A forest covers 52000 acres. A survey finds that 0.4​% of the forest is​ old-growth trees. How many acres of​ old-growth trees are​ there?

Answers

Given:

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

To find:

The area of old growth trees.

Solution:

We have,

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

Area of old growth trees is

[tex]Area=0.4\% \text{ of total forest area}[/tex]

[tex]Area=\dfrac{0.4}{100}\times 52000[/tex]

[tex]Area=0.4\times 520[/tex]

[tex]Area=208[/tex]

Therefore, the area of old growth trees is 208 acres.

Dena, Barb, Ryan, and Joe played a game where the lowest value wins. Dena's score was 3. Barbs score was -6. Ryan's score was -4. And Joe's score was -2. A) Joe's score beat Dena's score B) Ryan's score beat Barbs score C) Joe had the worst score D) Dena won the game

Answers

A) is the correct answer joe’s score beat dena’s score.

Answer:

A.) Joe's score beat Dena's score

Step-by-step explanation:

When you use negative numbers (Numbers that start with a negative sign (-)), the bigger the number after the negative, the smaller the number and also a negative number is always less than a positive number. This means that Joe's score beats Dena's score, because Joe's score is negative and Dena's score is positive, so Joe's score is lesser than Dena's score.

The owner of a garden center pays $12 for each birdbath. She sells them for 55% more than she paid.

Answers

Answer:

[tex]Selling\ Price = 12b(1.55)[/tex]

Step-by-step explanation:

Given

[tex]Cost\ Price = \$12[/tex]

[tex]Selling\ Price = 55\%\ more[/tex]

Required

Write an expression for the selling price for b birdbaths

This selling price for 1 birdbath is calculated as:

[tex]Selling\ Price = Cost\ Price + 55\% * Cost\ Price[/tex]

Substitute 12 for Cost Price

[tex]Selling\ Price = 12 + 55\% * 12[/tex]

Factorize:

[tex]Selling\ Price = 12(1 + 55\%)[/tex]

Express percentage as decimal

[tex]Selling\ Price = 12(1 + 0.55)[/tex]

[tex]Selling\ Price = 12(1.55)[/tex]

For b birdbaths, the selling price is:

[tex]Selling\ Price = 12(1.55) * b[/tex]

[tex]Selling\ Price = 12b(1.55)[/tex]

The options are not clear; However [tex]12b(1.55)[/tex] answers the question.
