Fed [463]

She eats 180 kg of popcorn every month.

Step-by-step explanation:

Since Ms. Louis' daughter eats 9 bags a month and every bag weighs 20 kg you will just need to multiply the number of bags (9) × the weight of the bags (20) to figure out how many kilograms she eats. In this case she eats 180 kilograms of popcorn a month.

Find the acute angle

Scrat [10]

Answer:

22°

Step-by-step explanation:

Since the triangle is right use the sine ratio

sinQ = $\frac{opposite}{hypotenuse}$ = $\frac{7}{19}$ , hence

Q = $sin^{-1}$ ( $\frac{7}{19}$ ) = 22° ( nearest degree )

there are two factors of -36 such thatone factor is 11 less than half of the other factor. choose all the pairs of these factors

aleksandrvk [35]

Let one factor be x. Second factor is 11 less than half of this factor, so second factor will be (0.5x - 11). The product of these two factors is -36.

So,

$-36=x(0.5x-11) \\ \\ 
-36=0.5 x^{2} -11x \\ \\ 
-72= x^{2} -22x \\ \\ 
 x^{2} -22x+72=0 \\ \\ x^{2} -18x-4x+72=0 \\ \\ 
x(x-18)-4(x-18)=0 \\ \\ 
(x-4)(x-18)=0 \\ \\ 
x=4, x=18$

If,
x = 4, the other factor will be = 0.5(4) - 11 = - 9
If,
x = 18, the other factor will be = 0.5(18) - 11 = -2

So, there are two possible set of factors.
1) 4 and -9
2) -2 and 18

From these -2 and 18 is available in the options. So this is the correct answer.

Which rule describes the composition of

ExtremeBDS [4]

Answer:

The second one: r x-axis. R 90(x,y)

Step-by-step explanation:

You can see that from ABC to A'B'C', it's rotated a positive 90 degrees. then, from A'B'C' to A"B"C", reflected across x-axis. and when writing the transformation, it goes by last to first. that's why the R 90 comes first.
