Answer:

w= A / l

Step-by-step explanation:

A = lw

Where,

A= Area of a rectangle

l= Length of a rectangle

w= width of a rectangle

Area of a rectangle = length × width

Solve the formula(equation) for width(w).

A= lw

Divide both sides by l

A / l = lw / l

A / l = w

Width = Area of the rectangle / length of the rectangle

Example: Find the width of the rectangle with length of 6 inches and Area of 12 square inches.

A= 12 square inches

l= 6 inches

w= x inches

A= lw

w= A / l

= 12 / 6

= 2

w = 2 inches

Answer:

The length of the yard is 102

Step-by-step explanation:

If the width of the yard is 100 feet, and it's a rectangular, that means the other side of the rectangle is also equal to 100 feet. So so far we have 200 feet of the yard covered. Then we do 404-200=204. So the combined length of both the sides is 204. Since they both equal the same length, we can then do 204/2 to get 102. So one side length is 102 and the L, W, L, W of the rectangle is 102, 100, 102, 100. In other words, the rectangle is 102 by 100.

Answer:

Length of the yard = 102 ft

Step-by-step explanation:

Perimeter of the yard P = 404 ft

Width of the yard W = 100 ft

Find Length of the yard L = ?

Perimeter of a rectangular = 2L + 2W

404 = 2L + 2(100)

2L = 404 - 200

2L = 204

L = 204 / 2

L = 102 ft

Answer: e. x≠2             f. x≥-1/2

Step-by-step explanation:

Domain is basically the x value of a function.

----------------------------------------------------------------

Question e.

g(x)=5/(2-x)

First, keep in mind, the denominator of a fraction can not be zero or else it will be undefined.

Since x is in the denominator: 2-x≠0

2-x≠0

----------------------------------------------------------------

Question f

h(x)=√(2x+1)

For a standard square root, the value inside can't b negative

So 2x+1≥0

        2x≥-1

The length of line segment AC of the given triangle is; 14

Since Angle ABC and BCA are congruent, it means that they are equal.

An isosceles triangle is a triangle that has two equal sides and two equal base angles.

Now, since Angle ABC and BCA are equal, it means that the triangle is an isosceles triangle. It also means that sides AC and AB are equal. The expression becomes;

3x - 7 = 2x

3x - 2x = 7

x = 7

To determine the length of line segment AC. We will substitute x = 7 into 3x - 7. It becomes

(3 × 7) - 7

= 21 - 7 = 14

Answer: 28 dots

Step-by-step explanation: In this pattern,

we can see the the first figure is just 1 dot.

The second figure has a new row on the bottom with 2 dots.

The third figure has a new row on the bottom with 3 dots

and the fourth figure has a new row on the bottom with 4 dots.

So continuing with this pattern,

the next figure will have a new row with 5 dots,

the next will have a new row with 6 dots,

and the next will have a new row with 7 dots.

So in the 7th picture, we will have 7 + 6 + 5 + 4 + 3 + 2 + 1 dots.

This simplifies to 28 dots.

Answer:

[tex]Average = 12\frac{4}{7} \ lb[/tex]

Step-by-step explanation:

Given

Weight of sea glass

To solve this question, we have to calculate the mean of the weight of the sea glass as follows;

[tex]Average = \frac{\sum x}{n}[/tex]

Where n = number of sea glass

[tex]n = 14[/tex]

So:

[tex]Average = \frac{\sum x}{n}[/tex] becomes

[tex]Average = \frac{2 +2 + 2 + 1 + 11 +12 +12 +2 +24+22 +24 +3 +37+ 22}{14}[/tex]

[tex]Average = \frac{176}{14}[/tex]

[tex]Average = 12\frac{8}{14}[/tex]

Simplify fraction

[tex]Average = 12\frac{4}{7}[/tex]

Hence; the weight of the sea glass would be [tex]12\frac{4}{7}\ lb[/tex] when evenly distributed...

Answer: 75 minutes.

Step-by-step explanation:

Given that the line a bus arrives at the bus stop every 25 minuetes, and the line B busarrived every 15 minuetes both are at the bus stop right now.

In how many minutes will both be at the bus stop again?

We can achieve that by finding the LCM of 25 and 15

The LCM of both will be 3, 5 and 5

That is, 3 × 5 × 5 = 75 minute.

Therefore, both will be at the bus stop again in the next 75 minutes or 1 hour 15 minutes.

Answer:

An egg and cheese biscuit was $3.65.

Step-by-step explanation:

Liam's breakfast was:

[tex] P = E + C + M [/tex]

Where:

P: total price

E: egg

C: cheese biscuit

M: carton of milk  

[tex] P = E + C + M [/tex]

[tex] 5.65 = E + C + M [/tex]   (1)

Now, Finn's breakfast was:

[tex] P = E + C + 2*M [/tex]

[tex] 7.65 = E + C + 2*M [/tex]   (2)      

By subtracting equation (2) from (1) we have:

[tex] 7.65 - 5.65 = 2M - M [/tex]

[tex] M = 2 [/tex]

Hence, the price of a carton of milk is $2, so by entering this value into equation (1) we can find the price of an egg and cheese biscuit:

[tex] 5.65 = E + C + M [/tex]

[tex] 5.65 - 2 = E + C [/tex]

[tex] E + C = 3.65 [/tex]

Therefore, an egg and cheese biscuit was $3.65.

Answer:

x = -3/4 or x = 3

Step-by-step explanation:

Solve for x over the real numbers:

(-4 x - 3) (x - 3) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

-4 x - 3 = 0 or x - 3 = 0

Hint: | Look at the first equation: Divide both sides by the sign of the leading coefficient of -4 x - 3.

Multiply both sides by -1:

4 x + 3 = 0 or x - 3 = 0

Hint: | Isolate terms with x to the left hand side.

Subtract 3 from both sides:

4 x = -3 or x - 3 = 0

Hint: | Solve for x.

Divide both sides by 4:

x = -3/4 or x - 3 = 0

Hint: | Look at the second equation: Solve for x.

Add 3 to both sides:

Answer: x = -3/4 or x = 3

Answer:

lesser x = -3/4

greater x =3

Step-by-step explanation:

h(x) = (-4x – 3)(x – 3)

Set the function equal to zero to find the zeros

0 = (-4x – 3)(x – 3)

Using the zero product property

0 = (-4x – 3)   0=(x – 3)

Solve each  equation

3 = -4x          3 =x

-3/4=x            3 =x

lesser x = -3/4

greater x =3

Answer:

42,804.35 million people per miles

Step-by-step explanation:

Population density = Number of people / Land area

New York

Population = 8.55 million

Land area = 300 square miles

Manhattan

Population = 1.64 million

Land Area = 23 Square miles

Population density of New York = Number of people / Land area

= 8.55 million / 300 Square miles

= 8,550,000 / 300

= 28,500 people per square miles

Population density of Manhattan = Number of people / Land area

= 1.64 million / 23 miles

= 1,640,000 / 23

= 71,304.35 million people per square miles

Difference between Manhattan and new York City = 71,304.35 - 28,500

= 42,804.35 million people per miles

Therefore,

The population density of Manhattan is greater than that of New York City by 42,804.35 million people per miles

The difference between the population densities of Manhattan and New York is 42,804 people per square mile.

The density of New York is:

= Population / Area

= 8,550,000 / 300

= 28,500 people per square mile

Density of Manhattan:

= 1,640,000 / 23

= 71,304 people per square mile

The difference is:

= 71,304 - 28,500

= 42,804 people per square mile

In conclusion, Manhattan's population density is 42,804 people per square mile higher than New York City's.
