Answer:
0.27 lt/s
Step-by-step explanation:
80 liters in 5 minutes
5 minutes are 300 seconds (5x60)
We know how many seconds we need to fill up the tank (300 seconds for 80 liters). Now we need to know how many liters we can fill up in 1 second, as the question requires "liters per second".
80 lt / 300 sec
X lt / 1 sec
80 x 1
---------- = X
300
X = 0.2666666...
X = 0.27 lt / s

Which equation has a solution of 4? Select all that apply. A 12x = 3 C10 + x = 14 B 6x = 24 DX-4 = 8
Answer:
C and B
Step-by-step explanation:
A. 12x = 3, x =1/4
C. 10 + x = 14, x = 4
B. 6x = 24, x =4
D. x -4 = 8, x =12
Only the expression mentioned in B and C gives the solution as 4. Options B and C are correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
A
12x = 3

12x = 3
x = 3 / 12
x = 1 / 4
Similarly simplifying all the expressions gives,
B. x = 4
C. x = 4
D. x = 12

what is the 37th term of the arithmetic sequence with the first term -39 and the common difference of 8
257
241
227
249
Answer:
249
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
an = a1+d(n-1)
a1 is the first term so a1 = -39
d is the common difference so d = 8
n is the term number so n = 37
a37 = -39+8(37-1)
= -39+8(36)
= -39+288

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that camp orders 200 badges. The plan to give 25 badges to counselors and ordered at least 3 badges for each camper.
Therefore, the difference would be;
200-25= 175
Then we get;
175÷3= 58 1/3
Hence, There are 58 1/3 campers
