Answer:
72 signs
Step-by-step explanation:
90 min = 1.5 hour
6 hours hangs 6/1.5 * 18 signs = 72
Answer:
The number will be -63
Step-by-step explanation:
Here, we want to give the number of the chosen 25th student
We can see that the numbering follows an arithmetic sequence where a = 9 and d which is the common difference is (6-9) = -3
Mathematically, we can calculate the nth term using the equation below;
Tn = a + (n-1)d
in this case, n = 25, a = 9 and d = -3
So we have
Tn = 9 + (25-1)-3
Tn = 9 -3(24)
Tn = 9-72
Tn = -63
They provide all the needed data...
n + d + q = $3.00 (they provide a ratio)
3:2:1 = $3.00 (let's enter the value of each)
3(.05) + 2(.10) + 1(.25)
.15 + .20 + .25
.60 = is the value of the ratio
let's divide the $3.00 by the .60 to get 5
let's now multiply the value of 5 to the ratio and solve the question...
3(5): 2(5): 1(5)
15 nickels
10 dimes

you would have 32 multiplication and 16 addition I believe because.
