The answer is B, 30 x 5 The answer is reasonable. Ryder is correct. It reasonable because if 25 x 5 is 125, then 30 x 5 won't be too much to be unreasonable. 30 x 5 is 150, therefore it is only 25 windows higher, so it is reasonable. Hope this helps! :)
I am lead to believe th =e answer would be 10,000 :)
Compatible numbers is used to find estimate to a sum. The numbers are chosen because its 'simplicity' when they are multiplied, divided, added or subtracted.
Estimate one:
We can decrease the value 1322 to 1320 and 18 to 15
Then do the sum = 1320÷15 = 88
This estimate is not far from the actual answer 1322÷18 = 73.44..
Estimate two:
We can increase 1322 to 1330 and 18 to 20
Then do the sum 1330÷20=66.50
This estimate is also not far from the actual answer 73.44...
Since each unit cube I gives the value of oneI would multiply 48x1.Your answer would be 48
SOLUTION:
Step 1 :
In this question, we are meant to find what percent of 142 is 58.
Step 2 :
We make the assumption that 142 is 100 % since it is our output value.
Step 3:
We next represent the value we see with x.
Step 4 :
From step 2, it follows that 100 % = 142.
Step 5 :
In the same vein, x % = 58.
Step 6 :
This gives us a pair of simple equations:
Step 7 :
By simply dividing equation 1 by equation 2 and
taking note of the fact that the Left-Hand Side of both equations have the same unit ( % ), we have that :
Step 8 :
Taking the inverse ( or reciprocal ) of both sides yields:
CONCLUSION:
Therefore, 58 is 40.85 % of 142.
