Answer:

Median = 18

Step-by-step explanation:

The median is the middle number if the elements (prices)  are arranged from least to greatest.

let's arrange the prices of watches from least to greatest:

12, 15, 16, 16, 20, 22, 24 27

Since there are even number of numbers (8), the median is the value between 4th and 5th numbers.

4th number is 16

5th number is 20

We need the value between 16 and 20. We get that by adding these 2 and dividing by 2:

16 + 20 = 36

36/2 = 18

THus, median = 18

Answer:

Area of square= 216 square inches

Perimeter  of square [tex]= 24\sqrt{6}[/tex] inches.

Step-by-step explanation:

Given that length of the side of the square = [tex]6\sqrt{6}[/tex] inches.

Now we need to find area of the rectangle. So apply the formula  area of rectangle

[tex]Area of square= (side)^2[/tex]

[tex]Area of square= (6\sqrt{6})^2[/tex]

[tex]Area of square= 6^2(\sqrt{6})^2[/tex]

[tex]Area of square= 36(6)[/tex]

Area of square= 216 square inches

Similarly

[tex]Perimeter of square= 4(side)[/tex]

[tex]Perimeter  of square= 4(6\sqrt{6})[/tex]

Perimeter  of square [tex]= 24\sqrt{6}[/tex] inches.

Answer:

Step-by-step explanation:

First, you need to make these conversions:

(Remember that [tex]1m=100cm[/tex])

4,000 cm to m:

[tex](4,000cm)(\frac{1m}{100cm})=40m[/tex]

700 cm to m:

[tex](700cm)(\frac{1m}{100cm})=7m[/tex]

You can observe in the figure that it is formed by  two rectangles and a semi-circle.

To calculate the perimeter, you need to add the exterior measures of each figure.

Remember that the circumference of a circle is:

[tex]C=2\pi r[/tex]

Where "r" is the radius

Therefore, the perimeter is:

[tex]P=34m+7m+10m+40m+10m+68m+33m+\frac{(2\pi (17m)}{2}\\P=255.40m[/tex]

To find the area of the indoor sports exhibition, you need to add the areas of the rectangles and the area of the semi-circle.

The area of a rectangle can be calculated with:

[tex]A_r=lw[/tex]

Where "l" is the lenght and "w" is the width.

The area of a semi-circle can be calculated with:

[tex]A_{sc}=\frac{\pi r^2}{2}[/tex]

Where "r" is the radius.

Then, the area of the indoor sports exhibition  is:

[tex]A=(40m)(10m)+(68m)(33m)+\frac{\pi (17m)^2}{2}\\A=3,097.96m^2[/tex]

Answer:

x= 4-7i  x= 4+ 7i

Step-by-step explanation:

step 1 : make equation = 0

[tex]x^{2}[/tex] - 8x + 65 = 0

step 2 : solve for x [ using the quadratic equation]

ie :     x = -b ± [tex]\sqrt{b^{2}-4ac}[/tex] / 2a

so it will look like this

x= -(-8) ± [tex]\sqrt{(-8)^{2} - 4(1)(65)}[/tex] /2(1)

when you simplify you wont be able to root the -196 so you will have to separate the roots

x = 8 ±( [tex]\sqrt{-1}[/tex] )( [tex]\sqrt{196}[/tex]) / 2

now there is a rule for negative roots whereby  [tex]\sqrt{-1}[/tex] is equivalent to i so now you will change [tex]\sqrt{-1}[/tex] into i

Simplify [tex]\sqrt{196}[/tex]

which will give you 14

now place all the new values into the formula

8 ± 14i /2

you can then further simplify to  

4 ± 7i

step 3 : separate

this will give you the final answer of

x= 4 + 7i   x= 4- 7i

Answer:

x = 4+7i and x=4-7i

To solve the problem, we need to remember how Absolute Value Functions behave, when we have this type of function, related to an inequality, the solution will be between two values.

We are given the inequality:

[tex]|x|<5[/tex]

So, we know that "x" will be between -5 and 5:

[tex]-5<x<5[/tex]

Hence, the solution of the given inequality will be:

(-5,5) or {-5<x<5}

Step-by-step explanation:

Answer:

x is 12

Step-by-step explanation:

Write a proportion

4:5

x:15

or you can write it as 4/5=x/15

Cross multiply and you get 12  

The value of x if the scale factor of figure A to figure B is 4:5 is; x = 12

We are given the scale factor of figure A to figure B as 4:5.

Now, looking at both triangles, we can say that;

x:15 = 4:5

Thus,we can write in fraction as;

x/15 = 4/5

x = 15 × 4/5

x = 12

In conclusion, the value of x from the given proportion between both triangles is 12.

To simplify the expression -(5-3v) using the distributive property, distribute the negative sign to each term inside the parentheses and combine like terms.

To simplify the expression -(5-3v) using the distributive property, we need to distribute the negative sign to each term inside the parentheses. This means we will multiply -1 by both 5 and -3v.

The distributive property states that for any numbers a, b, and c, a(b + c) is equal to ab + ac. Applying this property to our expression, we get -(5) - (-3v), which simplifies to -5 + 3v.

Therefore, the simplified expression is -5 + 3v.

Answer:

Area of the parking lot = 6525 ft²

Explanation:

Since the two isosceles right-angled triangles have equal bases and heights, therefore, their areas are equal

Therefore:

Area of the parking lot = area of rectangle + 2*area of isosceles triangles

1- getting the area of the rectangle:

Area of rectangle = length * width

We are given that the dimensions of the rectangle are 45 ft and 100 ft

Therefore:

Area of rectangle = 45 * 100 = 4,500 ft²

2- getting the area of the isosceles triangle:

Area of triangle = 0.5 * base * height

From the drawing, we can note that:

base of triangle = height of triangle = smaller side of the rectangle = 45 ft

Therefore:

Area of triangle = 0.5 * 45 * 45 = 1,012.5 ft²

3- getting the total area:

Total area of parking lot = area of rectangle + 2*area of isosceles triangles

Total area of parking lot = 4500 + 2(1012.5)

Total area of parking lot = 6,525 ft²

What is Proportion

A proportion is an equation stating that two rational expressions are equal. Simple proportions can be solved by applying the cross products rule.

If [tex]\frac{a}{b} = \frac{c}{d}[/tex] then ab = bc.

What is Direct variation?

The phrase “ y varies directly as x” or “ y is directly proportional to x” means that as x gets bigger, so does y, and as x gets smaller, so does y. That concept can be translated in two ways.

[tex]\frac{y}{x} = k[/tex] for some constant k.

The k is called the constant of proportionality. This translation is used when the constant is the desired result.

What is Inverse Proportion?

According to the expressions "y varies inversely as x" and "y is inversely proportionate to x," y decreases as x increases or vice versa. There are two translations for this idea. For any constant k, referred to as the constant of proportionality, yx = k. If the constant is wanted, use this translation.

What is Joint Variation?

Joint variation is the term used to describe when one variable changes as the sum of other variables. There are two translations for the phrase "y fluctuates concurrently as x and z."

Answer: 12.5 tomatoes

Step-by-step explanation:

You know that the recipe for 4 servings requires 5 tomatoes and you want to make chili for 10 servings. Therefore, to calculate the amount of tomatoes required for this, you should use the following conversion factor:

[tex]\frac{5\ tomatoes}{4\ servings}[/tex]

Now multiply the conversion factor by the 10 servings:

[tex]=(10\ servings)(\frac{5\ tomatoes}{4\ servings})\\=12.5\ tomatoes[/tex]

Therefore, you will use 12.5 tomatoes to make 10 servings.

Answer:

Tomatoes for 10-servings = 12.5

Step-by-step explanation:

Given

Number of tomatoes for 4 servings = 5

So we can calculate the number of tomatoes for one serving by dividing the serving by number of tomatoes.

So,

Number of tomato for one serving = 5/4

= 1.25

Now we can calculate the number of tomatoes for 10 servings

Number of tomatoes for 10 servings = Number of tomatoes for one serving * 10

= 1.25 * 10

= 12.5 tomatoes

[tex]2x = 344 - 54[/tex]

[tex]2x=290[/tex]

[tex]x = 145[/tex]
