Answer:

Worldwide, hundreds of marine species have been negatively impacted by marine debris, which can harm or kill an animal when ingested or they become entangled, and can threaten the habitats they depend on.

This lost or abandoned gear is a major problem because it can continue to capture and kill wildlife, damage sensitive habitats, and even compete with and damage active fishing gear.

Step-by-step explanation:

The key idea is that pollution is threatening marine life impact of marine life and the source of marine debris.

Marine debris is risky to a wide variety of marine animals. Animals can ingest debris, which can cause health problems or death, or they may get caught in debris, which can be equally harmful. In addition, marine debris harms the environments in which many species rely on being alive.

The greater part of marine garbage is caused by human activity on land. Marine debris is produced by poor waste management methods, dumping waste, stormwater discharge, and natural disasters such as tsunamis and hurricanes. Furthermore, ocean-based sources, such as wasted fishing gear, contribute to the problem.

The number of ways that Grant can arrange 3 of his 10 plants on a window ledge is 120 ways

The number of ways that Grant can arrange 3 of his 10 plants on a window ledge will be:

= 10!/(10! - 3!)3!

= 10!/7!3!

= (10 × 9 × 8)/(3 × 2)

= 120

When the parade organizer received 8 entries for floats, the number of ways that he can arrange 4 floats out of the 8 entries will be:

= 8!/(8! - 4!)4!.

= 8!/4!4!

= (8 × 7 × 6 × 5)/(4 × 3 × 2)

= 70

Answer: The correct answer is D.

Step-by-step explanation: A and B are incorrect because you can plug in 5 for x to get 2, and there are multiple values that can be greater than 5. C is incorrect because you cannot reach lower than 2. Therefore, the correct answer is D.

The y values are all greater than or equal to 2.

The correct option is D.

Given,

Function : f(x) = |x − 5| + 2

Here,

A function is a law that relates a dependent and independent variable.

The function is

f(x) = |x − 5| + 2

The domain of the function is all negative and positive integers.

The range is all the possible function values, the function value will always be greater than or equal to 2.

At x = 5 , f(x) = 2

The exponential function is given by [tex]I(t) = 50000(1.15)^t[/tex]. The initial investment of $50,000 grows at a rate of about 15% annually.

An equation is an expression that shows the relationship between two or more numbers and variables.

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the rate of increase per period.

Let I(t) represent Jennifer’s investment account balance after t years, hence:

a = 50000, b = 100% + 15% = 115% = 1.15

[tex]I(t) = 50000(1.15)^t[/tex]

The exponential function is given by [tex]I(t) = 50000(1.15)^t[/tex]. The initial investment of $50,000 grows at a rate of about 15% annually.

Answer: Cylinder B is 50% bigger than cylinder A

Cylinder A volume:

= πr²h

= π(10)²(5)

= 500π

Cylinder B volume:

= 750π

Cylinder B bigger than Cylinder A by:

= (750π - 500π)/500π × 100 = 50%

[tex]\hrulefill[/tex]

Hence, cylinder B is bigger than cylinder A by 50%

Answer:

Cylinder B is 50% bigger than Cylinder A

Step-by-step explanation:

[tex]\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]

Cylinder A

Given:

Substituting the given values into the formula:

[tex]\implies \sf Volume_A=\pi (10)^2(5)=500\pi \:in^3[/tex]

Cylinder B

Given:

[tex]\implies \sf Volume_B=750\pi \:in^3[/tex]

Percentage Change

[tex]\begin{aligned}\sf percentage\:change & =\sf \dfrac{final\:value-initial\:value}{initial\:value} \times 100\\\\& = \sf \dfrac{Volume_B-Volume_A}{Volume_A} \times 100\\\\& = \sf \dfrac{750\pi-500\pi}{500\pi} \times 100\\\\& = \sf \dfrac{1}{2} \times 100\\\\& = \sf 50\%\end{aligned}[/tex]

Answer:

Mike started off the day with $27.

Step-by-step explanation:

Using the information given to us, we can set up an equation. Knowing that Mike ended the day with $7, and the amount of money that he spent and received can help us set up an equation. The amount of money that he started the day off with, is unknown, and recognized as x.  [tex]7=x-22-3+5[/tex]

To solve this, we can simply solve the numbers that we know on the right hand side, to get this:

[tex]7=x-20[/tex]

Now, to get our final answer we must isolate x. We can do this by simply adding 20 to both sides. This cancels out the -20 on the right, and makes the 7 on the left become 27.

[tex]27=x[/tex]

Therefore, Mike started the day off with $27.

Therefore, 110 calories are in 1 serving of milk.

Given, Joe consumes 530 calories by drinking 1 serving of juice, 2 servings of milk, and 1 soda.

Darius consumes 370 calories by drinking 2 servings of juice and 1 serving of milk.

Marian consumes 510 calories by drinking 3 servings of milk and 1 soda.

Linear programming, commonly known as LP, is a straightforward technique for representing complex real-world interactions by means of a linear function.

Now,

Let the calories in one serving of milk be x

Let the calories in one serving of juice be y

Let the calories in one serving of soda be z

For Joe, the equation to show the amount of calories is

2x + y + z = 530 -----(1)

For Darius, the equation to show the amount of calories is

x + 2y = 370 ------(2)

For Marian, the equation to show the amount of calories is

3x + z = 510 ------(3)

Now, y=370/2-x/2 and z=510-3x substitute in the equation 2x + y + z = 530.

2x+185-0.5x+510-3x=530

⇒695-1.5x=530

⇒1.5x=165

⇒x=110 calories

Hence, 110 calories are in 1 serving of milk.

-n - 3  =   -1 • (n + 3)

-2 • (n + 3) -  7 • (2n + 5)

Based on the calculations, the equation of the triangle's line of symmetry is equal to: B. y = x - 1.

First of all, we would determine the midpoint where the line of symmetry passes through points A and B:

Midpoint at point A = (3 + 7)/2 = 10/2 = 5.

Midpoint at point B = (6 + 2)/2 = 8/2 = 4.

Point D = (5, 4)

Mathematically, the standard equation of a line is given by y = ax + b.

D(5, 4); 4 = 5a + b   ....equation 1.

C(4, 3); 3 = 4a + b    ....equation 2.

Subtracting eqn. 2 from eqn. 1, we have:

1 = a

Next, we would find the value of b:

4 = 5a + b

4 = 5(1) + b

b = 4 - 5

b = -1.

Therefore, the equation of the triangle's line of symmetry is given by:

y = ax + b

y = x(1) + (-1)

y = x - 1.
