Mathematics

Mariana [72]3 years ago

Answer:

Step-by-step explanation:

what makes these tough is that you have to remember that the total of the angle is known,  you know it to be 180 ° , so since you know the total just set all the part equal to that

180 = 4x + 6x-20 + 5x - 10

now you can slove for x with your mad algebra skilz  :) if you don't have those yet. it's okay.. most people don't  :D  Super hero's and math whizzes only, seem to have those.  :D

180 = 15x -30

210 = 15x

14 = x  

now that we know what x is , plug it into the angle BCE

BCE = 6(14) -20

BCE = 84 -20

BCE = 64 °

132 books are printed in 2 hours, 264 books are printed in 4 hours, and 528 books in 8 hours, how many books are printed in 3 ho
maxonik [38]
So the unit rate is 66:1
then you do 66*3=198
198:3
then you do the same thing 66*7=462
462:7
lastly you do 66*15=990
990:15

If Janet scored an 85% on her test she answered 34 questions correctly how many questions were on the test
Wittaler [7]
40 questions. You set up a proportion, mutiply 34 by a 100 and get 3400. Then you divide 3400 by 85 and you get ur answer. You could also try guessing by putting in random values you think are the whole number and multiplying them by 0.85. So if you guess 44 is the whole and try checking it by multiplying it by .85 and get a value thats higher than the value the percentage is equal to you try another smaller value. So if 44 doesn't work you can try 40. 40 times .85 is 34 so your answer of 40 questions is correct.

Help with this please.
Ivanshal [37]

Answer:

  • True
  • True

Step-by-step explanation:

This question asks you to compare the coordinates of the vertex of each function.

__

The vertex of the function is its minimum, the point where the graph stops decreasing and starts increasing. It is the lowest point on the graph.

<h3>f(x)</h3>

The vertex is (-4, -1). The minimum is -1, located at x = -4.

<h3>g(x)</h3>

The vertex is (1, -25). The minimum is -25, located at x = 1. We know this is the minimum because there are no g(x) values that are lower (more negative).

<h3>comparison</h3>

The minimum of f(x), -1, is greater than the minimum of g(x), -25. TRUE

The x-value of f(x) at its minimum, -4, is less than the x-value of g(x) at its minimum, 1. TRUE
