Answer:
Step-by-step explanation:
- A = 1/2(b₁ + b₂)h
- A = 1/2(8 + 4)*6 = 36 m²
Answer and Step-by-step explanation:
Given
ax + by = c
qx + ry = s
(a) the equation has no solutions if a/q = b/r ≠ c/s, when this happens, we say the system of equations has no solution. For example
x + y = 3
x + y = 5
Subtracting first equation from the second we have:
0 = 2 which is impossible.
(b) the equations have infinite solutions if a/q = b/r = c/s, for example
x + y = 2
x + y = 2
Subtracting the first equation from the second we have
0 = 0, since this is always true, then it has infinite solutions.
(c) the equations have unique solutions if a/q ≠ b/r, for example
x + y = 2
x – y = 1
Adding the first and second equation we have
2x = 3, we can get x from here and definitely y, so we have just one solution.
Answer:
a. 8/24 or 1/3 a day
b. 45/60 or 3/4 a hour
c. 1/7 of a week
d. 4/12 or 1/3 a year
Step-by-step explanation:
Simply divide by the conversion you want to set.
60 seconds is 1 hour
24 hours is 1 day
7 days is 1 week
3-4 weeks per month (depending on the month and year)
12 months a year
Answer:
53 degrees
angle DCE is congruent to angle DAE.
Answer: The correct answers are $45.15, $247.25 and $129
Step-by-step explanation:
In order to solve the problems you need to multiply each percentage by his gross monthly pay.
$2,150 x .021 = $45.15
$2,150 x .115 = $247.25
$2,150 x .06 = $129
