The fastest pizza box folder can assemble 2 pizza boxes in 5 seconds. At this rate, how long would it take to assemble 20 pizza boxes?
Answers
Answer:
50 seconds in order to assemble 20 pizza boxes
Step-by-step explanation:
there are two ways to solve this the first way is divide 20 by 2 which is 10 and then multiply 10 by 5 the reason to this is because we know that for every 2 it takes 5 seconds.
the second way takes longer but you write:
2, 2, 2, 2, 2, 2, 2, 2, 2, 2,
5, 5, 5, 5, 5, 5, 5, 5, 5, 5,
so here were basically writing the number 2 10 times because when u count that u can see that it equals 20 and then since for every 2 boxes it takes 5 seconds u put the 5 under each 2 so then you would count the 5s, like 5, 10 15, 20... and so on and u will see that its 50 which means 50 seconds.

z-score for 11 minutes of advertising time is
Step-by-step explanation:
Z-scores measure the distance of any data point from the mean in units of standard deviations and are useful because they allow us to compare the relative positions of data values in different samples.
The z-score for any single data value can be found by the formula:
From the information given we know:
- Data value = 11 minutes
- Mean = 17 minutes
- Standard deviation = 2.7 minutes

D. Sec(0)= 13/5
Answers
Answer:
D. sec(a) = 13/5
Step-by-step explanation:
if sin(a) = 12/13, then cos (a) = 5/13, because of 5-12-13 triangles
sec(a) = 1/cos(a)
1/(5/13) = 13/5
sec(a) = 13/5

B = {∅, {1}, {1, 2}, {1, 2,3}, · · · , {1, 2, · · · , m}}
Answers
Answer:
m + 1
Step-by-step explanation:
Given set,
B = {∅, {1}, {1, 2}, {1, 2,3}, · · · , {1, 2, · · · , m}},
Since, the elements of S are,
{} , {1}, {1, 2}, {1, 2, 3}....... {1, 2,.....m }
Thus, every next set contains one more succeeding natural number than the previous set.
So, if the last set contains m natural numbers.
Then there are 'm + 1' sets in B ( m sets included ∅ )
Hence, the number of elements in B is 'm+1'
I.e. Cardinality of B is m + 1.

Step-by-step explanation:
the perimeter (the way one time around it) of a rectangle is
2×length + 2×width
length = 3×width
2×(3×width) + 2×width = 160
6×width + 2×width = 160
8×width = 160
width = 160/8 = 20 ft
length = 3×width = 3×20 = 60ft
