Math Formulas

Math formulas are expressions that have been created after several decades of research that help to solve questions quickly. It is easy to perform simple arithmetic calculations such as addition, subtraction, and so on. However, when it comes to algebraic expressions, geometry, and other topics you need mathematical formulas to simplify the process of reaching the answer and saving time in the process. At Cuemath you will not only find formulas for every topic but will also get an idea of how that equation was developed. Thus, you will not have to memorize formulas, as you understand the concept behind them.

Use these formulas to solve problems creatively and you will automatically see an improvement in your mathematical skills. Given below is the list of formulas alphabetically arranged for your convenience. Hence, you can easily find formulas that need to be revised or require to be referenced.

The links to the list of math formulas available on different topics have been arranged alphabetically for your convenience. So pick a topic and start learning!

Clyde Cement wants to analyze a shipment of bags of cement. He knows the weight of the bags is normally distributed so he can us
avanturin [10]
The percentage of the bags of cement that would weigh less than 50 lbs. would be 50% because the normal distribution is symmetrical, and since the mean is your midpoint, then it would be 50% higher, and 50% lower.

⚡️⚡️Really need help, would appreciate it⚡️⚡️
pentagon [3]

Answer:

The answer to your question is letter A. Regular size is cheaper than Economy size by $0.0003 per gram

Step-by-step explanation:

Cost of 1 gr of economy size

  5000 gr (5 kg) -------------------  $ 5.15

         1 gr            --------------------     X

x = 1 x 5.15 / 5000 = $0.0010

Cost of 1 gr of regular size

  820 gr -------------------   $0.60

       1 gr --------------------   x

x = 1 x 0.6 / 820 = $ 0.0007

Difference of cost  = $0.0010 - $0.0007 = $0.0003
