Find The Area Of The Shaded Region. Help Pls

Answers

Answer 1

Answer:

1. 50 m

2. 80 cm

Step-by-step explanation:

1. There are 2 triangles, subtract the area of 1 of them from the other.

The triangle that needs to be subtracted: b = 20 m, h = 10 m

A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m

The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150

150 - 100 = 50 c

2. Divide it into 3 parts:

1- 3*4 = 12

2. 7*(4 + 4) = 7*8 = 56

3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12

12 + 56 + 12 = 80 cm

At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3. What is the density of the ice? Explain the steps you took to solve this problem.

Answers

Answer:

0.3

Step-by-step explanation

The formula to find density is m/v=p

m=mass

v=volume

p=density

---------------------------

All we have to do is plug in 6g and 20cm^3

This will give us 6/20 which simplifies to 3/10

With this you can easily figure out that the decimal for 3/10 is 0.3

So the density of the ice is 0.3

The probability of landing on blue when spinning a spinner is 4/5. Choose the likelihood that best describe the probability of this event

A) unlikely

B) likely

C) certain

D) neither likely or unlikely

Answers

Answer:

B) likely

Step-by-step explanation:

4/5 or 80%

If the answer is certain it would be 100% or 5/5 but it is 4/5 wich gives it the possibility to land on a different color than blue

The likelihood that best describe the probability of the event is option (B) likely is the correct answer.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

On spinning a spinner the probability of landing on blue = 4/5

⇒ [tex]80\%[/tex]

Then there is 80% chances that the spinner will land on blue.

Thus the likelihood that best describes the probability of this event is likely.

Hence we can conclude that the likelihood that best describe the probability of the event is option (B) likely is the correct answer.

The probability of the letters spelling CAT is 1/6; the sample space consists of 6 outcomes; the probability that T will be the first letter chooses in 1/3

If you count the amount of options at the end there are 6 which means the sample space is 6 and that you have a 1/6 chance of getting any of the options. Because there are only 3 cards, there is a 1/3 chance of any given card being chosen first.

Answers

Answer:

(3,2)

Step-by-step explanation:

2x+5y=16

3x-5y=-1

Subtract 2x from the first equation

5y=16-2x

Substitute the given value of 5y into the equation

3x-(5y)=16

3x-(16-2x)=-1

Solve for x

3x-(16-2x)=-1

3x-16+2x=-1

5x-16=-1

5x=15

x=3

Substitute the given value of x into the equation

3x-5y=-1

3*3-5y=-1

Solve

3*3-5y=-1
