A circular running track is
1/8
mile long. Elena runs on this track, completing each lap in
1/24
of an hour.
What is Elena's running speed, in miles per hour? Type just the number answer..
Answers
Answer:
3 miles per hour
Step-by-step explanation:
Speed is defined as the distance covered per unit time, which can be expressed mathematically as follows;
Speed = Distance/Time
The given parameters are;
The length of the circular running track = 1/8 mile
The time it takes Elena to complete a lap = 1/24 hour
Therefore, we have;
Elena's running speed = The distance Elena completes/(The time it takes Elena to complete the given distance)
∴ Elena's running speed = The 1/8 mile track/(1/24 hour)
[tex]Elena's \ running \ speed =\dfrac{\dfrac{1}{8} \ mile }{\dfrac{1}{24} \ hour } = \left (\dfrac{1 }{8} \times \dfrac{24}{1 } \right ) \ \dfrac{mile}{hour} = \dfrac{24}{8} \ \dfrac{mile}{hour} =3 \ mile/hour[/tex]
Elena's running speed = 3 mile per hour.

Sam opens a savings account with $800. He saves $50 per month. Assume that he does not withdraw money or make any additional deposits.
Answers
Answer:
wheres the end of the question
Step-by-step explanation:
Sam opens a savings account with $800. He saves $50 per month. Assume that he does not withdraw money or make any additional deposits.
Write a linear model (equation) that represents the total amount of money Sam deposits into his account after m months.
Equation:
b. After how many months will Sam have more than $3500? Show your work.
c. Use the equation and create a table to represent the situation.
Solution:
Savings = 800 + 50m
$800 is the initial savings and $50 are saved every month. By adding these two, we will get the total savings.
B) Use 3500 in the above equation
3500 = 800 + 5m
Taking 800 to other side
5m = 3500 - 800
5m = 2700
m = 2700/5 = 540
It will take him 540 months to save $3500. So we can say that it will take him 541 months to make more than $3500.
C) Make a table with two columns: Months and Total Savings
Take random values of m, put those values in the equation to get total savings for that month.

The least 3 digit number divisible by 30 is 120 and the greatest is 990.
Answer: 30
Step-by-step explanation:
Divisible by 2,3 and 5 means divisible by 2*3*5=30
So we require to calculate number of multiples of 30 in the range 100 to 999.
The least 3 digit number divisible by 30 is 120 and greatest is 990.
This is an AP series with common difference 30.
First number is 120 and n'th number is 990.
We need to find n.
Using the AP series formula
120 + (n-1)*30= 990
or n= 30
There are 30 3-digit numbers divisible by 2,3 and 5.

What is the area of an EQUALATERAL triangle with a side length of 6? I'm getting 5.19615242, is this right?
Answers
Answer:
15.59.
Step-by-step explanation:
The altitude of equilateral triangle bisects the base
So 1/2 base = 3.
Altitude of the triangle is found from Pythagoras theorem:
= sqrt(6^2 - 3^2)
= sqrt27
Area = 1/2 base * altitude
= 3 * sqrt27
= 15.59

Emir flew home from vacation with a heavy bag. With the first airline he flew, Emir had to pay $20 to check his bag, plus $10 for every pound that his bag was over the weight limit. The next flight was with another airline that had the same weight limit. Emir had to pay $5 per pound that his bag was over the weight limit, in addition to the checked bag fee of $30. By coincidence, the fees ended up being the same with both airlines. How large was each airline's fee?
Answers
Answer:
$27.5
Step-by-step explanation:
Let
x = pound over weight limit
Airline 1 = 20 + 10x
Airline 2 = 5 + 30x
Equate the fees
20 + 10x = 5 + 30x
20 - 5 = 30x - 10x
15 = 20x
x = 15/20
x = 0.75 pounds
How large was each airline's fee?
Airline 1 = 20 + 10x
= 20 + 10(0.75)
= 20 + 7.5
= $27.5
Airline 2 = 5 + 30x
= 5 + 30(0.75)
= 5 + 22.5
= $27.5

a farmer has enough food to feed 50 animals in his cattle for 15 days . how long will the food last if there are 25 more animals in his cattle?
Answers
Answer:
The food will last for 10 days
Step-by-step explanation:
Proportions
The amount of food the farmer needs to feed his animals is proportional to the number of animals and to the number of days they are fed.
This can be written as:
Food=k*N*D
Where k is a constant, N is the number of animals and D is the number of days.
We know that the farmer has enough food to feed N=50 animals for D=15 days, thus:
Food=k*50*15=750k
If the same amount of food is used for 50+25=75 animals, then:
750k=k*75*D
Simplifying:
750=75*D
Dividing by 75:
D=10
The food will last for 10 days

GEOMETRY Identify the segment bisector of (FG) . Then find (FG)
Answers
Answer:
The segment bisector of FG is HI because it splits it into two equal parts. Since point F to the bisector equals 33 and the bisector to point G is the same, that would also be 33. 33+33=66=FG
Step-by-step explanation:
The measurement of the line segment FG is 66 units.
We need to identify the segment bisector of FG and then find FG.
What is the bisector of the line segment?A segment bisector is a line, a ray, a line segment, or a point that cuts a line segment at the centre dividing the line into two equal parts. The word segment can also be referred to as line segment which means a segment is a part of the line that has fixed endpoints. The word bisect means cutting any object or line into two equal halves. Hence, a segment bisector is referred to as when two line segments bisect or cut each other at a point dividing the lines into equal halves.
From the given figure, HI is the bisector of the line segment FG.
Given that, 1/2 (FG)=33 units
⇒FG=66 units
Therefore, the measurement of the line segment FG is 66 units.
