Answer:
Step-by-step explanation:
Part A:
Mark did not round to the nearest hundreds, he rounded to the nearest tens.
Option A (Incorrect):
271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.
Option B (Incorrect):
271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.
Option C (Incorrect):
271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.
Option D (Correct):
271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.
Part B:
There are two ways to solve this question:
One way:
271 + 582 = 853
Round 853 to the nearest hundred for 900
(Note: Round 853 to the nearest tens for 850.)
Second way:
271 + 582
Round Numbers:
300 + 600
= 900
Answer:
Volume of a sphere = 4/3πr³
π = 3.14
r = radius which is 3in
Volume = 4/3 × 3.14 × 3²
= 37.68
= 38 cubic inches to the nearest hundredth
Hope this helps
Answer:
Step-by-step explanation:
We need to find the LCM of 24, 72.
LCM
= Multiply all the factors
= 3 × 2 × 2 × 2 × 3
= 72.
First, we do 30 dollars per 1 hour times 35 hours per 1 week.
30*35 = 1050 dollars per 1 week
now, we do 1050 dollars per 1 week times 50 weeks per 1 year.
1050*50 = 52500 dollars per 1 year
finally, we divide 52500 dollars per 1 year by 1,000,000 dollars earned overall and we get the fraction
400/21
that doesn't come out to an exact decimal, so we get either
400/21 years or the rounded decimal of
19.0476 years
so, approximately 19 years.
Answer:
Number of males: 30
Number of females: 14
Step-by-step explanation:
Let x be the number of males
Males: x
Females: x - 16
x + x - 16 = 44
2x = 44 + 16
2x = 60
x = 30
Males: 30
Females 30 - 16 = 14
