help :( explain the meaning of -500 in context to the problem,
a plane flies directly from a city in Pennsylvania to a city in Ecuador. the equation below estimates the distance (d), In miles, from the city in Ecuador of the airplane (t) hours after taking off from the city in Pennsylvania
d=2565-500t
The equation of the distance of the plane from the city in Ecuador is a
linear equation that has a constant rate of change.
The -500 is the rate at which the distance of the plane from Ecuador changes every hour.Reasons:
The equation that estimates the distance of the plane from the city in
Ecuador is d = 2565 - 500·t
Where;
d = The distance in miles from the city in Ecuador
t = The time in hours after taking off from the city in Pennsylvania
Required:
The meaning of -500 in the context of the problem.
Solution:
By using dimensional analysis, we have;
Given that d is in miles and t is in hours, 2,565 is in miles, and 500 × t is in
miles.
Therefore, -500 is in miles per hour, which is the speed of the plane.
The -500 therefore, in the context, is the number of miles, the rate, by
which the plane becomes closer to the city in Ecuador every hour.

We can analice through a dimensional evaluation, every term in any equation.
Solution is:
The term - 500 × t
represents, the quantity of miles travel in the time t
Looking carefully each term in the equation:
d = 2565 - 500×t
And knowing:
d, is distance in milest, is time in hoursThe fact that, adding and subtracting are mathematical operations with homologous quantities. By homologous quantities we must understand that we add and subtract apples plus or (minus) apples. We never add pencils plus boxesWe are able to answer the question.
Then in the expression
d = 2565 - 500×t
As d is in miles, we must understand that 2565 is the total distance of the trip, also in miles, should and the product -500×t must also be in miles. According to that, the number 500 is necessarily in miles/hours (the speed of the plane), and the negative sign for 500 means that the total distance 2565 miles should be subtracted from the total time of travel.
For instance if t = 1 hour
d = 2565 miles - 500 (miles)/hour × 1 (hour)
As we can see we are able to determine the total time of fly, as the total distance between the cities is 2565, and 500 is the speed of the plane (constant during the whole trip).
For the whole trip
d = 2565 miles then total fly time is:
2565 (miles)/ 500 (miles/hour)×t
To get . t = 5.13 h

If a person walks 1/3 mile in 15 minutes, how far will that person walk in one hour?
Answer: 1 1/3 miles
Step-by-step explanation:
Since we know that an hour is 60 minutes, and 60 divided by 15 = 4, then we can multiply 1/3 times 4 to get the total number of miles in 60 minutes.
1/3 X 4 = 4/3
4/3 = 1 1/3
Therefore, the answer is 1 1/3 miles.
Therefore, in an hour, a person will walk 4/3 mile.

Challenge: The perimeter of a semicircular patio is 35.98 ft. What is its radius? Use 3. 14 for a.
Please Be accurate and explain
Answer:
7 ft
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr
The curved portion of a semicircle will be ...
C/2 = (2πr)/2 = πr
The straight portion of the semicircular shape will be the diameter, or 2r. That means the total perimeter of a semicircular shape is ...
P = πr +2r = r(π+2)
Then the radius is ...
r = P/(π+2) = (35.98 ft)/(3.14+2) = 7 ft
The radius of the patio is 7 ft.

2. Use the conversion table to convert the following metric units into the given English units.
Round your answers to two decimal places.
a. 12 mm to inches
b. 75 km to miles
C. 150 m to feet
d. 63 square meters to square feet
e 45 meters per second to feet per second
1.9 L (liters) to U.S.quarts
Answer:
I need only 5 brainlisted please give meStep-by-step explanation:
please anyone please I request you allThe conversion is a. 12 mm ≈ 0.47 inches
b. 75 km ≈ 46.60 miles
c. 150 m ≈ 492.13 feet
d. 63 square meters ≈ 678.13 square feet
e. 45 meters per second ≈ 147.64 feet per second
f. 1.9 L ≈ 2.01 U.S. quarts
To convert the metric units into the given English units, we'll use the following conversion factors:
1 inch = 25.4 mm
1 mile = 1.60934 km
1 meter = 3.28084 feet
1 square meter = 10.7639 square feet
1 meter per second = 3.28084 feet per second
1 liter = 1.05669 U.S. quarts
a. 12 mm to inches:
12 mm * (1 inch / 25.4 mm) ≈ 0.47 inches
b. 75 km to miles:
75 km * (1 mile / 1.60934 km) ≈ 46.60 miles
c. 150 m to feet:
150 m * (3.28084 feet / 1 meter) ≈ 492.13 feet
d. 63 square meters to square feet:
63 square meters * (10.7639 square feet / 1 square meter) ≈ 678.13 square feet
e. 45 meters per second to feet per second:
45 meters per second * (3.28084 feet per second / 1 meter per second) ≈ 147.64 feet per second
f. 1.9 L (liters) to U.S. quarts:
1.9 L * (1.05669 U.S. quarts / 1 liter) ≈ 2.01 U.S. quarts
So, after rounding to two decimal places:
a. 12 mm ≈ 0.47 inches
b. 75 km ≈ 46.60 miles
c. 150 m ≈ 492.13 feet
d. 63 square meters ≈ 678.13 square feet
e. 45 meters per second ≈ 147.64 feet per second
f. 1.9 L ≈ 2.01 U.S. quarts

Martin, his 2 brothers, and his 5 sisters want to fairly share 3 bottles of water. How
much water will Martin get?
Answer:
3/8 bottle
Step-by-step explanation:
Fractions are just division.
Martin + 2sisters + 5bros
= 8 people
3bottles ÷ 8people
= 3/8 bottles per person
Martin is a person, so he gets 3/8 of a bottle, if they all share equally.
Using proportions, it is found that Martin will get 0.375 of a bottle.
This question is solved by proportions, using a rule of three.Martin, his 2 brothers and 5 sisters combine to represent 8 people, which will share 3 bottles equally. How much will Martin, which is one person, get?The rule of three is:
1 person - x bottles
8 people - 3 bottles
Applying cross multiplication:
[tex]8x = 3[/tex]
[tex]x = \frac{3}{8}[/tex]
[tex]x = 0.375[/tex]
Martin will get 0.375 of a bottle.

sonya has 12 cup box of ceral she wants to pour the cereal into small 1/4 cup snake how many bags of cereal will she have
a- 48
b-36
c- 24
d- 12/48
e-3
Answer:
a - 48
Step-by-step explanation:
12 cups are divided into 1/4 cup bags.
Converting 12 into a fraction, you get:
12/1 divided by 1/4.
When we divide fractions, we flip the second fraction and change the operation to multiplication.
12/1 * 4/1.
Since 12/1 and 4/1 are now just whole numbers, (12 and 4), we can multiply them together.
12 * 4 = 48.
