Answer:
13. x=11; MN=65°; NP=115°; NQP=245°
15. x=9; AD=108°; BC=23°; DC=139°; DBC=221°
Step-by-step explanation:
13.The marked arcs are congruent, so we can equate the given expressions for their measures:
10x -45 = 6x -1
4x = 44 . . . . . . . . . add 45-6x
x = 11 . . . . . . . . . . divide by 4
The arc measures are found by using the value of x in the corresponding expression. Arcs around a circle total 360°.
arc MN = (10(11) -45)° = 65°
arc NP = 180° -65° = 115°
arc NQP = 360° -NP = 245°
__
15.The sum of arcs around a circle is 360°. We can use this fact to write an equation involving the given expressions. Clockwise from A, we have ...
90 +(2x +5) +(17x -14) +12x = 360
31x = 279 . . . . . . . subtract 81, collect terms
x = 9 . . . . . . . . . divide by 31
The arc measures are found by using the value of x in the corresponding expression.
arc AD = 12(9)° = 108°
arc BC = (2(9) +5)° = 23°
arc DC = (17(9) -14)° = 139°
arc DBC = 360° -DC = 221°

how do you round 81.59 to the nearest whole number?
Answer:
The number (81.59) will round to 82.
Step-by-step explanation:
First, let us understand what the question means by "whole numbers".
What are whole numbers?Whole numbers are such integers that are positive. (Except 0, which is a non-positive and non-negative integer).
Whole numbers: 0, 1, 2, 3, 4, 5, 6....
If the number before the decimal is smaller than 50, then the number will round down. If the number before the decimal is greater than or equal to 50, then the number will round up.
We can see that 81.59 is between two integers (81 and 82). Therefore, 81.59 can either round down to 81 or round up to 82.
Since the number after the decimal (81.59) is greater than 50, the number rounds up to 82. Therefore, the number (81.59) will round to 82.

If a canoe travels 6 miles per hour downstream, and 2 miles per hour p stream, how many miles per hour will it go in still water?
Answer:
4 miles per hour
Step-by-step explanation:
The given relations allow us to write two equations.
__
The downstream speed is the sum of the canoe speed and the stream speed:
6 = c + s
The upstream speed is the difference of the canoe speed and the stream speed:
2 = c - s
Adding these two equations, we get ...
8 = 2c
4 = c . . . . . divide by 2
The canoe speed in still water is 4 miles per hour.
Answer:
4 Miles an hour

Answer:
3π
Step-by-step explanation:
The arc length is just a fraction of the circumference of the circle which we know is represented by the equation L=2πr.
The radius is given ad 6. So the circumference is:
2*π*6=12π
Now, since the angle of the arc is 90°, this is 1/4 of the circle.
This means that the arc length of this section will be 1/4th of the total circumference which is:
12π/4=3π

determine the quadtratic that has the following square root (5/3, 7/3)
Answer:
9x^2 - 36x + 35.
Step-by-step explanation:
One would be (x - 5/3)(x - 7/3) <------ in factor form.
Getting rid of the fractions by multiplying each term by 3:
= (3x - 5)(3x - 7)
Converting to standard form
= 3x*3x -7*3x - 5*3x + 35
= 9x^2 - 36x + 35.
Verify the property p × q = q × p of the rational numbers using p =5/28 and q=49/35
The commutative property of multiplication is verified for the case when p =5/28 and q=49/35 because we get p × q = 0.25 = q × p
What is the difference between verification and proof?Proof usually is generalized, ie, it applies for all possible cases of the given condition, or a large set of cases. But vertification is a check for single special case.
For this case, we've to verify that p × q = q × p when p =5/28 and q=49/35
For p =5/28 and q=49/35 we get:
[tex]p \times q = \dfrac{5}{28} \times \dfrac{49}{35} = \dfrac{5 \times 49}{28 \times 35}\\\\\\p \times q = \dfrac{245}{980} = 0.25[/tex]
Also, we get:
[tex]p \times q =\dfrac{49}{35} \times \dfrac{5}{28} = \dfrac{49 \times 5}{35 \times 28}\\\\\\p \times q = \dfrac{245}{980} = 0.25[/tex]
Thus, we get: p × q = 0.25 = q × p
Hence, verified.
Thus, the commutative property of multiplication is verified for the case when p =5/28 and q=49/35 because we get p × q = 0.25 = q × p

The minimum amount to the nearest dollar according to the line of best fit from the graph is $26 because as y = $26, x = 0.
What is the line of best fit?The line of best fit is a line that runs across a scatter plot of data points and best reflects the connection between them.
Let's make an assumption from the image below that;
x = the total amount($) of her customers’ bills and;y = her total daily wages.We know that x = 0 at the y-intercept;

PLEASE HELP!! URGENT If a fair coin is tossed 4 times, what is the probability, to the nearest thousandth, of getting exactly 3 tails?
Using the binomial distribution, it is found that there is a 0.25 = 25% probability of getting exactly 3 tails.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
A fair coin is equally as likely to result in heards or in tails, hence p = 0.5.The coin is tossed 4 times, hence n = 4.The probability of getting 3 tails is P(X = 3), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{4,3}.(0.5)^{3}.(0.5)^{1} = 0.25[/tex]
0.25 = 25% probability of getting exactly 3 tails.

Answer:
y = x/2
Step-by-step explanation:
y = -x has a negative slope so cross this one out.
y = 2x has a steeper slope that would be above the black line so cross this one out
y = 0.001x has a slope that acends very slowly so cross this one out.
y = x/2 is the best match.
Some terminology:
⇒what is the slope
⇒ is the steepness of the line
⇒calculated by dividing the rise over the run
⇒ rise is the change in the y-direction
⇒ run is the change in the x-direction
⇒look at the diagram I attached
⇒ how to find the slope in a linear equation
⇒look to the coefficient of the 'x' variable
⇒ that is the slope
Ex. For the line y = x, the slope is 1
⇒A line with a positive slope rises from left to right while a line with a negative slope falls from left to right.
Ex. y=x has a positive slope and thus is rising
We want to find the equation that could represent the blue line
⇒ let's look into each equation and see whether they work or not
First case: [tex]y = -x[/tex]
⇒The equation given has the line falling, when the graph in the
equation is rising
⇒ not the answer
Second case: [tex]y=2x[/tex]
⇒ the equation given has the line that has a bigger slope than the
the equation shown, which has a smaller slope than y = x
⇒ not the answer
Third case: [tex]y=\frac{1}{2}x[/tex]
⇒ the equation given fits the requirement of having a rising slope that
is smaller than y = x
⇒ is a possible answer
Fourth case: [tex]y = 0.001x[/tex]
⇒ the equation given has a slope that is almost horizontal when the
line shown in the graph doesn't
⇒ not the answer
Thus after examing all the choices:

Please Help !! What is the volume of a cylinder with base radius 2 and height 9?
Answer:
The cylinders volume is 113.04 cubic inches
Step-by-step explanation:
The volume of a cylinder can be represented by the formula : V = π*r^2*h
So, now that we have the formula, we can simply plug in the values, and we have the volume of the cylinder.
V = π * 2^2 * 9
V = π * 4 * 9
It says to use 3.14 as π.
V = 3.14 * 4 * 9
V = 113.04
The cylinders volume is 113.04 cubic inches

the third angle?
A 30°

C, 60 degrees
Step-by-step explanation:
Right Triangle, with a 30 degree angle:
Given degrees:
90 (Right Triangle)
30
90+30 = 120
180-120 = 60
180 Degrees total in a triangle, you simply subtract the measure you have to fidn the third one.
Answer:
The measure of the third angle is 60°.
Step-by-step explanation:
We are given a right triangle that has a 90 degree and two other angles that are unknown.
Since one known angle is 90° and another angle given is 30° then the third angle must be 60°. All triangles must add up to 180°.
180° - 90° - 30° = 60°.
Here is an image of the demonstration/explaining types of triangles.
