Write a function to convert Celsius to Fahrenheit using F=(9/5)C+32. Find the Fahrenheit value when C=56.7 and when C=−89.2. (The record high and low temperatures ever recorded on Earth.)
If x is the given temperature in Celsius, the function to return the equivalent temperature in Fahrenheit it:

f(x) = 9 / 5 * x + 32
f(x) = 9/5x + 32
f(x) = 9/5 * (x + 32)
f(x) = 9/5c + 32

The value in Fahrenheit at C=56.7 (a record high) is:
?

The value in Fahrenheit at C=−89.2 (a record low) is:
?

Using your function, f(C), to convert Celsius to Fahrenheit, compare the difference at C=20 between the function value and the simpler function: g(C)=2C+30. (In other words, is "double and add 30" a reasonable approximation?)

The difference f(C)−g(C) at C=21 (approximate room temperature) is:
?

P=160-70*cos(2π*(1/12)*t)

• Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).

First, we find the amplitude by taking the difference between the peak values and dividing by two:

Amplitude=(230+90)/2=70

We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:

90+70=160

230-70=160

This tells us that the Center Value=160

The frequency that we are operating at is given as:

f = 5/hour

so in minutes

f=5*(1/60)/minute=5/60=1/12 per minute

So, combining everything we get

P=160-70*cos(2π*(1/12)*t)

Step-by-step explanation:

Since the test has twenty-five questions, and Peter got 80% correct...

80/100 = __/25 <--What number is the numerator?

Well, to get from 100 to 25, you have to divide by 4. 100/4 = 25.

Now, what is 80/4? If you do the math, you should get 20.

Answers:

Row 1:      1    3  

Row 2:     2    2

Each single digit gets its own box.

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

Explanation:

Each row of three values must multiply to 12. We see that happening with the first two cuboids.

Cuboid A:  1*1*12 = 12

Cuboid B: 1*2*6 = 12

-------------

For cuboid C, we have two blank spaces multiplied with 4. Let's call these blank spaces x and y. We want to solve the equation x*y*4 = 12.

Divide both sides by 4 and you'll get x*y = 3

Since x and y are positive integers, this must mean either

x = 1 and y = 3

or

x = 3 and y = 1

Those are the only ways to multiply to 3 with two integers. But we can rule out the second case because the instructions say "Put the answers in order of size from left to right". Basically your teacher wants them sorted from smallest to largest. Refer to cuboid B for an example of what I mean.

So this means we have the values: 1, 3, 4 for cuboid C

---------------

Cuboid D is a similar story

Let x and y be the blank spaces. We can see that x*y*3 = 12 which becomes x*y = 4 after dividing both sides by 3.

This time we have three ways to do this and they are

We can immediately rule out x = 4 and y = 1 because we need the answers sorted from smallest to largest.

We can also rule out x = 1 and y = 4 because the sequence 1,4,3 is not fully sorted from smallest to largest. Note how this is effectively a repeat of cuboid C (just in a different order).

The only thing left is x = 2 and y = 2

For cuboid D we have these dimensions: 2, 2, 3

The steps are :

[tex]x + 2y = 13 - - - (1)[/tex]

[tex] - x + y = 5 - - - (2)[/tex]

[tex](1) + (2)[/tex]

[tex]x + 2y + ( - x) + y = 13 + 5[/tex]

[tex]3y = 18[/tex]

[tex]y = 6[/tex]

[tex]substitute \: y = 6 \: into \: (2)[/tex]

[tex](2)⇒[/tex]

[tex] - x + 6 = 5[/tex]

[tex] - x = - 1[/tex]

[tex]x = 1[/tex]

Therefore, you have to insert the values into the coordinates form so the answer willl be (1 , 6).

Answer: simplifying

Step-by-step explanation:

2y + -10 = 6x

Reorder the terms:

-10 + 2y = 6x

Solving

-10 + 2y = 6x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 2y = 10 + 6x

Combine like terms: -10 + 10 = 0

0 + 2y = 10 + 6x

2y = 10 + 6x

Divide each side by '2'.

y = 5 + 3x

Simplifying

y = 5 + 3x

Answer:

0.699733

Step-by-step explanation:

Given that :

Mean (m) = 8

Standard deviation (s) = 0.3

Probability that pH is between 7. 5 and 8.2

Probability of pH < 7.5

P(x < 7.5)

The standardized score (Z) :

Z = (x - m) / s

Z = (7.5 - 8) / 0.3 = - 1.6667

p(Z < - 1.6667) = 0.047787 ( Z probability calculator)

Probability of pH < 8.2

P(x < 8.2)

The standardized score (Z) :

Z = (x - m) / s

Z = (8.2 - 8) / 0.3 = 0.6667

p(Z < 0.6667) = 0.74752 ( Z probability calculator)

Hence,

p(Z < 0.6667) - p(Z < - 1.6667)

0.74752 - 0.047787 = 0.699733

Rajesh own a plot of rectangular shape he has fenced it with a wire of length 750 ft . the length of the plot exceeds the breadth by 5ft.

Given that

To find

So, according to the question

We have,

Let's assume

He fenced this plot with a wire. So we can say this wire length is a perimeter of this plot of rectangular shape.

In mathematical form

           2 (length + breadth) = length of fenced wire

                               2 ( l + x) = W -------------------(1)

From question

                                          l = x +5 ------------------(2)

Now, putting the value of equation (2) and W in equation (1)

Then, we get

                               2 ( l + x) = W -------------------(1)

                      2 [( x + 5) + x] = 750

                        2 [ x + 5 + x] = 750/2

                               [ 2x + 5] = 375

                                        2x = 375-5

                                        2x = 370

                                          x = 370/2

                                          x = 185ft

Now, putting the value of x in equation (2)

Then, we get

                                          l = x +5 ------------------(2)

                                          l = 185 +5

                                          l = 190ft

Answer:

The expected completion time of the project is:

10 days.

Step-by-step explanation:

Duration of Task A = 5 days

Task B and C depend on Task A

This implies that Task A must be completed before Task B and C can be started.

To complete Task B will take 5 days

To complete Task C will take 5 days (7 * 0.5) + (3 * 0.5)

Since Task A takes 5 days and Tasks B and C depend on Task A and Task B takes 5 days and Task C takes expected time of 5 days, it means that the project can be completed in 10 days (5 + 5) if tasks B and C are simultaneously carried out.

The expected completion time of the project is

(i)10 days if B&C are mutually independent

(ii)15 days if B &C are mutually dependent

Expected completion time of a task= p1x1 + p2x2

Where

p1 & p2 are probabilities.

x1 and x2 are samples.

p1=p2=0.5

x1=7

x2=3

Expected completion time of task C= 0.5*7+0.5*3 = 5 days

Task B and C will be due till task A is not accomplished.

Total time to accomplish task A = 5 days

Total time  to accomplish task B= 5 days

Expected time to accomplish task C = 5 days

If tasks B and C are mutually independent

expected time to complete the project = 5+5=10days

If task C depends on task B

Expected time to complete the project = 5+5+5 = 15 days.

Therefore

The expected completion time of the project is

(i)10 days if B&C are mutually independent

(ii)15 days if B and C are mutually dependent

Answer:-5.675

Step-by-step explanation:

Answer:

The answer is -227/40 or -5 27/40

Step-by-step explanation:

Easiest way to explain this is to first get the common denominator of the denominators of 5 and 8

This will equal 40 and we have to multiply the numerators as well so this will look like....

-35/40 - 4 32/40

Now we need to convert the whole number in -4 32/40 into a fraction

4 multiplied by 40 is 160 so we will need to add 160 and 32 making the equation now say -35/40 -192/40 which will equal -227/40

So this will make the answer -227/40 in fraction form and in a compound fraction it will be -5 27/40

Answer:

71 /84

answer is not in imporper fraction.

Step-by-step explanation:

fractions need to be changed or converted to equivalent fractions inorder to solve them.

1.Total amount of cherries he bought and he already had in cupboard= 3/7 + 2/3

convert them to equivalent fractions inorder to add them by using LCM of the denominators.Which in this case is 21 (LCM of 7 and 3 is 21)

2. Now the common denominator is 21

change 3/7 to a fraction with 21 as denominator by multiplying the numerator to 3 and denominator also by 3 which will give you 3×3=9/ 7×3=21 or 9/21

note: you have to multiply both numerator and denominator by the same number which is used to convert the denominator to the number given by LCM.

3)Now change the second fractions denominator to 21 by multiplying the denominator 3 by 7 and numerator 2 to 7 :

2×7/3×7 = 14/21

4) Now the fractions have same denominator which means they can be added or subtracted.

5) Total amount of cherries he had= 9/21+14/21 = 23/21

6) The amount of cherries he ate = 1/4

7) Amount of cherries he has now with him after he ate 1/4 from 23/21 = 23/21 - 1/4

8) Again the fractions need to be changed to equivalent fractions inorder to subtract them.So,Take the LCM of the denominators (LCM 21 and 4 is 84).Now change the denominator of each fraction to 84.

9) 23/21 becomes 23× 4/21×4 = 92/84

1/4 becomes 1×21/4×21 = 21/84

now subtract them

92/84 - 21/84 = 71/84

71/84 cannot be properly divided so, 71/84 is the answer.

He has 71/84 pounds of cherries with him.
