You randomly select 2 marbles from a mug containing 7 blue marbles, 3 red marbles, and 2 white marbles. How many times greater is the probability of selecting one blue marble and then one red marble when you do not replace the first marble before selecting the second marble than when you do replace the first marble before selecting the second marble? Express the answer as a fraction.

Answers

Answer:

Scenario 1: w/o replacement: P(blue, then red) = (7/12)(3/11) = 7/44

Scenario 2: w/ replacement:  P(blue, then red) = (7/12)(3/12) = 7/48

Ratio of Probability #1 to Probability # 2 = 48/44 = 12/11, i.e. Prob # 1 is 1.0909... times Prob # 2

Pablo bought chocolate bars that were divied into 8 equal pieces. If Pablo has eaten 20 pieces of chocolate, what is the fractionof chocolate bars he has eaten?

Answers

Answer:

Pablo has eaten 2 1/2 chocolate bars.

Step-by-step explanation:

We know that:

- Each bar was divided into 8 equal pieces

- Pablo ate 20 pieces

So, we can find the chocolate bars that he has eaten as follows:

[tex] f = \frac{1 \: bar}{8 \: pieces}*20 \: pieces = 2.5 \: bars = 2\frac{1}{2} \: bars [/tex]    

Hence, Pablo has eaten two and a half of chocolate bars expressed as 2 1/2 as a mixed fraction.

What is the area in square centimeters of the trapezoid below​

Answers

Answer:

area = 1/2(a+b)h

a= 8.2 cm

b= 22.9 cm.

h= 9.8

therefore area = 77.91 sqcm

The area in square centimeters of the trapezoid below​ is 77.91 .

How to find the area of a trapezoid?

The area of a trapezoid is the half of the product of sum of its parallel sides to the height of that trapezoid (the distance between those parallel sides).

Thus, if we have Length of its parallel sides = 'a' and 'b' units respectively

Perpendicular distance between its parallel sides = 'h' units,

Area = 1/2(a+b)h

a= 8.2 cm

b= 22.9 cm.

h= 9.8

Area = 1/2(8.2 + 22.9)9.8

therefore, area = 77.91 sqcm

Given b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C. What is the area of the triangle? Round to the nearest hundredth.

Answers

Answer:

1.73 units

Step-by-step explanation:

The area of a triangle with sides a, b, c and angles A, B, C is given as

Area = 1/2 bc sin A

Given that b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C then the area

= 1/2 * 4 * 1 * sin 120

= 2 sin 120

= 2 * √3/2

= √3

= 1.732

To the nearest hundredth = 1.73

Hello! I’ve been stuck on this problem for a while and—though I know the answer—I’m not sure how to get to it? Please help!

Answers

Answer:

first you will need to break the shape into a semi circle and a triangle.

then solve the area of the semi circle. which is

[tex] \frac{(3.14) \times r ^{2} }{2} \\ [/tex]

[tex] \frac{(3.14) \times 4.6^{2} }{2} \\ = 33.22[/tex]

Then solve the area of the triangle.

First work out the height of the triangle, which is

[tex]13.4 - 4.6 = 8.8[/tex]

then the area. which is

[tex] \frac{1}{2} 4.6 \times 8.8 \\ = 20.24[/tex]

now calc. the two figures. which is

A number is 3 1/3 greater than another. If the sum of the numbers are doubled the answer would be 19 1/2

Answers

Answer:

smaller number = 3 5/24

larger number =  6 13/24

Step-by-step explanation:

let the larger number = x

smaller number = y

x - y = 3 1/3 equation 1

2(x +y) = 191/2 equation 2

divide equation 2 through by 2

x + y = 9 3/4  equation 3

subtract equation 1 from 3

2y = 6 5/12

y = 77/12 x 1/2 = 3 5/24

substitute for y in equation 1

x - 3 5/24 = 31/3

x = 3 1/3 + 3 5/24

Answer:

240

Step-by-step explanation:

So to do this problem, you have to find the area of each 2d figure. To start off,  you need to find the top sides. (to make this easier I won't show the work)

Green-  Top & bottom: 16. Sides (4): 28

Pink-  Top & bottom: 8. Sides (4): 20

Now you add it all up.

32+112+16+80=240

Answer:

224 in^2

Step-by-step explanation:

The pink rectangular prism has the dimensions 2 x 4 x 10 and the green has the dimensions 4 x 4 x 7. The formula for the surface area of a rectangular prism is:

2(lw + wh + lh)

We can substitute to find the surface area of both pink and green:

Pink

2(4 x 4 + 4 x 7 + 7 x 4)

2(16 + 28 + 28)

2(72)

144

Green

2(2 x 4 + 4 x 10 + 2 x 10)

2(8 + 40 + 20)

2(68)

136

The sum is 280. We have over-counted the part where the two prisms are next to each other. The area of the counted rectangle is 4 x 7 or 28. We over-counted twice, so we need to subtract 2 x 28 or 56.

280 - 56 = 224 in^2

the answer should be 26.4!

During summer vacation, Tori read, on average, 40 pages per night. Now that she has returned to school, she is averaging 5% fewer. How many pages per night is Tori averaging now?

Answers

Answer: 38 pages per night

Step-by-step explanation:

Tori used to read an average of 40 pages per night but now she is going at a rate that is 5% slower.

To find the number of pages she is reading now, first find 5% of 40 pages:

= 5% * 40

= 2

Then subtract this figure from 40:

= 40 - 2

= 38 pages per night

By deducting 5% from the reading quantity, the person is reading at 5% less.
