Last season the girls' volleyball team had 5 seventh-grade students and 4 sixth-grade students. What is the ratio of sixth-grade
Hoochie [10]

Answer:

A) 4:5

Step-by-step explanation:

A) 4:5

B) 4:9

C) 5:4

D) 5:9

If there are 4 sixth grade students, you can already cross off D because there is no 4 as an option. There are 5 seventh grade students, you can cross off B because there's no 5. So now it's down to 4:5 or 5:4. Since it wants the ration of sixth to seventh, it's 4 to 5.

Hence, the ratio is 4:5, answer A

Hope this helps :)

The discriminant for a quadratic polynomial gives you information about the polynomial's roots.

Given y=ax^2+bx+c, the discriminant is given by \Delta=b^2-4ac.

There are three possible conclusions you can draw. If \Delta>0, then the quadratic has two distinct real roots. If \Delta=0, then there is one repeated real root. If \Delta, then there are two complex (non-real) roots.

Since you found \Delta=72>0, that means that y has two distinct real roots.

Continue each pattern with the next two numbers
RoseWind [281]

Pattern #1:  (I think it should have started with 7, not 17)

7 -> 14     either added 7 or multiplied by 2

14 -> 8     subracted 6

8 -> 16     either added 8 or multplied by 2

16 -> 10    subtracted 6

10 -> 20   added 10 or multiplied by 2.

The pattern seems to be multiply by 2, then subtract 6, repeat.

14 -> 28

28 -> 22

Pattern #2:

11 -> 13     added 2

13 -> 16    added 3

16 -> 20   added 4

20 -> 25  added 5

25 -> 31   added 6

31 -> 38   added 7

to finish...

38 + 8 = 46

46 + 9 = 55

Plz help me <br> I forgot<br> How to solve
sveta [45]

Given:

A cyclic quadrilateral and two opposite angles of it in the form of y.

To find:

The value of y.

Solution:

We know that, opposite angles of a cyclic quadrilateral are supplementary angles. So, their sum is 180^\circ.

The measures of opposite angles of cyclic quadrilateral are y and 2y. So,

y+2y=180^\circ

3y=180^\circ

Divide both sides by 3.

y=\dfrac{180^\circ}{3}

y=60^\circ

Therefore, the value of y is 60^\circ.
