Answer:

area = 138 m²

Step-by-step explanation:

radius of large circle = 12 m

radius of small circle = 10 m

large circle area = πr² = (3.14)(12²) = 452.16 m²

small circle area = πr² = (3.14)(10²) =314 m²

452.16 - 314 = 138.16 m²

Yesterday, 64% of the 6th grade students chose to drink chocolate milk with their lunch. What fraction of 6th grade students Did

Talja [164]

Answer:

$\frac{9}{25}$

Step-by-step explanation:

First subtract 100 and 64. To find how many didn't choose to drink chocolate milk.

100-64=36

Percentages put into fractions will be Percentage over 100.

So, the fraction will be $\frac{36}{100}$ . Now simplify.

$\frac{36}{100}=\frac{18}{50} =\frac{9}{25}$

The diagram below shows several parking spots near the grocery store, formed with three parallel line segments and a transversal

Marina CMI [18]

Something I noticed about angle 4, is that it shares a straight line with angle 3. (above it is a straight line)

A straight line equals 180 degrees.

So, angle 4 + angle 3= 180 degrees.

Angle 3 is congruent to angle 7.

180-132= Angle 7

180-132= 48

48 degrees is your answer.

I hope this helps!
