Which graph shows a proportional relationship between the number of hours of renting a camping tent and the total amounts back to work for camping tent?

Answer:

The third option with the decimal on top as a fraction

Answer:

C

Step-by-step explanation:

Think of the proportional relationship as algebra.

k*number of MovieTickets = Cost, where k is the constant of proportionality.

To find k, you can substitute values in the table and solve for k.

In this example:

k*5 = $28.75

k = $28.75/5

This answer is C.

Answer:

Difference in area of the last square and the initial square = 440 cm²

Step-by-step explanation:

Length of the side of a square = 1 cm

Area of the square = (side)² = 1 cm²

Addition of side length every minute = 2 cm

After x minutes length of each side of the square = (1 + 2x) cm

If x = 10 minutes

Length of each side of the square = [1 + 2(10)]

                                                         = 21 cm

Area of the square after 10 minutes = (21)²

                                                            = 441 cm²

Therefore, difference in area of the last square and area of the initial square

= 441 - 1

= 440 cm²

Answer:

C. 350 - acres of pumpkins

Step-by-step explanation:

The Uncle owns 510 acres, and wants 190 more acres of pumpkin than squash totaling at 510.

When looking at the possible answers D is automatically wrong since the Uncle only owns 510 acres. When I added A and C I got 510 as an answer;

160 + 350 = 510

So he wants 190 more pumpkin acres than squash so 160 represents the squash and 350 represents the pumpkin.

160 + 190 = 350

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

Another way to find the answer is by taking 510 and subtracting 190 then dividing by two;

510 - 190 = 320

320 / 2 = 160

160 + 190 = 350

Then 160 would be squash and 350 would be pumpkin.

I hope this helps!

Answer:

f(1) = 1

Step-by-step explanation:

To go 1 on the x-axis and check to see where it is on the y-axis. In this case, when x = 1, y = 1.

Therefore, f(1) = 1.

Multiply:

[tex](\frac{5}{5+\sqrt{10x} } )(\frac{5+\sqrt{10x} }{5+\sqrt{10x} } )[/tex]

Simplify:

Answer:

3= x - 7 (write out the equation and think of what number with 7 subtracted would be equal to 3)

3= 10-7 (10-7 is equal to three, so that's what x has to be)

x=10

value of y in triangle is D. 36° okay

9514 1404 393

Answer:

  30°

Step-by-step explanation:

The angle a line makes with the x-axis is arctan(slope). Here, that is ...

  angle with x-axis = arctan(√3) = 60°

So, the angle made with the y-axis is the complement of this:

  angle with y-axis = 90° -60° = 30°

Answer:

I believe the answer is B

Answer:

negative trend because the values are decreasing

Answer:

This is a vertical line; there is no change in the x coordinate value; and since the slope is defined to be change in y any attempt to corresponding change in x evaluate the slope would result in an attempt ot divide by zero.

There your answer hope it helps.

Answer:

For a function f(x) = y.

The independent variable is the one that we chose to input in the function, in this case, is x, and the dependent variable is the variable that changes in response to the independent variable, in this case, is y.

In this problem we have:

"Sammy has $180 in her savings account and plans to deposit $20 each month."

We can define:

y = money in her savings account

x = number of months that have been passed since she started saving.

Originally, she has $180, and she saves $20 per month, so if x months have been passed, the total amount of money in her savings account is:

y = f(x) = $180 + $20*x

Now we want to know if this function is continuous or discrete, to see this we need to look at the possible values of x.

x represents the number of months that have been passed, then the values that x can take are:

x = 0, 1, 2, 3, 4, ...

So x can only take the values of positive integers, this means that the domain of x is discrete, then the function f(x) is a discrete function.

30% of lightbulbs = 45 lightbulbs

100% of lightbulbs

= 45 * (100/30) = 150 lightbulbs.

Hence there are 150 lightbulbs in the batch.

1 1/3 - miles per hour.

Step-by-step explanation:

(1/3) / (1/4) =

(1/3) x (4/1) =

4/3 = 1 1/3

Answer:

1 ½% of x = 15

3/2 × x = 15

x = 15/1.5

x = 10

So

1½ 15
