Elevation questions:

1. how much higher is 500 than -400 m

2. how much higher is -200 m than 450 m

Answer: 900 and 650

Step-by-step explanation: so because 400 is negative, it would take 400 to get to 0 and 500 more to get to 500 so 900 for 1. And same thing for the second one, -200 plus 200 is 0 plus 450, it’s 650

you have a bag of 10 marbles. three of them are red ,five are blue, and two are green.what is the probability of not picking a green marble out of the randomly

**Answer:**

Not probabillity of picking a green marble is 80%

**Step-by-step explanation:**

**Answer:**

.80 or 4/5

**Step-by-step explanation:**

Probability is all about figuring out what you are or not going to get.

One good trick of figuring this out is taking what you don't want, (here its green marbles) take them out, then add all the marbles (G,B,R) and divide. Here you are dividing 8 by 10 which comes out to .80

The only other thing to do is simplify if needed. .80 turns into 8/10 and the only thing that 8 and 10 are divisible by is 2 so it would turn into 4/5

Hope this info can help ;)

There is 5 yellow 3 red 4 green 2 blue and 2 white what is the probability of picking white then green

**Answer:**

2 (I think)

**Step-by-step explanation:**

4-2=2

**Answer:**

1/30

**Step-by-step explanation:**

the probability of picking white is 2/16 simplified to 1/8

the probability of picking a green would equal to 4/15

notice that it is not 4/16, because you already picked out one of the colours, and you are not replacing it, so if you take it out, then there is 15 left to pick from.

you would then multiply

1/8 x 4/15

= 4/120

simplified to

1/30

Find the gradient of the line segment between the points (-2,3) and (-4,-2).

Give your answer in its simplest form.

**Given:**

The two points are (-2,3) and (-4,-2).

**To find:**

The gradient of the line segment between the given points.

**Solution:**

The gradient is also known as slope.

The slope formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The endpoints of the line segment are (-2,3) and (-4,-2). So, the gradient of the line is

[tex]m=\dfrac{-2-3}{-4-(-2)}[/tex]

[tex]m=\dfrac{-5}{-4+2}[/tex]

[tex]m=\dfrac{-5}{-2}[/tex]

[tex]m=\dfrac{5}{2}[/tex]

**Therefore, the gradient of the given line segment is [tex]m=\dfrac{5}{2}[/tex].**

A rectangle is 6 feet long and 4 feet wide. If each dimension is increased by the same number of feet, a new rectangle is formed whose area is 39 square feet more than the area of the original rectangle. By how many feet was each dimension increased?

**Answer:**

Each dimension increased by 3 ft.

**Step-by-step explanation:**

Area of the original rectangle = 4 * 6 = 24 square feet

Increased dimension = x ft

New length = 6 + x

New width = 4 +x

New area = (6 + x)(4 +x) **{Use FOIL method}**

= 6*4 + 6*x + x*4 + x*x

= 24 + 6x + 4x + x²

= x² + 10x + 24

New area = 24 + 39

x² + 10x + 24 = 63

x² +10x + 24 - 63 = 0

x² + 10x - 39 = 0

x² + 13x - 3x - 3*13 = 0

x (x + 13) - 3(x + 13) = 0

(x + 13)(x -3) = 0 **{Ignore x + 13, as it gives negative value}**

x - 3 = 0

x = 3
