Given:

The ratio of two numbers is 5:2.

To Find:

What are the other ratios which are equivalent to the above ratio?

Solution:

The given problem can be solved using the concepts of ratio and proportions.

1. It is given that the ratio of two numbers is 5:2.

2. Consider two numbers a and b such that the simplest ratio between the two numbers is a:b.

=> Ratio of the numbers a and b = a:b,

=> According to the properties of ratios the operation a:b can also be written as a/b.

=> a/b can also be written as.

=> a/b can also be written as.

=> Similarly a/b can be conclusively written as. (Where n is not equal to 0).

3. The ratio of two numbers will always remain the same even if the numerator and the denominator are multiplied with the same factor. In such cases, the ratio always remains the same.

4. 5:2 = 5/2 can also be written as,

=>  ... , . (Where n is not equal to zero).

Therefore the ratios 10:4, 15:6, 20:8, 25:10,.., 5n:2n are equal to the ratio 5:2.

The expression is 2 - m/4 + 10, when m = 12, the value is 9. Then the correct option is C.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Two less than the quotient of a number and four, increased by ten.

That can be written as in the form of m will be

[tex]\rm 2 - \dfrac{m}{4} + 10[/tex]

If the value of m is 12, then we have

[tex]\rm 2 - \dfrac{m}{4} + 10\\\\\rm 2 - \dfrac{12}{4} + 10\\\\2- 3 + 10\\\\12 - 3 \\\\9[/tex]

Thus, the expression is 2 - m/4 + 10, when m = 12, the value is 9. Then the correct option is C.

Answer:

x   8  -5

9  72   -45

-6 -48  30

Step-by-step explanation:

We have to complete the multiplication grid, where each cell is the result of multiplying the column lable by the row label.

For the blank in the first column, we have to multiply:

8×(-6)=-48

We now have to find the column label for the second column.

If we call this label x, we know that -6 times x is equal to 30.

Then, we can find x as:

(-6)×x=30

[tex]x=\frac{30}{-6}[/tex]

x=-5

Then, we can complete the first row by multiplying -5 times 9:

-5×9=-45

Then, the table becomes:

x   8  -5

9  72   -45

-6 -48  30

Step-by-step explanation:

The volume of the air mattress in liters is 385.43 liters approx.

For an ideal gas(or a gas that behaves sufficiently like an ideal gas), we have the following relation:

[tex]\rm PV = nRT[/tex]

where, the symbol denotes:

For the given case, the gas in the air mattress has following properties:

P = 3.5 kilopascals =3500 pascals

T =295 K

n = 0.55 moles

V = volume of gas in air mattress = volume of mattress (to evaluate).

Thus, using the ideal gas law, we get:

[tex]V = \dfrac{nRT}{P} = \dfrac{0.55 \times 8314.46261815324 \times 295}{3500} \approx 385.43 \: \rm liters[/tex]

Thus, the volume of the air mattress in liters is 385.43 liters approx.

x = 19

Step-by-step explanation:

(5x + 4)° + (x - 2)° + (3x + 7)° = 180°

Answer:

  both are Quadratic

Step-by-step explanation:

To determine if a table of function values represents a linear function or a quadratic function, you can often look at first- and second-differences of the dependent variable.

The x-values are evenly spaced in each case, so the question can be answered by looking at differences in y-values. The set of first differences is the result of subtracting a given column from the next. The set of second differences is found by doing the same, using the first differences.

First differences; 21 -11 = 10, 35 -21 = 14, 53 -35 = 18, 75 -53 = 22

Second differences: 14 -10 = 4, 18 -14 = 4, 22 -18 = 4

The second differences all have the same value: 4. That means the function is 2nd degree, quadratic.

__

First differences: 10 -12 = -2, 9 -10 = -1, 9 -9 = 0, 10 -9 = 1

Second differences: -1 -(-2) = 1, 0 -(-1) = 1, 1 -0 = 1

The second differences all have the same value: 1. That means the function is 2nd degree, quadratic.

__

Additional comment

The level at which differences are the same tells you the degree of the polynomial that will match the given function points. If first differences are constant, then the function is 1st degree: linear. Here, second differences are constant, so the functions are 2nd degree: quadratic. If you have to go to 4th differences to get constant values, then the table will require a 4th-degree polynomial to match its values. This presumes the x-values are all evenly-spaced.

If the x-values are not evenly spaced, then determining the degree of the function can be done by graphing and/or using regression formulas. Various interpolation polynomials are available for matching the points exactly.

Answer:

40 degrees

Step-by-step explanation:

Sum of all angles of triangle is 180 degrees.

So, 80+(9x+4)+(16x-4)=180

80+25x=180

25x=100 -> x=4

So angle A = 9(4)+4= 40 degrees

Answer:

1/4

Step-by-step explanation:

Dividing a number by something is the same thing as multiplying it by the reciprocal.  To find the reciprocal, you flip the number.

In this case, you are dividing 83 by 4.  The reciprocal of 4 is 1/4.  So the missing number is 1/4.
