The formula F = 1.8C + 32 allows you to find the Fahrenheit (F) temperature for a given Celsius (C) temperature. Solve the equat
Slav-nsk [51]

Answer:

The formula to calculate the Celsius temperature for a given Fahrenheit temperature is:

C=\frac{F-32}{1.8}

Step-by-step explanation:

Given formula:

F=1.8C+32

where F represents temperature in Fahrenheit and C represents  temperature in Celsius.

To solve the equation for C.

Solution:

We have,

F=1.8C+32

Subtracting both sides by 32.

F-32=1.8C+32-32

F-32=1.8C

Dividing both side by 1.8

\frac{F-32}{1.8}=\frac{1.8C}{1.8}

\frac{F-32}{1.8}=C

∴ C=\frac{F-32}{1.8}

Using the above formula, we can calculate the Celsius temperature for a given Fahrenheit temperature.

Students are painting a mural. So far the mural is painted 1/4 blue 2/8 red and 3/12 green. Use fraction strips to determine how
nirvana33 [79]
If you make the denominators all the same, the fractions are 3/12 , 3/12 , and 3/12. Then by simply adding them together you get that the mural is 9/12 painted. that then simplifies to  3/4 or 75%

Hope this helps :)

Armando read 20 pages of his 200-page book in 4 hours. At this rate, how long will it take him to read the entire book? (5 point
denis-greek [22]
The answer is B:40 hours. You take 200 divided by 20 to get 10 (the amount of 20 page sections he needs to read) and then multiply 10 by 4 (the speed he reads).

On a six-question multiple-choice test there are five possible answers for each question, of which one is correct and four are i
gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

given that on a six-question multiple-choice test there are five possible answers for each question, of which one is correct and four are incorrect

By mere guessing probability for choosing correct answer = p = 0.2

also each question is independent of the other

Hence if X is the number of correct questions then

X is binomial with p = 0.2 and n = 6

a) being correct on three questions,

=P(X=3) = 0.08192

(b) being correct on four questions,

= P(X=4) = 0.01536

(c) being correct on all six questions

=P(x=6) = 0.000064

Find the absolute value vertex. In this case, the vertex for y=|x−5|y=|x-5| is (5,0)(5,0).

(5,0)(5,0)

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

(−∞,∞)(-∞,∞)

{x|x∈R}{x|x∈ℝ}

For each xx value, there is one yy value. Select few xx values from the domain. It would be more useful to select the values so that they are around the xx value of the absolute valuevertex.
