Answer:

perimeter = 6x + 15

Step-by-step explanation:

The perimeter of the triangle is the distance around the triangle.

We need to apply our ability to convert word problems in to mathematical expressions.

We were told that the bottom of the triangle is x units.

From the diagram perimeter 4x + 12 + x + 3 + x = 6x + 15

Four times the length of the bottom will be 4x .

12 more than 4 times the bottom will be 4x + 12.

Hence another side of the triangle is 4x + 12.

Finally we were told that the last side is 3 more than the bottom, that will be x + 3.

Answer: For the equation simply substitute 30 in for v and 4 in for s in the equation given, so H=-16t^2+30t+4

Part 2.

If the juggler misses the ball, you wish to know the time that it takes for the ball to travel the four feet from his hand to the ground, so respectively,

4=-16t^2+30t+4 or 0=-16t^2+30t or 0 = -16t+30,

solving for t, t =30/16 seconds or 1.875 seconds

Three cards are randomly selected from a standard 52-card deck, one at a time, with each card re- placed in the deck before the

hammer [34]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Three cards are randomly selected from a standard 52-card deck.

Number of heart cards in a deck = 13

Each card replaced in the deck before the next one is picked.

Probability of first card is heart = $P_{1}=\frac{13}{52}$

After replacement, the probability of second card is heart = $P_{2}=\frac{13}{52}$

after replacement, the probability of third card is heart = $P_{3}=\frac{13}{52}$

P = $\frac{13}{52}$ × $\frac{13}{52}$ × $\frac{13}{52}$

= $\frac{39}{156}$

= $\frac{1}{4}$

The probability of all three cards are hearts is $\frac{1}{4}$
