Convert 1.5 and 0.8 from meters to millimeters,
1500*800,
A=120,000
The width of rectangle is
and length is 
Step-by-step explanation:
Let,
Width of rectangle = w
Length of rectangle = w+
Perimeter of rectangle = 
Perimeter of rectangle = 2(Length + Width)

Subtracting
from both sides

Dividing both sides by 4

Therefore,
Width of rectangle = w =
cm
Length of rectangle = 
The width of rectangle is
and length is

Answer:
Volume of sphere is 
Step-by-step explanation:
It is given that Hal says that volume of sphere is 
Volume of sphere is given by 




Now using 3.14 in place of 
Now volume of sphere is


Therefore volume of sphere when we use 3.14 in place of
is 
And the Hal likely error is he uses
directly for calculation of volume.
Answer:
0.677
Step-by-step explanation:Add up the values in the plan A column. There are 10+12+16 = 38 people who prefer plan A.
Add up the values in the "40-49" row to find that 16+8 = 24 people are ages 40 to 49.
We have 38+24-16 = 46 people who either prefer plan A, are aged 40-49, or fit both descriptions. I subtracted off 16 because those 16 people were counted twice when adding 38 and 24.
An alternative way to get this value of 46 is to add up everything that is in column1 or row 3 (or both). So that would get 10+12+16+8 = 46.
Now add up everything in the table to find out how many people were surveyed total. That would be 10+7+12+15+16+8 = 68 people overall.
The probability of someone liking plan A, or being age 40-49, or both is 46/68 = 0.6765 approximately. Rounding to 3 decimal places gives 0.677
