Answer:

Below

Step-by-step explanation:

m = motorcylce speed

c = car speed = 2m-30

   difference in speeds =   2m-30 - m = m-30

      in two hours this speed accumulates 20 miles (rate * time = distance)

                    2 (m-30) = 20

                     2m - 60 = 20

                         m = 40     then c = 2m-30 = 50    mph

Answer:

9 : 4

Step-by-step explanation:

Ratio:

Find the quantity of yellow and red dye in the mixture.

 Yellow : Red = 9 : 2

 Total share = 9 + 2 = 11

    [tex]\sf \text{Quantiy of yellow} = \dfrac{9}{11}*44[/tex]

                                 = 9 * 4

                                = 36 litres

      [tex]\sf \text{Quantity of Red}= \dfrac{2}{11}*44[/tex]

                                  = 2 * 4

                                  = 8 litres.

Now, 8 litres of red dye is added.

New quantity of red dye = 8 + 8 = 16 liters.

New ratio of Yellow to red = 36 : 16

                                             = (36÷4) : (16÷4)

                                             = 9 : 4

The number represented in the statement is 7

The statements in the question can be highlighted as:

When represented as an equation, we have

5(3x - 10) = 55

Where x represents the number

Divide both sides by 5

3x - 10 = 11

Add 10 to both sides

3x = 21

Divide by 3

x = 7

Hence, the result is 7

If It is estimated that the sanctuary can sustain up to 600 deer. Absent constraints, the population would grow by 70% per year. After one year is 85 and after two years is 144.50.

Using this formula

A = P(1+r)t

Where:

A = Amount

P = Principal

r =Interest rate

t = time

Let plug in the formula

After one year:

A = 50(1+0.70)^1

A = 50(1.70)^1

A= 85 deer

After two years:

A = 50(1+.70)^2

A = 50(1.70)^2

A = 50(2.89)

A = 144.50 deer

Answer:50%

Step-by-step explanation:

The number of notes of Rs. 100 is 1000, Rs. 50 is 1500, and Rs. 10 is 2500.

The ratio describes the number of times one number contains another. It helps to establish a relationship between two or three quantities.

The ratio between any two quantities is described as a:b. This can also be written as a to b or a/b.

The ratio of RS.100, RS.50, and RS.10 is 2:3:5.

The population of the deer in year 2018 would be 11971.

Given,

In the question:

The model is used to estimate the deer population in a region, where x is the number of years after the year 2009. Using the model, estimate the deer population in the year 2018

Model is given as:

P = 2,3201 [tex](1.2)^x[/tex]

Now, According to the question:

The number of years from 2009 to 2018 = 9

Here, the equation that shows the deer population after x years since 2009,

P = 2,3201 [tex](1.2)^x[/tex]

Substitute x=9 in the above equation,

The number of people who do not like any of the three colour is 5, using the set theory.

What is Set theory?

A subfield of mathematics called set theory studies sets and their characteristics. Set theory's fundamental ideas are straightforward and seem to stand on their own. The set theory appears to be straightforward, but it is actually a very complex topic. Mathematicians have specifically demonstrated how almost all mathematical ideas and conclusions may be formalized within the theory of sets. This is regarded as one of the pinnacles of contemporary mathematics. Given this accomplishment, it is possible to assert that set theory serves as the foundation for mathematics.

In the given question, we have:

Total number of people in the survey = 25;

Number of people like red = 13;

The number of people who like blue = 8;

The number of people who like yellow = 13;

5 people like both Red & Blue,

4 people like both Blue & yellow,

7 people like both Red & Yellow

2 people like all three colors.

Let n be the number of people who do not like any of the three colour.

Using the concept of set theory, we can write it as:

3 + 4 + 1 + 5 + 2 + 3 + 2 + n = 25;

⇒20 + n = 25;

n = 25 - 20

n = 5;

The future value of an investment with such details must have a present value of $11120.58

Present value (PV) formula finds application in finance to calculate the present day value of an amount that is received at a future date. The present value formula (PV formula) is derived from the compound interest formula. The compound interest formula is,

FV = PV(1 + r/n)^nt

We can substitute the values into the formula

15000 = PV(1 + 0.06/12)^12*5

15000 = PV(1.005)^60

The equations that represent the circle having a diameter of 12 units and a center lying on y-axis are; x² + (y – 3)² = 36, and x² + (y + 8)² = 36.

The standard form of the equation of a circle is (x - h)² + (y - k)² + r², where (h, k) is the center of the circle, and r is its radius.

We have given that circle having a diameter of 12 units, will have a radius of 12/2 = 6 units. Thus, r = 6.

Since we know that circle having the center on the y-axis will have a center as (0, k) as all points on the y-axis have x-coordinate 0.

Thus, the equation of the circle, with a diameter of 12 units is;

x² + (y - k)² = 6², or,

x² + (y - k)² = 36.

From the given options, the equations x² + (y – 3)² = 36, and x² + (y + 8)² = 36, are correct.

Thus, the equations that represent the circle having a diameter of 12 units and a center lying on y-axis are; x² + (y – 3)² = 36, and x² + (y + 8)² = 36.

In this case, the roots (zeros) are at X =-7 and x = 5

Then we can write:
