Answer:

This shaded region is consisted of 2 shapes: a right triangle and a semi-circle. To find the overall area, we must first find the are of the 2 shapes and add them together.

Step-by-step explanation:

1. Find the area of the right triangle:

a = 14, b = 2r = 8cm

A1 = ab/2 = 112/2 = 56cm²

2. Find the area of the circle:

r = 4 cm

A2 = πr² = 3.14 × 4² = 50.24cm²

3. Divide the area of the circle to get the area of the semi-circle:

A3 = A2/2 = 50.24/2 = 25.12cm²

4. Add the areas of the right triangle and the semi-circle together:

A1 + A3 = 56 + 25.12 = 81.12cm²

Answer:

A

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AC}{DF}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values

[tex]\frac{45}{x+8}[/tex] = [tex]\frac{30}{25}[/tex] ( cross- multiply )

30(x + 8) = 1125 ( divide both sides by 30 )

x + 8 = 37.5 ( subtract 8 from both sides )

x = 29.5 → A

Step-by-step explanation:

1. isosceles triangle

2.   3x + 15 = 90       x = 25

     x + 25 = 90        x = 65

     x + 55 = 90        x = 35

3. The size for DAB is 84

My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.

Answer:

  A) difference of squares

  B) GCF

  C) trinomials (X method)

Step-by-step explanation:

When a binomial is a difference of squares, factoring using the "difference of squares" method is appropriate.

The first binomial is ...

  (2x)² -5² . . . . . a difference of squares

  = (2x -5)(2x +5)

__

When the binomial is not a difference of squares, but there is a common factor, then the GCF method is appropriate.

  2x³ -4x² = 2x²(x -2) . . . . . GCF method

__

When the expression is a trinomial, often the X method can work for factoring it.

  x²-5x +6 . . . . 2 numbers are needed that sum to -5 and are factors of 6

  6 = (-2)(-3), so the factorization is (by X method)

  (x -2)(x -3)

Answer:

4/11 is already simplified as much as it can be in fraction form. as a percent its 36.3636%

Step-by-step explanation:

The simplified expression of 4/11 is 4/11

From the question, we have the following parameters that can be used in our computation:

4/11

This means that we divide 4 by 11

So, we have the following representation

4/11

In the above, we have

The numerator 4 is less than the denominator 11

This means that the expression is already simplified

Hence, the simplified expression is 4/11

Step-by-step explanation:

y = 28 - 2x

x = 1, y = 28 - 2(1) = 26

x = 3, y = 28 - 2(3) = 22

x = 4, y = 28 - 2(4) = 20

x = 5, y = 28 - 2(5) = 18

Store B has more expensive lawn mowers.

Step-by-step explanation:

The median price is the price in the middle of the possible prices which means that if you double the median price you will get about what the highest price can be.

What can be inferred from the data is store B has more expensive lawn mowers.

Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order. Median is a measure of central tendency.  For example 3 is the median in this dataset: 1, 3, 6

Step-by-step explanation:

Answer:

m = 18

Step-by-step explanation:

In order to solve this we do the following steps:

Multiply both sides by 2 and get...

4 = m - 14

m = 4 + 14

m = 18

Step-by-step explanation:

We have to pay $0.63 sales tax if the rate is 6%.

What is the sales tax?

Sales tax is a tax that is added to the price of goods or services when they are sold. It is typically a percentage of the purchase price and is collected by the seller from the buyer.

In this case, the price of the bucket of popcorn is $8.00 and the price of the soda is $2.50. If the sales tax rate is 6%, the total amount of sales tax paid on the popcorn would be $8.00 x 6/100 = $0.48 and on soda is $2.50 x 6/100 = $0.15. So the total amount of sales tax paid on both items is $0.48 + $0.15 = $0.63

Hence, we have to pay $0.63 sales tax if the rate is 6%.

Answer:

5ft

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Volume = 25π ft cubed

Depth = 3 ft

So, we can calculate the radius by using following formula,

V = 1/3 ×π ×radius squared×depth

25π = 1/3×π×radius squared ×3

Radius squared = 25

Radius = √25

Radius = 5 ft

Hence the radius of the hole is 5 ft.
