There are 175 students in 12th grade at silverado high school. a survey shows that 64% of them are planning to attend college. how many students are planning to attend college?

112 students are planning to attend college.

Step-by-step explanation:

Given : There are 175 students in 12th grade at Silverado High School.

A survey shows that 64% of them are planning to attend college.

i.e. proportion of students in 12th grade at Silverado High School are planning to attend college : p=0.64

Now, the number of students are planning to attend college will be :

Hence, 112 students are planning to attend college.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
