Samuel used clay to make a diorama of the pyramids in Ancient Egypt. He made two triangular pyramids and three rectangular pyramids. How much clay did he use to create all the pyramids

Answers

Answer 1

Answer:

124.16 cubic meter of clay will be used to create all the pyramids

Solution

The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.

For Rectangular Pyramid,

Volume of three rectangular pyramids

3 * BH/3 = BH

Substituting the given values in above equation, we get -

15.5 * 5 = 77.5 cubic centimeter

For triangular Pyramid,

Volume of two  triangular pyramids

2 * BH/3

2* 10 * 7/ 3

46.67 cubic centimeter

Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid = 77.7 + 46.67 = 124.16 Cubic centimeter

the maximum load of elevator is 480 pounds. Assuming that the average mass of student is 45 pounds, and m represents the number of students in the elevator, how many students can take the elevator at the same time

Answers

we can use the equation 45m < 481

we can replace m to see where it caps.

and the cap is 10.

we can replace m to check our work

45(10) < 481

450 < 481

if you add another student, it would go over the limit.

hope this helps :D

The circumference of a circle is 100.48 inches. What is the circle's diameter? Use 3.14 for ​.



pleaseeeeeeeee say me now please

Answers

Answer:

d = 32 inches

Step-by-step explanation:

C = 2 × 3.14 × r

100.48 = 2 × 3.14 × r

Now divide 100.48 by 2 and 3.14 to get the radius:

r = 16 inches

The radius is half of the diameter, so...

d = 32 inches

If b/a = c/b = d/c = 2/3 , then find the value of a:b:c:d.

C. 15 weeks
D. 10 weeks

Answers

Answer:

B. 20 weeks

Step-by-step explanation:

I am using the graphing calculator my school uses for exams. But here is the step by step anyway

5x + 36 = 2x + 96

(5x - 2x) + 36 = (2x - 2x) + 96

3x + 36 = 96

3x  + (36 - 36) = (96 - 36)

3x = 60

(3x ÷ 3) = (60 ÷ 3)

x = 20

x represents weeks

The answer is B 20 weeks

Answer:   25 cartons

========================================================

Explanation:

1 liter = 1000 mL

Note how 1000/200 = 5, which means that if one carton is 200 mL, then five cartons gets us 5*200 = 1000 mL = 1 liter. If it takes five cartons to get 1 liter, then we'll need five times as many cartons to get to 5 liters. So 5*5 = 25 cartons is our goal.

---------

We could also solve like this

(1 carton)/(200 mL) = (x cartons)/(5000 mL)

1/200 = x/5000

1*5000 = 200x .... cross multiply

5000 = 200x

200x = 5000

x = 5000/200 ..... divide both sides by 200

x = 25
