Answer:
marked price = $69,000
Step-by-step explanation:
cost price = $60,000
profit
= 15%
= 15% × cost price
= 15/100 × $60,000
= $9000
marked price
= cost price + profit
= $60,000 + $9000
= $69,000
(6.4 x 10^8 meter/sec) x (1 km / 1,000 meter) x (3,600 sec/hour) =
(6.4 x 10^8 x 3,600 / 1,000) km/hour =
177-7/9 km/hour
To increase by a percentage, multiply by the 1+(the percentage/100). i.e. in this case to find 25% we'd multiply by 0.25, so to increase by 25% we basically find 125% of it, which involves multiplying by 1.25.
8*1.25 is 10, so the spider ate 10 bugs this month.
You threw the baseball 40 feet.
This can be represented as two right triangles. The legs of your friend's triangle, the forward distance and distance right, are 15 and 20. Using the Pythagorean theorem, we find the diagonal distance from your friend's starting point:
20²+15²=c²
400+225=c²
625=c²
Take the square root of both sides:
√625=√(c²)
25=c
The legs of your right triangle are 12, your distance forward, and 9, your distance right:
12²+9²=c²
144+81=c²
225=c²
Take the square root of both sides:
√225=√(c²)
15=c
The total diagonal distance is 25+15=40 feet.
