A bus left Town A at 10:00 am, driving at an average speed of 70 mph. At 12:15 am, the truck reached Town B.

a) What is the distance between Town A and and Town B?

b) How long would it take the truck to drive from Town B to Town A at an average speed of 50 mph?

Answers

Answer 1

Answer:The important formula to this problem is  or

Now, the speed of the car is 70 km/h, and the speed of the truck is 50 km/h. It will take the two vehicles the same amount of time to meet since they both left at the same time. So, since distance equals rate times time, and t = time:

the distance of the car = 70t

the distance of the truck = 50t

Because they both left in opposite directions, and the towns are 420 kilometers apart, the equation for this would be

We now solve the equation.

It will take the vehicles 3 and a half hours to meet. Since we're looking for the time, 3 and a half hours from 10:00 AM is 1:30 PM.

So, the car and the truck will pass each other at 1:30 PM.

A polar bear travels across the snow at a rate of 25 miles per hour. Which representation shows the distance a polar bear can travel at this rate?

A. y = x + 25
B. y = 25x
C. y = x - 25
D. y = 1/25x

Answers

Answer: B

Step-by-step explanation:

Y (distance) is 25 multiplied by x

x is how many hours

so if we make x hours,

25x = y

B is the answer because x represents the hours. We know that 25 is how many miles the bear can travel per hour. Therefore, y = 25x

What should be done to solve the following equation?

x - 9 = 13

Add 9 to both sides of the equation.
Subtract 9 from both sides of the equation.
Subtract 13 from both sides of the equation.
Add 9 to the left side of the equation.

Answers

add 9 to both sides. if you’re trying to find x you need to isolate it and in doing so you have to reverse the -9 by adding 9
if you are trying to find x, you add nine to both sides of the equation.

Find the period.
Principal = 9300 rupees
Annual rate of interest = 13%
Total amount = 17,763
Period = _____ years

Answers

Answer:

The Time period of the Amount is 5 years 3 days .

Step-by-step explanation:

Given as :

The principal = p = Rs 9300

The annual rate of interest = r = 13%

The Total amount after t years = A = Rs 17,763

Let The time period = t years

From Compound Interest method

Amount = principal ×  

Or, A = p ×  

Or, Rs 17,763 = Rs 9300 ×  

Or,  =  

or, 1.91 =  

Taking Log both side

1.91 = (   )

or, 0.2810 = t × 1.13

or, 0.2810 = t × 0.0530

∴ t -  

I.e t = 5.30 years

So, The time period = t = 5 years 3 days

Hence The Time period of the Amount is 5 years 3 days

Who developed the atlatl as a new weapon Help this is super confusing A similarity between Woodrow Wilson and Theodore Roosevelt was that both Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below (numbers have been slightly modified for the purposes of this worksheet).Field Data SummaryCollecting Site Substrate Color Number of Mice Phenotype Light Dark1 Dark 22 3 192 Light 80 74 63 Light 22 19 34 Dark 28 3 255 Light 58 25 336 Dark 65 9 561.

Which fur color seems to have the greatest overall selective advantage? Use data collected from both dark-colored and light- colored substrates to support your answer.6.What environmental change gave a selective advantage for one coat color over another?7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
