I WILL GIVE BRAINLIST Mark is buying supplies for his students. He is buying a notebook (n) and a pack of pencils for each of his 25 students. Each pack of pencils costs $1.25.

If Mark's total cost is $156.25, which of the following equations can be used to find how much each notebook cost?

Select TWO that apply.

A.

25(n)+31.25=156.25

B.

1.25(n)+25=156.25

C.

25(n)=156.25+31.25

D.

25(n)=156.25−31.25

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
