Answer:
5
Step-by-step explanation:
This trick works with 3:
If the sum of the digits of a number is divisble by 3 then the number is divisble by 3.
44 is not divisble by 3 because 4+4=8 is not divisble by 3.
45 is divisble by 3 because 4+5=9 is divisble by 3.
46 is not divisble by 3 because 4+6=10 is not divisble by 3.
47 is not divisble by 3 because 4+7=11 is not divisble by 3.
54 is divisble by 3 because 5+4=9 is divisble by 3.
55 is not divisble by 3 because 5+5=10 is not divisble by 3.
56 is not divisble by 3 because 5+6=11 is not divisble by 3.
57 is divisble by 3 because 5+7=12 is divisble by 3.
64, 65,67 are not divisble by 3 because their digits' sums are 10,11, and 13 respectively. 66 is a winner because 6+6=12 is divisble by 3.
Finally 7...
74,76,77 are not divisble by 3 because their digits' sums are 11,13, and 14 respectively. 75 is divisble by 3 because 7+5=12 is divisble by 3.
The victors are

Answer:
25.7
Step-by-step explanation:
PQ=PR-QR
PQ=38.3-12.6
PQ=25.7 cm
Answer: PQ = 25.7 cm
Concept:
Here, we need to know the idea of the segment addition postulate.
The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Solve:
Given information
PR = 38.3 cm
QR = 12.6 cm
Given expression deducted from the segment addition postulate
PQ = PR - QR
Substitute values into the expression
PQ = (38.3) - (12.6)
Simplify by subtraction
PQ = [tex]\boxed{25.7cm}[/tex]
Hope this helps!! :)

The cube of a whole number is 48 more
than the square of the same number.
What is the number?
Answer:
x = 4
Step-by-step explanation:
Let the number = x
x^3 = x^2 + 48
x^3 - x^2 - 48 = 0
The answer is 4, but I have no method of doing this rigorously. I can just show that it is true.
x^3 = 4^3 = 64
x^2 = 4^2 = 16
64 - 48 = 16

2(2) + 11 = 15
2(3) + 11 = 17
the 2 is the constant difference between the first 2 terms.
the numbers in brackets are the term number.
you have to multiply the difference with the term number.
then you will have to take that answer and subtract it from the first term number.

A plant is already 12.00 meters tall and it will grow 20 cm every month.what is the plants height after 30 months
Answer:
18 m
Step-by-step explanation:
Hi there!
We're given:
⇒ The plant is already 12 m tall
⇒ It grows 20 cm every month
First, we must convert everything into the same unit. Divide 20 cm by 100 to convert it to meters:
20 ÷ 100 = 0.2
Now, we can form this equation:
Plant Height = 12 m + (0.2 m × number of months)
Let plant height be h and number of months be m:
[tex]H=12+0.2m[/tex]
To find the plant's height after 30 months, replace m with 30:
[tex]H=12+0.2(30)\\H=12+6\\H=18[/tex]
Therefore, the plant would be 18 m tall.
I hope this helps!

If (x + 4)^2 = 49 and x < 0. what is the value of x?
Answer:
x = -11
Step-by-step explanation:
To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.
-11 + 4 = -7
(-7)^2 = 49
Answer:
x = -11
Step-by-step explanation:
To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.
