Step-by-step explanation:

Answer:

The angles of the triangle are 73, 59, and 48

Step-by-step explanation:

The sum of a triangle's angles must always add up to 180

In order to find out the measure of x we must make an equation where 180=the sum of the angles

180=2x+62

We got the 2x and the 62 from combining like terms

x+x=2x

73-11=62

Now we simply use algebra and try to solo out the x

First, subtract 62 from both sides

118=2x

Then, divide both sides by 2

59=x

x=59

Then plug in 59 with x and this gives you

73, 59, and 48 which all together add up to 180

Yes because it is the brainliest answer

Answer:

No

Because you need to half the diameter to fit it into the formula. So you would do 7 divided by 2 to get the radius which is 3.5. Then you do 3.5 x pi

How: The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.

Answer:

D)rotation, reflection

Step-by-step explanation:

Rotation because the figure has rotated in a clockwise direction but since only rotation cannot be the correct answer, the figure has also been reflected after being rotated. Thus only option D is correct.

Answer:

πr + 2r

Step-by-step explanation:

Perimeter of Semicircle

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Step-by-step explanation:

1. d = 22mm

circumference = πr + d

= 22/7 × 11 + 22

= 56.57 mm

2. r = 4 inches

circumference = πr + d

= 22/7 × 4 + 8

= 20.57 Inches

3. d = 10 yards

circumference = πr+d

= 22/7 × 5 + 10

Answer:

[tex]y = 2(x + 3) ^{2} - 1[/tex]

should be it. good luck!

Answer: y = 2 (x+3)^(2) -1

Step-by-step explanation:

y=mx+b formula

inside parentheses as (x+n) or (x-n) brings the graphed line left or right on the x-axis (+ is left, - is right). thus, we have (x+3), which is then squared to create the u shaped curve.

to bring the point curve to a -1 in the y-axis (-3,-1), a -1 is added to the end, outside of the parentheses. thus we now have [(x+3)^2] -1

to narrow the curve, the part parentheses is multiplied, here by two. thus, the final answer is y=[(x+3)^2]-1

The data is dispersed in a box plot with the data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24 is shown in the image attached.

To create a box plot for the given data set:

25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, and 24

One first need to look for some key statistics that will help one make  the plot and they are

So first sort the data in ascending order:

The lines coming out from the box (whiskers) show the smallest and largest values that are within a certain range around the middle of the data. Any data points that are different from the others and fall outside a certain range are called outliers. These outliers are shown separately on a graph.

The box plot shows us how the data is spread out and gives us information about the average value and any very high or very low values.

Answer:

x = -40

Step-by-step explanation:

Rewrite "(x - 4)/4" in a different way:

⇒ 8 + x/2 = (x - 4)/4 - 1

⇒ 8 + x/2 = x/4 - 4/4 - 1

Simplify the R.H.S:

⇒ 8 + x/2 = x/4 - 1 - 1

⇒ 8 + x/2 = x/4 - 2

Add 2 both sides and subtract x/2 both sides:

⇒ 8 + x/2 = x/4 - 2

⇒ 8 + 2 = x/4 - x/2

⇒ 10 = x/4 - 2x/4

Simplify the R.H.S:

⇒ 10 = x/4 - 2x/4

⇒ 10 = -x/4

Use cross multiplication:

⇒ 10 × 4 = -x

⇒ -(40) = x = -40

Answer:

Assuming you meant 11/5 - √(25/4) The answer is -3/10 or -0.3.

Step-by-step explanation:

Subtract the quantities.

The rate of lawn mowing is given as 4/3 lawns per hour.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

The given problem can be solved using unitary method as follows,

The number of lawns mowed in 9 hours = 12

Then, number of lawns mowed in 1 hour = 12/9 = 4/3.

Hence, the rate of mowing lawn for Audrey is 4/3 lawns per hour.

Answer:

  (a) 136 ft

  (b) $680

Step-by-step explanation:

You want to know the perimeter length and the cost of tiling around a pool with the L-shape shown.

The sum of horizontal lengths at the bottom of the pool outline is the same as the length at the top.

The sum of vertical lengths at the left of the pool outline is the same as the length on the right.

The perimeter is the sum of horizontal and vertical lengths of the outline, so is ...

  P = 2(40 ft + 28 ft) = 136 ft

The perimeter of the pool is 136 ft.

The cost of tile is found by multiplying the cost per length by the length around the pool.

  tile cost = ($15/(3 ft))(136 ft) = $680

It will cost $680 to put tiles around the edge of the pool.

Answer:

25

Step-by-step explanation:

(You can do this differently, but I chose to do it like this)

First, convert the 1816 kilograms to pounds.

1816 kilograms = 4003.595 pounds

Then, we can divide 4003.595 pounds by 160 to figure out how many 160-pound people the balcony can hold.

4003.595 ÷ 160 ≈ 25.02

If the balcony holds 26 people, it will collapse, so the answer must be 25.

Circumference of a circle = 2 × π × r

And Diameter = 2 r

Therefore using the formula!

Circumference of the circle with diameter 20 foot :

2 × π × 10 = 20 π foot

Circumference of the circle with diameter 5 foot :

2 × π × 2.5 = 5 π foot

Difference between the sand paintings' diameter = 20 π - 5 π = 15 π foot

Hey there!

When you see or hear the word “accustomed” think of the person/speaker or question telling that it is another name for “Be prepared of something” or just simply think of the word “adaption”.

Another word for “adaption” or “adapt” is “habitation” aka “habitat”

Based on that information I gathered for you, the answer is “in the habit for” (Option C.) because it’s talking about the word “habitat”
