In ΔPQR, the measure of ∠R=90°, QR = 8 feet, and RP = 3.9 feet. Find the measure of ∠P to the nearest degree.

Kipish [7]

Answer:

64°

Step-by-step explanation:

Check the attachment for the diagram. Since the triangle has one of its angle as 90°, it is a right angled triangle.

Using the SOH CAH TOA trigonometry ratios:

Since ∠P is opposite to side QR,

QR = opposite side = 8ft

RP = adjacent side = 3.9ft

According to TOA

Tan∠P = Opposite/Adjacent = QR/RP

Tan∠P = 8/3.9

Tan∠P = 2.05

∠P = arctan 2.051

∠P = 64°

Can someone plz help with this question idk how to do it im stooopid

Answer: 96 square units (choice B)

==============================================

Explanation:

Triangle OBI has a base of OI = 12 units along the horizontal component, and CB = 8 is the vertical component or the height.

area of triangle OBI = 0.5*base*height

area of triangle OBI = 0.5*12*8

area of triangle OBI = 48 square units

--------------------------------------

Now find the area of the trapezoid GNIO. The two horizontal components are the parallel bases GN = 4 and OI = 12. The height of this trapezoid is the vertical component CD = 6, where point D is added on to be at location (0,-6) on the graph.

area of trapezoid = (height*(base1+base2))/2

area of trapezoid GNIO = 6*(4+12)/2

area of trapezoid GNIO = 48

Coincidentally, the triangle and trapezoid both have the same area

--------------------------------------

The last thing to do is add the two areas of the triangle and trapezoid

total area = (area of triangle OBI) + (area of trapezoid GNIO)

total area = (48) + (48)

total area = 96 square units

A new pop-up restaurant serving high-end street tacos just opened and is expected to have high demand based on the chef's prior

Answer:

1. c

2. f

3. d

Step-by-step explanation:

This type of queuing model is an example of "single-channel, single-phase" process.

However, from the information given:

The inter-arrival rate = 10 customers per hour

Arrival time = 6 minutes

Service time = 5 minutes

∴

utilization = service time/arrival time

= 5/6

Time on queue $T_q = p \times \dfrac{utilization }{1 - utilization} \times \dfrac{Cv_a^2 -Cv_b^2}{2}$

$T_q = 5 \times \dfrac{5/6 }{1 -5/6} \times \dfrac{(2.58^2 -0.75^2)}{2}$

$T_q = 25 \times 3.60945$

$T_q = 90.24 \\ \\ T_q \simeq 90 \ mins$

Thus, customer waiting in the queue line is;

$= \dfrac{T_q}{q} \\ \\ = \dfrac{90}{6} \\ \\ \mathbf{=15}$

Thus, new customers will have to wait in a total time of;

= waiting time + service time

= 90 + 5

= 95 minutes.

I need Help plsssss!!!!!

laiz [17]

Answer:

2x - 3

x - 9

Step-by-step explanation:

The root of a problem is the x value that makes the equation equal to zero.

If the factored form of the equation is (2x-3)(x-9) that means if either 2x - 3 or x - 9 is equal to zero, the entire equation will equal zero, because zero times any number is equal to zero.

Therefore you must solve for (2x-3)=0 and (x-9)=0
