The formula used to convert degrees Celsius to degrees Fahrenheit is
F=?C +32
Convert 68°F to degrees Celsius. Solve the formula for C, and then use it to
convert the temperature.
Which is the correct formula and conversion?
Answer:
9
Step-by-step explanation:
The correct conversion is 68°F = 20°C.
What is unit conversion?
Conversion is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We are given that;
To convert 68°F
Now,
To solve the formula for C, we need to isolate C on one side of the equation. We can do this by subtracting 32 from both sides and then dividing by 1.8. The steps are:
F = 1.8C + 32
F - 32 = 1.8C
(F - 32) / 1.8 = C
Therefore, the correct formula for C is:
C = (F - 32) / 1.8
To convert 68°F to degrees Celsius, we can plug in F = 68 into the formula and simplify. The steps are:
C = (68 - 32) / 1.8
C = 36 / 1.8
C = 20
Therefore, after conversion the answer will be 68°F = 20°C.

Josh received his allowance on Tuesday. He spends 3/8 of his allowance on Tuesday night and 2/3 of the remainder on Wednesday morning. What part of his allowance is left for the rest of the week?
Josh starts with 8/8 (or any other fraction that equals 1) of his allowance. He then spends 3/8 of it.
8/8 x 3/8 = 3/8
8/8 - 3/8 = 5/8
He spend 3/8 of his allowance, leaving him with 5/8 left. Then Josh spent 2/3 of that remaining amount.
5/8 x 2/3 = 10/24 = 5/12
Josh has 5/12 of his allowance left for the rest of the week.
Hope this helps!

What is Simple interest?Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
Steps taken by the student to solve the formula of the simple interest for the values of '',
Step 1 : A = P( 1 +rt)
Step 2 : A = P + rt
Step 3 : A - p = rt
Step 4 : r = (A - P)/ t
There is an error in step 2 where distributive property was not followed.
Correct steps should be,
Step 1 : A = P( 1 +rt)
Step 2 : A = P + Prt [By distributive property]
Step 3 : A - P = Prt
Step 4 : r = (A-P)/Pt
Therefore, error was made in step 2.

Mr Hamal had Rs 4,400.He purchased 6 kg of rice at Rs 75 per kg,2packets of oil at Rs 125 per packet and he gave Rs3,300 to his wife. he divided the remaining sum between his son and daughter equally , find the share of each them
Answer: Therefore, his son and daughter got Rs 200.
Step-by-step explanation:
6 kg of rice = 75*6 = Rs 450
2 packets of oil = RS 2*125 = RS 250
now total money he spent = Rs 450 + Rs 250 + Rs Rs 3,300
= Rs 700 + Rs 3,300
= Rs 4000
Money left = Rs 4,400-Rs 4000 = Rs 400
so
400/2 = Rs 200

A chemical company makes two brands of antifreeze. The first brand is 55% pure antifreeze, and the second brand is 80% pure antifreeze. In order to obtain 180 gallons of a mixture that contains 65% pure antifreeze, how many gallons of each brand of antifreeze must be used?
Step-by-step explanation:
the first brand = (65-55)/(80-55) x 180
= 10/25 × 180
= 72 gallons
the second brand = (80-65)/(80-55)×180
= 15/25 × 180
= 108 gallons
