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.

Step-by-step explanation:
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 °

Please answer!!!!! What is the probability that the dart will NOT land in the shades region?
help pls i'm not good at math
Answer: x = 56
Step-by-step explanation:
The two angles 'z' and 124 add up to form a straight line. The angle of a straight line is 180 degrees. Therefore, we can say that:
[tex]z+124=180[/tex]
Subtract 124 on both sides to isolate the angle 'z' to get:
[tex]z=56[/tex]
Answer:
z=56 degrees
Step-by-step explanation:
in total the line will equal 180 so just do 180-124 and you get 56.

Your answer:
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.

pidWhat is the sum of 13/20 and 20/40?
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.
[tex] \frac{(13 \times 40) + (20 \times 20)}{20 \times 40} [/tex]
[tex] = \frac{520 + 400}{800} [/tex]
[tex] = \frac{920}{800} [/tex]
Reduce by dividing both the numerator and denominator by the Greatest Common Factor which is 40.
[tex] \frac{920 \div 40}{800 \div 40} = \frac{23}{20} [/tex]
[tex] = 1 \frac{3}{20} [/tex]
