Find the value of x in the triangle shown below.

Answer:

2:8 is the ratio to an equal ratio

What we were given:

40% of the student in a class are female. if there are 10 females in the class, how many males are there in the class

Answer:

15 males

The total no. of males in a class is 15.

To find the no. of males.

science that deals with the addition, subtraction, multiplication, and division of numbers and properties and manipulation of numbers.

Given that:

If females are 40% , % of males =100-40=60%.

Let the total no. of students be x.

No. of girls = 40% of x

10= (40/100) * x

x=(10*100)/40

x= 25

total no. of students =25

Total no. of males = 60% of x

=(60/100)* 25

=15

So, total no. of males in a class is 15.

Answer:

To find the circumference

diameter x 3.14 = circumference

We can undo the multiplication and divide to get the diameter

37.68 /3.14 = 12

diameter / 2= radius

12 / 2 = 6

the radius is 6

radius x radius x pi = area

6 x 6 x 3.14 = 113.04

113.04 is the answer

Hope this helps

Step-by-step explanation:

Answer:

113.04 square inches.

Step-by-step explanation:

The formula to find the circumference is 2πr. The formula for the area is πr^2. We are trying to find r in order to solve the problem.

It says use 3.14 for π. The circumference is 37.68 inches.

2πr = 37.68

2 * 3.14r = 37.68

3.14r = 18.84

r = 6

Now that we know the radius of the circle, we can find the area!

πr^2 = 3.14 * (6^2) = 3.14 * 36 = 113.04.

Answer:

85.33333

Step-by-step explanation:

You would simply substitute 4 whenever there is an x.

f(4) = (1/3) * 4^4

= (1/3) * 16 * 16

= (1/3) * 256

= 256/3

= 85.3333333333333333333333333333333333333

which is about 85.3333, or 85 and 1/3, or 256/3.

Answer:

h=3V/πr²

Step-by-step explanation:

Answer:

3V / (pi r^2) =  h

Step-by-step explanation:

V= pi r squared h/3

Multiply each side by 3

3V = pi r^2 h /3  * 3

3V = pi r^2 h

Divide each side by pi r^2

3V / (pi r^2) = pi r^2 h /( pi r^2)

3V / (pi r^2) =  h

# of SALE - - - 5 - - 8 - - - 2 - - 19 - 22 - 15 - - 3

# of restock - 6 - - 12 - - 12 - - 18 - 24 - 0 - - 0

Calculating the change in shelf unit on a daily basis:

Change = difference in restock unit and the unit sold, that is, # RESTOCK - # SOLD

TUESDAY :

6 - 5 = 1

WEDNESDAY :

12 - 8 = 4

THURSDAY :

12 - 2 = 10

FRIDAY :

18 - 19 = - 1

SATURDAY :

24 - 22 = 2

SUNDAY :

0 - 15 = - 15

MONDAY :

0 - 3 = - 3

The net change equals the algebraic sum of all daily changes in shelf unit between Tuesday to Monday ;

[1 + 4 + 10 + (-1) + 2 + (-15) + (-3)]

[1 + 4 + 10 - 1 + 2 - 15 - 3]

[ 1 + 4 + 10 + 2 - 1 - 15 - 3]

Answer:

El tiempo le llevara a Mariano es 2 horas y el tiempo que le llevara a Alberto es de una hora

Step-by-step explanation:

Para calcular el tiempo que le llevará a cada uno si juntos pueden hacer el trabajo en 3h, tenemos que primero segun los datos considerar lo siguiente:

Segun los datos tenemos que Mariano puede despachar periódicos 2 veces el tiempo que le toma a Alberto, por lo tanto:

2X=Mariano puede despachar periódicos 2 veces el tiempo que le toma a Alberto

X=El tiempo que le toma a Alberto.

Por lo tanto calculando la siguiente ecuacion, podremos hallar el valor de X:

2X+X=3 horas

3X=3 horas

X=1 hora

Entonces, tenemos que el tiempo le llevara a Mariano es 2 horas y el tiempo que le llevara a Alberto es de una hora

Answer:

∠BAD = 100°

∠ADC = 105°

∠DCB = 50°

∠ABC = 105°

Step-by-step explanation:

∠BAD is given.

∠ADC is supplementary to the 75°, so it is 180-75 = 105°

∠DCB is 50° just like its opposite angle

The sum of all angles in a quadrilateral must be 360, so ∠ABC = 360-100-105-50 = 105.

Explanation:

The expression -2x means -2 times x. To undo this, we divide all parts of the inequality by -2. Dividing by a negative number will flip the inequality sign. We go from "less than" to "greater than"

-4 < -2x < 10

-4/(-2) > x > 10/(-2) .... inequality signs flip

2 > x > -5

-5 < x < 2

This unknown number x is between -5 and 2. It cannot equal -5. It cannot equal 2.

Answer:

125°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 8 (octagon), thus

sum = 180° × 6 = 1080°

let x represent one of the equal angles, then

3x + 705 = 1080 ( subtract 705 from both sides )

3x = 375 ( divide both sides by 3 )

x = 125

Thus the size of one equal angle = 125°

Answer:

[tex]\frac{b+a}{b-a}[/tex]

Step-by-step explanation:

Tan θ = [tex]\frac{perpendicular}{base}[/tex] = [tex]\frac{b}{a}[/tex]

So, Perpendicular = b, base = a

Finding hypotenuse by Pythagorean Theorem:

[tex]c^2 = a^2+b^2[/tex]

=> So, hypotenuse = c

Sin θ = [tex]\frac{perpendicular}{hypotenuse}= \frac{b}{c}[/tex]

Cos θ = [tex]\frac{base}{hypotenuse}= \frac{a}{c}[/tex]

So, Now finding [tex]\frac{sin\theta+cos\theta}{sin\theta-cos\theta}[/tex]

=> [tex]\frac{b}{c} + \frac{a}{c}[/tex] ÷ [tex]\frac{b}{c} - \frac{a}{c}[/tex]

=> [tex]\frac{b+a}{c}[/tex] ÷ [tex]\frac{b-a}{c}[/tex]

=> [tex]\frac{b+a}{c} * \frac{c}{b-a}[/tex]

=> [tex]\frac{b+a}{b-a}[/tex]
