Multiply 120 by 0.40 to get 40%:
120 x 0.40 = 48
So 48 is 40% of 120
Let x represent the amount of lawn mowers that were manufactured
The company has to pay $34,816 before they even make any lawn mowers plus $388 per lawn mower.
((34816+388x)/x)=660
34816+388x=660x
34816=272x
X=128
Therefore, there were 128 lawn mowers manufactured
Put the answer choice numbers where the x’s are in the equation and then solve. The ones that are equal to 0 once solved will be your answer
Answer:
175
Step-by-step explanation:
for 10 water bottles its 35 dollars so you multiply 10 by 5 and its 50. so you multiply 35 by 5 and get 175.
Answer:
5.6 days
Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229
Formula is given as;
N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25
e^(-0.1229t) = 0.5
(-0.1229t) = In 0.5
-0.1229t = -0.6931
t = -0.6931/-0.1229
t = 5.6 days
