Answer:
B and C
Step-by-step explanation:
To figure out the average of all of the scores, you add all of the numbers together and then divide by how many numbers there are. The average shows about how well they did. Anne's friends average was 90 and was higher than Joan's friends average which was 75. Then the lowest score was definitely 78. So the answer would be B and C.
Answer:
Option D. The student did not use the correct formula to calculate the area of the segment
Step-by-step explanation:
step 1
Find the area of the isosceles triangle
Applying the law of sines
step 2
Find the area of the sector
The area of the sector is 1/6 of the area of the circle
so
substitute the value
step 3
Find the area of the segment
The area of the segment is equal to the area of sector minus the area of triangle
therefore
The student did not use the correct formula to calculate the area of the segment
Answer:
Shawn
Step-by-step explanation:
We can find the amount of vehicles sold in one week by dividing the total vehicles sold by the number of weeks
Shawn:
36 vehicles / 4 weeks
9 vehicles/week
Brett:
56 vehicles / 7 weeks
8 vehicles/week
9 is greater than 8 so Shawn sells more vehicles per week
Answer:
x=3
Step-by-step explanation:
Simplifying
9x + -4 = 3x + 14
Reorder the terms:
-4 + 9x = 3x + 14
Reorder the terms:
-4 + 9x = 14 + 3x
Solving
-4 + 9x = 14 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-4 + 9x + -3x = 14 + 3x + -3x
Combine like terms: 9x + -3x = 6x
-4 + 6x = 14 + 3x + -3x
Combine like terms: 3x + -3x = 0
-4 + 6x = 14 + 0
-4 + 6x = 14
Add '4' to each side of the equation.
-4 + 4 + 6x = 14 + 4
Combine like terms: -4 + 4 = 0
0 + 6x = 14 + 4
6x = 14 + 4
Combine like terms: 14 + 4 = 18
6x = 18
Divide each side by '6'.
x = 3
Simplifying
x = 3
