deandre downloaded 8 apps onto his tablet in 12 secs at this rate how many apps could he download in one minute
Misha Larkins [42]

Because 1 minute is 60 seconds, and it takes 12 seconds to download 8 apps, the first thing we need to do is find out how many "sets" of 12 seconds can go in 60 seconds:

60 / 12 = 5

Now, all we have to do is multiply the number of apps by 5, and we get our answer:

8 · 5 = 40

So, it would take Deandre 1 minute to download 40 apps.

Change general form of hyperbola into standard: -x^2 + y^2 -16x + 14y - 251 = 0
topjm [15]

Answer:

(y+7)²/364 - (x+8)²/364 = 1

Step-by-step explanation:

This is the standard form of a vertical hyperbola (y-k)²/a² - (x-h)²/b² = 1

so, (y²+14y+?) - (x²+16x+?) = 251

(y²+14+49)-49 - (x²+16x+64)-64 = 251

(y+7)² - (x+8)² = 251 + 49 + 64

(y+7)² - (x+8)² = 364

(y+7)²/364 - (x+8)²/364 = 1
