Answer:
• It is possible to divide the seventh graders into teams of equal sizes.
,
• 13 students should be on each team.
Explanation:
The seventh grade of Wilson consists of three classes; one with 28 students, one with 29, and one with 34. Therefore, the total number of students in seventh grade is:
He wants each team to have between 4 and 8 students.
Therefore:
• It is possible to divide the seventh graders into teams of equal sizes.
,
• 13 students should be on each team.
3)Principal Amount = P = $7200
Interest rate = r = 4% = 0.04
Time = t = 8 years
Formula for compounding is:
Using the values, we get:
Therefore, the compounded amount will be $9853.70
4)Principal Amount = P = $7200
Compounded Amount = A = $9853.70
Interest Earned = Compounded Amount - Principal Amount
So,
Interest Earned = 9853.70 - 7200 = $2653.70
Therefore, $2653.70 will be earned as interest over a period of 8 years.
Answer: $42
Step-by-step explanation:
His total pay is $52.50 = 8.47x6
if he spent 1/5 then he has 4/5 left. 4/5 times 52.50 = 4(10.50 = $42

Formula
---------------------------------------------
Sum of all exterior numbers = 360°
---------------------------------------------
Apply Formula
---------------------------------------------
z + 45 + 55 + 78 + 74 + z = 360
---------------------------------------------
Combine likes term
---------------------------------------------
2z + 252 = 360
---------------------------------------------
Take away 252 from both sides
---------------------------------------------
2z = 360 - 252
2z = 108
---------------------------------------------
Divide by 2 on both sides
---------------------------------------------
2z = 108
z = 108 ÷ 2
z = 54
---------------------------------------------
Find z + 45
---------------------------------------------
z + 45 = 54 + 45
z + 45 = 99°
---------------------------------------------
Answer: 99°
---------------------------------------------
Answer:
112.6°
Step-by-step explanation:
Using cosine law:
20² = 11² + 13² - 2(11)(13)cos(A)
110 = -286cos(A)
cos(A) = -5/13
A = 112.6198649
