Tom travels along the M1 from Leicester to London which is a distance
of 143 miles.
10
He sets off at 8:25 and gets there at 10:15.
Did he break the 70mph speed limit of the M1?
Tom did not break the 70mph speed limit of M1.
What is speed?Speed can be defined as the rate of change of distance. The S.I unit of speed is m/s.
To know if Tom breaks the speed limit of the M1, we must first calculate Tom's speed and compare it to M1's speed limit.
Using the formula below,
s = d/t............... Equation 1Where:
s = Tom's speedd = distance from Leicester to Londont = time taken to travel from Leicester to LondonFrom the question,
Given:
d = 143 milest = 8:25 to 10:15 = 2 hours 10 munites = (2+10/60) = (2+0.17)t = 2.17 hours.Substitute these values into equation 1
s = 143/2.17s = 65.899 mph.Hence, Since Tom's speed is less than the M1 speed limit, Tom did not break the 70mph speed limit of M1.

Cameron earns four times as much as a tutor than a fast food worker. His sister only has one job because she earns one and a half times as much as a tutor than Cameron. Her weekly wage is $250 more than Cameron. How much does Cameron earn as a tutor?
Answer:
$500 per week.
Step-by-step explanation:
Let Cameron earns $x as a tutor.
As his sister earns one and a half times as much as a tutor, so, his sister earns $1.5x.
Since the weekly wage of Cameron's sister is $250 more than Cameron, so
[tex]1.5x=x+250[/tex]
[tex]\Rightarrow 1.5x-x=250[/tex]
[tex]\Rightarrow 0.5x=250[/tex]
[tex]\Rightarrow x=500.[/tex]
Hence, the weekly earning of Cameron is $500.

Answer:
[tex](4;3)[/tex]
Step-by-step explanation:
Add the two equations together
[tex]I+II: x+7y+2x-7y=25-13 \rightarrow 3x=12\rightarrow x =4[/tex]
At this point i'd rather replace x=4 in the first equation to get [tex]4+7y=25 \rightarrow 7y=21 \rightarrow y=3[/tex]
To keep eliminating you multiply the first by 2 and subtract the second
[tex]2\times I -II: 2x+14y-2x-(-7y)=50-(-13)\rightarrow 21y=63 \rightarrow y=3[/tex]
Two teachers compared the mean absolute deviation of the scores from the semester exam they gave to their students. Mrs. Alvarez's scores had a lower mean absolute deviation than Mr. Crawford's scores. What can we conclude? * 10 points A. Mrs. Alvarez's scores were lower than Mr. Crawford's scores. B. Mrs. Alvarez's scores were more spread out than Mr. Crawford's scores. C. Mrs. Alvarez's scores were less spread out than Mr. Crawford's scores. D. Mrs. Alvarez's scores were higher than Mr. Crawford's scores.
Answer:
C. Mrs. Alvarez's scores were less spread out than Mr. Crawford's scores.
Step-by-step explanation:
Mean Absolute Deviation is one of the Statistical measures which we can you to determine the variation that exist amongst a given set of data
Mean Absolute Deviation can be defined as how far or the distance between one set of data to another set of data.
The smaller the Mean Standard Deviation, the lower the degree of variation in the set of data. The data is less spread out
The larger the Mean Standard Deviation, the higher the degree of variation in the set of data. The data is Largely spread out
We are told in the question that:
Mrs. Alvarez's scores had a lower mean absolute deviation than Mr. Crawford's scores. Our conclusion would be that Mrs. Alvarez's scores were less spread out than Mr. Crawford's scores.

THIS IS IMPOSSIBLE!!!!!!!!!!!!!!!
Answer:
X is about 14.1
Step-by-step explanation:
Hi!
In order to solve this problem, we just have to take the square root of both sides:
x²=200
x times itself should equal 200.
And the answer is
x≈14.1

Answer:
4680 dollars
Step-by-step explanation:
Hello, I'd love to help you!
We know that:
-Original price is 7200 dollars
-Manuel only paid for 65% of it
-> think of it this way: think of the overall price as a pie; Manuel only ate 65% of it
To calculate how much Manuel paid, we can multiply 7200 times 0.65 (percentage in decimal form), which equals 4680 dollars.

if u use deductive reasoning you'll know. so u know looking at the line it's a positive slope cause the line is going up and u know the y intercept is positve 1 so u know it will be +1 knowing this and going through the answer choices D is the only one that fits that!
The correct explanation of the graph is;
y = 3/2 x + 1
Option D is true.
What is Equation of line?
The equation of line with slope m and y intercept at point b is given as;
y = mx + b
Given that;
The graph is shown in figure.
Two points on the graph are (2, 4) and (4, 7).
Now, Take two points on graph and find the slope of the graph as,
Two points on the graph are (2, 4) and (4, 7).
Hence, Slope of graph = (7 - 4) / (4 - 2)
= 3/2
Thus, Slope of graph is 3/2.
Since the slope of graph is same as slope of equation.
Hence, In option D;
The equation is given as;
y = 3/2 x + 1
Slope of equation is find as differentiate with respect to x,
Slope of equation is;

There are 2 different maps of California. The scale on the first map is 1cm to 20km. The distance from Fresno to San Francisco is 15km. The scale on the second map is 1 cm to 100 km. What is the distance from Fresno to San Francisco on the second map?
Answer:
75 km
Step-by-step explanation:
Given the following :
Scale on first map = 1cm to 20 km
Distance fromFresno to San Francisco = 15km on first map
Scale on 2nd map = 1cm to 100 km
1cm / 20km = 15km
Let of Distance from Fresno to San Francisco on 2nd map = d
1cm / 100km = d
1 : 20 = 15
1 : 100 = d
20/ 100 = 15/d
1/5 = 15/d
d = 15 * 5
d = 75 km

Step-by-step explanation:
Carlos rented a truck for one day. There was a base fee of $19.99, and there was an additional charge of 86 cents for each mile driven. Carlos had to pay $201.45 when he returned the truck. For how many miles did he drive the truck?
Answer: 211 miles
Step-by-step explanation: An equation for this could be:
base fee + additional charge (miles driven) = total charge
19.99 + 0.86(x) = 201.45
0.86(x) = 201.45 - 19.99
0.86(x) = 181.46
x = [tex]\frac{181.46}{0.86}[/tex] = 211 miles
