Answer:

x=10.4

Step-by-step explanation:

well 20*5=what? 20*5=100 but then x would have to be a decimal. not a tough one though.

10*x (x being 10) 10*10 would be 100 but then you would have to subtract 4 from it. it's easy. 10 *10.4 is 104.

x would = 10.4 to get this result

Answer: 7/10

Step-by-step explanation:

Number of people surveyed = 60

Number of people who responded Yes = 42

The relative frequency will be the fraction of those who responded yes divided by the total people surveyed. This will be:

= 42/60

= 7/10.

The relative frequency is 7/10.

Answer:

cos A = 24/51

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

Cos theta = adj side/ hypotenuse

cos A = 24/51

Step-by-step explanation:

We know that cosA=Base/hypontenuse

➡CosA=24/51

This is a right angle triangle

Cos theta=Base/hypontenuse

Given:

ST || RU

To find:

The measure of QS.

Solution:

In triangle QRU and QST,

[tex]\angle RQU\cong \angle SQT[/tex]              [Common angle]

[tex]\angle QRU\cong \angle QST[/tex]              [Corresponding angle]

[tex]\triangle RQU\sim \triangle SQT[/tex]              [AA property of similarity]

The corresponding sides of similar triangles are proportional.

[tex]\dfrac{QR}{QS}=\dfrac{QU}{QT}[/tex]

[tex]\dfrac{23}{QS}=\dfrac{25}{25+50}[/tex]

[tex]\dfrac{23}{QS}=\dfrac{25}{75}[/tex]

[tex]\dfrac{23}{QS}=\dfrac{1}{3}[/tex]

On cross multiplication, we get

[tex]3(23)=1(QS)[/tex]

[tex]69=QS[/tex]

Therefore, the measure of QS is 69.

Answer:

La razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]

Step-by-step explanation:

En el club de teatro asistieron 15 alumnos a clases. En total, son 21 alumnos. Entonces la cantidad de alumnos ausentes se calcula como la diferencia entre la cantidad total de alumnos y la cantidad de asistentes, esto es:

21 alumnos - 15 alumnos= 6 alumnos

La cantidad de alumnos ausentes es 6.

La razón es la comparación de dos cantidades y se mide como el cociente entre dos números o cantidades comparables entre sí, que se expresa como una fracción. Es decir, la razón entre 2 números a y b es el cociente [tex]\frac{a}{b}[/tex].

Entonces, la razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]

Answer:

angle x= 38 degrees

Step-by-step explanation:

Supplementary angles are equal to 180 degrees. We know angle y is equal to 142 degrees. Therefore, the equation is 180-142 which is equal to 38. Angle x is equal to 38 degrees.

Answer:

C = 18

Step-by-step explanation:

There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what is C is in simplest radical form

Solution:

A triangle is a shape with three sides and three angles. Types of triangle are right angled, isosceles, scalene, obtuse, acute.

The length of the side in a triangle is directly proportional to the opposite angle (angle facing the side).

A right angled triangle is a triangle with one angle equals to 90 degrees.

Since the shortest line is 9, the angle facing the shortest line is the smallest angle. The longest line is the hypotenuse which is given as C. Trigonometric identities shows the relationship between the sides of a triangle and its angles, hence:

sin30 = 9 / C

0.5 = 9 / C

C = 9/0.5

C = 18

Answer:

Step-by-step explanation:

Since,

It's a rectangle so it will be formed on the coordinate which is 3units above dot(3,5) in picture where above the dot there is no point .

Answer:

Para un punto (x, y), el angulo generado entre el eje x y un rayo que conecta el origen de coordenadas con el punto es tal que:

Tan(θ) = y/x

Cos(θ) = x/(√(x^2 + y^2))

Sin(θ) = y/(√(x^2 + y^2))

Y las otras 3 relaciones trigonometricas son las inversas de las de arriba, entonces:

Ctg(θ) = x/y

Sec(θ) = √(x^2 + y^2)/x

Csc(θ) = √(x^2 + y^2)/y

En este caso tenemos el punto (4, -3), es decir:

x = 4

y = -3

Solo tenemos que reemplazar esos dos valores en las seis ecuaciones de arriba:

Tan(θ) = -3/4

Cos(θ) = 4/(√(4^2 + (-3)^2)) = 4/5

Sin(θ) = -3/(√(4^2 + (-3)^2)) = -3/5

Ctg(θ) = 4/(-3) = -4/3

Sec(θ) =  √(4^2 + (-3)^2)/4 = 5/4

Csc(θ) = √(4^2 + (-3)^2)/-3 = 5/-3 = -5/3

Omggg twins I'm doing the Iready too:> Anyway I had that question and I selected 1.62

The average rate of change of function [tex]y= \sqrt[3\\]{x}[/tex] over interval [2,7] to rounding to nearest hundredth is 0.13

The Correct option is (b)

The Average Rate of Change function is defined as the average rate at which one quantity is changing with respect to something else changing.

i.e.,  [tex]\frac{f(b)- f(a)}{b-a}[/tex]

It  has been asked in the question the average rate of function over interval [2,7].

The values are given in the table.

So, the rate of change of f(x) on interval [a, b] = [tex]\frac{f(b)- f(a)}{b-a}[/tex]

we have, a=2 and b=7

Thus, [tex]\frac{f(b)- f(a)}{b-a}[/tex] =  [tex]\frac{\sqrt[3]{7} -\sqrt[3]{2} }{7-2} {[/tex]

                       =[tex]-\frac{\sqrt[3]{2} }{5}+\frac{\sqrt[3]{7} }{5}[/tex]

                       =0.1306

                       ≈ 0.13 (rounding off nearest hundredth)

Answer:

144.44 yards

Step-by-step explanation:

The formula to find circumference is: C = π · d

Since we already have most of the factors figured out, we just replace them with what we have.

C = 3.14 · 46 yrds

144.44 = 3.14 · 46
