Answer:

B. 8 1/5

Step-by-step explanation:

To find the value of n, we need to isolate it

13+5n = 54  Subtract both sides by 13

5n = 41         Divide both sides by 5

n =  8 1/5

Answer:

11.5

Step-by-step explanation: Since there is 1.15 land miles in one nautical mile you multiply 1.15 by 10 to find how many land miles are in 10 nautical miles.

The number of land miles there in 10 nautical miles will be 11.5.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.

If and only if the number being multiplied is more than one, multiplication produces a resultant number that is significantly larger than the original number.

As per the given,

One nautical mile = 1.15 land miles

In 10 nautical miles = 1.15 x 10 = 11.5 land miles

Hence "The number of land miles there in 10 nautical miles will be 11.5".

Decimal form:2.23606797...

Step-by-step explanation:

Answer:

12√2

7√3

Step-by-step explanation:

The length of the hypotenuse of a 45°-45°-90° triangle with a leg of 12 is 12√2 and the length of longer leg is 7√3 for 30°-60°-90° triangle.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Ratio of the sides of a 45°-45°-90° triangle is 1 : 1 : √2.

That is,

If sides opposite to 45° = x, then the side opposite to 90° = √2 x

That is, length of the hypotenuse = √2 x

Given length of a leg = 12

Length of the hypotenuse = √2 × 12 = 12√2.

Ratio of the length of sides of 30°-60°-90° triangle is 1 : √3 : 2.

That is,

Length of side opposite to 30° = x

Length of side opposite to 60° = √3 x

Length of side opposite to 90° = 2x  (Hypotenuse)

We have to find the longer leg, that is √3 x.

Length of hypotenuse = 14

2x = 14 ⇒ x = 7

Length of longer leg = 7√3

Hence the lengths are 12√2 and 7√3.

Answer:

[tex] \frac { 5\sqrt{21} }{ - 7} [/tex]

Step-by-step explanation:

Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r

[tex] {7}^{2} + {24}^{2} = {r}^{2} [/tex]

49+576=

[tex] {c}^{2} [/tex]

525=c^2

[tex] \sqrt{525} = 5 \sqrt{21} [/tex]

So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals

[tex] \frac{x}{r} [/tex]

cos=

[tex] \frac{ - 7}{5 \sqrt{21} } [/tex]

then we find secant which is the reciprocal of cos so we flip the numbers and that equals

[tex] \frac{5 \sqrt{21} }{ - 7} [/tex]

Sum of [tex]\frac{9}{10}[/tex] and [tex]\frac{5}{6}[/tex] is equal to [tex]\boldsymbol{\frac{26}{15}}[/tex].

A summation, also known as a sum, is the outcome of adding numbers or quantities arithmetically. A summation always has an even number of terms.

Summation is the adding of a series of numbers known as addends or summands; the result is their sum or total.

Sum of [tex]\frac{9}{10}[/tex] and [tex]\frac{5}{6}[/tex] [tex]=\frac{9}{10} +\frac{5}{6}[/tex]

                          [tex]=\frac{27+25}{30}\\\\ =\frac{52}{30}\\\\ =\frac{26}{15}[/tex]

Therefore, sum of [tex]\frac{9}{10}[/tex] and [tex]\frac{5}{6}[/tex] is equal to [tex]\boldsymbol{\frac{26}{15}}[/tex]

Answer:

6

Step-by-step explanation:

Degree of a polynomial is the degree of the monomial with the greatest degree, which in this case is 6x^6, so the degree of this polynomial is 6 because the x is raised to the 6th degree.

The degree of the polynomial 5x⁵-6x⁶ + 2 is 6.

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given:

The polynomial,

5x⁵-6x⁶ + 2.

Here, we have the variable x.

And the highest power of a variable is a degree of a polynomial.

So, the degree of polynomial is 6.

Therefore, the degree of the polynomial is 6.
