Answer:
370
Step-by-step explanation:
Every time, the number adds 7. 66*7 will be 462.
-92+462 is 370
Answer:
13) B
14) A
Step-by-step explanation:
13) Knowing that the interior angles of a triangle add up to 180, we can see that angle A is 53°. To find length c, we can use either sine or cosine. Let's use sine:
sin 37° = b/c = 15.9/c ---> c = 15.9/sin 37 = 26.4
To solve for side a, use cosine:
cos 37° = a/26.4 ---> a = 26.4cos37 = 21.1
14) Again, knowing that the interior angles of a triangle add up to 180, we know that angle B is 52°. This time,let's use cosine (although you may choose sine if you want):
cos 38° = b/16 ---> b = 16cos38 = 12.6
To find side a, use sine:
sin 38° = a/16 ---> a = 16sin38 = 9.9
<em>It is cut off so I do not know whether it is from least to greatest or greatest to least. </em>
If it is from <u>least to greatest</u>, then the answer is:
-2/3, -0.29, -0.27
If it is from <u>greatest to least</u>, then the answer is:
-0.27, -0.29, -2/3
-2/3 as a decimal is -0.66. This would put it at the lowest number in the group. Because these are negative numbers, you have to picture them as being on a number line-you cannot just look at the biggest integers. -0.66 is furthest down the number line, followed by -0.29, and finally -0.27 is closest to 0, making it the largest number in the group.
Answer:
9
Step-by-step explanation:
So perimeter is adding all sides
In this picture, you have all sides, so add them up!
(2a-3)+(3a+1)+(2a) = P
So this expression shows that we're adding all sides that gives us the P, or perimeter :)
