Effie and Kristen live 23.6 km apart. They decided to cycle to the pool at the park, which is located between their homes. If Jennifer lives 5.2 km closer to the park, how far did they each cycle?

It take the speed of 299 m to travel 30 cm .

What is speed?

Speed is what it means. the speed at which an object's position changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed only has a direction and no magnitude, it is a scalar quantity.

Let us convert cm to m for distances

C = 2.998× 10^8 ms

The relationship between distance, speed, and time is

T =1 ×10^6/8

Because in this case you are being asked how long or time it takes, make it the subject.

Rounding the quotient produces.

Adjust it again to fit the scientific notation.

The result is -

d= c×t

d=2.998×10^8 m/s 10^6 m/s

d=2.998

As a mathematical expression, the time taken for light is 2.998

Answer:

through: (-4, 1) and (1, -3) how do u write the point slope form of the equation of the line through the given points ?

Step-by-step explanation:

to find slope you do delta y over delta x meaning 3 - 1 over 1 - (-4) you get 2/5 that is slope then you do to find b you take one of the points and you plug in for y = mx + b doesn't matter which one so -3 = 2/5 (1) + b

-3 = 2/5 + b

subtract 2/5 from both sides you get

-17/5 = b

so the equation is

y = 2/5x - 17/5

The total area of the shaded regions is 72 unit sq.

The area of a square can be calculated as the square of the sides of a given figure.

The area of a square = side x side

Given that square has an area of 196.

The region contains two overlapping squares that is the larger of these squares has an area 4 times that of the smaller and the area of their overlap is 1.

We can come up with equations as;

Since the area of their overlap is 1 then the side length is 1 unit.

Let the length of the smaller square is x.

The length of the larger square is 2x.

Therefore,

x + 2x - 1 = 3x - 1

Thus, 3x - 1 = 14

x = 5

The area of larger square = 100

Sandeep picked up 4.5 pounds of fresh apples from the field

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the standard form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant.

Pounds of pre-picked apples picked up by Sandeep = 3 pounds

Charges per pound = $4

The total amount paid by Sandeep = $30

Let x be the pounds of fresh apples picked up by Sandeep

In the formulation of the equation we get the following:

Pounds of pre-picked apples*Charges per pound + Pounds of fresh apple picked*Charges per pound = Total amount paid by Sandeep

= 3*4 + x*4 = 30

12 +4x = 30

4x = 18

x = 4.5

Collect like terms

Y= 2x+3

We have that the data is: (x₁ = 2, y₁ = 2) and (x₂ = 6, y₂ = 3).

The equation for straight line can be used to plot it on the graph. The amount of discount is 4.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

The given equation is as follows,

5x + (–2y) = 8

Here, x is the number of picture frames purchased after discount.

And, y is the total amount spent.

In order to find the discount, write the equation in terms of y as,

5x + (–2y) = 8

=> 2y = 5x - 8

=> y = 5 / 2 x - 4

The above equation can be plotted as a graph which is shown below,

It is found from the graph that slope is 5 / 2 which is the rate of per picture.

Since the frames are being purchased after the discount, from the above graph  discount can be obtained as 4.

Hence, the discount on the picture frames is given by 4.

The probability P (a number less than 2 on the blue cube and odd number on the green cube) is 1/12.

What is probability?

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

For the probability,

The sample space of a die is, S = {1,2,3,4,5,6}

The probability of getting a number less than 2 is P(x < 2) = 1/6

The probability of getting an odd number is P(Odd) = 3/6

The required probability is calculated as:

P = 1/6 * 3/6

P = 1/12

Applying the triangle sum theorem and the angle-side relationship, the longest side of triangle ABC is: side AC.

The triangle sum theorem states that if we add all three interior angles of a triangle, the sum we get would be equal to 180 degrees.

The angle-side relationship of a triangle explains that the longest side of a triangle is always opposite to its largest angle, the medium side is opposite to the medium angle, and the shortest side is to the smallest angle of the triangle.

Given that triangle ABC has the following angle measures:

m∠A = 60°

m∠B = (3x - 2)°

m∠C = (2x + 7)°

Therefore:

m∠A + m∠B + m∠C = 180

Substitute:

60° + (3x - 2)° + (2x + 7)° = 180

60 + 3x - 2 + 2x + 7 = 180

Combine like terms:

65 + 5x = 180

5x = 180 - 65

5x = 115

x = 23

Find the measure of each of the angles by plugging in the value of x:

m∠B = (3x - 2)° = 3(23) - 2 = 67°

m∠C = (2x + 7)° = 2(23) + 7 = 53°

The largest angle is m∠B = 67°.

AC is opposite to angle B, therefore, AC is the longest side of the triangle.
