Answer:

The answer is 9 on edgggggggggggg

Step-by-step explanation:

Based on the information given, the value of h is 9.

Firstly, it should be noted that the sum of the angles that are on a straight line is 180°.

In this case, we'll have to equate both values that are given and this will be:

3h + 18° + 15h = 180°

Collect like terms

3h + 15h = 180° - 18°

18h = 162°

Divide both sides by 18

18h/18 = 162°/18

h = 9

Therefore, the value of h will be 9

Answer:

Step-by-step explanation:

The given question says that, the man is standing 50 ft away from the statue.

Looking at the top of the statue, the  angle of elevation is 8°.

Hence, where the man is standing, from that horizontal plane, the distance of the top of the statue is [tex]50 tan 8°[/tex].

Similarly, looking down towards the base, the angle is 14°.

Hence, the height from the base of the statue to the horizontal plane, where the man is standing is [tex]50 tan 14°[/tex].

The total height of the statue is [tex]50 tan 8° + 50 tan 14° = 50( tan 8° + tan 14°)[/tex] = 22.24475804 ≅22.24 ft.

Answer: [tex]27a^6[/tex]

Step-by-step explanation:

The question is not clear. So, assuming that the expression you need to simplify is this one:

[tex](3a^2)^3[/tex]

You need to remember a property called "Power of a power property". This property states the following:

[tex](b^m)^n=b^{(m*n)}=b^{(mn)}[/tex]

Therefore, you need to apply the Power of a power property explained before, in order to simplify the expression provided in the exercise, multiplying the exponents inside the parentheses by the exponent outside of the parentheses. Then:

[tex](3a^2)^3=3^{(1*3)}a^{(2*3)}=3^3a^6[/tex]

Now, you must remember that:

[tex]3^3=3*3*3=27[/tex]

Finally, you get:

[tex]=27 a^6[/tex]

Answer:

V=(4/3)πr^3

Step-by-step explanation:

This is the equation to find the volume of a sphere

V=(4/3)πr^3

than plug in 6 for x, and solve

The volume of a sphere with a radius of 6 units is represented by the expression [tex]\frac{4}{3}[/tex] πr³, which calculates to V = [tex]\frac{4}{3}[/tex] π(6)³, cubic units. If two such spheres combine, the volume doubles, and the new radius is the cube root of the new volume.

The expression that represents the volume of a sphere with a given radius in cubic units is given by the formula V = [tex]\frac{4}{3}[/tex] πr³. For a sphere with a radius of 6 units, you can substitute the value of the radius into this formula to calculate the volume.

The calculated volume V would be V = [tex]\frac{4}{3}[/tex] π(6)³, which simplifies to V = [tex]\frac{4}{3}[/tex] π(216), or V = 288π cubic units. Therefore, the volume of the sphere is 288 times π cubic units.

Answer: [tex]=24+(1+92)[/tex]

Step-by-step explanation:

For this exercise you need to remember a property called "Associative Property".

The Associative Property states that it does not matter how you group the numbers, because you will always obtained the same result.

For Additiion, the Associentive property states the following:

[tex]a + (b + c) = (a + b) + c[/tex]

Where "a", "b" and "c" are Real numbers.

In this case you have:

[tex](24+1)+92[/tex]

As you can notice, the number 24 and the number 1 are grouped inside the parentheses, but you can also regroup the numbers 1 and 92 using parentheses and you will have the same result.

Therefore, based on the Associative Property explained before, you can conclude that:

[tex](24+1)+92=24+(1+92)[/tex]

The thickness of a stack of 8 sheets of metal, each 2/3 of an inch thick, is 5 1/3 inches.

To determine the thickness of a stack of 8 sheets of metal that are each 2/3 of an inch thick, we simply multiply the thickness of one sheet by the number of sheets in the stack:

(2/3 inch/sheet) x 8 sheets = (2/3) x 8

Now, we simplify the expression by multiplying 2 by 8 which equals 16, and then we keep the same denominator:

16/3 inches

This fraction can also be converted to a mixed number:

5 1/3 inches

So, the stack will be 5 1/3 inches thick.

Answer:

The homeowner can buy 144 tiles maximum.

Side length = 16 feet.

Step-by-step explanation:

The cost of each tile is $3.45.

So, at $500, the homeowner can buy [tex]\frac{500}{3.45} = 144.92[/tex] ≈ 144 number of tiles. {As the number of tiles can not be a fraction.}

Since each tile is a square with area 256 square inches, so the homeowner can arrange the tiles in 12 by 12 arrangements.

Each tile has side length = √256 = 16 inches.

So, the side length of the largest patio is (16 × 12) inches = 16 feet. (Since, 1 foot = 12 inches). (Answer)

Equation: [tex]8.5t+6.5=57.5[/tex]

Solution: [tex]t=6[/tex]

Step-by-step explanation:

Let be "t" the number of movie tickets bought by the group of friends.

According to the information given in the exercise, the price of each movie ticket is: $8.50.

Then, you can represent the amount (in dollars) the group of friends spent in movie tickets, with this expression:

[tex]8.5t[/tex]

You know that one person spent $6.50, then the expression that represents the total amount (in dollars) the group of friends spent in food and movie tickets, is:

[tex]8.5t+6.5[/tex]

Since that total amount spent is given in the exercise, you can write the following equation to determine how many tickets were bought:

[tex]8.5t+6.5=57.5[/tex]

Finally, you can solve for "t" in order to find the solution of the equation. This is:

[tex]8.5t=57.5-6.5\\\\t=\frac{51}{8.5}\\\\t=6[/tex]

Final answer:

The group purchased 6 movie tickets. The equation formulated to determine this is t × $8.50 + $6.50 = $57.50, where t stands for the number of tickets. Subtracting the food cost and dividing the remainder by the ticket cost gives us the answer.

Explanation:

To determine how many movie tickets were bought by the group, we can set up the following equation:

t × $8.50 + $6.50 = $57.50

Here, t represents the number of tickets. The cost of one movie ticket is $8.50 and the cost of the food is $6.50. The total amount spent by the group is $57.50.

To solve for t, subtract the cost of the food from the total amount:

$57.50 - $6.50 = $51

Now divide the remaining amount by the cost of one ticket to find the number of tickets:

$51 ÷ $8.50 = 6

Therefore, the group purchased 6 movie tickets.

Answer:

TV is 3 inches tall.

Step-by-step explanation:

Given: Diagonal length of TV is 5 inch

            Width of TV is 4 inches.

Considering TV to be in rectangle shape.

Lets assume the TV height to be "x"

Diagonal form a right angle triangle as shown on picture attached.

∴ using pathagorean theoram to find the height of TV.

[tex]h^{2} = a^{2} + b^{2}[/tex], where h is hypotenous, a is width or adjacent and b is height or opposite side.

∴ [tex]5^{2} = 4^{2} + x^{2}[/tex]

⇒[tex]25= 16+x^{2}[/tex]

subtracting both side by 16

⇒[tex]25-16= x^{2}[/tex]

⇒[tex]x^{2} = 9[/tex]

Taking sqaure root on both side.

Remember, √a²= a

⇒[tex]x= \sqrt{9}[/tex]

∴[tex]x= 3[/tex]

Hence, the height of TV is 3 inches.

The diameter of hemisphere is 61.4 units

Solution:

Given that, volume of hemisphere is 60570 cubic units

To find: Diameter of hemisphere

The formula for volume of hemisphere is given as:

[tex]V = \frac{2}{3} \pi r^3[/tex]

Where, "r" is the radius of hemisphere

Substituting the values we get,

[tex]60570 = \frac{2}{3} \times 3.14 \times r^3\\\\60570 = 2.093 \times r^3\\\\r^3 = \frac{60570}{2.093}\\\\r^3 = 28939.32\\\\\text{Take cube root on both sides }\\\\r = \sqrt[3]{28939.32} \\\\r = 30.7017248 \approx 30.7[/tex]

We know diameter is twice of radius

[tex]Diameter = 2 \times radius\\\\Diameter = 2 \times 30.7\\\\Diameter = 61.4[/tex]

Thus diameter of hemisphere is 61.4 units

The diameter of the hemisphere is [tex]\( 60.2 \, \text{cm} \)[/tex].

To find the diameter of a hemisphere with a volume of [tex]\( 60,570 \, \text{cm}^3 \)[/tex], we can follow these steps:

Step 1: Write a hemisphere's volume formula.

A hemisphere's volume (V) is determined by:

[tex]\[ V = \frac{2}{3} \pi r^3 \][/tex]

where ( r ) is the radius.

Step 2: Set up the equation with the given volume

Given [tex]\( V = 60,570 \, \text{cm}^3 \)[/tex], we substitute into the formula:

[tex]\[ 60,570 = \frac{2}{3} \pi r^3 \][/tex]

Step 3: Find the value of [tex]\( r^3 \)[/tex]

First, isolate [tex]\( r^3 \)[/tex]:

[tex]\[ r^3 = \frac{60,570 \times 3}{2 \pi} \][/tex]

Step 4: Calculate the value inside the equation

[tex]\[ r^3 = \frac{181,710}{2 \pi} \approx \frac{181,710}{6.2832} \approx 28,931.89 \][/tex]

Step 5: Solve for ( r )

Take the cube root of both sides to find ( r ):

[tex]\[ r = \sqrt[3]{28,931.89} \approx 30.1 \][/tex]

Step 6: Calculate the diameter

Two times the radius is the diameter (D):

[tex]\[ D = 2r \approx 2 \times 30.1 = 60.2 \][/tex]

Thus, the diameter of the hemisphere is [tex]\( 60.2 \, \text{cm} \)[/tex].

Answer: daughter = 6 years

mother = 30 years

Step-by-step explanation:

Let the daughter's age be x and the mother's age be y , then from the first statement

y = 5x  .......................... equation 1

In 6 years time , the mother will be y + 6 and the daughter will be x + 6 ,from the second statement , we have

y + 6 = 3 ( x + 6 )

y + 6 = 3x + 18 ..................................... equation 2

substituting equation 1 into equation 2 , we have

5x + 6 = 3x + 18

5x - 3x = 18 - 6

2x = 12

x = 6

Therefore , the daughter's age is 6 years ,then the mother's age will be 6x5 = 30 years

x will represent the number of tickets.

y will represent the fixed fee given by the ticket agency

6x + y = 135

3x + y = 75

To solve, we can use the process of elimination by multiplying the second equation by -2 so that 6y will cancel:

-6x - 2y = -150

+6y + y = 135

Now we simplify by adding/subtracting:

-y = -15 or y = 15

Plug the value of y into any of the two equations and solve for x. I will use the second equation:

3x + 15 = 75

3x = 60

x = 20

To set this up in slope intercept form (y = mx + b), we need to identify what m and b are.

m is x because it is not a fixed number, and b is y because it is a fixed number (price of “fixed” fee). This brings us to y = 20x + 15

Answer:

The answer is the first choice: 10x - 12 + x + 10x - 12 + x

Step-by-step explanation:

Let the length of a table 2.5x - 3 and let the width of the table be x.

Four tables with identical dimensions are placed together.

So we can say that width of the new table formed by placing the four tables side to side will be the same as the width of one table, that is x.

And the two sides of the new table which will represent the width will be the width of one table at one end and the width of the table at the other end, that is x + x.length

Now as we saw before there are are two widths which are part of the perimeter there are also two lengths which are part of the perimeter.

The perimeter of a table is given by (2 × length) + (2 × width).

Now one length of the new table will be equal to (4 × length of one table) = 4 × (2.5 x - 3) = 10x -12

Therefore perimeter of the new table is given from the formula of the perimeter = Length + width + Length + width

     =   10x - 12  + x  +  10x -12 + x

Answer:

y = x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x - 1 ← is in slope- intercept form

with slope m = - 1

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-1}[/tex] = 1, thus

y = x + c ← is the partial equation of the perpendicular line

To find c substitute (- 1, - 2) into the partial equation

- 2 = - 1 + c ⇒ c = - 2 + 1 = - 1

y = x - 1 ← equation of perpendicular line
