Answer:
46
Step-by-step explanation:
for perimeter just add up the side
9+14+9+14 or 9+14 = 23 then 23* 2 =46
Answer:
4712.54
Step-by-step explanation:
His total annual premium 4712.54
. Billy received the deducted by $105.73 paycheck, twice a month throughout the year, so he received 24 deducted paychecks in a year. The sum of all the deducted $105.73 amount throughout the year will be the 35% of Billy's total annual health insurance premium.
To get the amount his employer contribute towards his health insurance on an annual basis, we will have to multiply the sum deducted by twice a month throughout the year in which he received deducted paychecks.
105.73 * 24 = 2537.52
The next step is to divide our answer with 35% of Billy's total annual health insurance premium.
x = 2537.52/.35
x = 7250.06
7250.06 * 0.65 = 4712.54
Ellie:
Total spending = $36.50
Number of popcorn bags bought = 7
Number of drinks bought = 2
Morgan:
Total spending = $155.50
Number of popcorn bags bought = 9
Number of drinks bought = 14
Part 1:
If
P = Price of one popcorn bag
D = Price of one drink
Then,
For Ellie: 7P + 2D = 36.50
For Morgan: 9P + 14 D = 155.50
Set of equations:
7P + 2D = 36.5 --------(1)
9P + 14D = 155.5 ---- (2)
Part 2:
Solving equations (1) and (2)
Multiply (1) by 7 and subtract (2) from resulting equation;
49P + 14D = 255.5
9P + 14D = 155.5
-------------------------
40P = 100
P = 100/40 = 2.5
From eqn (1),
7*2.5 + 2D = 36.5
17.5 +2D = 36.5
2D = 19
D = 19/2 = 9.5
Therefore,
Bag of popcorn costs $2.50
A , y= -40x + 300 , ik I’m not going to get the brainliest answer but it was good helping :)
31.35d + 0.15(275) </= 280
Step-by-step explanation:
(Daily cost x number of days) + (mileage cost x number of miles) is less than or equal to $280.
If they ask you to solve it next:
31.35d + 0.15(275) </= 280
31.35d + 41.25 </= 280
31.35d </= 238.75
d </= 7.615629998
Round it down to 7 full days
