Part of the roof of a factory is devoted to mechanical support and part to green space. The area G that is designated as green space can be modeled by the polynomial 2x^2 - 7x and the area M that is devoted to mechanical support can be modeled by the polynomial x^2 - 9x + 24. Given that the area R of the roof is 36 square yards, write and solve a quadratic equation to find the total area of the green space. **Use the positive value for your solution.

A cone and a cylinder have the same base and height as shown below. The volume of the cylinder is 84*3.14in. What can be concluded about the volume of the cone . Check all that apply

Answers

Answer:

28*3.14in

Step-by-step explanation:

Let's consider the formula of these shape first.

For the cylinder

Volume = πr²h

While for the cone

Volume = 1/3πr²h

Just mere looking at the formula we know that if the volume of the cylinder is given, that of the cone will be 1/3 of it.

From the question .

The two have same base and height, indicating equal radius also.

If the volume of the cylinder is 84*3.14in then that of the cone will he 1/3 of 84*3.14in = 28*3.14in

Answers

Answer: I’m confident with Kai being the correct answer

Kai labeled the triangles such that ΔABC is similar to ΔXYZ.

What is a triangle?

A triangle is a two-dimensional geometrical figure that has three sides, three vertices, and three interior angles.

As per Tatyanna:

In ΔABC, ∠B = 54.3°, ∠C = 61.2°

Therefore, ∠A = 180° - (54.3° + 61.2°) = 64.5°

In ΔXYZ, ∠Z = 64.5°, ∠Y = 54.3°

Therefore, ∠X = 180° - (64.5° + 54.3°) = 61.2°

As per Simon:

In ΔABC, ∠A = 63.2°, ∠B = 58.4°

Therefore, ∠C = 180° - (63.2° + 58.4°) = 58.4°

In ΔXYZ, ∠Z = 63.2°, ∠Y = 58.4°

Therefore, ∠X = 180° - (63.2° + 58.4°) = 58.4°

As per Anders:

In ΔABC, ∠A = 59.8°, ∠B = 60.6°

Therefore, ∠C = 180° - (59.8° + 60.6°) = 59.6°

In ΔXYZ, ∠X = 59.8°, ∠Z = 60.6°

Therefore, ∠Y = 180° - (59.8° + 60.6°) = 59.6°

As per Kai:

In ΔABC, ∠B = 60.9°, ∠C = 57.7°

Therefore, ∠A = 180° - (60.9° + 57.7°) = 61.4°

In ΔXYZ, ∠X = 61.4°, ∠Z = 57.7°

Therefore, ∠Y = 180° - (61.4° + 57.7°) = 60.9°

Therefore, the sequence and the value of the angles for ΔABC and ΔXYZ matches only with Kai's drawings.

Therefore, as per his drawings, ΔABC and ΔXYZ will look similar.

What is the equation of a line with a slope of 6 and y intercept of -2

Answers

Answer:

6x-y=2 is the equation

Step-by-step explanation:

The formula is y= mx+c where m= slope and c = y-intercept

so replacing their values,

y = 6x -2

y+2= 6x

6x-y = 2 is the required equation.

Answer:

y=6x-2

Step-by-step explanation:

Answer: to write an equation it has to be y=mx+b

The slope is 6, so you substitute the 6 in for the m. M is always the slope.

You also keep the x there.

The y intercept, also know as b, is -2 so you substitute that in for b.

Then you get the equation on the line.

y=6x-2!

The length of a rectangular plot is expressed as x²m and the breadth is xm if the area of the rectangular plot is 5832sqcm then find it's length and breadth

Answers

Answer:

Length = x^2 = 0.835^2 = 0.698 m = 69.8cm

Breadth = x = 0.835 m = 83.5cm

Step-by-step explanation:

Given;

Length of the rectangular plot l = x^2 m

Breadth b = x m

Area A = 5832 cm^2 = 0.5832 m^2

(They should be converted to the same units before solving: length in metres and area in square metres)

The area of a rectangular plot can be calculated using the formula;

Area = length × breadth

A = l × b

Substituting the values of l and b;

A = x^2 × x

A = x^3

Substituting the value of A;

0.5832 = x^3

solving for x;

x = (0.5832)^(1/3)

x = 0.835 m

Length = x^2 = 0.835^2 = 0.698 m = 69.8cm

Breadth = x = 0.835 m = 83.5cm

Simplify 8^2/3 -√9×10^0+(1/144)^-1/2

Answers

Answer:

13

Step-by-step explanation:

We have the following expression:

[tex]8^{\frac{2}{3} } -\sqrt{9}*10^{0} + (\frac{1}{144}) ^{-\frac{1}{2} }[/tex]

If we do part by part, we have remains:

[tex]8^{\frac{2}{3} }[/tex] = 4

8 = 2^3

Therefore, the exponents 3 * 2/3 = 2 are multiplied

2^2 = 4

[tex]\sqrt{9}*10^{0}[/tex] = 3

We know that the root of 9 is equal to 3 and that every number raised to 0 is equal to 1, therefore 1 * 3 = 3

[tex](\frac{1}{144}) ^{-\frac{1}{2} }[/tex] = 12

When the exponent is negative, the fraction can be inverted and at the end there is 144 ^ 1/2, which would be the root of 144, which is equal to 12.

So, we have:

A total of 354 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?

Answers

There are 118 adult tickets sold

This is because 354/3 =118

and 118+118=236

236 are the child tickets

therefore 118 are the adult tickets.

Hope this helped!

The total number of adult ticket sold is 118 tickets.

Application of linear equation.

Let's write "x" to represent how many adult tickets were sold.

The information provided indicates that there were twice as many student tickets sold as adult tickets. The quantity of student tickets sold can therefore be stated as 2x.

There were 354 total tickets sold, which includes both student and adult tickets.

We may construct an equation based on the total number of tickets to resolve this issue:

x + 2x = 354

Combining comparable variables

3x = 354

x = 354 / 3

x = 118

118 adult tickets were consequently sold.

Archaeology students are constructing a replica of the Great Pyramid of Giza that they will then fill with sand. The replica is to be 120the size of the original pyramid. The Great Pyramid is approximately 147 meters tall and each side of the base is approximately 230 meters long. Based on these measurements, how many cubic meters of sand will the students need? Round your answer to the nearest whole number.

Answer: 972 m^3 of sand

Step-by-step explanation:

Height of original pyramid = 147 meters

Each side of the base = 230 meters (that is both the base length and base width).

If replica pyramid is to be 1/20 the size of the original pyramid :

Size dimension of replica pyramid will therefore be,

Height = 1/20 × 147 = 7.35metres

Each Base = 1/20 × 230 = 11.5 metres

To calculate the amount of sand required, we can get these by Calculating the volume of the pyramid which us the amount of space occupied by an object.

The volume of a pyramid is given by:

(Base length × base width × height) ÷ 3

( 7.35 m × 11.5 m × 11.5 m) / 3

972.0375 m^3

That means the volume of the pyramid is 972.0375 m^3
