6. Priya and Jax are 20 miles apart in a path when they start walking towards each other. Priya
runs at a constant speed of 6 miles an hour and Jada walks at a constant speed of 2 miles an
hour. How long does it take for them to meet? Explain your reasoning,
Answer:
2 hours 30 minutes
Step-by-step explanation:
Step one
Given data
The total distance to be covered= 20miles
Priya runs at a constant speed of 6 miles an hour
Hence Her speed = 6mph
Jada walks at a constant speed of 2 miles an hour
Hence Her speed = 2mph
let the time taken by them to cover the distance be t
Step two:
from speeed= distance/time
distance= speed*time
so
20=6*t+2*t
20= 6t+2t
20=8t
divide both sides by 8
t= 20/8
t=2.5 hours
That is, it wiil take them 2 hours 30 minutes to meet
The reason is because, the distances covered by them must sum up to 20 miles

The factor or variable other than the ones being studied that, if not controlled, could affect the outcome of an experiment is the _____ variable.
Answer:
Extraneous variable.
Step-by-step explanation:
This variable is not seen to work on its own directly in a lot of cases, they are explained to be occurrences or certain factors that are seen to influence the process of the experiment that are not independent variable. In different surveys of studies, it is said to sometimes posses a negative effect on the data consequentially. Many surveys and research has also shown that some of these variables can be controlled while also some of them cannot be controlled.

Answer:
64 degrees
Step-by-step explanation:
The angles of a triangle add up to 180deg. The measure of angle B = 180-74-22 = 84. Since line segment BD bisects angle B, the measure of angle ABD is 1/2 of 84, or 42. Therefore, the measure of angle BDA = 180-74-42 = 64.

Use finite differences to identify the degree of the polynomial that best describes the data.
Answer:
cubic
Step-by-step explanation:
The degree of the polynomial that best describes the data is quadratic.
What is Polynomials?Polynomials are kind of algebraic expressions consisting of variables, constants and coefficients along with exponents consisting of finite number of terms.
There are different types of polynomials like linear, quadratic, cubic and so on depending on the highest degree of the variables.
Finite difference method is used to find the degree of the polynomial by finding the difference of the values corresponding to the the values of the independent variable which are equally spaced.
Here, x is the independent variable and the values of x are given.
We have,
x : -3 -1 1 3 5 7
y : 4 6 1 -11 -30 -56
Find the first finite difference of the y values, we get,
x : -3 -1 1 3 5 7
y : 4 6 1 -11 -30 -56
First finite difference : 2 -5 -12 -19 -26
This is not constant.
Second finite difference : -7 -7 -7 -7
Second finite difference is constant.
So this is a polynomial equation of degree 2.
Hence the given polynomial is quadratic.

Answer:
Step-by-step explanation:
7x + 8y + 5z
I put the equations in parentheses, assuming that I would be adding both of the equations together. Then, I removed them and combined the like terms. I used two calculators to check my answer, and this should be correct.
Answer:
7x + 8y + 5z
Step-by-step explanation:
To add these to expressions we have to combine like terms:
(4x + 3x) + (3y + 5y) + (2z + 3z) = 7x + 8y + 5z

What is 10.2 divided by something equals 0.8? Please help
Answer:
8.16
Step-by-step explanation:
8.16 divided by 0.8 = 10.2
The value of number will be 12.75.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that;
Number 10.2 divided by something equals 0.8.
Now,
Let the value of number = x
So, We can formulate;
⇒ 10.2 ÷ x = 0.8
Solve for x as;
⇒ 10.2 / x = 0.8
⇒ x = 10.2 / 0.8
⇒ x = 12.75
Thus, The value of number = 12.75

I need help finding the y-intercept of these, I am no good with slope and tables. ;-;
Answer:
1. -4
2. 6
3. -6
(i hope this is right •_•)
Step-by-step explanation:
First table
When the x coordinate is 0, that point is your y intercept. For the first one, your y intercept is -4.
Second table
For the second one, we need to do a bit of counting. We can see the x coordinates go before and after zero, but the table does not show us 0. So, we're going to have to calculate the slope. Bear with me here, I'm a little tired and this might be rambling ;-;
So, the formula for calculating slope is [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. I'm going to use those first two points to get my slope. We're going to say the first point is point 1 and the second point is point 2 (genius, i know lol). So, let's substitute in the x and y values.
[tex]\frac{9-12}{-3-(-6)}[/tex]
And simplify...
[tex]\frac{-3}{3}[/tex]
So, your slope is -1. We can use that. We just have to count down.
If the x is -2, the y is 8. If the x is -1, the y is 7. And if the x is 0....(drumroll please) the y is 6! So, your y intercept is 6.
Third table
Now, this table isn't very nice either and doesn't have an x as 0 for us. Hmpf. But we can still do what we did above. I'll just skip the explanation and you can observe my steps.
[tex]\frac{-3-(-5)}{9-3}[/tex]
[tex]\frac{2}{6}[/tex]
[tex]\frac{1}{3}[/tex]
Let's count down....
If x = 3, y = -5
If x = 2, y = -5 1/3
If x = 1, y = -5 2/3
If x = 0, y = -6

the coordinates of point A(-3,2) and the coordinates of point B(4,1) what is the length of AB?
9514 1404 393
Answer:
AB = 5√2
Step-by-step explanation:
The length of AB is given by the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((4 -(-3))² +(1 -2)²) = √(7² +(-1)²) = √(49 +1) = √50
The length of AB is √50 = 5√2.
