8) perimeter mean add the sides so, 8+8=16
9) area u multiple the sides so since the area is 10 and the length is 2 the width is 5
10)14
Answer:
the simple multiplier is equal to 4
Step-by-step explanation:
In an economic model,
Y= C + I + G + (X - M)
the average expenditure Y must be equal to the totality of the output
If C = 3 + 0.75Y
where;
marginal propensity to consume MPC = 0.75
Then,
Y = 3 + 0.75Y + 2 + 1
Y = 6+0.75 Y
Y - 0.75 Y = 6
0.25 Y = 6
Y = 6/0.25
Y = 24
However, the simple multiplier can be expressed as:
= 4
I think it’s either a or c
Answer:
It will take the 20 years for the population to quadruple.
Step-by-step explanation:
Exponential population growth:
An exponential model for population growth has the following model:
In which P(0) is the initial population and r is the growth rate, as a decimal.
It grows with a doubling time of 10 years.
This means that . We use this to find r. So
So
Determine how long it will take for the population to quadruple.
This is t for which P(t) = 4P(0). So
It will take the 20 years for the population to quadruple.
Answer:
28
Explanation:
area of the cloth on the table: 6*4= 24
area of the extra cloth: 4*1=4
4+24=28
