Paul's rate before the pay rise = 7.0
The increase = 4/100 * 7.0 = 0.28
Paul's rate after the pay rise = 7.0 + .28 = 7.28
Answer: 27.97 m^2
Explanation:
Area = Length x Width
Area = 3.6m x 7.77m
Area = 27.97 m^2
If she went 10 miles upstream in the same time as she went 20 miles downstream, that means the downstream speed is twice the upstream speed.
The speed is still water is 9 mph.
The speed of the current is c.
Going downstream, the current adds speed, so the sped downstream is 9 + c.
The speed upstream is 9 - c.
9 + c is twice 9 - c.
9 + c = 2(9 - c)
9 + c = 18 - 2c
3c = 9
c = 3
Answer: The speed of the current is 3 mph.
Check:
9 + c = 12
9 - c = 6
By taking into the account the speed of the current, the downstream speed, 12 mph, is indeed twice the upstream sped, 6 mph.
Answer: 3.19 feet.
Step-by-step explanation: 319 divided by 100 is 3.19
Let's use the point-slope formula here:
y - 5 = -2(x - 3). That's it. You could, of course, rewrite this in slope-intercept form, as follows:
y = 5 - 2x + 6, or y = -2x + 11, in slope-intercept form.
