Answer: No, she does not have enough.
Step-by-step explanation:
1. You have the following information given in the problem above:
- The measures of the three pieces are: 32 centimeters, 41.19 centimeters and 57.8 centimeters long.
- She need 200 centimeters of ribbon for the box.
2. Therefore, you must add the measures given in the problem to know if Marie has enough ribbon to decorate the gift box. Then:
3. As you can see:
130.99 cm<200 cm
Therefore, she does not have enough ribbon.
Answer: D
Step-by-step explanation:
The formula for volume of a rectangular prism is V=LHW.
4/5×3/5×2/5=24/125
The correct answer is d. 8.6602
Each number in the sum is even, so we can remove a factor of 2.
2 + 4 + 6 + 8 + ... + 78 + 80 = 2 (1 + 2 + 3 + 4 + ... + 39 + 40)
Use whatever technique you used in (a) and (b) to compute the sum
1 + 2 + 3 + 4 + ... + 39 + 40
With Gauss's method, for instance, we have
S = 1 + 2 + 3 + ... + 38 + 39 + 40
S = 40 + 39 + 38 + ... + 3 + 2 + 1
2S = (1 + 40) + (2 + 39) + ... + (39 + 2) + (40 + 1) = 40×41
S = 20×21 = 420
Then the sum you want is 2×420 = 840.
20% of 90 pizzas is 22.5 pizzas
And since you can’t just buy half a pizza it would have to be 23 pizzas :)
