Answer:

The answer is 43 and 19 over 21

Step-by-step explanation:

21 goes into 922 43 times. This giving you 903. 43 Will then be your Whole number. You the subtract 922 by 903, this giving you 19. 19 is going to be your numerator. Then you always keep the denomonator which is 21. This giving you 43 and 19 over 21

Answer:

Arc length is $\frac{14\pi}{3}$ , or, 14.7

Step-by-step explanation:

AB is an arc intercepted by 140 degree angle. The formula for length of an arc is given by

$AL=\frac{\theta}{360}*2\pi r$

Where

AL is the arc length

$\theta$ is the angle (in our case, 140)

r is the radius of the circle (which is 6)

Substituting, we get:

$AL=\frac{\theta}{360}*2\pi r\\AL=\frac{140}{360}*2\pi (6)\\AL=\frac{7}{18}*12\pi\\AL=\frac{14\pi}{3}$

In decimal (rounded to tenths) - 14.7

Determine whether the two ratios are proportional. 6/36 and 1/6 a) Yes b) No

Xelga [282]

Yes, they are. Treat ratios like fractions, simplify them the same way. In 6/36, the GCF (Greatest Common Factor) of the numerator and the denominator is six. So, we divide both sides by six. This gives us 1/6, which is still the same fraction. (Making it proportional)

These cylinders are similar. Find the volume of

Basile [38]

Answer:

$V_s=85\ cm^3$

Step-by-step explanation:

Let $V_s\ and\ V_b$ be the volumes of the smaller and bigger cylinder.

The formula for the volume of a cylinder is given by :

$V=\pi r^2 h$

As the two triangles are similar, the cube of their ratio would equal the ratio of their volume i.e.

$\dfrac{V_s}{V_b}=(\dfrac{h_s}{h_b})^3\\\\\dfrac{V_s}{V_b}=(\dfrac{3}{5})^3\\\\\dfrac{V_s}{V_b}=0.216\\\\V_s=393\times 0.216\\\\V_s=84.8\\\\or\\\\V=85\ cm^3$
