The net of a square pyramid is shown below. What are the possible areas for a single face in this net? Check all that apply.

A net with a square base with sides lengths of 5 meters, and 4 triangles with heights of 6 meters.
11 square meters
15 square meters
24 square meters
25 square meters
30 square meters

Answers

Answer: 1,2,and 4. I did it online and got it right!

Answer:

B. 15 square meters (for the triangles)

D. 25 square meters (for the square base)

Bonus: The total surface area would be 85 square meters.

Step-by-step explanation:

The square base is easier to deduce here; simply square 5 to get 25 square meters for the base.

The triangles require some math, however. But it is relatively simple

(5 * 6)/2

30/2

15 square meters for the triangles.

For bonus, I'll find the total surface area.

5² + 4((5 * 6)/2)

First, square 5 to get 25.

25 + 4((5 * 6)/2)

Now multiply 5 * 6 to get 30.

25 + 4(30/2)

Then divide 30 by 2 to get 15.

25 + 4(15)

Now multiply 4 by 15 to get 60.

25 + 60

Lastly, add 25 and 60 to get 85.

The entire square pyramid's surface area is 85 square meters.

I hope this helps! ヽ(*⌒▽⌒*)ﾉ

HELP PLEASE ! Find the height of the trapezoid

Answers

Answer:

The height is 10.

Step-by-step explanation:

Since the trapezoid is 2 triangles plus a square, we can split it into a rectangle (the two triangles put together) and the square. Let's call the height "x". The trapezoid's area becomes 8x [the square]+2x[the traiangle]. But wait! It states that the area is 70m, so the expression becomes the equation 10x=70m, which is x=10. Therefore, the height is 10.

CAN SOMEONE HELP ME PLEASE???

Answers

Answer:

Step-by-step explanation: First, you need to write all your data down from least to greatest. Next, count up all the numbers to see how many students. Then you want to find the mean which is average (add then divide). Median is the middle so you will x each number out till you get to the middle, and if the middle is 2 numbers, you find the average of them to find the median. Mode means most often. Range is highest minus lowest. And you can do the next 2.

Answer:

Range: 7

Greater than 9 is: 7

I'm not really sure about the distribution

Total Student: 25

Mean: 8.68

Median: 9

3. can't answer a, but b is 1/14 or 7%

4. as a fraction= 1/6

as a percent= 17% (rounded up)

Step-by-step explanation:

2. I just took the outcome needed and decided by the possible outcomes.

3. That was a compound event so I just got the probability of flipping tails (1/2) and multiplied it by the probability of getting a white ball (1/7)

4. another compound event, I got the probability of getting a medium (1/3) and multiplied it by getting yellow (1/2)

Kathy can key in 6 letters every 3 seconds on her phone. How many letters can she type in a minute and a half?

Answers

Kathy can type 180 letters

Answer:

She can type 180 letters in a minute and a half.

Step-by-step explanation:

6 letters per 3 seconds, so we need to find how many letters per 90 seconds, or minute and a half.

6/3 = x/90

Where x represents how many letters she can type in 90 seconds.

2 = x/90

Multiply by 90.

x = 180.
