Answer:
The length of a side of the flag is 7.2inches
Step-by-step explanation:
Let length = x
Let hypotenuse = x+3
Using Pythagoras' Theorem:
x^2 + x^2 = (x+3)^2
x^2 + x^2 = x^2 + 6x + 9
2x^2 = x^2 + 6x + 9
×^2 - 6x - 9 = 0
x=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)
×=[6+sqrt.72]/2
×=7.2inches
×=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)
x=[6-sqrt.72]/2
×=-1.2(rej)
(PS. sqrt is square root)
(Correct me if i am wrong)
We have the next inequation
8-4x<56
-4x<56-8
-4x<48
-x<48/4
-x<12
x>-12
Solution: x>-12 or (-12,+∞)
Answer:
y = 3, y = 5, y = -1
Step-by-step explanation:
What you do is you substitute the x values into the x.
<em>y + 2(-1) = 5</em>
<em>y + -2 = 5</em>
y = 3
<em>y + 2(0) = 5</em>
y = 5
<em>y + 2(4) = 5</em>
<em>y + 6 = 5</em>
y = -1.
Answer:
The total cost of a bicycle after the tax = $900.8
Step-by-step explanation:
Given
- The cost of a bicycle before tax = 837.95 (let say in $)
To determine
The total cost of the bicycle with a sales tax include
The tax amount can be calculated by multiplying Sales tax i.e. 0.075 with the cost of bicycle before tax i.e. 837.95.
Thus,
Tax amount = 7.5% × 837.95
= 0.075 × 837.95
= $62.85
Thus, the tax amount is: $62.85
Total cost after the tax can be calculated by adding the Tax amount and the cost before tax.
Therefore,
The total cost of a bicycle after the tax = $62.85 + $837.95
= $900.8
Hence, the total cost of a bicycle after the tax = $900.8
