36 divided by 4.50 = 8

The cost of the house 10 years from now in the case when inflation rate should be 3% is $282,222.44.

Since

The house cost is $210,000

The time period is 10 years

And, the rate of interest is 3%

So,

[tex]= \$210,000 \times (1 + 0.03)^{10[/tex]

= $282,222.44

Hence, The cost of the house 10 years from now in the case when inflation rate should be 3% is $282,222.44.

Answer:

It should be 100 days sample so that the margin of error will be 39.2 tons or less

Step-by-step explanation:

We are given that A coal company wants to determine a 95% confidence interval estimate for the average daily tonnage of coal that it mines.

[tex]\alpha = 0.05[/tex]

To Find two tailed critical value using Z table

[tex]Z_{\frac{\alpha}{2}}=Z_{\frac{0.05}{2}}=\pm 1.96[/tex]

Margin of error = ME = 39.2

[tex]\sigma = 200[/tex]

Formula : [tex]n = (\frac{Z_{\frac{\alpha}{2}} \times \sigma}{ME})^2[/tex]

[tex]n = (\frac{1.96 \times 200}{39.2})^2[/tex]

n=100

Hence it should be 100 days sample so that the margin of error will be 39.2 tons or less

Answer:

y = -1/3 x + 7

Step-by-step explanation:

The constant in the end doesn't matter; what matters is the slope. To find a perpendicular slope, all you have to do is take the reciprocal of the slope and multiply it by -1. As mentioned before, the constant in the end doesn't matter, so the answer could also be y = -1/3x + 10, y = -1/3x -1/2, etc...

Answer:

Y=2x

Step-by-step explanation:

The complete table is given as follows -

Time (in hours)                        Snow (in inches)

0                                                      1

1                                                       2

2                                                      4

6.5                                                  13

[x]                                                   [2x]

The equation that shows the amount of snow that has fallen after [x] hours can be written as y = 2x

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is that snow Is falling steadily such that after 2 hours, 4 inches of snow has fallen.

In 2 hours → 4 inches of snow has fallen.

Then, in 1 hour → (4/2) → 2 inches of snow has fallen.

So, in 6.5 hours → 2 x 6.5 → 13 inches

Hence, in x hours → 2x inches

The complete table is shown below

Time (in hours)                        Snow (in inches)

0                                                      1

1                                                       2

2                                                      4

6.5                                                  13

x                                                      2x

The equation that shows the amount of snow that has fallen after [x] hours can be written as -

y = 2x

Therefore, the complete table is given as follows -

Time (in hours)                        Snow (in inches)

0                                                      1

1                                                       2

2                                                      4

6.5                                                  13

[x]                                                   [2x]

The equation that shows the amount of snow that has fallen after [x] hours can be written as y = 2x

The required number of employees being laid off is 90.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Given that,

The number of employees laid off last year was 75.

The percentage increase in laid off  for present year is 20%.

The number of employees laid off can be calculated as follows,

75 + 20% of 75

= 75 + 20/100 × 75

= 75 + 15

= 90

Hence, the number of employees laid off in the present year is 90.

Answer:

The function Q(t) = 4.5 billion (1.013)^t will give the population in t years

Step-by-step explanation:

Here, we want to write a function

The growth percentage is 1.3% = 1.3/100 = 0.013

The function Q(t) will be an exponential function and it will be represented as;

Q(t) = I ( 1 + r)^t

where I is the initial world population at 1980 = 4.5 billion

r is the growth percentage = 1.3% = 0.013

t is the time in years

Substituting these values, we have;

Q(t) = 4.5 billion (1 + 0.013)^t

Q(t) = 4.5 billion (1.013)^t

Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

10−4v=−2−4(−3+v)

Step 1: Simplify both sides of the equation.

10−4v=−2−4(−3+v)

10+−4v=−2+(−4)(−3)+(−4)(v)(Distribute)

10+−4v=−2+12+−4v

−4v+10=(−4v)+(−2+12)(Combine Like Terms)

−4v+10=−4v+10

−4v+10=−4v+10

Step 2: Add 4v to both sides.

−4v+10+4v=−4v+10+4v

10=10

Step 3: Subtract 10 from both sides.

10−10=10−10

0=0

Answer:

The length of the third side is 3x

Step-by-step explanation:

Algebraic Expressions

This problem deals with the ability to manage algebraic expressions in two variables.

Recall the perimeter of a triangle is the sum of its three sides. We already know the perimeter of the triangle is:

P=13x+5y

We also know the lengths of two of its sides are 2x+y and 8x+4y. The sum of those sides is:

S2=2x+y+8x+4y

Joining like terms:

S2=10x+5y

The third side must be the difference between the perimeter and the sum above:

S3=13x+5y-(10x+5y)

Operating:

S3=13x+5y-10x-5y

Joining like terms:

S3=3x

The length of the third side is 3x

Answer:

Step-by-step explanation:

supplementary angle

7x + 9 + 5x + 3 = 180

12x = 180 - 3 - 9

x = 168 / 12

x = 14

plugin x=14 into the equation

= 7x + 9

= 7(14) + 9

= 107°

plugin x=14 into the equation

= 5x + 3

= 5(14) + 3

= 73°

Let's solve your inequality step-by-step.

4(x+1)<4x+3

Step 1: Simplify both sides of the inequality.

4x+4<4x+3

Step 2: Subtract 4x from both sides.

4x+4−4x<4x+3−4x

4<3

Step 3: Subtract 4 from both sides.

4−4<3−4
