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.

Find the greatest common factor of 14 and 55
Answer: The factors of 14 are 14, 7, 2, 1.
The factors of 55 are 55, 11, 5, 1.
The common factors of 14 and 55 are 1, intersecting the two sets above.
In the intersection factors of 14 factors of 55 the greatest element is 1.
Therefore, the greatest common factor of 14 and 55 is 1.
Step-by-step explanation:
The greatest common factor of 14 and 55 is 1.
To find the greatest common factor of 14 and 55.
First write the factor of 14.
14 × 1 = 14, 7 × 2 = 14, 2 × 7 = 14, 1 × 14 = 14.
Which are 14, 7, 2 and 1.
Now, write the factor of 55.
55 × 1 = 55, 11 × 5 = 55, 5 × 11 = 55, 1 × 55 = 55
Which are 55, 11, 5 and 1
Therefore, the common factor of 14 and 55 is 1.

A family eats out at a restaurant and the total for their meals is $73.89. They also pay sales tax of 5.8% and leave a tip for their server. If the family leaves a total of $93, which of the following might be a description of the service they received? a. They left a 10% tip, so the service was probably below average. b. They left a 15% tip, so the service was probably average. c. They left a 20% tip, so the service was probably above average. d. They left a 25% tip, so the service was probably outstanding.
Answer:
C.
Step-by-step explanation:
The sales tax is ≈ 12.74
The total of $93 - (12.74 + 73.89) = 6.37
$6.37 is approximatley 20%
The description of the service they received is
They left a 20% tip, so the service was probably above average.
What is percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
let the amount of tax be x.
So, 100% of x = 73.89 x 5.8%
x = 428.562/100
x= 4.285
Now, the tip amount would be
= 93 - 73.89 4.28
= $14.83
Now, the amount of tip in percent is
73.89 / 100 = 14.83 / x
x = 14.83 /0.7389
x= 20.07
x= 20%

Sarah would like to hire a clown for her daughter's birthday party. Clown A
is offering his services for an initial fee of $105 in addition to $9 per hour.
Clown B is offering her services for an initial $155 fee in addition to $6 per
hour. When will the two clowns charge the same amount of money? Use a
table to estimate the solution.
The two clowns charge the same amount of money at 16.66 hours.
What is Wages?Payment for work based on hours worked (or sometimes per day or per amount of work done).
Here, let the duration of birthday party be x hours.
For Clown A,
Initial fee = $ 105
Additional charge = $ 9 per hour
Total amount of clown A = $ (9x + 105) ...........(i)
For Clown B,
Initial fee = $ 155
Additional charge = $ 6 per hour
Total amount of clown B = $ (6x + 155) ...........(i)
Now, according to question
9x + 105 = 6x + 155
9x - 6x = 155 - 105
3x = 50
x = 50/3
x = 16.66 hours
Thus, the two clowns charge the same amount of money at 16.66 hours.

Rosa is looking at a map of the park that is laid out on a coordinate plane. Rosa is at(1, -1). The shelter house is at (-2, -4) and the fossil exhibit is at (3, 2). Each unit on the map represents 100 feet. How much closer is rosa to the fossil exhibit than to the shelter house
Answer:
[tex]63.709feet[/tex]
Step-by-step explanation:
This deals with the distance between two pointsuse the equation [tex]distance=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}[/tex] So we do the follow stepsFind distance from Rosa to Shelter houseFind distance from Rosa to Fossil exhibitSubtract the two answers to see differenceSo distance from Rosa to Shelter, we use (1,-1) and (-2,-4) so you plug your points in as follows [tex](1,-1)=(x_1,y_1)[/tex] and [tex](-2,-4)=(x_2,y_2)[/tex] so then[tex]distance=\sqrt{((-2)-(1))^{2}+((-4)-(-1))^{2}}\\ distance=\sqrt{(-3)^{2}+(-3)^{2}}\\ distance=\sqrt{9+9}\\ distance=\sqrt{18}=4.24264[/tex] approximately (round off as they require)Now putting that into feet [tex]4.24264*100feet=424.264feet[/tex] Then next, distance from Rosa to Fossil exhibit, we use (1,-1) and (3,2) so you plug your points in as follows[tex]distance=\sqrt{((3)-(1))^{2}+((2)-(-1))^{2}}\\ distance=\sqrt{(2)^{2}+(3)^{2}}\\ distance=\sqrt{4+9}\\ distance=\sqrt{13}=3.60555[/tex] approximately (round off as they require)Now putting that into feet [tex]3.60555*100feet=360.555feet[/tex] So right away we know, Rosa is closer to the Fossil exhibit than the ShelterThen to know by how much we subtract the longer distance from the shorter so [tex]424.264feet-360.555feet=63.709feet[/tex]Rosa is closer to fossil exhibit than shelter house.
What is Distance Formula?The two points in the cartesian plane P(a, b) and Q(c, d) then the distance between P and Q is
PQ = √c-a )² + (d-b)²
The distance from Rosa to shelter house
d= √(-2-1)² + (-4 +1)²
d =√9 + 9
d = √18

Given: AE= 7 5/8cm, AB=BC, CD= 1/2cm, and DE is 3/8 more than AB. What is the length of DE?
Answer:
Length of DE = 2.90 (Approx)
Step-by-step explanation:
Given:
AE = 7[tex]\frac{5}{8}[/tex]cm = 61 / 8 cm = 7.625 cm
AB = BC
CD = 1/2 cm = 0.5 cm
DE is 3/8 more than AB
Find:
Length of DE
Computation:
Assume;
AB = BC = x
So,
DE = x + 3/8(x) = [11 / 8]x = [1.375]x cm
AE = AB + BC + CD + DE
7.625 = x + x + 0.5 + [1.375]x
7.125 = 3.375 x
x = 2.1111 (Approx)
Length of DE = [1.375][2.111]
Length of DE = 2.90 (Approx)
