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?
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.

A typical airplane flies at an altitude of 38,000 feet. Part A: Write an integer to represent an airplane's altitude.
Answer:
+ 38,000
Step-by-step explanation:
Given that:
Altitude of airplane = 38,000
The altitude of an object such as airplane in this scenario refers to the height of the airplane above sea level. The sea level is represented as a zero point (mid level) such that distance below are negative and those above are positive.
Hence, at an altitude of 38000 feets, altitude of airplane can be represented as +38,000 feets.

Step-by-step explanation:
See comment for correct presentation of the question
Given
[tex]Expression = 40\% * 75[/tex]
[tex]Priya = \frac{2}{5} * 75[/tex]
Required
Is Priya correct?
We start by simplifying the expression.
[tex]Expression = 40\% * 75[/tex]
Express 40% as fraction
[tex]Expression = \frac{40}{100} * 75[/tex]
Simplify fraction: Divide numerator and denominator by 20
[tex]Expression = \frac{40/20}{100/20} * 75[/tex]
[tex]Expression = \frac{2}{5} * 75[/tex]
By comparing:
[tex]Expression = \frac{2}{5} * 75[/tex]
and
[tex]Priya = \frac{2}{5} * 75[/tex]
We can conclude that Priya is correct because:
[tex]40\% = \frac{2}{5}[/tex]

Solve for X
1) 8(1 + 5x) + 5 = 13 + 5x
Answer:
X=0
Step-by-step explanation:
[tex]8(1 \times 5x) + 5 = 13 + 5x \\ 8 + 40x + 5 = 13 + 5x \\ 40x + 13 = 13 + 5x \\ 40x - 5x = 13 - 13 \\ 35x = 0 \\ x = 35 \times 0 \\ x = 0[/tex]
The solution to the equation is x = 0.
Here, we have,
Let's solve the equation step by step:
Distribute the 8 to the terms inside the parentheses:
8 + 40x + 5 = 13 + 5x
Combine like terms on both sides of the equation:
40x + 13 = 5x + 13
Subtract 5x from both sides to isolate the variable terms on one side:
40x - 5x + 13 = 5x - 5x + 13
Simplifying:
35x + 13 = 13
Subtract 13 from both sides to isolate the variable term:
35x + 13 - 13 = 13 - 13
Simplifying:
35x = 0
Divide both sides of the equation by 35 to solve for x:
35x/35 = 0/35
Simplifying:
x = 0
Therefore, the solution to the equation is x = 0.

Answer:
Multiply the second equation by 2
Solution: [tex](-\frac{45}{11},\frac{29}{11})[/tex]
Step-by-step explanation:
1) In order to use the elimination method to solve systems of equations, you must first multiply one or both of the equations so that the coefficients of a pair of terms with matching variables share the same number, but have opposite signs.
In this case, the y terms must fit that requirement. The y term in the first equation is 2y and the one in the second equation is -y. They already have opposite signs, one positive and other negative, so we just need -y to be -2y. So, in order to do that, multiply by 2.
2) After multiplying the whole second equation by 2, you will get [tex]8x - 2y = -38[/tex]. Now, add the the two equations together, eliminate the y terms, and isolate x to find its value.
3) Then, substitute that x value back into one of the equations to receive the y-value.
To better explain these steps, I attached pictures below.

At Taco Bell, I made a large purchase of 13 items that cost a total of $28.17. If Chicken Burritos cost $1.89 each and a Cheesy Gordita Crunch costs $2.49, determine how many of each that I purchased.
Answer:
Number of Chicken Burritos purchased=7
Number of Cheesy Gordita Crunch purchased=6
Step-by-step explanation:
Let x be the number of Chicken Burritos and y be the number of Cheesy Gordita Crunch.
Total number items purchased=13
Total cost of 13 items=$28.17
Cost of each Chicken Burritos=$1.89
Cost of each Cheesy Gordita Crunch=$2.49
We have to find number of each items purchased.
According to question
[tex]x+y=13[/tex].....(1)
[tex]1.89x+2.49y=28.17[/tex]...(2)
Equation (1) multiply by 2.49 and then subtract equation (2) from (1)
[tex]0.6x=4.2[/tex]
[tex]x=\frac{4.2}{0.6}[/tex]
x=7
Substitute x=7 in equation (1)
[tex]7+y=13[/tex]
[tex]y=13-7=6[/tex]
Number of Chicken Burritos purchased=7
Number of Cheesy Gordita Crunch purchased=6

Step-by-step explanation:
Using Trigonometry,
tan33° = Opposite/Adjacent = GF/DF.
Therefore GF = DF * tan33°
= 235tan33° = 152.6.
Angle GEF = Angle EDG + Angle DGE
= 33° + 34° = 67°. (Exterior Angle Theorem)
Using Trigonometry,
sin67° = Opposite/Hypotenuse = GF/EF.
Therefore EF = GF / sin67°
= 152.6 / sin67° = 165.8.
Hence the answer is the 1st option.
Answer:
the answer is A. GF =152.6 and EG=165.8
GF= 235*(tan(33))
EG= 152.6/(sin(67))
