Answer:
2/3
Step-by-step explanation:
Find the total amount of shirts: 6 + 8 + 4 = 18
Find the total amount of white and solid colored shirts : 8 + 4 = 12
Put the total amount of white and solid colored shirts over the total amount of shirts: 12/18
Simplify 12/18: 2/3
Answer:
y=(x-2)^2-81
Step-by-step explanation:
Again, nice problem. These are not super easy. You need to imagine the triangles in the figure and relate sides.
For instance: ADC, its hypotenuse is 15
For ABC, it is 20,
so 20/15 is the ratio between both triangles. Now let's choose the side with 'x'
x is one side of ADC, the corresponding side in ABC is 15 (the second longest sides). You need to rotate the triangles, etc ... That's the tricky part :)
So:
20/15 =15/x ----> x = 15*15/20 = 225/20 = 45/4
Which is C
Not sure whether it's too late to help you though!!!!
Also notice that it's kind of a product rule:
x * 20 = 15 * 15
I am sure the book explains a short way of getting to this equation, like sides opposite, blah blah, but what i told you is the reason. You asked for understanding it! Best luck!
Answer: 16.5 hours
Step-by-step explanation:
distance=rate*time
132=8*x
Divide by 8 on both sides
x=16.5
Answer:
25n^8
Step-by-step explanation:
Area of a square is length×length
Length=5n^4
Area=5n^4×5n^4
=(5×5)(n^4+4)
=(25)(n^8)
=25n^8
So the area of a square is 25n^8
