the ages of mother and daughter are in the ratio of 5 : 3 if the age of mother is 50 years find the age of her daughter

netineya [11]

Answer:

30 years

Step-by-step explanation:

Forming Algebraic expressions and solving them to find the age.

Ratio of age of mother and daughter = 5 : 3

Age of mother = 5x

Age of daughter = 3x

It is given that mother's age is 50 years.

⇒ 5x = 50

Divide both sides by 5.

x = 50÷5

x = 10

Daughter's age = 3x

= 3*10

= 30 years

Question:

kolbaska11 [484]

Answer:

<u>Proportional relationship formula:</u>

y = kx, where k is the constant of proportionality

Use one of the ordered pairs to calculate the value of k

<h3>Company A</h3>

Point (2, 20)

20 = k*2
h = 20/2
k = 10

The equation: y = 10h

<h3>Company B</h3>

Point (3, 20)

20 = k*3
k = 20/3
The equation: y = 20/3h

Company A has greater unit rate as 10 > 20/3

The function f(x) = 25(4)^x represents the growth of a bird population every year in a national park. Kyle wants to manipulate t

Natasha_Volkova [10]

$f(x)=25(4)^{\frac{x}{2}}$ will be the function to calculate population every half year.

Further explanation:

The given formula is:

$f(x) = 25(4)^x$

In the given formula, x represents the amount of time in years. So, in order to convert the given function for yearly calculation of population, to find the population every half year the time will be converted into half. This means that instead of x, x/2 will be used.

So the new function will be:

$f(x) = 25(4)^{\frac{x}{2}}$

A navigator plots the course a plane is currently traveling. The plane is 300 miles from its destination. If it continues on its

inna [77]

We have to use the rule of cosx° to solve this problem. Attached is a diagram of the navigator's course for the plane. It is similar to the shape of a triangle. We know the plane is 300 miles from its destination, so that will be one of the sides. On the current course, it is 325 miles from its destination, so that will be another one of the sides. The last side is 125 because that is the distance between the destination and the anticipated arrival. Cosx° is what we are looking for.

To find how many degrees off course the plane is, we must use the rules of Cosx°, which is shown in the attached image.

The plane is approximately 23° off course.
