Step-by-step explanation:
When Mr. Johnson drives from Cambridge to Newton it takes
him 15 minutes travelling at a speed of 80 miles per hour. Mrs.
Johnson drives from Cambridge to Newton and leaves 10
minutes after Mr. Johnson but travels at a speed of 100 miles per
hour. Who will arrive first? By how many minutes?
Answer:
Mr. Johnson completed his travel in 15 minutes. But Mrs. Johnson leaves 10 minutes after he does. And to add her 12 minutes travel time, that means Mrs. Johnson will arrive in 22minutes.
Step-by-step explanation:
First, we need to find the distance (d) that Mr. Johnson traveled to be able to compute Mrs. Johnson's travel time.
To be able to do that, use the formula d = (s)(t).
d = (80miles/hr)(15mins)
d = (80miles/hr)(0.25hr)
d = 20 miles
Now that we know the distance from Cambridge to Newton, we can use this value to calculate the time Mrs. Johnson needs to complete her travel.
Using the formula t = (d)/(s);
t = (20miles)/(100miles/hr); we get:
t = 0.2hr or 12minutes

Lana and Jeff each randomly surveyed 15 students about their favorite types of movies. Are these samples representative of the school population? Explain.
A. No, the samples are not large enough to be representative.
B. Yes, both samples are random, so they are representative.
C. No, the samples might include some of the same people, so they are not representative.
D. Yes, the samples do not include the same people, so they are representative.
Answer:
The answer is B.
Step-by-step explanation:
You only surveyed 15 people out of what could be 300. The samples is too little because the more you survey the more accurate it will be.

Answer:
[tex]V = \pi (2.5)^2h[/tex]
Step-by-step explanation:
The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.
The equation is now:
V = π(2.5)^2h
This is the answer.
[tex]V = \pi (2.5)^2h[/tex]

Answer:
8( 3 + 7)
Step-by-step explanation:
I prommise this one is correct
8 is the GCF of 24 and 56
if you mutiply 3 by 8 it would equal 24
and if you mutiply 7 by 8 it would equal 56
which would leave you with 24+ 56
Answer:
8(3+7)
Step-by-step explanation:
First we list the factors of 24:
1,2,3,4,6,8,12,24
Now we list the factors of 56:
1,2,4,7,8,14,28,56
As we can see 8 is the highest number in both lists so this would mean a = 8
To factor 24+56 to 8(b+c) :
We do 24÷8 = 3 = b
and 56÷8 = 7 = c
So our final answer is 8(3+7)

Step-by-step explanation:
2) [tex]8\leq \frac{w}{8}[/tex]
Multiply 8 on both sides to isolate w
[tex]8\leq \frac{w}{8}\\(8)8\leq \frac{w}{8}(8)\\64\leq w[/tex]
3) [tex]18 < f-2[/tex]
Add 2 on both sides to isolate f
[tex]18 < f-2\\18 +2 < f-2+2\\20 < f[/tex]
4) [tex]\frac{y}{12} < 4[/tex]
Multiply 12 on both sides to isolate y
[tex]\frac{y}{12} < 4\\\frac{y}{12}(12) < 4(12)\\y < 48[/tex]
5) [tex]6 < r+6[/tex]
Subtract 6 from both sides to isolate r
[tex]6 < r+6\\6-6 < r+6-6\\0 < r[/tex]
6) [tex]10 > 7+x[/tex]
Subtract 7 from both sides to isolate x
[tex]10 > 7+x\\10-7 > 7-7+x\\3 > x[/tex]
7) [tex]n+1\leq 6[/tex]
Subtract 1 from both sides to isolate n
[tex]n+1\leq 6\\n+1-1\leq 6-1\\n\leq 5[/tex]
8) [tex]9x\leq 18[/tex]
Divide both sides by 9 to isolate x
[tex]9x\leq 18\\\frac{9x}{9} \leq \frac{18}{9} \\x\leq 2[/tex]
9) [tex]p+3 > 9[/tex]
Subtract both sides by 3 to isolate p
[tex]p+3 > 9\\p+3-3 > 9-3\\p > 6[/tex]
10) [tex]4\leq \frac{c}{3}[/tex]
Multiply both sides by 3 to isolate c
[tex]4\leq \frac{c}{3}\\(3)4\leq \frac{c}{3}(3)\\12\leq c[/tex]
11) [tex]k-13\leq 7[/tex]
Add 13 to both sides to isolate k
[tex]k-13\leq 7\\k-13+13\leq 7+13\\k\leq 20[/tex]
12) [tex]15 > 5x[/tex]
Divide both sides by 5 to isolate x
[tex]15 > 5x\\\frac{15}{5} > \frac{5x}{5} \\3 > x[/tex]
What fraction of the bones in a typical human body are in the skull, face, and ears? Show how you found your answer.
Answer:
28/206 or the simplest form would be 14/103
Step-by-step explanation:
Basically, you add the skull, face, and ears and you get a number which is 28 and the total of the bones is 206 if you add all of the numbers and if you want to simplify you divide both of the numbers/the numerator and denominator by 2 and you get 14/103.
The value of fraction of the bones in a typical human body are in the skull, face, and ears is,
⇒ 28 / 206
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
The table shown the bones in a typical human body.
Hence, Number of the skull, face, and ears bones is,
⇒ 8 + 14 + 6
⇒ 28
And, Total number of bones is,
⇒ 206
Thus, The value of fraction of the bones in a typical human body are in the skull, face, and ears is,
⇒ 28 / 206

Scott and Isaac went to the school carnival. Scott ride on 5 rides and played 4 games. Isaac rode on 7 rides played 2 games. If Scott payed 19 tickets and Isaac payed 23 tickets, how many tickets did a ride cost?
Answer:
The cost of the rides are 3 tickets
And 1 ticket per game
The ride and game cost 3 tickets and 1 ticket for each respectively.
Step-by-step explanation:
Step 1 of 5
Let a be the number of tickets per ride costs. And b be the number of tickets per game costs.Thus from the given, we get the equations. For Scott, 5a+4b=19 For Isaac, 7a+2b=23
Step 2 of 5
Multiplying the equation 2 by 2, we get 5a+4b=19→1 14a+4b=46→2
Step 3 of 5
By subtracting both the equations, we get
(−)5a+4b=1914a+4b=46
_____________
−9a =−27
a=−27−9⇒a=3
Step 4 of 5
Substituting the above value in the equation 1, we get5(3)+4b=1915+4b=194b=19−154b=4b=44⇒b=1
Step 5 of 5
The solution is (3,1).The cost of the rides is 3 tickets per ride.The cost of the games is 1 ticket per game.

When soccer games are tied at the end of overtime, they are decided by penalty kicks. Each team gets `5` kicks. A coach knows that her team typically makes a penalty kick about `60\%` of the time. She decides to run a simulation of this situation. Based on these results, estimate the probability that the team makes `4` or more penalty kicks.
I need help!
Answer:
33%
Step-by-step explanation:
if you add the amount of penalty kicks in 4 or more, it is 33 and total of all penalty kicks is 100 so it probability is 33/100= 33%
A submarine submerges from the surface of the sea at the rate of 10 m/min. How long will it take to reach 300 m below the sea level
Answer:
answer is 300m/30min
Step-by-step explanation:
300\10=30
Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.
How long will it take the submarine to reach 300 m below the sea level?Using the expression Time = distance / speed.
Given that;
Speed = 10m/minDistance = 300mTime = ?Time = distance / speed
Time = 300m / 10m/min
Time = 30 minutes
Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.

What is the measure of the scale down below
Answer:
58 degrees
Step-by-step explanation:
It shows a square which means it is a right angle / 90 degrees. So that means because 32 degrees is already there the equation is 90 - 32 = 58 degrees.
Answer:
58 degrees
Step-by-step explanation:
A right angle is always equal to 90 degrees. So, Angle XOY (32 degrees) plus angle YOZ (x degrees) has to equal 90.
32 + x = 90
32 + x (- 32) = 90 (- 32)
x = 58
Therefore, x equals 58 degrees. I hope this was helpful! Have a lovely day!!! :D

Answer:
c=42
Step-by-step explanation:
First you would find out how much you would add to 45 to give you 66. Which is 21. Then you double it, so when you put it over the two it looks like this 42/2. So when you reduce the fraction you get 21. Hence 21+45=66.
Hope this helps!
Answer:
C = 42
Step-by-step explanation:
½ c + 45 = 66
½ c + 45 − 45 = 66 − 45
2 × (½ c) = 2 × 21
C = 42

What is the surface area of the cylinder. Use 3.14 as pi.
Answer: 376.8 cm^2
Step-by-step explanation:
The formula for the surface area of a cylinder is A = 2prh +2pr^2
When:
A = surface areap = value of pi (3.14 in this case)r = radius (= 1/2 diameter)h = heightWhen we substitute our values, we get the equation
A = 2(3.14)(4)(11) + 2(3.14)(4^2)
Now, we just multiply, square, and add our numbers to find A
A = 2(3.14)(4)(11) + 2(3.14)(4^2)
A = 2(3.14)(44) + 2(3.14)(16)
A = (6.28)(44) + (6.28)(16)
A = 276.32 + 100.48
A = 376.80
Because the hundredths place is a 0, we don't need to round.
A = 376.8
The unit is in centimeters. Area, and surface area by extent, are written in cm^2 (centimeters squared)
A = 376. 8 cm^2
Final answer: A = 376.8 cm^2
