Answer:

90

Step-by-step explanation:

180/2=90

Answer:

22

Step-by-step explanation:

f(3) = 7(3-1) + 8

f(3) = 7(2) +8

f(3) = 14 + 8

f(3) = 22

Answer:

f(3) = 22

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x), that is

f(3) = 7(3 - 1) + 8

     = 7(2) + 8

     = 14 + 8

     = 22

Step-by-step explanation:

the 7cm and the 3cm is 21 cm^2                                                                           the 4cm and the 5cm is 20cm^2                                          

the 11cm and the 2cm is 22cm^2                                                                    

basically if your looking for the largest area then the 11cm and the 2 cm is your answer.

hope this helps

336.752÷31= 10.86296774

And round it to the nearest ten which is 10.9

Step-by-step explanation:

let y = f(x)

82 = x^2 + 1

81 = x^2

x = ±9

y = (3)^2 + 1

y = 10

26 = x^2 + 1

25 = x^2

Answer:

(-5, -10)

Step-by-step explanation:

(5, -10) is in quadrant 4.

When it reflects on the y-axis, it lands in quadrant 3.

Quadrant 3 is all negative coordinates.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

Reflected along the y-axis from IV Quadrant to II Quadrant

The coordinate will change using the form as,

(x, -y) → (-x, -y)

The coordinate of the reflected point is (-5, -10)

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Coordinates = (5, -10)

This is in IV Quadrant

If it is reflected across the y-axis.

(5, -10) will be in the III Quadrant.

Now,

The y-coordinate will remain the same but the x-coordinate will change its sign.

The coordinate will change using the form as,

(x, -y) → (-x, -y)

(5, -10) → (-5, -10)

Thus,

The coordinates of the reflected point is (-5, -10)

The question is missing some parts. Here is the complete question.

The random variable X takes on the values of 2, 5, n and 15. The probability distribution of X is shown in the table below.

The expected value of X is 9.1. What is the value of n?

a) 8

b) 8.52

c) 10

d) 12

e) 14.4

Answer: d) 12

Step-by-step explanation: In a probability distribution, Expected Value is the average (or mean) value a distribution can assume.

The Expected Value, E(X), can be determine by:

[tex]E(X)=\Sigma xP(x)[/tex]

in which

x is how many times an event happens

P(x) is the probability of an event happening

The table below n is x and expected value is 9.1, then:

[tex]9.1=2*0.1+5*0.4+0.2n+15*0.3[/tex]

[tex]9.1=0.2n+6.7[/tex]

[tex]0.2n=2.4[/tex]

n = 12

Value of n in this probability distribution is 12.

The value of n in the discrete probability distribution given is 12.

The the sum of [P(X) × X] in a discrete probability distribution is the expected value

From the discrete probability table given :

P(X) × X can be expressed as :

(0.1 × 2) + (5 × 0.4) + (15×0.3) + 0.2n = 9.1

0.2 + 2.0 + 4.5 + 0.2n = 9.1

6.7 + 0.2n = 9.1

0.2n = 9.1 - 6.7

0.2n = 2.4

n = 2.4 / 0.2

n = 12

Therefore, the value of n in the table is 12

This is equivalent to equivalent to 2 hours, 30 minutes.

======================================================

Work Shown:

1/3 of the house = 50 minutes

3*(1/3 of the house) = 3*(50 minutes)

3/3 of the house = 150 minutes

1 house = 150 minutes

-----------

Sam will need 150 minutes to clean the whole house

Divide this over 60 to convert to hours

150 minutes = (150/60) hours

150 minutes = 2.5 hours which is the final answer

-----------

Or you could say the following

150 minutes = 120 min + 30 min

150 minutes = (120/60) hr + 30 min

150 minutes = 2 hr + 30 min

This shows that 2.5 hours is equivalent to 2 hours, 30 minutes.

Answer:

El dinero que recibió Armando no es suficiente porque recibió $135.000 y tiene que pagar $142.000.

Step-by-step explanation:

Primero, tienes que sumar los gastos para encontrar la cantidad que Armando tiene que pagar:

47.550+69.700+24.750=$142.000

De acuerdo a esto, el total a pagar es $142.000 y Armando recibió $135.000 por lo cual el dinero que recibió no es suficiente porque el total que tiene que pagar es más alto.

Answer:

54minutes

Step-by-step explanation:

Let the time taken to clean up be t

Let the number of people cleaning be n

If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;

t = k/n

k is the constant of proportionality

If 3 people work together to clean, and took them 90 minutes, this means

at t = 90, n=3

Substitute

90 = k/3

k = 3×90

k = 270

To et the time it will take 5people to clean, the will say;

t =k/n

t =270/5

t = 54 minutes

Hence it will take 5 people 54minues to clean

Answer: 54 minutes

Answer: y=-3/2x-13/2

Step-by-step explanation:

To find a line parallel to the given line, we know that the two equations must have the same slope. We first want to find the slope of the given equation.

3x+2y=9             [subtract both sides by 3x]

2y=-3x+9            [divide both sides by 2]

y=-3/2x+9/2

Now, we know the slope if -3/2. All we have to do is plug in the given point to find the y-intercept.

-5=-3/2(-1)+b      [multiply]

-5=3/2+b            [subtract both sides by 3/2]

b=-13/2

Now, we know the equation is y=-3/2x-13/2.

Step-by-step explanation:

We want to get (r) alone on one side

A=πr^2

divide each side by π

A/π=r^2

square root each side

√(A/π)=r

r=√(A/π) is the answer to your first question.
