Here, The Right angled triangle is given
So, The sum of angles of right angled triangle is 180
Now,
2x + 42 + 90 = 180
2x + 132 = 180
2x = 180 - 132
2x = 48
x = 48/2
x = 24
FOR VERIFICATION ONLY:2x + 42 + 90 = 180
2(24) + 42 + 90 = 180
48 + 42 + 90 = 180
180 = 180
Hence, L.H.S = R.H.S

what is the y-intercept of 10x + 5y = 30
Answer: 6
Step-by-step explanation: The y-intercept is 6 and the slope is -2.
First, we subtract 10x.
5y = -10x+30
Then we divide by 5.
y = -2x + 6
Now we have everything we need!
So the y-intercept is 6.
Hope this helps! :)
The y-intercept is "6".
Intercept:Given:
[tex]10x+5y=30[/tex]

Write a rational inequality with the solution: (-2,-1)U(1, oo)
Answer:
[tex]\displaystyle \frac{x^2+3x+2}{1-x}<0[/tex]
Step-by-step explanation:
Rational Inequality
We are given the solution of rational inequality:
(-2,-1) U (1,∞)
The first set suggests a limited zone than can be obtained by a quadratic equation of the form:
[tex](x-a)(x-b)<0[/tex]
Where a and b are the roots of the equation, which coincide with the endpoints of the interval. Thus, to get the interval, we can use:
[tex](x+2)(x+1)<0[/tex]
Operating:
[tex]x^2+3x+2<0[/tex]
The second set is an open infinite interval, that can be modeled as a third binomial that changes signs in x=1 and is in the denominator, so x=1 is not included.
Thus, one possible inequality is:
[tex]\mathbf{\displaystyle \frac{x^2+3x+2}{1-x}<0}[/tex]
The solution to the inequality (-2,-1)U(1, ∞) is (-2, ∞)
Inequality
An inequality is an expression used to show the relationship between two or more numbers and variables.
A rational inequality is an inequality that contains a rational expression.
Given the inequality (-2,-1)U(1, ∞).
The solution to the inequality is (-2, ∞)

A study involves a population of 400 tall women. This population has a mean height of 179.832 cm and a standard deviation of 12.192 cm. If 50 of these women are randomly selected, find the probability that the mean for this sample group is above 182.88
Answer: 0.0386
Step-by-step explanation:
Given: The population of 400 tall women has a mean height[tex](\mu)[/tex] of 179.832 cm and a standard deviation[tex](\sigma)[/tex] of 12.192 cm.
Let X be a random variable that represents the height of woman.
Sample size : n= 50
The probability that the mean for this sample group is above 182.88 will be :
[tex]P(\overline{X}>182.88)\\\\=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{182.88-179.832}{\dfrac{12.192}{\sqrt{50}}})\\\\ =P(Z>1.7678)\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-P(Z<1.7678)\\\\=1-0.9614\ \ \ [\text{By p-value table}]\\\\= 0.0386[/tex]

Elwin is attempting to read a 480 page book in 28 days. He reads the first 60 pages in 4 days. At this rate, will he finish the book in time? Show your work and/or explain your reasoning.
Answer:
No, he won't
Step-by-step explanation:
Given
Target = 480 pages in 28 days
Rate = 60 pages in 4 days
Required:
Determine if he'll reach his target
The rate can be expressed using:
[tex]Rate = \frac{Pages}{Days}[/tex]
So, we have:
[tex]Rate = \frac{60\ pages}{4\ days}[/tex]
Multiply the fraction by [tex]\frac{7}{7}[/tex]
[tex]Rate = \frac{60\ pages}{4\ days} * \frac{7}{7}[/tex]
[tex]Rate = \frac{60\ pages * 7}{4\ days * 7}[/tex]
[tex]Rate = \frac{420\ pages}{28\ days}[/tex]
This can be interpreted as: 420 pages in 28 days
And his target is 480 pages in 28 days
Hence, he wont finish the book at that rate

There were 30 boys in Orchestra.
We have,
Total students in Orchestra= 75
Ratio of Girls to Boys = 3 :2
So, Number of Girls in Orchestra
= 3/5 x 75
= 3 x 15
= 45
and, Number of Boys in Orchestra
= 2/5 x 75
= 2 x 15

Bill buys a new machine.
The value of the machine depreciates by 20% each year.
Bill wants to work out the value of the machine after 2 years.
By what single decimal number should Bill multiply the value of the machine when new?
Answer:
For a, the machine depreciates 20% of its current value each year. So, It will lose 20% of its value in the first year. Then in the second year, it will lose 20% of THAT value (not of the original value) and so on.
b) Since the machine loses 20% of its value each year, it retains 80% of its value each
find the slope of a line parallel to each given line y = x + 2
Answer:
y = x + 4
Step-by-step explanation:
For a line to be Parallel it has to have the same slope but different y intercept
Answer:
1
Step-by-step explanation:
This equation is written in the
y = mx + b,
where "m" is the slope, and "b" is the y-intercept.
In this case, m=1, hence the "x" has no coefficient; therefore, the slope of the given line is 1.
When 2 lines are parallel, they run next to each other, for infinitely long, yet they never touch. This means that 2 parallel lines have the same slope. Hence a line running parallel to the given one will also have a slope of 1.
