Julie studied for 3 1 3 hours during the 4 days before her last math test. If she studied for the same amount of time each day, how much time did she spend studying each day?

Solution:

Julie studied for 3 \frac{1}{3} hrs in 4 days

Let us first find how many minutes Julie studied in 4 days

In 1 hour, there are 60 minutes

Julie studied for 3 complete hours and one-third of the hour.

So, Number of minutes in 3 hours is 3*60=180hrs

and, Number of minutes in one-third of an hour=\frac{1}{3} *60

=\frac{60}{3}=20minutes

So, time spent by Julie in studying in 4 days is 3\frac{1}{3} hours

or, Julie studied for 180+20 minutes in 4 days

Adding 180 and 20

Julie studied for 200 minutes during the 4 days

To find time she spend studying each day, we must divide total time spent in studies by number of days

Time she spend studying each day= \frac{200}{4} minutes

Dividing 200 by 4, we get

Time she spend studying each day=50 minutes

Answer:

time she spend studying each day=50 minutes

Find the coordinates of point B that lies along the directed line segment from A(-5, 2) to C(11, 0) and partitions the segment i
olga2289 [7]

Answer:

B ( 5 , 3/4 )

Step-by-step explanation:

Solution:-

We are given two points in the cartesian coordinate system as:

                    A ( -5 , 2 )              C ( 11, 0 )

The point B lies on the line segment from A to C. The ratio of segment given is:

                               AB / BC = 5 / 3

To solve such type of problems. We will use vector equation of line AC.

To form a vector equation of line representing AC. We will first determine the direction vector ( d ) that is parallel to the line AC as follows:

                  d = OC - OA

                  d = < 11, 0 > - < -5,2 >

                  d = < 16 , -2 >

The fixed point on the line is taken. We will take point A. The vector equation of line from point A to point C is expressed as:

                 < x , y > = OA + t*d

                 < x , y > = < -5, 2 > + t* < 16 , - 2 >  

The above equation satisfies all the points that lies on the line AC. To determine the coordinates of ( B ). We will plug in the appropriate value of parameter ( t ) and evaluate. We are given the ratio 5:3.

So point B is 5/8 th the magnitude of the distance AC from A. Hence, t = 5/8 as follows:

                < x , y > = < -5 , 2 > + ( 5/8 ) * < 16 , -2 >

                < x , y > = < -5 , 2 > + < 10 , -5/4 >

                < x , y > = < 5 , 3/4 >   ... Answer

Solve for y<br> 4(4y-7) +3y=24
Dima020 [189]

Answer:

y= 52/19 or 2 14/19

Step-by-step explanation:

first we open the brackets

16y-28+3y=24

then we shift the terms

16y+3y= 24+28

19y= 52

y= 52/19 or 2 14/19

hope it helps,pls mark me as brainliest

Helpppppppppppppppppp
harkovskaia [24]

Answer:

Answer choice B

Step-by-step explanation:

When you factor the equation, 12 only has 6x2 to equal the -12x. This means that you'll factor it into (3x-6)(x-2). When you set either of these equal to 0, the x value is 2.
