Answer:

4:12pm

Step-by-step explanation:

85 minutes = 1 hour and 25 minutes

2:47pm + 1 hour 25 minutes = 3:72 pm

72 minutes = 1 hour 12 minutes so add another 1 hour to 3 and the balance is 12 minutes so walk ends at 4:12pm

Another way to look at it is as follows:
After 13 minutes, the time is 2:47 + 0:13 = 3pm

Remaining time left is 85-13 = 72 minutes = 1 hour: 12 minutes. Add that to 3pm and you get 4:12pm

Line t intersects the line given by y=4x-2 at the point (4,14) to form a right angle. Which is the equation of line t

Aliun [14]

Answer:

y = -1/4 x + 15.

Step-by-step explanation:

y = 4x - 2 has a slope of 4 ( = the coefficient of x).

The line at right angles to it will therefore of a slope of -1/4.

Using the point-slope form of a line the line t which passes through (4, 14) is found as follows:

y - 14 = -1/4(x - 4)

y = -1/4x + 1 + 14

y = -1/4x + 15

FIRST ONE TO ANSWER RIGHT AND EXPLAIN HOW THEY GOT THAT ANSWER WILL BE MARK BRAINIEST

Vikentia [17]

Answer: The percent error=16%

Step-by-step explanation:

Estimated amount of liquid in a container = 50 ml

Actual amount of liquid in the container = 43 ml

We know that the percent error = $\frac{|estimated\ value-actual\ value|}{actual\ value}\times100$

By substituting the values in the formula, we get

The percent error= $\frac{|50-43|}{43}\times100$

⇒The percent error= $\frac{7}{43}\times100=0.1627\times100$

⇒The percent error= $16.27\%\ \approx16\%$

∴ The percent error=16%
