3) Stella drove for 300 miles to Washington D. C. and it took her six hours. At the same rate, how long would it take Stella to drive 450
miles? Use the ratio table to find your answer.

1/9

Step-by-step explanation:

First lets remember the equation

Speed = DIstance/Time

Lets figure out the first part, her speed, or rate.

Lets plug in now.

Speed= 300/6

Speed= 50 mph.

Now lets do the second part.

50= 450 x T

Solve the equation by taking 450 to the other side.

we get 50/450=T

Which becomes 1/9 when we simplify.

Hope this is the brainliest answer you come across :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
