Answer:

Step-by-step explanation:

In general for fractions

x/y  divided by w/z    

divide the two numerators and divide both denominators in each fraction separately

x/y / w/z    =     x/w  divided by y/z

4/15  /  2/3    =     4/2  /  15/3      =   2/5   <----------------    FINAL ANSWER

since division is the inverse of multiplication

I find it easier to multiple fraction by the inverse of the divisor

4/15  /  2/3    =    4/15  × 3/2    again multiple numerator with numerator and                   denominatior with denominator

4×3  / 15 × 2    =   12 / 30   simplifying ÷ numerator and denominator by 6

= 2/5        which is same value as above

Alan travels eight and two thirds kilometers to get to school. He ran one and ten elevenths kilometers and walked the rest. How
kow [346]

Answer:

6 2/3 or 6 20/30

Step-by-step explanation:

8 2/3 = 8 22/33

1 10/11 = 1 30/33

8 22/33 = 7 52/33

7 52/33 - 1 30/33 = 6 20/30 = 6 2/3

(33 is the common denominator)

hope this helped (:

Vivian found data about her city's population and made a scatter plot the equation of the linebbest fit for. Her data is p= 637.
Andre45 [30]

Answer:

annual growth rate m = 637.5 people / year

Step-by-step explanation:

Solution:-

- The scatter plot displaying the city's population was modeled by a linear equation of the form:

                               y = m*x + c

Where, m and c are constants.

- The scatter plot displayed the following relation of the city's population (p):

                               p = 637.5*t + 198,368.1

Where, p : The population in t years after after 1990

            t : The number of years passed since 1990.

- The slope of the graph "m = 637.5" denotes the rate of change of dependent variable with respect ot independent variable:

                             dp / dt = m = 637.5

- So the rate of change of population per unit time t since 1990 has been constant with a an annual growth rate m = 637.5 people / year

Evaluate the given expression. Subscript 5 Baseline P Subscript 2 a. 40 c. 25 b. 32 d. 20
Leto [7]

Answer:

d. 20

Step-by-step explanation:

The given question implies 5 permutation 2, i.e _{5}P_{2}.

But,

_{n}P_{r} = \frac{n!}{(n - r)!}

So that for _{5}P_{2}, n = 5 and r = 2.

_{5}P_{2} = \frac{5!}{(5 - 2)!}

     = \frac{5!}{3!}

    = \frac{5*4*3*2!}{3*2!}

Cancel out 3 and 2 with respect to the numerator and denominator.

_{5}P_{2} = 5 * 4

     = 20

Therefore,

_{5}P_{2} = 20

So that the correct option is D.
