If she practiced 70 minutes on Tuesday and and 70 is 7 times as much as she practiced on Monday then you would use the equation 70/7 (70 divided by 7) So the answer would be 10

Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hu
olga nikolaevna [1]

Answer:

I hope that you are doing well, during this weird time; and that this message finds you in a good place.

To get you started on this problem, you will want to think about how to go about graphing this linear function. You want to keep in mind that you want to plot your dependent variable on the y-axis, as it changes with respect to your independent variable (plotted on the x-axis). In this problem, the cost of the water bill depends on the amount of water used, in HCF. So the graph should be plotted with cost on the y-axis, and HCF on the x-axis.

It follows that you are given the coordinates of (16, $48.37) and (22, y2); where y2 represents the cost when using 22 HCF. You are also given the slope of your line (m, in y = mx + b format). You may recall that you can set-up a slope as the change in y over the change in x, or the "rise over the run" [m = (y2-y1) / (x2-x1)]. We can set this problem up, using this equation to solve for y2 (the cost at 22 HCF) algebraically.

So we would set up the problem as 1.65 = (y2-48.37)/(22-16). We then solve by combining like-terms and using inverse operations as follows:  

  1.65 = (y2 - 48.37) / 6

  1.65(6) = y2 - 48.37

  9.9 = y2 - 48.37

  y2 = $58.27

A group of friends wants to go to the amusement park. They have no more than $310
Marizza181 [45]

Answer: 35x+9\leq 310,\ 8

Step-by-step explanation:

Given

A group of friends has $310 to spend

Parking costs $9 and ticket cost $35 per person

Suppose  there are x friends who go to amusement park

So, the cost of tickets and parking must be less than or equal to $310

\Rightarrow 35x+9\leq 310\\\text{Subtract 9 from both sides}\\\Rightarrow 35x\leq 301\\\text{Divide both sides by 35}\\\Rightarrow x\leq 8.6

This indicates that there sholud be maximum 8 persons who can go to amusement park with this much money.

Evaluate: log1255<br> - |<br> - |<br> N |<br> DONE<br> o<br> o<br> o
Bas_tet [7]

Answer:

\log_5(125) =3

Step-by-step explanation:

Question:

To evaluate \log 125 to the base 5

Solution:

We will apply log properties to evaluate.

We will use the following property of logarithms

If \log _ab=x

Then, a^x=b

Let \log_5(125) =x

So, we have

5^x=125

We can write 125=5\times 5\times 5=5^3

5^x=5^3

∴ x=3

Thus, we have

\log_5(125) =3

What is the kinetic energy of a 54 kg mass traveling at 15 meters per second?
kobusy [5.1K]

Given that an object with a mass of 54kg travels at 15m/s^2, determine the kinetic energy of the object.

KE =  0.5 x mv^2

M (mass) = 54kg

V (velocity) = 15m/s^2

Then, we plug the values in.

KE =  0.5 x 54(15^2)

Now, we solve.

KE = 0.5 x 54(225)

KE = 0.5 x 12150

KE = 6075

Now, that we have solved the formula, we can see that the kinetic energy of the object is 6,075J.

Thus, the kinetic energy of the object is 6,075J.
