P'(-2,5) is the image of P after a dilation centered at the origin with a
scale factor of 1/3. What are the coordinates of P?
Explanation:
When going from the preimage P to its image P', we multiply each coordinate by the scale factor 1/3.
To go in reverse (image to preimage), we multiply by the reciprocal of that scale factor. The reciprocal of 1/3 is 3/1 or simply 3.
Triple the coordinates of (-2, 5) to end up with (-6, 15)
We can check the answer by multiplying each coordinate of (-6, 15) by the original scale factor 1/3 and you should end up with (-2, 5) again.

Ralph painted 1/6 of a wall in 2/3 hour. At this rate how many hours will it take Ralph to paint the whole wall?
Answer:
4 hours
Step-by-step explanation:
1/6 is one segment
6 segments make a whole
6/6 = 1
2/3 is equal to one segment
2/3 * 6 = 4
Answer:
It will take 4 hours.
Step-by-step explanation:
Let the size of whole wall be x.
Given that
Ralph painted 1/6 of a wall in 2/3 hours
thus, writing it in mathematical form we have,
time taken to pain 1/6 of x = 2/3 hours
=time taken to pain x/6 wall = 2/3 hours
since, we have taken size as x so to find time to pain x size of wall ,
we divide both side by 6
=time taken to pain x/6 * 6 wall = 2/3 *6 hours
= time taken to paint x wall = 4 hours

What is Radical?The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.
An expression that uses a root, such as a square root, cube root is known as a radical notation.
Given:
2√5 x 5√5
So, Multiplying the roots
= 2√5 x 5√5
= ( 2x 5) ( √5 x √5)
= 10 x 5
= 50
hence, the multiplication of Radical gives 50.

Last year Jonathan was 60 3/4 inches tall. This year he is 65 1/4 inches tall. How many inches did he grow?
Answer:4 1 /2
Step-by-step explanation:
A. V(t)=0.87(22,000)^t
B. V(t)=1.13(22,000)^t
C. V(t)=22,000(0.87)^t
D. V(t)=22,000(1.13)^t
Answer:
C.
Step-by-step explanation:
A and B you can already eliminate because you need to power the rate not the starting value. D is wrong because it's increasing, so if the value increased by 0.13 each year it would be right. So you're left with C
Find two consecutive positive even integers such that the square of the first decreased by 64 equals 3 times the second.
Answer:
10 and 12
Step-by-step explanation:
let the consecutive even integers be n and n + 2 , then
n² - 64 = 3(n + 2) ← distribute parenthesis
n² - 64 = 3n + 6 ( subtract 3n + 6 from both sides )
n² - 3n - 70 = 0 ← in standard form
(n - 10)(n + 7) = 0 ← in factored form
Equate each factor to zero and solve for n
n - 10 = 0 ⇒ n = 10
n + 7 = 0 ⇒ n = - 7
Since n must be a positive even integer then n = 10 and n + 2 = 10 + 2 = 12
The 2 numbers are 10 and 12

The difference between twice one number and a lesser number is 32. The sum of the lesser number and twice the greater is 60. Find the numbers
Answer:
The numbers are 23 , 14
Step-by-step explanation:
Let the greater number = x
The smaller number = y
2x - y = 32 ------------(I)
2x + y = 60 ----------------(II)
Add the two equations. Thus y will be eliminated and we can find the value of x
(I) 2x - y = 32
(II) 2x + y = 60 {Now, add}
4x = 92
x = 92/4
x = 23
Plugin x = 23 in equation (II)
2*23 + y = 60
46 + y = 60
y = 60 - 46
y = 14
The numbers are 23 , 14
