The odd- and even - number hotel rooms are on different sides of the hall. Room 231 is between witch two rooms

1 answer:

8 0

The first odd number before 231 which would be on the same side of the hall is 229. The first odd number after would be 233.
On the odd side of the hall, the order would be room 229, room 231, room 233.

Given: ΔABC, AC = BC, AB = 3 CD ⊥ AB, CD = √3 Find: AC

valina [46]

Answer:

$\boxed{AC = 2.3}$

Step-by-step explanation:

AD = BD (CD bisects AB means that it divides the line into two equal parts)

So,

AD = BD = AB/2

So,

AD = 3/2

AD = 1.5

Now, Finding AC using Pythagorean Theorem:

$c^2 = a^2+b^2$

Where c is hypotenuse (AC), a is base (AD) and b is perpendicular (CD)

$AC^2= (1.5)^2+(\sqrt{3} )^2$

$AC^2 = 2.25 + 3$

$AC^2 = 5.25$

Taking sqrt on both sides

$AC = 2.3$

I need the thing for the square pizza ill give brainlest to who gets its right

baherus [9]

Answer:

A) The square pizza gives you more delicious (XD) pizza. And 24 (225-201) more pizza.

B) There's more crust on the square pizza then on the circle one, according to 60>50!

Step-by-step explanation:

A)First, let's calculate the area of the round pizza.

We need to find out the radius, and radius= $\frac{diameter}{2}$

So radius=16/2, which is 8.

And a circle's area is $\pi r^{2}$ , so the equation for this round pizza is:

$\pi (8)^{2}$

=64 $\pi$

≅201 $inch^{2}$

Second, we calculate the square pizza's area, which is pretty easy since the equation for a square is: $(Side Length)^{2}$ .

So for this square pizza, the area would be:

$(15)^{2}$

=225 $inch^{2}$

Lastly, we compare the two, 225>201, so the square pizza gives you more delicious (XD) pizza. And 24 (225-201) more pizza.

B)So this problem is actually asking you to find the circumference of the circle and perimeter of the square.

Let's start off with the circle, the formula for circumference is:

$\pi (d)$

We already have the d, (diameter), which is 16, so the circumference of this circle pizza is:

16 $\pi$

≅50 inch

Then we find the a square's, the equation for perimeter is:

4 (side length)

=4(15)

=60 inch

So happily, we found out there's more crust on the square pizza then on the circle one, according to 60>50!

Hoped I helped! And hope you can get full credit with my will elongated answer XD.

Find the equation of the exponential function represented by the table below : X Y

leva [86]

Answer:

f(x) = 0.01 × 2^(x+1)

Step-by-step explanation:

0.02 = 0.01 × 2¹

0.04 = 0.01 × 2²

0.08 = 0.01 × 2³

0.16 = 0.01 × 2⁴

mr Goodwill [35]

Answer:

-2.8

Step-by-step explanation:

Given that:

Mean, μ = 78

Standard deviation, σ = 5

Omar's score, x = 64

The Zscore of Omar's score :

Zscore = (x - μ) ÷ σ

Zscore = (64 - 78) / 5

Zscore = - 14 / 5

Zscore = - 2.8

Hence, Omar's exam score is - 2.8
