Find X Give your answer in simplest form

Answers

Given:

A figure of a right angle triangle.

To find:

The value of x.

Solution:

In a right angle triangle,

[tex]\tan \theta = \dfrac{Opposite}{Adjacent}[/tex]

In the given triangle,

[tex]\tan (30^\circ) = \dfrac{x}{7}[/tex]

[tex]\dfrac{1}{\sqrt{3}}=\dfrac{x}{7}[/tex]

On multiplying both sides by 7, we get

[tex]\dfrac{7}{\sqrt{3}}=x[/tex]

Therefore, the value of x is [tex]x=\dfrac{7}{\sqrt{3}}[/tex].

Step-by-step explanation:

Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana's account can be
represented by the equation y = 25x + 125, where x is the number of weeks she has been mowing the lawn. What does the y-intercept of the graph
represent in this situation?

Answers

Hi there! x would be 6 weeks..

Explanation:

So here says that Jana earns $25 per week for mowing the lawn. But in “x” weeks, she earns $125...this means that you would have to divide 125 with 25 or 25 multiply by x to find the answer of x.

How much does 25 go to 100? Well it would be 5. So for $100 it would be 5 weeks. We also know that 25 is 1 week. So add 5 with 1. 5 plus 1 would be 6.

Therefore, for $125, Jana would have to work for 6 whole weeks.

The diagonals of a rectangle have length 12 and intersect in a 40 degree angle. Find the length and width rounded to the nearest tenth.

Answers

Answer:

Length is 7.7 and width is 9.2

Step-by-step explanation:

The length and width of the rectangle will be the y and x coordinate of the diagonal line at angle of 40 degrees

Length L = dsin theta

Width W = d coos theta

d is the length of the diagonal

Given

d  = 12

theta = 40°

Substitute

Length = 12sin40°

Length = 12(0.6428)

Length = 7.7135

Length ≈ 7.7

Width = 12cos 40

Width = 12(0.7660)

Width = 9.192

Width = 9.2

Hence the length is 7.7 and width is 9.2

Answers

Answer:

a.(10,23)

b.(7,30)

e.(20,20)

Step-by-step explanation:

We are given that

x=Width of garden

y=Length of garden

According to question

[tex]x\geq 5[/tex]

[tex]y\geq 20[/tex]

Perimeter of rectangle=[tex]2(x+y)[/tex]

Where x=Width  of rectangle

y=Length of rectangle

Fencing used =[tex]2(x+y)[/tex]

[tex]2(x+y)\leq 80[/tex]

First we change inequality  into equality

[tex]x=5[/tex]...(1)

[tex]y=20[/tex]...(2)

[tex]2(x+y)=80[/tex]

[tex]x+y=40[/tex]...(3)

Substitute x=0 in equation (3)

[tex]y=40[/tex]

Substitute y=0  in equation (3)

[tex]x=40[/tex]

Substitute x=0 and y=0 in equation (3)

[tex]2(x+y)\leq 80[/tex]

[tex]0\leq 80[/tex]

It is true. Therefore, the  shaded region below the line.

[tex]0\geq 5[/tex]

[tex]0\geq 20[/tex]

These are false equation .Therefore, the shaded region above the line.

Substitute x=5 in equation (3)

[tex]5+y=40[/tex]

[tex]y=40-5=35[/tex]

Substitute y=20 in equation (3)

[tex]x+20=40[/tex]

[tex]x=40-20=20[/tex]

Intersection point of equation (1) and (3) is (5,35) and intersect point of equation (2) and (3) is (20,20).

Now,

a.(10,23)

Substitute in

[tex]2(x+y)\leq 80[/tex]

[tex]2(10+23)\leq 80[/tex]

[tex]66\geq 80[/tex]

10>5 and 23>20

it satisfied all inequality.

Hence, it is a solution.

b.(7,30)

7>5

30>20

[tex]2(7+30)=74<80[/tex]

it satisfied all inequality.

Hence, it is a solution.

c.(18,25)

18>5

25>20

[tex]2(18+25)=86>80[/tex]

It does not satisfied third inequality

Hence, it is not a solution.

d.(8,35)

8>5

35>20

[tex]2(8+35)=86>80[/tex]

It does not satisfied third inequality

Hence, it is not a solution.

e.(20,20)

[tex]2(20+20)=80[/tex]

20>5

20=20

it satisfied all inequality.

Hence, it is a solution.

Rochelle is competing in a marathon. She knows that once she runs 14.7 km she will have completed 35% of the marathon

Answers

Given :

Rochelle is competing in a marathon.

She knows that once she runs 14.7 km she will have completed 35% of the marathon.

To Find :

Total length of the marathon.

Solution :

Let, total distance of the marathon is x km.

So, 35% of x is 14.7 .

In mathematics :

[tex]14.7 = x\times \dfrac{35}{100}\\\\x = \dfrac{14.7\times 100}{35}\\\\x = 42\ km[/tex]

Therefore, total length of the marathon is 42 km.

The measure of an exterior angle of a triangle is 40°. What is the sum of the measures of the corresponding remote interior angles?​

Answers

Answer:

40 degrees

Step-by-step explanation:

Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40.

If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40°.

What are Triangle theories?A triangle is the smallest polygon with three sides and three interior angles.Theorem 1: The Sum of Angles property of a triangle states that the sum of the interior angles of a triangle is 180°.Theorem 2: If you lengthen one side of a triangle, the resulting exterior angle is the sum of the two opposite interior angles of the triangle.A exterior angle equals the sum of his two other angles in the triangle, so the sum of the angles in the triangle is 180 degrees. In other words, the other two angles of the triangle (which together make up the exterior angle) must be combined with the third angle to make a 180 degree angle.

40 degrees is the sum of the measures of the corresponding remote interior angles.

Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40°.
