How do you use the scale on a scale drawing to find the measurements of actual projects
vampirchik [111]

Answer:

multiply the scale drawings side lengths by the scale

Step-by-step explanation:

for instance, if i have a square shaped scale drawing with the side lengths of 4in, and the scale is 2in, i would multiply 4 by 2, and the actual drawing's side lengths would be 6.

if i did not know the scale and i knew the actual drawings side lengths and the scale drawings side lengths, i would divide the corresponding lengths

example: rectangular scale drawing with the lengths, 5, 5, 10, and 10. and an actual drawing with the lengths 10, 10, 20, and 20. if i divide 20 by 10 or 10 by 5, i'd get 2, the scale

In a class, 60% of the students are boys and the rest are girls. If the number of boys is 30, how many students are there? ​
irga5000 [103]

50 total students

  • 20 girls

Explanation:

total students: 100%

  • 1% → 0.5
  • 100% → (0.5 * 100)
  • 100% → 50

number of girls:

  • total students - number of boys
  • 50 - 30
  • 20

Perform the following calculations without rewriting the numbers in decimal form.
RSB [31]

Answer:

Answer will be 140\times 10^{13}

Step-by-step explanation:

We have to perform the calculation (1.42\times 10^{15}-2\times 10^{13}) without changing into decimal

1.42\times 10^{15} can be written as 142\times 10^{13}

So 1.42\times 10^{15}-2\times 10^{13}=(142\times 10^{13}-2\times 10^{13})

Now taking 10^{13} common

10^{13}(142-23)=140\times 10^{13}
