfrac{146}{5}[/tex]
[tex]4\dfrac{6}7[/tex] can be written as:
[tex]\dfrac{4\times 7+6}{7}\\\Rightarrow \dfrac{34}{7}[/tex]
Now dividing:
[tex]\dfrac{\frac{146}{5}}{\frac{34}{7}}\\\Rightarrow \dfrac{146\times 7}{5\times 34}\\\Rightarrow \approx 6[/tex]
Therefore the quotient is 6.
Answer:
Round the numbers to estimate the quotient.
29 and one-fifth divided by 4 and StartFraction 6 over 7 EndFraction
Which numbers should be used?
✔ 29

During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.
Answer:
0.75 inches of snow
Step-by-step explanation:
During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.
12 hours = 9 inches of snow
1 hour = x
Cross Multiply
12 hours × x = 1 hour × 9 inches
x = 9/12
x = 0.75 inches
Therefore, 0.75 inches of snow fell at each hour.
Find the values of the variables.
X = ____.
Y = ____.
Please help! I’ll give brainliest to whoever answers first!
Answer:
x = 16 y = 22.627 (or 16[tex]\sqrt{2[/tex])
Step-by-step explanation:
cos(45) = 16/y
y = 16/cos(45)
y = 22.627
tan(45) = 16/x
x = 16/tan(45)
x = 16
*this can also be found because we know this is a right triangle with two angles of 45 degrees. This means that both sides will be equal so x will be 16 and the diagonal will be 16 root 2 (22.627)

Three friends bought 4, 6, and 8 books.
This table shows the cost of the books.
Number of Books 4 6 8
Cost ($) 30 45 60
What is the constant of proportionality?
A. 2
B. 7.5
C. 15
D. 30
Answer:
B:7.5
Step-by-step explanation:
since 4 goes with 30, 6 goes with 45, and 8 goes with 60, you can see that 60-45 is 15 and 45-30 is 15 as well so the constant is 15, but the number of books is going up by two so the constant there is 2. So divide 15 by 2 and the answer would be C: 7.5.

B. 7.5

Cooper took a math quiz last week. There were 76 problems on the quiz and Cooper answered 75% of them correctly. How many problems did Cooper get correct?
Answer:
57 problems
Step-by-step explanation:
Total number of problems = 76
Percentage of problems answered correctly = 75%
The number of problems Cooper got correctly =
75% of 76
= 75/100 × 76
= 57 problems
Cooper got 57 problem correctly
