What is the length of the arc by a central angle of 85 degrees and a radius of 8cm to the nearest tenth of a cm?
9514 1404 393
Answer:
11.9 cm
Step-by-step explanation:
Arc length is given by ...
s = rθ . . . . . . θ is the central angle in radians
Your central angle is 85°, so is (85/180)π radians = 17/36π radians.
Then the arc length is ...
s = (8 cm)(17/36π) ≈ 11.9 cm
The length of the 85° arc is about 11.9 cm.

Answer:
From a standard deck of cards, one card is drawn. What is the probability that the card is black and a jack? P(Black and Jack) P(Black) = 26/52 or ½ , P(Jack) is 4/52 or 1/13 so P(Black and Jack) = ½ * 1/13 = 1/26 A standard deck of cards is shuffled and one card is drawn.

Actually Welcome to the concept of ratios.
Since the above ratios are equal to each other, we get value of x as,
==> 3/12 = 5/x
==> x = 12*5 / 3
==> x = 60/3
==> x = 20
hence the value of x = 20.

3. Choose the equation of the line parallel to the line 5 = -10x - 5y that passes through the point (-2,5). A y=-2x + 1 C y=x-5 By=-12x + 5 D y = 5x + 11
Answer:
y = -2x + 1
Step-by-step explanation:
The equation is in standard form, first, we need to convert it to slope-intercept form.
5 = -10x - 5y
5 + 10x = -5y
Divide both sides by -5 to isolate y variable.
y = -2x - 1
If the line is parallel, the slope remains the same.
To find the y-intercept, you need to plug the values of x and y into the equation, which is y = 2x + b
5 = -2(-2) + b
5 = 4 + b
1 = b
The equation is -2x + 1
i need help with the last two. I forgot the formula and wondering if you will help me find which one is and isnt a triangle
Answer:
3. D) 26, 7, 31
4. B) 6, 34, 27
Step-by-step explanation:
Both #3 and #4 use the same strategy: the two shorter sides' sum has to be greater than the longer side.
#3:
2 + 8 is 10, which is less than 13. So A wouldn't form a triangle.
12 + 22 is 34, which is the length of the longer side. So B wouldn't form a triangle either.
14 + 18 is 32, which is less than 40. So C wouldn't form a triangle.
7 + 26 is 33, which is greater than 31. So D would form a triangle.
D. 26, 7, and 31 are the only lengths of the ones shown that form a triangle.
#4:
17 + 18 is 35, which is greater than 19. So A would form a triangle.
11 + 22 is 33, which is greater than 25. So C would also form a triangle.
5 + 18 is 23, which is greater than 20. So D would form a triangle.
6 + 27 is 33, which is less than 34. So B wouldn't form a triangle.
B. 6, 34, and 27 are the only lengths of the ones shown that don't form a triangle.

Side YQ and side XP are altitudes to the congruent sides of isosceles triangle WXY. Keisha is going to prove side YQ ≅ side XP by showing they are congruent parts of the congruent triangles QXY and PYX.
By the triangle congruence we can use the SSA method to prove the base angles are congruent.
What do you mean by congruent triangles?If two or more triangles are congruent, it depends on how big their sides and angles are. The three sides and three angles of a triangle determine its size and shape, accordingly. Two triangles are said to be congruent if the pairings of respective sides and corresponding angles are equal.
These are exactly the same size and shape. There are several different congruence conditions that triangles might meet.
In the figure given,
It is necessary to demonstrate the congruence of the triangles PYX and QXY.
Both triangles have the same XY base.
PX must equal QY because the lines PX and QY are perpendicular on congruent sides.
Angles PYX and QXY are equal since the axiom "Angles opposed to equal sides are equal" states that they are.
As a result, it can be shown that the two triangles PYX and QXY have two sides and an equal angle.
As a result, using SSA criteria, the two triangles will be congruent.
Hence, option C is the best one.

find quotient and reminder of 4x³-12x²+15x-5÷2x-1
Answer:
The quotient is 2x² - 5x + 5, while the remainder is 0
Step-by-step explanation:
Given polynomial function;
4x³-12x²+15x-5 and a factor of 2x - 1
The quotient and remainder of the polynomial is calculated using the long division method;
2x² - 5x + 5
------------------------
2x - 1 √ 4x³-12x²+15x-5
- (4x³ - 2x²)
----------------------------
-10x² + 15x - 5
- ( -10x² + 5x)
--------------------------------
10x - 5
- (10x - 5)
-----------------------------------------
0
Therefore, the quotient is 2x² - 5x + 5, while the remainder is 0.

graph 3x+6y=18 In the box below, enter the y value when x = 2.
Answer:
y = 2
Step-by-step explanation:
3x + 6y = 18
3(2) + 6y = 18
6 + 6y = 18
Since 18 - 6 = 12, y will equal 2.
6 + 6(2) = 18
6 + 12 = 18
The coordinates to graph the equation would be (2, 2).

a bike rental company charges $12, which includes the first 30 minutes of biking. thereafter, the company charges an additional $0.25 per minute. write a numeric sequence for the first 5 minutes of the 30 minutes.
Answer:
0.4, 0.8, 1.2 ,1.6 ,2.0
Step-by-step explanation:
First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.
Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.
Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.
The numeric sequence is 0.4, 0.8, 1.2 ,1.6 ,2.0
The calculation is as follows:
Here we have to divide $12 by 30. That will equal 0.4 a minute.
Now if we add 0.4 for each minutes
So the series be like
0.4 for the first, 0.8 is 2 minute and so on.

Bobby and Marie are running a lemonade stand.They spend $12 on all their materials and charge $1.50 for each cup of lemonade. If they sell 20 cups of lemonade, how much money would they make(or lose)?
Answer:
$18
Step-by-step explanation:
First you would multiply $1.50 by how many cups of lemonade they sell (20). Your answer for this would be $30. After that you want to subtract the $12 from the $30, because they spent $12 on materials. Then you get $18, which is your answer. Hope this helps :)

The area of the composite figure is 34 square units.
The formula for the area of a trapezoid is:
Area = (1/2) × (sum of bases) × height
Here, the sum of the bases is 10 + 6 = 16, and the height is 5.
Thus, the area of the trapezoid before the rectangle is cut out is:
Area of trapezoid = (1/2) × 16 × 5 = 40 units²
The height of the rectangle is 2, and the length is 3.
Therefore, the area of the rectangle is:
Area of rectangle = length × height
= 3 × 2
= 6 units²
To find the area of the composite figure, we subtract the area of the rectangle from the area of the trapezoid:
Area of composite figure = Area of trapezoid - Area of rectangle
= 40 units² - 6 units²
= 34 units²
Therefore, the area of the composite figure is 34 square units.
