To Acquire
The Value of 20/4+8/3
Firstly ,we need to find out the LCM of the denominators
12
Now,
We've to Multiply the numerator with the number which is divisible by the resulting LCM from the respective denominator
just like ,here ,12/4 = 3 so we'll Multiply 3 by the numerator of 4 i.e 20 => 20*3 = 60
We'll apply the same thing with the other one
12/3=4 => 4*8 = 32
Now ,we will add the resulting numerators and will keep it in a fraction with the denominator = LCM of 4&3=12
60+32/12
92/12
46/6
23/3

The test score for a class are shown. What is the average test score? 79,80,92,92,81,100,88,98,71,100,91,90
Oksanka [162]
Answer:
The average score is equal to 88.5
Step-by-step explanation:
we know that
An average test score is the sum of all the scores on an assessment divided by the number of test-takers.
so
The sum is equal to
![Sum=[79+80+92+92+81+100+88+98+71+100+91+90]=1,062](https://tex.z-dn.net/?f=Sum%3D%5B79%2B80%2B92%2B92%2B81%2B100%2B88%2B98%2B71%2B100%2B91%2B90%5D%3D1%2C062)
The number of test-takers is n=12
The average score is equal to
substitute
Answer:
14km
Explanation
11km + 11km = 22km is the sum of both the width.
If you want to find the length than minus the perimeter with 22.
50km - 22km = 28km is the sum of both the length.
To know only one side of the length, divide it by 2.
28km/2 = 14km is the length
Hey there! :)
Answer:
170 cm².
Step-by-step explanation:
This is an example of a composite figure, so find the areas of each shape separately:
Begin by finding the area of the smaller square. A = s²
A = 7² = 49 cm².
Find the area of the larger square:
A = 11² = 121 cm².
Add up the two areas:
49 + 121 = 170 cm².
Answer:
-15
Step-by-step explanation:
-24 + (1-4)^2 (solve parentheses first)
= -24 + (-3)^2 (solve exponent)
= -24 + 9
= -15
