Answer:
3x+2 + 6x+7 + 90 = 180
x=9
Step-by-step explanation:
Since JKL is a straight line, it equals 180
JKM + MKN + NKL = 180
3x+2 + 6x+7 + 90 = 180
Combine like terms
9x+99 = 180
Subtract 99 from each side
9x+99-99= 180-99
9x =81
Divide each side by 9
9x/9 = 81/9
x=9

what is the interval notation for the graph shown below?
[tex](4, \infty)[/tex]
The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"
The right endpoint is positive infinity. We always use a parenthesis with either infinity since we cannot reach infinity
The interval from 4 to infinity is written as [tex](4, \infty)[/tex] which is like saying [tex]4 < x < \infty[/tex]

What is the slope of (3,0) and (9,12)?
Answer:
[tex]m=2[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in your 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{12-0}{9-3}[/tex]
[tex]m=\frac{12}{6}[/tex]
[tex]m=2[/tex]
Answer: m=2
Step-by-step explanation: Use the slope formula to fine the slope m.

Veena is 6 year old
Jack is on a carousel at the rodeo. The diameter of the carousel is 80 feet. Find the position of Jack's seat in point form from the center of the carousel after a rotation of 210 degrees. Explain why the angle you use in the equation is not 2100. Write the two equations you used to set up the problem. the position of Jack's seat is: _______________________Give the exact answer (no rounding).
Answer:
1) The reason, the 210° angle is not used is because, the values of the trigonometric ratios for 210° is the same as the values of the trigonometric ratios for 30°
2) The two equations used to set up the problem are;
The y-coordinate value, y₁ = -40×sin(30°) = -20 feet
The x-coordinate value, x₁ = 40×cos(30°) = 34.64 feet
3) The coordinates of the point location of Jack's seat = (20×√3, -20)
Step-by-step explanation:
The given information are;
The diameter of the carousel = 80 feet
The rotation of the carousel = 210°
Assuming Jack seat was initially on the left side of the center of the carousel and the carousel rotates clockwise, we have;
Final position of the carousel = 210 - 180 = 30° South of East
The radius of the carousel = (80 feet)/2 = 40 feet
The slope of the location of Jack seat = -tan(30°)
The y-intercept = The center = 0
y - y₁ = m·(x - x₁)
The y-coordinate value, y₁ = -40×sin(30°) = -20 feet
The x-coordinate value, x₁ = 40×cos(30°) = 20×√3 = 34.64 feet
The equation in point and slope form is therefore;
y - (-20) = -√3/3×(x - 34.64)
y + 20 = -x·√3/3 + 20
y = -x·√3/3
The reason, the 210° angle is not used is because, the values of the trigonometric ratios for 210° is the same as the values of the trigonometric ratios for 30°
The two equations used to set up the problem are;
The y-coordinate value, y₁ = -40×sin(30°) = -20 feet
The x-coordinate value, x₁ = 40×cos(30°) = 34.64 feet
The coordinates of the point location of Jack's seat = (20×√3, -20)

Find two numbers whose sum is 49. If the greater is 4 more than 8 times the smaller. Solve
Answer:
5 and 44
Step-by-step explanation:
smaller number: x
greater number: 8x + 4
x + 8x + 4 = 49
9x + 4 = 49
9x = 45
x = 5
smaller number: 5
greater number: ?
8(5) + 4 = 40 + 4 = 44
5 + 44 = 49
Hope that helps.

A chemistry book comprises of two sections: organic and non-organic in the ratio
2:8. How much of each type of content will be needed to make a book of 400
pages?
Answer:
Organic = 80pages & Non organic = 320pages.
Step-by-step explanation:
Organic:Non organic
2:8
• 2/10 x 400 = 80
• 8/10 x400= 320
Given parameters:
Ratio of organic to non-organic = 2:8
Total number of pages in the book = 400
Unknown:
Number of pages of organic = ?
Number of pages of non-organic = ?
Ratios establishes the proportion of parts in a whole.
We can find the whole from the part and likewise the part from the whole if we know the ratio;
To solve this problem;
Sum up the ratio ; 2 + 8 = 10
Number of pages of organic = [tex]\frac{2}{10} x 400[/tex] = 80pages
Number of pages of non-organic = [tex]\frac{8}{10} x 400[/tex] = 320pages
We need 80 pages of organic and 320 non- organic pages to make up the chemistry book.

John bought 3 bottles of an energy drink for $4.50. Write an equation relating the total cost y to the number of energy drinks bought x. *
Answer:
Step-by-step explanation:
y = 3 times x
or: y divided by x = 3
John often speed while driving to school in order to arrive on time. The probability that he will speed to school is 0.75. If the probability that he speeds and gets stopped by a police officer is 0.25. Find the probability that he is stopped, given that he is speeding.
Answer:
0.33
Step-by-step explanation:
Given the following :
P(speeding) = p(s) = 0.75
P(being stopped) = p(t)
P(speeding and gets stopped) = p(s n t) = 0.25
Find the probability that he is stopped, given that he is speeding is written as P(t | s) ;
P(t | s) = p(s n t) / p(s)
P(s n t) = 0.25
P(s) = 0.75
Hence,
P(t | s) = 0.25 / 0.75
P(t | s) = 0.33

Fully simplify.
(-2V-49)(5V-100)
(-2v-49)x(5v-100)
Multiply each term in the first parentheses by each term in the second parentheses (foil)
-2vx5v-2vx(-100)-49x5v-49 x (-100)
calculate the product
-10v²-2v x(-100)-49x5v-49 x(-100)
-2vx5v
Multiply the numbers
-10v x v
the same of the other one ok is different how i am doing
-2vx5v
If a term doesn't have an exponent , it is considered that the exponent is 1
-10v^ 1 x v
-10v^1 xv^1
Multiply the terms with the same base by adding their exponents
-10v^1 x v^1
-10v^1+1
to add the numbers using a number line, start from zero
1+1=2
Since 1 is positive, move the point 1 unit to the right
The result is 2
Answer: -10v^2
That's it . Hope it wasn't too hard to understand?
