MARKING BRAINLIEST TO FIRST PERSON WHO ANSWERS!!! AND ALSO UPPING POINTS TO 25!

Mathematics
1 answer:
Paha777 [63]2 years ago

Answer:

x ≈ 35°

Step-by-step explanation:

Since we don't know the angle, we will replace it with X for now.

Tangent=(\frac{Opposite}{Adjacent})

  • Opposite of X = 12.5 m
  • Adjacent of X = 18 m

tanX = \frac{12.5}{18}

  • Since we are trying to find the angle, we have to subtract "tan\\"

X = tan^-^1(\frac{12.5}{18})

X ≈ 35°

Answer:

7 inches

Step-by-step explanation:

First you have to find the average height of each class.

4th Grade:

56, 47, 54, 51, 53, 58, 48, 54, 46, 53

Then you have add it all up and divide it by how many students there are.

56 + 47 + 54 + 51 + 53 + 58 + 48 + 54 + 46 + 53 = 520

520 ➗10= 52

Same process for the 7th Grade.

You end up getting 52 and 59. You then Subtract it to get the answer to the question.

52 - 59= 7 inches

How to solve 4/7y-2 = 3/7 + 3/14
lisabon 2012 [21]
Solution

1) Simplify \frac{4}{7y}<span> to </span>\frac{4y}{7}
\frac{4y}{7} <span>−2= </span>\frac{3}{7} + \frac{3}{14}

2) Simplify \frac{3}{7} + \frac{3}{14} <span>to <span>914</span>
</span>\frac{4y}{7} <span>−2= </span>\frac{9}{14}

3) <span>Add 2 to both sides
</span>\frac{4y}{7} = \frac{9}{14} <span>+2
</span>
4) Simplify \frac{9}{14&#10;} <span><span>+2</span> to </span>\frac{37}{14}
\frac{4y}{7} = \frac{37}{14}

5) <span>Multiply both sides by 7
</span><span>4y= </span>\frac{37}{14} <span>×7
</span>
6) Simplify \frac{37}{14} <span><span>×7</span> to </span>\frac{259}{14}
\frac{4y}{7} =\frac{259}{14}

7) Simplify \frac{259}{14}<span> to </span>\frac{37}{2}
\frac{4y}{7} = \frac{37}{2}

8) <span>Divide both sides by 4
</span>y= \frac{37}{2} <span>×4
</span>
9) <span>Simplify <span>2×4</span> to 8
</span><span>y=</span>\frac{37}{8}
<span><span>
Hope this helps
