Answer:
3 cubic inches
Step-by-step explanation:
Volume of cone shown= 6 cubic inches
Let the base diameter be 2x.
Therefore, radius= x
Since the base diameter is the same, the base area is the same.
Using the formula, volume of cone
Subst. the known value of into the equation.
Thus, volume of cone= 1(3)= 3 cubic inches
The correct solution is x=5,y=1
Ste<u>p-by-step explanation:</u>
Given the set of equations
4x-9y=11(1)
10x-9y=41(2)
we have to determine the values of x and y
solve this using elimination method
4x-9y=11(1)
10x-9y=41(2)
(2)-(1)
10x-4x-9y-(-9y)=41-11
10x-4x-0=30
6x=30
x=30/6
=5
substitute y in (1)
x=5
y=1
So start with your standard numbers. Divide 1.6 by 4 and you get 0.4
With the exponents, since you’re dividing, you keep the base and subtract the exponents. So 3-6=-3
You’d get 0.4 x 10 to the -3 but that’s not correct scientific notation because you have to have a value 1 or larger.
Move the decimal to the right one place (making the standard number larger) and make the exponent smaller to balance it out.
4 x 10 to the -4 power.
Answer:
320
Step-by-step explanation:
Since 112 pages is 35% of a book, we can set x to the total number of pages.
112=(0.35)(x)
We get x=320
