Answer:
+2
Step-by-step explanation:
kinda obvious
The volume (V) is given in terms of length (L), width (W), and height (H) by the formula ...
... V = LWH
Substituting your dimensions, you have
... V = (11.3 cm)·(18.9 cm)·(29 cm) = 6193.53 cm³ ≈ 6200 cm³
_____
The factor 29 cm has 2 significant digits, so that is the precision required of the answer. It could also be written with less ambiguity as to precision as 6.2 L. (Trailing zeros to the left of the decimal point are always ambiguous when it comes to significant digits.)
Answer:
330(D)
Step-by-step explanation:
So lets go over what we know:
#1: 44 out of 80 people think they have a average fitness level.
#2: 80 out of the 600 people in the school were surveyed.
Using what we know, lets try and find the answer.
So lets divide the total amount of people, by the amount of people that took the survey:
600/80
=
7.5
Ok, so now we know that we need to take 7.5 surveys to find out what all the students think of their fitness level.
Now lets take teh amount of people in a single survey, with average fitness(44), and multpliy it by how many surveys are needed for the whole school(7.5):
44*7.5
=
330
This is the amount of people in the whole school who think they have an average fitness level.
I hope this helps! :)

Answer:
45
Step-by-step explanation:
3x+x has to add up to 180
3x+x=180
4x/4=180/4
x=45
Answer:
-5^x + 3x - 2.
Step-by-step explanation:
(f - g) (x) = f(x) - g(x)
= -5^x - 4 - (-3x - 2)
= -5^x - 4 + 3x + 2
= -5^x + 3x - 2.
