Answer:
Equation: y = 15.5x
Step-by-step explanation:
Given that:
Time earns $31 for 2 hours
$46.5 for 3 hours
$62 for 4 hours
We will find unit rate first.
Unit rate =
= $15.5 per hour
Now,
Let,
x be the number of hours
y be the total money earned by Tim
Total earning = Per hour rate * Number of hours
y = 15.5x
Hence,
Equation: y = 15.5x
Answer:
161.63 tons
Step-by-step explanation:
Cement used per mile = total cement used / total miles
646.5 tons / 4 = 161.625 tons
161.63 tons to the nearest hundredth
the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero
the thousandth term is 5, so 1 would be added to 2
Answer: There are 15 boards that she can make from a 5 ft board.
Step-by-step explanation:
Since we have given that
Length of a board = 5 ft
Length of board she can make from the above board is given by

We need to find the number of boards she can make from a 5 ft board.
According to question,

Hence, there are 15 boards that she can make from a 5 ft board.
Answer:
x=11
Step-by-step explanation:
Since this is a 90º angle, 46º+(4x)º has to equal 90º, and you can make and solve an equation for this:
46+4x=90
4x=44
x=11
Check:
46+4x=90
46+4(11)=90
46+44=90
90=90
