zalisa [80]

Answer:

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

Step-by-step explanation:

The remaining part of the question is given in the attached file

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 * \frac{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 * \frac{BH}{3}\\2 * \frac{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

What is the resulting balance of $3,500 at 4% compounded annually for 8 years?
Brrunno [24]

Answer:

<h3>$4,789.99</h3>

Step-by-step explanation:

Using the formula for calculating the compound interest

A = P(1+r)^t

P is the principal = $3500

r is the rate = 4% = 0.04

T is the time = 8 years

Substitute

A = 3500(1+0.04)^8

A = 3500(1.04)^8

A = 3500(1.3686)

A = 4,789.99

Hence the resulting balance is $4,789.99
