takes her 20 minutes to walk 1/2 a mile  

2 miles=80 minutes  

1/4= 10 minutes i think  

so 80+10=1 1/2

Step-by-step explanation:

Velocity = distance/time

1/3 h=20m

V=0.5/20=0.025m/m

So time= distance/velocity

T=2.25/0.25=90m

90m= 1.5h

I did it also by logic by using these steps:

1/2*(1/2 mile in 1/3 hour) = 1/4 mile in 1/6 hour

we have 9 quarter in 2 1/4

So 1/6 * 9 =1.5h

hope this helps !

The population of bacteria can be modeled by the function below, where t represents the time since the population started decayi
Oksana_A [137]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. I will assume the function is:

f(t) = 15(0.86)^t

Required

Determine the rate of decay

In an exponential function f(x) = ab^x,

The decay rate of the function is calculated as:

1 - r = b

By comparison:

b = 0.86

So, the equation becomes:

1 - r = 0.86

Make r the subject

r = 1 - 0.86

r = 0.14

<em>The rate of decay is 0.14</em>

An educator believes that new reading activities for elementary school children will improve reading
Damm [24]

The correct answer to this open question is the following.

Unfortunately, you forgot to attach the scores shown in the back-to-back stem-and-leaf display. So we do not know what the numbers are and we do not have any reference at all

What we can do to help you is to comment on the following general terms.

There have been previous and similar experiments or projects like this in other schools in America. These results suggest that the new activities are better because extra or special reading comprehension programs better prepare students to understand what they are reading and comprehend more than basic ideas of the text.

Students that participate in these programs develop a better sense to understand and like what they are reading, considerably increasing their focus and attention.

These programs have resulted positively when trying to improve the marks of the students, compared to other traditional approaches.

*The rectangle to the left is divided into 12 shapes. One of them is a rectangle labeled with #1 and the remaining 11 shapes are
Mandarinka [93]

Given that the length of side of shaded area is 1 ft.

Making equal square of size of shaded area we have:

Horizontally number of shaded area are 12

Vertically number of shaded area are 11

So, the horizontal length of big rectangle is 12 ft.

The vertical length of big rectangle is 11 ft.

Area of big rectangle is 12*11

Area of given rectangle is 132 sq.ft.
