Two types of tickets are sold to a play. Floor seats cost $45 each and balcony seats cost $25 each. A play sells 107 tickets and makes a total of $3,375. How many of each type of ticket are sold?
Answer:
floor seats=35
and the balcony seats =72
Step-by-step explanation:
Step one
given data
let the floor seats be x
and the balcony seats be y
so
45x+25y=3375-------1
x+y= 107----------------2
from 2, x= 107-y
put x= 107-y in 1
45(107-y)+25y=3375
4815-45y+25y=3375
collect like terms
-45y+25y= 3375-4815
-20y=-1440
divide both sides by -20
y=72
put y= 72 in eqn 2
x+72=107
x=107-72
x=35

A circle has equation x2 + y2 = 25
The circle passes through the points A, B, C and D.
Complete the coordinates for A, B, C and D.
A. (5,_)
B.(_,-5).
C. (_,0)
D(0,_)
Answer: A. (5; 0), B. (0; - 5), C. (-5; 0), D. (0; 5).
Step-by-step explanation:
A. (5; _) [x = 5; y - ?]
x² + y² = 25
5² + y² = 25
25 + y² = 25
25 + y² - 25 = 25 - 25
y² = 0
y = 0
A. (5; 0)
B. (_; -5) [x - ?; y = -5]
x² + y² = 25
x² + (- 5)² = 25
x² + 25 = 25
x² + 25 = 25
x² + 25 - 25 = 25 - 25
x² = 0
x = 0
B. (0; - 5)
C. (_; 0) [x - ?; y = 0]
x² + y² = 25
x² + 0² = 25
x² + 0 = 25
x² = 25
x = ± √25 = ± 5
C. (-5; 0) or (5; 0)
Point A has coordinates (5; 0), which means that
point C has coordinates (-5; 0).
D. (0; _) [x = 0; y - ?]
x² + y² = 25
0² + y² = 25
0 + y² = 25
y² = 25
y = ± √25 = ± 5
D. (0; - 5) or (0; 5)
Point B has coordinates (0; -5), which means that
point D has coordinates (0; 5).

ILL GIVE U BRAINLIST PLS HELP
Answer:
A. Right a multiple of 2 and up a multiple of 1.
B. (2, 1)
C. the same
Step-by-step explanation:
A. The original point was (2, 1), so if Larissa moves right a multiple of 2 and up a multiple of 1, she'll stay within the ratio.
B. We already know this is proportional, since it goes through the origin; the line just has to pass through the right point: (2,1)
C. The line will be proportional, so as long x is twice as much as y, Larissa will have the same shade of green paint every time.

1) First find the number of buses
Equation:
total students ÷ 60 students per bus = number of buses taken
340 ÷ 60 = 5 buses taken with 40 students left
2) Now find the number of cars taken
Equation:
students left ÷ 5 students per car = number of cars taken
40 ÷ 5 = 8 cars taken with 0 students left
So your answer is 8 cars and 5 buses.
I hope this helps!

After 2 week he has used 8 1/2 cups of dog food after 5 week he has used 21 1/4 cups construct a function in the form y =mx+ to represent the amount of dog food used y, after x weeks
Answer:
y = 4.25x
Step-by-step explanation:
Given that:
After 2 week he has used 8 1/2 cups of dog food after 5 week he has used 21 1/4 cups, we can write this in coordinate form (x, y) where;
y is the amount of dog food
x is the time in weeks
The coordinates are (2, 8 1/2) and (5, 21 1/4)
get the slope m:
m = y2-y1/x2-x1
m = (21 1/4 - 8 1/2)/5-2
m = (85/4-17/2)/3
m = (85-34/4)/3
m = 51/12
m = 4.25
Get the intercept c:
Substitute any of the points say (2, 17/2) and m = 51/12 into the equation
y = mx+c
17/2 = 51/12(2) + c
17/2 = 51/6 + c
c = 17/2 - 51/6
c = 51-51/6
c = 0
Get the required equation:
substitute m - 4.25 and c = 0 into y = mx+c
y = 4.25x + 0
Hence the required equation is y = 4.25x

Find the median of 1.4, 0.9, 2.4, 3.5, 2
Step-by-step explanation:
We arrange the numbers in increasing order:
0.9, 1.4, 2, 2.4, 3.5
Since there are five terms, the median is the third term, which is 2.
The median of the given data set is 2.
What is a median?The median is the middle number in a sorted, ascending or descending list of numbers.
Given is a data set, 1.4, 0.9, 2.4, 3.5, 2, we need to find median,
Rearranging the data from lowest to greatest,
0.9, 1.4, 2, 2.4, 3.5
Since, the median is the middle most value in a data, therefore, the middle most value of the given data is 2.
Therefore, we can say the median is 2.
Hence, the median of the data is 2.

Calculate the length of the thirst side.
Answer:
21
Step-by-step explanation:
Assuming this is a right triangle, we can use Pythagorean Theorem to find the third side. We'll represent the missing side with the variable x.
x² + 20² = 29²
x² + 400 = 841
x² = 441
x = 21
Therefore, the length of the third side is 21.

Which inequalities correctly show the relationship between the numbers 13, −4, and −17?
Answer:
13 > -17 < -4
Step-by-step explanation
13 = postive number
-17 and -4 = negtive.
13 is greater than -17
Since negtive is oppistie of postive it goes backwards.
So -4 is greater than -17

An empty box weighs 200 g the boxes filled with party goody bags and now it weighs 6.2 kg each goodie bag weighs 100 and grams work out how many goody bags are inside the box
Answer:
60 goody bags
Step-by-step explanation:
1 kg = 1000 g
6.2 kg = 6,200 g
Empty box = 200 g
Box + goody bags = 6,200 g
Weight of Goody bags = Box + goody bags - empty box
= 6,200g - 200g
= 6,000 grams
Each goody bag = 100 g
how many goody bags are inside the box
Number of goody bag in the box = total weight of goody bag / weight of each goody bag
= 6,000 grams / 100 grams
= 60 goody bags
There are 60 goody bags in the box
a motorboat moves across a lake at a constant speed. when it begins it from the shore. after 9 minitues it is 14 km from the shore. which function decribes the motorboat distance from the shore?
a. y= 4x + 50
b. y= -4x + 50
c. y= 9x + 50
d. y= -9x + 50
Answer:
Answer:
The function describes the motorboat's distance from the shore
Step-by-step explanation:
A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore
After 9 minutes, it is 14 km from the shore.
So, rate of change =
Negative sign shows that there is decrease in distance per minute
The rate of change of distance is 4 km / minutes
General equation : y = mx+c
Where m is the slope and c is the constant
Substitute the values in the equation :
y=-4x+50
Where y is the final distance and x is the minutes
So, Option C is true
Hence The function describes the motorboat's distance from the shore

how do you differentiate more and more than? can these terms be used in mathematics? how?
Answer:
The terms "more" and "more than" have a clear difference, which is even more noticeable in its application in the field of mathematics.
Thus, "more" has a more general meaning, while "more than" applies specifically to comparing the values of two or more determined variables. Therefore, in the field of mathematics "more than" implies that a variable will have a higher value than another or others, while "more" simply refers to a higher value.

Mean:
Median:
Mode:
Range:
Answer:
mean- 66
median- 7
mode- 8
range- 6
Step-by-step explanation:
to find the mode you line up all the numbers, add them all together and then divide that number by 2.
to find the median you line up all the numbers then one by one taking turns from left to right you cross of the numbers to find the number in the middle. (think of median as middle)
to find mode you just find the number that is used the most. (mode=most)
to find the range you find the highest number and the lowest number. and subtract the lowest from the highest to find the difference between the 2. in this case its 9-3 so the difference is 6.

Max is building a treehouse. He has a piece of wood that is 6 ft long. How many 1/3 ft pieces of wood can you cut
Answer:
18 pieces
Step-by-step explanation:
Max is building a treehouse. He has a piece of wood that is 6 ft long. How many 1/3 ft pieces of wood can you cut?
From the above question, we can deduce that:
1 piece of wood = 1/3ft
Hence:
1/3 = 1 piece of wood
6 ft = x
Cross Multiply
1/3ft × x = 6 ft × 1
x = 6 / 1/3
x = 6 × 3
x = 18 pieces
Hence, you can cut 18 (1/3 ft )pieces of wood .
