Answer:

15. a 7.9 miles

b. NO .

Step-by-step explanation:

From the table, on

Monday = 3 2/5

Wednesday = 4 1/2

Write the distance in improper fractions as;

Monday = 17/5

Wednesday = 9/2

Find the sum as

$\frac{17}{5} +\frac{9}{2} =\frac{34+45}{10} =\frac{79}{10}$

where the L.C.M is 10

Answer is 7.9 miles

Distance covered on Thursday and Saturday will be

2 2/6 + 3 3/4

14/6 + 15/4 ------the L.C.M is 12

(28+45)/12

73/12

The distance 73/12 miles for Thursday + Saturday is less than that of Monday + Wednesday 79/10 miles. The answer is NO.

Find the percent of increase or decrease? 2.5y to 1.5y

horsena [70]

Answer:

From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.

Step-by-step explanation:

Here, the initial value = 2.5 y

The final value of 1.5 y

Now,as Final Value < Initial Value

So, there is a DECREASE IN THE VALUE.

Now, decrease in the value = Initial value - Final Value

= 2.5 y = 1.5 y = 1 y

or, there is a decrease of ( 1 y) in the given value.

Now, Percentage decrease in the value is given as:

$\textrm{Percentage Decrease} = \frac{\textrm{The decrease in the value}}{\textrm{The initial Value}} \times 100\\ = \frac{1 y}{2.5 y} \times 100 = 40$
