A certain radioactive substance decays from 100000 grams to 1000 grams in 34 days. What's it's half-life ?
Answers
Answer:
Half life of the radioactive element is 5 days.
Step-by-step explanation:
Formula to get the final amount after the radioactive decay in 't' days,
[tex]A_t=A_0e^{-\lambda t}[/tex]
Here [tex]A_0[/tex] = Initial amount
λ = Decay constant
t = duration of decay
[tex]A_t[/tex] = Final amount
[tex]1000=100000e^{-\lambda(34)}[/tex]
0.01 = [tex]e^{-34\lambda}[/tex]
ln(0.01) = [tex]\text{ln}(-e^{34\lambda}})[/tex]
-4.6052 = -34λ
λ = 0.13544
Since, λ = [tex]\frac{\text{ln}(2)}{t_{\frac{1}{2}}}[/tex]
[tex]t_{\frac{1}{2}}=\frac{\text{ln}2}{0.13544}[/tex]
= 5.11
≈ 5 days
Therefore, half life of the radioactive element is 5 days.

mortar is made by mixing water cement and sand in the following ratio 1 : 2 : 3 . how much of each component is needed to make 3kg of mortar
Answers
Answer:
To make 3 kg of water, we need
0.5 kg water
1 kg cement
1.5kg sand
Step-by-step explanation:
Here, we want to calculate the mass of each component needed to make 3 kg of mortar
We work with the ratio
Total ratio is:
1 + 2 + 3 = 6
water
1/6 * 3kg = 0.5 kg
cement
2/6 * 3 kg = 1 kg
sand
3/6 * 3 = 1.5 kg

The sum of two numbers is 85. The second number is 4 more than 2 times the first number. Let x represent the first number and let y represent the second number. What are the two numbers? Use the table to guess and check.
Answers
Step-by-step explanation:
x+y=85
y=4+2x
[tex]x = 85 - y \\ y = 4 + 2(85 - y) \\ y = 4 + 170 - 2y \\ 3y = 174 \\ y = 58 \\ x = 85 - y \\ x = 27[/tex]

A leopard is running with a velocity of 3 m/s. it then accelerates at 2 m/s² for 4 seconds.
use the formula:
v = u + at
to work out the final velocity of the leopard.
please can people reply and help me thank you
Answers
Using the formula:
v = u + at
Here s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.
In this case, u = 3m/s, a = 2m/s^2, t = 4s and we want to find final velocity, v, s, v = u + at
v = 3 + 2(4) = 11m/s

Ten baseballs and four ping-pong balls cost $46. One baseball costs one dollar more than two ping-pong balls. Find the cost of one baseball and the cost of one ping-pong ball.
Answers
Answer:
1 baseball cost $4
1 ping pong cost $1.5
Step-by-step explanation:
let the cost of baseball be b and the cost of ping pong be p
10 baseballs = 10b
4 ping pong = 4p
Adding both gives total $46
10b + 4p = 46 •••••••••(i)
baseball costs 1 dollar more than 2 ping pong
b = 2p + 1 •••••••(ii)
Substitute ii into i
10(2p + 1) + 4p = 46
20p + 10 + 4p = 46
24p = 46-10
24p = 36
p = 36/24
p = $1.5
b = 2p + 1
b = 2(1.5) + 1
b = 3 + 1 = $4
20% of the girls in class have blonde hair. 16 girls do not have blonde hair. How many total students
Answers
Since 7 have blonde hair and 9 have glasses, that would be a total of 16 persons if there were no overlap; that is, no blonde wears glasses and nobody who wears glasses is a blonde.
But there are 4 persons who have both blond hair and wears glasses. That means, of the 7 who are blondes, 3 of them do not wear glasses. And, of the 9 who wear glasses, 5 of them are not blondes.
So we have 3 who are blondes without glasses, 5 who wear glasses who are not blondes, and 4 blonds with glasses, for a total of 12 persons.
The probability is, therefore, 12/26 or 6/13.

P(red) :
Required outcome = number of red partitions = 2
Total possible outcomes = total Number of partitions = 6
Hence,
P(Red) = 2 / 6 = 1/3

What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is an expression as -
5 - 3(x + 1) = 2y - 3x + 2
The given expression is -
5 - 3(x + 1) = 2y - 3x + 2
5 - 3x - 3 = 2y - 3x + 2
2 - 3x = 2y - 3x + 2
2 - 3x + 3x - 2 = 2y
2y = 0
y = 0
y = 0x + 0
Therefore, we can write the given equation in the form of y = mx + b as -
y = 0x + 0.
