Step-by-step explanation:

The number of total students is 18+12+10=40

So

1) 18:40 but simplified it will be 9:20

2) 10:40 but simplified it will be 1:4

3) 30:40 but simplified it will be 3:4

4) 30:10 but simplified it will be 3

5) 18:22 but simplified it will be 9:11

N.B simplified means dividing them by their common multiple. so the final answer for each is the number after it is simplified

Answer:

x = 1

Step-by-step explanation:

a^2 + b^2 = c^2

The hypotenuse (c) and a side length is already given, so:

x^2 + 12 = 13

x^2 = 1

Square root of 1 = 1

So, x = 1

You can check it by 1+12=13

Answer:

Change two-thirds to a decimal and then multiply the decimal and your number. To convert 2/3 to decimal, divide the numerator by the denominator: 2 / 3 = 0.66666 ... 7, which you can round to 0.67. For example, to find 2/3 of 21: 0.67 * 21 = 14.07.

f ^ - 1 * (x) = log5 x

The factor are (x^2 - 6)(x + 5).

We have given the polynomial of [tex]x^3 + 5x^2 - 6x - 30.[/tex]

The grouping method can be used to factor polynomials whenever a common factor exists between the groupings.

[tex]x^3 + 5x^2 - 6x - 30.[/tex]

factor out the x^2 from first two term and write the remaining term in the bracket

similarly,factor out 6 from the 3rd and 4th term we get

[tex]x^2(x+5)-6(x+5)[/tex]

by grouping are we get

[tex](x^2 - 6)(x + 5).[/tex]

The constant of proportionality for the considered equation is 29.4

Firstly, there is proportional relationship.

Two values [tex]x[/tex] and [tex]y[/tex] are said to be in a proportional relationship if [tex]x=ky[/tex], where [tex]x[/tex] and [tex]y[/tex] are variables and [tex]k[/tex] is a constant.

The constant k is called constant of proportionality.

The proportional relationship between x and y can be written symbolically as

[tex]x \propto y[/tex]

That middle sign is called sign of proportionality.

For the given case, we've got the equation as:

[tex]m = 29.4h[/tex]

Here, m and h are variables.

Thus, using the aforesaid definition, in this equation, the constant of proportionality is  29.4

Step-by-step explanation:

We need to find the demand so the variable x is unknown.

We know that the variable p is 37.55 so we replace that in the equation

[tex]37.55 = 40 - \sqrt{0.01x + 1} [/tex]

Subtract Property

[tex] - 2.45 = - \sqrt{0.01x + 1} [/tex]

Division Property

[tex]2.45 = \sqrt{0.01x + 1} [/tex]

[tex](2.45) {}^{2} = 0.01x + 1[/tex]

[tex]6.0025 = 0.01x + 1[/tex]

[tex]5.0025 = 0.01x[/tex]

[tex]500.25 = x[/tex]

So the answer is about 500 units per day

The angle of depression formed by the cable is 44°.

The angle of depression is an angle measured downward from a horizontal line to the line of sight between an observer and a point that is below the observer. It is used to describe the angle formed between a horizontal reference line (usually the observer's line of sight) and a line drawn from the observer's eye to a point of interest that is lower in elevation.

According to the question the tower, cable, and path makes a triangle whose

base = 350 feet,

hypotenuse = 500 feet.

Since, cos[tex]\theta[/tex] = [tex]\frac{base}{hypotenuse}[/tex]

                  = [tex]\frac{350}{500}[/tex]

                  = [tex]\frac{7}{10}[/tex]

[tex]\theta[/tex] = arccos([tex]\frac{7}{10}[/tex])

 = 0.77539749 radians

 = 0.77539749 × [tex]\frac{180^o}{\pi}[/tex]

 = 0.77539749 × [tex]\frac{180^o}{3.14}[/tex]

 = 44.45°

 ≈ 44°.

Thus, the correct answer is C. 44°.

Because, she deviates by 5, whereas Isabella only deviates by 2. Therefore, Hannah is relatively younger according the mean age of the degree level.

Danielle spent three times as much on transportation as she did on lunch, so we can call this 3x.

She spent $4 less than on books than she did on transportation -> 3x - 4

So, she spent x + 3x + 3x - 4 (simplified as 7x - 4).

Danielle had $59 to spend last week -> 7x - 4 = 59
Solve for x : (59+4)/7 = 9

So, she can spend at max $9 on lunch


Recheck : 9 + 27 + 27 - 4 = 63 - 4 = 59.

[tex]3 * (x - 5)\\3 - 5 = 2\\2 * 3 = 6[/tex]

Answer:

3821.9 [cm³].

Step-by-step explanation:

1) the required volume can be calculated as:

V=V(prism)-V(cylinder);

2) V(prism)=32*12*11=4224 [cm³];

3) V(cylinder)=π*r²*32=3.1415*4*32≈402.1 [cm³];

4) finally, V=4224-402.1=3821.9 [cm³].

Answer:

3,822.08 cm2

Step-by-step explanation:

You would start off by finding the volume of the who post which is 4,224. You then would find the volume of the hole cut out which is 401.92. Then you would subtract 401.92 from 4,224 giving you 3,822.08.
