Answer:

Ratio should be equal so ratio is 3:3

The ratio of the triangles to circles in the diagram below would be; 1: 1

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained.

Thus, there are three circles and three triangles shown in the figure.

Therefore, the ratio will be;

three circles: three triangle

3 : 3

1: 1

Hence, the ratio of the triangles to circles in the diagram below would be; 1: 1

Answer:

2,304in^3

Step-by-step explanation:

The formula for volume is [ b * l * h ]. We can use the values we are given to find the volume of both rectangles then add them both together.

12 * 12 * 6 = 864in^3

18 * 10 * 8 = 1,440in^3

Add them both together.

864 + 1440 = 2,304in^3

Answer:

x=37°

Step-by-step explanation:

2x°=74° (vertically opposite angles)

2x°/2=74°/2

x=37°

74° = 2x°

2x° = 74°

x° = 74° : 2

x° = 37°

Answer:

B' = {1, 3, 5, 6, 7}

Step-by-step explanation:

U = {1, 2, 3, 4, 5, 6, 7, 8}

B = {2, 4, 8}

So the complement  ( the set of elements in U but not in B) is:

B' = {1, 3, 5,  6, 7}

Answer:

19, 20, 21

Step-by-step explanation:

You can trial-and-error this where you test each answer out step-by-step or you can graph it and you'll see it will be a line for x = 21 and a shaded region to the left of that (if you get what I mean) and from there, any point on the line x = 21 or any point in the shaded region, will be a viable solution.

Simplifying,

[tex]-\frac{2}{3}s+13>=-1\\-\frac{2}{3}s>=-14\\\frac{2}{3}s=<14\\s=<21[/tex]

Answer:

y is the dependent variable and x is the independent variable

Step-by-step explanation

The number on the right of the equal sign is always the independent variable and the number on the left is always the dependent variable.

independent variable = dependent variable +5

Answer:

40-15x=18

Step-by-step explanation:

Multiply both sides of 2 - 3/4x = 9/10 by twenty to get

20*2 - 20*3/4*x = 20*9/10

which is 40 - 15x = 18

This should be as far as you need to go, but incase you need to go further,

subtract 40 to both sides

multiply both sides by -1 to get rid of the negatives infront of the x

then divide both sides by 15 to get

x=22/15

and yes, when you solve for x, it is a fraction, but just incase if its needed, I included it. Hope this helps in the future! Let me know if any more questions you have on this problem.

Answer:

9 test

Step-by-step explanation:

There should be 9 administrators chosen.

A proportion is a comparison of two numbers that each represent the parts of a whole.

Given that, A supervisor wants to know the average number of hours worked by employees in a factory. There are 18 managers, 240 labourers, and 54 administrators. Three managers are chosen to participate in the survey.

Since, the manager chosen 3 out of 18 managers, hence, the proportion is 1 to 6 persons,

Therefore, when he is choosing administrators, 54/6 = 9

Hence, there should be 9 administrators chosen.

Answer:

-8 and -6.

Step-by-step explanation:

Let the first even integer be a.

Since the second is a consecutive even integer, it is given by (a + 2).

Half of the smaller (i.e. a) is equal to two more than the larger (i.e. a + 2). In other words:

[tex]\displaystyle \frac{a}{2} = (a + 2) + 2[/tex]

Solve for a:

[tex]\displaystyle \begin{aligned}\displaystyle \frac{a}{2} &= (a + 2) + 2\\ \\ \frac{a}{2} &= a + 4\\ \\ a &= 2a + 8 \\ \\ a &= -8 \end{aligned}[/tex]

In conclusion, the two even, consecutive integers are -8 and -6.
