At a race, there are 3 rows with 15 people in each row. How many total people are there?
Numerical expression- 15 times 3
(Idk if this helped very much but it's worth a shot)
Answer: 110
Reasoning: all of the numbers should add up to 360.
140+110=250
360-250=110
The angles of 110 look the same, go for it.
Answer:
about 314.16 units squared
Step-by-step explanation:
The formula for area is A = πr^2. Plugging in r, the radius, we get A = π10^2. Evaluating π*10, we get A = [about] 314.16^2.
If the problem asks you to plug in 3.14 for pi, the answer is 314 units squared.
Answer:
ln(3) + 5 - 3ln(x) or 6.0986 - 3ln(x)
Step-by-step explanation:
= 
, since ln(x/y) = ln(x)-ln(y)
= ln(3) + 
, since ln(xy) = ln(x) + ln(y)
= ln(3) + 
= 
, since ln(
) = yln(x)
= ln(3) + 5 -3ln(x) , since ln(e)=1
if needed further simplification,
ln(3) = 1.0986
ln(e) = 1
= 6.0986 - 3ln(x)
