Answer:
667.25 in³
Step-by-step explanation:
V = πr²h = 3.14 x 5² x 8.5 = 667.25
Answer:
Mikhail is 5 years old
Step-by-step explanation:
Represent each member with a variable.
X= Gabrille
Y=Mikhail
X+Y=20 (sum of their ages is 20)
X=3y (Gabrille is 3 times Mikhails age)
Substitute 3Y into the first equation (simultaneous equation)
. 3y+y=20
. 4y=20 (divide both sides by 4)
y=5
To check your answer.
X+5=20
X=20-5
X=15
15 is 5 times 3.
Answer:
P= 6h
Step-by-step explanation:
2(2h)+2h=p
(2*2h)+ 2h=p
4h+2h=p
6h
Alright, lets get started.
For making complete square, we will add and subtract 49 in this
Comparing the standard equation of parabola
where (h,k) are vertex
So, comparing the equation with standard one, h, k would be = (-7 , -89)
So, the vertex are (-7 , -89) : Answer
Hope it will help :)
For example,
45/100 In decimal would be 0.45
45/1000 in decimal would be 0.045.
I didn't really explain, but I gave an example. Hope this helped you?
