Answers

Answer:

Step-by-step explanation:

Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

I answered your other question, and I'm feeling lazy, so let me just copy + paste my answer here.

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.

The tires on a compact car are 18 inches in diameter.
a. How far does the car travel after the tires turn once? Use 3.14 as pi
b. How far does the car travel after 12 rotations of the tires? Use 3.14 as pi.

Answers

Answer:

1. 56.52 inches

2. 141,300 inches

Step-by-step explanation:

One turn of the tire is the circumference. Therefore, we have to find the circumference first. C = πd = 18π = 18 × 3.14 = 56.52 in

2500 rotations would be 2500 ⋅ 56.52 in = 141,300 in

Answer ASAP! and whoever gets it right can have brainliest

Answers

Answer: 9

Step-by-step explanation:

the formula for the area of a triangle is a=bh/2, since the area is 54 we would need to multiply it by 2 which would be 108 to reverse the division. then we would divide it by 12 which would be 9 to reverse the multiplication.

Answer:

[tex]beinggreat78~here.[/tex]

The base is 9

Multiply 9 by 12, which is 108, and divide by 12, which is a way of giving you 9.

You toss a coin (heads or tails), then spin a three-color spinner (red, yellow, or blue). Complete the tree diagram, and then use it to find a probability.

1. Label each column of rectangles with "Coin toss" or "Spinner."

2. Write the outcomes inside the rectangles. Use H for heads, T for tails, R for red, Y for yellow, and B for blue.

3. Write the sample space to the right of the tree diagram. For example, write "TY" next to the branch that represents "Toss a tails, spin yellow."

4. How many outcomes are in the event "Toss a tails, spin yellow"? (1 point)

5. What is the probability of tossing tails and spinning yellow? (1 point)

Answers

Answer:

If the spinner has an even number of spaces,

. If the spinner has an odd number of spaces, more information is needed.

Explanation:

The answer depends on whether the spinner has an odd or even number of spaces.

If the spinner has an even number of numbers on it, there will be an equal number of odd and even numbers, meaning that the probability of spinning an odd number is

. This is also the probability of flipping heads on a coin. And so we have:

If the spinner has an odd number of numbers on it, the probability of spinning an odd number will vary. For instance, if there are 3 spaces on the spinner, the probability of spinning an odd number will be

. However, if there are 11 spaces, the probability will be

Step-by-step explanation:

The probability of tossing tails and spinning yellow is 1/6.

What is probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Outcomes of tossing a coin= {T,H}

Outcomes of spinner={ R,Y,B}

Now, outcomes are in the event "Toss a tails, spin yellow"

= {TY}

probability of tossing tails and spinning yellow,

= 1/2*1/3

= 1/6

Answers

Answer:

102º

Step-by-step explanation:

So you know that ABC is an Isosceles triangle as AB=AC therefore, angle ABC is equal to angle ACB.

You also know that even though it doesn't look like it, ABP is an equilateral triangle as AB, AP and BP are equal so all those angles must equal 60º.

So:

ABC = 60 - 21 = 39º

and since ABC= ACB

ACB also equals 39º.

Because angles in a triangle add to 180º, BAC is consequently:

180- (39+39) = 180 - 78 = 102º

BAC = 102º

102 degrees because of the angles and lines

In your own words describe how you would find the volume of a
figure using unit cubes?

pls answer today will give brainliest if correct!<3

Answers

You could find the volume of a figure using unit cubes by placing cubes inside the figure until it is full and counting while you are placing them inside. If that is not an option you can find the measure of the figure by using the cubes to count them. Ex. With a wooden letter block you can black the unit cubes on the bottom to find out the length, place the cubes on the side in 1 layer at the bottom to find the width, then stack them up at the edge of a side to find the height. Once you have found these three numbers you can multiply them to find the volume.

Answer:

|x - 5| = 2

Step-by-step explanation:

Since we are not given a zero on the number line, we do the following:

Average = midpoint between two numbers on the number line

For this number line,

Average = 3 + 7 ÷ 2

Average = 5

Next we find how many units away are each number from the middle:

3 is 2 units away from 5

7 is 2 units away from 5

Units away = 2

Let's use the formula:

|x - average| = Units away

Substitute values into equation

|x - 5| = 2

Now we solve

Solve for x over the integers:

|x - 5| = 2

Split the equation into two possible equations:

x - 5 = 2 or x - 5 = -2

Add 5 to both sides:

x = -5 + 5 = 2 + 5 or x - 5 + 5 = -2 + 5

Answer:

x = 7 or x = 3
