Answer:
x° = 139
step 1 :
180 - (37 + 38)
= 180 - 75
= 105°
step 2 :
180 - 105
= 75°
step 3 :
180 - 116
= 64°
step 4 : this step to find the value of x
x° = 180° - (64 + 75)°
= 180° - 139°
= 41

Rachel had a loan for $4,000 loan for 4 years.
She paid a total of $608 in simple interest over the 4 years.
What was the annual interest rate for the loan?
9514 1404 393
Answer:
3.8%
Step-by-step explanation:
The interest on a simple-interest loan is ...
I = Prt
where P is the principal value, r is the annual rate, and t is the number of years.
Solving for r, we get ...
r = I/(Pt) = 608/(4000×4) = 0.038 = 3.8%
The annual interest rate for the loan was 3.8%.
What is the volume of a hemisphere with a radius of 3.1 in, rounded to the nearest tenth of a cubic inch?
Pls help me
Answer:
Formula: V = (2/3) π r 3.
Radius is 3cm.
So, now we can plug it in to solve for the volume.
V = (2/3) π 3^3
First, let's multiply 3^3.
3^3 = 27
Then, 27 x π = 84.82
After, multiply by 2/3.
84.82 x 2/3 = 56.55
Lastly, round 56.55 to the nearest tenth of a cubic centimeter.
56.55 = 56.6
Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.

A store selling the calculators donates $90 to charity
from the profit of $500 worth of calculators. If they sell
$200 worth of calculators and donate at the same rate,
how much money would be given to charity?
Answer:
Will be reveled in part B.
Step-by-step Part A
Using O P N Chart for the profits of $500
O P N represent Original, Part Percent and New original.
O $500 ║100%
P $410║-18%
N $90 ║82%
I got $410 which is my part percent by subtracting the original by the New original. (500 - 90 = 410)
Now to solve for the part percent and New original which we will know how much money would be given to charity?
Solving for part percent
Part percent x org = Part
(X) x 500 = 90
500x = 90
500 500
x = 0.18 = 18%.
If they sell $500 worth of calculators and donates $90 to charity they are left with $410 and they gave the charity 82%
Part B:
O: $90 ║ 100%
P: $110 ║-18%
N: $200 ║82%
So this tells me that the charity recived $110.

A walkway forms one diagonal of a square playground. The walkway is 14 m long. How long is a side of the playground?
Answer: The side of the playground is around 10 meters long
Step-by-step explanation:
use the diagonal as the hypotenuse of a right triangle, where the sides of the square form the legs of said triangle.
Usually
[tex]a^{2} +b^{2} =c^{2}[/tex]
since we know a and b are the same length (sides of a square are congruent) we would have
[tex]a^{2} +a^{2} =c^{2} \\2a^{2} =c^{2}[/tex]
We know that c is 14 so
[tex]2a^{2} =14^{2} \\2a^{2} =196\\a^{2} =98\\a=\sqrt{98} \\a= 9.999[/tex]
=[tex]\frac{mv^{2} }{2}[/tex] ; Solve for v.
Answer:
[tex]v=\sqrt{\frac{2E}{m} }[/tex]
Step-by-step explanation:
[tex]E=\frac{mv^2}{2}[/tex]
[tex]2E=mv^2}[/tex]
[tex]v^2=\frac{2E}{m}[/tex]
[tex]v=\sqrt{\frac{2E}{m} }[/tex]

Find the area of the triangle
Answer:
The answer to this problem is 12.5.
Step-by-step explanation:
The formula for finding the area of a triangle is b * h * 1/2 or divide by 2 (base times height times one-half or two).
Since this is a equilateral triangle, all of the sides are equivalent to each other. Since we know one of the sides is 5, all of the sides are 5.
5 * 5 = 25
Then you need to multiply this answer by 1/2 or divide by 2, whichever is easier.
25 / 2 = 12.5
The answer is 12.5.

Given

m(f(x)) = 1/ (2x - 10)The denominator can't be zero
2x - 10 ≠ 02x ≠ 10x ≠ 5The double number line shows the amount of time a hen needs to lay 1 egg.
Complete the table to show the same information as the double number line.

I realize the double number line in this exercise can be as shown in the attached image, in that case, the table, correctly completed is:
Eggs Time (hours)
3 75
4 100
12 300
Method to complete the table.
First, you must see the double number line (attached image), in this we identify a hen needs 25 hours to lay 1 egg, by this reason, to identify the time required for a certain number of eggs, just multiply the number of eggs by 25 (the number of hours shown on the double number line), then:
3 * 25 = 7512 * 25 = 300To calculate the number of eggs taking into account the time, you must divide the hours by 25:
100 / 25 = 4In this way, you can check that the answers are 75, 4, and 300 respectively, to complete the table in the correct form.

At a fundraiser, Marco's class sold 75% of their 80 baked
goods. How many baked goods did they sell?
Answer:
60
Step-by-step explanation:
They sold 60 baked goods because 75% of 80 is equal to 60.
Answer:
60 baked goods
Step-by-step explanation:
To find the answer to this question, you will need to multiply 80 by 75%.
Now this is very simple.
Some calculators will actually give you the option to multiply by a percent. Just type 80×75% and you'll get 60.
There is another way to do this.
You could also just solve 80×.75 due to the fact that .75 is equal to 75%.

4/7(21/8 x + 1/2) = -2(1/7 - 5/28x)
What is x in decimal form?
Answer:
x=[tex]1.22930[/tex]
Step-by-step explanation:
47(218 x+12 ) =−2(17 −528 x)
Simplify 47(218 x+12 ) : 327(21x+4) 327(21x+4) =−2(17 −528 x)
Multiply both sides by 7(21x+4)
327(21x+4) · 7(21x+4)=−2(17 −528 x)· 7(21x+4)
Simplify, 32=−14(17 −528 x)(21x+4)
Solve 32=−14(17 −528 x)(21x+4): x=32+4√589105 , x=32−4√589105 x=32+4√589105 , x=32−4√589105
Answer:
x = 0.5
Step-by-step explanation:
[tex]\frac{4}{7}(\frac{21}{8}x + \frac{1}{2}) = -2(\frac{1}{7} - \frac{5}{28}x)[/tex]
[tex]1\frac{1}{2}x + \frac{2}{7} = - \frac{2}{7} + \frac{5}{14}x[/tex]
[tex]1\frac{1}{2}x - \frac{5}{14}x + \frac{2}{7} = - \frac{2}{7} + \frac{5}{14}x - \frac{5}{14}x[/tex]
[tex]1\frac{1}{7}x + \frac{2}{7} = - \frac{2}{7}[/tex]
[tex]1\frac{1}{7}x + \frac{2}{7} - \frac{2}{7} = - \frac{2}{7} - \frac{2}{7}[/tex]
[tex]1\frac{1}{7}x = - \frac{4}{7}[/tex]
[tex]\frac{1\frac{1}{7}x}{1\frac{1}{7} } = \frac{- \frac{4}{7}}{1\frac{1}{7} }[/tex]
