Help me on this one pls
Semenov [28]

Answer:  Plan A is less expensive for 50 minutes. About $6 less than Plan B

At 200 minutes, both plans cost $24

Step-by-step explanation:

1.)  Look at the numbers for minutes going across the bottom from left to right. Find 50. Follow the grid line up to where the blue line crosses it. (The blue line is lower than the red line so the cost is less.) Look at the numbers on the cost scale to verify the difference if someone asked. Plan A costs $6. Plab B costs $12 for 50 minutes.

2.) Look at where the Red and Blue lines intersect. That is where the plans cost the same amount of money for the same amount of minutes. Follow the grid line down from that point to find the number of minutes.

Ron and Freddy built structures out of snap cubes. Ron's tower had an 8-inch square base. Freddy had a 6-inch square base. If Ro
Sphinxa [80]

Answer: Ron tower's

Step-by-step explanation:

Given

Ron tower has a base of A_r=8\ in.^2

Freddy tower has a base of A_f=6\ in.^2

Suppose the tower is in the shape of a square prism

The volume of Ron and Freddy tower is 320\ \text{and}\ 180\ in.^3

The volume of a square-based prism is  V=\frac{1}{3}a^2h

\therefore \text{height of Ron tower is}\ h_r=\dfrac{3V}{A_r}\\\\\Rightarrow h_r=\dfrac{3\times 320}{8}=120\ in.

The height of Freddy tower is

\Rightarrow h_f=\dfrac{3V}{A_f}\\\\\Rightarrow h_f=\dfrac{3\times 180}{6}=90\ in.

Thus, the height of Ron's tower is  more than Freddy's tower by 30\ in.

If a car is moving at a speed of 30 miles per hour, how many miles
Ne4ueva [31]

Answer:

90 miles

Step-by-step explanation:

There's more than one way in which to do this.  I have chosen to convert '180 minutes' to '3 hours.'

Since distance = rate times time, we have here:

distance traveled in 180 minutes = (30 mph)(3 hr) = 90 miles
