Answer:

circumference of the circle = 10π

Step-by-step explanation:

The radius of the circle is 5 in.

we need to find the   circumference of the circle

circumference of the circle formula = 2 π * r

Where 'r' is the radius of the circle

radius of the circle = 5 in

Plug in 5 for the radius of the circle in the formula

circumference of the circle = 2 π * r =2 π * (5)= 10π

circumference of the circle = 10π

I need help wiith all❤️It’s urgent please
faltersainse [42]

Answer:

1. D

2. D

3. B

Step-by-step explanation:

1. The y-axis of the graph is the volume of gas in the tank and the x-axis is the distance traveled. So the y-intercept represents how much gas is in the tank before it has been driven anywhere. D

2. Just by inspecting the graph, we can see that the x-intercept is 240. So answers a and c are denitely incorrect. Also, since we know the graph is comparing the distance from the house to time, we can observe that the x-intercept is when the cyclist is at home or 0 miles from their house. So the x-intercept must represent the duration of time it took the cyclist to reach home. D

3. Ok so we know the equation of the line is 3x-8y-12=0, and we're trying to find the x and y intercepts. So we can plug 0 in for x to find the y-intercept. And plug 0 in for y to find the x-intercept.

x-intercept: y=0

3x-8(0)-12=0

3x-12=0

3x=12

x=4

=> (4,0)

y-intercept: x=0

3(0)-8y-12=0

-8y-12=0

-8y=12

y=-3/2

=> (0,-1.5)

So the answer is B

4. We can see that one prize is worth $6, so in theory, if the relation was linear we should be able to say that the cost of the number of prizes you buy is 6 times the number of prizes bought. Since we can see that that is not true, we can determine that the data is non-linear. We can also tell that the data is discrete because you can't buy a partial prize. So the answer is C

I'm sorry I don't have time to finish the rest of the questions!! I hope my other answers are helpful though!

Pls help find x in both
RUDIKE [14]

Answer:

Step-by-step explanation:

In similar triangles, corresponding sides are in same ratio

\frac{28}{24} = \frac{3x-9}{x +8}\\\\\frac{7}{6}=\frac{3x-9}{x+8}\\

Cross multiply,

7*(x + 8) = 6*(3x -9 )

7x + 7*8 = 6*3x - 6*9

7x +  56   = 18x - 54

          56 = 18x - 7x -54

          56 = 11x - 54

         11x - 54 = 56

               11x  = 56 +54

                11x = 110

               x = 110 /11

x = 10

PR = 3x -9

     = 30 - 9

PR = 21

ABC and AED are straight lines. BE and CD are parallel. AC = 12.3cm AB = 8.2cm BE = 3.8cm a) Work out length CD. AD = 9.15cm
elena-14-01-66 [18.8K]

Answer:

15.33cm

Step-by-step explanation:

when you try to draw out this figure, satisfying the fact that Ad and Ac are both straight lines. you find the ultimately  it forms a right-angled triangle with sides AC and AD and hypotenuse CD.

Now, you may use Pythagoras theorem to solve:

AC^2 + AD^2 = CD^2

12.3^2 + 9.15^2 = CD^2

CD^2 = 235.0125

CD = square root of 235.0125 = 15.33cm

Hope this helps
