Read another paragraph and graphic from the text “Overfishing the Oceans.” Then answer the question.
Overfishing is a problem that affects a whole ecosystem. A healthy ocean has a balance of different species. One problem with overfishing is that it takes away many of the top predator fish and disrupts this balance. Overfishing can also disrupt the marine ecosystem in other ways.

Based on the information in the paragraph and graphic, what might be a result of a decrease in tuna populations?
A. Sharks may have difficulty finding food.
B. A rise in squid and mackerel populations.
C. The balance in the food web would be disrupted.
D. All of the above are potential results of a decrease in tuna populations.

Step-by-step explanation:

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Answer:

It would be B

Step-by-step explanation:

Because zoology has a 0.2 percent chance and robotics have a 0.2 chance as well  thus, making option B correct

Answer:

  (a)  The student will be more likely to join the Robotics Club than the Garden Club because P(Robotics) > P(Garden).

Step-by-step explanation:

You want to compare and interpret probabilities of joining a club, given the poll results in the table.

In order of probability, greatest to least, students are planning to join the clubs ...

  Technology > {Robotics, Zoology} > Garden

Comparing against answer choices we see ...

  (a) more likely to join Robotics than Garden — True

  (b) equally likely to join Robotics or Technology — false

  (c) more unlikely to join Zoology than Robotics — false

  (d) more likely to join Garden than Robotics — false

__

Additional comment

The intent of the numbers is to say that higher numbers indicate a greater probability of joining the corresponding club. When the numbers are equal, the probabilities are equal, so you cannot say one is greater than the other.

335.75

Step-by-step explanation:

80 / 4.5 = 17.8

19.75 * 17 = 335.75

Answer: If he has more than 80 feet of planks he can make at least 17 birdhouses, and that's $335.75

Step-by-step explanation:

80/4.5 = 17.7 (at least 17 birdhouses)

17 x 19.75 = 335.75

Answer: 540.4 mm squared

Step-by-step explanation:

Since there are 5 triangles, we can find the area of each one and multiply it by 5:

(bh)/2 * 5

the base is 8 because in an isosceles triangle, you divide the bottom side by 2

(2*20)/2 * 5 =

20 * 5 =

100

We can add this to the base, 440.4, and get a result of 540.4

Answer: 540.4 mm squared

Answer:

See below

Step-by-step explanation:

The first two questions are slope = 0

   a horizontal line has zero slope  

            slope = rise/run  = 0 / run = 0

Greatest y value is + 4   from x = 3 to 4

the least y value is -3 fro x = -4 to -3

Jessica paid more than Amber at lunch.

To find out, we first need to calculate the amount of tip each person left:

Amber's tip = 11.70 x 0.18 = $2.11

Jessica's tip = 12.30 x 0.15 = $1.85

Then we add the cost of the lunch and the tip for each person:

Amber's total cost = 11.70 + 2.11 = $13.81

Jessica's total cost = 12.30 + 1.85 = $14.15

So Jessica paid $0.34 more than Amber for lunch.

Answer: 24

Step-by-step explanation:

Colleen painted 7 windows, some of which were her mother's.

Her dad painted 7+1 (8) windows, and that is twice as much as what her mother was supposed to do. Her mother was supposed to do 4 windows. That means Colleen's share was 3 windows.

If all the kids had to do an equal amount of windows, than each kid had to do 3 windows.

8+7+3+3+3=24

The total windows in the house are 21.

It is an expression contains a relation between different parameters (variables). It contains variable and constant values, along with algebraic operations.

In our given problem, the algebraic relation between different members work output and total windows can be expressed as:

Windows painted by colleen and her mother = 7

Windows painted by father = (Windows painted by colleen and her mother + 1)

                                          = (7 + 1) = 8

∴ Windows painted by father = 8

Now, as given,

2 Windows painted by mother = Windows painted by father

∴ Windows painted by mother = \(\frac{8}{2}\) = 4

and Windows painted by colleen = 7 - 4 = 3

Colleen and her 2 brothers paint equal windows;

∴  They painted 3 windows each.

The total windows in the house is equal to total painted windows by mother, father, colleen and her two brothers:

⇒ 4 + 8 + 3 x 3 = 12 + 9 = 21

Hence the total windows in the house are 21.

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.
