What is the value of tan A?.

1 in 3 angle of slope in degree is 18.435°.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

An angle is a shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located.

The inverse tangent function is called arctangent, often known as arctan or tan-1. Tangent only has a limited domain for its inverse function.

So to find the 1 in 3 angle we have to put the value 1/3 in arctan function

∴ arctan (1/3) = 18.43494882° ≈ 18.435.

The slope of the equation 3x + 4y = -12 is -3/4

Slope in math is defined as the ratio of the amount that y increases as x increases some amount

Here we have given the equation 3x + 4y = -12.

As we all know that the general form of the equation of the line is written as,

y = mx + c

here m refers the slope of the line and c refers the y intercept of the line.

Now, we have to convert the given equation into the general form then it can be look like the following,

=> 4y = -12 - 3x

=> y = -12/4 - 3x/4

It can be rewritten as,

=> y = -3x/4 - 12/4

Then the resulting slope is -3/4.

The credit utilization ratio would be 11.7%.

What is credit utilization?

The credit utilization ratio is a measure of how much of a person's credit limit is being used. It is calculated by dividing the total credit card balances by the total credit limit.

In Mary's case, the total credit card balances are $150 + $200 = $350

The total credit limit is $2000 + $1000 = $3000

To find the credit utilization ratio, we divide the total credit card balances by the total credit limit:

$350 / $3000 = 0.117 or 11.7%.

Hence, the credit utilization ratio would be 11.7%.

The questions 18, 19, and 20 have the values of x for the bisected angle to be 6, 15, and 8 respectively.

If line UW bisects m∠TUV then;

m∠TUW = m∠WUV

13x - 5 = 7x + 31

13x - 7x = 31 + 5 {collect like terms}

6x = 36

x = 36/6 {divide through by 6}

x = 6

If line MO bisects m∠PMN then;

2(m∠OMN) = m∠PMN

2(2x + 7) = 74 {divide through by 2}

2x + 7 = 37

x = (37 - 7)/2 {make x the subject}

x = 15

If line EF bisects m∠CEB then;

m∠FEB = m∠CEF

10x - 3 = 7x + 21

10x - 7x = 21 + 3 {collect like terms}

3x = 24

Answer:

  28.5 m/s

Step-by-step explanation:

Given that power is 1400 W when speed is 25 m/s, and power is proportional to the square of speed, you want the speed when the power is 1820 W.

Since power is proportional to the square of speed, the ratio of speed squared to power is a constant:

  s²/P = 25²/1400 = x²/1820

where x is the unknown speed.

We can find the value of x by multiplying by 1820 and taking the square root:

  x² = 25²(1820/1400)

  x = 25√(1820/1400) = 25√1.3 ≈ 28.5 . . . . m/s

The speed is 28.5 m/s when the power is 1820 watts.

To find out how much Kim spent in total with the 8% sales tax included, we first need to add up the cost of all 4 items: $32.45 + $46.78 + $12.91 + $52.38 = $144.52

Next, we'll multiply that total cost by the sales tax rate as a decimal (8% expressed as 0.08) to find out how much tax Kim had to pay: $144.52 x 0.08 = $11.56

Finally, we'll add the total cost of the items and the tax to find out how much Kim spent in total: $144.52 + $11.56 = $156.08

This means that the solution to the equation x is 6.

An equation is a mathematical statement that expresses the relationship between two values. It typically consists of an equal sign (=) and two expressions that are related to each other. Equations are used to describe how one value depends on another, or how two values are related to each other.

To solve this equation, use the Quadratic Formula,
which states that for an equation of the form ax2 + bx + c = 0,
the solution is x = [-b ± √(b2 - 4ac)] / 2a.
Plugging in the given equation,
we have a = 5, b = -3, and c = 45.

Answer:

I think its two

Step-by-step explanation:

If I am wrong sorry

The fuel efficiency of the first car was 40.72 miles per gallon and the fuel efficiency of the second car was 14.28 miles per gallon.

The problem can be solved by using a system of equations.

We can call the fuel efficiency of the first car x and the fuel efficiency of the second car y.

From the problem, we know:

x + y = 55 (the combined fuel efficiency of the two cars is 55 miles per gallon)

We can also use the information about the amount of gas consumed and the distance has driven to set up another equation:

(30 gallons) * (x miles per gallon) + (40 gallons) * (y miles per gallon) = 1850 miles

Now we have a system of two equations with two variables (x and y):

x + y = 55

(30)x + (40)y = 1850

We can solve this system of equations using any method of solving such as substitution or elimination.

x = 55 - y

and substitute it in the second equation

(30)(55-y) + (40)y = 1850

1650 - 30y + 40y = 1850

-14y = -200

y = 14.28

x = 55 - 14.28 = 40.72

So the fuel efficiency of the first car was 40.72 miles per gallon and the fuel efficiency of the second car was 14.28 miles per gallon.

The product is 3x * 4x^(3/2) = 12x^(5/2)

How to do the product of root?

When multiplying two terms with the same base and different exponents, you can add their exponents.

For example, √(a^m) * √(a^n) = √(a^m * a^n) = √(a^(m+n)) = a^((m+n)/2)

The product of 3√(x^2) * 4√(x^3) is equal to:

12x^(5/2)

This is because when you multiply two terms with the same base, you can add their exponents:

3√(x^2) * 4√(x^3) = (3*4)√(x^(2+3/2)) = 12x^(5/2)

This is because

√(x^2) = x^(2/2) = x

√(x^3) = x^(3/2) = x^(3/2)

so we can write 3root x^2 = 3x and 4root x^3 = 4x^(3/2)
