Answer:

A

Step-by-step explanation:

using the sine ratio and the exact values

sin30° = [tex]\frac{1}{2}[/tex] and sin60° = [tex]\frac{\sqrt{3} }{2}[/tex]

calculate the height of the wall below x , call it h

the hypotenuse is the length of the ladder

using the sine ratio in the lower right triangle.

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{18}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2h = 18 ( divide both sides by 2 )

h = 9

lower part of the wall is 9 meters

using the sine ratio in the right triangle on the right

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{9+x}{18}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2(9 + x) = 18[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

9 + x = 9[tex]\sqrt{3}[/tex] ( subtract 9 from both sides )

x = 9[tex]\sqrt{3}[/tex] - 9 = 9([tex]\sqrt{3}[/tex] - 1)

Answer:

[tex]\textsf{A)} \quad x=9(\sqrt{3}-1)[/tex]

Step-by-step explanation:

Interior angles of a triangle sum to 180°.  Therefore, if the ladder makes an angle of 30° with the ground, the angle it makes with the wall is 60°.

Therefore, the two triangles are congruent as their corresponding angles are the same and the length of their longest side (hypotenuse) is the same.

30-60-90 Triangle Theorem

A 30-60-90 triangle is a special right triangle where the measures of its angles are in the ratio 1 : 2 : 3 and the measure of its sides are in the ratio 1 : √3 : 2.

The formula for the sides is  b : b√3 : 2b  where:

Therefore, as the length of the hypotenuse is 18:

[tex]\implies 2b=18[/tex]

[tex]\implies b=9[/tex]

[tex]\implies b\sqrt{3}=9\sqrt{3}[/tex]

To find x, subtract the length of the shortest leg of the right triangle from the length of the other leg of the right triangle:

[tex]\implies x=9\sqrt{3}-9[/tex]

[tex]\implies x=9(\sqrt{3}-1)[/tex]

The least number of visits he needs to make in order to earn a free movie ticket is approximately 15 visits.

Points received for signing up = 85 rewards points

Points received for each visit to the movie theater = 10.5 points

Points needed for a free movie ticket = 240 points

Number of visits = x

85 + 10.5x ≤ 240

10.5x ≤ 240 - 85

10.5x ≤ 155

x ≤ 155 / 10.5

x ≤ 14.761

Approximately,

x ≤ 15 visits

Therefore, Jordan needs at least 15 visits to earn a free movie ticket.

Answer:

x = 147

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 7 , then

sum = 180° × 5 = 900°

sum the interior angles and equate to 900

x + 141 + 112 + 129 + 106 + 139 + 126 = 900

x + 753 = 900 ( subtract 753 from both sides )

x = 147

The surface area and the volume of solid prism are 432in² and 576in³ respectively.

A rectangular prism is simply a three-dimensional solid shape which has six faces that are rectangles

The surface area of a rectangular prism is expressed as;

A = 2( wl + hl + hw )

The volume of a rectangular prism is expressed as;

V = w × h × l

Where w is the width, h is height and l is length.

Given the data in the question;

The surface area of the solid is;

A = 2( wl + hl + hw )

A = 2( (8in × 12in) + (6in × 12in) + (6in × 8in) )

A = 2( 96in² + 72in² + 48in² )

A = 2( 216in² )

A = 432in²

Therefore, surface area of the rectangular prism is 432in²

The volume of the solid is;

V = w × h × l

V = 8in × 6in × 12in

V = 576in³

Therefore, volume of the rectangular prism is 576in³

The amount of money that Ahmed gave to his brother is AED 140.

It is given in the question that Ahmed has AED 180. He gives his brother 0.7  with bar notation of the amount he has.

We have to find the amount given by Ahmed to his brother.

Here, we have to convert a non-terminating but recurring rational number into fraction form.

Let 0.7 bar = x

Multiplying the equation by 10, we get

7.7 bar  = 10x

10x - x = 7.7 bar - 0.7 bar

9x = 7

x = 7/9

Hence, Ahmed gave 7/9 of the amount he had to his brother.

Hence, we can write,

Amount given to Ahmed's brother by Ahmed = (7/9)*180 = AED 140.

The measure of m∠ABD in the figure shown is 19°.

Given:

∠BCD = 71°

In the figure, ΔABC is an isosceles triangle where AB = BC.

According to the Isosceles Triangle Theorem, an isosceles triangle has equal angles on either side of its equal sides.

So, ∠BAD = ∠BCD = 71°

The sum of angles in a triangle sums to 180°.

∠ABC + ∠BAD + ∠BCD = 180°

∠ABC + 71° + 71° = 180°

∠ABC + 142° = 180°

∠ABC = 180° - 142° = 38°

DB is the angle bisector of ∠ABC.

Now, ∠ABD = ∠CBD = 38°/2 = 19°

The measure of ∠ABD is 19°.

There will  be no interval of time when Josue has more in savings than Arianna, they have same savings is after 4 weeks

Step one:

For Josue

initial savings balance= $70

weekly savings = $9

Let J represent amount of money Josue has saved and  t the number of weeks after the beginning of the year

The total amount in the savings after t weeks is

J=9t+70-------1

For Arianna

initial savings balance= $30

weekly savings = $19

Let A represent the amount of money Arianna has saved and  t the number of weeks after the beginning of the year

The total amount in the savings after t weeks is

J=19t+30---------2

Step two

equation 1 and 2 to find t

9t+70=19t+30

9t-19t=30-70

-10t=-40

divide both sides by 10

t=4

t=4 weeks

so after 4 weeks Josue and Arianna will have the same amount of money

For Josue t=4

J=9(4)+70-------1

J=36+70

J=$106

For Arianna t=4

A=19(4)+30---------2

A=76+30

Answer:

1) 54+2x=5x−6−18x Distributive Property

2) 60=−15x Division Property of Equality

3) −4=x Division Property of Equality

Explanation:

1.) This answer is Distributive Property because the parenthesis in the original equation were removed through the process of distributing.

3(–2 – 6x) was distributed by multiplying 3 • –2 and 3 • –6x to get –6 – 18x

2.) This answer is Division Property of Equality because for all real numbers x, y, and z, if x = y and z ≠ 0, then x/z = y/z. This is true in this equation because of 60/–15 = −15x/–15.

3.) Division is used to get the value of x, which is –4.

Answer:

what is the symbol between the 2 fractions?

The possible values of the number will be -62/4 or -31/2.

Multiplication of numbers may be defined as the tool or arithmetic operation which can be used to increase the count of a number. For example, if there is a number 4, then in order to increase the number it will be multiplied with some other number like 9. Now, the number will be 4×9 = 36. We are given that the product of -4 with a number gives the answer as 62. Let us assume the number as x and form the equation in accordance with the data given in the question.

-4×(x) = 62

Now, to find x we divide -4 on both the sides and we get

x = -62/4

This number can also be simplified by dividing both numerator and denominator with 2 and we get

x = -31/2.

To solve for x, you must isolate the variable.

First, start by adding 2 to BOTH sides to eliminate the 2.

3÷1/3 = x

3/1 × 3/1 = x

9 = x

The value of n is 1/2 and it is not an even number or odd number

From the question, the steps are given as

n + n + 1 = 2n + 1

n + n + 1 = 2n+2-1

n + n + 1 = 2(n+1) -1

Also, from the question, we have the result of the expression to be

2

This means that

n + n + 1 = 2

Substitute n + n + 1 = 2(n+1) -1 in the equation n + n + 1 = 2

So, we have

2(n + 1) - 1 = 2

Add 1 to all sides of the equation

So, we have

2(n + 1) = 3

Divide both sides of the equation by 2

So, we have

n + 1 = 3/2

Subtract 1 from all sides

n = 1/2

The above implies that the number n is neither an even number, nor an odd number

This is so because the result is a fraction
