Answer:

Margaret's estimated length is between 55.575 inches and 61.425 inches.

Step-by-step explanation:

I believe this is enough explanation

Percent error is error in percentage compared to original measurement. The range of values representing Margaret's estimated length is [tex]M \in [ 55.575, \: \: 61.425] \: \rm (in \: inches)\\[/tex]

If the measurement of the object is measured to be M, and the percent error in the measurement is estimated to be E%, and O is the original measurement of the object being measured then:

[tex]\rm M \in O \pm E\% \: \rm of \: \rm O[/tex]

where O is the original measurement of the object being measured.

This decides the range of values in which the original measurement can fall in. It is [tex]\rm [ O - \text{E\% of O}, \: \: O + \text{E\% of O}][/tex]

For the given case, we have:

Original measurement of the desk = O =  [tex]58\dfrac{1}{2} = 58 + 0.5 = 58.5 \: \rm inches[/tex]

E% = percent error in measurement = 5%

Let M denotes the estimated measurement of the desk by Margaret.

Then, [tex]M \in \rm [ 58.5 - \text{5\% of 58.5}, \: \: 58.5 + \text{5\% of 58.5}] \: \rm (in \: inches)[/tex]

5% of 58.5 is:

[tex]\dfrac{58.5}{100} \times 5 = 2.925[/tex] (inches).

Thus, the value of M will lie in:

[tex]M \in \rm [ 58.5 - 2.925, \: \: 58.5 +2.925] \: \rm (in \: inches)\\\\M \in [ 55.575, \: \: 61.425] \: \rm (in \: inches)\\[/tex]

Thus, the range of values representing Margaret's estimated length is [tex]M \in [ 55.575, \: \: 61.425] \: \rm (in \: inches)\\[/tex]

The area of the polygon is the sum of the area of rectangle + area of triangle = 316 cm². (Option C)

The polygon is composed of a triangle and a rectangle.

Area of the polygon = Area of Triangle + Area of Rectangle

Area of Rectangle = length × width

Length = 21 cm

Width = 14 cm

Area of rectangle = 21 × 14 = 294 cm²

Area of Triangle = 1/2(base × height)

Base = 21 - 10 = 11 cm

Height = 18 - 14 = 4 cm

Area = 1/2(11 × 4) = 22 cm²

Therefore:

Area of Polygon = 294 + 22 = 316 cm².

Answer:

table 3 and table 12 show a proportional relationship

The coordinate points in the table D shows proportional relationship.  Therefore, option D is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

A) Slope= (3-2)/(4.5-3) =1/1.5

Slope= (8-4)/(12-8) = 4/4 =1

B) Slope= (60-15)/(4-1)

= 45/5

= 15

Slope= (120-70)/10-5)

= 50/5

= 10

C) Slope= (3-2)/(12-8)

= 1/4

Slope= (5-4)/(16-14

= 1/2

D) Slope= (10-5)/(2-1)

= 5

Slope= (35-25)/(7-5)

= 10/2

= 5

Therefore, option D is the correct answer.

Step-by-step explanation:

1.(12×2+1)/2 - (4×9+1)/4 = 3¼.

2.(5×4+3)/4 - (12×2+5)/12 = 3⅓.

3.(5×7+1)/5 - (10×3+7)/10 = 3½.

4.(3×11+2)/3 - (2×8+1)/2 = 3⅙.

Step-by-step explanation:

I just answered this ...

the first thing we notice : the quadrilateral has 2 pairs of equally long sides with 2 angles being openly 90°.

so, we are dealing with a rectangle here.

we know that one pair of the sides (NK = LM) are 24 cm long.

and we know that KL:LM = 3:4.

that means that the pair KL = MN are the shorter sides of the rectangle. and their length is according to the ratio 3/4 of NK=LM.

3/4 × 24 = 18 cm

the area of that rectangle is therefore

18 × 24 = 432 cm²

Step-by-step explanation:

Hope this helps you!!!!!!! :D

Answer:

1.2 hours

Step-by-step explanation:

240=(110+90)t

240=200t

t=6/5

t=1.2

It will take 1.2 hours (or 1 hour and 12 minutes) for the two trains to meet.

To find how long it will take for the two trains to meet, we can use the concept of relative speed. When two objects are moving towards each other, their relative speed is the sum of their individual speeds.

Let's calculate the relative speed of the two trains:

Relative Speed = Speed of Train A + Speed of Train B

Relative Speed = 110 miles per hour + 90 miles per hour

Relative Speed = 200 miles per hour

Now, the distance between the two trains is 240 miles. To find the time it takes for them to meet, we can use the formula:

Time = Distance / Relative Speed

Time = 240 miles / 200 miles per hour

Time = 1.2 hours

So, it will take 1.2 hours (or 1 hour and 12 minutes) for the two trains to meet.

Answer:

Step-by-step explanation:

The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.

Answer:

See below

Step-by-step explanation:

The absolute value of a number is its POSITIVE distance from 0. We notate absolute value as |x|.

For example, if you wanted to determine the absolute value of -5, you would write it as |-5| which is 5.

-5 is 5 away from 0, so this confirms the answer is right.
