The Endpoints Of AC Are A(-8, 9) And C (1, -3). Point B(-2, 1) Lies On AC. Whatis The Ratio AB: BC?A
Answer 2

Answer:

C

Step-by-step explanation:

Find the distance of AB:

Distance formula: [tex]\sqrt{[(-8)-(-2)]^2+(9-1)^2}[/tex]

[tex]\sqrt{(-6)^2+(8)^2}=\sqrt{36+64}=\sqrt{100}=10 units[/tex]

Find the distance of BC:

Distance formula: [tex]\sqrt{[(-2)-1]^2+[1-(-3)]^2}[/tex]

[tex]\sqrt{(-3)^2+4^2}=\sqrt{9+16} =\sqrt{25} =5 units[/tex]

AB=10 units

BC=5 units

AB:BC = 10:5=2:1

What are the numbers?​

Answers

Answer:

80 and 20

Step-by-step explanation:

Let the 1st no. be 'x'.

2nd no. should be 'x + 60'.

If the larger no.(x + 60) is divided by the smaller number(x), the quotient is 4.

=> (x + 60)/x = 4

=> x + 60 = 4x

=> 60=4x-x

=> 60=3x

=> 60/3 = x

=> 20 = x

No. are x = 20 and x+60 = 20+60= 80

Answers

Answer:

in 8 years each school will have about 1,040 students

30x + 800 = -25x + 1240

3) origin is (0,0)
4) A is the dot that is height is the middle. B is the highest dot. C is the lowest dot
5) (4,6)
6) (2,9)
7) (0,4)
8) the correct ordered pair is (7,3) because it is (x,y) and allie switched between the two

1. The X axis is the line going left and right

2. The Y axis is the line going up and down

3. The origin is the point where the X and Y axis meet; (0,0); by the 0

4. The points will be written as A, B, C. This is going from left to right. So the first box on the coordinate plane furthest to the left with be labeled with A. Then the second box furthest from the left; the middle box; will be labeled with B. Then the last box will be labeled C

5. (4,6)

6. (2,9)

7. (0,4)

8. When Allie identified the point, she mixed the X and Y coordinates. To identify a point you first want to find the point following the X axis. Then do the same with the Y axis. After doing this you should have 2 numbers, in which are 3 and 7. Now when writing the coordinates, the X axis ALWAYS comes first. So it should look like (7,3)

The function ggg models the number of mosquitoes (in millions of mosquitoes) in a certain area as a function of rainfall (in centimeters) in that area.

Answers

Answer:

6cm produces the largest mosquito

Step-by-step explanation:

The question has missing details.

From the complete question, the function is:

[tex]g(x) = 12x-x^2[/tex]

Required

Which area of rainfall produces the most mosquito

This implies that, we calculate the maximum of the function.

This is calculated as:

[tex]Max = -\frac{b}{2a}[/tex]

We have:

[tex]g(x) = 12x-x^2[/tex]

Rewrite as:

[tex]g(x) = -x^2 + 12x + 0[/tex]

From the above:

[tex]a= -1[/tex]

[tex]b = 12[/tex]

[tex]c = 0[/tex]

So, we have:

[tex]Max = -\frac{b}{2a}[/tex]

[tex]Max = -\frac{12}{2 * -1}[/tex]

[tex]Max = \frac{12}{2}[/tex]

[tex]Max = 6[/tex]

This implies that:

[tex]x = 6[/tex] ---- the maximum

When rainfall is at 6cm, there is a maximum number of mosquitoes

The maximum is then calculated as:

[tex]g(x) = 12x-x^2[/tex]

[tex]g(6) = 12 * 6 - 6^2[/tex]

[tex]g(6) = 72 - 36[/tex]

[tex]g(6) = 36[/tex]

The maximum number of mosquito is 36 million

Which statement is true about the lines 3−2=27 3 y - 2 x = 27 and 4−2=36 4 y - 2 x = 36 ?

Answers

The two lines 3 y - 2 x = 27 and 4 y - 2 x = 36 are parallel to each other because their slopes (i.e., -2/3 and -2/4) are equal.

What are parallel lines?

Parallel lines are lines in a plane that do not intersect and are always the same distance apart. They have the same slope and will never meet, regardless of how far they are extended.

Therefore, the correct answer is as given above. It can be concluded that lines 3 y - 2 x = 27 and 4 y - 2 x = 36 are parallel lines to each other for their slopes (i.e., -2/3 and -2/4) are the same.

A point is reflected across the x-axis. The new point is (5,-3.5). What is the distance between the two points?

Answers

Answer:

Distance between the points = 7 units

Step-by-step explanation:

If a point P(h, k) is reflected across x-axis, rule to be followed will be,

P(h, k) → P'(h, -k)

By this rule,

If the coordinates of new point P' are (5, -3.5)

Then the coordinates of pre-image point P will be (5, 3.5)

By using formula to get the distance between two points,

Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

Distance between (5, 3.5) and (5, -3.5) = [tex]\sqrt{(5-5)^2+(3.5+3.5)^2}[/tex]

= [tex]\sqrt{0+7^2}[/tex]

= 7 units

find the angle of 1 and 3

Answer:

Angle of 1 and 3 as 90*

Step-by-step explanation:

This is because all angles are the same meaning all angles are 90*. Even 1 and 3. Brainiest and a thank you?!

Answer:

We really aren't provided with enough information to give you the answer. I'll explain how to find them, but you should comment on my response and tell be if it gives you any values at all to work with.

So, ∠1 and ∠3 are vertical angles, which means they are equal to each other.

Along with that, ∠2 and ∠4 and also vertical angles, so they're equal to each other as well.

Now we have the information:

∠1 = ∠3

and

∠2 = ∠4

__________________________________________________________

Given that both of the two lines are intersecting, each angle has two angles that it is supplementary to.

Supplementary angle are angles that when added together equal exactly 180°.

A perfectly straight line's angle it 180°.

Using this knowledge, you can find that ∠1 is supplementary to ∠2, ∠2 is supplementary to ∠3, ∠3 is supplementary to ∠4, and ∠4 is supplementary to ∠1.

If that's still confusing, here's it explained simpler:

∠1 + ∠2 = 180°

∠2 + ∠3 = 180°

∠3 + ∠4 = 180°

∠4 + ∠1 = 180°

__________________________________________________________

But still - you haven't given us the information to find these values. Are you given even one angle measurement to work with?? If so, comment it here and I'll work it out for you.

P(chocolate) =

P(vanilla) =

P(strawberry) =

P(mint chip) =

P(other) =

Answers

Chocolate = 18%

Vanilla = 25%

Strawberry = 12%

Mint Chip = 10%

Other = 35%

The explanation for me getting these exact percentages is because of the formulas given for calculating the percentages from specific numbers and real world problems like this. When you are trying to find the calculation precentages of these types of questions, you divide the number by the total surveyed and multiple by 100.

Example:

125 / 500 = 0.25

0.25 x 100 = 25%

So, this is also how I got the other numbers, just change the "125" to the other numbers.

The experimental probability of each outcome in the sample space are:

P(chocolate) = 18%, P(strawberry) = 12%, P(vanilla ) = 25%, P(mint chip) = 10% and P(other) = 35%

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Flavor               Number of people

chocolate                  90

strawberry                 60

vanilla                        125

mint chip                    50

other                          175

So, the Experimental probability are:

P(chocolate)= 90/ 500 x 100 = 18%

P(strawberry) = 60/ 500 x 100 = 12%

P(vanilla ) = 125/ 500 x 100 = 25%

P(mint chip) = 50/ 500 x 100 = 10%

P(other) = 175/ 500 x 100 = 35%
