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:

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.

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:

  (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 ...

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".

Answer:

Part A:

Equation: 0.65p=c

Answer: $1.30

Part B:

Equation: 0.05p=c

Answer: $0.10, or ten cents (if two pounds of computers where shipped at this reduced price)

Step-by-step explanation:

To find the total cost, first find the elements you will need. We know that we need to equal c, the cost, and we know that the pounds times 65 cents equals the cost.

0.65p=c

Now, to solve, plug in the amount of pounds.

0.65(2)=c

1.3=c

So the cost of shipping two pounds of computers is $1.30.

Now, to solve part b, we do the same as what we did in part a, except this time it only costs five cents per pound.

Make the equation.

0.05p=c

Also, at the top I put the extra, if two pounds were shipped at the reduced price just in case. But for the explantion to it, just plug to into the equation, then find the answer.

Part A: The equation for the total cost, c, to deliver p pounds is:

c = 0.65p.

The cost for shipping 2 pounds is $1.30.

Part B: The equation, after the reduction of $0.05 in the shipping of per pound is:

c = 0.6p.

Equations are relations between two quantities involving variables raised to multiple powers, making up terms along with numerals.

In the question, we are informed that Charlie's Computer Company charges $0.65 per pound to ship computers.

Part A:-

We are asked to write an equation to determine the total cost, c, to ship p pounds of computers.

We know that the total cost equation is designed as:

Total cost = fixed cost + (per unit cost)*(number of units).

Thus, the required equation is:

c = 0 + 0.65p, {Since c is the total cost, the fixed cost is 0, the quantity of computers shipped is p pounds, and per pound cost of shipping is $0.65}

or, c = 0.65p.

The cost for shipping 2 pounds, can be calculated by substituting p = 2 in the above equation.

Thus, c = 0.65*2 = 1.30.

Thus, the cost of shipping 2 pounds is $1.30.

Part B:-

We are asked to write an equation for the total cost, c, to ship p pounds of computers, when the company reduces the cost to ship computers by $0.05 per pound.

Now, the unit cost of shipping one pound of computers is $0.65 - $0.05 = $0.60.

We know that the total cost equation is designed as:

Total cost = fixed cost + (per unit cost)*(number of units).

Thus, the required equation is:

c = 0 + 0.60p, {Since c is the total cost, the fixed cost is 0, the quantity of computers shipped is p pounds, and per pound cost of shipping is $0.60}

or, c = 0.60p.

Step-by-step explanation:

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!!!
