20 1\4%=81\4%
81\4 x 3
answer=60.75
Answer:
See below.
Step-by-step explanation:
a. 973 * 80
= 973 * 8 * 10
= 7784 * 10
= 77,840.
b. 56 * 2000
= 2*56 * 1000
= 112,000.
c. 5.7 * 300
= 5.7 * 3 * 100
= 17.1 * 100
= 1710.
d. 0.46 * 50
= (0.46 * 100) / 2
= 46 / 2
= 23.
A)
B(-9, 6), D(3, - 2)
slope (BD) = (6+2)/(-9 - 3) = -8/12 = - 2/3
A(-5, -1), C(-1, 5)
slope (AC) = (5+1)/(-1+5) =6/4 = 3/2
b)
d(B,C) = √(-1+9)^2 + (5-6)^2
d(B,C) = √64+1
d(B,C) = √65
d(B,C) = 8.06
answer:
each side is 8.06
Simplify 
, 84 ÷ 12 = 7, so, as a unit fraction equals;
