Answer:
1. c. 628 cubic cm
2. c. 502 cubic inches
Step-by-step explanation:
1.) 3.14 x 5^2 x 8
3.14 x 25 x 8 = 628
2.) 3.14 x ( 8/2 )^2 x 10
3.14 x 4^2 x 10
3.14 x 16 x 10 = 502.4
Complete question :
What is the mean change in the forecasted low temperatures? Remember, this can be found by averaging the values in the Difference column for the low temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between. Here are my temps Date High Low 9/13 84 75 9/12 96 75 9/11 93 78 9/10 91 77 9/9 92 76 9/8 93 77 9/7 91 77
Answer:
76.428 ; between 76 and 77
Step-by-step explanation:
Given the data :
Date ____ High _____Low
9/13_____ 84 _______75
9/12 ____ 96 _______75
9/11 _____ 93 _______78
9/10 _____ 91 _______77
9/9 ______92 ______ 76
9/8 ______ 93 ______ 77
9/7 _______91 ______ 77
Mean low temperature :
(75+75+78+77+76+77+77) / number of days
535 / 7
= 76.428
Hence, the mean is between ; 76 and 77
If a right triangle is 90° , the other acute triangle would be 10° because 90 - 80 = 10
Answer:
Step-by-step explanation:
f(3)=2*3^2 - 3*3^2 + 1
=2*9 - 3*9 + 1
=18-27+1
=19-27
=-8
The easiest way to do this, is to go ahead and convert our fractions to decimals, meaning we divide 2 by 12, and 2 by 14. This helps us have all our measurements in the same form so we can just plug them into our formula.
The formula for a rectangular prism is really easy:
V=L*W*H
Volume=Length times Width times Height.
.16*4*.14= 0.09 (Roughly)
Please keep in mind I only used the tenths, and hundredths place; the actual answers are much longer.
