The distance from the person to the mirror is 5 ft. The distance from the mirror to the giraffe is 15 ft.
15/5 = 3
Multiply the height of the person by 3:
5 ft = 60 inches 60+3 = 63 inches
63 x 3 = 189 inches
189/12 = 15.75 ft = 15 feet 9 inches
The giraffe is 15 ft 9 inches tall
Answer:A
Step-by-step explanation:
0=-2x^2+x+3
-2x^2+x+3=0
a=-2 b=1 c=3
Answer: Choice D. P = i/rt
This is the same as saying P = i/(rt). The parenthesis are preferred in my opinion to indicate we have rt in the denominator and not just r.
======================================
Explanation:
In the original equation, prt is the same as p*r*t. So we multiply p, r and t to get prt.
This can be thought of as p*(rt). To isolate p, we undo the multiplication done to the variable p. We will divide both sides by rt to get
i = prt
i = p*(rt)
i/(rt) = p*(rt)/(rt) ... dividing both sides by rt
i/(rt) = p
p = i/(rt)
Answer:
an independant variable dosent depend on any thing and a dependant variable depends on
if you rode a paddle boat for 30 min it cost 10 dollars
the 30 min is the independant variable and the 10 dollars is the dependant variable bc if u wanted to ride for longer than 30min you will have to pay more money therefore the cost depends on the time and time is independent bc the dosent depend on anything
