What decimal fraction is 7 hens out of 21 hens?​

Answer: whatever do I care

Step-by-step explanation: I don’t care

The required volume of the pyramid is, 22500 cubic cm.

Volume is referred to as the area occupied within an object's three-dimensional space.

Given that,

The length of cuboid = 90 cm

Width of cuboid = 50 cm

And height of cuboid = 225 cm

Let the height of the pyramid is x cm

Since the height of cuboid and pyramid = 240 cm

⇒ 225 + x = 240

⇒ x = 15 cm

Since the base of pyramid will be the same as the base of cuboid,

The volume of pyramid = 1/3 x base area x height

                                       = 1/3 x 90 x 50 x 15

                                       = 22500

The volume of the pyramid is 22500 cubic cm.

Answer:

$157.5

Step-by-step explanation:

Given that:

Number of hours worked after the school = 1.5 hours

Earnings per hour = $3.50

Earnings for one day or 1.5 hours = 1.5 \times 3.50 = $5.25

Earnings for 5 days or a week = Number of days [tex]\times[/tex] Earnings for 1.5 hours = 5 [tex]\times[/tex] 5.25 = $26.25

Number of weeks for which Ob works = 6

Total earnings in 6 weeks = Number of weeks [tex]\times[/tex] Earnings in one week = Number of weeks [tex]\times[/tex] Earnings in 5 days

Total earnings in 6 weeks = 6 [tex]\times[/tex] $26.25 = $157.5

Answer:

20% or .2

Step-by-step explanation:

First divide 240 by 300

240/300

this gives you .8, you would then subtract that from 1 to get .2

You can check your answer by multiplying 300 by .2

300*.2

this gives you 60 which is the difference between the 2 numbers

Answer:

Step-by-step explanation:

y = -5x

When x = -2 ; y = -5* (-2) = 10   ;  (-2 , 10)

When x = -1   ;   y = -5 *(-1) = 5   ;    (-1 , 5)

When x = 0  ,     y = 0               ;     (0 , 0)

When  x = 1  ;     y = -5 *1 = -5    ;     (1 , -5)

When x = 2 ;     y = -5 *2 = -10   ;     (2 , -10)

Mark these points (-2 , 10) ,  (-1 , 5) , (0 , 0) , (1 , -5) , (2 , -10) and join them.

When you work out 4 oranges and 4 apples divided by 10 youll get 2 and a makes it a loss and also when you work out b its still a loss and there is a solution to the problem so it has to be c in my opinion.

Answer:

im pretty sure its 144.5

When Reena bought a jacket for $45 and after six months later she sold it for $34.65, then the percentage loss is 25%

Given,

Reena bought a jacket for = $45

Selling price of jacket = $34.65

Here, selling price is lower than cost price, so we can consider it as loss

We know,

Loss percentage = (Loss / Initial cost)×100

Loss = Initial cost - Selling price

Loss = 45 -34.65= $10.35

Loss percentage =[tex](\frac{10.35}{45}) 100[/tex]

=0.25×100

=25%

Hence, when Reena bought a jacket for $45 and after six months later she sold it for $34.65, then the percentage loss is 25%

Please find the image file of the question in the attachment.

In the given question, it will take approximately 2-3 min to climb 1 step taller. It's an estimate of 7.92 hours, if you split 950 to 2, it is the period it would take you to go out in minutes when we turn 475 mins into minutes. As we see it will take them an extra 92 mins for 950 feet to ascend. They can achieve it by ascending this at an average rate of 135.7 ft/h.

Answer:

No, the amount of minutes to climb up 1 foot of the height would be around 2-3 minutes. If you divide 950 with 2, you get 475 which would estimate to 7.92 hours. So as we see they would need an extra 55.2 minutes to climb the full 950 feet.

Step-by-step explain

6+9=15

Answer:

53.8 mm

Step-by-step explanation:

Front page and a back page + 400 pages.

The front and back cover are each 0.9mm thick, measured to 1 decimal place.

Total thickness of front and back page = 0.9mm × 2

= 1.8 mm

Each page is 0.13mm thick measured to 2 decimal places

Total number of pages = 400

Total thickness of the pages = Thickness of each page × Total number of pages

= 0.13mm × 400

= 52 mm

minimum thickness of the book = Total thickness of front and back page + Total thickness of the pages

= 1.8mm + 52mm

= 53.8 mm

The minimum thickness of the book is 53.8 mm

Answer:

The height of the Eiffel Tower will be 318 feet.

Step-by-step explanation:

Please check the attached graph.

From the diagram, it is clear that Lizbeth is 5.5 ft tall, seeing the top from 318 feet away, making an angle of elevation to be 72⁰.

The diagram makes a right-angled triangle.

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:

[tex]c=\sqrt{a^2+b^2}[/tex]

[tex]c=\sqrt{5.5^2+318^2}[/tex]

[tex]c=318[/tex] feet

Therefore, the height of the Eiffel Tower will be 318 feet.

Answer:

Step-by-step explanation:

Answer:

x - intercept:  (-22, 0)

y - intercept: (0, 11)

Step-by-step explanation:

Given the linear equation

-3x + 11y = 66

Determining the x-intercept

We know that the x-intercept can be computed by setting the value y=0 and solving for x.

substitute y = 0

-3x + 11y = 66

-3x + 11(0) = 66

-3x + 0 = 66

-3x = 66

Divide both sides by -3

-3x/-3 = 66/-3

x = -22

Thus, the ordered pair representing the x-intercept : (-22, 0)

Determining the y-intercept

We know that the y-intercept can be computed by setting the value x=0 and solving for y.

substitute x = 0

-3x + 11y = 66

-3(0) + 11y = 66

0 + 11y = 66

11y = 66

Divide both sides by 11

11y/11 = 66/6

y = 11

Thus, the ordered pair representing the y-intercept : (0, 11)

Therefore, we conclude that:

x - intercept:  (-22, 0)

y - intercept: (0, 11)

Answer:

X=(-22,0)

Y=(0,6)
