Dogs. Cats.
4. To. 9
64. To. ?
I solved this by guess-timating, and i got it right. I know that 8*8=64 and 4*2=8 8*2=16, and i checked and got 16*4=64.
Since you do:
Dogs:4 * 16= 64
You have to do:
Cats:9 * 16= # of cats
And 9*16=144,
So there are 144 cats at the kennel
This will involve finding an arctangent.
We'll consider the woman's height as the "opposite" side of a triangle and the shadow as the "adjacent" side. The angle that the Sun makes equals the arc tangent of that angle.
tan (Sun's angle) = 71" / 36"
tan (Sun's angle) =

1.9722222222
</span>

when we determine the arc tangent of 1.9722222222, it will equal the Sun's angle.
arc tangent of 1.9722222222 = 63.113 degrees
8(4x+5)=136
Multiply the number outside of the parenthesis(8) with the numbers inside the parenthesis(4x and 5).
32x+40=136
Subtract 40 from both sides
32x=96
Divide both sides by 32 so the only thing remaining on the side of the variable is only the variable itself.
Final Answer: x= 3
Answer:
y-5=-3(x-1) simplified: y=-3x+8
Step-by-step explanation:
y-y1=m(x-x1)
plug in point and slope given
y-5=-3(x-1)
y=-3x+3+5
y=-3x+8
