Answer:
C 9 *x^2 y^ 4 y^ 1/2
Step-by-step explanation:
(81x^4y^9)^1/2
We know that (ab)^1/2 = a^1/2 *b^1/2
(81) ^1/2 * (x^4) ^1/2 * (y^9)^1/2
We know that a^b^c = a^ (b*c)
(81) ^1/2 * (x^(4*1/2) * (y^(9*1/2)
9 *x^2 y^ 9/2
We know that y^9/2 = y^4 y^1/2
9 *x^2 y^ 4 y^ 1/2
The most simplest way to explain this is by breaking down the 60%.
Think about it.
If 60% space = 30 bikes
then 30% space = 15 bikes
then 10% space must be 5 bikes.
So we now know for sure 60% space = 30 bikes.
And 10% space = 5 bikes.
Then we know remaining 40% space = 20 bikes.
So total space = 100% space, for 50 bikes.
Answer:
4.3
Step-by-step explanation:
Because the y-coordinate stays the same, only look at the x-axis. Subtract 17.1 - 21.4 to get your length
The first picture would be choice answer c because the number of x's represent how many birds wings are this size. The number on the tic mark represents the size of the wing span. So you would take the number of x's times the tic mark represented under it. There are 3 birds with 3 1/8 wingspan so it wold be 3 1/8 *3. Hoped this helps for the first one!
