Find the radius of a circle with circumference of 45.84 meters. Use 3.14

alukav5142 [94]

Answer:

3.8 meters

Step-by-step explanation:

In order to find the circumference for a circle, we use the formula π(radius)²

The circumference give is 45.84 and the π given is 3.14

All we have to do is to just substitute them.

45.84 = 3.14(radius)²

45.84 / 3.14 = radius²

14.6 = radius²

radius = √14.6

radius = 3.82 ≅ 3.8

6 children and 2 adults are going to the circus. Children tickets are on sale,half price of adult tickets totaling $54. How much

Anon25 [30]

Answer:

Price of 1 adult ticket is $10.8 and Price of 1 children ticket is $5.4.

Step-by-step explanation:

Given:

Number of adults = 2

Number of Children = 6

Total Amount of tickets sold = $54.

We need to find the price of one children's ticket and one adult ticket.

Solution:

Let the Cost of 1 adult ticket be 'x'.

Now Given:

Children tickets are on sale,half price of adult tickets.

Cost of 1 Children ticket = $\frac{1}{2}x$

Total Amount is equal to Number of adults multiplied by Cost of adult ticket plus Number of Children multiplied by Cost of Children ticket.

Framing in equation for we get;

$2x+\frac{1}{2}x\times 6=54\\\\2x+3x=54\\\\5x=54\\\\x=\frac{54}{5} = \$10.8$

Cost of 1 adult ticket = $10.8

Cost of 1 children ticket = $\frac{x}{2}=\frac{10.8}{2} = \$5.4$

Hence Price of 1 adult ticket is $10.8 and Price of 1 children ticket is $5.4.

You are using 0.05 gallons per mile of a SUV gas tank that holds 16 gallons. y = - 0.05x + 16. (Or, if you wish you may use

asambeis [7]

Here, we just use the following x values and put them into the equation.

y = - 0.05x + 16
y = -0.5(0) + 16
y = 16

y = - 0.05x + 16
y = -0.5(160) + 16
y = -80 + 16
y = -64

y = - 0.05x + 16
y = -0.5(320) + 16
y = - 160 + 16
y = -144

Now, to set up the table, you could list the x values and the y values.

x values :- 0,160, 320
y values:- 16, -64, -144
