Laiba’s cat catches mice at the rate of 3per day which is the same rate as Irsa’s cat.
What is rate ?Rate is defined as the measurement of a quantity against another to show the difference that exists between the two.
The number of mice caught of Irsa’s cat in 3 days = 9
Therefore in a day = X mice
Make X mice the subject of formula;
X mice = 9/3 = 3
Therefore, Irsa’s cat catches mice at the rate of 3 move per day.
The number of mice caught of Laiba’s cat in 7 days = 21
Therefore in a day = Y mice
Make y mice the subject of formula;
y mice = 21/7 = 3
Therefore, Laiba’s cat catches mice at the rate of 3per day which is the same rate as Irsa’s cat.

You and your friend each deposit $50 in separate savings accounts. Your account earns 4% simple annual interest. Your friend’s account earns 6% simple annual interest. How long does it take for you to earn $12 in interest? How long does it take for your friend to earn $12 in interest?
I need help! Needs answers quick
I can earn simple interest $12 in 6 years and My friend can earn simple interest $12 in 4 years.
What is simple interest?
The principal of a loan or the initial deposit into a savings account serves as the foundation for simple interest. Because simple interest doesn't compound, a creditor will only pay interest on the principal sum, and a borrower will never have to pay interest on the interest that has already accrued.
Principle = $50
Rate of Interest I1 = 4%
Interest = $12.
Interest = [tex]\frac{PNR}{100}[/tex]
=> 12 = [tex]\frac{50\times 4\times N}{100}[/tex]
=> N = [tex]\frac{12}{2}= 6[/tex] years.
Rate of Interest I2 = 6%
=> 12 = [tex]\frac{50\times 6\times N}{100}[/tex]
=> N = [tex]\frac{12}{3}[/tex] = 4 years.
Hence I can earn $12 in 6 years and My friend can earn $12 in 4 years.

Solve the equation below using factorising. 10y² – 11y − 6 = 0 - Give each answer as an integer or as a fraction in its simplest form.
Answer:
y = - [tex]\frac{2}{5}[/tex] , y = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
10y² - 11y - 6 = 0
consider the factors of the product of the y² term and the constant term which sum to give the coefficient of the y - term
product = 10 × - 6 = - 60 and sum = - 11
the factors are - 15 and + 4
use these factors to split the y- term
10y² - 15y + 4y - 6 = 0 ( factor the first/second and third/fourth terms )
5y(2y - 3) + 2(2y - 3) = 0 ← factor out (2y - 3) from each term
(2y - 3)(5y + 2) = 0 ← in factored form
equate each factor to zero and solve for y
5y + 2 = 0 ⇒ 5y = - 2 ⇒ y = - [tex]\frac{2}{5}[/tex]
2y - 3 = 0 ⇒ 2y = 3 ⇒ y = [tex]\frac{3}{2}[/tex]

Answer:
The total discounted price to buy 4 adult tickets, 2 senior citizen tickets, and 3 student tickets is 96$ + 32$ + 18$ = 146$
Step-by-step explanation:
The discounted price for each ticket type is 3/5 of the original price, so for 4 adult tickets the discounted price is 4 * 24 * 3/5 = 96$, 2 senior citizen tickets is 2 * 16 * 3/5 = 32$, and 3 student tickets is 3 * 12 * 3/5 = 18$. Summing these together gives us 96$ + 32$ + 18$ = 146$.

Calculate (-1 + 3i)^5
Step-by-step explanation:
you understand how exponents work, right ?
an exponent defines how often its base has to be multiplied by itself.
so,
(-1 + 3i)⁵
means that
(-1 + 3i)
is multiplied 5 times by itself.
and that means we can split this into sub-multiplication groups like
(-1 + 3i)²×(-1 + 3i)²×(-1 + 3i) = (-1 + 3i)⁴×(-1 + 3i)
the advantage is that squares are easily calculated.
(a + b)² = a² + 2ab + b²
so,
(-1 + 3i)² = (-1)² + 2×-1×3i + (3i)² = 1 - 6i - 9 = -8 - 6i
(-1 + 3i)²×(-1 + 3i)² = ((-1 + 3i)²)² = (-8 - 6i)² =
= (-8)² + 2×-8×-6i + (-6i)² = 64 + 96i - 36 = 28 + 96i
(-1 + 3i)⁵ = (28 + 96i)(-1 + 3i) = -28 + 84i - 96i - 288 =

A. I hope this will be "right"
B. Why does my teacher deceive "me"
C. I don't know how to write a poem and make it "rhyme"
Here you can see that the only word that rhymes with "plight" is "right".
Second, it has to relate to the poem that is given as much as possible.
The letter "A" both rhymes and relates to the given poem.

O 0.90
O 0.00
O 1.20
The correlation coefficient of 0.90 indicates the strongest linear relationship between two variables. It means that there is a strong positive or negative linear relationship between the two variables.
The correlation coefficient is calculated by finding the covariance of two variables, divided by the product of their standard deviations. The formula is as follows:
Coefficient = Covariance(X,Y) / (Standard Deviation of X * Standard Deviation of Y)

Find the growth/decay rate given the exponential function. *
f(x) = 5(1.34)'
The growth/decay rate of an exponential function can be found by taking the derivative of the function with respect to the independent variable.
K in terms of growth and decay?
The growth rate is represented by the constant k. When viewed in terms of exponential DECAY, it is NEGATIVE. The length of time since then is t. If the time information is provided as dates, you must convert it to the amount of time that has passed from the starting point.
Given the function f(x) = 5(1.34)^t, the derivative with respect to t is:
f'(x) = 5(1.34)^t * ln(1.34)
The derivative represents the instantaneous rate of change of the function, and it is also the growth/decay rate.
So the growth/decay rate of the function f(x) = 5(1.34)^t is 5ln(1.34) * (1.34)^t.
In this function, the growth/decay rate is directly proportional to the function value, and it is a constant times the function value. This means that the function is growing or decaying at a constant rate, the rate being 5ln(1.34) which is the coefficient of (1.34)^t.
This constant rate of change is the growth/decay rate. In this case it is a growth rate of 5ln(1.34) which is approximately 1.99.

p and q are integers and p*q denotes the remainder when the product pq is divided by 10. Find a value p, greater than 4, such that p*p = (8*p) + 3
The required value of the given equation is p = √3 + 8.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
If we let x = p - 8, then p = x + 8 and p × p = (x + 8) × (x + 8) = x² + 16x + 64.
We can substitute this expression for p × p in the given equation to get x^2 + 16x + 64 = (8 × (x + 8)) + 3 = 8x + 64 + 3 = 8x + 67.
Subtracting 64 from both sides gives us x² + 16x = 8x + 3, and if we subtract 8x from both sides, we get x² = 3.
The only positive value of x that satisfies this equation is x = √3, so p = √3 + 8.
Since √3 is approximately 1.73, p is approximately 9.73, which is greater than 4.
Therefore, a value of p that satisfies the given equation is p = √3 + 8.
