Answer:
$1323.00
Step-by-step explanation:
A simple equation that can be used to figure this out is:
p*1.5*o=t
The variables mean:
p- hourly pay
o- hours worked overtime
t- total amount of money earned.
(Also, the 1.5 is always used to calculate overtime, no matter what job, unless otherwise specified, and as referred in the problem as "time and a half").
So, to finally work out this problem:
($14*1.5)*63=?
first, (14*1.5)= $21
($21*63)= $1323.
Answer:
C) 7 and 3
Step-by-step explanation:
2x+4+8x-10=x²+15
10x-6=x²+15
0=x²-10x+21
0=(x-3)(x-7)
x=3 and 7
Answer:
Step-by-step explanation:
Consider the trapezoid ABCD. In this trapezoid BC=a and AD=b.
Since triangles BOC and AOD are somilar, then
Triangles OAE and CAB are similar, then
This means that
Similarly, from similar triangles FDO and CDB:
Thus,
