Suppose you are asked to find the area of a rectangle that is 2.1-cm wide by 5.6-cm long. Your calculator answer would be 11.76 cm^2. Now suppose you are asked to enter the answer to two significant figures. (Note that if you do not round your answer to two significant figures, your answer will fall outside of the grading tolerance and be graded as incorrect.) Write your answer to two significant figures and include the appropriate units

Answers

Answer 1

Answer:

The area of the rectangle is 12 cm² (to two significant figures)

Step-by-step explanation:

To determine the area of a rectangle that is 2.1-cm wide by 5.6-cm long,

The area of a rectangle is given by

Area = l × w

where l is the length

and w is the width

From the question,

l = 5.6 cm

and w = 2.1 cm

Hence, Area of the given rectangle will be

Area = 5.6 cm × 2.1 cm

Area = 11.76 cm²

Now, we will convert the answer to two significant figures

Then,

Area = 12 cm²

Hence, the area of the rectangle is 12 cm² (to two significant figures)

A. 20 + 17 + (-1/2) + (-5/2)
B. 2/3 + (-1/3) + 5
C. (-17) + 45 + (-33)
D. 20 + 80 + (-32)

Answers

9514 1404 393

Answer:

  C.  (-17) + 45 + (-33)

Step-by-step explanation:

The order seems appropriate for A, B, D:

  A. = 37 -6/2 = 34

  B. = 1/3 +5 = 5 1/3

  D. = 100 -32 = 68

I would rearrange the numbers in C to put the negative numbers together:

  C. = (-17) +(-33) +45 = -50 +45 = -5

Answer:

c. is the right answer :) hope this helps

if g is the midpoint of ab, classify each triangle by its angles and sides

Answers

Answer:

CFE: Right triangle.

BCE: Acute

BFG: Equilateral

GAF: Obtuse

Step-by-step explanation:

Remember the types of triangles, first the CFE creates a right angle, which is a 90º angle between two of the sides that would be where F is located, so that would be a right triangle.

BCE is an acute triangle since all of its angles are lower than 90º so you don't have any larger than 90º angles, and its sides are not equal to eachother, so different sides and angles below 90º is an acute triangle.

BFG is an equilateral triangle since all of its sides are equal, and it is demonstrated in the figure by putting a little line in the middle of the sides that means that the sides are equal since the three sides of the triangle have them they are all equal making it an equilateral triangle.

GAF is an obtuse triangle, since all of its side are different and it has an angle larger than 90º that creates an obtuse triangle because of its obtuse angle.

Each of the triangles are classified as;

ΔCFE: Right angle triangle.

ΔBEC: Acute triangle

ΔBFG: Equilateral triangle

ΔGAF: Obtuse triangle

1) For the triangle ΔCFE, we can see that it has a right angle at point F. Thus, ∠CFE = 90°. Therefore, we can call ΔCFE right angled triangle.

2) For the triangle ΔBEC, we can see that the three angles namely;∠BEC, ∠BCE, ∠EBC are all less than 90°. Any triangle where the three angles are less than 90° is called acute triangle.

3) For the triangle ΔBFG, we can see that the three sides are equal. Any triangle with it's 3 sides equal is called equilateral triangle.

4) For the triangle ΔGAF, we can see that one of the angles which is ∠G is greater than 90° and any triangle with one of its's angles greater than 90° is called obtuse triangle.

How to write a equation from a graph

Step-by-step explanation:

If i had a graph and i was using gallons per hour i would put gallons on the bottom and hours on the side

Answer/Step-by-step explanation:

So, if there is line on the graph and we need to get its equation in slope-intercept for (y = mx+b where m is the slope and b is the y-intercept). First, we have to take two points that lie on that line. Then, we will use the slope formula (m = y2 - y1 / x2 - x1). Once we get the slope, we have to find the y-intercept aka the b - value in the equation. So, to find this we have to take one of the coordinate point (that lies on the graph and was used to find the slope) and the slope. When you get the b - value, you have to substitute that value and the slope value into the equation. This is how you can write an equation from a graph.

Ex. (2, 3), (4, 9)

m = 9 - 3 / 4 - 2

m = 6/2

m = 3        <--- This is the m value aka the slope

y = mx + b         (In this case, we will use the first point which is (2,3)).

3 = 3(2) + b

3 = 6 + b

b = -3

y = 3x -3

QUESTION 2 Brewsky's is a chain of micro-breweries. Managers are interested in the costs of the stores and believe that the costs can be explained in large part by the number of customers patron­izing the stores. Monthly data regarding customer visits and costs for the preceding year for one of the stores have been entered into the regression analysis and the analysis is as follows: Average monthly customer-visits 1,462 Average monthly total costs $4,629 Regression Results Intercept $1,496 b coefficient $2.08 R2 0.86814In a regression equation expressed as y = a + bx, how is the letter b best described? (CMA adapted)

Answers

Answer:

b is the amount by which the costs of the stores (i.e. y) will increase whenever the number of customers patron­izing the stores (i.e. x) increases by one.

Step-by-step explanation:

How is the letter b best described?

b is the amount by which the costs of the stores (i.e. y) will increase whenever the number of customers patron­izing the stores (i.e. x) increases by one.

That is, b is the coefficient of letter x and it indicates that whenever there is a one unit increase in the number of customers patron­izing the stores (i.e. x), the costs of the stores (i.e. y) will increase by $2.08.

To give an example, the regression equation in the question is expressed as:

y = a + bx ............................ (1)

Where;

y = the costs of the stores = ?

a = Intercept = $1,496

b = coefficient = $2.08

x = the number of customers patron­izing the stores = ?

Assume x = 1, we can predict y by substituting the values to obtain y1 as follows:

y1 = $1,496 + ($2.08 * 1) = $1,496 + $2.08 = $1,498.08

Now, assume x increases by 1 to 2 i.e. x = 2, we can predict y by substituting the values to obtain y2 as follows:

y2 = $1,496 + ($2.08 * 2) = $1,496 + $4.16 = $1,500.16

The the change is y as a result of one unit increase in x from 1 to 2 can then be obtained as follow:

Change in y = y2 - y1 = $1,500.16 - $1,498.08 = $2.08.

This therefore cofirms that b indicates that whenever there is a one unit increase in the number of customers patron­izing the stores (i.e. x), the costs of the stores (i.e. y) will increase by $2.08.

Answer:

55 feet

Step-by-step explanation:

5.5                                   4

                _            =        _

                H                    40

The height of the dinosaur is 52.5 ft.

We know that:

12 inches = 1 ft

So, 1 inch = 1/12 ft

or, 3 inches = 3/12 = 0.25 ft.

So the height of Amir is = 5 ft 3 inch = 5.25 ft.

Let the height of the dinosaur is = x.

So, the ratio is:
