Or relation I believe so...
Answer:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Equal quotients correspond to equal ratios.

Factorise 3x^2+13x+4 by splitting the middle term
Answer:
( x + 4 ) ( 3x + 1 )
Step-by-step explanation:
→ Identify the product, sum & factors
Product = 4
Sum = 13
Factors = 4 & 1
3x² + 12x + x + 4
→ Factorise 3x² + 12x and x + 4
3x² + 12x ⇔ 3x ( x + 4 )
x + 4 ⇔ 1 ( x + 4 )
→ Take out the ( x + 4 ) as a factor and ( 3x + 1 )
( x + 4 ) ( 3x + 1 )
1.) The island shown has a population of 12,175 people. Find the population
density in people per square kilometer.
18.5 km
11.1 km
Answer:
Population density = [tex]148.22\ \text{people per square kilometer}[/tex]
Step-by-step explanation:
The attached figure shows the dimension of an island.
Population density is equal to total population per unit land area.
Firstly we will find the area of the triangle using Pythagoras theorem as follows :
[tex]H^2=B^2+P^2[/tex]
H is Hypotenuse, B is base and P is perpendicular
[tex]B=\sqrt{H^2-P^2} \\\\B=\sqrt{(18.5)^2-(11.1)^2} \\\\B=14.8\ km[/tex]
Area of triangle is given by :
[tex]A=\dfrac{1}{2}\times b\times P\\\\A=\dfrac{1}{2}\times 14.8\times 11.1\\\\A=82.14\ km^2[/tex]
[tex]\text{Population density}=\dfrac{\text{Total population}}{\text{land area}}\\\\=\dfrac{12175 }{82.14}\\\\=148.22\ \text{people per square kilometer}[/tex]
Hence, the population density is [tex]148.22\ \text{people per square kilometer}[/tex].
The weight of an object rounds to 41.3 kilograms select the three posible weights that correctly round to 41.3 kilograms
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Weight = 41.3kg[/tex]
Required
Determine the weights that approximates to 41.3kg
The options are not given but the question is still solvable
In approximation:
0 - 4 approximates to 0
This implies that:
41.30 to 41.34 approximates to 41.3
Also:
5 - 9 approximates to 1
This implies that:
41.25 to 41.29 approximates to 41.3
Bring the range together, we have:
[tex]Range = 41.25\ to\ 41.34[/tex]
Select any three numbers within this range, and you have your answer
Examples are: 41.25, 41.28, 41.34\

a fish tank at an aquarium has a volume of 1568 cubic feet and a depth of 8 feet. if the base of the tank is square, what is the length of each side of the tank?
Answer:
14 feet.
Step-by-step explanation:
Volume=base area×height
1568=(L×L)×8
1568=8L²
Divide both sides by 8
L²=196
Then square root each side
L=14 feet

3 l4w-1l -5 = 1
Answer:
w = 3/4 or w = -1/4
Step-by-step explanation:
3l4w - 1l - 5 = 1
Add 5 to both sides.
3|4w - 1| = 6
Divide both sides by 3.
|4w - 1| = 2
Set the inside of the absolute value equal to 2 and -2.
4w - 1 = 2 or 4w - 1 = -2
Add 1 to both sides.
4w = 3 or 4w = -1
Divide both sides by 4.
w = 3/4 or w = -1/4
Check w = 3/4:
3l4w - 1l - 5 = 1
3|4(3/4) - 1| - 5 = 1
3|3 - 1| - 5 = 1
3|2| - 5 = 1
6 - 5 = 1
1 = 1
w = 3/4 works.
Check w = -1/4:
3l4w - 1l - 5 = 1
3|4(-1/4) - 1| - 5 = 1
3|-1 - 1| - 5 = 1
3|-2| - 5 = 1
3(2) - 5 = 1
6 - 5 = 1
1 = 1
w = -1/4 works.
There are no extraneous solutions.
Answer: w = 3/4 or w = -1/4

765ab4 is divisible by 36. Compute all ordered pairs (a, b) for which this is possible
Answer:
All the ordered pairs (a,b) are
(0,5), (2,3), (4,1), (6,8), and (8,6).
Step-by-step explanation:
765ab4 to be divisible by 36, it must be divisible by both 9 and 4.
For any number to be divisible by 4, the last two digits of the number must be divisible by 4.
Here, the last two digits are b4, so as the number b4 is divisible by 4, b can be 0,2,4,6, and 8.
For any number to be divisible by 9, the sum of all the digit of the number must be divisible by 9.
Here, the sum of all the digits, S= 7+6+5+a+b+4=22+a+b.
Now, we have b={0,2,4,6, 8}
For b=0,
S=22+a+0=22+a which is a multiple of 9.
So, the possible value of the digit a :
a=5
So, (a,b)=(0,5)
For b=2,
S=22+a+2=24+a which is a multiple of 9.
So, the possible value of the digit a :
a=3
So, (a,b)=(2,3)
For b=4,
S=22+a+4=26+a which is a multiple of 9.
So, the possible value of the digit a :
a=1
So, (a,b)=(4,1)
For b=6,
S=22+a+6=28+a which is a multiple of 9.
So, the possible value of the digit a :
a=8
So, (a,b)=(6,8)
For b=8,
S=22+a+8=30+a which is a multiple of 9.
So, the possible value of the digit a :
a=6
So, (a,b)=(8,6)
Hence, all the ordered pairs (a,b) are
(0,5), (2,3), (4,1), (6,8), and (8,6).

What is Cosine function?cosine function formula in terms of sides of a right-angled triangle is written as:
cos x = Adjacent Side/Hypotenuse = Base/Hypotenuse, where x is the acute angle between the base and the hypotenuse.
Properties of Cosine FunctionProperties of cosine depend upon the quadrant in which the angle lies. The cosine function is a special trigonometric function and has many properties. Some of them are listed below:
The cos x graph repeats itself after 2π, which suggests the function is periodic with a period of 2π.Cos x is an even function because cos(−x) = cos x.The domain of cosine function is all real numbers and the range is [-1,1].The reciprocal of the cosine function is the secant function.As, The graphs of sine and cosine have the same shape: a repeating “hill and valley” pattern over an interval on the horizontal axis that has a length of .
Hence, the graph is symmetric about the y-axis.

Find the equation of the line passing through the point (4,−1) that is parallel to the line 2x−3y=9
Answer:
[tex]y = \frac{2}{3} x - 3 \frac{2}{3} [/tex]
Step-by-step explanation:
Let's rewrite the given equation in the form of y= mx +c, where m is the gradient while c is the y-intercept.
2x -3y= 9
3y= 2x -9
Divide by 3 throughout:
[tex]y = \frac{2}{3} x - 3[/tex]
Thus, the gradient of given line is ⅔.
Parallel lines have the same gradient.
Therefore, gradient of line is ⅔.
Substitute m=⅔ into the equation:
[tex]y = \frac{2}{3} x + c[/tex]
To find the value of c, substitute a pair of coordinates.
When x=4, y= -1,
[tex] - 1= \frac{2}{3} (4) + c \\ - 1 = \frac{8}{3} + c \\ c = - 1 - \frac{8}{3} \\ c = - 3 \frac{2}{3} [/tex]
Substitute the value of c:
[tex]y = \frac{2}{ 3} x - 3 \frac{2}{3} [/tex]
