Lin runs 5 laps a track in six minutes how many minutes per lap is that
Answer:
1.2 minutes
Step-by-step explanation:
6 divided by 5 = 1.2
To do this, you take the total number of minutes, which is 6, and divide by the number of laps that Lin ran, which was 5.
Answer:
1.2 minutes
Step-by-step explanation:
5 laps/6 minutes = 1 lap/x minutes
To convert the ratio from 5 laps to one laps, 5 was divided by 5. Therefore, to keep the same ratio, 6 must also be divided by 5, making the answer:
1 lap/1.2 minutes

Find the volume of the cylinder. Use 3.14 for pi. Round your answer to the nearest tenth.
Answer:
The formula for the volume of a cylinder is V=Bh (where B is the base) or V=πr2h . The radius of the cylinder is 9 ft and the height is 6 ft. Substitute 9 for r and 6 for h in the formula V=πr2h = (3.14) (9) (2) (6) =339.12
Step-by-step explanation:
Now C=339.12 round to the nearest tenth is 339.1

There are 1,240 skittles in a bag, 25% are blue, .22 are red, 1/3 yellow and 1/5 are purple. Which color is least likely to be picked?
Step-by-step explanation:
[tex] \frac{1}{3} = 0.3333...[/tex]
[tex] \frac{1}{ 5} = 0.2[/tex]
[tex]25\% = 0.25[/tex]
0.22=0.22
[tex]0.2 < 0.22 < 0.25 < 0.33...[/tex]
0.2 (1/5)/ purple is the least likely.

A function is shown
f(x)=2/3x+3 what is the value of f(12)
Answer:
11
Step-by-step explanation:
f(12) = 2/3x+3
So, replace x with 12.
2/3(12) + 3
2/3 x 12 = 8
8 + 3 = 11
Find the area of the composite figure?
Answer:
128
Step-by-step explanation:
Let's start by figuring out the last side of the triangle
we can use the pathagoryous theroem and get
11.9²+x²=16.9²
Solve this and get x=12
Let's now compute the area of the triangle
b*h*.5
12*11.9*.5=71.4
So 71.4 is the area of the triangle
we now need to find the area of the semi circle.
to do this we are going to find the area and then divide it by 2
We know that the length is equal to 12 which means that the radius is 6
so we have
π6²/2
which is 56.55
We add the 71.4+56.55= 127.94 which rounds to 128
Answer:
212.758
Step-by-step explanation:
Find the semi-circle first, the diameter is 16.9 ft.
To find area:
Formula:
pi x radius x radius x 1/2
16.9 ÷ 2 = 8.45 (radius)
22/7 x 8.45 x 8.45 = 224.407 (Circle)
224.407 ÷ 2 = 112.203 (Semi circle)
Find the triangle:
1/2 x base x height or length x base x height
But for now, we will use the first one.
1/2 x 16.9 x 11.9 = 100.555
Now add them up.
100.555 + 112.203 = 212.758
