Solution:

☯ Let number of girls be x.

Given that,

Therefore,

→ 12/x = 4/5

→ x = 12 × 5/4

→ x = 60/4

→ x = 15

∴ Hence, number of girls in a class is 15.

The length DC of the triangle ΔBDC using the trigonometric function will be 30.43 units.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The length of BD is given as,

sin A = BD / AB

sin 54° = BD / 20

BD = 20 × sin 54°

Then the length of DC is given as,

tan C = BD / DC

tan 28° = (20 × sin 54°) / DC

DC = (20 × sin 54°) / tan 28°

DC = 20 × 1.5215

DC = 30.43 units

The length DC of the triangle ΔBDC using the trigonometric function will be 30.43 units.

Answer: I don't understand either :{

But I do know that you have to look at the little letters to answer the questions about the triangle. Like when it asks, "What are the possible values for x?" you have to find x then say what the possible values for x are. Hope that helps a little bit

Answer:

x = 15

Therefore, the length and width are 31 and 47.

Step-by-step explanation:

Perimeter = (2x + 1) + (2x + 1) + (3x + 2) + (3x + 2) = 156

Simplified,

10x + 6 = 156

Subtract 6 from both sides, then divide by 10.

10x = 150

x = 15

To find the length and width, substitute 15 (the value of x) into the individual equations.

2(15) + 1 = 31

3(15) + 2 = 47

An equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

Given the equation

[tex]6x+y=6[/tex]

Writing in the slope-intercept form of the line equation

[tex]y = -6x + 6[/tex]

comparing with the slope-intercept form of the line equation

y = mx+b

Thus, the slope of line = m = -6

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line is also -6.

As the line passes through the point (2,−5).

Thus, using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope and (x₁, x₂) is the point

substituting the values m = -6 and the point (2,−5)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - (-5) = -6 (x - 2)[/tex]

[tex]y+5=-6\left(x-2\right)[/tex]

subtract 5 from both sides

[tex]y+5-5=-6\left(x-2\right)-5[/tex]

[tex]y=-6x+7[/tex]

Therefore, an equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

Answer:

The answer is C.

Step-by-step explanation:

First, you have to find the interest amount after 6 years. In order to do this, you have to subtract :

[tex]3967.50 - 3450 = 517.50[/tex]

Next, you have to apply simple interest formula, I = (P×R×T)/100 where I repesents interest amount, P is priciple, R is interest rate and T is number of years :

[tex]i = \frac{prt}{100} [/tex]

[tex]let \: i = 517.50,p = 3450,t = 6[/tex]

[tex]517.50 = \frac{3450 \times r \times 6}{100} [/tex]

[tex]517.50 = \frac{20700r}{100} [/tex]

[tex]51750 = 20700r[/tex]

[tex] \frac{51750}{20700} = r[/tex]

[tex]r = 2.5\%[/tex]

We need to solve both for y.

#9:

[tex]y - 4 = 3(x - 1)\\\\y - 4 = 3x - 3\\\\y = 3x + 1[/tex]

#10:

[tex]y - 1 = -4[x - (-3)]\\\\y - 1 = -4(x + 3)\\\\y - 1 = -4x - 12\\\\y = -4x - 11[/tex]

Now let's look at an example using the formula for the volume of a cylinder. ... is V = πr2h, where V is the volume, r is the radius and h is the height of the cylinder

If r represents the radius of a cylinder then 2πr³ can represent D. the lateral area of a cylinder whose height and radius are equal.

A cylinder is a three-dimensional solid object with two bases that are identically circular and are connected by a curving surface that is located at a specific height from the center.

Examples of cylinders are toilet paper rolls and cold beverage cans.

The volume of a cylinder is πr²h.

Lateral surface area = 2πrh.

Total surface area = 2πr(h + r).

Given, r represents the radius of a cylinder.

The expression 2πr³ can represent the lateral surface area of a cylinder whose height and radius are equal.

The lateral surface or curved surface area of a cylinder is 2πrh.

The algebraic expression -5x+6y-3/x is not a polynomial.

The given polynomials are 7-z, 2p³q²-pq³ and -5x+6y-3/x.

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.

Here,

In 7-z has non-negative integer as exponent

So, it is a polynomial

In 2p³q²-pq³ has non-negative integer as exponent

So, it is a polynomial

In -5x+6y-3/x has negative integer as exponent, which is [tex]x^{-1}[/tex]

So, it is not a polynomial

Hence, the algebraic expression -5x+6y-3/x is not a polynomial.
