Answer:
( 1/2 0.5 mph )
Step-by-step explanation:
In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1.
X = 2.1 x tan(37)
x = 1.58 = 1.6
Answer: C
Step-by-step explanation:
Okay first set a comparison since the two triangles are similar
x-1/20=x-1+27/3x+8
x-1/20 = x+26/3x+8
cross multiply
20x+520=3x^2+8x-3x-8
3x^2-15x-528=0
3(x^2-5x-176)=0
im kinda lazy to factor this out so i used an online calculator right here but factor it out like a good kid
x=16, x=-11
it has to be positive so x=16
C
Answer:
-48.1818
Step-by-step explanation: then u round up to 3 singnificant figures
Use PEMDAS
1. 2(2^2)-2
=2(4)-2
=8-2
=6
2. 2((-2)^2)-(-2)
=2(4)+2
=8+2
=10
