the temperature in an experiment is increased at a constant rate over a period of time until the temperature reaches 0 degrees celsius. the equation y=5/2x-70 gives the temperature y in degrees celsius x hours after the experiment begins. Find and interpret the x- and y- intercepts.

Answers

Answer 1

Answer:

x = 28 (So it takes 28 hours for the temperature to reach 0°C.)

y = -70 (So the temperature when the experiment begins is −70°C.)

Step-by-step explanation:

To find the the x value, you remove the y value or replace it with 0.

0 = 5/2x - 70

Next you move the variable.

70 (2/5) = x           (multiply 70 by 2 to get 140 and divide that by 5)

And now you simplify to get:

28

To find the y value, you remove the x value or replace it with 0.

y =  0 - 70

And now you simplify to get:

-70

x = 28

y = -70

Answer 2

x = 28 (So it takes 28 hours for the temperature to reach 0°C.)

y = -70 (So the temperature when the experiment begins is −70°C.)

This is because 15 times 4 equals 60 and that is equal to 1 hour, well when your multiplying fractions what you do to the bottom you have to do to the top so multiply 3 times 4 thats 12 and now you have 12/4 and that is equal to 3.

Mohammed built a building that can carry up to 5 tons. If each person weighs about 150 pounds, how many people can fit onto the building that Mohammed built?

Answers

Answer:

Step-by-step explanation:

To start solving this problem, you need to figure out how many Pounds( I'll use lbs.) = 5 Tons( I'll use T).

2,000 lbs. = 1 T.

X 5               X 5

10,000 lbs. = 5 T.

Now we divide. That just means that if we know that 1 person( I'll use P) = 150, we just divide 5 T( 10,000 lbs.) by 150 lbs.

10,000/150=66.6666666667

John spent $19.00 at the tuck shop. He bought 2 chocolate bars and 3 packets of
chips. The amount he spent on chips was $3.00 greater than the amount he
spent on chocolate. Jane wants to buy 3 chocolate bars and 3 packets of chips.
How much will it cost her?

Answers

Answer:

It will cost Jane $21.00

Step-by-step explanation:

As, cost of 1 chocolate = x

The cost of 1 packet of chips = $3 + x

So no. Of 2 chocolate bars = x + x = 2x

And no. Of packet of chips = ($3+x) + ($3+x) + ($3+x) = 3(3+x) = 9+3x

So now = cost Of chocolate + cost of chips = $19

So = 2x + 9+3x = 9 + 5x

So 9 + 5x = $19

So 5x = $19 - 9 = $10

So 5x =10

x = 10/5

x = 2

So cost of 2 chocolate = 2x = 2($2) = $4

And 3 chip packet = 9+3x = 9+3($2) = 9+6 =$15

So now total = $4 + $15 = $19

Now for John = 2 chocolates and 3 packets of chips = $19

Now for Jane she has 3 chocolates and 3 packets of chips, so she has one more chocolate amd now we know that 1 chocolate = $2

So we will just add one more chocolate

So Jane will pay = $ 19 + $2 = $21

So it will cost Jane = $21:00

Elon sent a chain letter to his friends, asking them to forward the letter to more friends. The relationship between the elapsed time, t, in days, since Elon sent the email, and the total number of people who receive the email, P(t), is modeled by the following function: P(t)=4×3^t​

Answers

Answer:

Growing by 3's

Step-by-step explanation:

Every day, the number of people who receive the email increases by a factor of 3.

We have,

In the function, P(t) = [tex]4 \times 3^t,[/tex] the base of the exponent is 3.

This means that for each additional day (t), the exponent increases by 1, and multiplying by 3 represents the growth factor.

For example, if we consider t = 0 (the day Elon sent the email), we substitute t = 0 into the function:

P(0) = 4 * [tex]3^0[/tex] = 4 * 1 = 4

On the first day, 4 people received the email.

If we consider t = 1 (the day after Elon sent the email):

P(1) = 4 * [tex]3^1[/tex] = 4 * 3 = 12

On the second day, the number of people receiving the email increased by a factor of 3 (from 4 to 12).

Similarly, on the third day:

P(2) = 4 * 3² = 4 * 9 = 36

The number of people receiving the email increased by a factor of 3 (from 12 to 36).

This pattern continues, and for each additional day, the number of people who receive the email increases by a factor of 3.

Therefore,

The number of people who receive the email increases by a factor of 3 every day.

Step-by-step explanation:

This is because 24/3=8

48/4=12

168/12=14

168/8=21

21-14=7

It take him 7 hours to earn the money if he only does yardwork for his grandmother.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Leroy wants to buy a new racing bicycle that costs $168. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting.

We need to find the time take to earn the money if he only does yardwork for his grandmother.

Thus, $24 for 3 hours of yardwork

24/3=8

Again, $48 for 4 hours of babysitting.

48/4=12

Now, 168/12=14

168/8=21

The time difference is;

21-14=7

Which function can be used to find f, the amount of money Lisa will have saved after walking the neighbor's dog d times? A. F = 50d + 6 B. F = −6d + 50 C. F = −6d + 44 D. F = 6d + 50

Answers

Answer:

Option D. is the correct answer.

The function that can be used to find f, the amount of money Lisa will have saved is F = 6d + 50

Step-by-step explanation:

From the question,

Lisa is saving $50 that she received from her grandmother,

Also, she earns $6 each time she walks her neighbor's dog, which she also saves.

Now, to determine the function that can be used to find the amount of money Lisa will have saved after walking the neighbor's dog d times, we will determine how much she will earn from walking the dog d times and then add it to the money she received from her grandmother. \

If she earns $6 each time she walks her neighbor's dog, then

she will earn $6×d if she walks the neighbor dog for d times.

$6 × d = $6d

Hence, she will earn $6d from walking the dog d times.

The total amount she will have saved will be $6d + $50.

Hence, the function that can be used to find f, the amount of money Lisa will have saved is F = 6d + 50.

Option D. is the correct answer.

3x-y=5
write each equation in slope-intercept form

Answers

Answer:

y = 3x - 5

Step-by-step explanation:

3x-y=5

-3x     -3x

-y= -3x + 5

divide each number by -1

-y/-1 = y

-3x/-1 = 3x

5/-1 = -5

The equation 3x - y = 5 can be converted to slope-intercept form as follows: y = 3x - 5

Given is an equation 3x - y = 5, we need to convert it in slope-intercept form.

To convert the equation 3x - y = 5 into slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate the variable "y" on one side of the equation.

Let's rearrange the given equation step by step:

Starting with 3x - y = 5, we can begin by moving the term involving "x" to the other side:

3x - y + y = 5 + y

Simplifying:

3x = y + 5

Now, let's isolate "y" by subtracting "y" from both sides:

3x - y = y + 5 - y

Simplifying:

3x - y = 5

To eliminate the "y" term on the left side, we can add "y" to both sides:

3x - y + y = 5 + y

Simplifying:

3x = 5 + y

Next, let's rearrange the equation to have "y" on the right side:

3x = y + 5

We can write this equation as:

y = 3x - 5

Now the equation is in slope-intercept form (y = mx + b), where the slope "m" is 3, and the y-intercept "b" is -5.
