Hope this helps!, I have to have more than 20 characters so ignore this!
The whiteboards she bought cost $35, and she spent a total of $51.20, subtract to find out the total amount she spent on posters:
So she spent a total of $16.20 on posters, now divide by the amount one poster costs to find out how many posters she bought.
So she bought 3 posters.
Answer:
$80.00
Step-by-step explanation:
We have: 120 ft = 40 yards (divide the length value by 3
)
=> Jerome will cost: 40 x $2.00 = $80.00 for the fencing.
Answer:
[4, -1]
Step-by-step explanation:
Using the Elimination Method:
3x + y = 11
5x - y = 21
__________
8x = 32
__ ___
8 8
x = 4 [Plug this back into both equations to get the y-coordinate of -1]; -1 = y
The <em>y</em>'s are already <em>additive</em><em> </em><em>inverses</em><em> </em>[result in 0], canceling each other out.
I am joyous to assist you anytime.

Answer:
- sin(θ) = 4/5
- cos(θ) = 3/5
- tan(θ) = 4/3
Step-by-step explanation:
The mnemonic SOH CAH TOA was created to help you remember the relevant trig relationships. It is intended to remind you ...
Sin = Opposite/Hypotenuse
sin(θ) = 4/5
Cos = Adjacent/Hypotenuse
cos(θ) = 3/5
Tan = Opposite/Adjacent
tan(θ) = 4/3
__
In a right triangle, the opposite side (PQ) is the one that is not part of the angle (∠R = θ). The adjacent side (QR) is the shorter side that makes up the acute angle. The longest side (PR) is the hypotenuse.
