Amar cycles at a speed of 18km/h.
It takes him 55 minutes to cycle between two villages.
Calculate the distance between the two villages​

Answers

Answer:

The distance between the two villages is 16.5 Km

Step-by-step explanation:

Constant Speed Motion

It's a type of motion in which the distance of an object changes by an equal amount in every equal period of time.

If v is the constant speed, the object travels a distance x in a time t, given by the equation:

x=vt

Amar cycles at v=18 Km/h for t=55 minutes. We need to calculate the distance traveled between the two villages.

Since the speed and the time are given in different units, we convert the time to hours, recalling that 1 hour=60 minute.

t=55 min = 55/60 hours

For the sake of precision, we won't operate the division so far. Compute the distance:

x=18 *55/60=16.5 Km

Mike bought 8 shares of stock for $57.50 each, hoping that the value would increase. When he sold the shares it was only for $42.75 per share. Which describes Mikes net profit

Answers

Bought 8 shares at 57.50 each = 460 total
Sold shares at 42.75 each = 342

Net profit = revenue - expense

= 342 - 460
= -118

Mike has a net loss of $118 because he sold the shares at a lower price than what he bought them for.

Solve 24>−3r≥−9. please

Answers

Answer:

−8<r≤3

Step-by-step explanation:

The final inequality of 24>−3r≥−9 is -8 <  r ≤ 3.

Given,

24>−3r≥−9

We need to solve this inequality.

What are inequalities?

We have,

< = less than

> = greater than

≤ = less than and equal

≥ - greater than and equal

If we change the sign we change the inequality.

Example:

2 > -1

Multiply -1 on both sides.

-2 < 1

We have,

24 > -3r ≥ -9

We can cancel the common factor.

3 x 8 > -3r ≥ - 3 x 3

8 > -r ≥ -3

Multiply - on all sides.

-8 < -(-r) ≤ -(-3)

-8 <  r ≤ 3

This means r values are between -8 and 3.

r = ( -8, 3]

Thus the final inequality of 24>−3r≥−9 is -8 <  r ≤ 3.

Answers

Answer:

what you do is 9 times what equals 27 well 3 does so you multiple 2/9 by 3/3 and get 6/27

so the answer is 6/27 :)

G/27 = 2/9
G = 27 x 2/9
G = 54/9
G = 6

6/27 = 2/9 (divide 6/27 using 3’s table)

Hello.

The answer is choice A. angle 1 = 118, angle 2 = 118

Explanation:

The four angles above are congruent (meaning the same) to the ones beneath.

Angles 1 and 2 are also congruent, so they will measure the same.

Lets label the angles above A, B, C, D.    B being the known angle, which is 118°. The angles beneath can be labelled E, F, G, H.

∠B ≅ ∠D

Answers

Answer:

3x-y

Step-by-step explanation:

Answer:

Simplifying

5x(2x + y) = 0

(2x * 5x + y * 5x) = 0

Reorder the terms:

(5xy + 10x2) = 0

(5xy + 10x2) = 0

Solving

5xy + 10x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '5x'.

5x(y + 2x) = 0

Ignore the factor 5.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve:

Simplifying

x = 0

Solving

x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying

x = 0

Subproblem 2

Set the factor '(y + 2x)' equal to zero and attempt to solve:

Simplifying

y + 2x = 0

Reorder the terms:

2x + y = 0

Solving

2x + y = 0

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

2x + y + -1y = 0 + -1y

Combine like terms: y + -1y = 0

2x + 0 = 0 + -1y

2x = 0 + -1y

Remove the zero:

2x = -1y

Divide each side by '2'.

x = -0.5y

Simplifying

x = -0.5y

Solution

x = {0, -0.5y}

1. In the diagram below, if m angle1=79^ , find the measure of each numbered angle.

Answers

Numbers 1,4,5,8 will be 79^. Numbers 2,3,6,7 will be 101^.

The measure of angles  ∠1, ∠4, ∠5, ∠and 8 will be 79°. The measure of angles ∠2, ∠3, ∠6, and ∠7 will be 101°.

What are supplementary angles?

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

We have been given that m angle ∠1 = 79°,

To determine the measure of each numbered angle.

As per the property supplementary angles,

m∠1  + m ∠2 = 180°
79° +  m ∠2 = 180°

m ∠2 = 180° - 79°

m ∠2 = 101°

If a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.

∠1 = ∠4 = 79°

∠2 = ∠3 = 101°

∠2 =  ∠6 = 101°

∠4 = ∠5 = 79°

∠5 = ∠8 = 79°

∠6 =  ∠7 = 101°

Thus, the measure of angles  ∠1, ∠4, ∠5, ∠and 8 will be 79°. The measure of angles ∠2, ∠3, ∠6, and ∠7 will be 101°.

find the smallest number by which 339 must be multiplied so that the product is a perfect cube. also find the cube root of the perfect cube so obtained

Answers

Answer:

The smallest number is 114921 and the cube root of the result is 339

Step-by-step explanation:

The number 339 can be factored as:

339 = 3 * 113

Both factors are prime, thus to produce a perfect cube, we must multiply by each factor to the power of 2, that is:

3^2*113^2=114921

When we multiply 339 by 114921 we get 38958219, a perfect cube which cube root is 339.

Thus, the smallest number is 114921 and the cube root of the result is 339

w=36

Step-by-step explanation:

to get the perimeter you add all sides.

w+w+2w+6+2w+6=228

6w+12=228

6w=216

w=36

length= 2(36) +6

length= 78

width= 36

If it's wrong, I apologize honestly! Answer: 91

Step-by-step explanation:

2w+6= 2(?)+6

If the perimeter is 288, then we have to find what's the closest to it. So let's try 91. 2 ×91= 182 , so it's going to be 182 +6, which equals 188. Remember if the w is 100 the w in the width is going to be 100 also, so 188 + 100= 288 glad I could help!

Answer:

The answer is £775 for hiring a car

The required answer would be the cost of hiring the car in euros is €775.

What is the Multiplication operation?

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

In August 2008, Eddie hired a car in Italy. The cost of hiring the car was £620

The exchange rate was £1 = €1.25

We have to determine the cost of hiring the car in euros (€).

According to the given question,

For the required solution, we have to multiply the exchange rate by the cost of hiring the car

The cost of hiring the car in euros (€) = 620 × exchange rate

The cost of hiring the car in euros (€) = 620 ×  €1.25

Apply the multiplication operation to get

The cost of hiring the car in euros (€) = €775

Therefore, the required answer would be the cost of hiring the car in euros is €775.
