Anwser
D) 160
Step by step explanation
To find the area of a object you must multiply the length by the height in this case they gave you an equation instead of an exact height so the first thing you have to do is:
20m x 16m = 320m
But as you can see, all of the answers have an exponent of two meaning we would have to divide 320 by 2
320 ÷ 2 = 160

Answer:
try 55+ 12.5x=210
Step-by-step explanation:
because x needs to be how many visits he needs
1/5 is equal to 0.2, which is also equal to 20%
Answer:
123.75 g
Step-by-step explanation:
You have three unknowns: protein (p), carbohydrate (c), and fat (f)
You need three equations for the three unknowns. They are
(1) p + c + f = 725
(2) 4p + 4c + 9f = 3500
(3) 4p + 9f = 0.45(3500) = 1575
Subtract (3) from (2)
4c = 1925
(4) c = 481.25
Substitute (4) into (1)
p + 481.25 + f = 725
(5) p + f = 243.75
Multiply (5) by 4
(6) 4p + 4f = 975
Subtract (6) from (3)
5f = 600
(7) f = 120
Substitute (7) into (3)
4p + 1080 = 1575
4p = 495
p = 123.75
The diet will include 123.75 g of protein.
