Answer:

Option C will be your answer

Step-by-step explanation:

have a nice day and good luck!! :)

Step-by-step explanation:

Equation 1

[tex]\frac{xy}{5}-\frac{1}{x}\\\\ by\ taking\ LCM \\\\ \frac{x^2y-5}{5x}[/tex]

Equation 2

[tex]\frac{ac}{5}+\frac{4}{c} \\\\ by\ taking\ LCM \\\\ \frac{ac^2+20}{5c}[/tex]

Use the second equation. Replace x with the answer choices and if it equals the y value than that is the answer:

Y = x + 6

-4.5 + 6 = 1.5

The answer would be C. (-4.5,1.5)

Answer:

c(−4.5,1.5) is your answer

Answer:

25.75x+9.25

Step-by-step explanation:

9.25 is the constant. You multiply the ticket by the amount of people to get ticket cost. Then you add ticket cost 9.25 to get final answer.

Inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We have been given that the group of friends has no more than $245  to spend on parking and admission.

And the parking is $9.25, and tickets cost $25.75 per person, including tax.

Let the number of people would be p who can go to the amusement park,

So the inequality that expresses the relationship is

⇒ 9.25 + 25.75 × p ≤ 245  

Therefore, inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.

Both

Step-by-step explanation:

They will both give you the same answer.

-13-5 = -18

-13 + -5 = -18

Answer:

Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.

Step-by-step explanation:

Step-by-step explanation:

What you are dealing with is what we call special right triangles. There are two types of right triangles.

30-60-90 triangle- A special

right triangle with side length ratio as

[tex](a)(a \sqrt{3} )(2a)[/tex]

, where a is any positve number

45-45-90- a special right triangle which side length ratios are

[tex](a)(a)(a \sqrt{2)} [/tex]

where a is any positve number.

45 45 90 triangles is indicated by two congruent side measures( if the legs are congruent and it has a right angle, it is a 45-45-90.

30-60-90 triangles is indicated by a having at least two of the following angles given (30,60, and 90).

Shortcuts:

For a 45 45 triangle,

the legs are equal while the hypotenuse is the sqr root of 2 times than the legs.

Example, look at 1. The legs side length is 12 so our hypotenuse side length will be

[tex]12 \sqrt{2} [/tex]

For a 30-60-90 triangle, the side that is adjacent to the 30 and 90 degree measure sqr root of 3 times more than the horizontal leg.

the slanted side or the side which is adjacent to the 30 and 60 degree angle is twice the length of the horizontal leg or the side that is adjacent to the 60 and 90 degree.

Example, look at 3. We need to find x but we are given the horizontal side so just multiply sqr root of 3 to 12.

[tex]x = 12 \sqrt{3} [/tex]

[tex]1.12 \sqrt{2} [/tex]

2.Both equal

[tex]2.8 \sqrt{2} [/tex]

[tex]3.12 \sqrt{3} [/tex]

4. a=13

[tex]4.13 \sqrt{3} [/tex]

[tex]5.9 \sqrt{4} [/tex]

Answer:

12

Step-by-step explanation:

think of the ratio as a fraction. 20/3 if f is 20 and t is 3 then when f is 80 t should be 12 because 20*4 is 80 and 3*4 is 12

=========================================================

Work Shown:

(# of fish)/(# of turtles) = (# of fish)/(# of turtles)

20/3 = 80/x

20x = 3*80 ........ cross multiply

20x = 240

x = 240/20 ....... divide both sides by 20

x = 12

There are 12 turtles in the pond.

Note how the ratio 80:12 reduces fully to 20:3 after dividing both parts by 4.

Answer:

34 degrees.

Step-by-step explanation:

First of all, the sum of a triangle's degree is 180.

The angle next to the 101 is 79 degree due to the rule of supplementary angle. The angle vertical to 28 is also 28. (Vertical angles are equal).

Now we now the two side, we can figure out the last side.

180-28-79= 73

The last angle is 73 degrees. However, we are looking for x.

x+39=73

All we have to do now is subtract 39 from 73, and that leaves us with 34.

Answer:

1.3

Step-by-step explanation:

Looking at the triangle, the first thing we can notice is that it is a right triangle, so we can use trigonometric ratios to solve for missing sides.

The side the problem is asking us to find is leg HI, which happens to be the hypotenuse of triangle HIJ.

We also know one side length: HJ= 1.2 ft, and one angle measure: ∠I=72°.

In these types of problems, there are two trigonometric ratios we can look to:

You can actually use either of these to solve your problem, but for convenience let's use cosecant.

Answer:

.812

Step-by-step explanation:

13/16 = .812

The fraction sign also means to divide, so all you do is 13/16 = .812

Work:

First, multiply 13 by 10^1 to get 130, then you can divide.

[tex]\sqrt[16]{130} \\[/tex]  = 8.12. Finally, you take the 10^1 you did from 130 and divide 8.12 to get .812

Answer:

the largest block represents the hypotenuse which would be c² the smallest can either be a or b and the block thats left over will be the letter you didn't use for the small block so in terms the blocks represents a²+b²=c²

[tex]\bold{a^2+b^2=c^2}[/tex] is indeed the Pythagorean theorem. It implies that adding the hypotenuse square as well as the two sides of a right triangle equals the hypotenuse square.

Answer:

1. DC = AB = 4 ft

2. BD = 10.80 ft

3. m<CED = [tex]90^{0}[/tex]

4. m<EBC = [tex]65^{o}[/tex]

Step-by-step explanation:

From the given quadrilateral,

Given: AB = 4 ft, AD = 10 ft and m<BAE = 65.

1. DC = AB = 4 ft (opposite sides of a parallelogram are equal)

2. Applying the Pythagoras theorem to ΔABD, we have;

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]BD^{2}[/tex] = [tex]4^{2}[/tex] + [tex]10^{2}[/tex]

       = 16 + 100

       = 116

BD = [tex]\sqrt{116}[/tex]

     = 10.7703

BD = 10.80 ft

3. m<CED = [tex]90^{0}[/tex] (the diagonals bisects each other at right angle)

4. m<ABC + m<BAC + m<ACB = 180

90 + 65 + m<ACB = 180

m<ACB = 180 - 155

m<ACB = [tex]25^{0}[/tex]

So that,

m<BEC + m<EBC + m<ECB = 180

90 + m<EBC + 25 = 180

m<EBC = 180 - 115

m<EBC = [tex]65^{o}[/tex]

Answer:

3,4.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]

[tex]\Delta = b^{2} - 4ac[/tex]

In this question:

The function is:

[tex]g(x) = \frac{x^2+4x-5}{x^2-7x+12}[/tex]

In a fraction, the values not in domain are the values for which the denominator is 0.

Find all values of that are NOT in the domain of g.

It will not be in domain if the denominator is 0. So

[tex]x^2 - 7x + 12 = 0[/tex]

That is, a quadratic equation with [tex]a = 1, b = -7, c = 12[/tex]

[tex]\Delta = (-7)^{2} - 4(1)(12) = 49 - 48 = 1[/tex]

[tex]x_{1} = \frac{-(-7) + \sqrt{1}}{2(1)} = 4[/tex]

[tex]x_{2} = \frac{-(7) - \sqrt{1}}{2(1)} = 3[/tex]

The values are 3 and 4, so the answer is 3,4.

Answer:

Yes

Step-by-step explanation:

In right-angled triangles, the Theorem of Pythagoras can be applied. (The hypotenuse squared is equal to the sum of the other two sides squared).

The hypotenuse is always the longest side, therefore if it's a right-angled triangle:

15²+35² should equal to 38² and in this case it does.
