Make each known side into a ratio like so...
75/6
(Because 75 is the shadow casted by the building, and 6 is the shadow casted by sarah)
and 50/x
(50 is how tall the building is and sarah's height is what needs to be found)
Therefore,
75 50
---- -----
6 x
Do cross products;
50 x 6 = 75 x X
300 = 75x
Divide by 75
x = 4ft
Answer:
x=k+c over 7
Step-by-step explanation:
7x-c+c=k+c
7x=k+c
divide both sides by 7
Answer:
glucose that is what i think but it looks not right for your letter.
Step-by-step explanation:
Point slope form
y-y1=m(x-x1)
m=slope
(x1,y1) is a point
(-5,-1)
x1=-5
y1=-1
m=-5/4
y+1=-5/4(x+5)
y=-5/4x-29/4
The additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number),[1] sign change, and negation.[2] For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive. Zero is the additive inverse of itself.
