Given QT = SR, QV = SU, and the diagram, prove that triangles QUT and SVR are congruent. Write a paragraph proof.

QveST [7]

Answer:

Triangles QUT and SVR are congruent because the defining two sides and an included angle of triangles QUT and SVR are equal

Step-by-step explanation:

Here we have QT = SR and

QV = SU

Therefore,

QT = √(UT² + QU²)........(1)

RS = √(VS² + RV²)..........(2)

Since QS = QU + SU = QV + VS ∴ QU = VS

Therefore, since SR = QT and QU = VS, then from (1) and (2), we have UT = RV

Hence since we know all sides of the triangles QUT and SVR are equal and we know that the angle in between two congruent sides of the the triangles QUT and SVR that is the angle in between sides QU and UT for triangle QUT and the angle in between the sides RV and VS in triangle SVR are both equal to 90°, therefore triangles QUT and SVR are congruent.

José, vecino de mi calle, me ofrece $3840 por mi computadora, con lo que ganaría el 28% del costo. Siete días después se la vend

Ierofanga [76]

The first thing we must do for this case is to determine the cost.
For this, we make the following rule of three:
3840 -------------> 128%
x ------------------> 100%
Clearing x we have:
x = (100/128) * (3840)
x = 3000
We now look for the percentage earned when making the sale.
For this we make the following rule of three:
3000 -------------> 100%
3750 ------------------> x
Clearing x we have:
x = (3750/3000) * (100)
x = 125
Then, the percentage earned is:
125-100 = 25%
Answer:
I won 25% of the cost when making the sale.

Raffle tickets are sold and 6 prizes are available for the lucky draw. A total of 1,356 raffle tickets are sold for 4/5 dollars

sesenic [268]

Answer:

<u>US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.</u>

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Number of raffle tickets sold = 1,356

Cost of each raffle ticket = US$ 4/5

Number of prizes = 6

Cost of each prize = US$ 8 3/10

2. How much money was raised from the raffle tickets?

For easier calculation, let's convert the fraction numbers to decimal numbers:

Cost of each raffle ticket = US$ 4/5 = US$ 0.80

Cost of each prize = US$ 8 3/10 = US$ 8 + 0.30 = US$ 8.30

Now, we use this formula to calculate how much money was raised and the profits:

Profits = (Number of tickets sold * Cost of each ticket) - (Number of prizes * Cost of each prize)

Replacing with the real values, we have:

Profits = 1,356 * 0.80 - 6 * 8.30

Profits = 1,084.80 - 49.80

Profits = 1,035

<u>US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.</u>
