1. Find n.
2 ft
Area = 28 sq ft

Answers

Answer 1

Answer:

n=14

Step-by-step explanation:

do 28/2=14

Answer 2

The value of n is 14 when area is 28 square feet.

What is Area of Rectangle?

The area of Rectangle is length times of width.

The formula for the area of a rectangle is

Area = length × width

The width = 2ft and

the area = 28 sq ft.

So, we can write the above equation as

28 = n×2

2n = 28

Divide both sides by 2.

n=14

Hence, the value of n is 14 when area is 28 square feet.

PLEASE HELP, WILL MARK BRAINLIEST!! The diagram shows the dimensions of a deck. A student finds the area by adding 16 ft2 + 48 ft2. Is the student correct? Explain your reasoning.

Answers

Answer:

The student is wrong, the total area = 16 ft² + 20 ft²

Step-by-step explanation:

The figure can be consists of :

1) A square of side length of 4 ft

2) A trapezoid of height (8-4 = 4 ft) and the bases length is (6 and 4 ft)

So,

The area of the square = 4 * 4 = 16 ft²

The area of the trapezoid = 0.5 (6+4) * 4 = 5 * 4 = 20 ft²

So ,the total area = 16 + 20 = 36 ft²

So,

The student is distracted.

he have found the area of total rectangle of length of 8 ft and width of 6 ft instead of the area of the trapezoid.

So, the student is wrong

Which answer is correct?

Answers

Well, since the graph starts at (0,50), making our y-intercept 50, we can knock off D as an option.

The next step is to find the slope. To do this, find two points and subtract the y values over the x values. (Just make sure that whichever y value you start with - start with the same x value).

So we have >>> (50, 200) and (0,50) from earlier.

200 - 50 / 50 - 0 = 150/50 or 3/1, or 3.

This makes the correct answer A since the equation is represented as y = mx + b, where m is the slope and m has a value of 3.

Use the quadratic formula to solve x2 - 5x - 2 = 0.​

Answers

Answer:

x=-0.37 or 5.37

Step-by-step explanation:

The quadratic formula is;

[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]

The expression to be solved is

[tex] {x}^{2} - 5x - 2 = 0[/tex]

Comparing this to the general form of the quadratic equation,

[tex] a{x}^{2} + bx + c = 0 [/tex]

a=1, b=-5 and c =-2.

We substitute these values into the quadratic formula

[tex] \implies x = \frac{ - ( - 5)\pm \sqrt{ { (- 5)}^{2} - 4(1)( - 2)} }{2(1)} [/tex]

Simplifying we obtain,

[tex] x = \frac{ 5\pm \sqrt{25 + 8}}{2} [/tex]

[tex] \implies x = \frac{ 5\pm \sqrt{28}}{2} [/tex]

[tex] \implies x = \frac{5 + 2\sqrt{7} }{2}or \frac{5 - 2 \sqrt{7} }{2} [/tex]

[tex]\implies x = \frac{5}{2} + \sqrt{7} or \frac{5 }{2} - \sqrt{7} [/tex]

x=5.37 or -0.37

The solutions to the quadratic equation x² - 5x - 2 = 0 are:

x = (5 + √33) / 2

x = (5 - √33) / 2

To solve the quadratic equation x² - 5x - 2 = 0 using the quadratic formula, we can use the formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this equation, a, b, and c represent the coefficients of the quadratic equation.

For the equation x² - 5x - 2 = 0, we can identify the values of a, b, and c:

a = 1

b = -5

c = -2

Substituting these values into the quadratic formula, we have:

x = (-(-5) ± √((-5)² - 4 × 1 × (-2))) / (2 × 1)

Simplifying:

x = (5 ± √(25 + 8)) / 2

x = (5 ± √33) / 2

Therefore, the solutions to the quadratic equation x² - 5x - 2 = 0 are:

x = (5 + √33) / 2

x = (5 - √33) / 2

No, it is a linear function.

Step-by-step explanation:

Let's select values for X, and find the corresponding Y values:

X = -3, Y = 8.5

X = -2, Y = 7

X = 0, Y = 4

X = 1, Y = 2.5

X = 2, Y = 1

X = 3, Y = -0.5

So our coordinates are:

Answers

The answer is 4x10^14 because there are 14 zeros in front of the four thus you do 4x10^(number of zeros) and thus you get 4x10^14

The frequency of red light is 4 x 10¹⁴ Hz. The correct answer is option D.

What is the Scientific Notation?

Scientific Notation is a way of writing down in the easy form of very large or very small numbers.

The given that when the frequency of an electromagnetic wave is 400,000,000,000,000 Hz, it results in red light.

The choices given are in scientific notation form, where the coefficient is multiplied by 10 raised to a certain power of 10.

To convert 400,000,000,000,000 Hz into scientific notation, we need to move the decimal point 14 places to the left to obtain a coefficient between 1 and 10.

This gives us 4.0 as the coefficient, and since we moved the decimal point 14 places to the left, the power of 10 is -14.

Therefore, the frequency of red light is 4 x 10¹⁴ Hz.

Gigi spent 12% of her birthday money on a new pair of sunglasses. What fraction of her birthday money did she spend in the new sunglasses

Answers

Answer:

3/25

Step-by-step explanation:

You know that percent is out of 100, so that's 12/100

Then simplify the fraction to 6/50 then 3/25

Final answer:

Gigi spent 12% of her birthday money on sunglasses, which is equivalent to 3/25 of her birthday money when converted and simplified from a percentage to a fraction.

Explanation:

Gigi spent 12% of her birthday money on a new pair of sunglasses. To find out what fraction of her birthday money this represents, we convert the percentage to a fraction. Percent means 'per hundred,' so 12% can be written as 12 per 100 or, more simply, 12/100. However, this fraction can be simplified further. Both the numerator (12) and the denominator (100) can be divided by their greatest common divisor, which is 4. Dividing both by 4, we get 3/25. Therefore, Gigi spent 3/25 of her birthday money on the new sunglasses.

Four CDs and 4 DVDs cost $164. The cost of the 4 CDs is half the cost of the
4 DVDs. What is the cost of each CD?

Answers

Answer:

$13.67

Step-by-step explanation:

Let's say that CD= c and DVDs= d. Four CDs and 4 DVDs cost $164, so the equation will be:

i.  4c + 4d= 164

The cost of the 4 CDs is half the cost of the  4 DVDs, to put into an equation it will be:

ii.   4c= 0.5(4d)

     4c= 2d

     d= 2c

Then we can substitute the second equation (ii) into the first equation (i). The calculation will be:

4c + 4d= 164

4c + 4(2c)= 164

4c+ 8c= 164

12c= 164

c=13.67

The cost for each CD is $13.67

Answers

Answer:

791.2 ft

Step-by-step explanation:

The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.

[tex]H=\sqrt {x^{2}+y^{2}}[/tex]

where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then

[tex]H=\sqrt {740^{2}+280^{2}}=791.20161779409930627669981858168023442712 ft\approx 791.2 ft[/tex]

Answer:

791.2 ft to the nearest tenth.

Step-by-step explanation:

From the diagram,we assume :

AD to be the height of the first cliff

BC to be the height of the second cliff

DC to be the length of the cable between the top of the two cliff.

AD=740 ft.

DE= 280 ft.

Using Pythagorean Theorem, we obtain.;

[tex] {DE}^{2}+ {CE}^{2} = {DC}^{2} [/tex]

By substitution we obtain

[tex] {280}^{2} + {740}^{2} = [/tex]

[tex] \implies78400 + 547600 = {DC}^{2} [/tex]

[tex]\implies626000= {DC}^{2} [/tex]

Taking positive square root.

Line v has a slope of -5/2
Line w is parallel to line v. What is the slope of line w?
Simplify your answer and write it as a proper fraction, improper fraction, or integer,

Answers

Answer:

-5/2

Step-by-step explanation:

Since they are both parallel they have the same rate of change. this means they have the same slope

Final answer:

Since line w is parallel to line v, which has a slope of -5/2, the slope of line w is also -5/2.

Explanation:

When two lines are parallel, they have the same slope. In this case, the slope of line w will be the same as the slope of line v.

Therefore, the slope of line w is -5/2.

The question asks about the slope of two parallel lines. By definition, parallel lines have the same slope. Given that line v has a slope of -5/2, and line w is parallel to line v, the slope of line w must also be -5/2. Therefore, line w, being parallel to line v, has a slope of -5/2.
