write the sentence as an equation.
172 is f more than 245

Answer:

x = 35

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

x + 52 + x + 2x - 12 = 180

4x + 40 = 180 ( subtract 40 from both sides )

4x = 140 ( divide both sides by 4 )

x = 35

In a graph, the domain and the range are found as follows:

For this problem, the function is given by the following rule stated in the problem:

f(x) = (x² - 4x - 12)/(x + 2).

The graph of the function is given at the end of the answer. From it, we can see that the function unexpectedly devolves into a linear function. This is because -2 is a factor of x² - 4x - 12, hence (x² - 4x - 12) = (x + a)(x + 2), and x + 2 is simplified with the denominator.

The function is defined for all real values, and also assume all real values, hence:.

Answer:

245 + 35x = 560

Step-by-step explanation:

35 x 7 = 245 (for monday)
Then the equation should be

245 + 35x = 560

It looks like you solved it too, your answer is correct btw! Lmk if you need help with the steps, or anything

Also, how you make this equation is this, you put how much he earned for monday, and then add it to 35x (x being the amount of cars he did) make sure to do = 560 at the end so you can solve it :)

Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!

Step-by-step explanation:

Since he gets  35$ for every car he washes and washed seven cars on Monday, he got 35*7=245. Now, you can minus the amount from it to 315. 315/35 is 9, so nine is your answer.

To phrase it into an equation, you can do when x=amount of cars washed, 35x=560-7*35.

Hope this helped!

The total weight of the two animals is 1.3 x 10^4 lbs.

The given parameters are

Animal 1 = 4.23 x 103 lbs.

Animal 2 = 8.7 x 103 lbs.

Rewrite the parameters properly

Animal 1 = 4.23 x 10^3 lbs.

Animal 2 = 8.7 x 10^3 lbs.

The total weight of the two animals is calculated as

Total weight = Animal 1 + Animal 2

This gives

Total weight = 4.23 x 10^3 lbs + 8.7 x 10^3 lbs.

Factor out 10^3 lbs

Total weight = (4.23 + 8.7) x 10^3 lbs.

Evaluate the sum

Total weight = 12.93 x 10^3 lbs.

Rewrite as

Total weight = 1.293 x 10^4 lbs.

Approximate

Total weight = 1.3 x 10^4 lbs.

Hence, the total weight of the two animals is 1.3 x 10^4 lbs.

The image of the point A after the given compositions of transformation will be (5, 1).

We are given the coordinate of the point A as:

A = (1, - 3)

Now, we have to rotate it 90° about the origin.

The rule for a rotation by 90° about the origin is given by (x, y) will become (− y, x)

So, we get for point A as:

A' = (3, 1)

Now, we have:

Translation: f(x,y)=(x+2,y)

So, for point A' we get the translation as:

A" = ( 3 + 2, 1)

x=5 is the required equation of straight line

The steepness of a line is determined by its slope. The slope is m in the equation for a line that is typically used, y = mx + b. The term "rise over run" is also frequently used to describe it and describes how much the y-value changes as the x-value does.

According to the given value;

slope of line is Y₂-Y₁/X₂-X₁

hence slope for given line will be

3-(-2)/5-5 =5/0 = ∞

slope is infinity means straight line is vertical in nature and vertical lines are of the form x=a where a is some constant

now we can observe that 5 is constant in both the given points so x=5 is the required line which passes through (-2,-6),(-2,5)

Hence,x=5 is the required equation of straight line .

The standard deviation of the method is 0.7193.

Standard Deviation:

Standard deviation of a data set is the square root of the calculated variance of a set of data.

The formula for standard deviation is,

[tex]\sigma^2 = \dfrac{\Sigma (x_{i} - \mu)^2}{n}[/tex]

Where

xi is an individual value

μ is the mean/expected value

N is the total number of values

Given,

Data set:

20.0, 20.0, 20.0, 20.1, 20.2, 20.5, 20.5, 20.6, 20.7, 20.7, 21.0, 21.2, 21.5, 21.6, 22.1, 22.3

Here we need to find the standard deviation.

To find the standard deviation we have to identify the following from the given set,

They are,

Count, N: 16

Sum, Σx: 333

Mean, μ: 20.8125

Now we have to apply the values on the formula,

In order to solve it,

[tex]\sigma^2=\frac{[(20-20.8125)^2+....+(22.3-20.8125)^2]}{16}[/tex]

When we simplify it then we get,

[tex]\sigma^2=\frac{8.2775}{16}[/tex]

So,

σ = √0.51734375

σ =  0.7193

Therefore, the standard deviation is 0.7193.

The ladder needs to be 34.3m long from tree you to get to get the cat.

We must determine the hypotenuse in this right triangle, which is the side that is opposite the triangle's 90° angle. When the neighboring side is 23 meters away, the elevation angle is  54°

Suppose Hypotenuse equals h.

Given, the base is 23m

Using trigonometry,

tan θ = Base / hypotenuse

tan 54° = 23 / h

⇒ 0.67 = 23 / h

⇒ h = 23 / 0.67

⇒ h = 34.3

So, the ladder needs to be 34.3m away in order to reach cat.

The equation for the plane consisting of all points that are equidistant from the points (−7, 1, 1) and (3, 3, 5) is 20x + 4y + 8z = -9.

In order to determine the distance of this plane (x, y, z) with the given points, we would use the distance formula.

Mathematically, the distance between three (2) points that are on a coordinate plane can be calculated by using this formula:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]

For these points (x, y, z) and (−7, 1, 1), the distance is given by:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]

Distance = √[(x₂ - (-7))² + (y₂ - 1)² + (z₂ - 1)²]

Distance = √[(x₂ + 7)² + (y₂ - 1)² + (z₂ - 1)²]

By using the algebraic formulas, the expanded expression is given by:

(a - b)² = a² - b² - 2ab

(a + b)² = a² + b² + 2ab

Distance = √[(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1)]   .......equation 1.

For these points (x, y, z) and (3, 3, 5), the distance is given by:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]

Distance = √[(x - 3)² + (y - 3)² + (z - 5)²]

Distance = √[(x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)]    .....equation2.

Since both distances are equidistant, we would equate eqn. 1 and eqn. 2 and then simplify:

√[(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1)] = √[(x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)]

(x² + 14x + 49) + (y² - 2y + 1) + (z² - 2z + 1) = (x² - 6x + 9) + (y² - 6y + 9) + (z² - 10z + 25)

x² + 14x + 49 + y² - 2y + 1 + z² - 2z + 1 = x² - 6x + 9 + y² - 6y + 9 + z² - 10z + 25

14x + 6x - 2y + 6y - 2z + 10z + 52 - 43 = 0

20x + 4y + 8z + 9 = 0
