Answer:

see explanation

Step-by-step explanation:

17

The diagonals of a parallelogram bisect each other, then

x + 6 = 11 ( subtract 6 from both sides )

x = 5

and

y - 7 = 10 ( add 7 to both sides )

y = 17

(18)

The opposite sides of a parallelogram are congruent , then

3a + 11 = a + 15 ( subtract a from both sides )

2a + 11 = 15 ( subtract 11 from both sides )

2a = 4 ( divide both sides by 2 )

a = 2

and

3b + 5 = b + 11 ( subtract b from both sides )

2b + 5 = 11 ( subtract 5 from both sides )

2b = 6 ( divide both sides by 2 )

b = 3

Find the value of X
vredina [299]

Answer:

x=8

RPS = 36

Step-by-step explanation:

QPS = 180

The two angles that form QPS

QPR + RPS = 180

7x+88 + 3x+12 = 180

Combine like terms

10x+100 =180

Subtract 100 from each side

10x = 180-100

10x = 80

Divide by 10

x =80/10

x = 8

RPS = 3x+12

        = 3(8)+12

         24+12

        36

!EASY! A two-story hotel has 20,000 square feet of space on the first floor for rooms and 35,000 square feet of space on the sec
snow_tiger [21]

Answer:

The correct answer is: c) 171

Step-by-step explanation:

In order to find the number of rooms first of all we have to find the area of a single room

Given that the dimensions of room is:

16 ft * 20 ft

The area of a room is: 320 square feet

So

Area for rooms on first floor = 200000 square feet

The number of rooms on first floor will be:

=\frac{20000}{320} = 62.5

As the number of rooms cannot be in decimal and as we are dealing with floor area some area can be spared but no extra area can be added so the floor function will be applied which rounds off the number to previous whole number

Then number of rooms on first floor is 62

And '

Area for rooms on second floor = 35000 square feet

the number of rooms:

=\frac{35000}{320}\\=109.375

Rounding off using floor function

Number of rooms on second floor = 109

Total number of rooms  = 62+109 = 171

Hence,

The correct answer is: c) 171
