Answer:

Step-by-step explanation:

Both of the triangles are special 30-60-90 triangles

and the side lenghts for these angle mesurements are followed : q, q√(3),2q

q is given as 3 from the 9th question

so a = 6 (because it's 2q) and

b = 3

For the 10th question

the side length that sees 30 degrees is 3 which means q = 3 again

and x = 6

y = 3√(3)

Put these in order below are exactly divisible by 9?<br><br> 119 702 432 641 372

KiRa [710]

119 ÷ 9 = 13 2/9
702 ÷ 9 = 78
432 ÷ 9 = 48
641 ÷ 9 = 71 2/9
372 ÷ 9 = 41 3/9 ⇒ 41 1/3

702 and 432 are divisible by 9. The rest are not.

$\huge\bigstar\:$ $\Huge\tt\underline\red{EXPLAINATION}$

The base of the cylinder = 5000 sq.cm

Height = 14cm

The volume of the cylinder = 5000× 14 = 7000

Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 3 inches, and the larger gear has a ra

vaieri [72.5K]

Let r represent the radius of the smaller circle and R the radius of the larger
circle.

Apply ratios: the radius of the smaller circle to the radius of the larger circle.

r: R = 3 : 7.

I complete rotation = 360 degrees.

1st:

For one complete rotation of the smaller circle, the larger circle is rotated through (3/7)*(360) = 154.3 degrees

2nd:For one complete rotation of the larger circle, the larger circle is rotated through (7/3)*(360) = 840.0 degrees

This is equivalent to (840/360) = 2.3 rotations

Alternatively, use the ratios: The number of rotations = R/r = 7/3 = 2.3 rotations

Hope this helped☺☺
