Answer: x = 23, y = 40
Step-by-step explanation:
By the same-side interior angles theorem, y+30 and 110 are supplementary.
110 + y + 30 = 180 [supplementary angles add to 180 degrees]y + 140 = 180 [combine like terms]y = 40 [subtract 140 from both sides]We know that the 3x + 1 angle and y + 30 are also congruent, so:
3x + 1 = y + 30 [congruent angles have equal measure]3x + 1 = 40 + 30 [substitute y = 40]3x + 1 = 70 [combine like terms]3x = 69 [subtract 1 from both sides]x = 23 [divide both sides by 3]Related Questions
if a tap leaks at the rate of 1 L per half minute, how many litres are Lost after 10 minutes?
Answers
Answer:
The answer is 20 L
Step-by-step explanation:
if 1/2 minutes = 1 L
10 minutes = 20 L
Answer:
20 liters
Step-by-step explanation:
when working with math problems about the rate that something is happening, it is typically helpful to find the unit rate.
In this case, the unit rate will be how many liters are lost in 1 minute (per unit essentially means per "1" )
we know that 1 liter is lost in 1/2 minute
1/2 minute = 1 liter
×2 ×2 {multiply both sides by 2 to find "1 minute"}
1 minute = 2 liters
So, for every 1 minute, we lose 2 liters
if we have 10 minutes, we can multiply both sides by 10:
1 minute = 2 liters
×10 ×10
10 minutes = 20 liters
So, after 10 minutes, 20 liters are lost

Answers
Step-by-step explanation:
each term in the sequence is half of the value of the previous term, and in the opposite sign.
therfore, the quotient between terms is (-2)
so, to get one term from the previous term, we multiply by 1/(-2), so:
d(n) = d(n-1) × 1/(-2)

find the binomial expansion of (2+3x)^5 - (2 - 3x)^5
Answers
The binomial expansion of (2+3x)^5 - (2 - 3x)^5 is 480x + 2160x^3 + 486x^5
Concept: Binomial expansion is to expand and write the terms which are equal to the natural number exponent of the sum or difference of two terms.
For two terms x and y the binomial expansion to the power of n is (x + y)n = nC0 0 xn y0 + nC1 1 xn - 1 y1 + nC2 2 xn-2 y2 + nC3.
Binomial expansion of (2+3x)^5 =32+240x+720x^2+1080x^3+810x^4+243x^5
Binomial expansion of (2-3x)^5 = 32-240x+720x^2-1080x^3+810x^4-243x^5
Combining both the expansions,=32+240x+720x^2+1080x^3+810x^4+243x^5 - (32-240x+720x^2-1080x^3+810x^4-243x^5)
= 32+240x+720x^2+1080x^3+810x^4+243x^5 - 32+ 240x - 720x^2 +1080x^3 -810x^4 +243x^5

A 2-variable linear programming problem is nicely solved by graphing. The solution will be one of the vertices of the solution set. The attached graph shows that means it is one of (x, y) = [(0, 0), (0, 6), (4, 4), (6, 2), (7, 0)}.
__
Evaluating the objective function at each of these vertices will show you the solution that maximizes it.
(0, 0) -- P = 40·0 +50·0 = 0
(0, 6) -- P = 40·0 +50·6 = 300
(4, 4) -- P = 40·4 +50·4 = 360
(6, 2) -- P = 40·6 +50·2 = 340
(7, 0) -- P = 40·7 +50·0 = 280
_____
Additional comment
The solution set would ordinarily be the area that is covered by the shading that signifies the solution set of each of the 5 inequalities. 5 different overlapping shadings can make the graph quite messy, so we have elected to shade the areas that are NOT part of the solution set. In doing so, we have made the boundary lines dashed when they are part of the solution set
The possible solutions are the vertices of the white space on the graph.
The black line on the graph is the line corresponding to the maximum value of the objective function. To maximize the objective function, we want that line as far from the origin as possible. It is shown intersecting the vertex of the solution space that meets that condition.

In one month, a farmer produces 300 pounds of corn. In the
following month he produces 35% more. How many pounds of corn
does he produce in the second month?
Answers
The pounds of corn in the second month is 390
How to determine the amount?We have:
First month, a = 300
Rate, r = 35%
The pounds of corn in the second month is calculated using:
Pound = a * (1 + r)
So, we have:
Pound = 300 * (1 + 30%)
Evaluate the sum
Pound = 300 * 1.3
Evaluate the product
Pound = 390
Hence, the pounds of corn in the second month is 390

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Now, First, find the area of the two squares:
The photograph have vertices:
(-3, -2), (-2, 2), (2, 1), and (1, -3).
Since, The square is diagonally aligned, so we need to find the length between two points in order to find the area.
For (1, -3) and (2, 1).
There is a 1 unit length and a 4 unit height.
We can use the Pythagorean theorem to find the hypotenuse of the triangle, which is the length of the square's side:
1² + 4² = x²
1 + 16 = x²
x = √17
The side length for the square of the photograph is the square root of 17,
so the area of the photograph is 17 units²
Now, The red paper has side lengths of 8. The distance between (-4, 4) and (4, 4) is 8 units wide, so we do not need to use the Pythagorean theorem.
Now , we know the area of the red paper and photograph, you can subtract the area to find the red paper with the hole:
64 - 17 = 47 square units.
Thus, The area of the piece of red paper after the hole for the photograph has been cut is,
⇒ 47 square units.

About 10% of the population has a particular genetic mutation. 1000 people are randomly selected.
Find the mean for the number of people with the genetic mutation in such groups of 1000. Round your answer to two decimal places.
Answers
Answer:
The standard deviation for the number of people with the genetic mutation in such groups of 1000 is 9.49.
Step-by-step explanation:
Standard deviation: It is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.
The given parameters are:
Proportion, p = 10%
Sample size, n = 1000
The standard deviation is calculated as:
σ=[tex]\sqrt{np(1-p}[/tex]
So, we have:
σ=[tex]\sqrt{1000*10%*(1-10%)}[/tex]*(1-10%)
Evaluate:
σ= 9.49

Answers
Answer:
By using opposite angles of two intersecting straight lines are congruent we proved that x = 28°
Step-by-step explanation:
Opposite angles of two intersecting straight lines are congruent
Therefore ∠DLE = ∠GLH
Here ∠DLE = 2x = ∠GLH
Sum of all angles on a straight line is 180°
Therefore ∠ELG + ∠GLH = 180°
Given that ∠ELG = 124°
124° + ∠GLH = 180°
124° + 2x = 180°
2x = 180° - 124°
2x = 56°
x = 28°
hence proved that x = 28°
