Answer:

Approximately 3.8 seconds

Step-by-step explanation:

H(x)=-16x^2+60x+4

We want to find when the ball hits the ground, or where the zeros are

0 =-16x^2+60x+4

Gillian and her friends are playing a card game using a standard deck, but without the aces. In the deck, there are 36 numbered
Nostrana [21]

Answer:

30

Step-by-step explanation:

To find the best prediction for the amount of numbered cards that will be drawn during the game, first find the probability of drawing a numbered card. There are 36 numbered cards and 48 total cards. So, the probability of drawing a numbered card is  or .

Now, multiply the probability by the number of times a card will be drawn from the deck. Since there are 10 rounds and 4 players, a card will be drawn from the deck 10 × 4, or 40, times. So, multiply  by 40.

Therefore, the best prediction for the amount of numbered cards that will be drawn during the game is 30.

blondinia [14]
First, you must change all of this into improper fractions, like shown below.
- \frac{8}{5}\div - \frac{2}{3} =
Now you must change the sign.
- \frac{8}{5}* - \frac{2}{3} =
Then we must reciprocalize 2/3.
- \frac{8}{5}* - \frac{3}{2} =
Now we multiply, to get 2 4/10.
