The question is incomplete:
Find the number of boxes needed, x, for 42 granola bars.
The table with the information is attached.
Answer:
The number of boxes needed for 42 granola bars is 7.
Step-by-step explanation:
Since the table shows that for 12 granola bars 2 boxes are needed, you can use a rule of three with this information to find the number of boxes needed for 42 granola bars:
12 granola bars → 2 boxes
42 granola bars → x
x=(42*2)/12
x=84/12
x=7
According to this, the answer is that the number of boxes needed for 42 granola bars is 7.
The answer is A!!! Hope that helped :)
yes sure, i learned this before so
1. a. make a proportion here, of percentage.
if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again,
cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
Answer:
the cyclists rode at 35 mph
Step-by-step explanation:
Assuming that the cyclists stopped, and accelerated instantaneously at the same speed than before but in opposite direction , then
distance= speed*time
since the cyclists and the train reaches the end of the tunnel at the same time and denoting L as the length of the tunnel :
time = distance covered by cyclists / speed of cyclists = distance covered by train / speed of the train
thus denoting v as the speed of the cyclists :
7/8*L / v = L / 40 mph
v = 7/8 * 40 mph = 35 mph
v= 35 mph
thus the cyclists rode at 35 mph
