Given △PQR≅△STU, m∠R=80°, and m∠S=70°, what is the measure of ∠Q?

Dahasolnce [82]

∆ PQR is congruent to ∆ STU

This means --
P = S
Q = T
R = U

R = 80°
S = P = 70°

So in ∆PQR, we know R = 80° , P = 70° and Q = ?

Using angle sum property of triangle,
P+ Q + R = 180°
70° + 80° + Q = 180°
150° + Q = 180°
Q = 30°

Hope This Helps You!

There is a traffic light at the intersection of Walnut Street and Lawrence Avenue. The traffic light on Walnut Street follows a

Natalija [7]

From the given above, we calculate for the total cycle time by adding up all the durations given for the yellow light, red light, and green. That is,
total time = 30 s + 10 s + 50 s = 90s
Hence, the total time is equal to 90 s. From this, we calculate for the probability that the first light that will be seen is a red light by dividing the duration of the red light in the cycle by the total time.
Probability = (30 seconds) / (90 seconds)
= 1/3

Therefore, the probability that the red light will be seen first is equal to 1/3. The answer is second choice.

zlopas [31]

Answer:

27 km/h (｡◝‿◜｡)

Step-by-step explanation:

Let's take the direction in which Diego is travelling as positive direction. Therefore:

- Diego is travelling at a velocity of +7 km/h, towards the net

- The ball travels at +20 km/h towards the net, with respect to Diego's reference system

Therefore, the velocity of the ball with respect to the net reference system is equal to the sum of the two velocities:

Gil buys 4 books for $16. Then he sells 3 CDs for $27. Write equations for y, Gil’s change in money after buying a book, and for

guajiro [1.7K]

Given:

Gil buys 4 books for $16. Then he sells 3 CDs for $27.

To find:

The equations for y, Gil’s change in money after buying a book, and for x, his change in money after selling a CD, in standard form.

Slope of each equation.

Solution:

Gil buys 4 books for $16.

4 books = $16

1 book = $4

Let n be the number of book purchased, then change in money after buying n book is

$y=-4n$

Here, negative sign represents decrease in money. Here, slope of -4 it means the money decreased by $4 after buying each book.

He sells 3 CDs for $27.

3 CDs =$27

1 CDs =$9

Let c be the number of CDs sold, then change in money after selling m CDs is

$x=9m$

Here, slope of 9 it means the money increased by $9 after selling each CD.
