Let
x = minutes used for jogging
y = minutes used for handball
z = minutes used for cycling
Th total time spent is 1 hour (60 minutes), therefore
x + y + z = 60
Because Mike jogs as long as he cycles, therefore
x = z
Therefore
2x + y = 60
or
y = 60 - 2x (1)
Jogging consumes 10 calories/min, handball consumes 9 calories/min and cycling consumes 12 calories/min.
The calories consumed in 60 minutes is 580, therefore
10 x + 9y + 12z = 580
Because x = z,
22x + 9y = 580 (2)
Substitute (1) into (2).
22x + 9(60 - 2x) = 580
22x + 540 - 18x = 580
4x = 40
x = 10
y = 60 - 2x = 40
z = x = 10
Answer:
10 minutes of jogging
40 minutes of handball
10 minutes of cycling.
Answer: decreases
Explanation: The following practice is done by the central bank in the situation of inflation when there is an excess supply of money in the economy.
The central bank tries to decrease the funds by selling the govt bonds to the banks. This results in decrease in funds from banks as they have to buy such bonds from their respective funds.
Answer: C. There has been a decline in the foreign exchange value of the nation’s currency.
Explanation:
The Demand curve of a country can be written as an equation which is
C+I+G+(X-M)
C is consumption, I is investment, G is government expenditure, X is exports, M is imports and X-M is net exports.
When ever consumption, investment, government expenditure or net exports increase the demand curve shifts to the right and whenever they decrease the demand curve shifts to the left.
In this case when the value of the currency foreign exchange declines, the country reduce its imports because they are now more expensive as your currency's value is declining and the exports will increase because they will now be cheaper to foreign buyers as their currency is now gotten stronger. This decrease in imports and increase in exports will increase net exports and an increase in net exports will shift the demand curve to the right
