Answer:

7 hours with 10 minutes

Step-by-step explanation:

First, find how much minutes it takes to get to 9 a.m, which is 25 minutes.

Then, count up to 3 p.m, which is 6 hours.

Then, add the 45 minutes to 25, which will give you 70, but since you have more than 60 minutes, convert those 60 minutes to an hour adding that up to 7 hours and ten minutes.

Answer:

430 minutes or 7 hours and 10 minutes

Step-by-step explanation:

From 8:35 am to 9 am is 25 minutes. There are 60 minutes in an hour and 9 am to 3 pm is 6 hours. 3:00 to 3:45 pm is an additional 45 minutes.

60 minutes x 6 hours = 360 minutes

360 + 25 + 45 = 430 minutes

What is the solution of the system of equations? {3x−1/2y=−7/2 x+2y=1

k0ka [10]

3x -1/2y = -7/2
x = -2y + 1

3 (-2y + 1) -1/2y = -7/2
-6y +3 -1/2y = -7/2
-13/2y = -13/2
y = 1

x = -2(1) + 1
x = -1

Answer = (-1, 1)

Which is an equation of the line that passes through (–1, –5) and (–3, –7)?

babymother [125]

Answer:

y = x - 4

Step-by-step explanation:

The line passes through (-1,-5) and (-3,-7)

The slope of a line is given by; change in y ÷ change in x

i.e slope = $\frac{-7 - -5}{-3 - -1}$ = $\frac{-2}{-2}$ = 1

Taking another point (x,y) on the line.

Slope will be; $\frac{y - -5}{x - -1}$ = 1

Cross multiplying gives; y + 5 = x + 1

Simplifying this equation gives us the equation of our line which is;

y = x - 4

To find the area of a circle: pir^2.

r=35

pi=3.14

35 times 35=1225

1225 times 3.14=3846.5
