Answer:
B
Step-by-step explanation:
Length of the cube = 7
Working:
Cube root of 343 =7
(or)
7^3=7*7*7=343
Answer:
angle P = 130 degrees
arc SF = 50 degrees
Step-by-step explanation:
angle P = 130 degrees because it is alternate adjacent to 130 degrees.
130 = 1/2(210+SF)
130 = 105+1/2SF
1/2SF = 25
arc SF = 50 degrees
The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.
To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept
