Answer:
The largest number of pyramids she can make from 20 bars of chocolate is:
Step-by-step explanation:
Firstly, you must find the volume of the 20 bars of chocolate, remember that each bar contains 6 cubic inches of chocolate (6 in^3), so:
- Volume of the bars = 6 in^3 * 20
- <u>Volume of the bars = 120 in^3</u>
Now, you must find the volume of each pyramid, using the next formula:
- Volume of a pyramid = 1/3 B * h
Where:
<em>B = area of the square base.</em>
<em>h = height of the pyramid.</em>
How these values are given in the problem, we only replace the values in the formula:
- Area of a pyramid = 1/3 (1 in^2) * 2 in
- <u>Area of a pyramid = 2/3 in^3</u>
Finally, we divide the volume of the bars in the volume of each pyramid:
- Total number of pyramids = 120 in^3 / 2/3 in^3
- <u>Total number of pyramids = 180</u>
1/3 of 72 is 24 subtract 24 from 72 and get 48 and 1/4 of 48 is 12 so you subtract 12 from 48 and get 36 there for you have 36 dollars left over
Answer:
-3
Step-by-step explanation:
1. subtract 0.3 from both sides
2. add 3.7x to both sides
3. Divide both sides by -0.5
Answer:
the answer is c
Step-by-step explanation:
because it doesn't repeat the same number for example if it was two -1s it wouldn't be a function but positive and negative are different so yeah
1/2+1/2=1
2*12=24
d=24*25
d=600 miles
I believe I did it in my head so not entirely sure but I am heavily certain of my math
