Answer: $x - y = 4$

Step-by-step explanation:

$x - 1 = 0$

Add 1 to both sides of the equation , that is

$x - 1 + 1 = 0 + 1$

$x = 1$

Also

$y + 3 = 0$

subtract 3 from both sides of the equation , that is

$y + 3 - 3 = 0 - 3$

$y = -3$

Therefore :

$x - y = 1 - (-3)$

$x - y = 1 + 3$

$x - y = 4$

Answer:

All of the batches of the new blend of concrete made at their plant in a particular week.

Step-by-step explanation:

The population refers to all the subjects or data which which meets the condition or requirement of a certain experiment or research. This means that all the set of similar items or subjects which is of interest in a certain study is the population. In the scenario above, the population will be the set of all the new blend concrete which are made in the plant within a certain week. Thereafter, if a sample is required it will be drawn from these set of data or observation.

Shandra's parents put $1,500 in her bank account for college tuition. At an interest rate

gavmur [86]

Answer:

$6,427.99

Step-by-step explanation:

-We first find the effective annual interest rate as follows:

$i_m=(1+i/m)^m-1\\\\=(1+0.0825/2)^2-1\\\\=0.084202$

#We the use this rate to find the compounded amount after 18 years:

$A=P(1+i_m)^n\\\\=1500(1.084202)^{18}\\\\=6427.99$

Hence, the amount after 18 years is $6,427.99

store A offers successive discounts of 10% one week and 20% the second week. store B offers a one-time discount of 25% the secon

11111nata11111 [884]

The store which offers the greater discount is store B.

<h3>Discount</h3>

Store A:

First week = 10%

= 10/100

= 0.1

Second week = 20%

= 20/100

= 0.2

Total discount = (0.1 + 0.2) / 2

= 0.15

Store B:

25%

= 25/100

= 0.25

Therefore, the store which offers the greater discount is store B.

The following table shows the estimated populations and annual growth rates for four countries in the year 2000. Find the expect

Liula [17]

Answer:

After 25 years the population will be:

Australia: 22271200
China: 1580220878
Mexico: 157380127
Zaire: 112794819

Step-by-step explanation:

Growth rate problem that has a growth rate proportional to the population size can be solved using the equation:

P(t) = P₀eʳᵗ

t is your unit of time. It could be days, or hours, or minutes. It changes depending on each problem. In this problem, t is measured in years because you're jumping from 2000 to 2025. Years just makes the most sense to measure that leap in time.

P(t) is the population at time t. An example in this problem could be P(20) would be the population 20 years after the initial count. or maybe P(12) would be the population 12 years after the initial count. or P(0) would be the initial count of the population.
