Answer:

tan A = -15/8.

Step-by-step explanation:

sin^2a = 1 - cos^2A

= 1 - (-8/17)^2

= 225/289

So sin A= 15/17

tan A = sin A / cos A

=  15/17 / -8/17

= 15/-8

= -15/8.

A snail travels 10 cm in 4 minutes. At this rate: How long will it take the snail to travel 24 cm?
atroni [7]

It will take the snail 9.6 minutes to travel 24cm.

Step-by-step explanation:

Distance covered in 4 minutes = 10 cm

Ratio of distance to time = 10:4

New distance = 24cm

Let,

x be the time period

Ratio of new distance to time = 24:x

Using proportions;

Ratio of distance to time :: Ratio of new distance to time

10:4::24:x

Product of mean = Product of extreme

24*4=10*x\\96=10x\\10x=96

Dividing both sides by 10

\frac{10x}{10}=\frac{96}{10}\\x=9.6\ minutes

It will take the snail 9.6 minutes to travel 24cm.

Anoki bought 360 millimeters of fabric. How many centimeters of fabric does Anoki have? It’s either 360, 36.0,3.60, or 0.360
Stels [109]
Hey!


First, we need to know how many millimeters are in a centimeter.

<em>10 mm = 1 cm</em>

Okay, now we can write an equation.

<em>360 mm ÷ 10</em>

To solve this equation, we simply divide.

<em>360 mm ÷ 10 = 36 cm</em>

<em>So, if </em><span><em>Anoki bought 360 millimeters of fabric, that means he has </em> 36.0 centimeters  <em>of fabric.</em>

Hope this helps!
