You have to convert the lengths 3 feet in a yard and 12 inches in a foot.
10×3=30 feet
168÷12=14 feet
Then subtract, so 30-14=16
Answer:
240g in the ratio of 5:3:4
So we need to divide it evenly.
First add up all the ratios.
5+3+4= 12
Now divide 240 by the sum.
240/ 12 = 20
Now you multiply that into each ratio.
5*20 = 100
3*20 = 60
4*20 = 80
Now put it back in the ratio with the new numbers int he exact order as before.
Final Answer: 100 : 60 : 80
Check:
You can check by adding them all up to see if they all go into 240 OR you can divide them each by the number originaly given and you should get 20.
100 + 60 + 80 = 240
100 / 5 = 20
60/3 = 20
80/4 = 20
Answer:
7 1/2 hours I believe is the correct answer. Hope it works!
To expand the given expression we proceed as follows:
(6x²-2x-6)(8x²+7x+8)
=6x²(8x²+7x+8)-2x(8x²+7x+8)-6(8x²+7x+8)
=48x⁴+42x³+48x²-16x³-14x²-16x-48x²-42x-48
putting like terms together:
48x⁴+(42x³-16x³)+(48x²-48x²)+(-16x-42x)-48
=48x⁴+26x³+0x²-58x-48
hence the answer is:
48x⁴+26x³-58x-48
B, the inverse is not a function, because to the x-value 0 the inverse relation orders two values: the 1 and the 5 as well.
