Answer:
20%
Step-by-step explanation:
An equation is 14=x/100*70 or 14=(x%)*70, either one works
solve for x:
- 14=x/100*70
- 14/70=x/100 (Divide each side by 70)
- 1/5=x/100 (Simplify 14/70)
- 100/5=x (Multiply each side by 100 to isolate x)
- x=20 (Simplify 100/5)
- 20% (Rewrite as a percent)
hope this helps!!
81,149, 274.... adding three numbers from the last would help you
like if you take 7 = 4 + 2 +1
or 13 = 7 + 4 +2
similarly 44+24+13 = 81
81+44 +24 = 149
149 + 81 +44 = 274
hope you get it!
Answer:
a - 6%
b - $7.50
Step-by-step explanation:
The answer for a
the only items that had sales tax were $3.00 and $0.50. The total tax for the both was $0.21 so you can find what percent 0.21 is of 3.00 + 0.50 o 3.50. Do this by dividing the percent you are looking for, 0.21, by what it is the percent of 3.50. 0.21 / 3.50 = 0.06. then you multiply the number you got, in this case 0.06 by 100 to find the percentage so it is 6%
The answer for b
Here you can just take the subtotal, $13.00, and subtract all the other prices and you will be left with the price of the top. 13.00 - 3.00 - 2.00 - 0.50 = 7.50. So the answer is $7.50
Ok so I like to go in steps with these questions- first draw a picture and identify your variables.
W=width
L= 3w-1
Now we know that length times width gets us area so we plug in our variables into the area equation.
200 = w(3w-1)
When you foil that equation you end up with a quadratic : 3w^2-w-200 = 0
Either factor that or use the quadratic formula to get
w= 8.33 and w= -8
Since you can't have a negative dimension you need to use 8.33 and plug it back into your length equation.
Final answer:
w= 8.33ft
l= 23.99ft
*Now I simplified the decimals a little bit so you end up with 199.8ft^2 for the area so just add a few decimals on here and there*
