Answer:
B
Step-by-step explanation:
Perimeter of the composite shape = ½ of the circumference of a circle + perimeter of a rectangle - Length of the rectangle
= ½*2πr + 2(L + W) - L
Where,
r = 8
π = 3.14
L = 16
W = 12
Perimeter of the composite shape = ½(2*3.14*8) + 2(16 + 12) - 16
= 25.12 + 56 - 16
Perimeter of the composite figure = 65.12 inches
Area of the composite figure = ½(πr²) + L*W
= ½(3.14*8²) + 16*12
= 100.48 + 192
Area = 292.48 square inches

A newsletter publisher believes that less than 25% of their readers own a Rolls Royce. For marketing purposes, a potential advertiser wants to confirm this claim. After performing a test at the 0.05 level of significance, the advertiser decides to reject the null hypothesis. What is the conclusion regarding the publisher's claim
Answer:
There is enough evidence at the 0.05 significance level that the percentage is less than 25%.
Step-by-step explanation:
The question has no options. However, there are enough details to arrive at a conclusion.
Required
What can we conclude about the claim of the publisher.
From the question, we understand that the null hypothesis is rejected.
In statistics, a hypothesis is rejected, if the level of significance is less than the required or determined value.
In this case, the determined value 25% and the level of significance is 0.05
So, the conclusion on the claim is that there is enough evidence at the 0.05 significance level that the percentage is less than 25%.

2n < 40
Divide each side by 2
2n/2 < 40/2
n < 20

-2x-3y=-7
y=6x-11
If someone answers this and shows work I will give Brainlyest
Answer:
x = 2
y = 1
Step-by-step explanation:
-2x-3y=-7, y=6x-11
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-2x - 18x = -40
-20x = -40
x = 2
y = 6(2) - 11
y = 12 - 11
y = 1
Answer:
x = 2, y = 1
Step-by-step explanation:
We have a system of equations:
-2x - 3y = -7
y = 6x - 11
Substitute the given value of y into the equation -2x - 3y = -7
-2x - 3 * (6x - 11) = -7
-20x = -7 - 33
-20x = - 40
x = 2
Substitute the given value of x into the equation y = 6x - 11
y = 6x - 11
y = 6 * 2 - 11
y = 1
For the function y = -x2 – 2, how can you find the value of y when x = 3?
Answer:
y=-3x2-2

One face of a cube-shaped package has an area of 7 5/8 square inches what is the lateral surface area of the package in square inches
Answer:
232.57 square inches
Step-by-step explanation:
The computation of the lateral surface area of the package in square inches is shown below;
Let us assume the area of cube is a
Given that
a = [tex]7 \frac{5}{8}\ in^2[/tex]
As we know that in a cube there is a four faces so the lateral surface area would be
[tex]= 4a^2\\\\=4\times 7\frac{5}{8} ^2\\\\= 4\times (\frac{61}{8})^2\\\\= 4\times \frac{3721}{64} \\\\= 232.57[/tex]
= 232.57 square inches

Step-by-step explanation:
a^7/a^13
=1/a^6
=1/(a^2)^3
= 1/ 3√(a^2)^3
=1/(a^2)
(c^3)^3
=3√(c^3)^3
=(c^3)
hence as these results matches so I think option b is correct.

Using the scientific calculator or graphing calculator find the inverse tangent of the ratio. Round to the nearest degree. 3/1
Given:
The ratio is [tex]\dfrac{3}{1}[/tex].
To find:
Inverse tangent of the given ratio.
Solution:
We know that,
Inverse tangent of the ratio [tex]\dfrac{3}{1}[/tex] = [tex]\tan^{-1}\dfrac{3}{1}[/tex]
= [tex]\tan^{-1}3[/tex]
Using scientific or graphing calculator, we get
Inverse tangent of the ratio [tex]\dfrac{3}{1}[/tex] = [tex]71.565^\circ[/tex]
Round to the nearest degree
Inverse tangent of the ratio [tex]\dfrac{3}{1}\approx 72^\circ[/tex]
Therefore, the correct option is C.

Jonathon saves $4,000 at the end of each quarter for 10 years. Assume 12% compounded quarterly and find the present value.

Kaitlyn hopes to attend a college where tuition is $24,000 per year. She believes that tuition will increase at 4% for the 3 years until she plans to enter college. Find the quarterly payments needed to accumulate funds to pay the first year’s tuition if funds earn 8% compounded quarterly.
A. $1,597.20
B. $34.05
C. $2,012.87
D. $2,561.30
Answer:
Results are below.
Step-by-step explanation:
1. First, we need to calculate the Future Value:
FV= {A*[(1+i)^n-1]}/i
A= quarterly deposit
n= 10*4= 40
i= 0.12/4= 0.03
FV= {4,000*[(1.03^40) - 1]} / 0.03
FV= $301,605.04
Now, the present value:
PV= FV/(1+i)^N
PV= 301,605.04/(1.03^40)
PV= $92,459.09
2. First, we need to calculate the value of the first year of college:
FV= PV*(1+i)^n
FV= 24,000*(1.04^3)
FV= $26,996.74
Now, the quarterly payments:
FV= {A*[(1+i)^n-1]}/i
A= quarterly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
i= 0.08/4= 0.02
n= 3*4= 12
A= (26,996.74*0.02) / [(1.02^12) - 1]
A= $2,012.87

In a shop, there were 4 times as many guppies as swordtails. After 23 guppies and 27 swordtails were added, there were 83 more guppies than swordtails. What was the total number of fish in the shop at first?
Answer:
145
Step-by-step explanation:
Assume the number of sword tails is x. Then the number of guppies is 4x.
After 23 guppies and 27 swordtails were added. Then guppies = 4x+ 23
swordtails = x+27
According to the relation 83 more guppies than swordtails. We can obtain:
[tex]4x + 23 = x + 27 + 83[/tex]
4x-x= 27+83-23
3x=110-23
3x=87
x=29
There are 5x fish in total at first.
5x=5*29=145
so the number of fish in the shop at first is 145
Show how to use the distributive property to simplify 4(5+x)
Step-by-step explanation:

Hey there!
The Distributive Property states the following:
a(b+c)=ab+ac
Where
a, b, and c can be either variables or constants
Now that we know what the property states, let's simplify our expression:
4(5+x)
4 times 5 and 4 times x:
20+4x
Hence, the answer is
[tex]\boxed{\boxed{\bold{20+4x}}}[/tex]
Hope everything is clear,
Let me know if you have any other questions.
