What is the measure of ∠E?

Answers

Answer:

80 degrees

Step-by-step explanation:

first we need to find the measure of F, we know a straight line equals 180 so we subtract 120 from 180

180-120=60

then add that to angle D

60+40=100

and all triangle angles add up to 180 so subtract 100 from 180

180-100=80

80 is your answer

The top three oil producers in the United States in a certain year were the Gulf of Mexico, Texas, and Alaska. The three regions were responsible for 64% of the United States oil production. The Gulf of Mexico and Texas combined for 47% of oil production. Texas produced 3% more than Alaska. What percent of United States oil production came from these regions?

Answers

Answer:

27% of United States oil production came from Gulf of Mexico.

20% of United States oil production came from Texas.

17% of United States oil production came from Alaska.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

Gulf of Mexico produced x%.

Texas produced y%.

Alaska produced z%.

The three regions were responsible for 64% of the United States oil production.

This means that:

[tex]x + y + z = 64[/tex]

The Gulf of Mexico and Texas combined for 47% of oil production.

This means that [tex]x + y = 47[/tex].

We use this to find z.

[tex]47 + z = 64[/tex]

[tex]z = 64 - 47 = 17[/tex]

17% of United States oil production came from Alaska.

Texas produced 3% more than Alaska.

Then:

[tex]y = z + 3 = 17 + 3 = 20[/tex]

20% of United States oil production came from Texas.

Gulf of Mexico

[tex]x + y = 47[/tex]

[tex]x = 47 - y = 47 - 20 = 27[/tex]

27% of United States oil production came from Gulf of Mexico.

Answer: x = 2.5

Step-by-step explanation:

Try to get x by itself

Explain the meaning of probability. What does it mean if an event has a probability of 0? Give an example. What does it mean if an event has a probability of 1? Give an example. What does it mean if an event has a probability of 1/2? Give an example. (LONG ANSWERS ONLY)

Answers

Answer:

If an event has a probability of 0 it means that it is impossible. For example when they say there is 0% of rain. It is very unlikely it is going to rain. If an event has a probability of 1 it means that it is certain. For example, if they say there is a 100% chance it is going to rain. It is very certain that it's going to rain. If an event is 1/2 then it means there it is likely as it is unlikely. For example, if they say there is a 50% chance of rain. Then it might not rain, but there is a chance that it might rain as well.  

Step-by-step explanation:

Hope this helps!

Probability can simply be defined as the chances of an event a, occuring with respect to event b, with respect to event n, given an nth number of possible outcomes.

Probability can be calculated using the following expression:

[tex] \frac{freq \: of \: event \: n}{freq \: of \: total \: number \: of \: events} [/tex]

When an event has a probability of 0, it means that by no chance or condition will the event be true. For example, the probability of a person who is a boy has 0 probability that he is a girl.

When an event has a probability of 1, it means that with every chance or condition, the event will be true. For example, the probability that a person who is a boy has a probability of 1 that he is a boy.

An event that has a probability of 1/2 means that the event could either return a probability of 0 or 1 on different chances or conditions. For example, the probability of a fuetus whose gender is not known has a probability of 1/2 for being a boy and 1/2 for being a girl.

what is the value of y in the following system of equations ? 2x + 3y = 6 2x + y = -2

Answers

y = 4

Step-by-step explanation:

2x + 3y = 6. #1

2x + y = -2. #2

Subtract Eq 2 from Eq 1,

3y - y = 6 - (-2)

2y = 8

or

y = 4

Answer:

y = 4

Step-by-step explanation:

2x + 3y = 6

2x + y = -2

Let's set the second equation equal to y. This means that y will be alone on one side of the equal sign.

2x + y = -2

Subtract 2x from both sides.

y = -2x - 2

Now that we have y as an expression, plug it into the first equation.

2x + 3y = 6

2x + 3(-2x - 2) = 6

Distribute the 3 across the parentheses by multiplying.

2x - 6x - 6 = 6

Combine like terms.

-4x = 12

Divide both sides by -4.

x = -3

Now we have solved x.

To solve for y, plug x back into one of the equations.

y = -2x - 2

y = -2(-3) - 2

Multiply.

y = 6 - 2

Subtract.

y = 4

Check your answer by plugging both values back into the original equations.

2x + 3y = 6

2(-3) + 3(4) = 6

Multiply.

-6 + 12 = 6

Add.

6 = 6

Your answer is correct.

Hope this helps!

8. At a wholesale food distribution center, the price of sugar has increased 6.3% annually since 1980.
Suppose sugar cost $0.43 per pound in 1980 and this growth continues. What will a pound of sugar
cost in 2017? Use y = a(1 + r) and round to the nearest cent.
a. $4.12 b. $1.21
c. $0.42 d. $3.30

Answers

Answer: A. $4.12

Step-by-step explanation:

Y=a(1+r/n)^nt is the equation we use to solve this.

a= $0.43

t=37 - take 1980 and subtract it from 2017

r= .063 - the 6.3% goes into a decimal

n = 1

Y= ?

Y= 0.43( 1+ .063/1) ^1*37

Y= 0.43 (1.063) ^37

Y= 4.12

The lateral areas of two similar cylinders are 196π in^2 and 324π in^2. The volume of smaller cylinder is 1715π in^3. Find the volume of the larger cylinder.

Answers

Answer:

3,645 π in³

Step-by-step explanation:

the ratio of the radius :

r1 : r2 = √196 : √324

= 14 : 18

= 7 : 9

the ratio of the volume:

v1 : v2 = 7³ : 9³

= 343 : 729

so, the volume of the larger cylinder =

729/343 x 1715π = 3,645 π in³

Answer:

since the cylinders are similar their area and volume will be proportional

[tex]\frac{lateral\:area \:of \:smaller \:cylinder}{laternal\: area \:of \:larger\: cylinder}=\frac{volume \:of\: larger\: cylinder}{volume \:of \:larger \:cylinder}[/tex]

[tex] \frac{196π}{324π}=\frac{1715π}{V}[/tex]

V=1715π*324π/126π

V=4410πin³

the volume of the larger cylinder is 4410πin³.
