In science class, the girl to boy ratio is 3 to 7.

Mariana [72]

Answer:

There are <u>35 boys</u> in the class.

Step-by-step explanation:

Girls to Boys ratio = 3:7

Total number of students in class = 50

Let total number of girls be '3x' and total number of boys be '7x'

Total number of girls + Total number of boys = Total number of students

3x + 7x = 50

10x = 50

x = 50/10

x = 5

$\therefore$

Total number of girls = 3 × 5 = 15

Total number of boys = 7 × 5 = 35

PLEASE ANWSER CORRECTLY!! I WILL MARK BRAINIEST!!!

Answer:

$x = 10°$

$z = 66°$

Step-by-step explanation:

$(9x - 24)° + (12x - 6)° = 180°\\21x° - 30° = 180° \\ 21 x° = 180° + 30° \\ 21x° = 210° \\ x° = \frac{180°}{30°} \\ x° = 10°$

z° = 9x - 24 ( vertically opposite )

z° = 9(10) - 24

z° = 90 - 24

z° = 66°
