204 times .46 equals 93.84, to round of it would be 93.8
Answer : 2 2/15
To begin you need to convert the fractions into something they both can go into. Sometimes it is easier to multiple the two denominator of the fractions, which in this case it is.
So, 3 times 5 is 15
This means your going to convert your fraction into 15th
1/3 is 5/15
This is because you need to times the bottom by 5 in order to get 15, so you need to do the same with the top.
1/5 is 3/15
This is because you need to times the bottom by 3 to get 15 so you do the same with the top
Next you just subtract the amounts separately
4-2 = 2
5/15 - 3/15 = 2/15
This means your answer is 2 2/15
Answer:a. 17,570 b. 48.14
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let base be b, height be h
h = 7+b or we can say that b = h -7
A = 15 cm²
General formula for area of a triangle
A = b · h
Substitute what we know to find the height h
15 = (h-7) · h
15 = h² -7h
0 = h²-7h -15
h = (7 ±√49 + 4·1·15)/2
h = (7 ±√109)/2
h ≈ -1.72 reject this solution because height cannot be negative
h ≈ 8.72 cm
