Answers

Answer:

7, 8 and 9

Step-by-step explanation:

Two-digit numbers are:

ab, ac, ba, bc, ca, cb

Sum of them is:

10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 52822a + 22b + 22c = 528a + b + c = 528/22a + b + c = 24

The only option of three different digits with the sum of 24 is 7, 8 and 9

Answer:

The answer is 7, 8 and 9. The Two-digit numbers are: ab, ac, ba, bc, ca, cb

The Sum of them is: 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528

22a + 22b + 22c = 528

a + b + c = 528/22

a + b + c = 24      The only option/options of the three different digits with the sum of 24 is 7, 8 and 9.

Hope this helps, stay safe, and merry christmas!

The lines graphed below show the amounts of water in two tanks as they were being filled over time.For each tank, explain whether or not there is a proportional relationship between the amount of water, in gallons, and the time, in minutes. If there is a proportional relationship, identify the unit rate. Use specific features of the graph to support your answer.
3 points

Answers

Answer: Tank B is proportional because tank A doesn't work because it doesn't go through (0,0) but if it was y=kx, then it would have to go through (0,0), since 0=k*0. For tank b k is 300.

I got 100 for this so gl

The relationship between time and the volume of water in Tank B is proportional.

What is a line graph?

A line graph is a type of graph where the data points are connected by segments of straight lines.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have a line graph shown in the picture.

As we know,

Variables in a linear function will be proportionate if it passes through the origin.

y = mx + b

b is y-intercept = 0

y = mx

The relationship between time and the volume of water in Tank B is proportionate since the straight line passes through the origin.

Thus, the relationship between time and the volume of water in Tank B is proportional.

Answers

Answer:

essentially, in these problems, youre finding the square root of each number. the square root should be a decimal thats in between two other numbers, and those will be the integers that the value of the square root is between. unless the value is exactly a number and a half, it will be closer to one integer than the other. the work is below.

square root of:

59= 7.68

68= 8.246

78= 8.83

93= 9.64

104= 10.198

124= 11.14

33= 5.74

185= 13.6

215= 14.66

these are just the square roots. but, as you can see, each number is between two other whole numbers on a number line. So, just write down what those numbers are.

7.68 is between 7 and 8

8.246 is between 8 and 9

8.83 is between 8 and 9

9.64 is between 9 and 10

10.198 is between 10 and 11

11.14 is between 11 and 12

5.74 is between 5 and 6

13.6 is between 13 and 14

14.66 is between 14 and 15

so, we know thw numbers that each decimal is between, but we have to find which one each is cloest to. in order to do that, just know that if the decimal is more than .5 its closer to the larger number, and its its less than .5, its closer to thw smaller number.

7.68 is closer to 8

8.246 is closer to 8

8.83 is closer to 9

9.64 is closer to 10

10.198 is closer to 10

11.14 is closer to 11

5.74 is closer to 6

13.6 is closer to 14

14.66 is closer to 15

  (f ◦ g)(3) = f(g(3))

Each of the coordinate pairs for g correspond to ...

  (x, g(x))

Then g(3) can be found by looking for the pair that has 3 in the first location. That ordered pair is ...

  (3, 4)

so we know that g(3) = 4.

Now, we know that f(g(3)) = f(4). This tells us to look for the ordered pair in the f relation that has 4 as its first value. That ordered pair is ...

  (4, 9)

so we know that f(4) = 9.

__

In summary, ...

  (f ◦ g)(3) = f(g(3)) = f(4) = 9

Solve for elimination

Answers

Answer:

The solution is x=-6 and y=7

Step-by-step explanation:

Given equations are:

[tex]4x+4y =4\\3x+4y = 10[/tex]

In elimination method, the co-efficient of one of the variables are equated so that one variable can be eliminated by adding or subtracting the equations

In the given system of equations, the co-efficient of y is already same i.e. 4 so we only have to subtract the equations

Subtracting equation 2 from equation 1

[tex]4x+4y-(3x+4y) = 4-10\\4x+4y-3x-4y = -6\\4x-3x = -6\\x = -6[/tex]

Putting x = -6 in equation 1

[tex]4(-6)+4y = 4\\-24+4y = 4\\4y = 4+24\\4y = 28\\\frac{4y}{4} = \frac{28}{4}\\y = 7[/tex]

Hence

The solution is x=-6 and y=7
