A cube and a rectangle prism both have 8 vertices
To answer this question, we have that the scale factor is 1 / 12, and it says that the model is 1/12 the size of the actual length.
Then, we have that the actual length is 21 feet. The size of the model is:
We need to remember that units are not mentioned in a scale factor.
Now, we need to transform the size of feet into inches. We know that in one foot we have 12 inches, then, we can take this into account to have the missing dimension item (length in inches):
Therefore, the missing dimension is 21 inches (the model is 21 inches in length.)
Answer:
1890, total cost of lights per week
Step-by-step explanation:
The lights cost 45 dollars per bulb and 6 go out per day, 45×6=270
270 is the cost to replace the bulbs of one day.
270×7=1890. 1890 is the cost for a whole weeks worth of replacing these bulbs.
Answer:
I am not sure which one it is due to what you put in. I think it would be A.
x = 0
y = 2/3
Step-by-step explanation:
Step: Solve x + 6y= 4 for x:
x + 6y + −6y = 4 + −6y
x= −6y + 4
Step: Substitute −6y + 4 for x in 2x + 3y = 2:
2x + 3y = 2
2 (−6y + 4) + 3y = 2
−9y + 8 = 2
−9y + 8 + −8 = 2 + −8
−9y = −6
-9y/-9 = -6/-9
y = 2/3
Step: Substitute 2/3 for y in x = −6y + 4:
x = −6y + 4
x = -6 (2/3) + 4
x = 0
Sorry if it is long and confusing. But I hope this helps!
