1. 624 students

If you multiply .24 (24%) by 2600, you'll find that the answer is 624.

2. 11% increase in protein

Divide 48 by 54 (48 ÷ 54), you'll notice the answer is around 0.88888. Next subtract 0.88888 by 1. The answer will be around 0.11111.

3. 44% sale

Divide 200 by 360 (200 ÷ 360). The answer will be around 0.5555555556. Next, subtract this number from 1. THIS answer is equal around 0.4444444.

4. 9 players were NOT eligible

Multiply 60 by 0.85 (85%). The answer to this is 51. Subtract 51 from the original number (60). The answer is 9.

5. 420 students plan to go to college

Multiply 1200 by 0.35 (35%). The answer to this is 420.

6. 20% don't have an Instagram account

To make this easier, we'll double to statistics (instead of 4 out of 5, it's 8 out of 10). 8 divided by 10 = 0.8. Subtract 0.8 from 1. Now, you have you're answer: 0.2 or 20%.

I hope this helps! Sorry if some were incorrect. :)

Help me please find x for this triangle!!!!
Ne4ueva [31]

Answer:

x=30

Step-by-step explanation:

Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.

Hope this helped!

I do t know how to do it
Luba_88 [7]

We know: the sum of the angles measures in a triangle is 180°.

Therefore we have the equation:

64° + 75° + α = 180°

139° + α = 180°      <em> subtract 139° from both sides</em>

α = 41°

α and ∠2 are Supplementary Angles - they add up to 180°.

α + m∠2 = 180°

41° + m∠2 = 180°    <em>subtract 41° from both sides</em>

<h3>m∠2 = 139°</h3>
