Answer:
2.5 × 10⁻⁹ × 1.5 × 10³ = 3.75 × 10⁻⁶
As you can see, you multiply the numbers in front of 10s, and add the exponents.
i think
X=4 is the awnser too this one
X = apples trees
Y= azaleas
6x + 5y = 219
3x + 4y = 132
-2(3x + 4y = 132)
-6x - 8y = -264
6x + 5y = 219
-3y = -45
-3y/-3 = -45/-3
y = 15
6x + 5y = 219
6x + 5(15) = 219
6x + 75 - 75 = 219 - 75
6x/6 = 144/6
X = 24
The cost for each apple tree is $24 and fit each azalea is $15
Check the picture below.
since the triangle is a 30-60-90 triangle, we can use the 30-60-90 rule.
now, we know half-side is "b", which is 7, meaning the length of a side in that hexagon is 7+7 or 14.
Since there are 6 sides the "perimeter", namely the sum of its sides is 14*6, or 84. The length from the center of the regular polygon to a side is the "apothem".
Never fear, help is here.... Pic below
Maybe don't add drawings, or do....?
