Answer= 59.8mph

So since it takes 3h of 50mph to get from Ashdown to Bridgetown Carol drives for 150miles. Because 3*50 is 150.
Then divide 60 by 70 which is 0.857. Then times 0.857 by 60 to see how long it took her , which is 51 mins. Add 3h and 51mins which gets you 3.51h.

Then add 150 and 60 to get 210. Divide 210 by 3.51 then you get 59.8 mph

BARSIC [14]

Answer:

You should receive 286.0821056 US dollars

Step-by-step explanation:

* Lets explain how to solve the problem

- The exchange rate is USD/EURO 0.6991

- That means 1 USD = 0.6991 EURO

- You have 200 EURO

- You want to convert them to US dollars

∵ 1 dollars = 0.6991 euro

       USD  :  EURO

           1     :  0.6991

           x     :   200

∴ \frac{1}{0.6991}=\frac{x}{200}

- By using cross multiplication

∴ 0.6991 x = 200

- Divide both sides by 0.6991

∴ x = 286.0821056

∵ x represents the amount of US dollars

∴ <em>You should receive 286.0821056 US dollars</em>

a 2014 mustang originally costs $25000.00 and depreciates at a rate of 8% per year. What is the cost of the car after 7 years?
frutty [35]
$11,000 will bet the cost in 7 years

Given:

Original cost: $25,000

Depreciation rate: 8%

Term: 7 years

Formula for Depreciation:

A = C ( 1 - ( r ) (t) )

A = Future Value

C = Original Cost

r = rate

t = term

Solution:

Substitute the given values to the formula for depreciation.

A = $25,000( 1 - ( 0.08)(7))

A = $25,000( 1 - .56 )

A = $25,000(0.44 )

A = $11,000
