A forest covers 32,000 acres. A survey finds that 0.4% of the forest is old-growth trees. How many
acres of old-growth trees are there?
There are acres of old-growth trees.
PLEASE HELP
Answer:
128.
Step-by-step explanation:
The equation we need is going to be 32,000 multiplied by 0.04% written as a decimal.
Since 0.04% written as a decimal is 0.004, the equation will be:
32000*0.004= ?
32000*0.004= 128.

Which statement is true?
Answer:
Step-by-step explanatmkjion:
The Correct statements is [tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex].
To determine which statement is true, let's evaluate each statement one by one:
[tex]\sqrt[m]{x} * \sqrt[m]{y} = 2\sqrt[m]{xy}[/tex]
This statement is false. The correct product of two nth roots ([tex]\sqrt[m]{x}[/tex] and [tex]\sqrt[m]{y}[/tex]) is [tex]\sqrt[m]{x*y}[/tex], not 2[tex]\sqrt[m]{x*y}[/tex].
[tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex].
This statement is true. When raising an nth root to a power, you can simply multiply the exponents. So, [tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex]..
[tex]a \sqrt[n]{x}+ b \sqrt[n]{x} = ab \sqrt[n]{x}[/tex]
This statement is false. The correct result of adding two nth roots is not the product of the coefficients. It's simply (a + b) [tex]\sqrt[n]{x}[/tex].
[tex]\sqrt[m]{x} /\sqrt[m]{y} = \sqrt[m]{xy}[/tex]
This statement is false. The correct division of two nth roots ([tex]\sqrt[m]{x}[/tex] divided by [tex]\sqrt[m]{y}[/tex]) is not equal to the product of the roots. The correct division is:
[tex]\sqrt[m]{x} /\sqrt[m]{y} = \sqrt[m]{x/y}[/tex]
So, [tex]\sqrt[m]{x} /\sqrt[m]{y}[/tex] is equal to [tex]\sqrt[m]{x/y}[/tex], not [tex]\sqrt[m]{xy}[/tex].
Correct statements:
[tex](\sqrt[m]{x^a})^b = \sqrt[m]{x^{ab}} \\[/tex]

Study this incomplete image of a geometric construction. This image may result from the construction of ____
A. a line parallel to line AB through C.
B. a perpendicular to line AB.
The next step in this construction is to set the compass width to
A. line segment DC and draw an arc centered at D intersecting the second arc.
B. line segment KC and draw an arc centered at K intersecting the second arc.
C. arc IJ and draw an arc centered at K intersecting the second arc.
D. line segment CI and draw an arc centered at I intersecting the second arc.
Thank you.
Answer:
A line parallel to line AB through C & arc IJ and draw an arc centered at K intersecting the second arc
Step-by-step explanation:
This image may result from the construction of a line parallel to line AB through C.
The next step in this construction is to set the compass width to arc IJ and draw an arc centered at K intersecting the second arc.
What is Construction?Geometric constructions are precise drawings of geometrical shapes, angles, and lines. We will need a pencil, a ruler (or other straight edge), and compasses to do this.
Given:
From the image we can see that there is an attempt to make a copy of angle and proceeds to draw a parallel line.
So, This image may result from the construction of a line parallel to line AB through C.
Now, the next step can be measure the arc IJ from compass and put the pointer on K with same measurement and cut the Arc.

What is the solution to a linear equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
Given here: x−2y=−7 & 3x+2y=3
Thus solving these two equations we get -8y=-24 or y=3

Suppose the heights of 18-year-old men are approximately normally distributed, with mean 69 inches and standard deviation 6 inches.What is the probability that an 18-year-old man selected at random is between 68 and 70 inches tall? (Round your answer to four decimal places.)
Answer:
0.1350 = 13.50% probability that an 18-year-old man selected at random is between 68 and 70 inches tall
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 69, \sigma = 6[/tex]
What is the probability that an 18-year-old man selected at random is between 68 and 70 inches tall?
This is the pvalue of Z when X = 70 subtracted by the pvalue of Z when X = 68. So
X = 70
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{70 - 69}{6}[/tex]
[tex]Z = 0.17[/tex]
[tex]Z = 0.17[/tex] has a pvalue of 0.5675
X = 68
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{68 - 69}{6}[/tex]
[tex]Z = -0.17[/tex]
[tex]Z = -0.17[/tex] has a pvalue of 0.4325
0.5675 - 0.4325 = 0.1350
0.1350 = 13.50% probability that an 18-year-old man selected at random is between 68 and 70 inches tall

A mailbox that is 4 1/2 feet tall casts a shadow that is 6 feet long. At the same time, a nearby ferris wheel casts a shadow 84 feet long. Find the height of the ferris wheel.
60 feet
Answer: 63 ft
Step-by-step explanation:
We can think of the shadow and height of objects as the catheti of a triangle rectangle.
We also know the relationship:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
if we define:
Tan(θ) = k (a real number, such that will be the same number for every object, because it depends on the angle θ that will depend on the position of the sun)
opposite cathetis = heigt.
adjacent cathetus = length of the shadow.
Then we have:
k = height/length of the shadow.
For the mailbox, we know that the height is (4 + 1/2) ft and the shadow is 6ft long, then we have the equation:
k = (4 + 1/2)ft/6ft = 0.75
Then for the ferris wheel we know:
shadow length = 84ft
we can write the same equation as above:
k = 0.75 = height/84ft
0.75*84ft = height = 63ft
The ferris wheel is 63 ft high.

63 feet

Answer:
The missing value of x is 3
Step-by-step explanation:
Given Table:
x y
3 10
__ 20
The relation of x and y (x,y) is not a function.
Relation is function if it is one-to-one.
One-to-one means to different value of x to get different value of y.
If function is not a function then one value of x to get two different value of y.
For first value of x=3, y=10
For which value of x= ? , y=20
x must be 3
x=3 to get y=20
The missing value of x is 3 because same of x we get two different value of y.

Answer:
(4 , -3)
Step-by-step explanation:
Put "y" by itself on one side to isolate it
3x - y = 15
3x = 15 + y
3x - 15 = y
Substitute "y" in the second equation for "3x - 15"
x + (3x - 15) = 1
4x - 15 = 1
4x = 16
x = 4
Then, plug 4 into x in any of the equations
4 + y = 1
y = -3
(4 , -3)
What are the potential solutions to the equation?
If this is the full question; What are the potential solutions to the equation below? 2In(x+3)=0
then the answer is; 2ln(x + 3) = 0
ln[(x + 3)²] = 0
(x + 3)² = 1
x + 3 = ±√1
x + 3 = ±1
x = 1 - 3, -1 - 3
x = -2, -1 - 3
x = -2, -4
when checking solution; x = -4 in the original equation does not hold true. so you drop x = -4 from the solution set.
therefore;
x = -2
