Answer:
For a scientific experiment, a physicist must make sure that the temperature of metal at 0° C gets no colder than -80° C. The physicist changes the metal’s temperature at a steady rate of -4° C per hour. For how long can the physicists change the temperature?
Step-by-step explanation:
y = -x + 5
Slope of this line = - 1.
Slope of the line that is perpendicular is negative reciprocal.
For example if slope= a/b, then slope of the perpendicular line = -b/a.
For our line, the slope is going to be -(-1)=1.
y=mx +b
m=1
y=x+b
We need to find b. We are going to use point (5, -1).
y = x +b
-1 = 5 + b
b= -6
So,
y= x - 6
Answer is A.
Answer:
7 cm
Step-by-step explanation:
Volume of cuboid = L x L x L
42 = 2 x 3 x L
6 L = 42
L = 42/6
L = 7 cm
Each avocado costs 4.98/6, which is .83. 83 cents for one avocado!
This has brightened my day.
