Find the approximate volume of this prism.

Mathematics
1 answer:
musickatia [10]3 years ago

Answer:

62m³

Step-by-step explanation:

The question is incomplete. Find the diagram of the prism attached below.

Volume of a Prism = Base area × Height

Given height = 9m

Since the prism is a triangular based prism,

Base area = area of the equilateral triangle = 1/2bh

base of the triangle = 4m

Height can be gotten using Pythagoras theorem.

Slant side of the triangle is the hypotenuse = 4m

Adjacent = 1/2 of the base = 1/2(4)= 2m

Height = √4²-2²

Height = √16-4

Height of the triangle= √12 m

Base Area = 1/2×4×√12

Base Area = 2√12 m

Volume of the prism = 2√12 × 9

= 2×2√3×9

= 36√3 m³

= 62.2m³

Volume of the prism is approximately 62m³

The time required to do a job varies inversely as the number of people working. It takes 5hr for 7 bricklayers to build a park w
ExtremeBDS [4]

<u>Answer</u>

3.5 hours.


<u>Explanation</u>

The first step is to calculate the constant of proportionality.

t ∝ 1/n

t = k/n   Where t = time, K= constant and n = number of people

t = k/n

k =tn

   = 5×7 = 35

The equation becomes;

t = 35/n

for n = 10,

t = 35/10

  t = 3.5 hours.

Rachel's learning to play the violin Monday through Friday she practices 45 minutes on each day on Saturday and Sundays he broug
I am Lyosha [343]

Rachel spends 6 hours 45 minutes a week trying to learn to play the violin.

Step-by-step explanation:

Step 1; Rachel learns for 45 minutes a day from Monday through Friday and in the weekend she learns to play the violin for one and a half hours. So she learns for the following periods of time

Monday - 45 minutes

Tuesday - 45 minutes

Wednesday - 45 minutes

Thursday - 45 minutes

Friday - 45 minutes

Saturday - 90 minutes (60 × 1.5 hours)

Sunday - 90 minutes (60 × 1.5 hours)

Step 2; To determine how much time she practices in a week we just add the individual times she plays on each day.

Total time practices in a week = 45 + 45 + 45 + 45 + 45 + 90 + 90 = 405 minutes = 6 hours 45 minutes.
