What are similar triangles?
Similar triangles are two triangles that, while not sharing the same size, have the same proportions and angles measurements. Their corresponding angles are equal and the corresponding sides are in the same ratio.
Triangle PQR is similar to triangle STU because their angles are the same, and they share the same proportions in regards to their side lengths.
To find the unknown side of a similar triangle, set up two ratios equal to each other that represent the ratios of each triangle.
n is the hypothenuse of triangle PQR, so in your ratio, n should be in a fraction with 13, the hypothenuse length of triangle STU.
The fraction that n and 13 will be set equal to should also be the same side of the different triangle. (so either both of them are the shortest legs or both of them are the longest legs of their triangles)
Let's check each answer:
n is in the denominator and 13 is in the numerator. Great! 36 is the longest leg of triangle PQR and 12 is the longest leg in triangle STU, great! This choice is wrong, however. This is because both denominators and numerators should be set equal to their respective triangles. n is in triangle PQR, while 12 is in triangle STU, so they can not be set equal to each other.15 and 5 are both the shortest legs in their triangles, great! Unfortunately, 12 and n are both not hypothenuses, so this answer is incorrect. 15 and 5 are both the shortest legs in their respective triangles, but, again, n and 12 are not both hypothenuses.n is in the denominator and 13 is in the numerator. Great! 36 is the longest leg of triangle PQR and 12 is the longest leg in triangle STU, great! And, n is set equal to 36 (they are in the same triangle) and 13 is set equal to 12 (they are in the same triangle). This is the correct answer.*To check if your answer is correct, solve for n by cross multiplication and plug in your answer into the fraction. Both sides should simplify to the same fraction*

Answer:
D: PQ is congruent to QR

In a rectangle, there are a few statements that are always true. Opposite sides are congruent and parallel and all angles meet at 90 degrees. However, adjacent sides (sides that are touching/share a vertex) are not necessarily congruent. They can be; if they are then that rectangle is a square. Nevertheless, if adjacent sides are not congruent, then it is still a rectangle, so long as they meet at a right angle.

1000=58.3x+227.9
Step 1: Flip the equation.
58.3x+227.9=1000

58.3x/58.3 = 772.1/58.3
x=13.243568
Use the bar graph. Astronauts installed 15 new tiles on the outside of the space station they spent 390 minutes on the task. each tile took the same amount of time to install. draw a bar in the graph to show the time needed to install a tile. Explain
Answers
Answer:
11. It will take about 26 minutes to install a singular tile.
12. It will take about 10 more minutes to install a light than it does to install a cable.
Step-by-step explanation:
11. Since installing 15 new tiles took a total of 390 minutes and each tile took the same amount of time, you can divide the total amount of time by the number of tiles.
390/15= 26 minutes
It will take about 26 minutes to install a single tile.
12. By looking at the chart it can be assumed that installing a light takes about 22 minutes since it is in the middle of 20 and 24 minutes. Installing a cable only takes 12 minutes.
22-12= 10 minutes
It takes about 10 minutes longer to install a light than it does a cable.
It took about 26 minutes to install a single tile and 10 minutes longer to install a light than it does a cable.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given,
Installing 15 new tiles took a total of 390 minutes and each tile took the same amount of time,
We have to divide the total amount of time by the number of tiles.
390/15= 26 minutes
It will take about 26 minutes to install a single tile.
By observing the chart, it can be assumed that installing a light takes about 22 minutes since it is in the middle of 20 and 24 minutes. Installing a cable only takes 12 minutes.
22-12= 10 minutes
It takes about 10 minutes longer to install a light than it does a cable.
Hence, it took about 26 minutes to install a single tile and 10 minutes longer to install a light than it does a cable.

A cannonball is released at an angle of 20˚ at a velocity of 12m/s. Calculate the horizontal velocity of the object. What kinematic formula must be used to solve this problem?.
Answers
The horizontal velocity of the cannonball is released at an angle of 20˚ at a velocity of 12m/s is 11.276 m/s.
What is Velocity?Velocity is the rate of change of position with respect to time. It is a scalar quantity.
We know that the velocity is a scalar quantity therefore, it can be divided into two components such that the first component is the vertical component which is equal to the (V sinθ), while the other component is the horizontal component(V cosθ), where V is the velocity and θ is the angle of the velocity from the positive x-axis.
Now, in order to calculate the horizontal velocity of the cannonball we can write,
[tex]\rm V_x = V\ Cos\theta[/tex]
[tex]V_x = 12 (Cos\ 20^o)\\\\V_x = 11.276\rm\ m/s[/tex]
Hence, the horizontal velocity of the cannonball is released at an angle of 20˚ at a velocity of 12m/s is 11.276 m/s.

Answer:
$31,950 dollars
Step-by-step explanation:
Given the following question:
Initial price of the car is $30,000...
The car has an increase tax of 6.5% (which means 6.5% of the initial price of the car is the sales tax.)
In order to find the total cost of the car, we need to find 6.5% of $30,000 and then add that number to the initial price to have the answer.
[tex]\frac{6.5\times30000}{100} =6.5\times30000=19500\div100=1950[/tex]
[tex]30000+1950=31950[/tex]
