A bouncy ball is thrown into the air. The height of the bouncy ball above ground can be represented by the function h(t)= −16t^2+46t+6, where h is the height (in feet) of the ball above the ground, and t is the time (in seconds) that has passed since the ball was thrown. How many seconds will it take the ball to reach the ground
t=3 seconds
Step-by-step explanation:
h(t)=0 gives
[tex]-16t^2+46t+6=0\\\\8t^2-23t-3=0\\8t^2-24t+t-3=0\\8t(t-3)+1(t-3)=0\\(t-3)(8t+1)=0\\t=3,-\frac{1}{8} (rejected)[/tex]

It cost $0.25 to use a dryer at a laundromat for 15 minutes. The expression
0.25m ÷ 15
represents the cost, in dollars, of using a dryer for m minutes. What is the cost to use the dryer for 120 minutes?
[tex]\Large\boxed{\tt Answer:~2 ~dollars}[/tex]
[tex]\tt Step-by-step~explanation:[/tex]
See how many times 15 can go into 120.
[tex]\tt \frac{120}{15} =8[/tex]
If 15 • 8 is 120, then the cost would have to multiply by 8.
[tex]\tt 0.25*8= 2[/tex]
It costs $2.00 to use the dryer for 120 minutes.
We can also use the equation to help. We plug in 120 for m and solve.
[tex]\tt 0.25(20)=30\\30 \div 15 = 2[/tex]
We still end up with the same result: $2.00 for 120 minutes.

Linda rolled two 6-sided number cubes labeled 1–6 fifty times. She rolled a sum of 6 fifteen times. What is the experimental probability of a sum of 6??
Help!!
Answer:
3/10
Step-by-step explanation:
15/50 = x/100
(Cross multiply)
15 x 100 = 1500
1500 / 50 = 30
30/100
(Simplify)
3/10
The experimental probability of a sum of 6 is 30.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
We have,
Linda rolled two 6-sided number cubes labeled 1–6 fifty times.
She rolled sum of 6 fifteen times.
let x be the Experimental Probability then
15/50 = x/100
15x = 1500
x= 1500/ 50
x = 30
Thus, the required value is 30.

Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board.
Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area.
Adam says he knows another way.
Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board.
1. What is the area of the board shown on the scale drawing? Explain how you found the area.
2. How can Adam use the scale factor to find the area of the actual electronics board? Remember, he uses a different method than Jason.

Robin and Evelyn are playing a target game. The object of the game is to get an object as close to the center as possible. Each player’s score is the number of centimeters away from the center. Robin’s mean is 107, and Evelyn’s mean is 138. Compare the means. Explain what this comparison indicates in the context of the data. Who is winning the game? Why?
ANSWER BELOW for 1st one:
Eveyn's Robins
means : 138 means: 107
So Eveyns mean is greater than Robins beacuse 138 is greater than 107
- THXS FOR LOOKING AND ANOTHER ANSWER IF YOU DONT WANT TO USE THE FIRST ONE PLUSE THEY ARE BOTH RIGHT
Answer for 2 one : Evelyn has the greater mean. It indicates that, on average, her objects landed farther away from the center than Robin’s. This difference means that Robin is winning the game.
Answer:
Robin is winning the game and the explanation for the answer is :
Step-by-step explanation:
core represents the number of centimeter each player is away from the center. Given the mean of Robin = 107 and mean of Evelyn = 138
And, as it is mentioned that the player whose object lands more close to the center wins the game.
Evelyn has the greater mean. It indicates that, on average, Evelyn objects landed farther away from the center than Robin's.
Therefore, this difference means that Robin is winning the game.
