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]
In Winter of 2020 there were 20 total inches of snow. In Winter 2021 there were 38 total inches of snow. What was the percer
increase in inches of snow from 2020 to 2021?
To find the answer, you need to subtract the total inches of snow in 2021 by the total inches of snow in 2020.
So 38 -20= 18
Therefore, from 2020 to 2021. The snow increased by 18 inches.

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]
[tex]x = -\frac{1}{2}[/tex]
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.

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%.

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.

= 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

The 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.
Eggs Time (hours)
3
100
12
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.

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%.
