Can I please have help on 9-11?

If two straight lines intersect and one angle is 30 degrees what are the other three angles

mel-nik [20]

Easey peasy
oposite angle is equal
other angles are supplementary (supplementary means add to 180, and a straight line=180 so if you look at 2 lines intersecting and think for a little bit, you wiill see why)

oposite angle=30
other angle is adds to 180
30+other=180
subtract 30
other=150
other is oposite other other
other=other other
150=other other

angles are
150,30,150

5y + 10x = 0 y = - 3x Plz help me the photo is the directions for the problem

enyata [817]

When substituting, you want to take the y value from one equation and plug it into the y variable in the other equation to find the x value. When you find the c value, you plug the number into one of the equations to get your y value.

Finding the Median from a Dot Plot

MAXImum [283]

Answer:

median rainfall for highland storms = 18mm

median rainfall for lowland storms = 18mm

or

median rainfall for lowland storms = 17mm if the list of numbers is

2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

Step-by-step explanation:

The median is the middle number of a sequence of ordered numbers.

The formula for the median is:

median = (n + 1 )/ 2

where n = total number of values

Note: the number that you find with this formula is the position. SO you have to go to the sequence of numbers and find the number that lies in that position.

Highland storms:

4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

The numbers are already in ascending order so we can proceed.

n = 15

∴ median = (15+1)/2

= 16/2

= 8

The median is the umber in the 8th position

so, the median rainfall for highland storms is 18mm

Lowland storms:

4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

The numbers are already in ascending order so we can proceed.

n = 15

∴ median = (15+1)/2

= 16/2

= 8

The median is the number in the 8th position.

∴ median rainfall for lowland storms is = 18mm

Unclear: if this is the list of numbers:

2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

then the median would be:

n = 16

median = (16+1)/2

= 17/2

= 8.5

This means the median lies between the numbers in the 8th and 9th position.

∴ The median is = (16 + 18)/2

= 34/2

= 17

An airplane can seat up to 175 passengers. The airline has already sold 87 tickets for a flight on the airplane. Which

spayn [35]

The inequality is solved, and then, the graph is given at the end of this question.

------------------

87 tickets have already been sold.
x can still be sold.
In total, the number of tickets sold is 87 + x.
The airplane can seat 175 passengers, thus, the total can be at most 175, that is:

$87 + x \leq 175$

$x \leq 175 - 87$

$x \leq 88$

The solution is given on a graph at the end of this answer.
