Answer:

C. Amount needed to fence around a circular garden

Step-by-step explanation:

The Circumference of a circle can be referred to as the length of the circle. It also called the perimeter of a circle.

The circumference of a circle can be defined as the distance roundabout a circle.

The circumference of a circle is calculated mathematically as:

a) 2πr or

b) πD

Where r = radius of the circle.

D = Diameter of the circle

Answer:

The angle for each slice is 45 degrees.

Step-by-step explanation:

In order to calculate the angle of each slice, we first need to calculate the total area of the pizza, because we will use that to find the area of each slice and as a result it's angle. To calculate the area of the pizza we must use:

pizza area = pi*r²

r = d / 2 = 14 /2 = 7 inches

pizza area = pi*(7)² = 153.86 square inches

Since the pizza was divided in 8 pieces, the area of each piece is given by the area of the pizza divided by the number of slices. We have:

slice area = pizza area  / 8 = 153.86 / 8 =19.2325 square inches

Each slice is a circle sector, therefore it's area is given by:

slice area = (angle*pi*r²)/360

Therefore we can solve for angle:

19.2325 = (angle*pi*7²)/360

angle*pi*49 = 6923.7

angle = 6923.7 / pi*49 = 45 degrees

The angle for each slice is 45 degrees.

Answer: 4y -12

Step-by-step explanation:

Let's take this step-by-step:

[tex]-\frac{2}{7}[/tex](-14y + 42)

Distribute the [tex]-\frac{2}{7}[/tex] to -14y and 42

[tex]-\frac{2}{7}[/tex]  * -14y = 4y

[tex]-\frac{2}{7}[/tex] * 42 = -12

We get

4y + (-12)

Simplify this to get:

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh

A = 1/2 (4)*8

A = 16

Answer:

The area of the triangle is 16 cubic units

Step-by-step explanation:

The formula for the area of a triangle is like the same as a rectangle, just in half.  So, by doing 8x4, you get 32.  Divide 32 by 2 to get 16.

Answer:

7x - 3y = -34

7x - 3(2) = -34

7x - 6 = -34

7x - 6 + 6 = -34 + 6

7x = -28

7x/7 = -28/7

x = -4

7(-4) - 3y = -34

-28 - 3y = -34

-28 + 28 - 3y = -34 + 28

-3y = -6

-3y/-3 = -6/-3

y = 2

Answer:

His usual speed is 105 km/hr.

Step-by-step explanation:

Let his usually speed be s km/hr and the distance between the towns be d km. So we have the equations:

s =  d/6

s - 15 = d / (6 + 1)

from the first equation:

d = 6s and from the second:

d = 7(s - 15)

Eliminating d we get:

6s = 7(s - 15)

7s -  105 = 6s

s = 105.

Answer:

f(x)=2x

Step-by-step explanation:

You can get your (a)term by finding rise/run, and there is no y-intercept so the (b)term is not known. Thus you get f(x)=2x.

The equation of the line is [tex]y = 2 x[/tex]

From the graph, we have the following ordered pairs

(0,0) and (5,10)

The equation of the line is calculated using

[tex]y = \frac{y_2 -y_1}{x_2 -x_1} \times (x -x_1) + y_1[/tex]

So, we have:

[tex]y = \frac{10 - 0}{5 - 0} \times (x -0) + 0[/tex]

[tex]y = \frac{10}{5} \times (x -0)[/tex]

[tex]y = 2 \times x[/tex]

Evaluate the product

[tex]y = 2 x[/tex]

Hence, the equation of the line is [tex]y = 2 x[/tex]

Answer:

(D)The first column is labeled x with entries 40, 160, 200. The second column is labeled y with entries 60, 15, 0.

Answer:

r=9

ef=55

Step-by-step explanation:

The value of r in the given parallelogram is 9 and the length of EF is 55 units.

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

Given that, in a parallelogram FCDE sides DC and FE are parallel, and sides FC and ED are parallel. The length of CD is 4r + 19, the length of DE is 8r + 3, and the length of FC is 9r - 6.

Since, we know that,

Opposite side of a parallelogram are parallel and equal, therefore,

FC = DE and DC = FE

Therefore,

8r+3 = 9r-6

r = 9

Therefore,

FE = DC = 4r+19

= 36+19

= 55

Hence, the value of r in the given parallelogram is 9 and the length of EF is 55 units.

Answer:

Asa forgot to floss for 106 days.

Step-by-step explanation:

First of all, we will start by writing out the details we are given clearly.

Length of floss used per day = 18 inches

Original length of floss bought for use = 50 ft = 600 inches

Number of days between March 17th and August 2nd = 138 days

Length of floss left after August 2nd = 2 feet = 24 inches

From this, we can clearly calculate the length of floss used.

This will be original floss length - length of floss remaining = 600 - 24 = 576 inches

Length of floss used = 576 inches

If Asa used 18 inches per day, we can find the number of days he flossed by  dividing the length used in total by the length used per day.

That will be 576/18 = 32 days

if Asa flossed for only 32 days, the number of days he didn't floss is 138 - 32 =106 days

Hence, Asa didn't floss for 106 days.

Answer:

5.52 or less

Step-by-step explanation:

The total cost must be less than or  equal to the budget amount

Total cost limit  ≥ fee + cost per ticket * number of tickets

542.94 ≥  45.82 + cost per ticket * 90

Subtract 45.82 from each side

542.94 - 45.82≥  45.82 -45.82+ cost per ticket * 90

497.12 ≥ cost per ticket * 90

Divide each side by 90

497.12≥cost per ticket * 90

497.12/90≥  cost per ticket * 90/90

5.52 ≥  cost per ticket
