Which of these provides the best evidence that an environmental change has occurred?

Answer:

74

Step-by-step explanation:

"The mode is the value that appears most often in a set of data values."

So, if we look at this data, we can conclude that the mode is 74 because 74 appears 3 times (with 85 being second at twice).

Answer:

-6

Step-by-step explanation:

tbh I just used a calculator

Answer:

-2x + 4y - 6

Step-by-step explanation:

Our equation is this:

-2x + 8y - 11 - 3y - y + 5

Now, combine like terms:

-2x + 4y - 6

This equation is the most simplified it can be.

Hope this helps :)

Answer:

1562.05

Step-by-step explanation:

A = P(1 + r/n)^(n*t)

A = 1240(1 + 0.08/1)^(3*1)

A = 1562.04288

A = 1562.05

Answer:

Step-by-step explanation:

For A, 7x=21, it is asking, 7 multiplied by what number is 21? We can try to figure it out. Let's start with 0.

7(0)≠21

Then 1.

7(1)≠21

7(2)≠21

7(3)=21

Therefore, for question a, the answer is 3.

For question b, it's asking 6 minus what is 2.

With this one, we can say it is 4, since 6-4=2.

Now moving on to B.

a) 2x+4=16

We need to isolate x in order to find it's value.

So we can begin with subtracting 4 from both sides, getting us:

2x=12

Then, if we divide both terms by 2, we get x.

x=12/2

x=6.

b)

3 x (z/4)=9

Again, we need to isolate z.

So, we multiply both sides by 4, getting us

3z=36

then we divide by 3

z=36/3

z=12

c) 16-x=2

Here we simply subtract 16 from each side, then flip the signs to get positive x.

So, 16-x=2

-x=-14

x=14

d) 4k=20

This is essentially asking, 4 times what number is 20?

So we can divide both sides by 4 and get

k=20/4

k=5

Answer:

B

Step-by-step explanation:

even if the variables confuse you just look at the inequalitiy symbols; all of them, except for B, are not correct

you wouldn't use < because this implies you can't spend $150

you wouldn't use > or ≥ because these imply you can afford to spend more than $150

1/6a - 1/6

Step-by-step explanation:

-2/3a + 5/6a can be simplified:

1. Make a common denominator → -4/6a + 5/6a

2. Simplify '-4/6a + 5/6a' → 1/6a

Answer:

1/6a - 1/6

Answer:

[tex] - \frac{1}{6} (a +1 ) \\ [/tex]

Step-by-step explanation:

[tex] - \frac{2}{3} a + \frac{5}{6} a - \frac{1}{6} \\ - \frac{2 \times 2}{3 \times 2}a + \frac{5}{6} a - \frac{1}{6} \\ - \frac{4a + 5a}{6} - \frac{1}{6} \\ - \frac{1}{6} a - \frac{1}{6} \\ - \frac{1}{6} (a + 1) \\ [/tex]

The triangle shown is a right triangle shown by the little square inside of it.

Area of a triangle is 1/2 x height x base

Rotating the shown triangle so the square is at a bottom corner the height is 6 and the base is 6

Area = 1/2 x 6 x 6 = 18 square cm

Answer:

The Rockets' team has the better record.

Step-by-step explanation:

The Blazers hockey team has played 12 games but they won only 7 out of the 12 games, so that means that they loss the other 5 games. So that makes the Blazers record 7 wins and 5 losses.

The Rockets' team has played 8 games but they won only 5 out of the 8 games, so that means that they loss the other 3 games. So that makes the Rockets' record 5 wins and 3 losses.

So, the Rockets' team has the better record because they loss less games than the Blazers team did.

Answer:

  y = 3x +3

Step-by-step explanation:

The slope of the line can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

Using the first two sets of table values, this is ...

  m = (9 -6)/(2 -1) = 3/1 = 3

You can find the point-slope equation using the form ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

  y -6 = 3(x -1) . . . . . using the first point in the table

Solving for y gives ...

  y = 3x -3 +6 . . . eliminate parentheses, add 6

  y = 3x +3

Answer:

stan

Step-by-step explanation:

Stan paid less price per liter of gas which is $0.95 per liter.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Harry filled the 75 L gas tank of his pickup truck for $73.88.

Therefore, The cost of 1L of gas is $(73.88/75) = $0.98 per liter.

And Stan paid $0.95 per liter, So Stan paid less per liter of fuel.
