AREA OF A CIRCLE HELP PLS​

Answer:

7.5

Step-by-step explanation:

To find the median, first order the numbers from least to greatest:

2, 4, 5, 7, 8, 8, 10, 12

Then, find the middle number (number in the middle):

There are 2 middle numbers. 7 and 8.

Because there are 2 numbers, we need to find the average. If there was only one number, that would be the median.

To find the average, add 7 and 8. Then, divide the sum by 2 because there are 2 numbers;

7 + 8 = 15

15 / 2 = 7.5

Have a nice day!

Answer:

73.4

Step-by-step explanation:

the answer is 73.3966

Step-by-step explanation:

1:4=.25 or 25%

so 12/47=.25 or 25%

24/120=.2 or 20%

that ratio does not match the height ratio

Sarah's scale is reasonable.

A scale drawing is a smaller diagram in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.

The first step is to determine the how larger the paper is in terms of the painting.

48 / 12 = 4

120 / 24 = 5

This makes her scale of 1 in to 4 in reasonable.

Answer:

145

Step-by-step explanation:

Supplementary angles add up to equal 180 degrees

Thus, ∠ABC + ∠DEF = 180°

If ∠ABC = 35

Then 35 + ∠DEF = 180

180 - 35 = 145

Hence, ∠DEF = 145

Answer:

78.5 cm^2

Step-by-step explanation:

the circle's diameter is 10cm --> its radius is 5cm

the area of the circle is 5^2 x 3.14 = 78.5cm^2

The area of circle is [tex]25\pi[/tex] square units.

What is the formula for area of circle?

The area of a circle is given by [tex]\pi r^{2}[/tex] where r is the radius of the circle.

The given circle is inscribed in a square. so, the side length of the square will be the diameter d of the circle.

So, d=10.

Divide diameter d by 2 to get the radius of the circle.

[tex]r=\frac{10}{2}[/tex]

So, r=5.

Substitute 5 for r into the formula of area of circle.

[tex]\pi \cdot5^{2}=25 \pi[/tex]

Therefore, the area of circle is [tex]25\pi[/tex] square units.

Answer:

175 chairs left

not sure

Answer: 175

Step-by-step explanation: 23 times 8 - 9

23 rows with 8 each means you need to find the total amount of chairs you should multiply them and subtract 9.

Strictly increasing functions:

Let a function f(a) for x = a, then,

f(a + h), for x = a + h,

If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.

In the given graph, there are straight lines so you can say increasing interval would have +ve slope.

For x = -5 to -4, it increases = [-5, -4]

For x = 1 to 3, it increases = [1, 3]

Answer: [-5, -4] , [1, 3]

Answer: 54°

Step-by-step explanation:

We can see that this triangle is a right triangle (look at the little square in the triangle's corner-- that tells us that it's a right angle). A right angle is 90°

A triangle always has 180° in total.

So, we can add 90° and 36° and subtract the sum from 180°

180° - (90° + 36°) = 180° - 126° = 54°

Answer:

x = 54

Step-by-step explanation:

One of the properties for any triangle is that the sum of angles in the triangle will always equal 180 degrees. As one can see, one of the angles is (90) degrees, this is indicated by the box around the angle. It is given that one of the other angles is (36) degrees. One can call the unknown angle (x) and form an equation. Substitute in the given values and solve for (x).

(90) + (36) + (x) = 180

Simplify,

126 + x = 180

Inverse operations,

126 + x = 180

-126       -126

x = 54

The answer is 1/4

Step-by-step explanation:

The same number of both heads and tails only appears 4 times in the list of outcomes.

Since there are 16 outcomes in total, 4 out of the 16 (4/16) of the outcomes would have an equal amount of both heads and tails.

Simpify 4/16 to 1/4.

Answer:

87.96 square inches

Step-by-step explanation:

The soup can is a cylinder, and we can find how many square inches the label will take up by finding the lateral surface area

Use the formula, LA = 2[tex]\pi[/tex]rh

The diameter is 4 inches, so the radius is 2 inches

Plug in the radius and height into the formula, and solve:

LA = 2[tex]\pi[/tex]rh

LA = 2[tex]\pi[/tex](2)(7)

LA = 28[tex]\pi[/tex]

= 87.96

So, the label will take up approximately 87.96 square inches

A) First, find the volume of each cube:

V = s³

  = (1/2)³

  = 1/8 ft³

We have a total of 64 cubes, therefore the maximum volume will be:

Vmax = 64 · (1/8) = 8 ft³

B) The volume of a rectangular prism is given by:

V = w × l × h

Therefore any combination of w × l × h = Vmax = 8 will be fine.

Answer:

y = (x - 2)² - 9

Step-by-step explanation:

Using the method of completing the square

add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = x² + 2(- 2)x + 4 - 4 - 5

y = (x - 2)² - 9

Answer:

It actually doesn't matter! The key thing is that the dilation value affects the distance between two points. As in the first example (dilation by a factor of 3), A is originally 1 unit down from P and 2 units to the left of P.

1*3 = 3, so A' (the dilated point) should be 3 units down from P.

2*3 = 6, so A' should be 6 units to the left of P.

It doesn't matter if you go left first or down first, because you always determine the location of A' with respect to P based on the location of A (which doesn't move) with respect to P.
