. A honeybee leaves the hive, traveling at a speed of 4 mph and returns 1 hour later. What was the distance traveled and the displacement of the honeybee in miles?

Answers

Answer:

4miles

Step-by-step explanation:

Step one:

given

speed, v= 4mph

time taken t=1 hour

The velocity is defined and the rate of change of displacement

Required:

Distance traveled

we know that the expression relating distance, velocity and time is

velocity= distance/time

distance= velocity* time

substitute we have

Distance=4*1

Distance= 4miles

The distance traveled and the displacement of the honeybee in miles  4miles

2(x-2)-5=3-2x+6​

Answers

Answer:

x=9/2

Step-by-step explanation:

First distribute 2

2x-4-5=3-2x+6

Add the like terms on the left side -4-5=-9

2x-9=3-2x+6

Do this with the right side 3+6=9

2x-9=-2x+9

Add 9 from the left side to the right side

2x=-2x+18

Then add 2x from the right side to the left side

4x=18

Divide 4 from both sides

x=18/4 or 9/2

Answer:

9/2

Step-by-step explanation:

2x-4-5= 3-2x+6  distribute 2 through the parentheses

2x-4-5=9-2x     add the numbers

2x-9=9-2x calculate the difference

2x+2x-9= 9  move variable to left side and change sign

2x+2x= 9+9 move constant to right side and change sign

4x= 18  collect like terms

x=9/2 divide both sides by 4

Step-by-step explanation:

subtract 19 to both sides

10-19=(-9)

n=-9

to verify add 19+(-9)=10

hope this helps :3

if it did pls mark brainliest

n = -9
10 = n + 19
n + 19 = 10

Angle ABC has a measure of 125° Angle ABC is rotated 75° about point B to create angle A'B'C'. What is the measure, in degrees, of angle A'B'C

Answers

Answer:

m∠A'B'C' is 125°

Step-by-step explanation:

The given parameters are;

The measure of ∠ABC = 125°

The form of transformation applied to ∠ABC = 75° rotation about the point B

Given that a rotation of a geometric figure is a form of rigid transformation, the distance between the coordinates of the points in the preimage are equal to the distance between the coordinates of the points on the image;

Therefore, the angle formed by the ray AB and CB and the angle formed by the ray A'B' and C'B' are equal

From which we have;

m∠ABC = m∠A'B'C' = 125°

The Extreme Rock Climbing Club planned a climbing expedition. The total cost was $4600, which was to be divided equally among the members going. Prior to the trip,
10 members decided not to go. If the cost per person increased by $230, how many people went on the expedition?

Answers

If you divide the previous cost with the price per person, you would get the number of people who was previously planned to be going, which is 20. That said, with 10 people not going, there would be 10 people left with the price of 2300 to continue the expedition

Let x = number of people that were supposed to go to the trip, where x is greater than or equal to 0.

Let y = price per person initially with x people going on the trip.

xy = 4600

Solve for y.

y = 4600/x

(x - 10)(y + 230) = 4600

Replace y with the fraction 4600/x.

(x - 10)[(4600/x) + 230)] = 4600

What you need to do:

1. Solve (x - 10)[(4600/x) + 230)] = 4600 for x.

2. When you find x, subtract 10 from the value of x to find the number of people that went on the expedition.

You finish.

Ariana borrows $200 on a 6-year loan.She is charged 5% simple interest per year.How much interest is she charged for 6 years?What is the total amount she has to pay back? PLS HELP

Answers

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Principal (P)= $200

Interst rate (r)= 0.05

Time (t)= 6

First, we need to calculate the total interest using the following formula:

I= P*r*t

I= 200*0.05*6

I= $60

Now, the total debt:

Total debt= P +I

Total debt= 200 + 60

Total debt= $260
