The area of a wall in a house is 10.37 square metres. If a can of paint covers 3.1 square metres, how many cans of paint are needed to paint the wall?

Answers

Answer:

4 cans of paint

Step-by-step explanation:

Take the area of the wall and divide by the area that the can of pain will cover

10.37 / 3.1

3.34516129 cans

We need to round up to make sure we buy enough cans of paint

4 cans of paint

We can take area as,

Area = A

The required formula is,

→ A of wall ÷ A that paint's can will cover

Then find the no. of cans of paint that are needed to paint the wall.

Now use the formula,

→ A of wall ÷ A that paint's can will cover

→ 10.37 ÷ 3.1

→ 3.34516129032

→ 4 cans (by nearest value)

Hence, we need 4 cans to paint the wall.

what is 0.000 008 54 in scientific notation please explain perfectly lollll

Answers

Answer:

0.000 008 54 = 8.54 x [tex]10^{-6}[/tex]

Step-by-step explanation:

here is the deal / the rules for scientific notation

1) the number in front of the [tex]10^{x}[/tex] has to be [tex]\geq[/tex] 1 and < 9

that rule is VERY IMPORTANT... [tex]\geq[/tex] 1 and < 9

2) if you move a decimal point to the left the exponent goes up by one

3) if you move the decimal to the right it goes down by one

examples:

314,000,000,000

starting from the right we move the decimal "11" positions to get to

3.14 (notice that I can not stop at 31.4 because that is greater than 10)

so the answer would be 3.14 x [tex]10^{11}[/tex]

your question 0.000 008 54  has to move the decimal SIX positions to

the the right (-6) ...  8.54 x [tex]10^{-6}[/tex]

someone help me please with this algebra problem

Answers

Answer:

7 in.

Step-by-step explanation:

2L + 2W = 16

Try L = 7

2(7) + 2W = 16

14 + 2W = 16

2W = 2

W = 1

If the length is 7 in., then the width is 1 in. That is perfectly acceptable, so L = 7 in. is a good value.

Try L = 8

2(8) + 2W = 16

16 + 2W = 16

2W = 0

W = 0

A length of 8 would make a width of 0. You can't have a rectangle with 0 width, so L = 8 does not work.

When L = 9 or L = 10, the width would be negative. The width of a rectangle cannot be a negative number, so these values doe not work.

Answer: 7 in.

At 2:48, what is the degree measure of the smaller angle formed by the hour and minute hands of a 12 hour clock?

Answers

Answer:

The smaller angle will be "156°".

Step-by-step explanation:

According to the question,

Before 12, the minute hand at 48 minutes:

= [tex]60-48[/tex]

= [tex]12[/tex] (minutes to 12)

So,

= [tex]12 \ minutes+14 \ minutes[/tex]

= [tex]26 \ minutes[/tex]

hence,

The smaller angle will be:

= [tex]26\times 6^{\circ} \ each[/tex]

= [tex]156^{\circ}[/tex]

Answer:

The angle is 204 degree.

Step-by-step explanation:

The angle turned by minute hand in 1 minute is 6 degree

The angle turned by the hour hand in 1 hour is

For the hour hand :

The angle turned in 1 hour = 360/12 = 30degree

At 2 : 00 , the angle covered = 30 x 2 = 60 degree

In each minute the hour hand moves  = 30 degrees / hour  x  1 hour/60 min  

                              = 1/2 degree  

So at 2: 48   the hour hand is at    2*30  + 48 * 1/2 = 84 degrees

For the minute hand:

In each minute it turns = 6 degrees  

So, at 48 minutes the minute hand is at   48 x 6 = 288 degrees

So, the angle between them is 288 - 84 = 204 degrees  

Find the measure of the indicated aces and angles

Answers

Answer:

a=21

b=69

c=42

d=138

Step-by-step explanation:

c is supplementary to d (which is 138), so c=180-138= 42.

angle b is on the edge of the central angle 138, so b is 1/2, therefore, b=69.

angle a is complementary to angle b because any triangle that includes the diameter is a right angle, so angle a=90-69=21.

Suggest methods (other than Cartesian Coordinates) of describing the location of points on a plane.

Answers

Answer:

Step-by-step explanation:

There are two alternative ways of describing the location of points on a plane:

(i) Polar coordinate system (a.k.a. Circular coordinate system).

(ii) Elliptic coordinate system.

Now we proceed to explain briefly the characteristic of each option:

Polar coordinate system: [tex](r, \theta)[/tex]

Where:

[tex]r[/tex] - Distance of the point with respect to origin.

[tex]\theta[/tex] - Direction of the vector between origin and point with respect to the +x semiaxis, in sexagesimal degrees.

The formulae for each component in terms of Cartesian coordinates are described below:

[tex]r = \sqrt{x^{2}+y^{2}}[/tex] (1)

[tex]\theta = \tan^{-1} \frac{y}{x}[/tex] (2)

Elliptic coordinate system: [tex](\mu, \nu)[/tex]

Where [tex]\mu[/tex] and [tex]\nu[/tex] are elliptical coordinates.

The formulae for each component in terms of Cartesian coordinates are described below:

4 t-shirts and a hat costs £26.00
A t-shirt and a hat costs £8.00.
How much does a t-shirt cost?
How much does a hat cost?

Answers

T-shirt $4.00
Hat $10.00
A t-shirt and hat is $8.00 you can divide that by 2 and you get 4. So it will be $4.00
$4.00 times 4 =$16.00 for T-Shirt
So that will mean that the hat is $10.00
And $16.00+$10.00=$26.00

That’s what I got so far
I got
T-shirt: £6
Hat: £2
Lets say t-shirts are ‘a’ and hats are ‘b’
4a + b = 26 and a + b = 8
In an equation:
|4a + b =26
|a + b =8
Now I’m canceling the ‘a’ in the equation so I can solve for b
I’m going to multiply the ‘a’ in the bottom by -4 so if I add it to the ‘4a’ it’ll be equal 0
I can’t only multiply the ‘a’, I have to multiply the whole bottom part:
|4a + b =26
-4 |a + b =8
And now:
|4a + b =26
|-4a -4b =-32
We got rid of the a in the equation
4a-4a=0
b-4b=-3b
26-32=-6
-3b=-6
And b=2
Now we’ll go back to the original equation and replace ‘b’ with its value to solve for ‘a’
|4a + 2 =26 ==> 4a=26-2
|a + 2 =8 ==> a=8-2

4a=24
a=6
Therefore, a T-shirt cost £6 and a hat cost £2.

EC=2, AD=2.4

Step-by-step explanation:

Objectives: Similar Triangles. We need to establish the scale factor of the similar triangles, and use that factor to find the missing side length.

The corresponding similar side of the left triangle is AD and AB. AB measure is 4.5 and AD measure is 1.5 so this means that AB is 3 times as long as AD. This also means that for the other sides of the left triangle as well.

AC is 3 times as long as AEBC is 3 times as long as DE

Using this information and what given in the diagram, AC measure is 3 but we need to find EC measure. We can use the addition postulate to find EC.

AE+EC=AC1+EC=3EC=2

The same can be done for the triangle on the right. AC is 3 times longer than AE, so this means that AB is 3 times longer than AB using that knowledge, AD measure is 2.4

We have the reference angle, the side opposite the reference angle, and we are looking for the side adjacent to the reference angle. This is the tangent ratio: the side opposite the reference angle over the side adjacent to the reference angle. We know the measure of the reference angle and we know the value of the side opposite the reference angle. Filling in:

How do relational databases work mathematically?

Answers

Answer:

A relational database stores data in a series of tables so that the data models a mathematical theory of relations. The model allows for queries based on projection, selection, and join, among other operations, and connects the data in the tables by way of keys.

Answer:

Well, I guess in a formal sense you could call relational algebra a type of logic, which puts it into the realm of ‘math’, though I don’t think most mathematicians would look at it as being a very significant area, more ‘applied logic’ than anything else.

That being said, relational algebra DOES present some formalisms in the shape of relations, tuples, normalizations, and denormalization, etc. There is also a model of sequential operations and thus the underpinnings of the ACID database concept.

Since the overwhelming primary use of RA has been as a way to structure our ideas about SQL RDBMSes there isn’t really a lot of deep theory there. I don’t think anyone has really built any other models of RA beyond an RDBMS. There have been limited non-SQL RDBMS implementations, but AFAIK none of them are really actively maintained today.
