The floor of a room is being covered with tile. An area one half
tangare [24]

Answer:

Only the floor area \frac{3}{8} has been covered

Step-by-step explanation:

Assuming that the floor of the room is rectangular, then its area is equal to the product of its length times its width.

A = lw

Let's now call A 'the area that was covered with tiles.

We know that half the length was covered, then:

l' = \frac{1}{2}l

w' = \frac{3}{4}w

So:

A' = \frac{1}{2}l(\frac{3}{4}w)

A' = \frac{3}{8}lw

Finally:

A' = \frac{3}{8}A

Austin borrowed money from a credit union for 4 years and was charged simple interest at an annual rate of 5% the total interest
Reika [66]

Given:

Rate of simple interest = 5%

Time = 4 years

Total interest = $160

To find:

The amount borrowed by Austin from a credit union.

Solution:

The formula for simple interest is:

I=\dfrac{P\times r\times t}{100}

Where, P is principal, r is the rate of interest and t is the number of years.

Putting I=160,r=5,t=4 in the above formula, we get

160=\dfrac{P\times 5\times 4}{100}

160=\dfrac{20P}{100}

160=\dfrac{P}{5}

Multiply both sides by 5.

800=P

Therefore, Austin borrowed $800 from a credit union for 4 years.

You are designing the garden of your dream and you are going to start with a blank canvas. That means killing everything before
Aleks [24]

Answer:

2.5 bottles or 3 bottles

Step-by-step explanation:

Given that :

Dimension of lot :

22.5 yds by 20.4 yds

Area of lot = 22.5 * 20.4 = 459 yd²

Volume per bottle of herbicide = 12 fl oz

1.1 fl oz combined with water treats an area of 155 ft²

Number of 1.1 fl oz from 12 fl oz that can be obtained : 12 / 1.1 = 10.90

1 yard² = 9 feet²

459 yard² = (459 * 9) = 4131 feet²

Number of 151 feet² that can be obtained from 4131 feet²

4131 feet² / 155 ft²

= 27.3576 times

= 27.3576 / 10.909

= 2.507

This means he'll have to buy a minimum of 3 bottles if a fraction of a bottle can't be purchased.
