I believe C because 1840+14%x2which would be the two years = 2355.20
Answer:
<h2>50.8°</h2>
Step-by-step explanation:
First, we need to use the Pythagorean Theorem to find the third side. We will then use the law of cosines to find the angle.
2√15² = 2√6² + b²
60 = 24 + b²
Subtract 24
36 = b²
b = 6
Now, that we have all three sides, we will use the law of cosines to figure out the angle.
c² = a² + b² - 2abCosC°
Substitute the values in.
6² = 2√15² + 2√6² - 2(2√15)(2√6)CosC°
36 = 60 + 24 - 2(37.947331922)CosC°
36 = 60 + 24 - 75.894663844CosC°
36 = 84 - 75.894663844CosC°
Subtract 84
-48 = -75.9CosC°
0.63241106719 = CosC°
Arccos (0.63241106719) = 50.77176844°
The largest acute angle is approximately 50.8°

Step-by-step explanation:
There are 28 right handed students in class
<em><u>Solution:</u></em>
Given that, there are 32 students in a class
The ratio of left-handed students to right- handed students is 1 : 7
Let the number of left handed students be 1x
Let the number of right handed students be 7x
<em><u>To find: Number of right handed students in school</u></em>
Total number of students = 32
number of left handed students + number of right handed students = 32
1x + 7x = 32
8x = 32
x = 4
number of right handed students = 7x = 7(4) = 28
There there are 28 right handed students in class
D has the same answer. D has the same answer, because a means -14 + 8 which equals -6 which isn’t equal to the answer to the first one (-22). The next one you switch the - to a + and the -8 to 8 so it would equal 22. C equals -6 which also doesn’t equals the first one. So the last one is right because one you add to negative so still end up with a negative.
