How can conversion of measurements help me solve real world problems
jeka57 [31]
In different parts of the world people use different units. Being able to convert will help me understand and fit into their surroundings. Like for instance in Canada people measure speed in kilometers, so their speed limits are written in kmph. While in America the speed is measured in miles so Mph. Knowinf=g the conversions can help you drive safely and not get a ticket.
Hope that was what you were expecting.

I need help on this one someone help me please ​
WARRIOR [948]
I believe the answer is 3. Because if you have a ratio that is 2:1 and Evan has 6 then it would be 6:x and so you just divide two? I hope that is correct! :)

Help me please i’m struggling, u don’t have to explain

<h3>Answer:  10 cm  (choice A)</h3>

====================================================

Explanation:

One equation we could solve is

x/2.5 = 30/7.5

Note the x/2.5 has us dividing the vertical sides, while 30/7.5 is the same idea for the horizontal sides. The order is large over small. You could do small over large, but make sure you keep both sides consistent.

Solving for x leads to...

x/2.5 = 30/7.5

x*7.5 = 2.5*30

7.5x = 75

x = 75/7.5

x = 10  (choice A)

There are many other possible equations that lead to the same answer. One other possible equation is x/30 = 2.5/7.5

These proportions are possible due to the fact we have similar triangles.

Can you fill in the missing words?

The inverse functions of sine, cos and tan functions are csc, sec and cot respectively.

<u>Step-by-step explanation:</u>

The reciprocals of sine, cos and tan functions are csc, sec and cot functions. The reciprocal of cosine function is secant, (sec)  sec θ = $\frac{1}{cos \theta}

The inverse or reciprocal function is cosecant (csc), $ csc \theta = \frac{1}{sin\theta}

The inverse tangent function is cotangent (cot) , expressed in two ways: $ cot\theta = \frac{1}{tan\theta}   or $ cot\theta = \frac{cos\theta}{sin \theta}

So $ tan\theta = \frac{sin \theta}{cos \theta} then its reciprocal or inverse is termed as cot θ.
