B. F(x) = 9280 - 20x
C. F(x) = -9280 + 20x
D. F(x) = 9280 - 1/16x

Answers

Answer:

the awnser is b hope this helps

Step-by-step explanation:

The equation as a function of x is f(x)=9280-20x. Therefore, option B is the correct answer.

The given function is x/16 + y/320 - 29 = 0.

What is a function?

Functions are the fundamental part of calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters such as f, g, and h. The domain is defined as the set of all the values that the function can input while it can be defined. The range is all the values that come out as the output of the function involved. Co-domain is the set of values that have the potential of coming out as outputs of a function.

Now, the LCM of denominators 16 and 320 is 320.

So, 20x/320 + y/320 - 9,280/320 = 0

⇒20x+y-9280=0

⇒y=9280-20x

The equation as a function of x is f(x)=9280-20x. Therefore, option B is the correct answer.

in a school containing 360 children, 198 are girls. What percent of the school are girls? What percent of the school are boys? How many boys are there? How many girls are there? Thank you!

Answers

Answer:

Part A)

Part B)

Part C)

Part D)

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

Let

x------> size of the event space

y------> size of the sample space

P=x/y

Part A) What percent of all children are girls?

we have that

y= 360 children

x=198 girls

substitute

p = 198/360 0.55

Find the percentage

0.55*100=55%

Part B) What percent of all children are boys?

we have that

y=360

x=360-198

substitute

p= 162/360=0.45

Find the percentage

0.45*100=45%

Part C) The number of girls is what percent of the number of boys?

we have that

y=162

x=198

substitute

p=198/162=1.22

Find the percentage

1.22*100= 122%

Part D) The number of boys is what percent of the number of girls?

we have that

y=198 girls

x=162 boys

substitute

p=162/198=0.8182

Find the percentage

0.8182*100=81.82%

The percentage of the school are girls is 55%.

The percentage of the school are boys is 45%.

The number of boys in the school is 162.

The number of girls in the school is 198.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, In a school containing 360 children, 198 are girls.

Therefore, The percentage of the school are girls is,

(198/360)×100%.

= 55%.

The percentage of the school are boys is,

= [(360 - 198)/360]×100%.

= 45%.

Or The percentage of the school are boys is, (100 - 55)% = 45%.

The number of boys in the school is,

(360 - 198).

= 162 boys.

The number of girls in the school is 198.

#SPJ2

If y=3x+4 and y=2x+8 find the value of both x and y

Answers

Answer:

x=4, y=16

Step-by-step explanation:

Since y is alone on one side of both equations, that means that the equations are equal.

[tex]2x+8=3x+4\\[/tex]

Put like terms on the same side of the equations. I put the numbers on the left and the Xs on the right. To do this subtract 4 from both sides. You will get:

[tex]2x+4=3x[/tex]

Next, I subtracted the 2x from both sides;

[tex]4=x[/tex]

For y, just substitute the x in the equation with 4. Will work for either equation.

[tex]y= 3(4)+4\\y= 12+4\\y=16[/tex]

[tex]y=2x+8\\y=2(4)+8\\y=8+8\\y=16[/tex]

Therefore, y=16

Jaden and Dani are both travelling by train.
Jaden's train travels 130 km in 75 minutes.
Dani's train travels 312 km.
It leaves at 15:15 and arrives at 18:30.
Work out the difference, in km/h, between the average speed of their trains.

Answers

Answer: 28.765957 km/hour

This value is approximate. Round it however you need to.

==============================================

Explanation:

Let's convert 75 minutes to hours.

75 min = (75 min)*(1 hr/60 min) = (75/60) hr = 1.25 hr

So Jaden's train takes 1.25 hours to travel 130 km. Her train's speed is

speed = distance/time

speed = (130 km)/(1.25 hrs)

speed = (130/1.25) km per hour

speed = 104 km per hour

Let A = 104, so we can use it later.

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

Dani's train leaves at 15:15 and arrives at 18:30. We need to calculate the duration of elapsed time here.

From 15:15 to 16:00, this is a difference of 00:45, aka 45 minutes or 45/60 = 3/4 = 0.75 hours.From 16:00 to 18:00, this is a time gap of 2 hours. From 18:00 to 18:30, this is a gap of 30/60 = 0.5 hours

Overall, the length of time from 15:15 to 18:30 is 0.75+2+0.5 = 3.25 hours.

Dani's train travels 312 km in 3.25 hours.

That train's speed is...

speed = distance/time

speed = (312 km)/(3.25 hours)

speed = (312/2.35) km per hour

speed = 132.765957 km per hour, approximately

Let B = 132.765957 so we can use it later.

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

Lastly, we subtract the values of A and B to get the final answer

C = difference in train speeds.

C = B - A

C = 132.765957 - 104

C = 28.765957 km/hour

This value is approximate. This says that Dani's train is approximately 28.765957 km/hour faster compared to Jaden's train.

PLEASE HELP Bill receives a monthly stipend of $800. He also works at a bookstore making $8 an hour. He wants a monthly income of $1,200.
How many hours does he need to work each month?

Answers

Answer:

Bill will need to work 50 hours every month.

Step-by-step explanation:

First, we subtract the stipend from the total income he wants to have since he will already recieve it.

[tex]1200 - 800 = 400[/tex]

From this 400 dollars, we can divide it by 8, or his hourly rate to find the rest of the time he needs to work.

[tex]\frac{400}{8}=50[/tex]

Bill needs to work 50 hours to make his total income of 1200.
