Answer:

30 minutes

Step-by-step explanation:

We can use ratios to solve

2 miles 5 miles

------------ = -------------

12 minutes x minutes

Using cross products

2 *x = 12*5

2x = 60

Divide by 2

2x/2 = 60/2

x = 30 minutes

blagie [28]

Answer:

Hi there!

Your answer is: 150 people prefer that school assemblies be held on Friday afternoon

Step-by-step explanation:

3 out of 4 students means that 75% of students prefer assemblies on Friday afternoon!

To find 75% of 200:

200 = 100%

/100 to find 1%

2 people = 1%

Multiply it by 75 to determine 75%

2×75= 150

150people is 75% of 200 people!

I hope this makes sense! Let me know if you have questions!

Find the area of an octagon whose perimeter is 120 cm.

stira [4]

Answer:

The area of an octagon whose perimeter is 120 cm is 1086.4 $cm^{2}$

Step-by-step explanation:

An octagon is a polygon with eight sides. If the lengths of all the sides and the measurement of all the angles are equal, the octagon is called a regular octagon.

There is a predefined set of formulas for the calculation of perimeter, and area of a regular octagon.

The perimeter of an Octagon is given by

$P=8a$

and the area of an Octagon is given by

$A=2a^{2}(1+\sqrt{2})$

We know that the perimeter is 120 cm, solving for side length (a) in the perimeter formula we get

$120=8a\\\frac{8a}{8}=\frac{120}{8}\\a=15$

Now, we calculate the area

$A=2a^{2}(1+\sqrt{2})\\A=2(15)^{2}(1+\sqrt{2})\\A=450\left(1+\sqrt{2}\right)\\A\approx 1086.4 \:cm^{2}$
