The perimeter of the quadrilateral GHJK is 24(1+√2) which can be by using the radius of the circle, 6cm.

Perimeter is the total length of the outside boundary of any two-dimensional shape. Perimeter is calculated by adding up the length of each side of a shape.

In order to calculate the perimeter of the quadrilateral, we need to first find the length of the sides.

We can do this by using the radius of the circle, r.

The side GH is equal to r+r=2r.

The side HK is equal to (r+r)√2=2r√2.

The side JK is equal to (r+r)√2=2r√2.

And the side GJ is equal to 2r.

Now that we have the lengths of the sides, we can calculate the perimeter of the quadrilateral.

The perimeter is equal to the sum of the four sides=

2r + 2r√2 + 2r√2 + 2r

= 4r+4r√2

= 4r(1+√2)

=4*6(1+√2)

=24(1+√2)

Therefore, the perimeter of the quadrilateral GHJK is 24(1+√2).

The perimeter of the square GHJK is 48cm which can be by using the radius of the circle, 6cm.

Perimeter is the total length of the outside boundary of any two-dimensional shape. Perimeter is calculated by adding up the length of each side of a shape.

In order to calculate the perimeter of the quadrilateral, we need to first find the diameter of the circle.

We can do this by using the radius of the circle, r=6cm.

So, diameter= 2*6

=12cm

As the quadrilateral is enclosing the circle, it must be a square.

So, now the length of the sides of the square= diameter of the circle.

which is 12cm.

A square has  4 equal sides. Thus the perimeter of the quadrilateral which is a square

=4*12cm

=48cm

Therefore, the perimeter of the quadrilateral GHJK is 48cm.

The link between the base price and the selling price with the markup is expressed differently in both equations, but they are both true and accurately depict the same scenario using the distributive property.

A basic tenet of mathematics is the distributive property of multiplication over addition, which asserts that the product of a number and a sum is equal to the total of the products of the number and each addend. In other words, if a, b, and c are all real numbers, then a(b + c) = ab + ac. By factoring out common components, this characteristic is employed in algebra to simplify statements and resolve equations.

This inequality states that the total cost of buying x gumballs and y jawbreakers must be less than or equal to $3.00.

Let x be the number of gumballs that Bob buys, and let y be the number of jawbreakers that Bob buys.

The cost of buying x gumballs is $0.50 times x, or 0.50x. The cost of buying y jawbreakers is $0.30 times y, or 0.30y.

Bob has $3.00 to spend on candy, so we can write an inequality to represent the total cost of buying both types of candy:

0.50x + 0.30y ≤ 3.00

This inequality states that the total cost of buying x gumballs and y jawbreakers must be less than or equal to $3.00.

Note that this inequality assumes that Bob spends all of his money on candy. If Bob wants to save some money or spend it on something else, the inequality would need to be modified accordingly.

The solution of the absolute inequality is x < -9 or x > 1

Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.

Absolute inequalities are inequalities  that involve algebraic expressions with absolute value symbols and inequality symbols.

Therefore, let's solve the absolute inequality as follows:

|2x + 8| > 10

2x + 8 > 10 or 2x + 8 < - 10

Let's solve them individually,

2x + 8 > 10

2x > 10 - 8

2x > 2

x > 2 / 2

Answer:

B) 2

Step-by-step explanation:

First, we need to find BD:

by the Pythagorean theorem, (sqrt13)^2 + (sqrt23)^2 = BD^2

we can simplify this to 13+23=BD^2, which means BD^2 = 36, and BD is 6.

Therefore to find BC, we can use the Pythagorean theorem again and create the formula:

(4sqrt2)^2 + BC^2 = 6^2

This simplifies to 32 + BC^2 = 36, which means that BC^2 = 4, and BC = 2.

If the car's wheels revolve 10,000 times without slipping, the car will travel approximately 9.92 miles.

The circumference of a circle (which is the distance around it) is given by the formula:

C = πd, where d is the diameter of the circle.

In this case, the diameter of the car's wheels is 20 in., so the circumference of each wheel is:

C = πd

C= π(20 in.) =

C = 20π in.

If the car's wheels revolve 10,000 times without slipping, then the total distance the car travels is:

distance = number of revolutions × circumference

distance = 10,000 × (20π in.)

To convert this distance to miles, we need to divide by the number of inches in a mile, which is 63,360 in.

distance = (10,000 × 20π in.) / 63,360 in./mi

distance = 9.92 miles

Therefore, distance traveled by the car is 9.92 miles.

Answer: Table 3

Step-by-step explanation:

exponential relationship means the y value is increasing/decreasing exponentially

In table 1: the value of y is NOT increasing/decreasing exponentially as 2 is being added continuously (linear), so not table 1

In table 2: the value of y is NOT increasing/decreasing exponentially as 4 is being subtracted continuously (linear), so not table 2

In table 3: the value of y IS increasing exponentially as the y variable is multiplied by 2, so table 3

In table 4: the value of y is NOT increasing exponentially as the y variable is only being increased by 5 constantly (linear), so not 4

Answer: They are not

To be linear it needs to be a diagonal arrow across. Most of these don't follow that rule, therefore it is not linear.

The cylinder has a radius of 2 times the square root of 5 meters, or roughly 4.5 meters rounded to the nearest tenth.

The formula for the volume of a cylinder is:

V = πr²h

where V is the volume, r is the radius, and h is the height.

In this case, we have:

V = 160π m³

h = 8 m

Substituting these values into the formula, we get:

160π = πr²(8)

Simplifying the equation by canceling out π on both sides, we get:

160 = 8r²

Dividing both sides by 8, we get:

20 = r²

Taking the square root of both sides, we get:

r = √20

Simplifying the radical by factoring out 4, we get:

r = 2√5

To express the radius as a decimal rounded to the nearest tenth, we can use a calculator to get:

r ≈ 4.5

Therefore, the radius of the cylinder is 2√5 meters or approximately 4.5 meters to the nearest tenth.

Answer:

Step-by-step explanation:

Given equations,

→ x - y = 5

→ 4x + y = 10

Now we have to,

→ Find the required value of x and y.

Let's solve for the value of x,

→ (x - y) + (4x + y) = (5) + (10)

→ x + 4x - y + y = 5 + 10

→ 5x + 0 = 15

→ 5x = 15

→ x = 15/5

→ [ x = 3 ]

Then the value of y will be,

→ 4x + y = 10

→ 4(3) + y = 10

→ 12 + y = 10

→ y = 10 - 12

→ [ y = -2 ]

Hence, the value of y is -2.

We would see a logarithmic sequence of values if we plotted the amount of time Edna spends watching TV weekly on a logarithmic scale.

If we plot the amount of time Edna spends watching TV on a logarithmic scale, we would see a continuous sequence of values that increase as her viewing time increases. Specifically, the sequence would be a logarithmic scale of the number of hours she watches TV per week.

On a logarithmic scale, each increment corresponds to a multiplication by a constant value. For example, if we use a logarithmic scale base 10, then each increment of 1 corresponds to a multiplication by 10. So, if we plot Edna's TV watching time on a logarithmic scale, we would see a sequence of values that increase by a factor of 10 as her TV watching time increases by an order of magnitude.

For example, if Edna watches 2 hours of TV per week, the logarithmic value would be log(2) = 0.3. If she watches 7 hours per week, the logarithmic value would be log(7) = 0.85. If she watches 20 hours per week, the logarithmic value would be log(20) = 1.3. As her viewing time increases, the logarithmic values would continue to increase in a continuous sequence.

Therefore, if we plotted the amount of time Edna watches TV each week on a logarithmic scale, we would see a logarithmic sequence of numbers.

The inner surface area of the vessel, given the diameter of the hemisphere and the total height, is 133π cm².

To find the inner surface area of the vessel, we will consider the hemisphere and the cylinder separately, and then sum their inner surface areas.

Hemisphere:

The diameter of the hemisphere is 14 cm, so its radius (r1) is half of that:

r1 = 14 cm / 2 = 7 cm

Inner surface area (hemisphere) = 2 * π * r1² / 2 = π * r1² = π * (7 cm)² = 49π cm²

The radius of the cylinder is the same as the hemisphere's (r2 = r1 = 7 cm). The height (h) of the cylinder can be found by subtracting the height of the hemisphere from the total height of the vessel:

h = total height - hemisphere height = 13 cm - 7 cm = 6 cm

Inner surface area (cylinder) = 2 x π x r2 x h = 2 x π x (7 cm) x (6 cm) = 84π cm²

Total inner surface area = inner surface area (hemisphere) + inner surface area (cylinder)

Total inner surface area = 49π cm² + 84π cm² = 133π cm²

California has the larger population, and it is approximately 20 times larger than Nebraska's population.

The population of California is 3.8 million, while the population of Nebraska is 1.9 million. To find the difference between the two populations, we can calculate 3.8 million minus 1.9 million, which equals 1.9 million. To find the ratio, we can divide the population of California by the population of Nebraska, which is 3.8 million divided by 1.9 million, which equals 2. Thus, California has a population that is 20 times larger than the population of Nebraska.

As per the given commission, the sales price of the property is $405,000.

To do this, we need to break down the commission earned by the agent into two parts: the commission earned on the first $300,000 and the commission earned on the remaining amount. The commission earned on the first $300,000 can be calculated as:

Commission on first $300,000 = 6% of $300,000

Commission on first $300,000 = 0.06 x $300,000

Commission on first $300,000 = $18,000

So, the remaining commission earned by the agent on the amount that exceeds $300,000 is:

Total commission - Commission on first $300,000 = $21,150 - $18,000

Total commission - Commission on first $300,000 = $3,150

Now, we know that the commission earned on the remaining amount is 3% of the sales price that exceeds $300,000. Let's assume the sales price of the property is x. Then we can write the following equation:

3% of (x - $300,000) = $3,150

We can simplify this equation as follows:

0.03(x - $300,000) = $3,150

x - $300,000 = $3,150 / 0.03

x - $300,000 = $105,000

x = $300,000 + $105,000
