Answer:

Step-by-step explanation:

Maddie = y

Ryan = x

One more than means to (add 1)

Three times means to (multiply by 3)

Maddie worked for y hours

Ryan worked for

* x hours

* three times the number of hours that Maddie did

x = 3y

one more than

x = 3y + 1

Altogether

x + y = 45 hours

(3y +1) + y = 45

3y + y = 45-1

4y = 44

y= 44/4

y =11

Ryan hours (x)

x = 3y + 1

x= 3(11) + 1

x =33+ 1

x=34

Maddie hours (y)

y=11

x + y= 45

34+11= 45

Ryan: 34 hours

Maddie: 11 hours

when a spherical balloon is filled with air, it has a radius of 3 inches. what is the estimate for the volume of air in the ball
Crazy boy [7]

The volume of a sphere is given by the equation V=\frac{4}{3} \pi r^{3}, where V is the volume and r is the radius.


To answer this question, simply plug the correct values into the equation:

V=\frac{4}{3} \pi 3^{3} \\V=4.1888(27)\\V=113.0976


The volume of the air in the balloon is about 113.0976 in3.


Hope this helps!!

What's the correct formula for this function? ​
Reptile [31]

Answer:

Option C. y = -2x + 3

Step-by-step explanation:

When we look at this function we see that it has a negative slope and the y-intercept is equal to (0,3).  From this we know that the function we are looking for will be looking like...

y = mx + 3

And as I said earlier since the slope is negative, the only right option is this case will be Option C
