First multiply 3 x 17.50 = 52.50
divide 17.50 in half = 8.75
add those together 61.25
1 gallon 19.00 ( add the previous total ) 80.25
3 divided 4 x 19 = 14.25
add those together and your total answer is 94.5

The number of windows on each floor form an arithmetic sequence; 124 windows on the first floor, 116 windows on the second floor
zubka84 [21]

Answer:

Formula is 132 - 8n, and there are 52 windows on 10th floor.

Step-by-step explanation:

difference = 116-124 = -8  ( 8 less windows for every floor you go up)

the first fllor has 124 windows

Formula:

a_{1} = 124

a_{n} = 124 + (-8)(n - 1) = 132 - 8n

10th Floor:

a_{10} = 124 + (-8)(10 - 1) = 124 + (-8)(9) = 124 - 72 = 52  windows

(trom Unit 4, Lesson 11)

Answer:

The number of kids NOT wearing socks in the gym = 20

Step-by-step explanation:

Here, the total number of kids in the gym = 80

Now, 75% of the kids are wearing socks.

Let us assume the number of kids wearing socks  = m

⇒ 75 % of 80 = m

Calculating the value of m ,we get:

\frac{75}{100}  \times 80 = m\\\implies  m = 60

⇒ 60 kids are wearing socks.

Kids not wearing socks = Total kids in gym - Kids wearing socks

= 80 - 60 = 20

Hence, the number of kids NOT wearing socks in the gym = 60.
