Yeah I’m Russian so x+4 = 911
Let's call x = profit from the sweatshirt sales 1) A vendor pays to rock band 13% of the total profit from T-shirts and sweatshirts sold at every concert. 2) the profit from T-shirts sales was $ 1,632 3) The vendor paid the rock band $ 726 after the last concert We then have the following equation: 0.13 * (1632 + x) = 726 Clearing x: (1632 + x) = (726 / 0.13) x = (726 / 0.13) - 1632 = 3953 $ Answer: the profit from sweatshirt sales was 3953 $
(1.3X10^6ft/hr)(2.8X10^3hr)
(1.3*2.8)(10^6*10^3)
Rule (a^b)(a^c)=a^(b+c)
(3.64)(10^(6+3))
3.64(10^9)
3.64X10^9 ft
Technically we only had two significant figures and the answer should be:
3.6X10^9 if we were to express our answer to the correct number of significant figures....
1) $600 deposited at 4% simple interest for one year generates:
$600 * 4% = $600 * 0040 = $24
2) If he wants to earn $132 in interest for the year, he yet needs to generate $132 - $24 = $108 (additional)
3) The interest rate to generate $108 on a deposit of $1200 in a year, at simple interest is:
$1200 * (r) = $108 => r = 108 / 1200 = 0.09 = 9/100 = 9%
Answer: 9%
