Do you mean ounce or once
Answer:
Step-by-step explanation:
A is correct.
2/3 > 4/8
5/9 > 7/12 This one is close. They are both nearly 1/2, but 9<12 and when you divide something by 9 the remainder is going to be larger than if you divide by 12.
The second one is incorrect.
3/4 > 5/9 5/9 is close to 1/2. Three quarters is much greater than 1/2
3/10 is much smaller than 5/9
The third one is correct. 1/10 and 5/6 are much larger than the two fractions on the right. The right side = 56/60 which is very nearly one. The left side is nowhere near that large. (I did estimate the right side).
The fourth one is correct. 9/10 is much larger than 2/3 and 5/9 is larger than 5/12. 5/9 is over 1/2 and 5/12 is under one half. So the arrow in the fourth one is going the right way.
Step-by-step explanation:
To find the area of a right triangle, you multiply the two legs of the triangle and then divide that result by 2. The reason this works is because a right triangle's area is <em>exactly half</em> the area of a rectangle using the same legs.
(f*g)(x) = (x-4)(2x+1) = 2x² + x - 8x - 4 = 2x² - 7x - 4
(f-g)(x) = x-4 - (2x+1) = (x-4)-2x-1 = -x - 5
(f+g)(3) = 3 - 4 + 2*3 + 1 = -1 + 6 + 1 = 6
7-5v = -v-1 -6v
7-5v= -7v-1
-5v+7v= -1-7
2v = -8
v = -8/2
v = -4
