the answer gotta be b or d
You have the first part correct. The area 36pi comes from squaring 6 to get 36.
The diameter 12 is cut in half to get the radius 6.
Add on 3 to the radius to get 3+6 = 9. The new radius is 9 which squares to 81. That's why the answer is choice D for the problem on the right.

Answer:
B
Step-by-step explanation:
Answer choices:
A and T
WCR and TRA
<-----> WC <----> CR
<-----> WC <----> WT
Answers
WCR and TRA are angles. For any triple the points do not fall on the same straight line. So we cannot define any lines here. This crosses off choice B
Choice C is the answer because WC does define a line. We only need two points to form a line. Similarly CR does the same job. We draw a line marker with two arrows at each end to be placed over the letters to indicate "line".
Choice D is similar to choice D; however, it is not the answer because WT is the same line as WC. In other words, WC = WT. We haven't named a new line at all. We're simply repeating ourselves.

The unit rate for $18 for 24 pounds
Answers
Final answer:
To find the unit rate of $18 for 24 pounds, you divide the total cost by the number of pounds, resulting in a unit rate of $0.75 per pound.
Explanation:
The student is asking how to calculate the unit rate of a product that costs $18 for 24 pounds. To find the unit rate, you divide the total cost by the total number of units (in this case, pounds). So, the calculation for the unit rate in this question would be:
$18 ÷ 24 pounds = $0.75 per pound
Thus, the unit rate is $0.75 per pound. This means for every pound of the product, you pay $0.75.

although you should have an option that either is 11^5 or equals 11^5 like 11^15/11^10 for example
the third answer is almost correct, but it would have to be 11^5/11^0
Answer:
[tex]11 .11^4[/tex]
Step-by-step explanation:
Given phrase,
11 to the 8th power over 11 to the 3rd power
[tex]\implies \frac{11^8}{11^3}[/tex]
[tex]=11^{8-3}[/tex] [tex](\because \frac{a^m}{a^n}=a^{m-n})[/tex]
[tex]=11^5[/tex]
Since,
[tex]11.11^4[/tex]
[tex]=11^{1+4}[/tex]
[tex]=11^5[/tex]
Hence, the equivalent expression to 11 to the 8th power over 11 to the 3rd power is,

A company has the pay scales below , with the percent of employees receiving that pay listed. Find the best value to represent an average salary at this company. ( round to the nearest dollar ) Job Salary Percent of Employees Entry $30,000 60% Expert $40,000 38% CEO $125,000 2%
Answers
Job Salary % of Employees
-------- ------------ ----------------------
Entry $30,000 60%
Expert $40,000 38%
CEO $125,000 2%
Let n = total number of employees.
Entry:
Number = 0.6n
Pay total = 0.6n*(30,000) = $18,000n
Expert:
Number = 0.38n
Pay total = 0.38n*(40,000) = $15,200n
CEO:
Number = 0.02n
Pay total = 0.02n*(125,000) = $2,500n
Total pay = 18,000n + 15,200n + 2,500n = $35,700n
Average salary = 35,700/n = $35,700
Answer: $35,700
Subtract using the number line.
−1/3 − (−1/2)
Answers
The answer is 1/6 after using the number line if the number expression is −1/3 − (−1/2).
What is a number line?It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.
It is given that:
The fraction numbers are 1/3 and -1/2
As we know,
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
The number expression is:
−1/3 − (−1/2)
From the number line:
Drawing line segment length of 1/3 left side
Drawing line segment length of 1/2 left side
Taking difference using number line:
= 1/6
Also, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= −1/3 − (−1/2)
= -1/3 + 1/2
= (-2+3)/6
= 1/6
Thus, the answer is 1/6 after using the number line if the number expression is −1/3 − (−1/2).

Pauline spent $7.50 every day for 3 days. Which expression is the best choice to help her determine the total amount of money she spent?
(7.50)(−3) = −22.50; she spent $22.50
(−7.50)(3) = −22.50; she spent $22.50
(−7.50)(−3) = 22.50; she spent $22.50
(7.50)(3) = 22.50; she spent $22.50
Answers
Answer:
The correct option is 2.
Step-by-step explanation:
It is given that Pauline spent $7.50 every day for 3 days.
Amount spent on each day = $7.50
Number of days = 3
Spent amount and expenditure are always negative.
Total amount of money she spent is
[tex]Total =(-7.50)(3)[/tex]
On simplification we get
[tex]Total =-22.50[/tex]
She spent $22.50 and required expression is (−7.50)(3) = −22.50. Therefore the correct option is 2.
How many 1/4 ft pieces can you cut from a string that is 15 feet long
Answers
so the answer is 60 pieces
You can cut 60 pieces of 1/4 foot each from a string that is 15 feet long by carrying out the operation 15 ÷ 1/4, which turns into multiplication by the reciprocal of the fraction, 15 x 4 equals 60.
Explanation:The question is asking how many 1/4 ft pieces you can cut from a 15 feet long string. In other words, you want to divide the total length of the string by the length of each piece you're cutting out. So you will carry out a division operation: 15 ÷ 1/4. When dividing by a fraction, you actually multiply by its reciprocal. The reciprocal of 1/4 is 4, so 15 ÷ 1/4 becomes 15 × 4, which equals 60. Therefore, you can cut 60 pieces of 1/4 foot each from a string that's 15 feet long.

Answers
Let me know if I wrong
The $2500 money must you deposit in a simple interest account to earn $500 in interest in 5 years at 4% annual interest.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
It is given that:
simple interest account to earn $500 in interest in 5 years at 4% annual interest
As we know the simple interest formula is:
I = Prt
Here
I = $500
t = 5 years
r = 4% = 0.04
500 = P(0.04)(5)
P = 500/0.2
The money that must be deposited in a simple interest account to earn $500 is:
P = $2500
Thus, the $2500 money must you deposit in a simple interest account to earn $500 in interest in 5 years at 4% annual interest.

Which reason justifies the statement that KLC is complementary to KJC?
Answers
hope it helps
Answer:
Angles that are congruent are complementary to the same angle
Step-by-step explanation:
see that attached figure to better understand the problem
we know that
Two angles are complementary if their sum is equal to [tex]90\°[/tex]
[tex]m<KJM=m<KLM=90\°[/tex]
[tex]m<KJC=m<MLC[/tex] -----> equation A
[tex]m<KJM=m<KJC+m<CJM[/tex]
so
[tex]m<KJC+m<CJM=90\°[/tex] -----> equation B
[tex]m<KLM=m<KLC+m<MLC[/tex]
so
[tex]m<KLC+m<MLC=90\°[/tex] -----> equation C
Substitute equation A in equation C
So
[tex]m<KLC+[m<KJC]=90\°[/tex]
That means------> angles ∠KLC and ∠KJC------> are complementary angles
therefore
Angles that are congruent are complementary to the same angle
