Answer: 40%
Step-by-step explanation: 1 Divided by 2.5 is 0.4, or 40%.
The number decreased by 150%
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here a number becomes 2.5 times smaller than let the number be x then the value of the number the decrease is = x - 2.5x
= -1.5x
Thus the percentage decrease is = -1.5x/x × 100
= - 150%
Hence, The number decreased by 150%

I need 3 reasons why it is important to keep gorillas from becoming extinct. I'll give brainliest. I know that this isnt math but more people answer questions that are in math so... yea
Answer:
1. gorillas are able to spread the seeds of larger fruits that other, smaller animals are incapable of consuming. When gorillas consume a fruit and later expel the seeds, they are helping to perpetuate diverse, supportive ecosystems.
2. The forest will never be same if the gorillas are gone. Illegal coltan mines (minerals used in smart phone and computer production) are controlled by militia in the gorilla habitat (DRC) and contribute to habitat destruction and poaching.
3. Many local indigenous tribes and communities living alongside the gorilla habitat consider the gorillas to be their patron gods. The Kisimba clan (Bahumba) believe they descended from the gorillas. Their traditional tale tells a story of a gorilla rescuing a man that was lost and stuck high up in a tree. To save the man, a gorilla climbed up the tree and gently placed him on his silver back before carrying him back to safety.
Step-by-step explanation:
Ultimately we cant let gorillas go for much more reasons then just these 3 and they are used for so much in all of their respected environments.
How many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel? Which of the following equations could be used to solve this?
Answer:
3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.
Step-by-step explanation:
To determine how many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel, the following calculations must be performed:
50 + 0.62X = 78
0.62X = 78 - 50
0.62X = 28
X = 28 / 0.62
X = 45.16
100 - 45.16 = 54.84
54.84 = 4
45.16 = X
45.16 x 4 / 54.84 = X
180.64 / 54.84 = X
3.29 = X
Therefore, 3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.
Answer:
C
Step-by-step explanation:
a(0.62)+4(1.00)/a+4+78/100

Answer:
Number cube: 1/6 Tossing tails on a coin: 1/2

Answer:
29: 81.5
30: 9
31: 180
Step-by-step explanation:
29: if c=9 then squared then it is 9 times 9 which equals 81 then a equals 1/2 which is 0.5 in fraction so we add 81 + 0.5 =81.5
30: c equals 9 which we times by 2 and equals 18 then we times 18 by a which is 0.5 and it goes back down to 9
31: b equal 15 and it is squared so we times 15 by 15 which equals 225 and then we multiply 5 times c and c is 9 so 5 times 9 is 45 and 225 minus 45 equals 180
