A man bought 42 stamps, some 13¢ and some 18¢. How many of each kind did he buy if the cost was $6.66?

OverLord2011 [107]

Let's call the 13¢ stamps a and the 18¢ stamps b: a+b = 42 and therefore a= 42-b (formula 1) 0.13a+0.18b= 6.66 In this formula, substitute the value of a according to formula 1: 0.13(42-b)+0.18b= 6.66 Multiply on the left to get rid of the parenthesis: 5.46-0.13b+0.18b= 6.66 Subtract 5.46 from both sides: -0.13b+0.18b= 1.20 Add on the left: 0.05b= 1.20 Divide both sides by 0.05 b= 24 You have 24 18¢ stamps and: 42-24= 18 13¢ stamps Check: (24 x 0.18) + (18 x 0.13)= 6.66 Correct.

Heart beats 2,320 times during 20 minutes of rowing. While resting the heart is beating 16 times in 15 seconds. What is the diff

Mrac [35]

Answer: 0.87 times per second (Or 52.2 times per minute)

Step-by-step explanation:

You need to make the conversion from minutes to seconds.

Remember that 1 minute has 60 seconds. Then 20 minutes to seconds is:

$(20minutes)(\frac{60seconds}{1minute})=1,200seconds$

Find the number of times the heart beats in 1 second when it is rowing:

$x_1=\frac{(2,320times)}{1,200seconds}=1.93\ times\ per\ second$

Find the number of times the heart beats in 1 second when it is resting:

$x_2=\frac{(16times)}{15seconds}=1.06\ times\ per\ second$

Then the difference is:

$difference=(1.93-1.06)\ times\ per\ second\\difference=0.87\ times\ per\ second$

(Or 52.2 times per minute)
