The length and width of the rectangle are: 10 inches and 5 inches.

Rectangle refers to a plane shape, as opposed to a square, with four straight sides and four right angles, particularly one with uneven neighboring sides.

Given:

To find: the length and width of the rectangle.

Finding:

Let the width of the rectangle be 'x'

Then the length of the rectangle = x + 5

Now, area of the rectangle = width (length)

=> 104 = x ( x + 5)

=> x² + 5x - 104 = 0

=> x² + 13x - 5x - 104 = 0

=> (x + 13) (x - 5) = 0

Since the lengths can't be negative, x = 5, i.e., the width of the rectangle = 5 inches

=> Length = 5 + 5 = 10 inches

Answer:

m = 0.5

Step-by-step explanation:

Step 1 : Take the cube root of it.

Basically what this means is that you multiply the reciprocal of it to the 0.125

Like this:

m^3 = 0.125   --------->       m = 0.125 (1/3)

Step 2: Solve

m = 0.125 (1/3)

m = 0.5

If the cost of car is $26000 and it depreciates by one half every 7 years, then the cost of car will reach to $8800 after 10 years.

Given that the cost of car is $26000 and it depreciates by one half every 7 years.

We are required to find the number of years after which the cost of car will reach $8800.

Because the method of depreciation is not given in question, so we will apply straight line method of depreciation.

Depreciation is the gradual or permanent decrease in the cost of asset due to passage of time and many factors.

Depreciation of 7 years=26000*R*7

13000=26000*R*7

R=13000/26000*7

=7.14%

The cost of car will be $8800,so the depreciation charged will be 26000-8800=$17200

17200=26000*7.14/100 *N

N=1720000/26000*7.14

=9.2652

Because it is slightly larger than 9 so we can approx it as 10 years.

Hence if the cost of car is $26000 and it depreciates by one half every 7 years, then the cost of car will reach to $8800 after 10 years.

Answer:

81.9 inches, 63.7 inches, 45.5 inches respectively

Step-by-step explanation:

Total number of units = 9+7+5 = 21

21 units = 191.1 inches

1 unit = 191.1/21 = 9.1 inches

9 units = 9.1 x 9 = 81.9 inches

7 units = 9.1 x 7 = 63.7 inches

5 units = 9.1 x 5 = 45.5 inches

Emmy's actual score in the exam is 64.

A Z-score is a metric that quantifies how closely a value relates to the mean of a set of values. Standard deviations from the mean are used to measure Z-score. A Z-score of zero means the data point's score is the same as the mean score.

Given,

class average =  76

standard deviation = 8

Z- score = -1.50

The formula of Z-score is -

z = (x-μ)/σ

Where x is the actual score,

μ is the mean,

σ is the standard deviation.

Now putting the values in the formula we get,

-1.50 = (x- 76) / 8

⇒ on solving, we get x = 64

So the actual score of Emmy = 64

The value of the expression 3x + 5y will be 47.

It should be noted that an equation is used in Mathematics to show the relationship the exist between different variables.

The given equations are:

x - 4y = -10 ...... i

2x + 9y= -3 ....... ii

Multiply equation i by 2

Multiply equation ii by 1

2x - 8y = -20 ...... iii

2x + 9y = -3. ..... iv

Subtract equation iv from iii

(2x - 2x) (-8y - 9y) = (-20 + 3)

-17y = -17

Then, we have to divide by the coefficient.

y = -17/-17

y = 1

Since x - 4y = -10.

We will then put the value of y = 1 into the equation

x - 4(1) = 10

x = 10 + 4

x = 14

Therefore, 3x + 5y will be:

=3(14) + 5(1)

= 42 + 5

= 47.

In conclusion, the value of 3x + 5y is 47.

Algebra is a universal language used in communicating ideas, and it therefore improves how people can teach or learn ideas from others

Algebra is the mathematics representation of ideas, problems, situation or solutions using mathematical expressions.

Algebra makes use of numbers, variables, and operators to give value or convey information.

Algebra is therefore an indispensable communication tool that is used in all walks of life to improve understanding of disseminated information, from the original source, to the intended destination and beyond, without, losslessly losing any substance, value or understanding.

With algebra, a doctor speaking a foreign language in a remote location can perform complex and emergency operational procedures based on guidance from another doctor communicating through the internet to his exact location and a local robot that is able translate verbal information into action based on algebraic relationships.

Algebra allows the foreign doctor to obtain or look for specific health metrics and indicators.

It allows the foreign doctor to understand the cost implications as well as to avoid dangerous situations and risk factors which are best specified by algebraic relation, that is understandable to all languages, given that it is based on numbers and variables.

Algebra therefore is one of the main means through which one person can teach another or communicate ideas.

The number of blue marbles in the jar are 8.

Given,  the total number of marbles in the jar = 24.

therefore, total number of all possible outcomes = 24.

Let the number of green marbles in Jar be x.

therefore, the number of favourable outcomes = x.

The probability that the marble drawn is green  = x/24

But we have the probability of drawing a green marble = 2/3

x/24 = 2/3

3x = 2 (24)

x = 16

Thus , the number of green marbles in the jar = 16

The number of blue marbles = 24 - 16 = 8

Step-by-step explanation:

The coordinate of A is 0. It is given that AR = 17. AR represents the distance from point A to point R. Remember that distance is always positive. So, from here we have two possibilities.

Point R is on Right side of A i.e. at coordinate 17

Point R is on Left side of A i.e. at coordinate -17

In both of these cases AR which is the distance from A to R will be 17.

So, if R is on Right side of A, the midpoint of AR would be:

0+17

  ÷      =  17/2  = 8.5

  2

Or if R is on Left side of A, the midpoint of AR would be:

0-17

  ÷      =  -17/2  = -8.5

  2

Thus, the possible coordinates of the midpoint of AR are 8.5 and -8.5

If O is the midpoint of LN and P is the midpoint of MN and if OP = 31 - 2x, and LM = 38 + 4x, then the measure of LM = 88

As per the question statement, Triangle LMN where O is the midpoint of LN and P is the midpoint of MN and if OP = 31 - 2x, and LM = 38 + 4x, we are supposed to find the measure of LM.

As O is the mid point of LN and P is the midpoint of OP the using the Mid point theorem, we can say that in Triangle LMN

[tex]OP=\frac{LM}{2}[/tex]

Substituting values,

[tex]31-2x=\frac{38+4x}{2} \\2(31-2x)=38+4x\\62-4x=38+4x \\8x = 100\\x=12.5[/tex]

LM =  38 + 4x

[tex]LM = 38 + 4(12.5)\\LM=38 + 50\\LM=88[/tex]

Hence value of LM is 88

Water main valves should be located at frequent intervals in a grid system.

The flow and temperature in pipes and plumbing fittings are controlled by water valves. The valves regulate steady flow and volume when they are correctly placed and used. Water valves are made of brass, plastic, stainless steel, bronze, cast iron, and galvanised pipe, among other materials.

The master cutoff valve for the house will typically feature a wheel (a gate valve) or a straight handle (ball valve). The wheel on gate valves (seen on the right) is turned clockwise until the water is shut off. To turn off the water, turn the handle of a ball valve a quarter turn in the opposite direction. Every house has two main water shutoff valves: one inside and one near the intersection of your property and the street.

Answer:

s = 4 m

Step-by-step explanation:

the area (A) of a square is calculated as

A = s² ( s is the side length )

given A = 16 m² , then

s² = 16 ( take square root of both sides )

s = [tex]\sqrt{16}[/tex] = 4 m

Answer:

4m

Step-by-step explanation:

All the sides of a square are equal lengths. So 2 numbers that are the same must equal 16m^2.

A number times itself is known as a square number. The value of this square number is 16 m².

It can be shown like this:

a²= 16 m² or a×a = 16 m²

The reverse of squaring numbers is square root. To find the value of one side you can do √16. √16 = 4. We can check this by substituting (replacing) 4 in the place of 'a' to see if the answer is 16.

a×a = 16 m²

4 × 4 = 16

Therefore, the length of one side of the square equals to 4m.
