What conclusion can be drawn about why volunteer divers are essential in helping the rescue
efforts of coral reefs?
A. The volunteer divers receive the same training as the marine scientists.
B. The faster the volunteer divers are trained, the quicker the coral reefs can be saved.
C. The more volunteer divers that participate, the faster the recovery attempt can occur.
D. The volunteer divers that help save coral reefs will motivate others to want to join in this
effort.
Bart R
The correct answer is C. The more volunteer divers that participate, the faster the recovery attempt can occur.
What are threats to coral reefs?There are numerous dangers to coral reefs, such as:
Climate Change - Coral bleaching is brought on by rising sea temperatures, which can result in coral death.
Pollution: Excess nutrients in the water from runoff from agriculture, sewage, and other sources can result in algae blooms that prevent coral from receiving sunlight, which ultimately kills the coral.
Overfishing - Removing an excessive number of fish can upset the delicate balance of the reef ecosystem and harm the coral.
Since they can contribute more labour to aid in the restoration and maintenance of coral reefs, volunteer divers are crucial to the rescue operations of coral reefs.
Hence, the correct answer is C. The more volunteer divers that participate, the faster the recovery attempt can occur.

Lena buys a brand new washing machine and a dryer for $7500
.
The washing machine costs 70%
of the price of the dryer.
What is the price of the dryer?
Answer:
$2250
Step-by-step explanation:
if the cost of the washing machine is 70% of the cost she paid. then the cost of the dryer must be:
100-70 =30%
Now, to find the cost of the dryer, you just have to find 30%of 7500
30/100x 7500 = 2250
Thus, the dryer costs $2250.

The american heart association is about to conduct an anti-smoking campaign and wants to know the fraction of americans over 26 who smoke. Suppose a sample of 897 americans over 26 is drawn. Of these people, 637 don't smoke. Using the data, estimate the proportion of americans over 26 who smoke.
we can estimate that about 29.0% of Americans over 26 smoke based on this sample.
To estimate the proportion of Americans over 26 who smoke, we need to use the sample proportion, which is the number of people in the sample who smoke divided by the total sample size.
In this case, the sample size is 897 and the number of people who don't smoke is 637, so the number of people who do smoke is:
897 - 637 = 260
So the sample proportion of Americans over 26 who smoke is:
260 / 897 = 0.290

I have a rectangular prism with a height of 30cm, a length of 15cm, and a width of 10cm. What is the volume of my prism? V= Bh B= area of the base of the rectangular prism a= L x W
Answer: V = 4500 cubic units or units^3
Step-by-step explanation:
So far, we know that the givens are:
a height of 30cm, a length of 15cm, and a width of 10cm
So we have to find the volume. The formula for volume is just V = lwh which means that the volume equals the length times the width times the height.
V = (l)(w)(h)
Now, all you have to do is to substitute the given numbers into the equation:
V = (15)(10)(30)
Simplify that:
V = 4500
Put it in the terms:
V = 4500 cubic units or units^3
Hence your answer!

Answer:
3
Step-by-step explanation:
The range of a function is the set of all possible output values (y-values).
The given diagram shows the graph of a rational function with a horizontal asymptote at y = 3 (indicated by the dashed line).
An asymptote is a line that the curve gets infinitely close to, but never touches.
Therefore, as there is an asymptote at y = 3, the curve of the function will never touch the line y = 3, and consequently the value of y = 3 is restricted from the range of the function.
a union organization would like to represent the employees at the local market. a sample of the employees revealed 74 of 120 were in favor of the union. does the union have the required 3 to 2 majority?
Yes, the union has the required 3 to 2 majority.
Given that a sample of the employees at the local market who would like to be represented by the union was found to be 74 out of 120. The fraction of employees in favor of the union is `74/120`.
This can be reduced to `37/60`. Therefore, the fraction of employees not in favor of the union is `1 - 37/60`.This is equal to `23/60`.
Therefore, the ratio of employees in favor of the union to employees against the union is `37:23`. This can be reduced to `3:2`.
Hence, the union has the required 3 to 2 majority.

Identify the quadric surface by name. Find and describe the xy-, xz-, and yz-traces, when they exist.
16x^2-16y^2-z=0
A. Hyperbolic paraboloid; xz-trace: 16x^2-z=0 (parabola); yz-trace: 16y² + z = 0 (parabola)
B. Elliptic paraboloid; xz-trace: 16x²-z=0 (parabola); yz-trace: 16y²+z = 0 (parabola)
C. Elliptic paraboloid; xz-trace: 16x² -z = 0 (hyperbola); yz-trace: 16y² + z = 0 (hyperbola)
D. Elliptic cone; xz-trace: 16x2 -z=0 (hyperbola); yz-trace: 16y²+z=0 (hyperbola)
A. Hyperbolic paraboloid; xz-trace: \(16x^2-z=0\) (parabola); yz-trace: \(16y^2 + z = 0\) (parabola)
To identify the quadric surface, we can analyze the equation:
\(16x^2 - 16y^2 - z = 0\)
This equation represents a hyperbolic paraboloid.
To find the xy-, xz-, and yz-traces, we set one variable to zero and solve for the other two variables:
1. xy-trace (z = 0):
\(16x^2 - 16y^2 = 0\)
Simplifying, we get:
\(x^2 - y^2 = 0\)
This is a difference of squares, which factors as:
(x - y)(x + y) = 0
So the xy-trace consists of two lines: x = y and x = -y.
2. xz-trace (y = 0):
\(16x^2 - z = 0\)
Solving for z, we have:
\(z = 16x^2\)
This represents a parabola opening upwards in the xz-plane.
3. yz-trace (x = 0):
\(-16y^2 - z = 0\)
Solving for z, we get:
\(z = -16y^2\)
This represents a parabola opening downwards in the yz-plane.
Therefore, the xy-trace consists of two lines (x = y and x = -y), the xz-trace is a parabola opening upwards, and the yz-trace is a parabola opening downwards.

For the piecewise function, find the values h(- 5), h(0), h(1), and h(4).
Answer:
h(-5) = 2h(0) = 1h(1) = 3h(4) = 6Step-by-step explanation:
You want the value of the piecewise function for various values of x.
Piecewise functionThe first step in evaluating a piecewise function is determining which domain is applicable to the value of x you have. Then you use the corresponding function, evaluating it in the usual way.
h(-5)For x = -5, the applicable domain is x < -3, so the function is ...
h(-5) = -4(-5) -18 = 20 -18
h(-5) = 2
h(0)For x = 0, the applicable domain is -3 ≤ x < 1, so the function is ...
h(0) = 1
h(1), h(4)For x = 1 or 4, the applicable domain is x ≥ 1, so the function is ...
h(1) = 1 +2 = 3
h(4) = 4 +2 = 6

Calc how much interest you would earn on a deposit of $8500 at 2.75%,
compounded annually, for a term of 4 years?
9514 1404 393
Answer:
$974.28
Step-by-step explanation:
The formula for the account balance is ...
A = P(1 +r)^t
Subtracting the principal gives the amount of interest.
I = P((1 +r)^t -1)
i = $8500(1.0275^4 -1) ≈ $974.28
You would earn $974.28 in interest over that time period.

and the width be w
so
w= x
L=x+8
P= 180cm
P= 2L+2W
180= 2(x+8)+2(x)
180= 2x+16+2x

180= 4x+16
180-16= 4x
164= 4x
x= 164/4
