You can solve this question with pythagorean theorem > {a}^{2} + {b}^{2} = c^{2}

Based on the information, you already have one side (a or b, doesn't matter, 12) and the hypotenuse (the cut, c, 15)

So: 
1. 12^{2} + b^{2} = 15^{2}
2. 144+b^{2} = 225
3. b^{2} = 225 - 144 = 81
4. b=  \sqrt{81}
5. b=9

You deposit $1,000 in the bank and leave it for five years at 3 percent annual interest, making no additional transactions on th
svetlana [45]

Answer: you would withdraw $1150

Step-by-step explanation:

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

Where

I represents interest paid on the amount deposited.

P represents the principal or amount deposited.

R represents interest rate

T represents the duration in years.

From the information given,

P = 1000

R = 3%

T = 5 years

I = (1000 × 3 × 5)/100 = $150

The amount that you would withdraw including principal and interest would be

1000 + 150 = $1150

2. Samuel used clay to make a diorama of the pyramids in Ancient Egypt. He made two triangular pyramids and three rectangular py
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

Find the area of the regular hexagon
earnstyle [38]

Answer:

Area = 166cm² (Approximately)

Step-by-step explanation:

To solve this, let's recall the formula for the area of a REGULAR Hexagon.

The area of a REGULAR Hexagon is expressed as:

A = (3√3 * a²) / 2

Where a is the length of one side of the Hexagon.

a= 8cm.

Area = (3√3 * 8²) / 2

Area = (3√3 * 64) / 2

Area = (192√3) / 2

Area = 332.55 / 2

Area = 166.28cm²

Area = 166cm² (Approximately)
