Answer:
<u>The correct answer is B. 3/4</u>
Step-by-step explanation:
In the expression 5n - 2m/7+ 3/4, what is the constant?
Let's analyze the coefficients, variables, operators and constants, as follows:
A. Coefficients:
5 is coefficient for n and 2/7 is coefficient for m
B. Variables:
n and m
C. Operators:
- between 5n - 2m/7
+ between 2m/7+ 3/4
D. Constant:
3/4 that is not affected by any variable
<u>The correct answer is B. 3/4</u>
F = 3/r.
The formula for the volume of a cylinder is
V=πr²h. We know that h=2r, so this gives us:
V = πr²(2r) = 2πr³
The surface area of a cylinder is the sum of the areas of all of the faces. The bottom and top are circles, whose areas are both given by A=πr². The lateral area of a cylinder is given by the circumference multiplied by the height. C = 2πr, and the height is 2r, so the lateral area would be
A=(2πr)(2r)= 4πr². This gives us a total surface area of
SA = 4πr²+πr²+πr² = 6πr².
The ratio of surface area to volume would be:
SA/V = 6πr²/2πr³. After simplifying, we have f=3/r.

Step-by-step explanation:
0.657/9= 0.073
Answer:
a = -8
Step-by-step explanation:
19 = -3a - 5
Add 5 to both sides.
24 = -3a
Divide both sides by -3.
-8 = a
Switch sides.
a = -8
