7.5, 25, and 14.1

I believe

Answer:

1: 7.5 2: 25 3: 14.2

Step-by-step explanation:

For all of these, you want to use the Pythagorean Theorem, which is a^2+b^2=c^2

1. you would have to plug in 13 for b, and 15 for c, because 15 is the hypotenuse

a^2+13^2=15^2

now, solve for a

a^2+169=225

225-169=56

a^2=56

to undo a squared, you have to take the square root of both sides

sqrt(56) is about 7.5

to check, you would have to plug in 7.5 for a

2. you would start off the same way, but this time we are solving for c

15^2+20^2=c^2

225+400=c^2

625=c^2

take the square root of 625

25 is your answer

if you want to check, plug in 25 for c

3. we are trying to find the hypotenuse again, so we are solving for c

5.1^2+13.2^2=c^2

26.01+174.24=200.25

200.25=c^2

take the square root once again

it is approximately 14.2

if you want to check, plug in 14.2 for c

have a great day!

Suppose that there are 20 numbers in a data set and that they are all different. How many of the values in this data set are between the first quartile and the median?

Answers

Answer:

4

Step-by-step explanation:

Since the first quartile is at 25%, 25% of 20 is 5. The median is the 50% mark of the set, and 50% of 20 is 10. So, there are 4 numbers between the 5th data point and the 10th, which are the 6th,7th,8th, and 9th data points.

The answer for this one is 4

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:

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
