Consecutive numbers differ by one. So, if $x$ is the first, the three numbers are

$x,\ x+1,\ x+2$

The sum of the first and third integer is

$x+(x+2)=2x+2$

Answer:

3.5 cubic yards of cement we need.

Step-by-step explanation:

Given : You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. Assume that the depth of the concrete is 4 inches.

To find : How much cement is needed, in cubic feet? How many cubic yards of cement do you need?

Solution :

The length of the side walk is 95 feet long.

The width of the side walk is 3 feet long.

The depth of the concrete is 4 inches.

Convert inches into feet,

1 inch = 0.083 feet

4 inch = $4\times 0.083=0.332$ feet

Volume of the cement required is given by

$V=l\times b\times h$

$V=95\times 3\times 0.332$

$V=94.62\ ft^3$

Converting volume into yards,

$1\ ft^3=0.037\ yd^3$

$94.62\ ft^3=3.50094\ yd^3$

Therefore, 3.5 cubic yards of cement we need.

Answer:

The company's profit be in the year 2008 is $8.3 million.

Step-by-step explanation:

Given:

In the year 2006, a company made $7 million in profit, their profit increased by 9%.

So, we need to calculate the company's profit be in the year 2008.

Now, by putting the formula to find the profit(P) after the two year:

Difference between the year = 2008 - 2006 = 2 year.

So, <u><em>number of years(n) = 2 year</em></u>

<u><em>Rate of profit increasing(r) = 9%</em></u>

<u><em>Amount company made in 2006 (A) = $7 million</em></u><u>.</u>

$P=A(1+\frac{r}{100})^{n}$

$P=7(1+\frac{9}{100})^{2}$

$P=7(1+0.09)^{2}$

$P=7(1.09)^{2}$

$P=7\times 1.188$

$P=8.316$

<em>Profit in the year 2008 would be 8.316 million, and nearest to the tenth of a million dollars is $8.3 as 3 is in the tenth place of the decimal and 1 in the hundredth so rounding will change $8.316 to $8.3.</em>

Therefore, the company's profit be in the year 2008 is $8.3 million.
