5. You have correctly shown the decimal equivalents of the numbers in selection C. Those are in order. The decimal equivalents for selection D would be
... -1.33, -2.00, -1.00, -0.08, -0.07
The first of these is greater than the second of these, so this list is not in order. The correct choice is D.
6. √169 = 13, the only rational number in the lot. The correct choice is C.
8. All the numbers except the ones with radicals are rational numbers, so the appropriate choice is the one that lists the radicals only: G.
9. You have correctly plotted the points. When you connect them to make a geometric figure, you get a triangle that is 6 units high and 6 units wide. Its area will be half that of a square that is 6×6, so is 18 square units.
_____
The formula for the area of a triangle is
... A = (1/2)bh
where b is the base length of the triangle (6 units), and h is the height (6 units). Filling in the numbers you have, this is
... A = (1/2)·6·6 = 18 . . . . square units.
When you have a plot like this on a graph, it is usually pretty easy to see that the triangle area is half the area of a rectangle (or square) with the same height and width.
so.. whatever "x" is, we know 1125 + x = y
and whatever the alcohol concentration yield may be, we know
(1125)(0.9) = 0.75y
(1125)(0.9) = 0.75y <--- solve for "y", that's how much the final amount of milliliters will be
how much pure water was added? subtract 1125 from that, or y - 1125
Answer:
Step-by-step explanation:
Your answer
Assume that
Sammie is x,,,, Jennie is 9 years younger than him. So, Jennie ( y) = x-9
According to second condition eq is
(X-5) = 4(y-5)
Place the value of y in eq 2
You will find x= 17
Put x in eq 1
Y = 8
Answer:
y = 4
Step-by-step explanation:
-1y = -4
Divide both sides by -1 to get y by itself.
-1/-1 = -4/-1
y = 4
It's positive because there are two negatives, which mean they cancel out.
Odd function must pass through origin so first two options are not correct.
Odd function must be rotational symmetry around origin. So last option is not correct.
So answer is C.
