-33 < -7n - 12 < -26

1 answer:

3 0

-33 < -7n - 12 < -26
First step is to add 12 to both sides.
-33 < -7n < -26-21 < -7n < -14

Now divide both sides by -7.
3 < n < 2

Because you divided by a negative number though, you need to switch up the signs. Both the < will turn into >.
3 > n > 2

Right triangle similarity: Solve for x and y

OleMash [197]

Answer:

x=4 $\sqrt{5}$ ,y=8 $\sqrt{5}$

Step-by-step explanation:

sin∠SRT = sin∠TSV,

SO $\frac{x}{20} =\frac{4}{x}$ , $x^{2}$ =80,x= $\sqrt{80} =4\sqrt{5}$ ;

In the same way:

sin∠RSV = sin∠RTS,

SO $\frac{16}{y} =\frac{y}{20}$ ， $y^{2}$ =320,y=8 $\sqrt{5}$

Can someone help out? or explain?

Nataliya [291]

Y = 90 degrees

1) The angles on a straight line add to 180 degrees so 180-110= 70 degrees.

2) The angles in a triangle add to 180 degrees so 70+70= 140 degrees. The angle at the top of the triangle will have to be 40 degrees as 140+40= 180 degrees.

3) As x is half the angle at the top of the triangle (40 degrees), x will equal 20 degrees.

4) As the angles in a triangle add to 180 degrees 20+70=90 degrees 180-90=90 degrees.

5) Answer = 90 degrees

Given complex numbers u and v below,what is uv u=7i V=6-i

boyakko [2]

Answer:

7 + 42i.

Step-by-step explanation:

u v = 7i(6 - i)

= 42i - 7i^2 But i^2 = -1 so:

= 42i - 7(-1)

= 7 + 42i.
