Answer:
The last option 15,000 grams is correct.
Step-by-step explanation:
How many grams are in 15 kilograms?
We must know the relation between kilograms and grams.
1 kg = 1000 grams.
Now we have been asked to calculate the grams in 15 kilograms.
So, 15 kilograms has = grams
Therefore, the last option 15,000 grams is correct.
Answer: 0.44mm
Step-by-step explanation:
In this problem we are asked for the height of a single playing chip. We know the volume of a cylinder is 25120 mm^3.
V=πr²h
25120=πr²h
The problem also gives the diameter of the case: 40mm.
To find radius, you divide the diameter in half.
d=2r
40=2r
r=20
With the radius, we can add that to the volume equation.
25120=(20)^2h
25120=400πh
All we have left is to find the height.
h=25120/(400π)
h≈20mm
Now that we know the height, we can find the height of a single chip. The problem states about 50 chips can fit in a case. To find the height of a single chip, you would divide 20 by 50.
20mm/50 chips=0.4mm/chip.
Answer:
Total cost of the article altogether is $42.75 .
Step-by-step explanation:
As given
An article retails for $37.50.
The city sales tax is 6%, and the federal excise tax is 8%.
6% is written in the decimal form
= 0.06
Price of city sales tax = 0.06 × Article cost
= 0.06 × 37.50
= $ 2.25
8% is written in the decimal form
= 0.08
Price of federal excise tax = 0.08 × Article cost
= 0.08 × 37.50
= $ 3
Thus
Total cost of the article altogether = Article cost + Price of city sales tax + Price of federal excise tax
Putting all the values in the above
= $ 37.50 + $2.25 + $3
= $ 42.75
Therefore the total cost of the article altogether is $42.75 .
1- y(y + 5) = 750
2- y^2 – 5y = 750
3- 750 – y(y – 5) = 0
4- y(y – 5) + 750 = 0
5- (y + 25)(y – 30) = 0
Answer:
this problem is Non-proportional
