Topic: Percentage

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.

Answers

To solve this problem, let's denote the mass of the dog as D and the mass of the lion as L.

We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:

0.80D = 0.24L

We are also given that the mass of the lion is 105 kg more than the mass of the dog:

L = D + 105

We can use these two equations to find the values of D and L.

Substituting the value of L from the second equation into the first equation:

0.80D = 0.24(D + 105)

Now, let's solve for D:

0.80D = 0.24D + 0.24(105)

0.80D - 0.24D = 25.2

0.56D = 25.2

D = 25.2 / 0.56

D ≈ 45

Now that we have the value of D, we can find the value of L by substituting it back into the second equation:

L = 45 + 105

L = 150

Therefore, the total mass of the dog and the lion is:

D + L = 45 + 150 = 195 kg

So, the total mass of the dog and the lion is 195 kg.

Person above is correct

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

I hope this helps!

What is the natural phenomenon that will be explained? or What do we see in nature because of this story? What did the character learn that relates to the nature?
(Ares god of war)

Answers

Answer:

“These phenomena, like all others, demand an ultimate exposition of the truth.” This innocuous passage from a 22 March 1930 review in Nature of the book Growth and Trophic Movements of Plants by Jagadis Chandra Bose caught Gregory’s eye: it shared his vision of science as the search for a deep connection with the absolute truth. The review’s 26-year-old author, Lionel John Farnham Brimble (pictured) — Jack to his friends — was duly asked to join the Nature team as an assistant editor in 1931. Like Gregory, Brimble had earlier passed over a career in research to be an educator and communicator of science, and he flourished in the Nature office. In the late 1930s, he actively pushed for schools to teach biology, particularly his speciality of botany, which was previously taught only to girls in Britain.

Step-by-step explanation:

45.4 + 56.3+ 46x = 2,878
what is x?

Answers

Answer:

Step-by-step explanation:

Combine like terms.

101.7 + 46x = 2878

Subtract 101.7 from both sides.

46x = 2776.3

Divide both sides by 46.

x is about 60.3543478

Rounded to nearest whole number: 60

Rounded to nearest tenth: 60.4

Rounded to nearest hundredth: 60.35

Rounded to nearest thousandth: 60.354

Answer: x = 60.4

Just combine like terms, and subtract the 56.3 and divide

45.4 + 56.3 + 46x = 2878

101.7 + 46x = 2878

-101.7 -101.7

46x = 2776.3

Divide both sides by 46

X = 60.4

The answer is 1, 5/12, and 2/3.

It is 1 because the event that it lands on a section must be 1.

It is 5/12 because we could pick any 5 sections and the event it would be one of them is 5/12.

It is 2/3 for the same logic as 5/12 because 2/3 = 8/12.

It is not 3/8 because you can not have a decimal of a possibility, that is not possible, and it is not 13/12 because you cannot have a higher probability than 1, since it is not possible for there to be 13 winning possibilities out of 12.
