A falcon flies 800,000 meters in 4 hours. Use the formula d = rt, where d represents distance, r represents rate, and t represents time, to answer the following questions. Show your work.
Part A: Rearrange the distance formula, d = rt, to solve for rate. (2 points)
Part B: Find the falcon's rate in meters per hour. (3 points)
Part C: Find the falcon's rate in kilometers per hour. (3 points)
Part D: Which unit, meters, or kilometers, makes more sense to use in this scenario, and why? (2 points)
Answers
The answers are :
Part A: r = d/t, Part B: 200,000 meters per hour, Part C: 200 kilometres per hour Part D: Kilometres is more appropriate.
Part A: To rearrange the distance formula for the value of rate, rate will be on Left Hand Side of the equation and other variables will be on Right Hand Side of the equation.
rate = distance/time.
Part B: Rate in meter per hour can be calculated by keeping the values in formula formed in Part A.
Rate = 800,000 ÷ 4
Rate = 200,000 meters per hour.
Part C: To find the rate in kilometres per hour, we will simply convert the calculated rate from meters to kilometres. As per the known fact, 1000 meters = 1 kilometre.
Rate = 200,000 ÷ 1000
Rate = 200 kilometres per hour
Part D: The use of unit kilometre is more appropriate in this problem. This is because the speed is fast and contains many zeroes. Reading and understanding in the form of kilometres is more practical in comparison to meters.
Hence, Part A: r = d/t, Part B: 200,000 meters per hour, Part C: 200 kilometres per hour Part D: Kilometres is more appropriate

Answers
Answer:
c) 5
Step-by-step explanation:
Solving for the value of x,
→ 3x - 8 - 4x = -13
→ 3x - 4x = -13 + 8
→ -x = -5
→ [ x = 5 ]
Thus, the value of x is 5.
Answer:
5
Step-by-step explanation:
Use PEMDAS
First you should do is to combine like terms
[tex] - x - 8 = - 13[/tex]
Haveing combined ike terms you need to add 8 to both sides (Like terms are terms that have the same variable like,x)
[tex] - x = - 5[/tex]
Then divide by a negative 1

Answer:
60 percent
I think it is 60 but you might need a more certifyd answer
==================================================
Explanation:
A is 40% of B
This translates to the equation A = 0.40B or A = 0.4B
This is because 40% converts to 0.40 in decimal form
Let's divide both sides by 0.4 to isolate B
A = 0.4B
A/0.4 = B
B = (1/0.4)A
B = 2.5A
This shows that B is 250% of A
------------
Another approach:
40% = 40/100 = 2/5
"A is 40% of B" is the same as "A is 2/5 of B
So,
A = (2/5)*B
5A = 2B
2B = 5A
B = 5A/2
B = (5/2)A
B = 2.5A
which is another way to show that B is 250% of A

Tom and ben both get paid the same amount for every hour they work. tom worked 5 hours and ben worked 6 hours. together, they received r1 430. how much money did each receive?
Answers
Tom and Ben received 650 and 780 respectively.
Let the amount paid to each for every hour they work be x. Now, forming the equation as per the given information in question.
5x + 6x = 1430
Performing addition to find the value of x.
11x = 1430
Shifting 11 to Right Hand Side of the equation
x = 1430 ÷ 11
Performing division to find the value of x
x = 130
Now finding the amount received by Tom and Ben based on the number of hours they worked.
Amount received by Tom = 5x
Amount received by Tom = 5 × 130
Amount received by Tom = 650
Amount received by Ben = 6x
Amount received by Ben = 6 × 130
Amount received by Ben = 780
Therefore, the amount received by Tom and Ben are 650 and 780 respectively.

What is the product of −2 1/4 and 2 1/2?
help me
Answers
The problem is asking for the product, meaning we need to multiply.
-2 1/4 * 2 1/2
To make multiplying easier, we can convert the mixed numbers into improper fractions.
2 * 4 = 8, + 1 = 9/4
2 * 2 = 4, + 1 = 5/2
Now, we have this:
-9/4 * 5/2
Since the denominators are different, we can find the least common multiple of the denominators to make them the same. In this case, the least common multiple of 4 and 2 is 4.
-9/4 * 1 = -9/4
5/2 * 2 = 10/4
Now, we have this:
-9/4 * 10/4
We can now multiply!
-9 * 10 = -90
/4 * /4 = /16
= -90/16
You can simply the improper fraction if you'd like.
-90 / 16 = -5.625
So, our answer is -90/16, or -5.625.

The lengths of the three sides of a triangle (in centimeters) are consecutive odd
integers. If the perimeter is 45 centimeters, find the value of the shortest of the three
side lengths.
Answers
Answer:
13, 15,17
Step-by-step explanation:
Let x = the first number
Let x + 2 = the second number
Let x + 4 = the third number
Consecutive means in order like 1,2,3 or 20,21,22. Consecutive odd means that you want three numbers in order that are odd. Each number would be 2 more than the number before. For example 5 + 2 = 7. We would have to add 4 to 5 to find the next consecutive odd number.
x + (x + 2) + (x +4) = 45 I put the numbers in parentheses so you could see the first number plus the second number plus the third number equals 45
x + x+ 2 + x+ 4 = 45 Combine like terms
3x + 6 = 45 Subtract 6 from both sides of the equation.
3x = 39 Divide both sides by 3
x = 13
Add 2 to that to get the next odd number.
Add 4 to 13 to get the third odd number.
Answer: 13 cm
Step-by-step explanation:
Let the value of the shortest of the three side lengths is x.
Since the three sides of a triangle are consecutive odd
integers, hence: x, x+2, x+4.
Thus,
[tex]P=x+(x+2)+(x+4)\\45=x+x+2+x+4\\45=3x+6\\45-6=3x+6-6\\39=3x\\[/tex]

Answers
The numbers ordered from least to greatest are- 2.14, 2.2, 2.221, 2.276, 2.26, 2.291.
Here, we are given 6 numbers-
2.2, 2.276, 2.291, 2.14, 2.26, 2.221
Now, we can add as many zeroes as we want after the decimal, it does not change the value of the number.
Thus, let us make all the numbers 3 digit decimal numbers
2.200, 2.276, 2.291, 2.140, 2.260, 2.221
Here, all the numbers have 2 in the units place, so we just need to compare the decimals
The first digit after decimal is 2 in all the numbers except 2.140, thus it is the smallest.
Then, the second digit after decimal is 0 in 2.200, thus it is the next smallest number.
By similar logic, looking at the second digit after the decimal only we can arrange the remaining numbers as 2.221, 2.276, 2.260, 2.291.
Thus, the numbers ordered from least to greatest are- 2.14, 2.2, 2.221, 2.276, 2.26, 2.291.

Given:
Type A coffee cost $5.35 per pound
Type B Coffee cost $4.05 per pound
Keiko made total 166 pound of the blend of $780.85
Therefore,
[tex]5.35x + 4.05y = 780.85 \;\;\;\;\; -------equation (1)[/tex]
[tex]x + y = 166 \;\;\;\; ---------equation (2)[/tex]
simplify the equation (2),
[tex]y = 166-x[/tex]
Substitute the value of y in equation (1),
[tex]5.35x + 4.05 (166-x) = 780.85[/tex]
[tex]5.35x + 672.3 - 4.05x = 780.85[/tex]

Answers
In the first pair of numbers 15/x² + 6 is larger and in the second pair of numbers (s² + 2)/(s² + 1) is larger
What is Expression in Mathematics?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is two pairs of expressions. From the image given , we can write them as -
Pair 1 → f(x) = 15/x² + 6 and h(x) = 15/x² + 7
Pair 2 → f(s) = (s² + 2)/(s² + 1) and h(s) = (s² + 4)/(s² + 3)
We can compare which expression is larger in both the pairs without substituting any specific value as follows -
Pair 1 → f(x) = 15/x² + 6 and h(x) = 15/x² + 7.
The numerator is same in both the functions.
Now, for any value of x ∈ R → x² + 6 < x² +7 by 1. Therefore, f(x) > h(x)
Pair 2 → f(s) = (s² + 2)/(s² + 1) and h(s) = (s² + 4)/(s² + 3)
f(s) = (s² + 2)/(s² + 1) = [(s² + 1) + 1]/(s² + 1) = 1 + 1/(s² + 1)
h(s) = (s² + 4)/(s² + 3) = [(s² + 3) + 1]/(s² + 3) = 1 + 1/(s² + 3)
So, we can write that -
f(s) = 1 + 1/(s² + 1)
h(s) = 1 + 1/(s² + 3)
Now for any value of s → (s² + 1) < (s² + 3) by 2. So → 1/(s² + 1) > 1/(s² + 3). Therefore → 1 + 1/(s² + 1) > 1 + 1/(s² + 3). Finally, we can write -
(s² + 2)/(s² + 1) > (s² + 4)/(s² + 3)
Therefore, in the first pair of numbers 15/x² + 6 is larger and in the second pair of numbers (s² + 2)/(s² + 1) is larger.

A farmer has 120 bushels of apples to sell at his stand. he sells an average of 16 3/5 bushels each day. represent the total change in the number of bushels he has for sale after 7 days
Answers
The total change in the number of bushels he has for sale after 7 days = 116.2
In this question,
A farmer sells an average of 16 3/5 bushels each day.
We write above improper fraction 16 3/5 in proper fraction as 83/5
And the decimal form of given fraction 83/5 is:
83/5 = 16.6
After 7 days, he would sold (16 3/5) × 7 bushels.
We simplify an expression (16 3/5) × 7
(16 3/5) × 7 = 16.6 × 7
= 116.2
As a result, the farmer would have only 120 - 116.2 = 3.8 bushels for sale.
Therefore, the total change in the number of bushels he has for sale after 7 days = 116.2
