Answer:
73
Step-by-step explanation:
Mean is the number of copiers combined / number of months
79 * 5 = 395
93 + 30 + 138 + 61 = 322
395 - 322 = 73
Answer:
x
^2 + 11 x + 30
Step-by-step explanation:
Expand the polynomial using the FOIL method.
x^2 + 6x + 5x + 30
Collect the like terms
x^2 + (6x + 5x) + 30
Simplify
x
^2 + 11 x + 30
Hope this helps :)
B infinite solutions,
Because both left hand and right hand sides are equal
Answer:
Part 1) 300 miles
Part 2) 420 miles
Part 3) 600 miles
Step-by-step explanation:
we have

where
d(x) is the distance in miles
x is the time in hours
Part 1) How many miles will he have traveled after 3 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=3 hours

For x=3, d(x)=300
That means -----> After 3 hours Carlos has traveled 300 miles at a constant speed of 60 mph
Part 2) How many miles will he have traveled after 5 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=5 hours

For x=5, d(x)=420
That means -----> After 5 hours Carlos has traveled 420 miles at a constant speed of 60 mph
Part 3) How many miles will he have traveled after 8 more hours?
we know that
To find the distance, substitute the value of x in the function
so
For x=8 hours

For x=8, d(x)=600
That means -----> After 8 hours Carlos has traveled 600 miles at a constant speed of 60 mph
Answer:
87.5%
Step-by-step explanation:
There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.
The number is students not trying out for football last Thursday is calculated as:
376 students - 47 students
= 329 students
The percent of 8th graders that did not try out for football is calculated as:
329 students/376 students × 100
= 329/376 × 100
= 87.5 %
