Answer:

5 Laps

Step-by-step explanation:

The question says that she runs the same distance everyday. This shows us that...

2 laps on a running trail and 6 more miles = 4 laps on a running trail and 2 more miles

We can turn laps into the variable L and miles into the variable M to create an equation

2 L + 6 M = 4 L + 2 M

We can start by subtracting 2 M from both sides to get:

2 L + 4 M = 4 L

Now, we can subtract 2 L from both sides

4 M = 2 L

This tells us that 2 laps are 4 miles which means that 1 lap is 2 miles.

Now, we can break down either side of the equation. Let's break down

2 L + 6 M

First, we can turn the miles into laps. We know that 2 miles is one lap so we can divide 6 by 2. Our Equation:

2 L + 3 L

Now, we can simplify this :

5 L

Now we know that she ran 5 laps on saturday.

Hope this Helps!!! :)

Let me know in the comments if this answer was perfect or if I should change anything!!!

Write an equation (a) in slope intercept form and (b) in standard form for the line passing through (-2,6) and perpendicular to
Rudik [331]

Answer:

a) y = 3x+12

b) y-6 = 3(x+2)

Step-by-step explanation:

The equation of a line in slope-intercept form is expressed as y = mx+c

m is the slope or gradient

c is the intercept

We need to calculate the value of slope and intercept.

We will get the slope from the equation of line x+3y = 7

Rewriting the equation

3y = 7-x

y = 7/3 -x/3

M = -1/3

Since the equation if the unknown line is perpendicular to this line then Mm = -1 where m is the slope of the unknown line

m = -1/M

m = -1/(-1/3)

m = 3

To get c, we will substite the point given (-2,6) and the slope into the equation y = mx+c

6 = 3(-2)+c

6 = -6+c

c = 12

Substituting m= 3 and c = 12 into the standard form of the equation we have;

y = 3x+12 (This gives the required equation in its slope intercept form)

b) The standard form of a line is expressed as y-y1 = m(x-x1) where (x1,y1) are the points and m is the slope. On substituting the point {-2,6) and slope of 3 into this equation we will have:

y - 6 = 3(x-(-2))

y-6 = 3(x+2)

This gives the equation of the line in its standard form

What is the approximate area of the circle that fits perfectly inside of the square? Use Pi = 3.14 and round to the nearest tent
Pani-rosa [81]

Answer:

19.625\text{ cm}^2

Step-by-step explanation:

GIVEN: A square with base 5\text{ cm}, a circle that perfectly fits inside square.

TO FIND: Approximate area of circle.

SOLUTION:

Consider the figure attached.

let the radius of circle be x\text{ cm}

radius of circle =\frac{\text{length of base of square}}{2}

                     x=\frac{5}{2}\text{ cm}

                     x=2.5\text{ cm}

Area of circle =\pi(radius)^2

                      =3.14\times(2.5)^2

                      =19.625\text{ cm}^2

Hence the area of circle that perfectly fits inside the square is 19.625\text{ cm}^2

At every company meeting, the president speaks for 20 minutes and then takes questions from her employees. Let q represent the n
ololo11 [35]

Answer:

t = 20 + q (minutes)

Step-by-step explanation:

The meeting consists of speaking and Question & Answer (Q&A) sessions.

Speaking session = 20 minutes

Q&A session = q minutes

Total number of minutes spent for the two sessions = 20 + q (minutes)

But total number of minutes meeting lasted = t minutes.

Therefore, t = 20 + q (because they both represent the total number of minutes the meeting lasted)
