Answer:
a. False
b. True
c. True
d. I think it's true
e. False
Step-by-step explanation:
a. The unit rate is 19.75 gallons per minute
b. It is true because when x=0 y is also equal to 0, therefore it passes through the origin
c. 19.75 is about 20, and 20 multiplied by 5 is 100
d. Like I said before I don't know but I hope you get it correct ._.
e. When x=8 the equation would be 19.75*8 which is equal to 158 not 150
Answer: 3.66 cm
Step-by-step explanation: Given a rectangular casing BCDE with segment DE = 3 cm and segment BE = 3.5 cm.
The area A of a rectangle is length multiply by width.
Where length L = 3.5 cm and
width W = 3 cm
Area A = 3.5 × 3 = 10.5 cm^2
The pipe that will fit the fiber optic line is in cylindrical shape. Where area of a cylinder = πr^2.
But area A = 10.5. Substitute the values for the area of the cylinder
10.5 = πr^2
10.5 = 3.143 × r^2
Make r^2 the subject of formula
r^2 = 10.5/3.143
r = sqrt ( 3.34225 )
r = 1.828
Diameter = 2 × radius
Diameter = 2 × 1.829
Diameter = 3.656 cm
Therefore, the smallest diameter of pipe that will fit the fiber optic line is 3.66 cm approximately.
Answer:
$394.38
Step-by-step explanation:
the formula is I=PRT the trick here is converting the rate from 7% to a decimal. its 0.07. so you have I=(939)(.07)(6)=394.38
