Answer:
<em>There are </em><em>70</em><em> students only in chorus.</em>
Step-by-step explanation:
Total number of students is 250
Out of 250, 180 students took band.
And 60 took band and chorus, i.e this is the intersection of the 2 groups.
The Venn diagram is attached below.
So, the number of students who took only band = 180-60 = 120
Total number of students or sum of the 3 regions is 250.
So, the number of students who took only chorus = 250-180 = 70
Answer:
I think the isosceles triangle
Step-by-step explanation:
Because it has fewer sides and cannot be put in a "Tile" pattern. Not really sureI hope this helps. :)
Answer:
c
Step-by-step explanation:
Answer: 139°
Reasoning:
Angle 3 and 5 are congruent, so you can put their expressions equal to each other and solve.
14x-1=9x+14
To isolate the x to one side, subtract the 9x from the 14x.
5x-1=14
Now to get the constants on one side, add the 1 to the 14.
5x=15
Now divide both sides by 5 to isolate the x.
5x/5=15/5
x=3
Now that we know that, we can figure out angle 3.
9(3)+14
27+14= 41
Angle 3 = 41°
Now that we know what angle 3 is, we can subtract it from 180° to figure out angle 8 since angle 3 and 8 are supplemtary angles, aka linear pairs.
180°- 41°= 139°
<h3>Double checking your answer:</h3>
41°+139°=180°
32.5 square feet. If you do the area formula “A=5v13(13) over 2”
