We know that there are 99 students in total. He already entered the marks of 9/11 of the students. We need to find out how many students’ marks have not been entered yet.

We can multiply 99 by 9/11. This gives us 81. We now need to subtract 99 from 81. This gives us 18.

He has not entered the marks of 18 students.

A rectangular box is 1m long and 75 cm high. if the volume of the box is 375000cm³,find the width of the box ​

Answers

Answer:

width = 50 cm

Step-by-step explanation:

The volume (V) of a rectangular box is calculated as

V = lwh ( l is length, w is width and h is height )

Since V is given in cm³ then dimensions must be in cm

l = 1 m = 100 cm , then

100 × w × 75 = 375000

7500w = 375000 ( divide both sides by 7500 )

w = 50

the width of the box is 50 cm

Given the following sequence:

2, -8, 32, ...

What is a geometric sequence?

A geometric sequence can be defined as a series of real and natural numbers that are generally calculated by multiplying the next number by the same number each time.

Mathematically, a geometric sequence is given by the expression:

[tex]a_n =a_1r^{n-1}[/tex]

Where:

r is the common ratio.a is the first term of a geometric sequence.

Substituting the given parameters into the formula, we have;

[tex]a_{12} =2 \times -4^{12-1}\\\\a_{12} =2 \times -4^{11}\\\\a_{12} =2 \times -4194304[/tex]

h=vertical altitude and

a=side length of the base

[tex]85=5^2+(2*5)\sqrt{\frac{25}{4}+h^2}[/tex]

A spinner is shown.
Red
Violet

Green
The spinner arrow is spun 150 times
Ahout how many times will the spinner arrow stop on Blue or Green?

Answers

Answer:

43

Step-by-step explanation:

Total number of different colors = 7

Probability of spinner landing on blue = 1/7

Probability of spinner landing on green = 1/7

Probability of spinner landing on blue OR green = 1/7 + 1/7 = 2/7

if the spinner is spun 150 times,

Number of times spinner will land on green or blue = Probability of spinner landing on blue OR green x 150

= 2/7 x 150

= 42.85714...

= 43 (rounded to the nearest whole number)

Answer:

Approximately 43 times

Step-by-step explanation:

Number of sections is 7

Probability of each section is 1/7

Probability of blue or green:

P(blue or green) = 2*1/7 = 2/7

Spinner nun 150 times, number of stops on blue or green:

N = 2/7*150 = 42.86 ≈ 43 (rounded up)

If a plane can travel 480 miles per hour with the wind and 420 miles per hour against the​ wind, find the speed of the wind and the speed of the plane in still air.

Answers

a. The speed of the wind is 30 mph

b. The speed of the plane in still air is 450 mph

Let

V = speed of plane in still air and v = speed of wind.The required equations

Since the plane can travel 480 miles per hour with the wind, we have that

V + v = 480 (1)

Also, the plane travels 420 miles per hour against the​ wind, we have that

V - v = 420 (2)

a. Speed of the wind

The speed of the wind is 30 mph

subtracting equations (1) and (2), we have

V + v = 480 (1)

-

V - v = 420 (2)

2v = 60

v = 60/2

v = 30 mph

So, the speed of the wind is 30 mph

b. Speed of the plane in still air

The speed of the plane in still air is 450 mph

Substituting v into equation (1), we have

V + v = 480 (1)

V + 30 = 480

V = 480 - 30

V = 450 mph

So, the speed of the plane in still air is 450 mph

Answers

The number of cans that can be recycled in 16 days, written in scientific notation is 2.6 x 10⁹.

What are Scientific notations?

The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5x 10¹².

Given to us

Average 113,204 aluminum cans are recycled in a minute.

Firstly, in order to find the number of cans that can be recycled in 16 days, we need to find the number of minutes in 16 days. we know that 1 day has 24 hours where each hour has 60 minutes. therefore,

Number of minutes in 16 days = 16 x 24 x 60

Number of minutes in 16 days = 23,040 minutes

As it is given that on an average 113,204 number of cans can be recycled in a minute, therefore,

Total number of can that can be recycled = 113,204 x 23,040

                                                                      = 2,608,220,160

                                                                       = 2.6 x 10⁹

Hence, the number of cans that can be recycled in 16 days, written in scientific notation is 2.6 x 10⁹.

But the costs involved in piping the suns energy into the electricity grid remain prohibitively high. Now, solar power could get the efficiency boost it needs, thanks to a corporate takeover.Last week, Tesla, which makes batteries big enough to power your home and also happens to make the biggest-selling electric car. Last week, the company announced that it is buying SolarCity, one of the leading installers of solar panels in the US. Elon Musk, who co-founded both Tesla and SolarCity, could provide the breakthrough the fledgling solar industry needs.The price of solar panels has fallen significantly in the last decade, but providing stable power from solar is more complex than just plugging in more panels. Grid operators need a way to store the suns energy to smooth out the supply during the night and when its cloudy.The Solana solar power plant in Gila Bend, Arizona, pumps excess heat energy into huge vats of salt. These vats are good at absorbing heat. When the energy is required, piping water through the salt causes it to boil and produce steam that drives a turbine. In Texas, a giant array of batteries backs up the Notrees wind farm. This backup keeps energy flowing when the wind dies.Both projects turn unreliable renewable resources into dependable power plants. Doing this is at a cost. While deployment of storage is increasing, it is not widespread, says Matt Kromer, who leads the SunDial project at the Fraunhofer Center for Sustainable Energy Systems in Boston.Simply plugging solar panels into a battery isnt enough, says Aminul Huque at the Electric Power Research Institute in Palo Alto, California. Batteries get stressed every charging cycle and die quickly if they arent carefully managed.To get round this, firms are turning to software. Kromer says SunDial taps into various data: electricity demand, weather forecasts, electricity prices, and solar panel and storage system data. The software uses all this information to make better decisions about when to charge and discharge batteries, increasing their lifespan. It can also help energy providers balance supply and demand, ironing out peaks.Tesla and SolarCity could do the same. With batteries in cars and homes that can store solar power for when its needed, Tesla can smooth the supply of solar power to the grid.A similar approach is already being tested in pilot schemes around the US. Arizona Public Service serves the Phoenix area, plugs into the Solana plant, and is in the midst of deploying solar panels and batteries to 1500 households.Even though the panels and storage are spread across many rooftops, they are effectively roped together into a single 10-megawatt power plant that APS can control. The SunDial project is planning a pilot in Massachusetts in which 2 megawatts of solar power and storage are controlled by the local utility company.This kind of integration is exactly what the tie-up between Tesla and SolarCity promises but on a much grander scale.
