How many number less than 300 is exactly divisible by 8, 12, 18?
Count how many multiples of 8, 12, or 18 there are in the range {1, 2, 3, …, 300}:
⌊300/8⌋ = 37
⌊300/12⌋ = 25
⌊300/18⌋ = 16
(where ⌊n⌋ denotes the floor of n, i.e. the largest integer that is smaller than n; for instance, 300/8 = 37.5, so ⌊300/8⌋ = ⌊37.5⌋ = 37)
Take pairwise LCMs, as well as the LCM of all three numbers:
LCM(8, 12) = LCM(2³, 2²×3) = 2³×3 = 24
LCM(8, 18) = LCM(2³, 2×3²) = 2³×3² = 72
LCM(12, 18) = LCM(2²×3, 2×3²) = 2²×3² = 36
LCM(8, 12, 18) = LCM(2³, 2²×3, 2×3²) = 2³×3² = 72
Count how many multiples there are of each of these LCMs that are less than 300:
⌊300/24⌋ = 12
⌊300/72⌋ = 4
⌊300/36⌋ = 8
Then, using the inclusion/exclusion principle, the number of numbers less than 300 that are exactly divisible by 8, 12, or 18 is
{multiples of 8} + {multiples of 12} + {multiples of 18}
- {multiples of 24} - {multiples of 72} - {multiples of 36}
+ {multiples of 72}
= 37 + 25 + 16 - 12 - 4 - 8 + 4 = 58

55. (a) If alpha and beta are the roots of the equation xsquare+ px+q=0 and beta>alpha find the square of the
difference of the roots in terms of p and q.
Answer:
√(p²-4q)
Step-by-step explanation:
Using the Quadratic Formula, we can say that
x = ( -p ± √(p²-4(1)(q))) / 2(1) with the 1 representing the coefficient of x². Simplifying, we get
x = ( -p ± √(p²-4q)) / 2
The roots of the function are therefore at
x = ( -p + √(p²-4q)) / 2 and x = ( -p - √(p²-4q)) / 2. The difference of the roots is thus
( -p + √(p²-4q)) / 2 - ( ( -p - √(p²-4q)) / 2)
= 0 + 2 √(p²-4q)/2
= √(p²-4q)

The ratio of Mitchell's age to Connor's age is 8:5. In thirty years, the ratio of their ages will be 6:5. How much older is Mitchell than Connor now?
Answer:
9 years older
Step-by-step explanation:
The ratio of their ages is 8 : 5 = 8x : 5x ( x is a multiplier )
In 30 years their ages will be 8x + 30 and 5x + 30 and the ratio 6 : 5 , so
[tex]\frac{8x+30}{5x+30}[/tex] = [tex]\frac{6}{5}[/tex] ( cross- multiply )
5(8x + 30) = 6(5x + 30) ← distribute parenthesis on both sides
40x + 150 = 30x + 180 ( subtract 30x from both sides )
10x + 150 = 180 ( subtract 150 from both sides )
10x = 30 ( divide both sides by 10 )
x = 3
Then
Michell is 8x = 8 × 3 = 24 years old
Connor is 5x = 5 × 3 = 15 years old
Mitchell is 24 - 15 = 9 years older than Connor

Geometry, please answer question ASAP
Answer:
66
Step-by-step explanation:
since BD and BC are congruent, angle C and angle D are equal. this means 6x-9=3x+24. If you solve this equation you get x=11. If you plug it into either 6x-9 or 3x+24 you get 57. 180-(57+57)=66

Is (7,0) a solution to the equation y = x - 2?
Answer:
no
Step-by-step explanation:
because 7-7=0 and it doesn't subtract by 2
it is not equal to y=x-2
Answer:
no
Step-by-step explanation:
y = x-2
Let x = 7 and y=0
0 = 7-2
0 =5
This is not a true statement so (7,0) is not a solution

all sets to which the number 3/2 belongs.
1 rational numbers, real numbers
2 integers, rational numbers, real numbers
3 irrational numbers, real numbers
4 natural numbers, whole numbers, real numbers
Answer:
1
Step-by-step explanation:
as a fraction it is per definition a rational number.
and the real numbers are a superset of radical numbers.
but 3/2 is not a natural, integer or whole number, as they can all be written as numbers without digits after the decimal point.
and it is a a rational number not irrational, as that would be all numbers with digits after the decimal point, that cannot be expressed as fractions.

A rectangular hockey field is 50m long and 35m wide calculate the length of it's diagonal
Answer:
length=50m
width=35m
diagonal=?
using Pythagoras theorem
where c=diagonal,a=length(50m),b=width(35)
c² =a² + b²
c² =(50)² + (35)²
c² =2500+1225=3725
Taking square root on both sides
c=61m
Therefore the diagonal is 61m

Answer:
IU=161
Step-by-step explanation:
Angle Formed by Two Secants= 1/2 (difference of Intercepted Arcs)
42 = 1/2 (7m+5 - (3m-1))
Distribute the minus sign
42 = 1/2 (7m+5 - 3m+1))
Combine like terms
42 = 1/2 ( 4m+6)
Distribute the 1/2
42 = 2m+3
Subtract 3 from each side
42-3 = 2m+3-3
39 = 2m
Divide by 2
19.5 = m
The sum of the arcs = 360
IU+ 3m-1 + 7m+5 = 360
IU +10m+4 = 360
IU +10(19.5) +4 = 360
IU +195+4 = 360
IU = 360 - 199
IU=161

What is the probability of a red on this spinner?
Be sure to reduce.
Answer:
2/8 or 1/4 simplified
Step-by-step explanation:
If you count how many equal sections there are, you will see there are 8, and 2 or those 8 sections are red so that would easily give you your answer, 2/8.
And to simplify it divide both the top and the bottom by 2 and that gives you 1/4.
Hope the helps! :)
The probability of a red on this spinner would be 1/4.
Used the concept of probability that states,
The term probability refers to the likelihood of an event occurring. Probability means possibility.
Given that,
A spinner is shown in the image.
Since there are a total of 8 parts with different colors.
And, the number of red colors on this spinner is 2.
Hence, the probability of a red on this spinner would be,
P = 2 / 8
P = 1 / 4
Therefore, the probability is 1/4.

Topic: Simultaneous equations
Class 9 ICSE
Answer:
19 and 13
Step-by-step explanation:
Let x be the larger number and y the smaller , then
[tex]\frac{3x}{y}[/tex] = 4 + [tex]\frac{5}{y}[/tex] ( multiply through by y to clear the fractions )
3x = 4y + 5 ( subtract 4y from both sides )
3x - 4y = 5 → (1)
and
[tex]\frac{6y}{x}[/tex] = 4 + [tex]\frac{2}{x}[/tex] ( multiply through by x to clear the fractions )
6y = 4x + 2 ( subtract 4x from both sides )
- 4x + 6y = 2 → (2)
Multiplying (1) by 4 and (2) by 3 and adding will eliminate x
12x - 16y = 20 → (3)
- 12x + 18y = 6 → (4)
Add (3) and (4) term by term to eliminate x
0 + 2y = 26
2y = 26 ( divide both sides by 2 )
y = 13
Substitute y = 13 into (1) and solve for x
3x - 4(13) = 5
3x - 52 = 5 ( add 52 to both sides )
3x = 57 ( divide both sides by 3 )
x = 19
The 2 numbers are 19 and 13

If LM = 9x + 27 and RS = 135, find x.
Answer:
x=12
Step-by-step explanation:
LM = RS
9x+27 = 135
Subtract 27 from each side
9x+27-27 =135-27
9x=108
Divide each side by 9
9x/9 = 108/9
x = 12
the boxes are equivalent so the one with a single dash is equal to the other with a single dash.
the one with 2 dashes is equal to the other with 2 dashes so on and so forth
SR=LM
LM=9x+27
RS=135
9x+27=135
so I solve it in my own weird way but you can solve it differently. 135-27=108
108/9=12
so your answer is 12

[tex]75\%[/tex]
Step-by-step explanation:
[tex] \frac{3}{4} \times 100\%[/tex]
100 is divided by 4, so you will get 25.
25 multiply 3, you will get 75%
So, the answer is 75%.
Answer:
Step-by-step explanation:
I'm not sure what you're asking for but I'll assume you mean what percentage is the three so:
There are 7 total parts bc 3 + 4 = 7.
3/7 is 42.857142857% repeating decimal
If you mean 3/4 then it's 75% bc 3/4 is 0.75
