9514 1404 393

Answer:

Step-by-step explanation:

A solution is always of the form ...

  variable = something

In order to get this form, the variable needs to be isolated (put by itself on one side of the equal sign).

In general, isolating the variable involves using inverse operations to "undo" whatever is done to the variable. These are generally applied in the reverse order of the operations that are done to the variable. The list of operations done and their order can be identified using the Order of Operations to consider how an equation would be evaluated for some value of the variable.

Answer:

2.719 minutes

Step-by-step explanation:

Step 1 :

We have to consider using the M/G/I /GD /∞/∞ Queuing system with the rate of arrival λ and the rate of service μ.

Since average of 40 cars arrive every hour at the painting facility, it follows that:

Arrival rate λ = 40cars /hour

= 40/60 cars/hour

=2/3 cars/hour

More, we were told that 95% of the cars require 1 minute to paint, 5% must be painted twice and require 2.5 minutes to paint, therefore, the average time to paint a car is given by

95/100x1 + 5/100 x 2.5 = 19/20 + 1/8 = 43/40min

It follows that:

Service rates μ = 40/43cars/min

Answer:

2=414x-4+18

2=414x+14

2-14=414x

-12=414x

-12/414=x

Step-by-step explanation:

Answer:

2x-5x-24=0

-3x-24=0

-3x=24

x=24/-3

x=-8

Answer:

x=x2-24/5

2 −24

​

Step-by-step explanation:

x2−5x−24=0

Add 5x to both sides. Anything plus zero gives itself.

x

2

​

−24=5x

Add 24 to both sides.

x

2

​

=5x+24

Answer:

x = 37

Step-by-step explanation:

Well if you didn't know vertical angles are congruent ( or equal to each other )

Which means that 74 = 2x

If we want to find the value of x, then we need to get rid of the "2" on 2x

To do so we can divide each side by 2

74 / 2 = 37

2x / 2 = x

we would be left with x = 37

Answer:

About 400 times

Step-by-step explanation:

Given

[tex]n = 1060[/tex]

See attachment for spinner

Required

Determine the number of times an outcome of 1, 3 or 8 is expected

First, calculate the theoretical probability of 1, 3, or 8

This is calculated as:

[tex]Pr = P(1) + P(3) + P(8)[/tex]

The spinner is divided into 8 equal segments and each outcome appears once.

So, we have:

[tex]Pr = \frac{1}{8}+\frac{1}{8}+\frac{1}{8}[/tex]

Take LCM and add

[tex]Pr = \frac{1+1+1}{8}[/tex]

[tex]Pr = \frac{3}{8}[/tex]

So, the expected number of times (E) is:

[tex]E = Pr * n[/tex]

[tex]E = \frac{3}{8} * 1060[/tex]

[tex]E = \frac{3* 1060}{8}[/tex]

[tex]E = \frac{3180}{8}[/tex]

[tex]E = 397.5[/tex]

Approximate

[tex]E = 398[/tex]

This means about 400 times

Answer:

120 000 centimeters

Step-by-step explanation:

Answer:

120,000 cm³

Step-by-step explanation:

Given :-

And we need to find the volume of the hay . The hay is in the form of cuboid .We know that the volume of a cuboid is ,

[tex]:\implies[/tex] Volume = l × b × h

[tex]:\implies[/tex] Volume = 100cm*40cm*30cm

[tex]:\implies[/tex] Volume = 1,20,000 cm³

Answer:

[tex]\theta=36.43^{\circ}[/tex]

Step-by-step explanation:

Given that,

Base = 42

Perpendicular height = 31

We need to find the value of [tex]\theta[/tex]. It can be calculated using trigonometry as follows :

[tex]\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})[/tex]

Put all the values,

[tex]\theta=\tan^{-1}(\dfrac{31}{42})\\\\\theta=36.43^{\circ}[/tex]

So, the value of [tex]\theta=36.43^{\circ}[/tex].

I may be wrong-

Answer:

Step-by-step explanation:

Answer:

33.3 cm²

Step-by-step explanation:

Recall: Area Scale Factor = (Linear Scale Factor)²

Area scale factor = surface area of bigger cone/surface area of smaller cone

Let the surface area of the smaller cone be represented as x

Therefore,

Area scale factor = 75/x

Linear scale factor = radius of bigger cone/radius of smaller cone = 3/2

Thus:

75/x = (3/2)²

75/x = 9/4

Cross multiply

x*9 = 75*4

9x = 300

Divide both sides by 9

x = 300/9

x = 33.3 cm² (nearest tenth)

Answer:

[tex]\frac{8}{10} =\frac{4}{5}[/tex]

Step-by-step explanation:

Both the numerator and denominator of the fraction [tex]\frac{8}{10}[/tex] share a common factor of 2, so you can divide the fraction by [tex]\frac{2}{2}[/tex](1). This leaves you with:

[tex]\frac{8}{10}[/tex] ÷ [tex]\frac{2}{2}[/tex] = [tex]\frac{4}{5}[/tex]

This means that the fraction [tex]\frac{8}{10} =\frac{4}{5}[/tex].

Answer:

  y = x + 2

Step-by-step explanation:

The slope-intercept form equation is ...

  y = mx + b . . . . . . slope m, y-intercept b

We are given the slope, so we only need to find the y-intercept. When we solve for b, we find ...

  y - mx = b . . . . . .  subtract mx

  8 - 1(6) = b = 2 . . . . fill in given values of (x, y) and m

Then the equation of the line is ...

  y = x +2

Answer: D (64)

Step-by-step explanation:

My answer is correct because, it's showing that 4 is the length, width, and height. So it bassically 4 x 4 x 4 in other words 4 exponent 3. And 4 exponent 3 would equal 64.

Answer:

B. No; measure of interior angle = 144

Step-by-step explanation:

I calculated it logically

The solution is, The area of the shaded region is 112cm^2.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

First find the area of the rectangle

A = l*w

= 9*16

= 144

The unshaded area is a trapezoid

A = 1/2 ( b1+b2) *h

= 1/2 ( 5+11) * 4

= 1/2 (16) * 4

=32

The area of the shaded region is

rectangle - trapezoid

144-32

112cm^2

Hence, The solution is, The area of the shaded region is 112cm^2.

Answer:

5 × 4 = 20 not 40

Step-by-step explanation:

Hello there I hop you are having a good day :)

So, if she brought 2 tickets an they cost £4.00 you would add £4.00 + £4.00 = £8.00 and then you would take that away from the £10.00 - £8.00 = £2.00 so Emma would get £2.00 change :) hopefully that helps you.

Answer:

  (x, y) = (-1/2, 3/4)

Step-by-step explanation:

A graphing calculator does a nice job of finding the solution.

  (x, y) = (-1/2, 3/4)

__

You can eliminate y by adding twice the second equation to the first.

  (2x +8y) +2(24x -4y) = (5) +2(-15)

  50x = -25

  x = -1/2 . . . . . . divide by 50

__

  24(-1/2) -4y = -15 . . . . .substitute for x in the second equation

  -4y = -3 . . . . . . . . . add 12

  y = 3/4 . . . . . . . . . divide by the coefficient of y

The solution is (x, y) = (-1/2, 3/4).

Step-by-step explanation:

Experimental - 5 choices, 1 is Q = 1/5

Theoretical - 5 choices, landed on Q 4 times =4/5

Answer:

Probability of getting all three correct answer =  [tex]\frac{1}{64}[/tex]

Step-by-step explanation:

Given - A multiple choice test contains questions  with four options each: A, B, C, or D. If  Natalie randomly guesses on the last three  questions.

To find - what is the probability that she  gets all three correct.

Proof -

Given that,  question has 4 options.

And 1 option can be correct,

Let

x be that Natalie gives correct answer.

So,

Probability of getting, correct answer, P(x) = [tex]\frac{1}{4}[/tex]

So,

Probability of getting, incorrect answer, P(x') = 1 -  [tex]\frac{1}{4}[/tex] = [tex]\frac{3}{4}[/tex]

Now,

Given that, she guess the 3 questions.

All correct means,

first, second, third question answer is correct.

So,

Probability of getting all three correct answer = [tex]\frac{1}{4}[/tex]×[tex]\frac{1}{4}[/tex]×[tex]\frac{1}{4}[/tex] = [tex]\frac{1}{64}[/tex]
