A parallelogram is an easy quadrilateral with two pairs of parallel aspects. the other or dealing with facets of a parallelogram are of equal length and the other angles of a parallelogram are of equal measure. Hence, proved p + q = r.
A parallelogram has four sides overall and two pairs of facets that might be parallel. A square is a parallelogram that has four equal sides. the other facets are parallel and all corners of the rectangular shape the right attitude. A rectangle is a parallelogram that has 4 contrary, parallel, congruent aspects.
proving p + q = r;
q = ∠OCD = ∠BAO ( alternate angle)
In Δ AOB
∠OAb + ∠DBA = p + q -------------------(1)
& ∠AOD + ∠BOA = 180° ------------(2)
Also,
∠OAB + ∠OBA + ∠BOA = 180° --------- some of angle in a triangle.
⇒ ( p + q) + (180° - ∠BOA) = 180° --------using 1 & 2
⇒ p + q - r = 0
⇒ p + q = r

11. The list price of an orange dial Luminox watch is $450. Katz Jewelers receives a tradediscount of 25%. Find the trade discount amount and the net price.
Answers
In order to find the trade discount amount and the net price, you first calculate the 25% of $450. You proceed as follow:
(25/100) x 450 = 112.5
the percentage is divided by 100, an
Then, $112.5 is the 25% of $450. And $112.5 is the discount amount
Next, to calculate the net price, you simply calculate the difference between the intial price ($450) and the price after the discount ($112.5), just as follow:
net price = $450 - $112.5 = $337.5
Hence, the discount amount is $112.5 and the net price is $337.5

A rocket is launched straight up with a velocity of 8.36. What would be the velocity when it lands?
Answers
If the rocket is launched straight up with a velocity of 8.36 then at the velocity of landing the speed of the rocket will also be 8.36.
Given that the rocket is launched straight up with a velocity of 8.36.
We are required to find the velocity when the rocket lands.
Velocity is basically the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference.
When the velocity of rocket while it goes up is 8.36 then the velocity when it lands is also 8.36 because if the velocity will increase then the rocket will crash also.
Hence if the rocket is launched straight up with a velocity of 8.36 then at the velocity of landing the speed of the rocket will also be 8.36.

We have to approximate the area under the curve using the given rectangles.
Each rectangle will have an area that is equal to the width (the interval Δx) times the height (that is f(xi)).

Robin and Dovey have four pet pigeons that they train to race. They release the birds at Robin's house and then drive to Dovey's to collect them. To drive from Robin's to Dovey's, because of one-way streets, they go 3.1 km north, turn right and go 1.7 km east, turn left and go 2.3 km north, turn right and go 0.9 km east, turn left and go 1.2 km north, turn left and go 4.1 km west, and finally turn left and go 0.4 km south. How far do the pigeons have to fly to go directly from Robin's house to Dovey's house? Round your answer to the nearest tenth. (HINT: draw a picture!) *
Answers
Let the north and east with a positive sign, so, the south and west are negative signs
Because of one-way streets, they go 3.1 km north, turn right and go 1.7 km east, turn left and go 2.3 km north, turn right and go 0.9 km east, turn left and go 1.2 km north, turn left and go 4.1 km west, and finally turn left and go 0.4 km south.
So, the resultant horizontal distance = 1.7 + 0.9 - 4.1 = -1.5 km
The resultant vertical distance = 3.1 + 2.3 + 1.2 - 0.4 = 6.2 km
So, the direct distance will be calculated using Pythagorean theorem :
So, the distance d =
[tex]\begin{gathered} d=\sqrt[]{(-1.5)^2+(6.2)^2}=\sqrt[]{2.25+38.44} \\ \\ d=\sqrt[]{40.69}=6.37887 \end{gathered}[/tex]Rounding the answer to the nearest tenth

We have to find the monthly revenue received when the cost is $17
That is d=17
Now we substitute d=17 in the given equation to find the monthly revenue
We get,
