Jordan's bathroom floor has been decorated with purple and white tiles.
The ratio of purple tiles to white tiles is (2x + 1): (4x + 13)
If of the tiles are purple, work out the value of x.
Using proportions, supposing that 30% of the tiles are purple, it is found that the value of x is of x = 16.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the ratio of purple tiles to white tiles is given by:
[tex]\frac{2x + 1}{4x + 13}[/tex]
We consider that 30% of the tiles are purple, hence 70% are white, which means that:
[tex]\frac{2x + 1}{4x + 13} = \frac{3}{7}[/tex]
Applying cross multiplication:
14x + 7 = 12x + 39
2x = 32
x = 16.
The value of x is of x = 16.

It takes 27N of work to push a crate up a ramp to a dock. The ramp is 3 meters long. How much force is necessary?
PLEASE HELP
Answer:
Solution:
Given,
Work = 27 N
Displacement = 3 m
According to question,
Force = ?
As we know,
Work = Force × Displacement
or, 27 = Force × 3
or, Force = 27/3
i.e, Force = 9 N
Use the fact that f(x)=sqrt x is increasing on its domain to solve the inequality: sqrt (3x+1) > sqrt (x-5)
Since √(3x+1) and √(x-5) is always positive, you can square out both sides.
[tex] \sqrt{3x + 1} > \sqrt{x - 5} \\ {( \sqrt{3x + 1}) }^{2} > {( \sqrt{x - 5} )}^{2} \\ 3x + 1 > x - 5 \\ 2x > - 6 \\ x > - 3[/tex]
Since substituting x = -2, -1 , ... , 4 into √(3x+1) and √(x-5) will result into complex solutions,
Therefore,
[tex]x > 4[/tex]
Answer:
-3<x≤5
Step-by-step explanation:
√(3x+1)>√(x-5)
Square each one of the square roots. Then create 3 different inequality expressions and solve them/
1. 3x+1>x-5= x>-3
2. 3x+1≥0= x≥-1/3
3. x-5≥0= x≥5
From here I'm going to take the values that cover the most of the area in this expression which should be -3<x≤5.

Enter the measure of ∠TOM, in degrees. (Enter just the number)
Answer: 150
Step-by-step explanation:
We know (5x-15)+(2x)=90 degree
so we can solve x = 15
plug in 5(15) - 15 = 60
60 + 90 = 150
Answer:
150
Step-by-step explanation:
m∠TOG = m∠TOP + m∠POM + m∠MOG
m∠TOG = 180°
m∠TOP = 90°
m∠POM = (5x - 15)°
m∠MOG = (2x)°
90 + ( 5x - 15 ) + 2x = 180 ⇒ 5x - 15 + 2x = 90 ⇒ x = 15
m∠TOM = 90° + m∠POM
m∠TOM = 90° + (5×15 - 15)° = 150 °

show that the derivative of an odd function is even function and viceversal
Step-by-step explanation:
Well, it's hard to generalize this. But I can show you a few examples using the power rule and some derivatives of trig functions. Lets say we have a function:
[tex]f(x) = {x}^{n} [/tex]
Then you should know it's derivative is:
[tex] \frac{df}{dx} = n {x}^{n - 1} [/tex]
For polynomial functions, a subtraction of 1 from the exponent will turn any odd function into an even, and any even function to an odd. An example of this is x^3, which is odd. The derivative is 3x^2, which is even. Another example, this time of a trig function, is sine and cosine. Sine is odd, while cosine is even. The derivative of sine is cosine, and the derivative of cosine is negative sine.

Answer:
46/40, or 1 3/20
Step-by-step explanation:
[tex] \frac{13}{20} + \frac{20}{40} [/tex]
to find:the sum of the two fractions.
solution:first find the LCM of the two denominators and rename the fractions with a common denominator atlast, add and simplify.
