Answer:


Step-by-step explanation:

Since triangles have a total degree count of 180 degrees you would subtract 36 + 63 which equals 99 from 180 which would be 81 so

x= 81 degrees

A flat line is also equal to 180 degrees so you subtract 81 (x) from 180 to get 99, so

z=99 degrees

You repeat the beginning process and do 13 + 99 which equals 112 and subtract it from 180 which is 68, so

y=68 degrees

Answer: x = 81 degrees, y = 68 degrees, z = 99 degrees

Step by step:

Use fact that angles sum up to 180 degrees in any triangle.

Left triangle:

180=36+63+x

x = 180-99 = 81 degrees

Use the fact that x and z are supplementary angles:

180 = x + z = 81 + z

z = 180 - 81 = 99 degrees

And again using triangle angle sum of 180 degree:

180 = 13 + z + y = 13 + 99 + y

y = 180 -112 = 68 degrees

A truck traveling 45 miles per hour and a train traveling 60 miles per hour cover the same distance. The truck travels 2 hours l
anygoal [31]

Answer:

6-hours

D = C + T

Step-by-step explanation:

The following equations represent the total distance travelled by each vehicle, the truck (C) and the Train (T) where x is the amount of time travelling in hours...

C = 45x

T = 60x

Since the truck traveled 2 hours longer than the train we can add this value to the variable x in the truck's distance equation and then make both equations equal one another to calculate the number of hours before they cover the same distance...

45(x+2) = 60x  ... distribute 45 evenly

45x + 90 = 60x ... subtract 45x from both sides

90 = 15x  ... divide both sides by 15

6 = x

Finally, we can see that both vehicles would have traveled the same distance at the 6-hour mark. Now to calculate the total distance traveled (D) we can use the following equation...

D = C + T

A teacher gave a test to three classes that contained 27, 25, and 23 students. A total of 18 students scored an A on the test. B
salantis [7]
Ratio of classes A, B, C = 4 : 6 : 5, respectively
4 + 6 + 5 = 15
So, class A represents 4/15 of the TOTAL population
Class B represents 6/15 of the TOTAL population
Class C represents 5/15 of the TOTAL population

So, weighted average of 3 groups combined = (4/15)(65) + (6/15)(80) + (5/15)(77)
= 260/15 + 480/15 + 385/15
= 1125/15
= 75
