Answer:

Volume = 9900 ft2

Step-by-step explanation:

To find the volume of the pool, we can use the base as the trapezoid, and then we need to calculate the base area and multiply by the height.

The trapezoid has a bigger base of 8 and a smaller base of 3, with a height of 60, so the area is:

Area = (8+3)*60/2 = 330 ft2

Now, to find the volume, we just need to multiply the base area by the height of 30 feet:

Volume = Area * Height = 330 * 30 = 9900 ft2

Step-by-step explanation:

How many minutes did Betty practice?:

36 x 7=252

How many minutes in all did Jake and Betty practice?:

252+36=288

Equation:

1:7

The equations can be modeled as:

Betty = 252 minutes

Jake + Betty = 288 minutes.

Two or more expressions with an equal sign are defined as an equation.

Given that, Jake practiced piano for 36 minutes and Betty practiced for 7 times as long as Jake.

Therefore, Betty practiced for:

36 × 7 minutes

= 252 minutes.

The total time of practice is:

252 + 36

= 288 minutes.

The equations can be modeled as:

Betty = 252 minutes

Jake + Betty = 288 minutes.

Step-by-step explanation:

The line from the vertex to the base is a perpendicular bisector, that is

Using the tangent ratio on the left, right triangle, then

tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{5}{\frac{1}{2}x }[/tex] = [tex]\frac{10}{x}[/tex] ( multiply both sides by x )

Answer: 56m ; 12m

Step-by-step explanation:

A football coach walks 12 meters westward, 16 meters eastward, 22 meters westward, and then 6 meters eastward. The total distance moved will be: 12m + 16m + 22m + 6m = 56 metres.

The displacement will be:

12i + 16i - 22i + 6i

= 34i - 22i

= 12m west

Answer:

Step-by-step explanation:

Distance is scalar quantity and as such it has only magnitude and no direction.

The distance moved by the coach is calculated as;

distance = 12 meters  + 16 meters + 22 meters  + 6 meters

distance = 56 meters

Again, we determine the magnitude and direction of the displacement.

Displacement is a vector quantity and as such it has both magnitude and direction.

let westward represent positive direction, and

eastward represent negative direction

Displacement =  12 meters westward - 16 meters eastward + 22 meters westward - 6 meters eastward

Displacement = 12 meters eastward

Answer:

Yes, it can. Triangles [in order for them to be one] must equal 180. If you add all of these angles together, since a triangle only has three angles anyway, it equals to 180, so you know it's a triangle.

Answer:

Z = 1.88

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

94% confidence level

So [tex]\alpha = 0.06[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.06}{2} = 0.97[/tex], so [tex]Z = 1.88[/tex].

The critical z-value elena should use to construct the given confidence interval is; 1.88

We are given;

Formula for confidence intervals of proportion is;

CI = p^ ± z√(p^(1 - p^)/n)

Since we are given Confidence level of 94%, the significance level is;

α = 100% - 94%

α = 0.06

The the z-score will be at the p-value of 1 - α/2

P-value = 1 - (0.06/2) = 0.97

From online p-value from z-score calculator, we have; z-score = 1.88

Answer:

[tex]14+x\leq ≤ 26\\Collect like terms\\x \leq 26-14\\x \leq 12[/tex]

Step-by-step explanation:

The solution to the inequality 14 + x ≤ 26 is x ≤ 12.

To solve the inequality 14 + x ≤ 26, you can follow these steps:

1. Begin by isolating the variable "x" on one side of the inequality.

In this case, subtract 14 from both sides:

14 + x - 14 ≤ 26 - 14

x ≤ 12

2. The solution to the inequality is x ≤ 12.

This means that any value of "x" that is less than or equal to 12 will satisfy the inequality.

Therefore, the solution to the inequality 14 + x ≤ 26 is x ≤ 12.

Answer:

52.1m

Step-by-step explanation:

Please see attachment for explanatory diagram.

From the diagram:

Opposite = H

Adjacent = 20m

Angle θ = 69°

The height, H of the building can be obtained as follow:

Tan θ = Opp /Adj

Tan 69 = H/20

Cross multiply

H = 20 x Tan 69

H = 52.1m

Therefore, the height of the building is 52.1m

Answer:

283.5 cm squared

Step-by-step explanation:

The surface area of a solid is basically just the sum of the areas of all the exterior sides. In this figure, we have 3 congruent triangles at the top, 3 congruent rectangles on the sides, and 1 triangle at the base. We need to find all these areas.

3 congruent triangles:

The area of a triangle is denoted by: A = (1/2) * b * h, where b is the base and h is the height.

Here, the base of one triangle is 10 and the height is 4. So:

A = (1/2) * b * h

A = (1/2) * 10 * 4 = 20

Since there are 3 such triangles, multiply 20 by 3:

20 * 3 = 60 cm squared

3 congruent rectangles:

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

Here, the length is 6 and the width is 10, so:

A = lw

A = 6 * 10 = 60

There are 3 such rectangles, so multiply 60 by 3:

60 * 3 = 180 cm squared

1 base triangle:

Again we use the formula A = (1/2) * b * h for this area.

Here, the base is 10 and the height is 8.7, so:

A = (1/2) * b * h

A = (1/2) * 10 * 8.7 = 43.5 cm squared

Add all these together:

60 + 180 + 43.5 = 283.5 cm squared

The answer is thus 283.5 cm squared.

Answer:

283.5 cm²

Step-by-step explanation:

3 rectangles + 3 triangles on top + triangular base

3(10×6) + 3(½×10×4) + (½×10×8.7)

180 + 60 × 43.5

283.5 cm²

Answer:

[tex][(-5)-\frac{9}{(-3)^3}](-6)+(-6)=22[/tex]

Step-by-step explanation:

[tex][\left(-5\right)-\frac{9}{\left(-3\right)^3}]\left(-6\right)+\left(-6\right)[/tex]

Remove parenthesis: [tex](-a)=-a[/tex]

[tex]=-[-5-\frac{9}{\left(-3\right)^3}] * 6-6[/tex]

[tex][-5-\frac{9}{\left(-3\right)^3}]*6 = -28[/tex]

[tex]= - (-28) - 6[/tex]

Apply rule: [tex]- (-a) = a[/tex]

[tex]= 28 - 6[/tex]

Subtract the numbers: [tex]28 - 6 = 22[/tex]

Final answer:

[tex]= 22[/tex]

Answer:

m = rise / run = 10/18 = 5/9

Step-by-step explanation:

As we move from the point (0, 5) to the point  (18, -5), x increases by 18 and y decreases by 10.  Thus, the slope, m, is m = rise / run = 10/18 = 5/9.

We could get the same result using the points (0, 5) and (18, -5).

Answer:

The correct answer is - A. cultural.

Step-by-step explanation:

The exchange of music, thus creating an artistic and entertainment connection between the people of different countries, regions, or continents is a nice example of cultural connection.

The music is part of the culture of the people, and all the people from every part of the world have their own specific type of music that complements their culture.

With the globalization process, people have been able to see and hear things from all around the world, thus managing to hear the music of all pats of the world. The Japanese and Korean music have experienced a real ''boom'' in popularity in the western world, as lot of people find it interesting, and the American music also reached new countries where it became the most popular, like in Europe for example.

MARK ME BRAINLIEST PLEASE!!! :) HOPE IT HELPS

Answer:

A

Step-by-step explanation for why it's A:

The earth has become increasingly interconnected over recent times which has resulted in increased connection as well as cultural exchange amongst individuals.

This has allowed people to have access to new cultures,beliefs and ideas that were otherwise unavailable in their place of inhabitance.

Hence, Japanese music has become a lot more prevalent in the western world than it was say 60 years ago in a similar way American music has become more prevalent in Europe.

Software such as the internet have rapidly sped up globalisation and have resulted in remote accesibility to platforms such as social media that have made this cultural exchange boom in recent times possible.

Why it isn't the other options:

It could not be (b) as no forms of trading of commodities or other financial instruments are exchanged during the sharing of musical culture.

It could not be (c) as the spread of foreign culture within an area does not affect the manufacturing of goods and how they are sold between the involved countries.

It could not be (d) as certain procedures relating to the governance of a country( for instance in America)as well as political ideologies did not flourish( in a country say Japan) due to foreign musical acquisition.
