A truck's gas tank holds 50 gallons of gas. if one gallon takes 30 seconds to pump, how many minutes will it take to fill the em
umka2103 [35]
To find how long it will take to fill the tank, you can use the idea that every 30 seconds will get you one gallon closer to being full.

This means to fill 50 gallons, you will need 50 groups of 30 seconds.  

50 x 30 = 1500 seconds

1500/60 = 25 minutes.

It will take 25 minutes.  

You could also think of it as filling 2 gallons every minute.  It would take 25 of these.

DedPeter [7]

Answer:

use own words

Step-by-step explanation:

An expression is just a mathematical phrase. In this tutorial, you'll learn about two popular types of expressions: numerical and algebraic expressions. A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables.

in mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)

Suppose you have a random sample of 50 of these animals. What is the probability that the mean life span of the sample group is
katrin2010 [14]

In what I know of this problem and what you told me I think there is a 1/2 chance!

think about it, if the life span is 15 years old with standard deviation of 3 then that means we can have bats from 12~18 years old and the mean of the 50 numbers can be anything between that depending on the results we got. Then half of values in interval 12~18 is over 15 which gives it a 1/2 probability!
