A counter top is 18 feet long and 3 feet wide. What is the area of the counter top in square meters? Use the conversion 1 foot =

podryga [215]

Answer:

Area of the counter top is $5.02\ m^2$ .

Step-by-step explanation:

Given:

Length of the Counter top = 18 feet

Width of the counter top = 3 feet

We need to find the area of the counter top is square meter;

Solution:

Now we need to find the area of the counter top is square meter.

But given data is in feet so we will first convert feet into meters.

1 foot = 0.305 meter.

So 18 feet = Number of meters in 18 feet.

By Using Unitary method we get;

Number of meters in 18 feet = $18\times 0.305 = 5.49\ m$

Length of the Counter top = 5.49 m

Also 3 feet = Number of meters in 3 feet.

Again Using Unitary method we get;

Number of meters in 3 feet = $3\times 0.305 = 0.915\ m$

Width of the counter top = 0.915 m

Now we know that;

Area of the counter top can be calculated by multiplying Length of the counter top with width of the counter top.

framing in equation form we get;

Area of the counter top = $5.49\times 0.915 = 5.0233\ m^2$

Rounding up to 2 decimals we get;

Area of the counter top = $5.02\ m^2$

Hence Area of the counter top is $5.02\ m^2$ .

Please list a reason why scientific notation is important thank youuu !!

otez555 [7]

The primary reason why scientific notation is important is that it allows us to convert very large or very small numbers into much more manageable sizes. When these numbers are in scientific notation, it is much easier to work with them

How do I solve this?

Readme [11.4K]

Answer:

x ≈ -4.419

Step-by-step explanation:

Separate the constants from the exponentials and write the two exponentials as one. (This puts x in one place.) Then use logarithms.

0 = 2^(x-1) -3^(x+1)

3^(x+1) = 2^(x-1) . . . . . add 3^(x+1)

3×3^x = (1/2)2^x . . . . .factor out the constants

(3/2)^x = (1/2)/3 . . . . . divide by 3×2^x

Take the log:

x·log(3/2) = log(1/6)

x = log(1/6)/log(3/2) . . . . . divide by the coefficient of x

x ≈ -4.419

A graphing calculator is another tool that can be used to solve this. I find it the quickest and easiest.

<em>Comment on alternate solution</em>

Once you get the exponential terms on opposite sides of the equal sign, you can take logs at that point, if you like. Then solve the resulting linear equation for x.

(x+1)log(3) = (x-1)log(2)

x=(log(2)+log(3))/(log(2)-log(3))
