Answer:
is the name of your account from little mermaid? :DDD
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
now just refer to the above ( also copy and paste the above on your computer some where so you have it always)
sin( D )= 28 / 53
sin( E ) = 45 / 53
cos(D) = 45 / 53
cos(E) = 28 / 53
7x^2 - 32x - 60
Factor by grouping,
(x - 6) (7x + 10)
width = x
length = 3 + x
perimeter = x + x + ( 3 + x ) + (3+x)
18 = x + x + ( 3 + x ) + (3+x)
x + x + ( 3 + x ) + (3+x) = 18
6 + 4x = 18
4x = 12
x = 3
Answer:
6%
Step-by-step explanation:
3/50 x 100/1% = 3/2 x4/1% = 12/2%=6%
10 weeks is the number of weeks they have been saving their money.
Duane = $5 every two weeks
Mick = $2 every week.
Get the value of Duane's weekly contribution = $5 / 2 = $2.5
Duane's share + Mick's share = $45
$2.5x + $2.0x = $45 ===>> equation can also be x(2.5 + 2) = 45
$4.5x = $45
$4.5x / $4.5 = $45 / $4.5
x = 10 weeks.
To check:
$2.5(10) + $2(10) = $45
$25 + $20 = $45
