Answer:
Step-by-step explanation:
volume of cylinder = πr²h
πr²h = 127.23 cubic inches
3.14 * 3 * 3 * h = 127.23
h = 127.23 / 3*3*3.14
=127.23 * 100 /3*3*3.14*100
=12723/ 3*3*314
= 4241 / 3*314
=4241/ 942
=4.502 inches
h = 4.5 inches
Let the length of equal sides be x cm. Perimeter = x cm + x cm + Base = 4 2/15 cm 2x + 4/3 = 62/15 On transposing 4/3 to R.H.S, we obtain 2x = 62/15 - 4/3 2x = 62 - 4 x 5/15 = 62 - 20/15 2x = 42/15 On dividing both sides by 2, we obtain 2x/2 = 42/15 x1/2 x = 7/5 = 1 2/5 Therefore, the length of equal sides is 1 2/5 c m.
Answer:
Yes
Step-by-step explanation:
If you subtract the p4 and p2 you get p2. q5-q2 is q3. 39/3 is 13. Therefore those expressions are equivalent.
Answer:
Due to the distributive property the expression are the same.
Step-by-step explanation:
Sadie expression is "perimeter = 2*(length + width)", while Eric's is "perimeter = 2*length + 2*width". The value for both is always the same for any rectangle, because the expressions are the same due to the distributive property. To prove this we will expand Sadie's expression as shown below:
perimeter = 2*(length + width)
perimeter = 2*length + 2*width
Which is the same as Eric's.
Answer: X = -1 and Y = 3
—————————————
X + Y = 2
X = 2 - Y
————————
Y = x + 4
Y = 2 - Y + 4
2Y = 2 + 4
2Y = 6
Y = 3
————————
X + Y = 2
X + 3 = 2
X = -1
