Cerrena [4.2K]

This question is based on greatest common multiple.

Answer:

Cynthia is right that Andy made an error.

Step-by-step explanation:

As per Andy, action dvds are = $\frac{3}{5}$

And comedy dvd's are = $\frac{1}{4}$

So, in total these become = $\frac{3}{5}+ \frac{1}{4}$

= $\frac{12+5}{20}$ = $\frac{17}{20}$

This is not 4/9 as per Andy.

Can you help me to find the values of abc and cde ?

Agata [3.3K]

Answer:

88° and 132°

Step-by-step explanation:

The sum of angles in a pentagon ( a 5-sided shape) is given as

= (5 - 2) 180°

= 540°

The angles ∠EAB and ∠AED are supplementary hence the sum is 180° Therefore,

∠AED + 110 = 180

∠AED = 180 - 110

= 70°

Given that the sum of the angles in a pentagon is 540° then

110 + 70 + 2k + 140 + 3k = 540

5k + 320 = 540

5k = 540 - 320

5k = 220

k = 220/5

= 44°

Hence the angle ∠ABC

= 2 × 44

= 88°

∠CDE

= 3 × 44

= 132°

What is the solution of -8 / 2 y - 8 equals 5 / y + 4 - 7 y + 8 / Y 2 - 16

AysviL [449]

Answer:

The value of y is 6.

Step-by-step explanation:

The given equation is

$\dfrac{-8}{2y-8}=\dfrac{5}{y+4}-\dfrac{7y+8}{y^2-16}$

It can be rewritten as

$\dfrac{-8}{2(y-4)}=\dfrac{5}{y+4}+\dfrac{7y+8}{y^2-4^2}$

$\dfrac{-4}{(y-4)}=\dfrac{5}{y+4}+\dfrac{7y+8}{(y+4)(y-4)}$

Multiply both sides by (y+4)(y-4).

$(y+4)(y-4)(\dfrac{-4}{(y-4)})=(y+4)(y-4)(\dfrac{5}{y+4})+(y+4)(y-4)(\dfrac{7y+8}{(y+4)(y-4)})$

$(y+4)(-4)=(y-4)(5)+7y+8$

$-4y-16=5y-20-(7y+8)$

$-4y-16=5y-20-7y-8$

$-4y-16=-2y-28$

$-4y+2y=-28+16$

$-2y=-12$

Divide both sides by -2.

$y=6$

Therefore, the value of y is 6.

Madeline found that the experimental probability of her scoring from a

Eduardwww [97]

Answer:

6 points

Step-by-step explanation:

1/10=x/20
cross multiply the x with the 10 and the 20 with the 1 so that you are now left with the fraction 10x/20
10x divided by 20 will give you x=2
to check and make sure this is still equivalent with the 10% of shots Madeline makes divide 2/20
Since this is still 10 percent Madeline makes 2 out of every 20 shots
Multiply those 2 shots by three points since it was from the three point line and we get 6 points

Hope that helps :)
