Convert 180C into Farenheit
- A.
356 F
- B.
32 F
- C.
0.00375 F
- D.
374 F
Correct Answer
A. 356 FExplanation
To convert Celsius to Fahrenheit, you can use the formula: F = (C * 9/5) + 32. In this case, to convert 180C to Fahrenheit, we can substitute C with 180 in the formula. By solving the equation, we get F = (180 * 9/5) + 32 = 356 F. Therefore, the correct answer is 356 F.Rate this question:

The recipe asks for the cake to bake at 350F. The oven's guage is in centigrade. Which option is closest?
- A.
145 C
- B.
160 C
- C.
175 C
- D.
190 C
Correct Answer
C. 175 CExplanation
The correct answer is 175 C. To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and then multiply by 5/9. So, to convert 350F to Celsius, we subtract 32 from 350, which gives us 318. Then, we multiply 318 by 5/9, which equals approximately 176.67. Since we are looking for the closest option, 175 C is the closest to the converted temperature of 176.67 C.Rate this question:

The temperature today ranged from -10C in the morning to +15C in the afternoon. What was the change in temperature?
- A.
-25 C
- B.
+25 C
- C.
-15 C
- D.
+15 C
Correct Answer
B. +25 CExplanation
The change in temperature is +25C because the temperature increased from -10C in the morning to +15C in the afternoon. To find the change, we subtract the initial temperature from the final temperature, which gives us +15C - (-10C) = +25C.Rate this question:

Exchange 25 ounces into pounds and ounces.
- A.
2 lb, 56 oz
- B.
1 lb, 5 oz
- C.
2 lb, 1 oz
- D.
1 lb, 9 oz
Correct Answer
D. 1 lb, 9 ozExplanation
To convert ounces into pounds and ounces, we divide the given number of ounces by 16 (since there are 16 ounces in a pound) to get the number of pounds. The remainder gives us the number of remaining ounces. In this case, 25 ounces divided by 16 gives us 1 pound with a remainder of 9 ounces. Therefore, the correct answer is 1 lb, 9 oz.Rate this question:

We are shipping a parcel to England. The rate is $3.99 per oz. This box weighs 360g. What is the cost?
- A.
$50.67
- B.
$1.44
- C.
$3.18
- D.
$51.88
Correct Answer
A. $50.67Explanation
The cost of shipping the parcel to England can be calculated by converting the weight of the box from grams to ounces and then multiplying it by the rate per ounce. Since 1 ounce is approximately equal to 28.35 grams, the weight of the box in ounces is 360g / 28.35g/oz = 12.69 oz. Therefore, the cost of shipping the parcel is 12.69 oz * $3.99/oz = $50.67.Rate this question:

Five pounds of apples cost $7.99. What is the cost of eight pounds?
- A.
4.99
- B.
$12.80
- C.
$12.78
- D.
$13.95
Correct Answer
C. $12.78Explanation
The cost of the apples is directly proportional to the weight. Therefore, if 5 pounds of apples cost $7.99, then the cost of 8 pounds can be calculated by finding the unit price and multiplying it by the weight. The unit price is $7.99 divided by 5 pounds, which is $1.598 per pound. Multiplying this unit price by 8 pounds gives a total cost of $12.78.Rate this question:
