Answer:

The amount Nlda receives = Rs. 49

The amount her brother receives = Rs. 21

Step-by-step explanation:

Ratio of their ages

Nlda : Her brother

7:3

Sum of proportion = 7 + 3 = 10

Amount of money to the shared = Rs.70

The amount Nlda receives = 7/10 × Rs. 70 = Rs. 49

The amount her brother receives =

3/10 × Rs. 70 = Rs. 21

Answer:

224

Step-by-step explanation:

Hello!

To find f(-7) you simply plug the value, -7, into the function.

This will get you:

f(-7) = 4(-7)^2 - 4(-7)

Remember that the square of a negative number is a positive! Also, remember to use the order of operations (PEMDAS)!

This will get you:

f(-7) = 4(49) - 4(-7)

f(-7) = 196 - (-28)

f(-7) = 224

Hope this helps!

Answer:

El cuestionario puede ser respondido de 360 formas diferentes.

Step-by-step explanation:

Dado que un político envía un cuestionario a sus votantes para determinar sus intereses acerca de 6 asuntos de importancia nacional: desempleo, medio ambiente, impuestos, tasas de interés, defensa nacional y seguridad social, y los votantes deben seleccionar cuatro asuntos de interés personal y colocarlos en orden 1, 2, 3 y 4 después de cada asunto para indicar el grado de interés, donde 1 indica el mayor interés y 4 el menor interés, para determinar en cuantas formas se puede responder al cuestionario se deben realizar los siguientes cálculos:

6 x 5 x 4 x 3 = X

30 x 4 x 3 = X

120 x 3 = X

360 = X

Por lo tanto, el cuestionario puede ser respondido de 360 formas diferentes.

Answer:

Work done = 150 x 5  = 750 J

Step-by-step explanation:

Work done is the measure of energy transferred to an object when a force is added causing the object to move a distance in the direction of the force.

The equation for work done is force time the distance and is measured in Joules. Therefore the formula is W = F x D

work done (W) is measured in joules (J)

force (F) is measured in newtons (N)

distance (d) is in the same direction as the force and is measured in

metres (m)

W = F x D

w = 150 x 5

W = 750 J

Answer:

JL = 68

Step-by-step explanation:

JM = ML

Hence, 3x + 4 = 5x - 16

Subtract 3x from both sides

4 = 2x - 16

Add 16 to both sides

20 = 2x

Divide both sides by 2

10 = x

Now we want to find JL

Note that JL = JM + ML

JM = 3x + 4 and x = 10

Substitute 10 for x

3(10) + 4

Multiply

30 + 4

Add

JM = 34

Because JM = ML

We simply multiply 34 times 2 to find the length of JL

34 * 2 = 68

JL = 68

Answer: [tex]\dfrac{\sqrt{2}}{2}[/tex]

Step-by-step explanation:

Given

The fraction is [tex]\dfrac{2}{2\sqrt{2}}[/tex]

Making denominator a number, multiply and divide by [tex]\sqrt{2}[/tex]

[tex]\Rightarrow \dfrac{2}{2\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}\\\\\Rightarrow \dfrac{2\sqrt{2}}{2\sqrt{2}\times \sqrt{2}}=\dfrac{2\sqrt{2}}{2\sqrt{2\times 2}}\\\\\text{cancel out the common term 2}\\\\\Rightarrow \dfrac{\sqrt{2}}{2}[/tex]

Answer:

112.03sq. units

Step-by-step explanation:

The area of a sector = theta/360 * πr²

The area of a sector = 76/360 * 3.14 * 13²

The area of a sector = 76/360 * 530.66

The area of a sector = 40,330.16/360

The area of a sector = 112.03sq. units

This gives the area of the sector

Answer:

20 sin³O. cos²O - 5sin⁵O

Step-by-step explanation:

y = sin⁵O

Using the Chain Rule

dy/dO = 5 sin⁴O cosO

Using the Product / Chain rules:

d²y/dO² = 20 sin³O.cosO . cos O+ 5 sin⁴O * - sin O

= 20 sin³O. cos²O - 5sin⁵O

The density of golf ball is 0.000113 gm/mm³

What is volume ?

Volume is a three dimensional space occupy by the body of particular shape such as here :

volume (V) of sphere with radius r : 4πr³/3

it is given that :

golf ball has a diameter d of = 42.67 millimeters

r = d/2 = 21.33 mm

golf ball has a mass m of = 45.93 grams

First, let us find the volume of the golf ball can be determined using the formula:

V = 4πr³/3

Substituting r = 21.33mm, we get;

V = 4π(21.33)³/3

V = 40650 mm³

Now, to find the number of grams per cubic millimeter of the material used to make the golf ball we find the density of golf ball :

ρ = m/V

ρ = 45.93/40650

ρ = 0.000113 gm/mm³

Therefore, the density of golf ball is 0.000113 gm/mm³

Answer:

1/ 3^6

Step-by-step explanation:

We know that a^b / a^c = a^(b-c)

3^-7 / 3^-1 = 3^(-7 - -1) = 3^(-7+1) = 3^(-6)

We know that a^ -b = 1/ a^b

3^-6 = 1/ 3^6

Answer:

Quadrant III

Step-by-step explanation:

-180° is a 180° rotation clockwise, which will end up between Quadrant II and III. -90° is a 90° rotation clockwise, which will end up between Quadrant III and Quadrant IV. The range of possible angles are contained in Quadrant III, in conclusion.

Answer:

0.5x+20=0.25x+30, m=40

Step-by-step explanation:

Blue: y=0.5x+20

Red: y=0.25+30

We’re looking for where the y (cost) is equal, so we can set the two equations to each other:

Isolate x:

0.5x+20=0.25x+30

0.5x+20-20=0.25x+30-20

0.5x=0.25x+10

0.5x-0.25x=0.25x+10-0.25x

0.25x=10

x=40

m= 40

x - 17 = 28

so

28 + 17 = x

28 + 17 = $45

so

x = $45

(I'm pretty sure)
