Answer:

AC = 28

Step-by-step explanation:

ΔADB ≈ ΔDBC

DC / BC = AD / 15

16 / 20 = AD / 15

cross-multiply:

20AD = 240

AD = 12

AD + DC = AC

12 + 16 = AC

28 = AC

Write the equation of each circle. center at (-4, 3), radius 9

Answers

Answer:

(x-h)²+(y-k)²=r²

putting respective value

(x--4)²+(y-3)²=9²

(x+4)²+(y-3)²=81

Answer:

(x + 4)^2 + (y - 3)^2 = 9^2

Step-by-step explanation:

Here our center is at (-4, 3), so h = -4 and k = 3.  Radius, r, is 9.

Insert these values into the standard equation of a circle centered at (h, k) with radius r:

(x - h)^2 + (y - k)^2 = r^2 becomes:

(x + 4)^2 + (y - 3)^2 = 9^2

A squirrel burrowed 12 holes in 3 minutes. How many holes could the squirrel burrow in 12 minutes?

Answers

Answer:

48 holes

Step-by-step explanation:

We know that in 3 minutes, a squirrel managed to bury 12 holes. Now, what if there were 12 minutes?

To solve this, we need to see the increase in minutes and implement the same thing to the holes.

So how do we get 3 minutes to 12 minutes? By multiplying 3 by 4, now do the same for the amount of holes the squirrel burrowed in 3 minutes.

3min * 4 = 12min

12 holes * 4 = 48 holes

25x = $831.25

x = $831.25/25

= 33.25 driveways

Step 2

He can shovel

14 driveways = 8 hours

33.25 driveways = x

Cross Multiply

14x = 8 × 33.25

x = 8 × 33.25/14

x = 19 hours
