Answer:
28 cm
Step-by-step explanation:
volume of a rectangle: l*w*h
the first cuboid: 7*4*2= 56
56=2*1*y
56=2y
28=y
The problem statement tells us ...
16 cm = 2.5 cm + (1/4)*(large gear diameter)
We can subtract 2.5 cm and multiply by 4 to find the large gear diameter.
13.5 cm = (1/4)*(large gear diameter)
54 cm = (large gear diameter)
The diameter of the larger gear is 54 cm.
Answer:
<u>The actual weight is 1.1% less (100 - 98.9) than the labeled weight.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question properly:
Labeled weight of the bag of chocolates = 0.384 pounds
Actual weight of the bag of chocolates = 0.3798 pounds
2. How much have you or lighter are the chocolates and the stated on the label. Show your reasoning.
Let's find how much we have comparing the labeled weight and the actual weight, using a Direct Rule of Three, this way:
Weight Percentage
0.384 100 %
0.3798 x %
0.384x = 0.3798 * 100
0.384x = 37.98
x = 37.98/0.384
x = 98.9 (Rounding to one decimal place)
<u>The actual weight is 1.1% less (100 - 98.9) than the labeled weight.</u>
The cost is $395. You are trying to find <em>n</em> in 24<em>n</em> + 35.
Set C = 395.
You get 395 = 24<em>n</em> + 35.
Solve for <em>n</em> by first subtracting 35 from both sides of the equation:
395 - 35 = 360.
24<em>n</em> + 35 - 35 = 24<em>n</em>.
Now you have 360 = 24<em>n</em>. Divide both sides by 24 to get:
15 = <em>n</em>.
So, 15 birthday cakes are made when the cost is $395.
