Answer:
Step-by-step explanation:
- Plain wrapping paper - p
- Shiny wrapping paper - s
<u>Equations:</u>
- 10p + 4s = 170
- 5p + 3s = 105
<u>Double the second equation and subtract from the first one:</u>
- 10p + 4s - 10p - 6s = 170 - 210
- -2s = - 40
- s = 20
<u>Find p:</u>
- 10p + 4*20 = 170
- 10p = 90
- p = 9
Distance formula!!!!! yay i've done this umpth manytimes today for people so if you dont know distance formula is square root of (x1-x2)^2+ (y1+y2)^2.
0-(-7) -1-(-2)
7^2 + 1^2
49+1
sqr. root of 50
appx. 7.07 or the closest to it
For this you will use the tangent function. You have the adjacent side and have to find the opposite side.
tan x = opposite/adjacent
tan 25 = x/15
15 (tan 25) = x
6.9946 = x
So the boat is approximately 6.9946 m away from the lighthouse.
Answer:
Step-by-step explanation:
First, the problem asks for an expression; this means that there should be no equal sign. Also, the keyword "product" means that both the terms must be multiplied. So, is the final expression; this equals 96.
Answer:
116 degrees
Step-by-step explanation:
180 - (26 + 90)
180 - 116 = 64 degrees
180 - 64 degrees = 116 degrees
Angle 1 = 116 degrees
Hope that helps!
