Because of a problem in the program, the timer in a video player did not begin counting until the video had been playing for sev
777dan777 [17]

Answer:

105 frames

Step-by-step explanation:

Given that:

At 0 seconds, the video had already played 190 frames and there are 25 frames being played per second.

When the time is equal to 3 \dfrac{2}{5}, the number of frames that are already being played is:

= 3 \dfrac{2}{5} \times 25

=  \dfrac{17}{5} \times 25

= 17 × 5

= 85 frames.

But recall that, the frames had already played 190 frames at 0 seconds, then the number of frames that had already been played when the time is equal to 3 \dfrac{2}{5} is;

=(190 - 85) frames

= 105 frames

The farmer needs to buy fertilizer to spread on his garden. The garden is a 20 x 15 rectangle. A bag of fertilizer covers 30 ft.
Ainat [17]

Answer:

10

Step-by-step explanation:

The area of a rectangle is given by A=lw, where l is the length of the rectangle and w is the width of the rectangle. Therefore, the area of a 20 x 15 rectangle is equal to 20\cdot 15=300\:\mathrm{ft^2}.

Since one bag of fertilizer covers 30 square feet, the farmer needs \left \lceil \frac{300}{30}\right \rceil=\boxed{10} bags of fertilizer.

A pennant is shaped like a right triangle with a hypotenuse of 10feet. The length of one side of the pennant is two feet longer
marissa [1.9K]

Answer:

6 ft and 8 ft

Step-by-step explanation:

let x be the length of one leg then (x + 2) is the other leg.

Using Pythagoras' identity in the right triangle, that is

x² + (x + 2)² = 10² ← expand left side and simplify

x² + x² + 4x + 4 = 100 ( subtract 100 from both sides )

2x² + 4x - 96 = 0 ( divide all terms by 2 )

x² + 2x - 48 = 0 ← in standard form

(x + 8)(x - 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 8 = 0 ⇒ x = - 8

x - 6 = 0 ⇒ x = 6

But x > 0 ⇒ x = 6

Thus the 2 sides are 6 ft and x + 2 = 6 + 2 = 8 ft

I NEED HELP NOW ON PROBABILITY PART 1!!!!!
miv72 [106K]
Principle: divide the correct possibilities by the total nr. of possibilities to find the probability.

6. P(green) = 5 / (7+5+6) = 5/18
7. P(red) = 6 / 18 = 1/3
8. P(not green) = P(red | blue) = (6+7)/18 = 13/18

9. P(HH) = 5/25 = 1/5
10. P(HT) = 16/25
11. P(NOT TT) = P(HH | HT) = (5+16)/25 = 21/25
12. P(HH | TT) = (5+4)/25 = 9/25

13. P(5) = 1/6. P(H) = 1/2. P(5 & H) = 1/6*1/2 = 1/12. If you draw all the possibilities, you'll find there are 12. One of them is 5 & Heads.
