Answer: 0.249
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
We can think of 24.9% as the ratio 24.9 to 100 or 24.9 ÷ 100.
Remember that dividing by 100 moves the decimal point two places to the left so 24.9 ÷ 100 will move the decimal point two places to the left which would give us .249 or 0.249.
Therefore, 24.9% can be written as the decimal 0.249.
Answer: Uhh
Step-by-step explanation:
Answer:
1) -15/32
2) 2/15
3) -203.5
4) -3/2 = -1.5
5) 10/3 = 3 1/3
Step-by-step explanation:
For 1, you just multiply the numerators and denominators together (3 by 5, 4 by 8) and then because it is negative, add the negative sign.
For 2, you multiply again, but because there are 2 negative signs, it becomes positive.
For 3, you divide 81.4 by 0.4, you could also divide 814 by 4.
For 4, you keep change flip, so the equation would become -9/4 (-2 1/4=-9/4) and 3/2 would become 2/3. The equation would be (-9/4 * 2/3). Then, you would get -18/12 which is -3/2.
For 5, you just multiply 4/3 by 5/2 which is 20/6 and because 2 negatives, it becomes positive.
Write the equation of the line passing through the points (-7,5) and (-5,9):

.
You also have another two points (-3,13) and (-1,17). Look whether coordinates of these points satisfy the line equation:
1. For (-3,13) you have

;
2. For (-1,17) you have

.
Conclusion: All four points lie on the line y-5=2(x+7), so <span>the relationship shown by the data is linear.</span>
Answer: Correct choice is D.<span />
12c=22
6c=11
c=1 5/6
20c=33
c= 1 13/20
5/6 is about .83
13/20 is .65
12 chocolate bars for $22 is about $1.83 each
20 chocolate bars for $33 is $1.65 each
The 20 chocolate bars for $33 dollars has a better unit rate and is a better buy.
