The Louvre pyramid in Paris is built of glass panes. The top row has 4 glass panes, and each row after it has 4 more panes than the previous row. How many panes of glass are in the 16th row?

Answers

Answer:

Number of glass panel in 16th row = 64

Step-by-step explanation:

Given:

Number of glass panel in first row = 4

Each next row added number of glass panel = 4

Find:

Number of glass panel in 16th row

Computation:

An = a + [n-1]d

An = given term = A16

a = first term = 4

n = number of term = 15

d = Common difference = 4

An = a + [n-1]d

An = 4 + [16-1]4

An = 4 + [15]4

An = 4 + 60

An = 64

Number of glass panel in 16th row = 64

$180 divided by 0.20 is $900

A percentage is a way to describe a part of a whole. The original cost of the laptop is $900.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Let the original cost of the laptop be represented by x.

Given that you saved $180 on your new laptop, which is a 20% saving from the original price. Therefore, the percentage can be written as,

20% of original price = $180

(20/100) × x = $180

x = ($180×100)/20

x = $900

Hence, the original cost of the laptop is $900.

Step-by-step explanation:

In a graph, you have two points, Y, and X. In math, you will see (x,y) and in division, y/x = rise/run. In this case, Y is the rise, or the standing line, and the run (x), is the sitting line. Rise over run means 2/4, or, 1/2. Hope this helps :)

In the case of (x,y) on a graph chart, the dot would be (4,2) on the graph.

An inflatable pool has sprung a leak. You place a 12-ounce cup under the leak and find that it fills
up in 50 seconds. How many gallons per hour is the swimming pool losing?

Answers

Answer:

6.75 gallons lost in 1 hour.

Step-by-step explanation:

1 US gallon = 128 ounces.

12 ounces takes 50 seconds.

x ounces takes 3600 seconds (which is 1 hour) Cross multiply

12 * 3600 = 50 x

43200 = 50 x Divide by 50

43200 / 50 = x

864 oz = x

So in 1 hour 864 ounces were lost.

Now there are 128 ounces in a gallon

1 gallon /128 ounces = x / 864 Cross multiply

864 * 1 / 128 = x

6.75 = x

There are 6.75 gallons in 1 hour

Step-by-step explanation:

Given

[tex]V_1 = 200ml[/tex] -- To glass 1

[tex]V_2 = 250ml[/tex] --- To glass 2

Required

The final change to the carton

To do this, we simply add V1 and V2

So, we have:

[tex]Total = V_1 + V_2[/tex]

[tex]Total = 200ml + 250ml[/tex]

A gas measuring 525 mL is collected at 104.66 kPa. What volume does this gas
occupy if the pressure is increased by 25 kPa?

Answers

Recall the ideal gas law:

P V = n R T

where

P = pressure

V = volume

n = number of gas molecules

R = ideal gas constant

T = temperature

If both n and T are fixed, then n R T is a constant quantity, so for two pressure-volume pairs (P₁, V₁) and (P₂, V₂), you have

P₁ V₁ = P₂ V₂

(since both are equal to n R T )

Solve for V₂ :

V₂ = P₁ V₁ / P₂ = (104.66 kPa) (525 mL) / (25 kPa) = 2197.86 mL

A helicopter hovers 1100 The above a small island the figure shows the angle of depression from the helicopter to point P is 46° how far off the coast to the nearest foot is the island?

Answers

Answer:

1232 ft

Step-by-step explanation:

Draw a right triangle. Label the height of the triangle. as 800 since the height of the triangle represents the height of the helicopter above the coast of the island. Label the base length of the triangle as d to represent the distance between the coast of the island and the coast of the mainland, P. The angle of depression from the helicopter to point P is 33° so draw a horizontal dotted line at the location of the helicopter and label the angle made by the horizontal line and the hypotenuse of the right triangle as 33°. The angle of elevation from P to the helicopter and the angle of depression from the helicopter to point P are congruent alternate interior angles so label the angle at P as 33°.

The side labeled 800 is opposite of P and the side labeled d is adjacent to P so you can use tangent to write an equation. Solve this equation for d and round to the nearest whole number.
