Kenji drives 18.4 miles in 16 minutes. He passes a sign, which gives the speed limit as 60 mph. By how much, in mph, did Kenji's average speed exceed the speed limit?
Answers
The amount of speed by which kendri exceeded the speed limit is; 9 mph
We are given;
Distance; d = 18.4 miles
Time; t = 16 minutes = (16/60) hours
Now, the formula for speed is;
Speed = distance/time
Thus, let's Calculate kenji's speed;
Kenji's speed = 18.4/(16/60)
Kenji's speed = 69 mph
We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;
69 - 60 = 9 mph

Answers
Answer:
they are parallels
Step-by-step explanation:
they have the same slope but different y intercepts so they are parallel
Answer:
Parallel
Step-by-step explanation:
First, you should put the second equation in slope-intercept form, it would be y=3x+8.
If two lines are parallel they will have the same slope. If two lines are perpendicular the slopes will be the negative reciprocals of each other. The slopes of these two lines are the same so they are parallel.

-4x+5 + -13x+39=180 angle measure

Step-by-step explanation:
−4x+5−13x+39=180
Step 1: Simplify both sides of the equation.
−4x+5−13x+39=180
−4x+5+−13x+39=180
(−4x+−13x)+(5+39)=180(Combine Like Terms)
−17x+44=180
−17x+44=180
Step 2: Subtract 44 from both sides.
−17x+44−44=180−44
−17x=136

Examine the following tables of ordered pairs and identify which relations are functions.Select two that apply
Answers
Answer:
Step-by-step explanation: B
The tables of ordered pairs representing relations that are functions are: A and C.
What is a Function?If a table of ordered pairs of a relation has each x-value relating to exactly one y-value, then the relation is a function.
Table B and D do not apply to this rule. Table A and C have each of its x-values paired with exactly one y-value.
Therefore, table A and C represent functions.

2. Solve: 2p+4= - 50
Answers
2p + 4= -50
=> 2p = -50-4
=> 2p = -54
=> p = -54/2
=> p = -27
explanation: subtract 4 from both sides,
(4+(-4)) cancels out so you do (-50(-4)) which gives you (-54). Your equation should look like 2p=-54, then you divide 2 from both sides, 2p divided by 2, leaving the “p” variable by itself, while you also divide -54 by 2, which leave you with the final answer: p=-27
the average screen time for middle school students is 240 minutes per day. In 2020 students went into virtual learning and the average screen time is 70 percent longer. What is the total percent of screen time this year?
Answers
Answer:408=screen time
Step-by-step explanation:240+168 70%=168
make sure to like with the heart
Answer:
I believe 408 minutes a day
Step-by-step explanation:
So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.
ex.
240/10 = 24
24x7=168
240+168= 408
to do with 100s like 73% then divide the whole by 100 :)
