Ian mailed a package that weighed 5.63 pounds.
Round the number to nearest tenth
First step :
Ones . Tenth hundredth
5 . 6 3
To round to nearest tenth we look at the number in hundredth place
3 is smaller than 5 so we replace 3 with 0.
Step 2: 3 in hundredths place is smaller than 0 . so no need to add 1 in tenths place. 6 remains the same in tenths place
5.63 rounded to the nearest tenth is 5.6

The exponential equation will be y = 10 (0.1)ˣ.
<h3>What is an exponent?</h3>
The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.
The table of data is given.
x f(x)
-2 128
-1 27
0 5
1 1
2 0.1
Then the equation will be
f(x) = abˣ
At x = 1, the value of f(x) is 1.
1 = ab ...1
At x = 2, the value of f(x) is 0.1.
0.1 = ab² ...2
Then from equations 1 and 2, we have
0.1 = b
Then the value of a will be
a = 1 / 0.1
a = 10
Then the exponential equation will be
y = 10 (0.1)ˣ

You put 15 over 65 is equal to 50 over x, then you multiply diagonally so 15x = 3250 then you divide both sides by 15 to get 216.67 which means 50 pencils equals 2.17 dollars
