Answer:
18617.66 ft^2
Step-by-step explanation:
sides of triangular base
a= 145ft ,
b = 257ft ,
c = 290ft
<u>calculate the area of the base </u>
The base is a scalene triangle hence the area is calculated as follows
s = ( a + b + c ) / 2
= ( 145 + 257 + 290 ) / 2 = 346
Area of triangle = 
= 18617.66 ft^2
First you got to multiply 2x7=14x then multiply again 2x3=6 so the answer to the equation will be 2(7x+3)=(14x+6)
The first one is 75% i think I dont know if thats the answer though hold on and I'll get you the others
Answer:
$140
Step-by-step explanation:
Total Amount of chocolate = 100 Pounds
Amount of chocolate in one box = 1 1/4 Pounds = 5/4 Pounds
Number of boxes = 100/(5/4) = 80 boxes
Cost of one box = $1.75
Total selling price = 80×1.75 = 140
The total selling price for all the boxes of chocolate is $140
Answer:
24 ft
Step-by-step explanation:
Hypotenuse = √9²+16²=√81+256=√400=20ft
the upper side of the stuff = 4 ft
total = 20+4=24
