Answer:

C= 14.14 yd

Step-by-step explanation:

The circumference of a circle is equal to the equation

C = 2πr

Since the diameter is 4.5, the radius is 2.25.

Plug the radius into the equation, and solve.

C=2π(2.25)

C= 6.283185307(2.25)

C= 14.137

C= 14.14 yd

I hope this helps!

(intro) Slope is change in y divided by change in x (axes). Here, the y axis is depth and the x axis is hours. So, the slope is change in depth between any two points, divided by the change in hours between the same points. The slope of this line is half a foot depth divided by 2 hours.
a) So, the slope is 0.5 / 2 = 0.25, or 1/4.
b) The graph shows a constant rate of change because the line is straight (it increases at the same speed. If the line was curving, it would not be a constant rate of change).
c) Yes, because the line has a constant rate of change now.

Dori and Nemo go to Taco Bell for lunch. Dori orders three soft tacos and three double Deckers $11.25. Nemiah pays $10 for four
gavmur [86]

Answer:

Dori:3x+3y=11.25

Nemo:4x+2y=10

Step-by-step explanation:

Let x and y represent tacos and double Deckers respectively.

For three tacos and three double Deckers, Dori pays $11.25

Writing an equation the statement, we obtain

3x+3y=11.25

Also,for four tacos and two double Deckers, Nemo pays $10

This implies

4x+2y=10

2.25k - 20 = 6.5k + 14 please help me solve this step by step asap!
Rom4ik [11]
Answer:

k= -8

Explaining:


Move variable to the left-hand side and change its sign.

2.25k - 6.5k - 20= 6.5k - 6.5k + 14


Since two opposites add up to zero, remove them from the expression.

2.25k - 6.5k - 20= 14

Collect like terms!

-4.25k = 14 + 20

Add the numbers

-4.25k = 35


Divide both sides of the equation by -4.25

So you will get the answer: k= -8
