Answer:
72
Step-by-step explanation:
The answer is 72 because it is a simliar triangle, all the sides are proportional to each other. 45/5=9, 63/7=9, so the factor is 9. 9 times 8 is 72.
Question- Solve for a
2a+b=x
Answer:
a = (x - b)/2
Step-by-step explanation:
2a + b = x
-b -b
2a = x - b
/2 /2
a = (x - b)/2
for ex:
x = 3
b = 2
a = ((3) - (2))/2 = 0.5
a = 0.5
2a + b = x
2(0.5) + 2 = 3
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

Help please it says round your answer to the nearest hundredth
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 )

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

Find the slope when given the following points.
(2, 1) and (5, 3)
Answer:
2/3
Step-by-step explanation:
We can find the slope using
m = ( y2-y1)/(x2-x1)
= ( 3-1)/(5-2)
= 2/3
Answer:
2/3
Step-by-step explanation:
Use the equation y2-y1/x2-x1
So, 3-1/5-2

What is the relationship between segments?
Answer:
When you have intersecting segments such as these, the relationship is that the product of the segment pieces of one segment is equal to the product of the segment pieces of the other. You can use this relationship to help you solve problems that ask you find the length of a missing segment piece.

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
