Answer: 74
<u>Step-by-step explanation:</u>
Homework + Quiz + Test + Final Exam = 70
67(10%) + 62(15%) + 71(50%) + x(25%) = 70
6.7 + 9.3 + 35.5 + 0.25x = 70
51.5 + 0.25x = 70
0.25x = 18.5
x = 74
The minimum score is 74.
Answer:
The first one is x=2 and the second one is x=2/5 or 0.4
Step-by-step explanation:
Answer:
347 is the initial spider population
Step-by-step explanation:
y = ab^x
is the formula for exponential growth and decay
a = the initial value
b is the growth or decay rate
b>1 it is the growth rate (b-1) is the percent
0<b<1 it is the decay rate (1-b) is the percent
y = 347(1.2)^x
347 is the initial spider population
(1.2-1) = .2 = 20 % growth rate
Bag weight 1.8 kg
Golf ball weight: 45g
1 kg = 1000g
Total bag weight in grams = 1.8 x 1000 = 1800g
total bag weight / golf ball weight = total balls in bag
1800 / 45 = 40
Total balls in bag = 40.
