A parking lot has the shape of a rectangle. A scale drawing for the parking lot measures 6cm by 20cm. The scale is 1cm : 15m. Find the area of the parking lot.

Surface area of the rectangle prism is 88 sq. units.

Given:

height of the rectangle prism (h) = 4 units

width of the rectangle prism (w) = 2 units

length of the rectangle prism (l) = 6 units

Recall:

Formula for surface area of a rectangle prism is:

[tex]SA = 2(lw +wh +lh)\\[/tex]

Plug in the values:

[tex]SA = 2(6\times 2 +2\times4 +6\times4)\\SA = 2(12 + 8 + 24)\\SA = 2(44)\\SA = 88[/tex]

Therefore, the surface area of the rectangle prism is 88 sq. units.

Answer: 0.6 is ten times as much as 0.06

Step-by-step explanation:

We are given a statement:

0.6 is ten times as much as

Let the number be considered as 'x'

'Times' in the above statement means multiplication operation.

So, the equation for the given statement becomes:

[tex]0.6=10\times x[/tex]

To solve the value of 'x', we shift the number '10' to other side of the equation and operation applied will be division.

Solving the above equation, we get:

[tex]0.6=10\times x\\\\x=\frac{0.6}{10}=0.06[/tex]

Hence, 0.6 is ten times as much as 0.06

The population of Pleasanton is 17 % higher. (Right choice: D)

According to the statement, the population of Pleasanton is reduced by a factor of 0.9 in the 1980s and increased by a factor of 1.3 in the 1990s. The increase rate is found by means of this formula:

[tex]x =[(0.9)\cdot (1.3)-1]\cdot 100[/tex]

[tex]x = 17\,\%[/tex]

The population of Pleasanton is 17 % higher. (Right choice: D)

The population of Pleasanton at the end of the 1990s is 17% higher than the population in 1980.

To compare the population of Pleasanton in the 1990s with the population in 1980, we need to consider the changes that occurred in each decade. In the 1980s, the population decreased by 10%. This means that if the population in 1980 was represented by 100, it would have decreased to 90 by the end of the decade.

In the 1990s, the population increased by 30%. Using the population of 90 at the beginning of the decade, the population at the end of the 1990s would be 90 + (30% of 90) = 90 + 27 = 117.

So, the population of Pleasanton at the end of the 1990s is 117, which is 17% higher than the population in 1980. Therefore, the correct answer is D) It is 17% higher.

Also, 5280 ft = 1 mi

Given speed =  4500 feet per second

To convert it into miles per hour.  we divide it by 5280 and multiply it by 3600 we get

[tex]4500\times\dfrac{3600}{5280}\\\\=3068.18181818\approx3068.18\text{ miles per hour}[/tex]

It will take 20 months for the costs of Apartment A and Apartment B to be the same.

To find out how many months it will take for the costs of Apartment A and Apartment B to be the same, we need to set up an equation. Let's say it takes x months for the costs to be equal. The equation would be: 1000 + 1200x = 1500 + 1175x. We can solve this equation to find the value of x.

First, we can simplify the equation by subtracting 1175x from both sides: 1000 + 25x = 1500. Then, we can subtract 1000 from both sides to isolate the variable: 25x = 500.

Finally, we can divide both sides of the equation by 25 to solve for x: x = 20. Therefore, it will take 20 months for the costs of Apartment A and Apartment B to be the same.

When there is only one solution, a set of linear regression is persistent and independent. The diagrams of the platform's lines intersect at precisely one spot if this is the case. If a set of linear equations would have no resolutions, it is inconsistent. There is only one solution pair for an autonomous state (x,y). The sole solution is the intersection of the two lines.
