Guo Qi watches 151515 videos on Khan Academy every day. Each video is 888 minutes long on average. For how many days does Guo Qi

lozanna [386]

Answer:

Guo Qi requires 75 days to watch videos on Khan Academy.

Step-by-step explanation:

We are given the following in the question:

Number of videos watched by Guo Qi each day = 15

Average length of each video = 8 minutes

Total minutes of video = 9000 minutes

Total number of videos to be watched =

$=\dfrac{\text{Total minutes}}{\text{Average length of video}}\\\\=\dfrac{9000}{8}=1125$

Guo Qi needs to watch 1125 videos.

Number of days required =

$=\dfrac{\text{Total number of videos}}{\text{Videos watched in one day}}\\\\=\dfrac{1125}{15}=75$

Guo Qi requires 75 days to watch videos on Khan Academy.

Dennis_Churaev [7]

Answer:

x = - 2.5

Step-by-step explanation:

Hi there !

4 - (2x + 4) = 5

4 - 2x - 4 = 5

- 2x = 5

2x = - 5

x = - 5 : 2

x = - 2.5

If the base of a square pyramid is 9 centimeters, and it has a volume of 324 cubic centimeters, what is the height of the pyrami

masha68 [24]

The volume (V) of a pyramid is found using the formula

V = $\frac{1}{3}$ × area of base × height(h)

area of base = 9² = 81 ← area of a square, hence

324 = $\frac{1}{3}$ × 81 × h = 27h ( divide both sides by 27 )

h = $\frac{324}{27}$ = 12 → A
