A parallelogram should be his answer.
47+ 30 is 77 so def is 77 and 103 is deg. and
$50×.20=$10.00=40
$40×.10= 4.00
$40-4.00= $36.00 is the cost of the sweater and he received $14 in savings
Parallelogram.
Opposite sides are parallel.
in a rhombus and square all sides are equal so it isn't those.
It isn't a rectangle either because in a rectangle all angles are ninety degrees
Answer:
- a) NTRD standard price = $26.30
- b) range: $11.20 to $33.00, a range of $21.80
Step-by-step explanation:
a) The average is the sum divided by the number of contributors. Let n represent the standard price at Night-Time Rest Days. Then ...
... ($22.45 +18.55 +24.50 +11.20 +n)/5 = $20.60
... 76.70 + n = 103.00 . . . . multiply by 5 and collect terms
... n = $26.30 . . . . standard price at NTRD
b) The lowest standard price is $11.20. The highest breakfast price is $33.00. The range is the difference between these ...
... $33.00 -11.20 = $21.80 . . . . range in cost for a single night
