Answer:
3n/8 ≤ 13
Step-by-step explanation:
Answer:
side 1=5x^2+103x+40
side2=5x^3-43+100
side 3=A {let}
we have
perimeter of triangle=side 1+ side2 +side3
5x^4+5x^3+5x^2+50x+100=5x^2+103x+40+5x^3-
43+100+A
A=5x⁴+5x³+5x²+50x+100-5x³-5x²-103x-97
A=5x⁴-53x+3 is your answer
Sallie has $115 which is not enough to buy the skateboard as it costs $119.22
Step-by-step explanation:
Given,
Regular price of skateboard = $137.99
Discount = 20% = 
The discounted sale price of the skateboard without tax can be found by multiplying the regular price by <u>0.2</u>
Discount = 137.99*0.2 = $27.60
Discounted sale price = Regular price - discount

Sales tax = 8% = 
The total amount of sales tax can be found by multiplying the discounted sale price by <u>0.08</u>
Total cost with sales tax = 110.39*0.08 = $8.83
Total cost of skateboard = Discounted sale price + sales tax
Total cost of skateboard = 
Sallie has $115 which is not enough to buy the skateboard as it costs $119.22

Area of lane=area of rectangle
=180x5=900m²
Area of brick=0.2x0. 15
=0.03m²
No of bricks needed=900/0.03
=30000
Cost of bricks=30000/1000x750
=30x750=22500
