Answer:
A. -44 4/9
Step-by-step explanation:
First find the decimal values of both fractions:
7/10 is 7 divided by 10 so:
= 0.70
3/5 is 3 divided by 5 so:
= 0.60
60 minutes is one hour (since the question said that Lola rides the bike for 7/10 and 3/5 of an hour)
Now we use these to find how many minutes:
To find 0.70 (or 7/10) of 60 minutes, you multiply 60 x 0.70
= 42 minutes on Saturday
To find 0.60 (or 3/5) of 60 minutes, you multiply 60 x 0.60
= 36 minutes on Sunday
Now to find how much longer she rode her bike on Saturday than Sunday, you subtract the two numbers:
42 - 36
= 6
Therefore, Lola rode her bike for 6 minutes more on Saturday than on Sunday.
A. 81 because the formula for surface area is 2(wl + hl + hw)
So the formula filled in is 2( 1 1/2 x 3 + 2 x 3+2 x 1 1/2 ) = 27
and 27 x 3 = 81
The linear model for the daily cost is C(x) = $1378 + $1.83(x).
The cost of producing 267 widgets is $1,866.61
<h3>What is the cost of producing 267 widgets?</h3>
Fixed cost is the cost the remains constant with the number of widgets produced. Variable cost increases with the number of widgets produced. Daily cost is the sum of fixed cost and variable cost.
Fixed cost = fixed cost + (variable cost x number of widgets)
C(x) = $1378 + $1.83(x).
C(x) = $1378 + $1.83(267) = $1,866.61
