Chord AC intersects chord BD at point P in circle Z. AP=12 m DP=5 m PC=6 m What is BP?
Answer:
BP = 14.4
Step-by-step explanation:
Given 2 chords intersecting inside a circle, then
The products of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is
BP × DP = AP × PC , that is
BP × 5 = 12 × 6
5BP = 72 ( divide both sides by 5 )
BP = 14.4

PLEASEE HELP ILL GIVE BRAINLIEST
Answer: 2025
Step-by-step explanation: first you multiply 30x15x9= 4050 but you keep going and then divide 4050/2= 2025 and that would be your answer
A=2025
The volume of the right triangular prism in cubic fee should be considered as the 2025.
Calculation of the volume of the right triangular prism:here first we have to multiply the 30, 15 and 9 with each other so it comes 4050
Now we have to half the 4050 so it comes 2025
hence, The volume of the right triangular prism in cubic fee should be considered as the 2025.

A total of 150 tickets were sold for the annual concert. Student tickets were $4 and non-students $8. If the total revenue was $840, how many tickets of each type were sold ?
Answer:
x = 90
y = 60
Step-by-step explanation:
Let x = student
Let y = non-student
x + y = 150
4x + 8y = 840 <—— Use elimination/addition ethos for both equations
8 (x + y = 150)
-1 (4x + 8y = 840) <—— Let’s eliminate y
8x + 8y = 1200
+ -4x - 8y = -840
—————————————
4x = 360
x = 90
x + y = 150 <— substitute for x from above
90 + y = 150
- 90 = - 90 <— subtract from both sides
y = 60

Answer:
Step-by-step explanation:
Noma cleans 12 pools in 8 hours
How many pools in how many minutes?
8 x 60= 480
He cleans 12 pools in 480 minutes
How many minutes does he take to clean a pool?
480/12 = 40
He cleans a pool in 40 minutes.
How much does he earn to clean a pool?
since he cleans 12 pools to earns $270
then 270/12 =22.5
Therefore, he charges $22.5 to clean a pool in 40 minutes.
Albert 9 pools in 7.5 hours
How many pools in how many minutes?
7.5 x 60= 450
He cleans 9 pools in 450 minutes
How many minutes does he take to clean a pool?
450/9 = 50
He cleans a pool in 50 minutes.
How much does he earn to clean a pool?
since he cleans 9 pools to earns $195.75
then 195.75/9 =21.75
Therefore, he charges $21.75 to clean a pool in 50 minutes.

The number that when you multiply it by 0.9 and subtract 6.3 from the product, you get 4.5 is 12.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let the number be x.
According to the problem, we have:
0.9x - 6.3 = 4.5
Adding 6.3 to both sides, we get:
0.9x = 10.8
Dividing both sides by 0.9, we get:
x = 12
