A or B Is the answer I hoped this eliminated your choices a little<span />
49.5
To figure this out you have to multiply the percent times the number but remember to change the percent when multiplying by moving the decimal two places to the right. There fore the equation would be .88•56.25=49.5
Answer:
M
Step-by-step explanation:
We have been given side AB and BC
AB must be 6 as it is between 4 and -2 and that distance is 6 (we have been given no units).
BC must be also 6 as it starts at -4 and ends at 2.
Pythagoras Theorem = a^2 + b^2 = c^2 (^2 means squared)
C is the hypotenuse (longest side) and this is what we are trying to find...
6^2 + 6^2 = 36+36=72
So AC is 72, however we need to square root this to get our final answer.
72 doesn't square easily, so we will use surds. 72 is 36*2 and 36 is a square number hence why...
AC is 6 root 2
Hope this helps!
Answer:
(5,4)
Step-by-step explanation:
thanks to the second information we know that a certain second point of the line is (-1,0)
Now we can use a formula to find the equation of the line, that is
(y-y1)/(y2-y1) = (x-x1)/(x2-x1) where x and y 1 and 2 are the coordinates of the points.
(y+2)/2 = (x+4)/(-1+4)
y+2/2 = (x+4)/ 3
3y+6 = 2x+8
2x-3y+2 = 0
now we have to find the point that make true the equation (we have to sobstitute x and y with the coordinates of the given points)
1) -12 +15 + 2 = 0 ; 3 = 0 (wrong)
2) 6-4+2 = 0 ; 4 = 0 (wrong)
3) 8-15+2 = 0 ; -5 = 0 (wrong)
4) 10-12+2 = 0 ; 0=0 (true)
so (5,4) is the correct answer
