What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the expression be A = (2/5)^2 • 100 ÷ 2/3 + [2^4 ÷ (13 - 5)]

Now , on simplifying the equation , we get

A = ( 2/5 )² x 100 / ( 2/3 ) + [ 2⁴ / 8 ]

A = ( 4/25 ) x ( 100 x 3 ) / 2 + 2

So , the equation will be

A = 4/25 x ( 300/2 ) + 2

A = 4/25 x 150 + 2

A = 4 x 6 + 2

A = 24 + 2

A = 26

Therefore , the value of A is 26

Hence , The value of the numerical expression is 26

Answer:

2.67 ounce of cashews are in the mix.

Step-by-step explanation:

Since we are dealing with a 32 ounce bag of mixed nuts and 1/12 of this bag is cashews (1/12 of the mix),

Then:

1/12 × 32 ounce = The actual quantity of cashew nuts in the mix.

= 1/12 × 32

= 32/12

= 2.67 ounce of cashews are in the bag.

Answer:

2.666ounce is contained in the bag

Step-by-step explanation:

Given that 32 ounce of bag has mixed nuts of which 1/12 of this bag contain cashews.

(1/12 of the entire mix),

Hence,

1/12 × 32 ounce

= 1/12 × 32

= 32/12

= 2.666ounce of cashews are in the bag.

Answer:

Step-by-step explanation:

The distance of point A from the top of the pole that will make the pole be  perpendicular position to the ground

so, for the pole to be in perpendicular position it must obey Pythagorean theorem

Then, using Pythagoras theorem

c² = a² + b²

x² = 10² + 6²

x² = 100 + 36

x² = 136

x = √136

x = 11.662ft

To nearest tenth

x = 11.7 ft.

So, the pole must be at a distance of 11.7 ft from the top of the pole to point A.

To justify,

10 font long board and an 18 foot long board. To make the ramp right triangle. How long should ramp

So, to calculate the ramp, which is the hypotenuse we will still apply Pythagorean theorem

Then, using Pythagoras theorem

c² = a² + b²

x² = 10² + 18²

x² = 100 + 324

x² = 424

x = √424

x = 20.59 ft

To nearest tenth

x = 20.6 ft.

So, the ramp is 20.6 ft long

Jalen needs to measure 8 feet from point A to the base of the pole to set it perpendicularly to the ground.

To make the pole perpendicular to the ground, Jalen needs to measure the distance from point A to the base of the pole, which forms a right angle at point B.

Using the Pythagorean theorem: Distance AB = √((10)^2 - (6)^2) = √(100 - 36) = √64 = 8 feet.

Therefore, Jalen needs to measure 8 feet from point A to the base of the pole for it to be positioned perpendicularly.

Answer:

$45,000

Step-by-step explanation:

Let Kevin's Salary=x

Ethan's Salary=$34,200.

Since Ethan is earning a salary that is 28% lower than the salary of Kevin.

Ethan is earning (100-24)%=76% of Kevin's Salary.

76% of Kevin's Salary=$34,200.

0.76x=34200

Divide both sides by 0.76

x=45000

Kevin's Salary is $45,000.

Final answer:

To solve the system of equations, you can substitute the value of y in terms of x from the third equation into the first two equations.

Explanation:

The system of equations given is:

Y = ½x + 1

Y = -½x - x + 1

y = x - 1

To solve these equations, we can substitute the value of y in terms of x from the third equation into the first two equations:

Substituting y = x - 1 into Y = ½x + 1:

Y = ½(x - 1) + 1

Simplifying, we get:

Y = ½x - ½ + 1

Substituting y = x - 1 into Y = -½x - x + 1:

Y = -½(x - 1) - (x - 1) + 1

Simplifying, we get:

Y = -½x + ½ + 1

Therefore, the system of equations can be simplified to:

Y = ½x - ½ + 1

Y = -½x + ½ + 1

Given:

In ΔPQR, ∠Q = 90°

PQ = 8 cm

QR = 15 cm and

PR = 17 cm

To find the value of ∠P.

Formula

By Trigonometric ratio we get,

[tex]tan \theta=\frac{opp}{adj}[/tex]

Now let us take ∠P = θ

With respect to θ, QR be the opposite side and PQ be the adjacent side.

So,

tan θ = [tex]\frac{QR}{PQ}[/tex]

tan θ = [tex]\frac{15}{8}[/tex]

θ = [tex]tan^{-1} (\frac{15}{8} )[/tex]

θ = 61.93° (approx)

Hence, the value of ∠P is 61.93° (approx).

Answer:

61.93°

Step-by-step explanation:

Using cosine law:

15² = 8² + 17² - 2(8)(17)cosP

225 = 353 - 272cosP

cosP = 8/17

P = 61.92751306

Answer:

Median = 42  pounds

Step-by-step explanation:

It is given that the following are the weights,in pounds, of some dogs at a kennel: 36,45,29,39,51,49.

Arrange the data in ascending order.

29, 36, 39, 45, 49, 51

Total number of terms = 6 (even)

So, the formula for median is

[tex]Median=\dfrac{\frac{n}{2}\text{th term}+(\frac{n}{2}+1)\text{th term}}{2}[/tex]

[tex]Median=\dfrac{\frac{6}{2}\text{th term}+(\frac{6}{2}+1)\text{th term}}{2}[/tex]

[tex]Median=\dfrac{3\text{rd term}+4\text{th term}}{2}[/tex]

[tex]Median=\dfrac{39+45}{2}[/tex]

[tex]Median=42[/tex]

Hence, the median weight is 42 pounds.

To find the median, units of the data should be same. If one of the weights were given in kilograms, then we cannot find median.

Area of base = 1.2 m²

Number of gold fish = 6

Density of the tank should be = 4 fish/m³

Height of the tank= ?

4 fish = 1 m³

6 fish = 1.5 m³

Volume required for 6 fish is 1.5 m³

V = area of base x height

1.5 = 1.2 x h

h = 1.25 m

Hence, height of the tank is equal to 1.25 m.

  y = 1/8(x -2)^2 -1

Step-by-step explanation:

The vertex form of the equation of a parabola can be written as ...

  y = (1/(4p))(x -h)^2 +k

for vertex (h, k) and vertex-to-directrix distance p. Here, the vertex has a y-value of -1, and the directrix has a y-value of -3, so the distance between them is -1 -(-3) = 2, and the desired equation with vertex (2, -1) is ...

  y = 1/8(x -2)^2 -1

_____

Comment on the graph

One description of a parabola is that it is the locus of points equidistant from the focus and the directrix. I like to show that a point on the parabola (not the vertex) meets that requirement. That is what the dashed orange lines are for in the diagram. You can easily see that each has length 4.

Bethanie and Laney walked a total of = 0.66 miles or ([tex]\frac{33}{50}[/tex]th of a mile)

Step-by-step explanation:

Bethanie walked 3/10th of a mile

Laney walked 36/100th of a mile

Lets divide and convert them to decimal:

3 divided by 10 gives us 0.30

36 divided by 100 gives 0.36

Total they walked:

0.30 + 0.36 = 0.66 miles

Answer:

30.10

Step-by-step explanation:

Approximately 95.44% of people take between 123 and 171 minutes to read the book.

To find the percentage of people who take between 123 and 171 minutes to read the book, we'll use the properties of the normal distribution.

First, we need to find the z-scores for both 123 and 171 minutes using the formula:

[tex]\[ z = \frac{{X - \mu}}{{\sigma}} \][/tex]

Where:

-[tex]\( X \)[/tex] is the value (in minutes),

-[tex]\( \mu \)[/tex] is the mean (147 minutes),

- [tex]\( \sigma \)[/tex] is the standard deviation (12 minutes).

For 123 minutes:

[tex]\[ z_1 = \frac{{123 - 147}}{{12}} = -2 \][/tex]

For 171 minutes:

[tex]\[ z_2 = \frac{{171 - 147}}{{12}} = 2 \][/tex]

Now, we'll use a standard normal distribution table or calculator to find the percentage of values between these z-scores. For a standard normal distribution, approximately 95.44% of the data falls within ±2 standard deviations from the mean.

So, to find the percentage of people who take between 123 and 171 minutes, we subtract the percentage outside this range from 100%:

[tex]\[ \% = 100 - (100 - 95.44) = 95.44\% \][/tex]

Approximately 95.44% of people take between 123 and 171 minutes to read the book.

Answer:

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 2.3% into a decimal:

2.3% -> [tex]\frac{2.3}{100}[/tex] -> 0.023

Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:

[tex]A=65,000(1+\frac{0.023}{12})^{12(15)}[/tex]

[tex]A=91,749.04[/tex]

You will have $91,749.04 in 15 years.
