Answer:
13.3%
Step-by-step explanation:
102 min - 90 min = 12 min
So she was off by 12 minutes. As a fraction of her original guess, that is 12/90.
As a percentage, this is 13.3333...
Rounded to the nearest 10th of a percent (to 1 decimal place, 0.1) this is 13.3

____ ÷ 100 = _____
B. What is the length, in feet, that the planks are allowed to vary? Remember, the · indicates multiplication.
____ · ____ = ____ foot
C. What is the length of the shortest allowable plank and the longest allowable plank cut by the machine?
Shortest: 8 - ___ = ___ feet
Longest: 8 + ___ = ___ feet
Answers
Answer:
A.
To express 1/2% as a decimal, you divide 1/2 by 100. You can use a fraction bar or a slash to indicate division. Like this:
1/2 ÷ 100 = 0.005
or
1/2 / 100 = 0.005
B.
To find the length that the planks are allowed to vary, you multiply the decimal value of 1/2% by the intended length of 8 feet. Like this:
0.005 · 8 = 0.04 foot
C.
To find the shortest and longest allowable planks, you subtract and add the variation length from and to the intended length of 8 feet. Like this:
Shortest: 8 - 0.04 = 7.96 feet
Longest: 8 + 0.04 = 8.04 feet
Show your work and write an expression using the following criteria:
A dividend is greater than 1,000
The quotient is 52 with a remainder of 18
please help me, fast!
Answers
Dividend (D) > 1,000
Quotient = 52
Remainder = 18
Based on these criteria, we can set up the equation as follows:
D = Quotient × Divisor + Remainder
Since the quotient is 52 and the remainder is 18, the equation becomes:
D = 52 × Divisor + 18
To meet the criteria that the dividend is greater than 1,000, we need to find a suitable value for the divisor. We can do that by rearranging the equation:
D - 18 = 52 × Divisor
Now, let's choose a value for D that is greater than 1,000. For example, let's use D = 1,500:
1,500 - 18 = 52 × Divisor
1,482 = 52 × Divisor
Dividing both sides by 52:
Divisor = 1,482 / 52
Simplifying:
Divisor ≈ 28.5
Therefore, the expression that satisfies the given criteria is:
Dividend (D) = 1,500
Quotient = 52
Remainder = 18
Divisor ≈ 28.5
The equation becomes:
1,500 = 52 × 28.5 + 18
