Answer:

402.1 in^2

Step-by-step explanation:

Find the area of the circle with the 18 in. radius first.

Formula for a circle is πr^2

So the area of the circle with the 8 in. radius is 1017.9 in^2

Now do the same for the 14 in. radius circle.

The area for the 14 in. radius circle is 615.8

Now subtract:

1017.9 - 615.8 =

402.1 in^2

hope this helped!

Which equation represents a line with a slope of -2/3 that passes through point (5, -2)?
serg [7]

Answer:

c) 2x + 3y = 4

Step-by-step explanation:

−2 = −⅔[5] + b

−3⅓

1⅓ = b

y = −⅔x + 1⅓

Then convert to Standard Form:

y = −⅔x + 1⅓

+⅔x + ⅔x

__________

⅔x + y = 1⅓ [We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

3[⅔x + y = 1⅓]

2x + 3y = 4

* 1⅓ = 4⁄3

I am joyous to assist you anytime.

Scilla [17]

Answer:

x = 4

Step-by-step explanation:

3 x ( 4x -7 ) = 27

3 x 4x = 12x

3 x -7 = -21

12x -21 = 27

12x -21 + 21 = 27 + 21

12x = 48

12x/12 = 48/12

x = 4

Refer to a standard deck of playing cards. Assume 5 cards are randomly chosen from the deck. How many hands contain 4 aces?
Setler79 [48]

There would be 0.07923 probability to get 4 aces.

<h3>What is probability ?</h3>

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Total number of cards in deck = 52

Total number of aces = 4

When 5 cards are chosen randomly,

The probability to get 4 aces

= 1/52+1/51+1/50+1/49+0

Since, at 5th time there will be no ace remains, so probability would be 0.

= 0.01923+0.01960+0.0200+0.0204

=0.07923
