What is the smaller angle formed by the minute and hour hands at 3:30pm?
the angle would be a 90° angle
========================================================
Explanation:
At 3:00 pm, the hour hand is pointed directly at the '3'. At 4:00 pm, the hour hand moves to point directly at the '4'.
Since 3:30 pm is the halfway point of 3:00 pm and 4:00 pm, this must mean the hour hand is halfway between the '3' and '4'.
Each little tiny tickmark on the clock represents 1 minute. From the "3" to "4", we have 5 tickmarks, so half of that is 5/2 = 2.5
The hour hand is pointing to 2.5 minutes after the 15 minute mark, meaning the hour hand is pointing to the 15+2.5 = 17.5 minute mark.
The span of time from 17.5 minutes to 30 minutes is 30-17.5 = 12.5 minutes.
Divide this over 60 minutes and we get 12.5/60 = 125/600 = 5/24
The 5/24 indicates the fractional amount of 360 degrees being taken up by this angle shown.
So, (5/24)*360 = 75 degrees is the angle measure in this diagram.

Step-by-step explanation:
8x9x20 + 5x5x10
solve this equation using synthetic division x³+2x²+4x+8=0
Answer:
Your answer is.......
x^3 + 2x^2 + 4x + 8=0 Note.. if x=-2 then whole equation is 0
So, (x+2) is one factor.
x^3 + 2x^2 + 4x + 8
=x^2(x+2)+4(x+2)
(x+2)(x^2+4)

it takes three identical water pumps 7 hours to fill a pool, how long would it take two of the same pumps to fill the pool, assuming they all pump at the same rate. please help
Answer:
10.5 hrStep-by-step explanation:
7 hr/3 pumps
So first we want to find the unit rate which would be...
5.25 hr/1 pump
Now that we found the unit rate we are going to multiply it by 2 because there are 2 pumps...
5.25*2=10.5
So our answer is 10.5 hr/ 2 pumps

f(x)=2x^2+9
Find f(-5)
Answer:
59
Step-by-step explanation:
Given
f(x) = 2x² + 9
f ( -5) = 2 * ( -5)² + 9
= 25 * 2 + 9
= 50 + 9
= 59
════════ ∘◦❁◦∘ ════════
Answer = 59════════════════════
Knownf(x) = 2x² + 9
════════════════════
Questionf(-5) = ?
════════════════════
Way to do#as you the x inside the (x) changed into (-5) it means that you need to change the x into -5.
f(-5) = 2(-5)² + 9
= 2 × 25 + 9
= 50 + 9 = 59
#So f(-5) = 59
