Answer:

4√3

Step-by-step explanation:

Use the acronym SOH CAH TOA and pick your angle. Im gonna pick the 30 degree angle. From the 30 degree angle, the x side is the hypotenuse, and the 2√3 is the opposite. I need to find H and O, which is the SOH part of my acronym.

Therefore Sin 30 = O/H. Then SIN 30 = 2√3/x.

We multiply both sides by x ⇒ x × sin 30 =2√3

Lastly we divide by sin 30. x = 2√3/ sin 30

We know that sin 30 is 1/2.

2√3 ÷ 1/2 (keep change flip) ⇒2√3 ×2 ⇒4√3

Sin 30 is equal to

You lost minus when you were adding two equations.
-176= - 22x -12y
<span>144 = 6x +12y
</span>-32= - 16x
x=2

88=11x+6y,
88=11*2+6y
6y=66
y=11

Check:
88=11x+6y=11*2+6*11=88 True
144=6x+12y=6*2+12*11=12+132=144 True

The cost of daylilies is $2.
The cost of pot of ivy is $11.

Answer:

n=601

Step-by-step explanation:

Formula used:

$n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}$

Solution:

$n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}$

Where,

$\frac{\alpha }{2}=0.025$

As there is no previous estimate for p

Then, p=0.5

Here on using the table

$z(\frac{\alpha }{2}) =1.959963985$

Also,

E=0.04

p=0.5

Thus,

n=600.2279407

On approximating the value,

n=601
