If it takes 5 1/4 minutes to make one cut through a log, how long will it take to cut a 5 ft log into 5 equal pieces?
Answers
Answer:
131.25
Step-by-step explanation:
5.25*(5*5)
Answer:
How many cuts are needed to cut the log into 5 equal pieces.
Hopefully you figure out that it takes 4 cuts.
Now if it takes 20 minutes in total then each cut would take how long.
Divide the total time by number of cuts.
So each cut takes 5 minutes.
Now figure out how many cuts are needed to get ten equal pieces and multiply by 5 minutes

Step-by-step explanation:
128 is there and the other angles are right angles (90 degrees). 90 plus 90 is equal to 180. 180 plus 128 is equals to 308 degrees. Any quadrilateral is 360 degrees. 360 minus 308 is equal to 52 degrees
Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.
His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.
In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.
Assuming there are no outliers or skew, do the results support Garret's theory?
Select from the drop-down menus to correctly complete the statements.
Since the samples were large and randomly chosen, we can use the samples to understand the populations.

What is the result of factoring out the greatest common factor from the polynomial 15u3 + 9u2v - 18uv2?
a
3uv (5u^2 + 3u - 6v)
b
3u (5u^2 + 3uv - 6v^2)
c
uv (15u^2 + 9u -18v)
d
u (15u^2 + 9uv - 18v^2
Answers
Answer:
B
Step-by-step explanation:
By looking at the problem, we can realize that all the three terms share the constant 3 and the variable u, so 3u is our GCF. Now, we factor out 3u, and divide each term by 3u to show what's left:
3u( 15u^3 / 3u + 9u^2v / 3u - 18uv^2 / 3u)
15u^3 / 3u --> 5u^2
9u^2v / 3u --> 3uv
- 18uv^2 / 3u --> -6v^2
3u(5u^2 + 3uv - 6v^2)
This aligns with option B, so B is the answer.

Cara likes candles. She also likes mathematics and was thinking about using algebra to answer a question she had about two of her candles. Her taller candle is 16 cm tall. Each hour it burns makes the candle lose 2.5 cm in height. Her short candle is 12 cm tall and loses 1.5 cm in height for each hour that it burns.
Write an equation for both candles and solve it by either substitution or elimination.
(If someone could please help me out with this, I would really appreciate it. I've been trying to do this for days now and I just can't figure it out..)
(By the way, the equation for the 16 cm candle is y = -2.5x + 16, and the equation for the 12 cm candle is y = -1.5x + 12, I just don't know how to solve it using substitution or elimination.)

+100 , where

s is the distance above the ground in feet and
t
t represents time in seconds. According to this model, how many seconds does it take for the ball to hit the ground? Round to the nearest tenth if necessary.
Answers
Answer:
6.25 seconds
At ground level the height of ball is 0, i.e., h=0.
Using zero product property, we get -16t -100
= -16t + 100 + 100s
= -16(t + 6.25) -16(ts + -6.25)
= 6.25s
