Answer: 1371.57 calories
Step-by-step explanation:
Plug 150 in for m.
Cube it to cancel out the cube root on the right side:
= 3375000
Find its 4th root to cancel out the exponent of 4 on the right side:
= 42.861
Now multiply by 32 to find r:
42.861 * 32 = 1371.57 calories

Answer:
x=92 y=23
Step-by-step explanation:
Let them be x and y respectively
so given
x-y=69
and
x/y=4 x=4y
so we can write
x-y=69
as
4y-y=69 3y=69 y= 69/3 = 23
now y is 23
so putting in any equation will give the value of x
so
x-23=69 x=92
