Rafael is going for a walk. He takes 4 hours to walk 6.4 miles. What is his speed?

Answers

Answer:

Step-by-step explanation:

1.6

1.6 miles per hour is speed of Rafael.

What is Speed?

speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.

Given, Rafael is going for a walk. He takes 4 hours to walk 6.4 miles.

From the general formula of speed:

Speed = distance/time

In our case,

Distance= 6.4 miles

Time = 4 hours

Thus,

Speed = 6.4/4

Speed in miles per hour = 1.6

therefore, the speed of Rafael is 1.6 miles per hour.

x=30 is the answer to the problem

given m ll n find the value of x.

Answers

Answer:

45 degrees

Step-by-step explanation:

Since the angle x and angle 135 degrees are supplementary, you just have to minus 135 from 180 which the answer is 45 degrees.

The value of the angle x will be equal to 45 degrees.

What are lines and angles?

An endlessly long row of evenly spaced dots that spans in both directions makes up a line. Its length is the only dimension it has. A geometry called an angle is created when two line segments, lines, or rays intersect.

Given that the line is crossing the two parallel lines making an angle of 135 degrees with one line. The value of x will be calculated by using the supplementary angle property.

x + 135 = 180

x = 180 - 135

x = 45

Therefore, the value of the angle x will be equal to 45 degrees.

Column 2 is labeled temperature with entries 33, 34, 42, 36, 39, 40, 44.

What is range of data set?

The range is the difference between the highest and lowest values within a set of numbers.

Now,

For find the value of range set,

The highest value in given table = 44

The lowest value in given table = 33

Range of the data set = highest value - lowest value

Given a∥b and m∠5=77° .

What is m∠2 ?

Enter your answer in the box.

Answers

Answer:

Step-by-step explanation:

m<5 and m<4 are supplementary angles => m<5 + m< 4 = 180

m<4 = 180 -77 = 103

m<4 and m<2 are corresponding angles => m<4 = m<2 = 103

The measure of the angle m∠2 is 103.

What are supplementary angles?

The supplementary angles are defined as the angles having a sum of 180 degrees. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

In the given image the given angle is m∠5=77°. The measure of the angle m∠2 will be calculated by using some of the angle properties.

m∠5 and m∠4 are supplementary angles:-

m∠5 + m∠4 = 180

m∠4 = 180 -77 = 103

m∠4 and m∠2 are corresponding angles => m∠4 = m∠2 = 103

Therefore, the measure of the angle m∠2 is 103.

Alex, Bart, and Carl are brothers. Alex is the oldest and Carl is the youngest. The sum of the ages of the three brothers is 42. Alex's age is 3 more than twice Carl's age. The difference between Bart's and Carl's age is 7 years. Which system of equations could be used to determine the ages of all three brothers?

Answers

A = Alex

B = Bart

C = Carl

B - C = 7

A + B + C = 42

C / 2 x 3 = A

System of equations could be used to determine the ages of all three brothers are :

x + y+ z = 42

x = 3+ 2z

y -z = 7

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, let suppose the ages of all the brothers Alex, Bart, and Carl be x,y, z respectively :

x = Alex

y = Bart

z = Carl

Then according too the question the :

The equation representing the sum of the ages of the three brothers is 42 is :

x + y+ z = 42

The equation representing Alex's age is 3 more than twice Carl's age is :

x = 3+ 2z

The equation representing the difference between Bart's and Carl's age is 7 years is :

y -z = 7

Therefore, system of equations could be used to determine the ages of all three brothers are

x + y+ z = 42

x = 3+ 2z

y -z = 7
