The formula F=1.8C+32 can be used to convert temperature units. F is degrees Fahrenheit, and C is degrees Celsius.
Answer:
-40 °F = -40 °C
Step-by-step explanation:
The formula F = 1.8C + 32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius. Complete the equation you can solve to find that temperature and then use it to find the temperature. Use the variable C to represent the number of degrees Celsius where degrees Fahrenheit and degrees Celsius are the same. The equation is . The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is °C.
F = 1.8 C + 32 (1)
There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius
Then,
F = C (2)
Substitute (2) into (1)
F = 1.8 C + 32 (1)
C = 1.8C + 32
Subtract 1.8C from each side
C – 1.8 C = 32
-0.8C = 32
Divide both sides by -0.8
C = 32 / -0.8
C = -40
Substitute C = -40 into (1)
F = 1.8C + 32 (1)
F = 1.8(-40) + 32
F = -72 + 32
F = -40
Therefore,
The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is -40
That is,
-40 °F = -40 °C

Answer:
-3 1/8
Step-by-step explanation:
This can be done by setting up the following equation. (I'm going to convert 1/4 to .25 to make things easier)
-1.25/1 = x/2.5
x = -3.125 or -3 1/8
Mark is six years older than his brother Sam. The sum of their ages is 30. Let 'a' be Sam's age.
Answer:
a = 12 years
Step-by-step explanation:
Mark is 6 years older than his brother Sam. Now, we are asked to represent Sam’s age by a. This means that if Sam is a years old, Mark is (a + 6) years old.
The sum of their ages is 30, this means that when we add their ages together, we get the sum of thirty.
Mathematically this means a + a + 6 = 30
2a + 6 = 30
This is the equation needed to get a. To get a , we proceed to solve the equation to completion.
2a = 30 - 6
2a = 24
a = 24/2
a = 12
What are the answers? I’m very confused! Emergency!!
The roots are x = 4 and 2
I'm really sorry if this is wrong but basically 3x4 = 12 and 12x which they both could be mutiplied by 2 to get 24

The radioactive substance polonium-210, with a half-life of 138.39 days, is present in tobacco. Suppose that the soot in an ex-smoker's lungs contains 100 milligrams of polonium-210. How much radioactive polonium will remain after one year of not smoking
Answer:
16.07 milligrams
Step-by-step explanation:
From the question,
Using the formula of radioactive decay,
R/R' = 2ᵃ/ᵇ..................... Equation 1
Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.
Make R' the subject of the equation
R' = R/(2ᵃ/ᵇ)................ Equation 2
Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days
Substitute these values into equation 2
R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)
R' = 100/(6.222)
R' = 16.07 milligrams of plonium-210

Step-by-step explanation:
The scale of scores for an IQ test are approximately normal with mean 100 and standard deviation 15. The organization MENSA, which calls itself the “high IQ society”, requires a score of 130 or higher. What percent of adults are between IQ of 100 and 130 ?
A)68%
B)47.5%
C)95%
D)81.5%
Answer:
B) 47.5%
Step-by-step explanation:
Refer to the normal distribution chart attached. If 130 is 2 standard deviations higher than the mean (ignore the numbers beneath the percentages), then by the empirical rule, this means that 34%+13.5%=47.5% of adults are between IQs of 100 and 130. Therefore, option B is correct.

The prom committee is buying Brownies and Cookies. Brownies cost $2 each and Cookies cost $1.50. They need 45 treats and have $82.50 to spend. How many of each should they buy? You need Variables, Equation, and have to explain the solution
Answer:
Number of brownies = 30
Number of cookies = 15
Step-by-step explanation:
Given:
Cost of each brownie = $2
Cost of each cookie = $1.5
Total number of treats = 45
Total amount = $82.50
Find:
Number of cookies and brownie
Computation:
Assume;
Number of brownies = b
Number of cookies = c
So,
b + c = 45........eq1
2b + 1.5c = 82.50...........eq2
Eq1 x 2
2b + 2c = 90 ..................eq3
Eq 3 - Eq 1
0.5c = 7.5
c = 7.5 / 0.5
Number of cookies = 15
Number of brownies = 45 - Number of cookies
Number of brownies = 45 - 15
Number of brownies = 30

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

How many times as great as 6 x 10^4 is 3 x 10^7? Enter the answer in the box.
Answer:
5 * 10^2 times greater
Step-by-step explanation:
Here , we want to know how many times bigger is a certain number relative to another
What we have to do here is to make a division
We will have to divide (3 * 10^7) by (6 * 10^4)
That is;
(3 * 10^7) / (6 * 10^4) = 0.5 * 10^7/10^4
= 0.5 * 10^3 = 5 * 10^2
