Start by isolating the variable on one side by adding 43w^2 to both sides. The equation will read:
25w^2+5=0
<em>*Subtract 5 from both sides*</em>
25w^2=-5
<em>*Divide both sides by 25*</em>
w^2=-1/5
<em>*Take the square root of both sides*</em>
w=√(-1/5)
The square root of -1 is i. The square root of 5 remains √5
The answer is i/√5.
Hope this helps!!
Answer:
314.2
Step-by-step explanation:
Circumference of a circle is π![r{2}](https://tex.z-dn.net/?f=r%7B2%7D)
so 3.142 ×
=314.2
Answer:
For length of side = 3 cm
Area of the square = 9 cm²
For length of side = 10.5 cm
Area of the square = 110.25 cm²
For length of side = π cm
Area of the square = 9.869 cm²
Step-by-step explanation:
The area of a square is given as :
Area = Side²
therefore,
For length of side = 3 cm
Area of the square = ( 3 cm )² = ( 3 × 3 ) cm² = 9 cm²
For length of side = 10.5 cm
Area of the square = ( 10.5 cm )² = ( 10.5 × 10.5 ) cm² = 110.25 cm²
For length of side = π cm
Area of the square = ( π cm )²
= ( π × π ) cm²
= 3.14² cm² [π = 3.14]
= 9.869 cm²
<h2> Answer-:</h2>
There are different combinations you can do.... for example
10 tables of 4 and 20 tables of 6
or
25 tables of 4 and 10 tables of 6
so Im not sure which :/ but the equation would be:
10x+20y=160
or
25x+10y=160
there are different combinations of the two so im not sure T_T
<h2> The End</h2>
Sid will pay $76.26 in total including ta and tip.
Step-by-step explanation:
Given,
Cost of Sid's bill = $62.00
Tax rate = 8%
Tip = 15%
Tax amount = 15% of bill
![Tax\ amount=\frac{8}{100}*62.00\\Tax\ amount=0.08*62.00\\Tax\ amount=\$4.96](https://tex.z-dn.net/?f=Tax%5C%20amount%3D%5Cfrac%7B8%7D%7B100%7D%2A62.00%5C%5CTax%5C%20amount%3D0.08%2A62.00%5C%5CTax%5C%20amount%3D%5C%244.96)
As the tip will be on Pre-tax amount, therefore,
Tip amount = 15% of bill
![Tip\ amount=\frac{15}{100}*62.00\\Tip\ amount=0.15*62.00\\Tip\ amount=\$9.30](https://tex.z-dn.net/?f=Tip%5C%20amount%3D%5Cfrac%7B15%7D%7B100%7D%2A62.00%5C%5CTip%5C%20amount%3D0.15%2A62.00%5C%5CTip%5C%20amount%3D%5C%249.30)
Total amount = Bill + Tax amount + Tip amount
Total amount = 62.00 + 4.96 + 9.30 = $76.26
Sid will pay $76.26 in total including ta and tip.
