Answer:
5100 cm of wax will make 17 candles
Step-by-step explanation:
Each candle is 5 cm long, 4 cm wide, and 15 cm tall
to know the space they cover, we divide it with their volume and since they are in rectangular prism
Volume is length x width x height
5 x 4 x 15 = 20 x 15 = 300cm
1 candle = 300cm
what number of candle is represented as x
1 candle comprises of 300cm wax
x = 5100
300x = 5100 x 1 =5100
300x= 5100
x= 5100/300 = 17
5100 cm of wax will make 17 candles
Answer:
B
Step-by-step explanation:
You can rule out all others. A is wrong because a triangle cannot be acute and obtuse at the same time. C is wrong because a polygon dosen't neccassarily need to be a triangle, for example, a polygon is a closed shape, so it could be a rectangle. It isn't D because there are obtuse triangles out there. So, the only one left is B.
Answer:
i think its 24
Step-by-step explanation:
2=2
You multiply it with the same number you use for the denominator.
in this case 3/4 and 7/10
you find the LCM of the denominator is 20
so for 4 to become 20 you multiply by 5 then for the numerator 3 also multiply by 5, so you get 15/20
its the same also with 7/10, you multiply both the numerator and the denominator by 2 and get 14/20
hope it help... :)
