The ratio of boys to girls in a choir is 3 to 6. There are 30 girls in the choir.
agasfer [191]

Answer:

45 members are in the choir.

Step-by-step explanation:

Set up an equation:

Variable x = boys

3/6 = x/30

Cross multiply:

3 × 30 = 6 × x

90 = 6x

Divide both sides by 6:

15 = x

There are 15 boys.

To find the number of members in the choir, add the number of boys and girls:

30 + 15 = 45

Name the intersection of planes ABFE and BFCD.
Mkey [24]

Two planes intersect in a line that contain all common points of these two planes.

1. Plane named ABFE contains points A, B, F and E.

2. Plane named BFCD contains points B, F, C and D.

As you can see points B and F are common points for these two planes, then the line of intersection is BF and its notation is \overleftrightarrow{BF}.

Note that notation \overline{BF} stays for segments and notation \overrightarrow{BF} stays for rays.

Answer: correct choice is A.
