Answer:
We have 252 different schedules.
Step-by-step explanation:
We know that as a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses, and one of seven physical education courses.
So from 4 lab science courses we choose 2:

So from 2 literature courses we choose 1:

So from 3 math courses we choose 2:

So from 7 physical education courses we choose 1:

We get: 6 · 2 · 3 · 7 = 252
We have 252 different schedules.
A (b-c)=d
ab-ac=d
ab-d=a.c
Divide both sides by a
Your answer = ab-d/a
Answer choice C
Let's solve your equation step-by-step.
4(2x+8)=10x+2−2x+30
Step 1: Simplify both sides of the equation.
4(2x+8)=10x+2−2x+30
(4)(2x)+(4)(8)=10x+2+−2x+30(Distribute)
8x+32=10x+2+−2x+30
8x+32=(10x+−2x)+(2+30)(Combine Like Terms)
8x+32=8x+32
8x+32=8x+32
Step 2: Subtract 8x from both sides.
8x+32−8x=8x+32−8x
32=32
Step 3: Subtract 32 from both sides.
32−32=32−32
0=0
Answer:
All real numbers are solutions.
Answer:
I think the answer is C. 1209 cm^3
Step-by-step explanation:
volume of a cylinder= πr^r2xh
radius = 1/2xdiameter
r = 1/2× 9
r = 4.5cm
height. = 19cm
volume of the cylinder = 22/7 x (4.5)^2 x 19
= 1208.73cm^3
= 1209 cm^3 ( to the nearest whole number)
