Answer:
(a) 2.27 lb/$
(b) 0.10 mi/min
Step-by-step explanation:
<h3>(a)</h3>
Pounds per dollar is found by dividing pounds by dollars:
(25 lb)/($11.00) ≈ 2.272727... lb/dollar
The digit in the thousandths place is less than 5, so that digit and all digits to its right are dropped when rounding to hundredths.
2.27 pounds per dollar
__
<h3>(b)</h3>
Speed in miles per minute is found by dividing miles by minutes:
(6 mi)/(58 min) ≈ 0.103448... mi/min
Rounding to hundredths is done the same way as above.
0.10 miles per minute
_____
If the digit to the right of the place you're rounding to is 5 or more, then 1 is added in the place you're rounding to when digits to its right are dropped.
If x is the age and y is the diameter of the trunk, write the equation:
ax+b=y
We must solve for a and b with the given information.
If (x, y) is (1, 4), we have:
a+b=4
If (x, y) is (10, 25), we have:
10a+b=25
Multiply the first equation by 10 to get:
10a+10b=40
Subtract the second equation from this to get:
9b=25
Thus b=25/9. a=4-25/9=11/9, so our equation is 11x/9+25/9=y.
