Answer:
=−m3n9+a3
Step-by-step explanation:
Let's simplify step-by-step.
a3−m3n9
=a3+−m3n9
Let the number = X
You have X^8 / X^5
When dividing two numbers with powers, Simplify the expression by subtracting the powers.
8-5=3
so X^8 / X^5 becomes x^3
Now you have x^3 = 64
To find x take the cubic root of 64:
X = ∛64
X = 4
The number is 4
Let the angle = x
Using the figure below, to find x, setup the equation:
x+70+x=180
2x+70=180
2x=110
x=55°
So the ball hits the surface at 55° and bounces back at 55°.
Answer: 55°
Answer:
D.) This system has infinitely many solutions
Step-by-step explanation:
y = -4x - 6
-4x - y - 6 = 0
-4x - y - 6 = 0
-y = 4x + 6
-y/-1 = 4x/-1 + 6/-1
y = -4x - 6
There are infinitely many solutions, because both of the lines are exactly the same. As show below ! Hope this helps once again ^w^
16.3%=0.163
353(0.163)=57.539
57.539 is rounded to 57.5
There are 57.5 millimeters of acid. Hope this helps!
