Answer:

85 units squared

Step-by-step explanation:

By using pythagoras' theroem, you can say a squared + b squared = c squared. If the green shape is a squared and the red is b squared, all you need to do is add the two squares together. The answer wants the answer squared so you just leave the equation answer as it is (85 unit squared) but if the equation didn't want it squared, you would need to square root the answer you it. But for this question, the answer is 85 units squared

Answer:

85 units²

Step-by-step explanation:

All sides of a square are equal.

Area of a square = x · x = x², where x = length of a side

Length of a side of the purple square = √35 = 5.92

Length of a side of the green square = √50 = 7.07

Now you can use the Pythagorean Theorem to find the length, x, of a side of the blue square.

x² = 5.92² + 7.07² = 35 + 50 = 85

x = √85 = 9.2

Therefore, area of the blue square = x² = 9.2² = 85

Step-by-step explanation:

You would need to find a common GCF between them all and 1 is the only GCF that is not fractional. 10/3 and 4/3 are not whole numbers and 3 divided by 10,4, 2, or 5 won't work.

Answer:

D (Alicia did 5 more jumping jacks per minute than Melissa.)

Step-by-step explanation:

Alicia's rate is 30 jumping jacks per minute. You can use the formula m=(y2-y1)/(x2-x1) to find the slope/rate. The two points in the table you can use are (1,30) and (2,60). You can plug those coordinates into the slope formula. (60-30)/(2-1)=30/1= 30 jumping jacks per minute.  To find the rate of change/slope for Melissa, you can use the same formula m=(y2-y1)/(x2-x1). The two points you could plug in are (0,0), and (4,100). (100-0)/(4-0)=100/4=25. Melissa does 25 jumping jacks per minute.

Answer:

Given:

The track is a square with a half circle on its left and right sides.

The area of the square is 128 square feet.

To find:

The length of the track.

Solution:

Let side length of the square be x.

Area of square is

Taking square root on both sides.

From the given table 127.7 is closed to 128. So,  is 11.3.

Diameter of circle = Side of square = 11.3.

The track has 2 sides of the square and the distance around 1 complete circle(s).

Radius of circle is

Length of the truck is sum of length of square and radii of two circles.

Therefore, the total length of the track is 22.6 feet

Answer:

Area of the sector = \(24\pi ^{2}\)

The perimeter of the sector of the given circle is 32.75 cm.

The perimeter of a sector is given by the sum of the arc length and the two radii that form the sector. To find the perimeter of this sector, we need to find the length of the arc and the two radii.

The area of the sector is given as 120° at the center. We can use this information to find the length of the arc by using the formula for the area of a sector:

                          Area of sector = (angle/360) x πr²

where r is the radius of the circle and angle is the central angle of the sector in degrees.

In this case, we have:

                          120/360 x π x 8² = 33.51 cm² (rounded to two decimal places)

The length of the arc can be found by using the formula:

                          Arc length = (angle/360) x 2πr

In this case, we have:

                          (120/360) x 2π x 8 = 16.75 cm (rounded to two decimal places)

The two radii that form the sector have lengths of 8 cm each.

Therefore, the perimeter of the sector is the sum of the arc length and the two radii:

                          Perimeter = arc length + 2r

                          = 16.75 + 2(8)

                          = 32.75 cm (rounded to two decimal places)

Therefore, the perimeter of the sector is approximately 32.75 cm.

Step-by-step explanation:

To find the answer, we need to do the steps in reverse.

Add 2 to both sides.

3x = 9

In order to isolate the x from the 3, we need to do the inverse operation.

Divide both sides by 3.

Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Step-by-step explanation:

This is the answer that you want

t=9/4

m=1.95

Answer:

t = 2.25 and m . 1.95

Step-by-step explanation:

4t + 3.5 = 12.5

to start, isolate the variable by subtracting 3.5 from both sides

4t = 9

then, divide both sides by 4 to find what t is equal to

t = 2.25

8m - 5.5 = 10.1

isolate the variable by adding 5.5 to both sides

8m = 15.6

then, divide both sides by 8 to find what m is equal to

m = 1.95

Answer:

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.
