Find the surface area of the square pyramid shown. Label the net to help you.I have to show work

Answers

Answer: 40 inches squared

Labels are in the pictures

Step-by-step explanation:

To find the surface area, find the area of each side.

Square (base) : side * side = 4*4 = 16

Triangle (sides) : (base * height)/2

Assuming each side is a isosceles triangle, the base 4/2 = 2

(2*6)/2 = 12/2 = 6

Since there are 4 triangles, we can multiply 6 by 4 to get the combined area. We then add the area of the square to get the final result.

6*4 + 16 = 24+16 = 40

A) Mary read 3 times the amount of books as Carey over the summer. Carey read twice as
many books as Barry. If the students read 405 books combined, how many more books did
Mary read than Barry?
----


Answers

Answer:

225

Step-by-step explanation:

Mary = 3x (3 times Carey)

Carey = x

Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)

3x + x + x/2 = 405

4x + x/2 = 405

8x/2 + x/2 (treat these as fractions) = 405

9x/2 = 405

9x = 810 (cross multiply)

x = 90

Mary = 3(90)      270

Carey =              90

Barry = 90/2      45

Mary - Barry

270 - 45 = 225

Hope this helps! :)

In triangle JKL, < K Measures 50 and < J is congruent to

Answers

The angle measures of J and L are given as follows:

m < J = m < L = 65º.

How to obtain the angle measures?

To obtain the angle measures, we must considering that the sum of the measures of the internal angles of a triangle is of 180º.

The internal angles for this problem are given as follows:

<J.<K.<L.

Angles J and L are congruent, meaning that they have the same measure, which is obtained as follows:

50 + x + x = 180

2x = 130

x = 65º.

Adrian is throwing a ball into a pail. With 50 attempts, the ball goes into the pail and stays 8 times, goes into the pail and bounces out 6 times, and misses the pail 36 times. If Adrian throws the ball again, what is the probability of each outcome?
Probability the ball goes into the pail and stays =
Probability the ball goes into the pail and bounces out =
Probability the ball misses the pail =

Answers

The probability the ball goes into the pail and stays in is 16%

The probability the ball goes in to the pail and bounces out is 12%

The probability the ball misses the pail is 72%

STEPS:
Divide each number by 50.
36 divided by 50: 0.72
6 divided by 50: 0.12
8 divided by 50: 0.16

Remove the 0’s from the numbers
0.72 -> 72
0.12 -> 12
0.16 -> 16

We want to make sure that all these numbers equal 100 because 100% is 50 in this equation.
12 + 16 + 72 = 100
Because those numbers equal 100, 50 is equal to 100%

Hope this helps!

Answer:

The approximate probability that the ball goes into the pail and stays is 8/50 or 4/25.The approximate probability that the ball goes into the pail and bounces out is 6/50 or 3/25. The approximate probability that the ball misses the pail is 36/50 or 18/25.

Step-by-step explanation:

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed. It is based on the results of an experiment or a simulation. For example, if you toss a coin 10 times and get 7 heads and 3 tails, the experimental probability of getting heads is 7/10 = 0.7. This may not match the theoretical probability of getting heads, which is 1/2 = 0.5, because of random variation or error. The more trials you perform, the closer the experimental probability will get to the theoretical probability.

To find the probability of each outcome, we need to divide the number of times the outcome occurred by the total number of trials. Using the given data, we can calculate the probabilities as follows:

The probability the ball goes into the pail and stays = 8/50 = 0.16 The probability the ball goes into the pail and bounces out = 6/50 = 0.12 The probability the ball misses the pail = 36/50 = 0.72

We can check that these probabilities add up to 1, which means they are valid.

Which of the following is true about the area and perimeter of rectangles? A Two rectangles with the same area must have the same perimeter. B Two rectangles with the same perimeter must have the same area. C Two rectangles with the same perimeter can have different areas. D No two rectangles can have the same area.

Answers

The correct answer is C



A states that two rectangles with the same area must have the same perimeter, but this is false.

Let’s say you have a rectangle that has an area of 12 Sq ft

It could be 4 x 3 or 6 x 2

Given that our perimeter is 2l x 2w = p:

8 + 6 = 14 but 12 + 4 = 16



B says that’s two rectangles with the same perimeter must have the same area, this is also false.

Let’s take our perimeter of 16 for example.

We could have a rectangle of 2 x 6 and we could have a rectangle of 4 x 4

However, 2 x 6 has an area of 12
Meanwhile, 4 x 4 has an area of 16



C says that two rectangles with the same perimeter can have different areas. I already proved this with the last one


D says that no two rectangles can have the same area

4 x 3 and 6 x 2 both have an area of 12
