The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there

larisa86 [58]

Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.

6cos x-6sin x=3.sqrt6

Yakvenalex [24]

Divide by 6
$cos x - sin x = \frac{\sqrt{6}}{2}$

Square both sides
$cos^2 x -2 sin x cos x + sin^2 x = \frac{3}{2}$

Simplify Left side using Trig identities: (Pythagorean, Double Angle)
$1 - sin (2x) = \frac{3}{2}$

Solve for x:
$sin (2x) = -\frac{1}{2} \\ \\ 2x = \frac{7 \pi}{6}, \frac{11 \pi}{6} \\ \\ x = \frac{7 \pi}{12}, \frac{11 \pi}{12}$
