Given:

The expression is:

2\sqrt{27}+\sqrt{12}-3\sqrt{3}-2\sqrt{12}

To find:

The simplified form of the given expression.

Solution:

We have,

2\sqrt{27}+\sqrt{12}-3\sqrt{3}-2\sqrt{12}

It can be written as:

=2\sqrt{9\times 3}+\sqrt{4\times 3}-3\sqrt{3}-2\sqrt{4\times 3}

=2(3\sqrt{3})+2\sqrt{3}-3\sqrt{3}-2(2\sqrt{3})

=6\sqrt{3}-\sqrt{3}-4\sqrt{3}

=\sqrt{3}

Therefore, the correct option is A.

Riya is applying mulch to her garden. She applies it at a rate of 250,000 cm^3 for every m^2 of garden space
Fudgin [204]
Rate is the change in one variable in relation to another variable. Generally, rate is calculated as follows:

R = ΔV1/ΔV2

Where
R = Rate
ΔV1 = Change in variable 1
ΔV2 = Change in variable 2

In the current scenario,
ΔV1 = 250,000 m^3 of mulch applied
ΔV2 = 1 m^2 of garden space

Therefore,
Rate of applying much is, R = 250,000/1 = 250,000 m^3/m^2

A home improvement store sold wind chimes for $30 each. A customer signed up for a free membership card and received a 5% discou
dsp73

the final price of the wind chime is $29.925 .

<u>Step-by-step explanation:</u>

Here we have , A home improvement store sold wind chimes for $30 each. A customer signed up for a free membership card and received a 5% discount off the price. Sales tax of 5% was applied after the discount. We need to find What was the final price of the wind chime . Let's find out:

Initially we have , 5% discount in $30 i.e.

⇒ (30(5))/100

⇒ (150)/100

⇒ $1.5 , So now price becomes $30 - $1.5 = $28.5 . At this amount there's 5% tax i.e.

⇒ (28.5(5))/100

⇒ (142.5)/100

⇒ $1.425

So now price becomes $28.5 + $1.425 = $29.925 . Therefore , the final price of the wind chime is $29.925 .

A large ice chest holds 62 liters of water. A smaller chest holds 4/5 as much water
dedylja [7]

Answer:

Step-by-step explanation:

Since a large ice chest holds the water = 62 liters

And smaller chest holds the water = \frac{4}{5} of the larger ice chest

                                                         = \frac{4}{5}\times 62

                                                         = \frac{248}{5} liters

Therefore, fraction that represents the amount of ice water in the smaller ice chest will have 0 in the first box, 248 in the numerator and 5 in the denominator.

0\frac{248}{5}

David made a class banner out of a large rectangular piece of paper. He cut a
Irina18 [472]

Answer:

100 in²

Step-by-step explanation:

The area of the banner is equal to the area of the initial rectangle minus the area of the cutout triangle.

The rectangle has a height of 8 inches and width of 14 inches, so its area is:

A = (8 in) (14 in) = 112 in²

The triangle has a base of 8 inches and a height of 3 inches, so its area is:

A = ½ (8 in) (3 in) = 12 in²

So the area of the banner is 112 in² − 12 in² = 100 in².
