Sarah had 25 candies. Sarah gave 25 of the candies to her sister. Of the amount left, she gave 2/3 to her friend. How many candi
RoseWind [281]

Answer:

She has 5 candles left.

Step-by-step explanation:

Total of candy Sarah has = 25candies

If Sarah gave 2/5 of the candies to her sister, the total amount she gave her sister will be 2/5 of 25

2/5 of 25 = 10

The remaining candy left will be 25-10 which is 15.

If she gave 2/3 of the amount left to her friend, the amount she gave her friend will be 2/3×15 = 10candies.

The height of a volleyball, h, in feet, is given by h = −16t^2 + 11t + 5.5, where t is the number of seconds after it has been h
faust18 [17]

Answer:

The volleyball travel high enough to clear the top of the net.

Step-by-step explanation:

The height of a volleyball, h, in feet, is given by h = −16t² + 11t + 5.5, where t is the number of seconds after it has been hit by a player.

Now, for h = 7.3 feet, we can write

7.3 = - 16t² + 11t + 5.5

⇒ 16t² - 11y + 1.8 = 0

Using the quadratic formula we get,

t = \frac{- (- 11) \pm \sqrt{(-11)^{2} - 4(16)(1.8)}}{2(16)}

⇒ t = \frac{11 \pm 2.4}{32}

⇒ t = 0.27 or t = 0.42

Therefore, for the two real positive values of t the volleyball travel high enough to clear the top of the net. (Answer)

Tpy6a [65]

Answer:

The markup rate is 51% on the cost

Step-by-step explanation:

Price of book = 7.99

Cost to the store = 5.29

The markup rate is a term used to figure what percentage is added on to the cost of the item to find its selling price.

If we subtract cost from the price we will know how much is added to actual cost: 7.99 - 5.29 = 2.7

Markup rate = \frac{added value}{cost}

Markup rate = \frac{2.7}{5.29} = 0.51

Markup rate is 0.51*100 = 51%
