Two local hotels, X and Y, rent out rooms nightly. Let X represent the number of rooms hotel X rents out nightly, and let y repr

esent the number of rooms hotel Y rents out nightly. The mean of X is 49, and the mean of Y is 58. Which answer choice correctly calculates and interprets the mean of the sum, S = X+Y? 1 O Ns = 53.5; the hotels can expect to rent out 53.5 rooms, on average, each night. Ws = 53.5; on one randomly selected night, the total number of rooms rented out will be 53.5. Os = 107; the hotels can expect to rent out 107 rooms, on average, each night. ONs = 107; on one randomly selected night, the total number of rooms rented out will be 107.

Fine the measure of the angle formed by the radius and the side of a regular dodecagon.

Elden [556K]

Answer:

Option D.75°

Step-by-step explanation:

we know that

The sum of the interior angles of a regular dodecagon is equal to

$S=(n-2)*180$

where

n is the number of sides

In this problem

n=12 sides

substitute

$S=(12-2)*180$

$S=1,800\°$

Find the measure of each interior angle

Divide the sum of the interior angles by the number of sides

$1,800\°/12=150\°$

The measure of the angle formed by the radius and the side of a regular dodecagon is half the measure of the interior angle

therefore

$150\°/2=75\°$

Factor completely 4u^2-28u+49

icang [17]

$\bold{Answer}$

$\boxed{\bold{\left(2u-7\right)^2}}$

$\bold{Explanation}$

$\bold{Factor: \ 4u^2-28u+49}$

$\bold{---------------------}$

$\bold{Rewrite \ 4u^2-28u+49: \ \left(2u\right)^2-2\cdot \:2u\cdot \:7+7^2}$

$\bold{\left(2u\right)^2-2\cdot \:2u\cdot \:7+7^2}$

$\bold{Apply \ Perfect \ Square \ Formula \ \left(a-b\right)^2=a^2-2ab+b^2: \ a=2u,\:b=7}$

$\bold{\left(2u-7\right)^2}$

$\boxed{\bold{Eclipsed}}$

33% of what number is 1.45

MAVERICK [17]

33% of 4.3939 is 1.45

Convert your percentage into a decimal:
$\frac{33}{100} = 0.33$

Divide both of your decimals:
$1.45 \div 0.33 = 4.3939$

Mis Meyer's paid $3600 all together for the equipment, furniture and decorations for her restaurant. The equipment cost $500 mor

Tju [1.3M]

Answer:

The equipment will cost $1740.

Step-by-step explanation:

Let the Cost of equipment, furniture and decoration be x, y and z.

Now, According to question,

x + y + z = 3600 ...... (1) (cost of all items)

x = 500 + y (∵ equipment cost 500 more than furniture)

and y = 2z ( ∵ furniture twice as much as decoration)

so, z = y/2

Now substituting the value of x and z in eq (1)

$x + y + z = 3600$

$500 + y + y + \frac{y}{2} = 3600$

$2y + \frac{y}{2} = 3600 - 500$

$\frac{5y}{2} = 3100$

$y = \frac{3100\times 2}{5} = 1240$

So, the cost of furniture (y) = 1240

∴ Cost of equipment = y + 500 = 1240 + 500 = 1740

Therefore the cost of equipment was $1740.
