How can I improve my math? How can I get better grades and scores in competitions like AMC 8, 10, 12, and MATHCOUNTS? I get low

scores and it's really annoying. I've taken so many, I'm starting to feel mad at myself and feel stupid and dumb. How can I make sure I don't get bad grades?

The length between the bases on a Major League Baseball diamond is 90 feet. Allyson wants to make a scale drawing of a baseball
Vinil7 [7]

Answer:

\text{The scale is }\frac{1}{432}

Step-by-step explanation:

Length between the bases on a major league diamond = 90 feet

1 feet = 12 inches

90 feet = 90 × 12

             = 1080 inches

Length between the bases on a major league baseball diamond on scale drawing = 2.5 inches

\text{Scale factor = }\frac{\text{Actual length}}{\text{Scale length}}\\\\\text{Scale factor = }\frac{1080}{2.5}=432

\text{Hence, the scale is }\frac{1}{432}

Morty buys and sells computer parts
mart [117]

Answer:

  • <em>1. Morty's total cost for the items he purchased was </em><u><em>$210</em></u>
  • <em>2. Morty's revenue from the sale of the items was </em><u><em>$547</em></u>
  • <em>3. Morty's Total profit was </em><u><em>$337</em></u>

<em />

Explanation:

The complete question is:

<em>Morty buys and sells computer parts. He bought two monitors for $25 each and later sold them for $88 each. He bought four cases for $15 each and later sold them for $24 each. He bought five memory modules for $20 each and later sold them for $55 each.</em>

<em />

  • <em>Morty's total cost for the items he purchased was</em>
  • <em>Morty's revenue from the sale of the items was</em>
  • <em>Morty's Total profit was </em>

<em />

<h2><em>Solution</em></h2>

<em />

<u><em>1. Morty's total cost for the items he purchased was</em></u>

<em />

Build a table with the number of parts and their costs:

Component         Amout    Unit cost  Total cost

                                               $                 $

Monitors                2             25                50

Cases                     4             15                 60

Memory                  5             20               100

Total cost = $50 + $60 + $100 = $210

<u><em>2. Morty's revenue from the sale of the items was</em></u>

<em />

Build a table with the number of parts and their selling prices:

Component         Amout    Unit price  Total cost

                                               $                 $

Monitors                2              88               176

Cases                     4              24                96

Memory                  5             55              275

Total revenue: $176 + $96 + $275 = $547

<u><em>3. Morty's Total profit was </em></u>

<em />

The total profit is the total revenue less the total cost: $547 - $210 = $337.

What are the steps to solve for: 1/5(x+5)=1/4(x-3)+1
andrew11 [14]
Step 1. Simplify \frac{1}{5} (x+5) to \frac{x+5}{5}

\frac{x+5}{5} = \frac{1}{4} (x-3)+1

Step 2. Simplify \frac{x+5}{5} to 1+ \frac{x}{5}

1+ \frac{x}{5} = \frac{1}{4} (x-3)+1

Step 3. Simplify \frac{1}{4} (x-3) to \frac{x-3}{4}

1+ \frac{x}{5} = \frac{x-3}{4} +1

Step 4. Cancel 1 on both sides

\frac{x}{5} = \frac{x-3}{4}

Step 5. Multiply both sides by 20 (the LCM of 5,4)

4x=5(x-3)

Step 6. Expand

4x=5x-15

Step 7. Subtract 5x from both sides

4x-5x=-15

Step 8. Simplify 4x-5x to -x

-x=-15

Step 9. Multiply both sides by -1

x=15

Done! :) Hope this helps! :)
