Answer:

Correct answer is 8.9

Step-by-step explanation:

When you use the Pythagorean theorem formula a^2 + b^2 = c^2, we can easily calculate the missing side by plugging in the given numbers. So when you do the math, 2.8^2 + 8.5^2 it will give you 80.09, then when you square root it, it will be 8.9. And that is your answer

A nurse mixes 50 cc of a 60% saline solution with a 20% saline solution to produce a 28% saline solution. How much of the 20% so

Alex17521 [72]

Answer:

200 cc

Step-by-step explanation:

Let x be the added 20% solution.

<u>The salt content is same:</u>

50*0.6 + x*0.2 = 0.28*(x + 50)
30 + 0.2x = 0.28x + 14
0.28x - 0.2x = 30 - 14
0.08x = 16
x = 16/0.08
x = 200

Find sin angle∠ A. <br> A. 3/5<br> B. 4/5<br> C. 1<br> D. 5/4

Rzqust [24]

Answer:

The answer is B.

Step-by-step explanation:

Recall SohCahToa, where $sin(A)=opp/hyp$ .

The opposite side (to angle A) here is 8, while the hypotenuse is 10.

Thus, we have:

$sin(A)=8/10=4/5$

The correct answer is B.

Create triangle A’B’C by reflecting triangle ABC over the y-axis on the coordinate plane. What are the new coordinates of the ve

pickupchik [31]

Answer:

Step-by-step explanation:

When talking about reflection, we usually mean reflecting across a line, or axis. Reflecting a shape means looking at the mirror image on the other side of the axis. Consider the point (x,y), if you reflect this point across the y-axis you should multiply the x-coordinate by -1, so you get:

$(x,y)\rightarrow(-x,y)$

For triangle ABC we have:

$A(-4,2) \\ \\ B(-1,3) \\ \\ C(-1,-4)$

Therefore, the reflecting points are:

$A'(4,2) \\ \\ B(1,3) \\ \\ C(1,-4)$

Both the original triangle and the reflected one are shown below.
