Answer:
10 : 3
Step-by-step explanation:
Convert one of the measurements so that it is in the same form as the other. (Easiest to convert m to cms so we are not working with decimals)
2.5 m = 2.5 x 100 = 250 cm (since there are 100 cm in a meter)
Therefore, as a ratio:
250 : 75
We can divide both by 5:
50 : 15
We can further divide by 5:
10 : 3
(no further simplifying)
So 2.5 m to 75cm as a ratio is 10 : 3
Answer:
1236.6 mm
Step-by-step explanation:
formula is 1/2 (b)(h)
1/2(54)(46.8)
since they are all equal sides
the type of triangle is equilateral triangle
Answer:
The student took 2.5 minutes to paint 1 square foot.
Step-by-step explanation:
In order to know how long the student took to paint each square foot we first need to know the total area of the bulletin board. Since it is a rectangle we can compute it's area by multiplying the width and the height. That is:
area = 2*3 = 6 square foot
Since the student took 15 minutes to paint the whole board the pace at which he was working can be calculated by dividing the total area of the board by the time he took to paint all of it. So we have:
pace = 6/15 = 0.4 foot/min
To find how long it took him to paint 1 square foot we can divide it by the pace he was painting. We have:
time = 1/0.4 = 2.5 minutes
The student took 2.5 minutes to paint 1 square foot.
Marlene is playing Skee Ball at her favorite arcade. She wants to determine the likelihood that she'll roll a ball into each hole. So, she rolls several times and records her results in the following table.
<span><span>Points ScoredFrequency</span><span>1023</span><span>2012</span><span>306</span><span>408</span><span>501</span></span>
A. On any given roll, the experimental probability that Marlene will get 30 points is <span>0.60.20.120.06</span>.
B. On any given roll, Marlene is most likely to get 10000000
