P=rt+0.16s
365=20r+0.16(1500)
365=20r+240
125=20r
r=6.25
So Piper makes $6.25 an hour.
6000 - 1800 = 4200
4200/4 = 1050
so she donated 25% to charity
Answer:
132600
Step-by-step explanation:
I was always taught like this, and this should be the best estimate:
28 x 4417 --> 30 * 4420 --> 132600
Some other possible estimates with simpler values:
30 * 4400 --> 132000
30 * 4500 --> 135000
30 * 4000 --> 120000
Answer:
y=-2x+15
Step-by-step explanation:
So first we can write it in point slope form.
That is y-y1=m(x-x1)
y1 is the y coordinate
m is the lope
x1 is the x coordinate
This means that the equation is:
y-7=-2(x-4)
We can then convert it to slope intercept form which is
y=mx+b
so
y-7=-2x+8
y=-2x+15
Answer:
25 minutes
If she's going double the speed, it'll take half the time.
