Mr. Richards a teacher at crosstown Elementary school, plans to take 25 students on a school trip. Here are some more facts about the trip: Only one bus is needed for the field trip, the bus company charges $6.50 per mile. The school will pay $300 for the trip, teachers go free, and each student pays the same amount. You will find the cost of this field trip. What is the final cost for all students to attend this field trip?
Incomplete question. The remaining part of the question reads;
Here are the places they could visit:
Big City Zoo> 36 miles from Crosstown; Entrance Fee: $2.5Prison Museum> 30 miles from Crosstown; Entrance Fee: $6.75Space Science> 10 miles from Crossword; Entrance Fee: $11.25I calculated the cost of going to 'Big City Zoo and Space Science'.
Answer:
Big City Zoo = $3.86
Space science = $1.35
Step-by-step explanation:
For Big City Zoo:
Entrance fee: $2.5 x 25 = $62.5
Charges per mile: $6.5 x 36 = $234
Total cost of trip= $296.5
Final cost for all students to attend this field trip = $296.5 - $200 = $96.5. Meaning each student pays $3.86 (or $96.5/25 students).
For Space Science:
Entrance fee: $6.75 x 25 = $168.75
Charges per mile: $6.5 x 10 = $65
Total cost of trip= $233.75.
Final cost for all students to attend this field trip = $233.75 - $200 = $33.75. Meaning each student pays $1.35 (or $33.75/25 students).
Gayle made a
baby quilt using 24 equal squares. What
are the dimensions of 1 square? Describe
two different ways to find the answer.
Answer:
[tex]Measurement = 0.75ft[/tex]
Step-by-step explanation:
See attachment for complete question
Method 1:
Considering the width and length of the quilt
Given
[tex]Number\ of\ squares = 24[/tex]
Required
Determine the dimension of 1 square
The width of the quilt is 4.5ft and there are 6 squares in that dimension.
Each measurement is calculated as thus:
[tex]Measurement = \frac{4.5ft}{6}[/tex]
[tex]Measurement = 0.75ft[/tex]
Or
The length of the quilt is 3ft and there are 4 squares in that dimension.
Each measurement is calculated as thus:
[tex]Measurement = \frac{3ft}{4}[/tex]
[tex]Measurement = 0.75ft[/tex]
Method 2:
Calculate the area of the quilt.
[tex]Area = 4.5ft * 3ft[/tex]
[tex]Area = 13.5ft^2[/tex]
The area of 1 of the 24 squares is calculated by dividing the total area by number of squares
[tex]Area = \frac{13.5ft^2}{24}[/tex]
[tex]Area = 0.5625\ ft^2[/tex]
Represent the dimension of individual square with L
Area of a square is:
[tex]Area = L * L[/tex]
This gives:
[tex]L * L = 0.5625[/tex]
[tex]L^2 = 0.5625[/tex]
Take square root of both sides
[tex]L = \sqrt{0.5625[/tex]
[tex]L = 0.75ft[/tex]
Hence, the dimension of each square is 0.75ft
How do you find the equation of the circle given center at (1,-3), and radius 10?
Answer:
note: all the twos are to the power100=(x−1)2(y+3)
Step-by-step explanation:
Suppose the centre of the circle was at the origin (where the x axis crosses the y axis). Then the equation would be:
r2=x2+y2
The reason for this format is that the length of the radius (which is of fixed length) can be related to x and y by Pythagoras. However, the circle centre is not at the origin. It is at
(x,y)→(1,−3)
So we can mathematically make this work by 'theoretically' moving the actual centre to a new centre located at the origin.
Thus we would have:
r2=(x−1)2+(y−(−3))2
r2=(x−1)2+(y+3)2
But the radius is 10 so we have
(10)2=(x−1)2+(y+3)2
100=(x−1)2+(y+3

Pluto has an average distance from the sun of 3.6 x 10^8 miles venus has an average distance from the sun of 9.0 x 10^6. How many times greater is pluto's average distance from the sun than venus?
Answer:
40 times greater
Step-by-step explanation:
Given the following:
Pluto average distance from the sun Ps = 3.6 x 10^8 miles
venus average distance from the sun Vs = 9.0 x 10^6miles
Take the ratio:
Ps/Vs = 3.6 x 10^8/9.0 x 10^6
Ps/Vs = 0.4*10^{8-6}
Ps/Vs = 0.4*10²
Ps/Vs = 40
Ps = 40Vs
Hence the pluto's average distance from the sun is 40 times greater than that of venus

lays an average of 56 eggs at one time.
Find the total volume of these eggs, to
the nearest tenth cubic centimeter.
I’ll give brainliest if it right!
HELPPPPPPPPPPPPPPP
Answer:
A) 1366.4 cm
Step-by-step explanation:
As, volume of a sphere = 4/3 x pi x r^3
Radius= Diameter /2
R = 3.6/2 = 1.8
So,volume of 1 egg = 4/3 x 3.14 x 1.8^3
= 24.43 = volume
So volume of 56 such eggs = 24.43 x 56 = 1,366.4 cm^3

Sausages come in packets of 7. Bread rolls come in packets of 5. Dan wants to buy enough packs of sausages and rolls so that there are an equal number of sausages and rolls. What is the minimum number of sausages and rolls he needs to buy?
Answer:
5 packs of sausages7 packs of rolls
Step-by-step explanation:
You need to find the common multiple.
5 x 7 = 35.
We know that before this there is no other common multiple becuase 7 does not multiply to a number that ends with a 0 or 5 until 35.
So, he will need to buy:
- 5 packs of sausages
- 7 packs of rolls
Answer:
7 packs of rolls
5 packs of sausages
Step-by-step explanation:
The easiest way to solve this question is to make a table with 3 columns
Rolls 5 10 15 20 25 30 35
Sausages 7 14 21 28 35 42 49
# packs 1 2 3 4 5 6 7
Looking at the table you can see that the first number that matches up is 35 so looking at that point we would need 7 packs of rolls and 5 packs of sausages.

Find the distance between 5 + 4i and 9 + 3i.
Answer:
Distance = √17
Step-by-step explanation:
We are looking for the distance between 5 + 4i and 9 + 3i.
This is as equal to saying we have two points in the plane, whose coordinates are; (5, 4) and (9, 3)
Distance between the 2 points will be;
D = √[(5 - 9)² + (4 - 3)²]
D = √(16 + 1)
D = √17

Light travels at a rate of approximately 186,000 miles per second. The North Star is approximately 460 light-years away from Earth. (A light-year is the distance light travels in one year.) How many yearswould it take a rockettraveling at 1 billion miles per hour to reach the North Star?
Answer:
0.0017 years
Step-by-step explanation:
Distance of North Star from Earth = 460 light years
A light year is the distance traveled by light in one year.
As per given statement:
Distance traveled by light in one second = 18600 miles
Distance traveled by light in one year ([tex]60 \times 60 \times 24\times 365[/tex]) = 18600 [tex]\times[/tex] 31536000 miles = 14506560000 = 14.51 [tex]\times[/tex] [tex]10^9[/tex] miles
We know that:
1 billion = [tex]10^9[/tex]
Therefore, 14.51 [tex]\times[/tex] [tex]10^9[/tex] miles = 14.51 billion miles
Also, it is given that speed of rocket = 1 billion miles per hour
Formula to represent relationship between Speed, Distance and Time is given as:
[tex]Distance = Speed \times Time[/tex]
[tex]Time = \dfrac{Distance}{Speed}[/tex]
[tex]Time =\dfrac{14.51\ billion\ miles}{1\ billion\ per\ hour}\\\Rightarrow Time = 14.51\ hours[/tex]
OR
0.0017 years

The population of a town is increasing at a constant rate of 4.7% each year. At the beginning of 2010 the population was 42,000. Find the size of the population at the beginning of 2016. Give your answer to 3 sf.
Answer:
The population at the beginning of 2016 is 55,326.
Step-by-step explanation:
Giving the following information:
Population 2010 (PV)= 42,000
Growth rate (g)= 4.7% = 0.047
Number of years (n)= 6 years
To calculate the population at the beginning of 2016, we need to use the following formula:
FV= PV*(1+g)^n
FV= 42,000*(1.047^6)
FV= 55,326
The population at the beginning of 2016 is 55,326.

How many solutions does the equation 3x − 7 = 4 + 6 + 4x have?
Answer:
one solution
Answer: The given equation 3x − 7 = 4 + 6 + 4x has one solution.J
Step-by-step explanation:
Answer:
One solution (x=17).
Step-by-step explanation:
First, we combine like terms and numbers (if we can). This leaves us with the equation 3x - 7 = 10 + 4x. Now, we add 7 to both sides. Now, we have the equation 3x = 17 + 4x. Next, we subtract 4x from both sides. This gets us -1x=17. We can simplify that to -x=17. Now, we divide both sides by -1 to make -x positive. This gets us x=-17. That means there is only one solution. I hope this helps!
