The airplane has a wingspan of a feet and a tailspan of b feet. If the tailspan in the drawing is 2 inches, and a/b = 3, what is the actual wingspan of the airplane?Scale: 1 inch = 5 feet

Answers

x/2 = 3 (x= 3*2 = 6in)

6in = 30ft

Hope I become the brainliest answer

Answer:

30 feet is correct.

Step-by-step explanation:

Since a = 3b, the wingspan is 6 inches in the drawing, so it is 6x5 = 30 feet on the plane.

36 is 0.9 of what number?

Answers

to solve for x you do these steps
x=number

1. do this following multiplication problem to get 0.9%
36/x*100%= 0.9%

2. now do the opposite of what you did before to get x
36 divided by 0.9%= x

36 divided by 0.9%= 40

x = 40
36 / 0.9 = 40

12. Zac wil spend $185.00, or 5%, of his budget on gasoline. Gas prices have increased, and he needs to adjust his budget. If he needs to increase his gas budget by $78.00 per month.by what percentage must he reduce his other expenses?

Answers

156 but a point in-between 15 and 6

Final answer:

Zac needs to reduce his other expenses by approximately 2.22% to accommodate the increased gas prices while maintaining his total budget.

Explanation:

  • Zac initially budgeted $185.00 for gas, which represents 5% of his overall budget. This means his total budget is $3700.00 (since $185.00 is 5% of $3700.00). With the increase in gas prices, he needs to raise the gas budget by $78.00, bringing the total to $263.00. Now, Zac's gas budget becomes about 7% of his total budget.

Therefore, Zac's other expenses need to be reduced to maintain the same overall budget.

  • Thus, his non-gas budget was originally $3515.00 (i.e., $3700.00 - $185.00) and now needs to be $3437.00 (i.e., $3700.00 - $263.00).
  • The decrease in the non-gas budget is $78.00.
  • The percentage decrease of other expenses is the decrease in non-gas budget divided by the original non-gas budget ($78.00/$3515.00), which is approximately 2.22%.

So Zac needs to reduce his other expenses by about 2.22% to accommodate the increased gas prices.
