Answer:
6
Step-by-step explanation:
We want to evaluate:
8a-1+0.5b
When a=1/4 and b=10.
We simply substitute the given values of as and b into the given expression,
The value of the expression is 6 for the give values of a and b.
Marlon asks a friend to think of a number from 5-11. What is the probability that marlins friend will think of the number 9
1 answer:
Answer:
14.29% probability that Marlon's friend will think of the number 9
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
There are 7 numbers from 5 to 11(5,6,7,8,9,10,11)
9 is one of them
So
14.29% probability that Marlon's friend will think of the number 9

I take it you meant θ angle, anyway.
we know the tan(θ) = -4/7... alrite, we also know that 270° < θ < 360°, which is another to say that θ is in the IV quadrant, where the adjacent side or "x" value is positive whilst the opposite side or "y" value is negative.

Answer:
(a)
(b)
The distance traveled in 30 seconds is 45 miles
(c)
It takes 85 seconds to go 12.75 miles
Step-by-step explanation:
we are given
An airplane is flying from New York City to Los Angeles
d is the distance traveled in miles
t is time in second
we have equation as
(a)
we have to find speed
we can see that our distance equation is in linear form
For finding speed, we can compare our equation with equation of line
and slope of the line will be speed
because slope is the rate of change
where m is slope
so, we can compare
and we get
so,
(b)
we can plug t=30 and find d
miles
so, The distance traveled in 30 seconds is 45 miles
(c)
we can set d=12.75 and solve for t
So,
It takes 85 seconds to go 12.75 miles
