Answer:
$8.90
Step-by-step explanation:
$2 for the 1/4 mile. That leaves 5 3/4 more miles until 6 miles. He charges 30 cents for each additional 1/4 miles, and there are twenty-three 1/4ths in 5 3/4. So, 23*30=690, which is basically $6.90 because it's 690 cents.
$6.90+$2=$8.90
Answer: <span>y - 37.5 = 2.5 ( x - 7)
Explanation:
1) The point-slope form is has this form:
y - y1 = m (x - x1)
Where m is the slope or rate of change and x1, y1 are the coordinates of the point.
2) you are told that the the rate of change of water (m) is 2.5
m = 2.5
3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:
x1 = 7
y1 = 37.5
</span>4) Replace those value in the point-slope model:
y - 37.5 = 2.5 ( x - 7)
That is the point-slope model or equation.
Just relax, breathe deeply from the diaphragm, allow the
cleansing air to fill your brain, and take it one step at a time.
You said that <u>3t - 7 = 5t
</u>OK. Fine.
Let's just find out what <em>6t</em> is.
Subtract 3t from each side: -7 = 2t
Multiply each side by 3 : <em>-21 = 6t
</em>Did I go too fast for you ?<em>
</em>
The slope is -½, and the y intercept would be (0, -5/2)
Answer:
Percentage of error by Clare is estimated as 4.1667 %.
Step-by-step explanation:
Height measured by Clare = 4 feet
Height measured by Doctor = 4 feet, 2 inches
Percentage error = ?
Percentage error = Difference/ Actual height *100
Percentage error = (2/ (4*12))*100
Percentage error = 4.1667 %
The accurate height is measured by Doctor, as he have more accurate measurement system.
