Step-by-step explanation:
40/10 simplifies to 4.
40/100 simplifies to 0.40.
Therefore:
Option C should the the correct answer.
Answer:
11.14
Step-by-step explanation:
Mean = sum of numbers / total numbers
the mean of the 7 numbers = sum of the numbers / 7
sum of numbers for the 3 numbers = 10 x 3 = 30
Sum of numbers for the other 4 numbers = 12 x 4 = 48
Sum of the 7 numbers = 48 + 30 = 78
Mean of the 7 numbers = 78 / 7 = 11.14
Answer:
(x, y) = ( 1, 10/3)
Step-by-step explanation:
2x + 3y + 12
6 - 4x + 3y = 12
Simplify the equation:
2x + 3y = 12
-4x + 3y = 6
Multiply both sides by -1:
2x + 3y = 12
4x - 3y = -6
Eliminate one variable by adding the equations:
6x = 6
Divide both sides by 6:
x = 1
Substitute the value of x into the equation:
-4 x 1 + 3y = 6
Solve the equation:
y = 10/3
A possible solution:
(x, y) = ( 1, 10/3 )
Check the solution:
2 x 1 + 3 x 10/3 = 6 -4 x 1 + 3 X 10/3 = 12
Simplify the expression:
12 = 12 = 12
All 3 angles of any triangle always sum to 180°,
So d+10 = 180-(62+38)
d+10 = 180-100
d+10 = 80
d+10-10 = 80-10
d = 70°
Answer:
447 ft
Step-by-step explanation:
Add 417 and 30 together. That will give you the total direct distance between the two. 417+30=447
