erica watch 1/2 of a movie in the morning and she watched some at night and by the end of the day she still had 1/3 of left how

Anastaziya [24]

Convert to equivalent fractions to see
Both bottom s can be 6
So times the half by 3
And times the third by 2
1/2=3/6
1/3=2/6
So she has a total of 5/6 of the movie accounted for...
So the left over is 1/6
1/6 at nighttime

Just #35 please piecewise functions

saveliy_v [14]

Answer: No, the friend is correct. In any function, each input value can only lead to one output value. When you input 3 for the x-values, you would get two output values because 3 is included in both equations. To fix this, you need to have the 3 not included in one of the equations.

For example, you could say $y=\left \{ {{2x-2, x\leq 3} \atop {-3, x > 3}} \right.$ or $y=\left \{ {{2x-2, x < 3} \atop {-3, x\geq 3}} \right.$ because the input value of 3 would not be included twice.

If you look at the attached screenshot, you will see that if you keep your friend's function, inputting 3 will result in two outputs of 4 and -3, so therefore, $y=\left \{ {{2x-2,x\leq 3} \atop {-3,x\geq 3}} \right.$ cannot represent a piecewise function.

A quadrilaterals consecutive angles measure (3x+10), (9x+50), (4x), and (13x+10). Determine the value of x.

LuckyWell [14K]

The value of x is 10

Step-by-step explanation:

We know that the sum of internal angles of a quadrilateral is 360 degrees

So,

Given

Angle 1 = A1 = 3x+10

Angle 2 = A2 = 9x+50

Angle 3 = A3 = 4x

Angle 4 = A4 = 13x+10

So,

$A_1+A_2+A_3+A_4 = 360\\(3x+10)+(9x+50)+(4x)+(13x+10) = 360\\3x+10+9x+50+4x+13x+10 = 360\\3x+9x+4x+13x+10+50+10 = 360\\29x+70 = 360$

Subtracting 70 from both sides

$29x+70-70 = 360-70\\29x = 290$

Dividing both sides by 29

$\frac{29x}{29} = \frac{290}{29}\\x = 10$

Hence,

The value of x is 10

Brenna ran a total of 8 miles over the course of 4 track practices. How many track practices would it take for Brenna to run 16

solong [7]

Answer:

8 in total

Step-by-step explanation:

8 miles in 4 track practices, that's 2 miles every practice, you just multiply or add. She needs 4 more track practices because 8 x 2 is 16, which is how many miles she runs every practice. If you put 4 more practices it would be 16 miles and 8 practices in total. Sorry if this didn't make sense or confused you, I'm not the best at explaining but you're answer for the total amount of practices is 8.
