Alisha kept track of the growth of a plant. at the beginning of one week, her plant was 1 7/8 inches tall. the next week, the plant was 2 3/4 inches tall. how many inches did Alisha's plant grow over the week?

Step-by-step explanation:

first week = 1 7/8

second week = 2 3/4

difference is height = 2 3/4 - 1 7/8

note: 2 3/4 = 1 7/4 so,

= 1 7/4 - 1 7/8

subtract whole number: 1 - 1 = 0

combine fractions:  7/4 - 7/8 = 7/8

= 7/8

Alisha's plant grow over the week:

2 3/4=((4*2)+3)/4=11/4

1 7/8=((8*1)+7)/8=15/8

so

2 3/4 - 1 7/8=11/4-15/8=(2*11-15)/8=7/8

so Alisha's plant grow over the week 7/8 inches

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

d. all of the above
