Answer:

D.7/80

Step-by-step explanation:

⇒The question is on probability with replacement

⇒The events taken in this probability are independent of each other

⇒Formulae for combined probability of these events is the product of the probabilities of the event

<u>Given;</u>

6 books for fiction, F=6

7 books for humor, H=7

5 books for play, P=5

2 books for adventure, A=2

<u>Evaluating</u>

n(S)=6+7+5+2=20

P(H)=7/20

P(P)=5/20

P(H ∩ P)=P(H)×P(P)

7/20 × 5/20 =7/80

Sidana [21]
Set up a proportion.

\sf\dfrac{20}{25}=\dfrac{50}{x}

Cross multiply:

\sf1250=20x

Divide 20 to both sides:

\sf~x=62.5

So it will take 62.5 minutes for her to complete the worksheet.

Cameron went into a grocery store and bought 4 apples and 7 mangos, costing a total of $17.75. Gavin went into the same grocery
Mekhanik [1.2K]

Answer:

  • apple: $2.25
  • mango: $1.25

Step-by-step explanation:

Let "a" and "m" represent the cost of an apple and a mango, respectively. Then Cameron's purchase can be represented as ...

  4a +7m = 17.75

Gavin's purchase can be represented as ...

  2a +5m = 10.75

Subtracting the first equation from twice the second gives ...

  2(2a +5m) -(4a +7m) = 2(10.75) -(17.75)

  3m = 3.75

  m = 1.25

Then the price of an apple can be found from the second equation:

  2a +5(1.25) = 10.75

  2a = 4.50 . . . . . . . . . . subtract 6.25

  a = 2.25 . . . . . . . . . . . divide by 2

The price of an apple was $2.25; the price of a mango was $1.25.

For a moving object, the force acting on the object varies directly with the object's scceleration. When a force of 90 N acts on
andrezito [222]

The acceleration if the object when force is 100N is 10 meters per seconds squared

<h3>How to find the acceleration of the object</h3>

Given the direct variation relationship

force , f α acceleration, a

f = ka

k = constant of variation

solving for k

90 = k * 9

k = 90/9

k = 10

when force is 100N

100 = 10 * a

a = 100 / 10

a = 10
