What number is halfway between 8.20 and 8.30

Answer:

b (0, 4)

Step-by-step explanation:

The other options already have an input (the x) in the function so it must be b.

Las otras opciones ya tienen una entrada (la x) en la función, por lo que debe ser b.

Answer:

17.  A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right.

18. Zero slope means that the line is horizontal. Just like the line that makes the top of a “Z” is horizontal. No slope means that the line is vertical.

19. Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

20. Yes, they did because 2/6 is equivalent to 1/3.

21. A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.

Subtract how much more angle 1 is from the total. :

112 - 48 = 64

Divide by 2:

64/2 = 32

Angle 2 = 32 degrees

Answer:

measure of angle 2 is 32 degrees.

Step-by-step explanation:

I will refer to the measure of the angles as m1 and m2 (I don't have the angle symbol on my keyboard).

we are looking for measure of angle 2, so let's call m2 "x".

so,

m2 = (x)

m1 = (48 + m2) or m1 = (48 + x)

and we know that:

m1 + m2 = 112

so we substitute the values above into the equation.

m1 + m2 = 112

(48 + x) + (x) =  112

combine like terms:

42 + x + x = 112

42 + 2x = 112

subtract 42 from both sides, leaving us with

2x = 64

divide by 2, giving us

x = 32

remember that we are looking for m2, which is x, so m2 is 32 degrees. hope this helped! (:

Answer: $55.35

Step-by-step explanation:

The simple interest on $2700 at a rate of 8.2% per year for 3 months will be $55.35.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

Given that,

Jack borrows $2,700 at a rate of 8.2% per year.

Principle amount P = 2700

Rate of interest = 8.2% per year

Rate of interest per month ⇒ 8.2/12 = 0.683%

The simple interest for the  T time period is given by,

Interest = PRT/100

Interest = (2700 × 0.683 × 3)/100 = $55.35

Hence "The simple interest on $2700 at a rate of 8.2% per year for 3 months will be $55.35".

Step-by-step explanation:

Answer:

the median in that numbers is 6

Step-by-step explanation

their are total 7 number which is odd

so the formula is

median = ( n + 1 /2 )^th term

now,

→ ( 7 + 1 / 2 )

→ 8/2

→ 4th term

therefore, 4th term is the median and 4th term is 6 itself.

Answer:

  c = 81

Step-by-step explanation:

The equation x² -c = 0 can be factored as ...

  (x -√c)(x +√c) = 0

which has roots ±√c.

The roots are given as ±9, so we have ...

  ±9 = ±√c

  c = (±9)² = 81

The value c = 81 makes the equation have ±9 as solutions.

We have drawn scatter diagram and given an example of a data point that affects the appropriateness of using a linear regression model and  of a school that is cost effective and rated highly by parents.

The scatter diagram plots two sets of numerical data, one on each axis, to see if there is a link between them. The points will fall along a line or curve if the variables are correlated.

We are using graphing calculator to show the points to make scatter diagram

If a linear model is adequate, the histogram should be about normal, and the residuals scatterplot should have random scatter. The linear model is not adequate if we detect a curved connection in the residual plot.

Parents can help with events and activities at school, as well as communicate with instructors. They can also be active at home in a variety of ways, including as assisting their children with homework and other obligations, and engaging in talks about educational principles and attitudes.

Answer:

D)

Step-by-step explanation:

from point A, draw an arc that intersects both sides of the angle

From point A, draw an arc that intersects both sides of the angles. Thus, the correct option is D.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

An angle bisector is a line or ray that divides an angle into two equal parts. The angle bisector divides the angle into two smaller angles that have the same measure.

Thus, the correct option is D.

Answer:

  (x -3)/(x -1)  and  (x +2)/(x -3)

Step-by-step explanation:

If you want the product of two fractions to be a/b, then 'a' must be a factor in the numerator of one of them, and 'b' must be a factor in the denominator of one of them.

'a' and 'b' are already in the numerator and denominator of a/b, so we can choose the other fraction to be something that has a value of 1, such as c/c.

  (a/b)(c/c) = (ac)/(bc) = a/b

The intermediate product (before we reduce the result) has a numerator of 'ac' and a denominator of 'bc'. We can split those into two parts however we like. For example, we can get the same result by multiplying ...

  (a/c)(c/b) = (ac)/(bc) = a/b

So, a simple answer to your question could be ...

  [tex]\left(\dfrac{x-3}{x-1}\right)\times\left(\dfrac{x+2}{x-3}\right)=\dfrac{x+2}{x-1}[/tex]

Answer:

Step-by-step explanation:

Let the width be w. The length is then 3w (length is 3 times its width).

The formula for the perimeter is 2l + 2w (2 times the length + 2 times the width)

So, in our case we have 2(3w) + 2w = 72

                                  6w + 2w = 72

                                  8w = 72   divide both sides by 8

                                  w = 9

So the length = 3w = 3 x 9 = 27

Double check: we have l = 27 and w= 9. (2 x 27) + (2 x 9) = 54 + 18 = 72  Yay!!!
