20:12
i think. 20 being the number of total students to 12 which is the number of boys
Answer:
first do 58-4 which is 54 then do 54/ 9 which is 6 so the number is 6
Answer:
$11.13
Step-by-step explanation:
$7.00 + $3.50 = $10.50
6% of $10.50 is $0.63
$10.50 + 0.63 = $11.13
27-5 = 22
22/11 = 11
there are 11 boys at the party
expression = b+5
Answer: 2.79 hours.
Step-by-step explanation:
Given that the function for the learning process is T(x) = 2 + 0.3 1 x , where T(x) is the time, in hours, required to produce the xth unit
To calculate the time for the new worker to produce 10 units, substitute 10 for x in the equation above.
T(x) = 2 + 0.31 (10)
T(x) = 2 + 3.1
T(x) = 5.1 hours
To calculate the time for the new worker to produce 19 units, substitute 19 for x in the equation above.
T(x) = 2 + 0.31(19)
T(x) = 2 + 5.89
T(x) = 7.89 hours
The time required for a new worker to produce units 10 through 19 will be
7.89 - 5.1 = 2.79 hours
