Answer:
n+4=32
Step-by-step explanation:
The initial number n gets additional 4 students making the new total number of students to be 32. Therefore, this situation can be represented as
n+4=32
To get the actual number of students before the additio, we make n the subject of formula hence
n=32-4
n=28
Therefore, the initial number was 28 and the equation is n+4=32
Since no choices were provided, the equation that can be modified is n+4=32
2*2+4*2(1+1) that is going be your answer
Answer:
He can run 20 ft in 15 seconds
Step-by-step explanation:
we need to change yards to ft
3ft = 1yd
100 yds * 3ft/1yd = 300 ft
distance = rate * time
300 ft = rate * 15 seconds
divide by 15 seconds on both sides
300 ft/15 seconds = rate
20 ft/sec
He can run 20 ft in 15 seconds
Answer:
D
Step-by-step explanation:
7.6/3.8 = 2
The dilation is by scale factor 2.
8/2 = 4
11/2=5.5
Calculate the volume.
Cross section × height
4 × 3.8 × 1/2 × 5.5 = 41.8
The volume of the smaller prism is 41.8 ft³.
