Answer: Hello, There! your Answer is Below
40 Is your Answer
Step-by-step explanation:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with XStep 3:
From step 1 above,$80=100
Step 4: Similarly, x=50
Step 5: This results in a pair of simple equations:This results in a pair of simple equations:
$80=100\(1)
$x=50(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
80/x = 100%/50%
Step 7: Again, the reciprocal of both sides gives
x/80 = 50/100
x=40$
Therefore, 50%of 80i s 40

The perimeter of a rectangular picnic area is 590 yards. It is 100 yards wide. How long is it?
Answers
Answer:
195
Step-by-step explan
Answer:
195 yards
Step-by-step explanation:
remember a rectangle has 4 sides.
100 yards wide is how wide 1 side is. so 2 sides are 200 yards wide.
to determine the width you subtract 200 yards from 590 which give you the answer 390. finally to determine just one side of the length you need to divide 390 in two to get 195 yards.

What is the mean absolute deviation for these data?
2.2
6
6.5
8
Answers
Answer:
2.2
Step-by-step explanation:
If you find the mean of the deviation, you get 2.2
The mean absolute deviation of the data is M = 2.2
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the total number of points be n
Now , the value of n = 10
And , the number of points on each data is given by set A
Now , the value of set A = { 7 , 2 , 8 , 5 , 9 , 9 , 5 , 6 , 8 , 1 }
So , the total sum of data = 7 + 2 + 8 + 5 + 9 + 9 + 5 + 6 + 8 + 1
The total sum of data = 60
Now , the mean number of data points = 60/10 = 6
And , the mean deviation is M
M = 1/10 | [ ( 7 - 6 ) + ( 2 - 6 ) + ( 8 - 6 ) + ( 5 - 6 ) + | ( 9 - 6 ) | + ( 9 - 6 ) + ( 5 - 6 ) + ( 6 - 6 ) + ( 8 - 6 ) + ( 1 - 6 ) |
M = ( 1/10 ) [ 1 + 4 + 2 + 1 + 3 + 3 + 1 + 0 + 2 + 5 ]
M = ( 1/10 ) [ 22 ]
M = 2.2
Therefore , the value of M is 2.2
Hence , the mean deviation is 2.2

What is the solution set for -4x-10 ≤ 2?
Answers
Answer:

Step-by-step explanation:
Let's solve your inequality step-by-step.
−4x−10≤2
Step 1: Add 10 to both sides.
−4x−10+10≤2+10
−4x≤12
Step 2: Divide both sides by -4.
−4x /−4 ≤ 12 /−4
= x≥−3
brainliest please?Answer:
x ≥ -3
Step-by-step explanation:
you add 10 on both sides
-4x - 10 ≤ 2
+10 +10
= -4x ≤ 12
then you divide -4 on both sides to get the x by itself
12/-4 is -3
since you divided by a negative you flip the sign
