Answer:

Answer is $\frac{31}{100}$

Step-by-step explanation:

values given in table

Reading books percentage is 22

hence we can write probability as

Probability (reading books) = $\frac{22}{100}$

percentage of surfing internet is= 9

Probability of surfing internet is = $\frac{09}{100}$

the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)

probability (reading or surf)= $\frac{22}{100}$ + $\frac{09}{100}$

= $\frac{31}{100}$

Answer:

31/100

Step-by-step explanation:

From the given table

Reading books percentage is 22

so Probability (reading books) = $\frac{22}{100}$

Surf the internet percentage is 9

Probability (surf the internet) = $\frac{9}{100}$

the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)

probability (reading or surf)= $\frac{22}{100} +\frac{9}{100}$

= $\frac{31}{100}$

A climbing structure needs to be built in the shape of a square-based pyramid. Look at the diagram below. What is the perimeter

Marta_Voda [28]

Answer:

40 m

Step-by-step explanation:

The perimeter of the flat, orange shape is the sum of all the sides that forms a boundary around the shape.

The shape is made up of 4 triangles having 2 equal side lengths each, which surrounds the center square.

Each side length of the triangle, that forms a boundary round the shape = 5 m.

There are 8 of this equal side length.

Perimeter = 8(5m) = 40 m

NNADVOKAT [17]

1.) 9(4) + 8(5)

36 + 40 = 74

2.) 2(3) + 8(3)

6 + 24 = 30

3.) 4(5) + 7(5)

20 + 35 = 55

4.) 10(4) + 18(5)

40 + 90 = 130

5.) 2 + 8(1/4)

2 + 2 = 4

6.) 9(1/3) + 8(1/4)

3 + 2 = 5

7.) 3(8) + 7(4)

24 + 28 = 52

8.) 12(1/4) + 16(5)

4 + 80 = 84

Pete corporation produces bags of peanuts. It's fixed cost is $18,900. Each bag sells for $2.17 with a unit cost of $1.27. What

pentagon [3]

Answer:

in units: 18,900

in dollars: $ 41,013

Step-by-step explanation:

The break even point is the sales dollar amount or sales in unit at whichthe operating income of the firm equals to zero: $\frac{Fixed\:Cost}{Contribution \:Margin} = Break\: Even\: Point_{units }$

Where:

$\frac{Contribution \: Margin}{Sales \: Revenue} = Contribution \: Margin \: Ratio$

Contribution margin:

2.17 - 1.27 = 1 dollar per unit

Break even:

$18,900 fixed cost / $1 per unit = 18,900 units

Then, in sales:

18,900 x $2.17 each = 41.013‬

break even point:

Answer:

2 11/14 squared feet

Step-by-step explanation:

Area of a rectangle = length x width

Give length = 3 1/4 and

Width = 3/4

Therefore,

Area = 3 1/4 x 3/4

Change the mixed size fraction to an improperly fraction

We have A = 13/4 x 3/4
