Answer:
P(x) = 3x - 150
Step-by-step explanation:
Step-by-step explanation:
P(x) = R(x) - C(x)
Given:
R(x) = 5x
C(x) = 2x + 150
P(x) = 5x -(2x+150)
P(x) = 5x - 2x -150
P(x) = 3x - 150 <- Answer
A plastic skeleton is
Answer: B. a physical model.
The world has lots of different kinds of models. A mathematical model might be a ball travels according to the equation
. This isn't that. A computer model would be a program that somehow simulates a skeleton in the computer, this isn't that either. Our skeleton is an actual physical model just like a model airplane.
Answer:
1) 8 : 343
2) 42.875 or 42 ⅞
3) 4 : 49
4) 16ft²
Step-by-step explanation:
Volume of cube: s³
Surface area of cube: 6s²
_____________________
32ft^3 and 1372ft^3 →
32 : 1372 = 8 : 343
343 / 8 = 42 ⅞ = 42.875
s³ → 6s²
s³ = 8, s = 2, s² = 4.
s³ = 343, s = 7, s² = 49.
These are proportional so it is already in the simplest ratio so it is not necessary to multiply by 6.
s³ → 8 : 343
6s² → 4 : 49
(4 / 49) × 196ft² = 16ft²
Answer:
C. 114
Step-by-step explanation:
bikes have 2 wheels
skateboards have 4 wheels
incline skates have 8 wheels in total
7*2 = 14
9*4 = 36
8*8 = 64
if you add all of these up you get 114 wheels in total. 8*8 was from 24-7-9 = 8
IT's just a simple conversion.
.
Ok. So, when you divide with decimal places, you have two options -
.
Suck it up and divide, or move the decimal places to the right as many times as needed, until the number is a whole number.
.
Choosing to move the decimal places to the right is the easy way out...
.
So?
.
Move decimal point to the right two places in both numbers!!
.
80 and 64.
.
So what is 80/64?
.
You got it!!
.
1.25.

Hope I helped!!
