Answer:

B. Your estimate is wrong, and it should be $4,752

Step-by-step explanation:

We are given that:

Size of tile = 1yard by 1yard

Let convert yard to feet, so as to find the covered by the tile in feet.

Since 1yard = 3feet

Size of tile = 3feet by 3feet

Area cover by tile = 3x3 = 9ft²

Size of kitchen floor = 24ft by 33ft

Area covered by floor = 24 x 33 = 792ft²

Total number of tile needed for the kitchen floor = Area of kitchen/Area of tiles

= 792/9

= 88 tiles

Given that each tile cost $54

Total cost of 88 tiles = 54 x 88 = $4752

Therefore the answer is

B. Your estimate is wrong, and it should be $4,752

Jack wants to buy a pair of trousers for $60. When he went to the store he found that the price was marked down by 20%. How much
Snowcat [4.5K]
The trousers will cost $48.



60 / 100 = 0.6


20% off so that will make it 80% of 60 so you put the two together by doing:


0.6 * 80 = 48

2x^2+9x-35 factor or foil
notka56 [123]

You would need to facto 2x² + 9x - 35 to get (2x - 5)(x + 7).

We can find this first by dividing the 2x² into 2x and x, which we can put into the brackets:

(2x _ _)(x _ _)

Then we need to find two factors of -35 that have a difference of 9 when one is multiplied by 2, which gives us +7 and -5 as (7 × 2) - 5 = 14 - 5 = 9.

This gives our final answer as:

(2x - 5)(x + 7)

We cannot use foil on this expression as there are no brackets to expand.

I hope this helps!

Answer: Option C.

Step-by-step explanation:

You must use the formula for calculate the volume of a cone, which is shown below:

V_\frac{1}{3}r^2h\pi

Where <em>r</em> is the radius and <em>h </em>is the height.

Based on the figure attached:

r=3in\\h=7in

Substitute these values into the formula for calculate the volume of a cone, then the result is:

V_\frac{1}{3}(3in)^2(7in)\pi

V=65.97in^3≈66in³

 what are irrational numbers/
irakobra [83]
To put it simply, irrational numbers are numbers that cannot be expressed as a fraction. In other words, irrational numbers are numbers that cannot be terminated(stop repeating) or continuously repeated as a single repeating number(.666 or .333 for example). So pi is a irrational number since it repeats but with different numbers repeating each time.
