of the line through the points (10,3) and

Answers

Answer:

y-3=4(x-10)

Step-by-step explanation:

Point Slope Form: y-y1=m(x-x1)

Where m=slope and (x1, y1) is a point on the line.

m=(y2-y1)/(x2-x1)=(11-3)/(12-10)=8/2=4

So the slope is 4,

y-3=4(x-10)

Find the slope of the line that goes through the given points.

Answers

Answer: 0

Step-by-step explanation:

describes a horizontal line

so slope = 0

Answer:

0/2

Step-by-step explanation:

you have to subtract the x's and then then the y's, y is always on top. So, y=2-2/ x= 7-5 making 0/2 When the 0 is on the "top" of the fraction, that would mean that the two y-values are the same.

Second, you would naturally multiply both sides by -3. To solve the equation, you need to use the inverse operation in the inverted order of PEMDAS. (Parentheses, exponent, multiplication, division, addition, and subtraction.)

2) -3(-x/3)=-3* 2

Lastly, you are going to reduce and simplify your new equation. This last step will achieve you your desired answer.

A. HOW MANY PACKETS WOULD BE NEEDED TO TRANSMIT 30,000BYTES OF INFORMATION
B. HOW MUCH INFORMATION COULD BE TRANSMITTED IN 30,000 PACKETS

Answers

Answer:

A. It would be needed 20 packets to transmit 30,000 bytes of information.

B. 45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Size of each packet of information = 1,500 bytes

Number of packets = P

Number of bytes of information = B

2. Let's answer the questions:

A. How many packets would be needed to transmit 30,000 bytes of information?

P = 30,000 ÷ 1,500

P = 20

It would be needed 20 packets to transmit 30,000 bytes of information

B. How much information could be transmitted in 30,000 packets?

B = 30,000 * 1,500

B = 45'000,000

45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

A survey of all beings on planet Tott found that 12 beings preferred
hab juice to all other juices. If 40 beings were surveyed altogether,
what percent of them preferred hab juice?

Answers

Answer:

4.8

12 x 40

100

= 4.8

Step-by-step explanation:

The percentage of beings that preferred hab juice, is 30% of beings preferring hab juice.

The question is asking to find the percentage of beings that preferred hab juice out of a total of 40 surveyed on planet Tott. To do this, we use the basic formula for percentage:

Percentage = (Part / Whole) * 100

In this case, 12 beings out of 40 preferred hab juice. So we have:

Percentage = (12 / 40) * 100 = 0.3 * 100 = 30%

Therefore, 30% of the beings surveyed preferred hab juice.

Step-by-step explanation:

The pH level of a substance indicates the concentration of hydrogen ions ([tex]H^{+}[/tex]) in a solution and is calculated by:

In this case the hydrogen ion concentration is [tex]0.095811180 M[/tex], where

Answers

Answer:

36 feet.

Step-by-step explanation:

h = -16t² + 48t .......... (1)

The above equation relates the height h, in feet of the water at time t, in seconds.

Now, condition for greatest height is [tex]\frac{dh}{dt} = 0[/tex] ......... (2)

So, differentiating equation (1) with respect to t we get, -32t + 48 = 0 {From condition (2).

t = 1.5 seconds

How do you round to 630 to the nearest hundred

Answers

Answer: Here we will tell you what 630 is rounded to the nearest hundred and also show you what rules we used to get to the answer.

Remember, we did not necessarily round up or down, but to the hundred that is nearest to 630.

First, 630 rounded to the nearest hundred is: 600

When rounding to the nearest hundred, like we did with 630 above, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Step-by-step explanation:

Rounding 630 to the nearest hundred results in 600.

To round the number 630 to the nearest hundred, consider the tens digit of the number.

In this case, the tens digit is 3.

If the tens digit is 5 or greater, you round up to the next hundred.

If the tens digit is 4 or less, you round down to the current hundred.

Since the tens digit in 630 is 3, which is less than 5, you round down.

Therefore, rounding 630 to the nearest hundred results in 600.

A surveyed was conducted at Holy Spirit High school where 50 students were randomly
chosen and asked whether they liked apples or bananas. Of the 50, 36 students said they
like apples, 30 students like bananas and 5 students do not like either apples or bananas.

How many students like both apples and bananas?

Answers

Answer:

26

Step-by-step explanation:

50 students were asked, and only 5 said that they did not like apples or bananas.This means that  45 students like either apples or bananas, or both of them. We will call these 45 students, the group of "45".We also know that, between these 45 students there are 36 who like apples and 30 that like bananas. This imply that, 45-36=9 students do not like apples, and 45-30=15 students do not like bananas.Then, there are 15 students within the group of "45" that do not like bananas, and 9 students within the group of "45" that do not like apples. This means that 9+15=24 students within the group of "45" only like bananas or apples. The rest of them, 45-24= 26 like both apples and bananas.

Answers

Answer:

240.

Step-by-step explanation:

Here is the correct question: Three sister are getting new outfits. shirts cost 11 each,skirts coat 25 each and shoes cost 44 a pair. what is the total cost of the new outfits for all of the sisters​?

Given: Cost of each shirt is 11

           Cost of each skirts coat is 25

           Cost of each pair of shoes cost is 44.

Now, finding total cost of shirt, skirt coat and shoes as cost of one new outfit.

= [tex]11+25+44 = 80[/tex]

∴ Total cost of one new outfit is 80.

Next, finding cost of new outfit for all, three sisters.

Cost of new outfit for three sister = [tex]\textrm { cost of one outfit}\times \textrm{ number of sisters}[/tex]

∴ Cost of new outfit for three sister = [tex]80\times 3= 240[/tex]

240 is the total cost of new outfit for all the sisters.

Answers

Answer:

y = -6x + 31

Step-by-step explanation:

In order for us to make this an equation of the form y = mx + b we have to find the slope.

The formula for slope is rise/ run. The rise is 6 and the run is -1.

So, the slope is 6/-1 or -6.

Our equation is now: y = -6x + b

Substituting 4,7 into the equation we get 7 = -24 + b

So, b = 31.
