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:
B. more than zero if no products were made and would then increase in direct proportion to output
Explanation:
Semi-fixed Cost will be "more than zero if no products were made and would then increase in direct proportion to output."
This is because a semi-fixed cost also known as semi-variable cost or mixed cost is a combination of both a fixed factor and a variable factor.
Such that if production was zero some costs would still be incurred. However, as output rises, the variable part of the costs will rise in direct proportion to output.
Answer:
Y = 300
government multiplier 2
output demanded increase by 20
If income tax is applied:
Y = 272.72
multipliers: 2.253775
increase 22.53775 billons
As disclosure it has a larget effect when the income tax is levied based on income rather than a flat rate.
Explanation:
DI = Y - 100
C = 30 + 0.6(Y - 100)
C = 30 - 60 + 0.6Y
C = 0.6Y - 30
Y = C + G + I
Y = (0.6Y -30) + 120 + 30
Y = 120 / 0.4 = 300
C = (0.6)300 - 30 = 150
With C we solve for the multiplier:
150/300 = 0.5
1 / (1 - 0.5) = 2
10 x 2 = 20
If variable that:
C = 30 + 0.6 (0.75Y)
C = 30 + 0.45Y
Y = 0.45Y + 120 + 30
Y = 150/.55 = 272,72
C = 30 + 0.45Y = 152,72
Propensitivity to consume:
152.72/272.72 = 0,5563
multiplier:
1 (1 - PMC) = 2.253775073
10 nillon will icnrease x 2.25377 = 22.54 billons

Although test marketing costs can be high, they are often small when compared with the costs of a major mistake.
<h3>What is meant by test marketing?</h3>
Before a larger release, a product or marketing campaign is made accessible on a restricted basis to test markets with the intention of examining consumer reaction. It's crucial to keep in mind that customers who have been exposed to the product or campaign can unknowingly be a part of a test group.
Standard test markets, controlled test markets, and simulated test markets are the three different types of test markets. The main users of test markets are marketers of consumer packaged goods. Products supplied in packets that people use practically daily are referred to as consumer packaged goods (CPG).
Even while test marketing expenses can be considerable, they are frequently insignificant when weighed against the price of a significant error.
