Answer:

The temperature at 9 am = -14.7°F

Between 9am and 12 pm = -14.7 + 17.8 = 3.1°F

Between 12pm and 3 pm = 3.1+5.1 = 8.2°

Between 3pm and 6 pm = 8.2-14.5 = -6.3°F

Find 4 consecutive even integers such that the sum of the first and three times the fourth is equal to 48 more than the sum of 2
serious [3.7K]

Answer:

18 , 20 , 22 and 24.

Step-by-step explanation:

Let the numbers be n , n + 2, n + 4 and n + 6.

So we have the following equation:

n + 3(n + 6) =  48 + n + 2 + n + 4

n + 3n + 18 = 48 + 2n + 6

4n + 18 = 2n + 54

2n = 36

n = 18

So the numbers are 18 , 20 , 22 and 24.

Kayleen has been offered two jobs. The first job offers and annual salary of $32000. The second job offers an annual salary of $
xz_007 [3.2K]

Answer:

The amount of money he makes in sale to earn enough commission is $22,000 .

Step-by-step explanation:

Given as :

The salary offered for the first job = $32000 annually

The salary offered for the second job = $10,000 annually + 8% per sales commission

Now, let the number of sale make by Kayleen to earn commission to make more money at second job = n sales

Now, According to question

The salary offered for the first job = The salary offered for the second job + 8% of number of sales

Or, $32,000 = $10,000 + 8% of n

Or, $32,000 - $10,000 = \frac{8}{100}×n

Or, $22,000 = 0.08×n

∴  n = \frac{22,000}{0.08}

I.e n = 275,000

So, The amount of money he makes in sale to earn enough commission =  8% of n

I,e The amount of money he makes in sale to earn enough commission =  0.08×275,000

Or,  The amount of money he makes in sale to earn enough commission =  $22,000

Hence, The amount of money he makes in sale to earn enough commission is $22,000 . Answer

tekilochka [14]

9514 1404 393

Answer:

  5 cm

Step-by-step explanation:

The given arcs have the ratio ...

  BRA : BSA = (3/2) : 1 = 3 : 2

Then BRA is 3/(3+2) = 0.6 of the total circumference of the circle.

  0.6(2πr) = 6π . . . . . BRA is 6π long

  r = 6π/(1.2π) . . . . . . divide by the coefficient of r

  r = 5 . . . . centimeters
