Answer:
4600
Step-by-step explanation:
Standard Form: 4.6
Let T = cost of a taco
Let S = cost of a salad
(2 tacos + 1 salad) + (8 % of 2 tacos and 1 salad) + 3 = 13.80
2T + S + .08(2T + S) + 3 = 13.80
2T + 2.5 + .08(2T + 2.5) + 3 = 13.80
2T + 2.5 + .16T + .20 + 3 = 13.80
2.16T + 5.7 = 13.80
2.16T = 8.10
T = 8.10/2.16 = $3.75
Check: 2T + S + .08(2T + S) + 3 = 13.80
2(3.75) + 2.50 + .08(2(3.75)+2.5) + 3 = 13.80
7.5 + 2.5 + .08(10) + 3 = 13.8
13.80 = 13.80

Answer:
6.25π cm²
Step-by-step explanation:
pi = π
Circumference = 5πcm
Now first we should find radius(r)
2πr = 5π cm
pie will be cancelled and we get here
r = 5/ 2 cm
Therefore r = 2.5 cm
Now
Area (A) = πr²
= π * 2.5²
= 6.25π cm²
22x36= ?ft
? divided by 300 if it isn't exact round down to the nearest whole number... after you do that how ever many times 300 went into ? times that by $3 and there's your answer
Hope i helped ;)
