Training field is formed by joining a rectangle and 2 semicircles rectangle is 93 m long and 61 m wide what is the length of a training track running around the field use pi and don't round answer
Complete Question
The diagram for this question is shown on the first uploaded image
Answer:
The length of a training track running around the field is [tex]Z = 377.54 \ m[/tex]
Step-by-step explanation:
From the question we are told that
The length of the field is [tex]L= 93 \ m[/tex]
The width of the field is [tex]W = 61 \ m[/tex]
The length of the two semicircle is mathematically evaluated as
[tex]A = 2 * \pi * \frac{W}{2}[/tex]
substituting values
[tex]A = 2 *3.142 * \frac{61}{2}[/tex]
[tex]A = 191.54 \ m[/tex]
Now the length of a training track running around the field is
[tex]Z = A + 2 L[/tex]
substituting values
[tex]Z = 191.54 + 2 (93)[/tex]
[tex]Z = 377.54 \ m[/tex]
Prosta aa i prosta bb są do siebie prostopadłe, a także prosta bb i prosta cc są do siebie prostopadłe. Wybierz poprawne uzupełnienie zdania. Prosta aa jest prostopadła / równoległa do prostej cc.
Answer:
- In a 3-D setting, straight line aa can be perpendicular or parallel to straight line cc.
- In a 2-D setting, straight line aa can only be parallel to straight line cc.
- W ustawieniu trójwymiarowym linia prosta aa może być prostopadła lub równoległa do linii prostej cc.
- W ustawieniu 2-D linia prosta aa może być równoległa do linii prostej cc.
Step-by-step explanation:
English Translation
Straight line aa and straight line bb are perpendicular to each other, as well as straight line bb and straight line cc are perpendicular to each other. Choose the correct completion of the sentence. Line aa is perpendicular / parallel to line cc.
Solution
If the frame of reference for the lines is in 3-D, then, it is the straight line aa can also be perpendicular to the straight line cc in the same vein as the x, y and z component lines are usually all perpendicular to one another. Note that straight line aa could also be parallel to straight line cc in a 3-D frame of reference.
But in a 2-D frame of reference, straight line aa can only be parallel to straight line cc. This is because the only directions that straight line bb can be perpendicular to, in a 2-D setting, are all in the same parallel direction.
In Polish/Po polsku
Jeśli układ odniesienia dla linii jest w 3-D, to jest to linia prosta aa może być również prostopadła do linii prostej cc w tej samej żyle, ponieważ linie składowe x, y i z są zwykle wszystkie prostopadłe do jednego inne. Należy zauważyć, że linia prosta aa może być również równoległa do linii prostej cc w trójwymiarowym układzie odniesienia.
Ale w dwuwymiarowym układzie odniesienia linia prosta aa może być tylko równoległa do linii prostej cc. Jest tak, ponieważ jedyne kierunki, w których prosta bb może być prostopadła, w ustawieniu 2-D, wszystkie są w tym samym kierunku równoległym.

Nar donated to 4 charities last year. She gave £175 to each of these charities. This year Rana wants to donate the same total amount between 6 charities. Each charity will receive an equal amount How much will each charity receive this year?
Answer:
£116.67
Step-by-step explanation:
Given;
Nar donated to 4 charities last year. She gave £175 to each of these charities.
The total amount Nar donated is;
Nar = 4 × £175 = £700
For Rana to donate the same amount equally among 6 charity, to determine the amount each charity would receive this year, we need to divide the total amount by the number of charities;
A = £700/6
A = £116.67
Grace has $81 in her bank account and deposits $68 per month into her account. Jasmine has $53 and deposits $75 per month into her account. Enter the number of months it will take for both Grace and Jasmine to have the same amount of money in their accounts.
Answer:
4 months
Step-by-step explanation:
Let the number of months that they deposit into their accounts be m.
Grace has $81 in her bank account and deposits $68 per month into her account. This means that after m months, she will have:
81 + 68m
Jasmine has $53 and deposits $75 per month into her account. This means that after m months, she will have:
53 + 75m
To find the number of months it will take for them to have the same amount, we equate the amount that they each have:
81 + 68m = 53 + 75m
Collect like terms and simplify:
81 - 53 = 75m - 68m
28 = 7m
=> m = 28 / 7 = 4
It will take 4 months for them to have the same amount.
Card 1 has a current balance of $8,312.69 with an APR of 24.16%, and the credit limit on the card is $10,000.
Card 2 has a current balance of $1,180.34 with an APR of 21.15%, and the credit limit on the card is $7,500.
In your own words, tell which credit card you should focus on paying off first and why?
Be sure to include the credit card AND the reason for paying that card off first.
Answer:
The focus should be on paying off Card 1 first
Step-by-step explanation:
The credit limit for card 1 is $10,000,invariably the cardholder only $ 1,687.31
($10,000-$8,312.69) to reach its limit,hence available balance to draw from and also the annual percentage rate is higher for card card 1.
For every balance in card 1, the cardholder pays 24.16% APR annually compared to 21.15% applicable to card,as a result,card is cheaper.
Besides,the cardholder still has an available credit of $ 6,319.66
($7,500-$1,180.34) on card 2 which comes at a lower APR

The list below shows the number of push-ups students could complete in 1 minute. 14, 19, 20, 12, 14 Find the mean and median number of push-ups completed. Please write the answer in this format: mean= ___ median= ____
Answer:
Mean= 15.8, Median= 14.
Step-by-step explanation:
To find the mean, we need to find the average. We will simply need to add up all of the values and divide by how many there are.
Therefore:
[tex]\frac{14 + 19 + 20 + 12 + 14}{5}[/tex]= 15.8 = Mean.
To find the median, you can arrange the numbers in increasing order and find the middle value. You can do this like so:
12, 14, 14, 19, 20
The number in the middle of 14.

A circular table top has a radius of 60cm. A force of 650N is applied to the whole table top. Calculate the pressure in N/m to 4sf
Answer:
i hope its understood....
Brainliest question please help please help me now plz
Answer:
Option A) Inside the circle
Step-by-step explanation:
step 1
Find the radius of the circle
we know that
The radius is equal to the distance from the center to any point on the circle
the formula to calculate the distance between two points is equal to
[tex]d\sqrt{(y2-y1)^2+(x2-x1)^2 }[/tex]
we have
A(-5,-8),M(-1,-3)
substitute the values
[tex]r=\sqrt{(-3+8)^{2}+(-1+5)^{2}}[/tex]
[tex]r=\sqrt{(5)^{2}+(4)^{2}}[/tex]
[tex]r=\sqrt{41}\ units[/tex]
step 2
Find the distance from the center to point V
we know that
If the distance from the center to point V is equal to the radius, then the point V lie on the circle
If the distance from the center to point V is less than the radius, then the point V lie inside the circle
If the distance from the center to point V is greater than the radius, then the point V lie outside the circle
we have
A(-5,-8),V(-11,-6)
substitute in the formula
[tex]d=\sqrt{(-6+8)^{2}+(-11+5)^{2}}[/tex]
[tex]d=\sqrt{(2)^{2}+(-6)^{2}}[/tex]
[tex]d=\sqrt{40}\ units[/tex]
so
[tex]\sqrt{40}\ units< \sqrt{41}\ units[/tex]
The distance from the center to point V is less than the radius
therefore
The point V lie inside the circle

Dreg earns $6.80 per hour. On Saturday he worked from 9:00 A.M.
to 3:30 P.M. How much did he earn?
Answer:
$44.20
Step-by-step explanation:
First, calculate how many hours he worked. From 9:00am-3:30pm he worked 6.5 hours. We're going to multiply the hourly rate, $6.80 by how many hours he worked. Since he also worked an extra half hour and not a full hour we're going to divide $6.80 by 2. Then add both of the calculations up to get the asnwer.
6.8(6)=40.8
6.80/2=3.4
40.8+3.4=44.2
He earned $44.20.

Neglecting air resistance, the distance h(t) in feet traveled by a freely falling object is given by the function , where t is time in seconds. The height of a certain tower is 912 feet. How long would it take an object to fall to the ground from the top of the building? Round to nearest 0.1 second
Answer:
t = 7.54 seconds
Step-by-step explanation:
The distance h(t) in feet traveled by a freely falling object is given by the function :
[tex]h(t)=16t^2[/tex]
The height of a tower is 912 feet.
It is required to find the time it will taken to fall on ground from the top of the building. It can be calculated as :
[tex]16t^2=912\\\\t=\sqrt{\dfrac{912}{16}}\\\\t=7.54\ s[/tex]
So it will taken 7.54 seconds to fall on the ground.
Ali made $126 for 9 hours of work. At the same rate, how many hours would he have to work to make $168 ?
Answer:
12 hours
Step-by-step explanation:
First to solve this problem, let's look at what we are dealing with here. It says that Ali made $126 for 9 hours of work.
Let's set that up into a fraction so it's easier to look at.
money/time = 126/9
Now that we have that set up let's look at our other piece of information.
It asks for how many hours would Ali have to work in order to make $168 so let's figure that out.
In order to find out the number of hours, let's first find our unit rate which can be simply found by dividing our given money/time.
126/9 = 14.
This means that for every 1 hour, there will be 14 dollars earned.
Now that we know that, let's look for how many hours it take to earn $168.
In order to do that simply see how many times 14 goes into 168 (division) and that way you can see how many hours it will take to earn $168.
168/14 = 12 hours.

Helen gathered 37 mushrooms in three hours. How many mushrooms did she gather every hour, if she gathered 7 more mushrooms in the second hour than in the first hour, and 6 more in the third hour than in the first hour?
Helen gathered
mushrooms in the first hour,
mushrooms in the second hour and
mushrooms in the third hour.
Answer:
On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.
Step-by-step explanation:
Helen gathred a total of 37 mushroons in three hours. On the first hour she gathered "x" mushroons, on the second hour she gathered "x + 7" mushroons and on the third hour she gathered "x + 6". Therefore the sum of mushrrons she gathered on each hour should be equal to the total she gathered as shown below:
37 = x + (x+ 7) + (x + 6)
37 = 3*x + 13
3*x + 13 = 37
3*x = 37 - 13
3*x = 24
x = 24 / 3
x = 8
On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.
