A school allots £2000 to spend on a trip to the theatre. Theatre tickets have a regular cost of £32 each and are on offer for 1 4 off. A train ticket for the day will cost £12 each. If 2 teachers and the maximum number of students attend, how much money will the school have left over?
Answer:
£20
Step-by-step explanation:
Given that:
Total amount alloted = 2000
Ticket cost = 32
Discount = 1/4 off
Hence, ticket price = 3/4 * 32 = 24
Train ticket cost = 12
Total cost per person = £(12 + 24) = £36
Hence, alloted amount / cost per person
= £2000 / £36
= 55.55
Total number that can attend = 2 teachers and 53 students
Change = £2000 - (£36*55)
= £20
help find missing segment??
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Let x as the missing segment.
_________________________________
According to the Thales theorem :
[tex] \frac{26}{x} = \frac{12}{36} \\ [/tex]
[tex] \frac{26}{x} = \frac{12}{12 \times 3} \\ [/tex]
[tex] \frac{26}{x} = \frac{1}{3} \\ [/tex]
Inverse both sides
[tex] \frac{x}{26} = \frac{3}{1} \\ [/tex]
[tex] \frac{x}{26} = 3 \\ [/tex]
Multiply sides by 26
[tex]26 \times \frac{x}{26} = 26 \times 3 \\ [/tex]
[tex]x = 26 \times 3[/tex]
[tex]x = 78[/tex]
Thus the missing segment has a measure of 78 .

Write the equation for the line that is parallel to the given line and that contains
the given point. Use the point-slope form of the equation of a line.*
(-3,4) y=-x-11
Answer:
x + y - 1 = 0
Step-by-step explanation:
y = -x - 11
therefore its slope is -1
x1= -3
y1 = 4
m = -1
from, y - y1 = m(x -x1)
y - 4 = -1(x + 3)
y -4 = -x -3
x + y -1 = 0

12x-9=10x-15 Help me answer this please
Answer:
x = -3
Step-by-step explanation:
Given:
12x - 9 = 10x - 15
Now, let's add 15 to both sides of the equation.
12x + 6 = 10x
Now, let's subtract 12x from both sides of the equation.
6 = -2x
Now, let's divide both sides by -2.
-3 = x
A plant is already 43 centimeters tall, it will grow one centimeter every month. The plants height H (in centimeters) , after m month is given by the following. H=43+m , What is the height after 31 months?
Answer:
H=74 cm
Step-by-step explanation:
it grows 1 cm every month, so after 31 months, it will have grown 31 more cm.
add the 31 cm to the 43 cm it was before, and you get 74 cm
Answer:
H = 74
Step-by-step explanation:
H = 43 + m
m = 31 × 1
= 31
H = 43 + 31
H = 74

Answer:
∠ B ≈ 62.73°
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{8}{9}[/tex] , thus
∠ B = [tex]sin^{-1}[/tex] ([tex]\frac{8}{9}[/tex] ) ≈ 62.73° ( to the nearest hundredth )
