Answer:
73
Step-by-step explanation:
you write 12 instead of b
The largest area that can be enclosed will be that of a square (140 ft)/4 = 35 ft on a side. Such a square has an area of (35 ft)² = 1225 ft², not enough for the garden to be 1300 ft². This tells us the solution to the equation you're being asked to write is non-real.
_____
Putting the given numbers in the area equation, you have
... 1300 = 70w -w²
Multiplying by -1 and completing the square, we have
... w² -70w +35² = -1300 +35²
... (w -35)² = 1225 -1300 = -75
Taking the square root shows us the solution is non-real.
... w - 35 = ±√(-75) = ±5i√3
... w = 35 ± 5i√3 . . . . . . . . . after adding 35. These are complex solutions.
Since we know that Zack must pay $11.00 per $100 monthly, we just need to divide the total amount of the loan, $1,087, by $100 to check how many times he must pay $11.00 each month:
Now we know that he must pay $11.00 10.87 times each month, so the last thing we are going to do to find his monthly payment is multiply both quantities:
We can conclude that Zack's monthly payment is $119.57
Answer:
1,1 and 3,-7
Step-by-step explanation:
1=x
1=y
they are both in positive
x=3
y=-7
here 3 is in positive and 7 is in negative
Answer:
- solution to both: 2, 4
- solution to inequality only: -2, 4.25, 3 1/4
- not a solution: 9 1/2
Step-by-step explanation:
Using x for the variable, the inequality will be ...
9.50 +3.50x ≤ 35
3.50x ≤ 25.50
x ≤ 51/7 ≈ 7.3
Anna cannot buy negative snacks, and she cannot buy fractional snacks. Of the numbers listed, only 2 and 4 are integers between 0 and 7 (inclusive). The values below 7.3 are all solutions to the inequality. The value 9 1/2 is too large to be a solution to the inequality.
Only 2 and 4 are solutions to both the problem and the inequality.
9 1/2 is not a solution.
