5/7 of the total amount = 19.60
5/7x = 19.60...with x being the total amount
x = 19.60 * 7/5
x = 137.20 / 5
x = 27.44
Answer: 20 cm
If quadrilaterals WXYZ and BADC are congruent, then their corresponding sides are congruent.
Given that
WX≅DC,
XY≅BC,
you can state that
YZ≅AB,
WZ≅AD.
If AD = 4 cm and AB = 6 cm, then WZ = 4 cm and YZ = 6 cm. Opposite rectangle sides are congruent, then XY = 4 cm and WX = 6 cm.
The perimeter of WXYZ is
P = WX + XY + YZ + WZ = 6 + 4 + 6 + 4 = 20 cm.
Answer:
m= -12
Step-by-step explanation:
-15m-30=-12m+6
-3m=36
m=-12
Answer: Function
f(x) = -2(x-105)^2 +18,050
Step-by-step explanation:
Because only this function satisfies both conditions i.e.
Condition : 1
Profit = 0, when x(items sold) = 10
f(10) = -2(-95)^2 + 18,050 = 0
Condition :2
Profit = 1 , when x = 105
f(105)= -2(105-105)^2 + 18,050 = -2(0) +18,050
f(105) = 18,050.
