Answer:
- D. The water will be about 50°C. (54.8 (rounded up) is 50.)
- C. 23; the amount the temperature increases each minute.
Step-by-step explanation:
x = 6 (6 minutes)
5.3 x 6 + 23 = 54.8
5.3 x 6 = 31.8
31.8 + 23 = 54.48
2. C. 23: the amount of the temperature increased each minute.

Answer:
$
Step-by-step explanation:
Forget about the negative sign. First you have to find a least common denominator. This would be 63. Since we had to multiply 9 by 7 to get 63 we have to multiply the numerator (4) by 7. This gives us a new fraction of 36/63. Since we ha e to multiply 21 by 3 to get 63 we have to multiply 19 by 3. This gives us 57. So now we have 36/63 and 57/63. Then we add the negative sign back in making 57/63 -57/63. Now we add them together. Because one has a negative sign and one is positive the number has to be closer to zero. So the answer is -21/63.
Answer: 
Step-by-step explanation:
In order to round to the nearest thousandth, you must observe the digit to the right of the digit in the thousandth place and then:
- If it is less than 5, you must round down.
- If it is greater than or equal than 5, you must round up.
In this case, given the number:

You can notice that the digit to the right of the digit in the thousandth place is 9.
Since
, you must round up. Then:

Finally, to express this as a single-digit times a power of ten, move the decimal point three places to the right. Then you get:
