From the question, we understand that QR = ST.
This implies that triangles QRP and STP are congruent.
i.e. △QRP ≅ △STP is true
The length of the minor arcThe given parameters are:
Angle, Ф = 99
Radius, r = 1
The length of the arc is:
L = Ф/360 * 2πr
So, we have:
L = 99/360 * 2π * 1
Evaluate
L = 198/360π
Divide
L = 11/20π
Hence, the length of the minor arc is 11/20π

Answers
The maximum value of the objective function p if p = 180x + 250y is 3020
How to determine the maximum value?The coordinates of the feasible region are given as;
(14, 2), (0, 9), (6, 8), and (10, 3)
The objective function is given as:
P = 180x + 250y
Substitute the coordinates of the feasible region in the above function
P = 180 * 14 + 250 * 2 =3020
P = 180 * 0 + 250 * 9 = 2250
P = 180 * 6 + 250 * 8 = 3080
P = 180 * 10 + 250 * 3 = 2550
The maximum value in the above computation is:
P = 180 * 14 + 250 * 2 =3020

There are two squares.
The perimeter of square x is half the perimeter of square y.
Let the side of the square x be a and the side length of the square y be b. Then we have
Perimeter x = Perimeter y / 2
4a = 2b
2a = b
Then the area of the square x will be
Area of square x = (2a)²
Area of square x = 4a²
Then the area of the square y will be
Area of square x = (b)²
Area of square x = b²
Then the area of square x will be one-fourth of the area of square y.
Thus, the correct option is C.

Answers
Using the monthly payment formula, it is found that the amount he will have to pay is given as follows:
a. $151.73.
What is the monthly payment formula?It is given by:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
In which:
P is the initial amount.r is the interest rate.n is the number of payments.In this problem, the parameters are given as follows:
P = 2513.77, r = 0.1066, n = 1.5 x 12 = 18.
Hence:
r/12 = 0.1066/12 = 0.008883.
[tex]A = 2513.77\frac{0.008883(1 + 0.008883)^{18}}{(1 + 0.008883)^{18} - 1} = 151.73[/tex]

Select the correct answer from the drop-down menu. a machine needs two of its gears replaced. you find two gears, one manufactured 5 years ago and the other manufactured 10 years ago. the specification sheet says that the chance of gear failure is 5% after 5 years and increases to 8% after 10 years. if the gears on the machine are not linked to each other, the probability that both replacement gears will fail is %.
Answers
Based on the probability that each gear will fail and the fact that the gears are not linked, the probability that both will fail is 0.4%.
What is the probability that both gears will fail?Because the gears are not linked together, the probability that both will fail can be found as:
= Probability that gear fails after 5 years x Probability that gear fails after 10 years

there are 13 out of 52 diamond cards.
and there are 26 out of 52 black cards.
so, for the first card to be diamond the probability is
13/52 = 1/4 = 0.25
but now, he does not put the card back.
he pulls the second card out of 51 possible cards.
the desired cases are still 26.
so, the probability to pull a black card as the second card under the restriction that the first card was a diamond is
26/51 = 0.509803922...
the probability for that combined event is then
1/4 × 26/51 = 26/204 = 13/102 = 0.12745098...

Carolyn:
45% = 0.45
We multiply the orignal price with 0.45 to see how much it increased.
[tex]20(0.45) = 9[/tex]
We then add it to the original price
[tex]20+9 =29[/tex]
Emily:
31% = 0.31
We multiply the orignal price with 0.31 to see how much it increased.
[tex]20(0.31) = 6.2[/tex]
We then add it to the original price
[tex]20+6.2=26.2[/tex]
