The length if the tunnel is 460 miles. if 1 inch represents 60 miles, what is the length of the tunnel?

Answer:

19°

Step-by-step explanation:

The angle that measures 114° is equal to (6x)°

From here divide 114 ÷ 6 = 19

x = 19

Hope this helps!

Answer:

B Cos 3/25

Explanation:

X is the missing angle. From X the opposite side is the bottom of the triangle, and the adjacent is 3. Since Cos is the adjacent over the hypotenuse, the answer is Cos 3/25

Answer:

8x + 9

Step-by-step explanation:

Treat the question as 2 separate brackets

First expand 3(2x + 1) :

6x + 3

Then expand 2(x + 3) :

2x + 6

Now add the two answers together and simplify :

= 6x + 3 + 2x + 6

= 8x + 9

25% are purebred

Step-by-step explanation:

7 out of 28 dogs are purebred

7  x 10 = 70

28 x 10 = 280

70 / 280 = 2.5 / 10 = 25 / 100 = 25%

Answer:

The number is  48

Step-by-step explanation:

First, let's call the number we are looking for n.

We can then write "two-thirds of the number" as 2/3n

We can also write "one-half of a number" as 1/2n

Finally, we are told 1/2n is the same as 2/3n −8 or: 1/2n = 23n −8  

We can now solve for n: 1/2n − 2/3n = 2/3n −8 − 2/3n 1/2n − 2/3n = −8We next need to get the fractions over common denominators, in this case, 6 by multiplying each fraction by the necessary for of 1: (3/3) 1/2n − (2/2) 2/3n = −8 3/6n − 4/6n = −8 − 1/6n = −8.  

We can finally solve for n by multiplying by -6 to isolate n −6 ⋅(−1/6)n = −8⋅ − 6  

1n = 48

n =48

Answer:

6,2

Step-by-step explanation:

The fourth point of the parallelogram will be (-6,1) so option (C) will be correct.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

The slope of the green lines and red line should be same for being it a parallelogram.

Slope of green line = (7-2)/(3-1) = 2.5

So the only coordinate is matching the slope 2.5 of red line is (-6,1).

Slope = (6-1)/(-4+6) = 2.5

Hence "The fourth point of the parallelogram will be (-6,1)".

Answer:

I believe the answer is x=7

Step-by-step explanation:

Answer:

x +3 = y

Step-by-step explanation:

So you are looking for mx + b = y

m is the slope

b is the initial value

Try to isolate the y variable

x - y = -3

Subtract x from both sides

-y = -x - 3

Multiply everything by -1 to make the y value positive

y = x + 3

Answer:

x=√2 or x=−√2

x=±√2

Step-by-step explanation:

12x^2=24

Step 1: Divide both sides by 12!

12x^2/12=24/12

x^2=2

Step 2: Take the square root!

x=±√2

The solution of the equation 12x² = 24 is x = ±√2.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, the equation is :

12x² = 24

now, to solve for x :

divide both side by 12 :

x² = 24/12

x² = 2

take square root both  side :

x = ±√2

Therefore, the solution of the equation 12x² = 24 is x = ±√2.

Answer:

The radius of the circle is 4 meters.

Thus, 2nd option is correct.

Step-by-step explanation:

Given

Area of a circle = 16π squared meters.

To determine

The radius of the circle = r = ?

Using the formula

Area of circle = πr²

substitute Area of circle = 16π and in the equation

16π = πr²

switch the sides

πr² = 16π

divide both sides by π

πr²/π = 16π / π

r² = 16

r = 4, r = -4

As radiud can not be negative, so

r = 4 meters

Therefore, the radius of the circle is 4 meters.

Thus, 2nd option is correct.

Given:

[tex]\dfrac{9}{10}[/tex] divided by 3.8.

To find:

The quotient.

Solution:

We have,

[tex]\dfrac{9}{10}[/tex] divided by 3.8.

Mathematically it can be written as

[tex]\dfrac{9}{10}\div 3.8[/tex]

Convert the decimal into fraction by multiplying and dividing by 10.

[tex]=\dfrac{9}{10}\div \dfrac{38}{10}[/tex]

[tex]=\dfrac{9}{10}\times \dfrac{10}{38}[/tex]       [Reciprocal rule of division]

[tex]=\dfrac{9}{38}[/tex]                     (Cancel out the common factors)

[tex]\approx 0.237[/tex]

Therefore, the quotient is [tex]\dfrac{9}{38}[/tex], which is approximately 0.237.
