First find the area of the bathroom . 9ft times 8.5 ft = 76.5 sq ft

76.5 sq ft * $4 = $306

You will need to find the area by multiplying the length and width. 8 1/2 can also be written as 8.5, then we multiply the result by 4 to find out how much money she needs to pay. Since it's $4 per square, it only makes sense to multiply the total tiles by 4. You can see how I solved in the picture provided. So she will have to pay $306

Adaline is designing a garden in the shape of a 45º-45º-90º triangle, with an area of 32 ft2. To the nearest foot, how much fenc
wel

Answer:

27 ft

Step-by-step explanation:

Given: A garden in the shape of a 45º-45º-90º triangle.

Area of triangle= 32 ft²

As given dimension of triangle, we understand that it is a right angle and triangle and since two angles are equal, therefore two sides of triangle are also equal.  

∴ Base and height will be equal.

Assuming base is also as "h"

Now, finding the length of base and height by using area of triangle formula.

Area of triangle=  \frac{1}{2} \times base\times height

⇒32= \frac{1}{2} \times h\times h  

Multiplying both side by 2

⇒64= h^{2}  

Square rooting both side, remember; √a²= a

⇒  \sqrt{64} = h

∴ h= 8 feet

Hence, both base and height of right angle triangle is 8 feet.

Next, finding total fencing required to enclose the garden.

Perimeter of garden is equal to the amount of fencing required by Adaline.

Therefore, finding the length of hypotenous of triangle too.

Using pythogorean theoram.

h^{2} = a^{2} +b^{2}, where a is the height and b is the base of triangle.

⇒ h^{2}= 8^{2}  +8^{2}

⇒ h^{2} = 128

Square rooting both side

⇒h= \sqrt{128}

∴ h= 11.3 feet

Perimeter of garden= base+height+hypotenous

⇒ Perimeter of garden= 8+8+11.3= 27.3\ feet \approx 27\ feet

Hence, 27 feet fencing is required to enclose the garden.

B.. Given that event B is card drawn is blue.

Step-by-step explanation:

Special deck has3 blue and 7 orange cards. The blue cards are numbered 1, 2 and 3. The orange cards are numbered 1, 2, 3, 4, 5, 6 and 7.

We draw one card randomly from the deck, the sample space is

S={b1, b2, b3, o1, o2, o3, o4, o4, o6, o7}

Where,

'b' represents blue card

And 'o' represents orange cards.

Number of elements in the sample space is 10.

Given that event B is card drawn is blue.

B={b1, b2, b3}.

If VZ=p–7 and WY=p–21, what is the value of p?
sveta [45]

Using the midline property;

2wy = vz

2(p - 21) = p - 7

2p - 42 = p - 7

2p - p =  - 7 + 42

p = 35
