The shape of Joy’s room is a rectangle 540 cm long by 250 cm wide.

a. Work out the area of his room in Square meters.

b. How much does he pay to buy flooring for his room where flooring costs $ 40 per square meter

Work out the area of his room in Square meters.

We know that:-

Area of a rectangle = (length × breadth)sq.units

Therefore,

Area of the rectangular room = (5.4 × 2.5) square meters

=> Area of the rectangular room = 13.5 square meters.

Area of his room is 13.5 square meters.

How much does he pay to buy flooring for his room where flooring costs $ 40 per square meter

Flooring cost in 1 squre meter = $40

Flooring cost in 13.5 square meters = $(40 × 13.5) = $540

He pays $540 to buy flooring for his room.

Hope this helps you!! (^_^)

Answer: (d)- 1.76 kg

Step-by-step explanation:

Given

The first laptop mass was 11 kg

The rate of mass decreases by 4.7% per year

In 1982, it was

[tex]\Rightarrow 11-11\times 4.7\%=11-11\times 0.047\\\Rightarrow 11(1-0.047)\ kg[/tex]

In 1983, it was

[tex]\Rightarrow 11(1-0.047)-11(1-0.047)\times 0.047=11(1-0.047)^2[/tex]

In 2019 i.e. after 38 years, it is

[tex]\Rightarrow 11(1-0.047)^38=11\times 0.953^{38}=1.76\ kg[/tex]

Answer:

I think what you are asking for is an example.

Step-by-step explanation:

Standard form equation

8x-4y = 20

1. move 8x to the other side

-4y=20-8x

2. divide both sides by -4

[tex]\frac{-4y}{-4} = \frac{20-8x}{-4}[/tex]

3. Solve for this...

y=2x-5

Answer:

probability is 0.67

Step-by-step explanation:

We know that Angle in a circle = 360°

Area of total shaded parts = 60 + 60 = 120°

Area of total unshaded parts = 360-120 = 240°

Probability that a random selected point within the circle falls in the unshaded area

= 240/360

= 2/3= 0.67

Probability that a randomly selected point within the circle falls in the white area will be [tex]0.67[/tex] .

Probability is the ratio of the number of outcomes to the total number of possible outcomes.

Probability [tex]=\frac{Number\ of\ possible\ outcomes}{Total\ number\ outcomes}[/tex]

We have,

Radius [tex]=4[/tex] cm

Now,

Area  of Circle [tex]=\pi r^{2}[/tex]

Area  of Circle[tex]=\frac{22}{7} *4^2=50.28\ cm^2[/tex]

Now,

Area of minor segment [tex]=\frac{\theta}{360^0} *\pi r^{2}[/tex]                                    

Area of minor segment [tex]=\frac{60}{360} *\frac{22}{7}* 4^{2}=8.38\ cm^2[/tex]

Now,

We have two  minor segment,

Area of two minor segment [tex]=8.38*2=16.76\ cm^2[/tex]

Now,

Area of white Portion [tex]=50.28-16.76=33.52\ cm^2[/tex]

Now,

Probability [tex]=\frac{Number\ of\ possible\ outcomes}{Total\ number\ outcomes}[/tex]

Probability [tex]=\frac{33.52}{50.28}=0.67[/tex]

So, the Probability of white area is [tex]0.67[/tex] .

Hence, we can say that Probability that a randomly selected point within the circle falls in the white area will be [tex]0.67[/tex] .

Answer:

Step-by-step explanation:

You are multiplying x² - 4x + 4 and 6x + 3.

This is set up like:

6x + 3(x² - 4x + 4)

To solve this, we want to multiply each term that is outside of the parentheses with each term that is inside of the parentheses.

Let's start with 6x.

6x • x² = 6x³

6x • -4x = -24x²

6x • 4 = 24x

These numbers will be in the first blank row.

Now, let's move onto 3.

3 • x² = 3x²

3 • -4x = -12x

3 • 4 = 12

These numbers will be in the second blank row.

Now let's write all these numbers together.

6x³ - 24x² + 24x + 3x² - 12x + 12

Combine like terms, pay attention to the exponent.

6x³ - 21x² + 12x + 12

Refer to the completed table below.

He is not correct

Step-by-step explanation:

10 x 50 = 500

500 + 10 = 510

510 represents plant 1 height after 50 weeks

8 x 50 = 400

400 + 18 = 418

418 represents plant 2 after 50 weeks

they're not the same height

Answer: No he is not correct

plant 1 will be taller than plant 2 at 50 weeks

do 50 times 10 = 500in

Answer:

it's 25 cm

Step-by-step explanation:

Volume = 225π

or πr²h= 225π

or r²h= 225

or h= 225/r²

here diameter d = 6cm so radius r=d/2 = 3cm

or h= 225/3²

hence h= 25cm

Given:

The recipe calls for [tex]\dfrac{3}{8}[/tex] cup of chili powder.

Karl only wants to use half as much so it won’t be so spicy.

To find:

How much chili powder should Karl use?

Solution:

We have,

Chill power for recipe = [tex]\dfrac{3}{8}[/tex] cup

Chill power used by Karl is half  of chill power for recipe.

[tex]\text{Chill power used by Karl}=\dfrac{1}{2}\times \dfrac{3}{8}[/tex] cup[tex]\text{Chill power used by Karl}=\dfrac{3}{16}[/tex] cup

Therefore, [tex]\dfrac{3}{16}[/tex] cup of chili powder should Karl use.
