Answer:

Assuming the area is made up of a square and a semicircle.

Perimeter

The side length of the square = 18 ft

We can see 3 full side lengths plus one side length from which we need to subtract 12 ft (see attached diagram).

⇒ perimeter of the square = (3 x 18) + (18 - 12)

                                                          = 54 + 6

                                                          = 60 ft

Circumference of a circle = [tex]\pi[/tex]d (where d is the diameter)

⇒ arc length of the semicircle = 1/2 circumference

                                                  = 1/2 · [tex]\pi[/tex] · 12

                                                  = 6[tex]\pi[/tex] ft

Total perimeter = 60 + 6[tex]\pi[/tex] = 78.8 ft (nearest tenth)

Area

Area of a square = s² (where s is the side length)

⇒ area of square = 18²

                             = 324 ft²

Diameter = 2r  ⇒  r = 1/2 diameter

Area of a circle = [tex]\pi[/tex]r²  (where r is the radius)

⇒ area of the semicircle = 1/2 · [tex]\pi[/tex] · 6²

                                         = 18[tex]\pi[/tex] ft²

Total area = 324 + 18[tex]\pi[/tex] = 380.5 ft² (nearest tenth)

Answer:

A and infinite solutions

Step-by-step explanation:

4/5x - 8 = 4(1/5x - 2)

4(1/5x - 2)

4/1 x 1/5x = 4/5x

4 x (-2) = -8

Put them together and you get:

4/5x - 8 AND

4/5x - 8 = 4/5x - 8

IF 2 SIDES OF AN EQUATION ARE THE SAME THEN THE ANSWERS ARE INFINITE

YOU CAN TURN THE EQUATION INTO JUST (x = x)

Answer

B and One Solution

Step-by-step explanation:

4/5x - 8 = -(4/5x + 2)

-(4/5x + 2) = -4/5x - 2

ADD 4/5x TO THE BOTH SIDES

8/5x - 8 = -2

ADD 8 TO BOTH SIDES

8/5x = 6

DIVIDE BOTH SIDES BY 8/5 OR 1.6

x = 3.75

Answer:

220.5 sq feet

Step-by-step explanation:

Given : Bev has to cut her grandma's grass this weekend

Six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.

To Find : Area of Polygon

Solution:

Area of triangle = (1/2) bh

= (1/2) * 15 * 15

= 112.5   sq feet

= (1/2) * 4 * 4

=  8   sq feet

Area of rectangle = 25 x 4 = 100   sq feet

Total area =112.5 +  8  + 100

= 220.5 sq feet

Area of Polygon = 220.5 sq feet

Answer:

398 ft²

Step-by-step explanation:

Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.

Triangle area = 1/2·bh

Rectangle area = bh

___

So, the first triangle has an area of ...

1/2·(20 ft)(20 ft) = 200 ft²

The second triangle has an area of ...

1/2·(6 ft)(6 ft) = 18 ft²

The rectangle has an area of ...

(30 ft)(6 ft) = 180 ft²

And the area total is ...

200 ft² +18 ft² +180 ft² = 398 ft²

i used a calculator

Answer:

I think it's the 2nd choice. Hopefully I got this correct :)

Step-by-step explanation:

I think you wrote that z will represent the number of hours spent babysitting but I think you meant x.

It's the 2nd choice because $30 is the flat rate for Julia and $10 is the flat rate for Kelsey. Julia has a rate of $5 per hour so that will be the number with the x. And Kelsey has a rate of $15 per hour so that will be the number with the x.

Julia: y = 5x + 30

Kelsey: y = 15x + 10.

How to calculate tax and earning

Given the following paramiters

Total amount earned by the student = $15000

Assume we have the following parameters

Earning paid off in taxes = $1500

Amount spent on living expenses = $3000

Amount she will have left = 15000 - (1500 + 3000)

Amount she will have left = 15,000 - 4500

Amount she will have left = 10,500

Hence the amount she will have left is $10,500

Answer:

$7,500

Step-by-step explanation:

First, find the amount he pays in taxes:

$15,000 x 0.1 = $1,500

Next, find the amount he pays in living expenses:

$15,000 x 0.4 = $6,000

Add the two amounts together:

$1,500 + $6,000 = $7,500

Subtract the combined amount from the original amount to find how much the student saved:

$15,000 - $7,500 = $7,500

Therefore, the college student saves $7,500.

The amount of water in Glass B to equal to 3 times of the amount water in Glass A

The volume is a measurement of three-dimensional space that is utilized.

Let r be the radius and h be the height of the cylinder and cone. Then the volume of the cylinder will be given as,

Volume of A = π r²h cubic units                       ...1

And the volume of the cone will be given as,

Volume of B = (1/3) × r²h cubic units       ...2

From equations 1 and 2

Volume of B = 3 x volume of A

The amount of water in Glass B to equal to 3 times of the amount water in Glass A

Answer:

x = 37°

x = 40°

x = 260°

Step-by-step explanation:

To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.

Question 1

[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]

Question 2

To find the bigger arc, subtract the smaller arc from 360°

⇒ 360° - 140° = 220°

[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]

Question 3

The smaller arc can also be found by subtracting the external angle from 180°

Smaller arc = 180° - 80° = 100°

[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]

[tex]160^{\circ}=x-100^{\circ}[/tex]

[tex]x=260^{\circ}[/tex]

#1

#2

Bigger Arc=360-140=220°

#3

Smaller arc=180-80=100°

Answer:

The formula that is used to determine the volume of the cylinder in terms of pi is V = πr2h cubic units where, "V", "r" and "h" are the volume, radius, and height of the cylinder. This formula of volume of the cylinder also shows its dependence on the radius and height of the cylinder.

Answer:

[tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex]

Step-by-step explanation:

y= mx +c, where m is the slope and c is the y-intercept.

We need to find the value of m and c, which can be done by using the slope formula and by substituting a pair of coordinates respectively. Find m first before finding the value of c.

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

[tex]slope = \frac{7 - ( - 4)}{5 - ( - 8)} [/tex]

[tex]slope = \frac{7 + 4}{5 + 8} [/tex]

[tex]slope = \frac{11}{13} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{11}{13} x + c[/tex]

Substitute a pair of coordinates:

When x= 5, y= 7,

[tex]7 = \frac{11}{13} (5) + c[/tex]

[tex]c = 7 - \frac{55}{13} [/tex]

[tex]c = \frac{91}{13} - \frac{55}{13} [/tex]

[tex]c = \frac{36}{13} [/tex]

[tex]c = 2 \frac{10}{13} [/tex]

Thus, the equation of the line is [tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex].
