Answer:
The number of big pictures are 49 and number of small pictures are 48 .
Step-by-step explanation:
Let us assume that the number of big pictures are x .
Let us assume that the number of small pictures are y .
As given
Big pictures are 56$ each small ones are 34$.
97 were sold at the total of $4,376.
Equations becomes
x + y = 97
56x + 34y = 4376
Multiply x + y = 97 by 56 and subtracted from 56x + 34y = 4376 .
56x - 56x + 34y - 56y = 4376 - 5432
-22y = - 1056
22y = 1056
y = 48
Put value of y in the equation x + y = 97
x + 48 =97
x = 97 - 48
x = 49
Therefore the number of big pictures are 49 and number of small pictures are 48 .
Perimeter of the triangle ABC is 18.7 units.
Coordinate of the point A is (4, -1), B is (-1, 4) and C is (0, -3).
Length of the side AB = 
AB = 
AB = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side BC =
BC = 
BC = 
BC = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side CA =
CA = 
CA = 
CA = 4.47 units = 4.5 ( rounded to the nearest 10th)
Perimeter of the triangle ABC = sum of all three sides = (7.1 + 7.1 + 4.5) units = 18.7 units
Answer:
55 hours 13 min
55.2166 hours
Step-by-step explanation:
mon - 3 hr 28 min + 3 hr 49 min = 6 hr 77 min --> 7 hr 17 min
tues - 4 hr 22 min + 4 hr 26 min = 8 hr 48 min
wed- 3 hr 39 min + 4 hr 49 min = 7 hr 88 min -->8 hr 28 min
thurs- 9 hr 51 min + 5 hr 30 min = 14 hr 81 min --> 15 hr 21 min
fri- 9 hr 46 min + 5 hr 33 min = 14 hr 79 min --> 15 hr 19 min
total --> 53 hours 133 min
55 hours 13 min
