Answer:
2.47 m
Step-by-step explanation:
247 cm /100 = 2.47 m
1 m = 100 cm
247 centimeters is equivalent to 2.47 meters
To convert centimeters to meters, we use the conversion factor that 100 centimeters equal 1 meter. This is because the prefix 'centi' in centimeter means 'one hundredth', so 100 centimeters make up 1 meter.
To find the number of meters in 247 centimeters, we divide 247 by 100, because there are 100 centimeters in a meter. This gives us:
247 cm ÷ 100 = 2.47 meters
Therefore, 247 centimeters is equivalent to 2.47 meters.
trey has a peanut allergy, so he eats granola bars that are nut-free. a box of nut-free granola bars cost $4.50 after a 10% discount. what is the original price of the box of granola bars
The original price of the granola bars before the 10% discount was $5.00. To determine this, the given discounted price was divided by 0.90, which represents the price after a 10% reduction.
The original price of a box of nut-free granola bars before the discount can be calculated by reversing the 10% discount process. Since Trey paid $4.50 after the discount, we can represent the original price as x. The discount applied to x would be 0.10 times x (which is how a 10% discount is calculated), and the price after the discount is x minus the discount. So the equation to solve is x - 0.10x = $4.50.
Simplify this equation to find x:
0.90x = $4.50.
Now, divide both sides of the equation by 0.90 to find x:
x = $4.50 / 0.90.
x = $5.00.
Therefore, the original price of the box of granola bars before the 10% discount was $5.00.

Find the minimum value of
C = 4x + 3y
Subject to the following constraints:
x 20
y20
2x + 3y > 6
3x – 2y = 9
x + 5y = 20
Final answer:
To find the minimum value of C given the constraints, one must plot these constraints, find the feasible region's vertices, evaluate C at each vertex, and select the minimum value obtained. The minimum value of C = 4x + 3y, given the constraints and the corrected understanding of them, is 29.
Explanation:
To find the minimum value of C = 4x + 3y subject to the given constraints, we need to first correct the constraints provided, as it seems there might be a misunderstanding in how they were presented. Assuming the constraints meant to be:
1. [tex]\(x \geq 0\)[/tex]
2. [tex]\(y \geq 0\)[/tex]
3. [tex]\(2x + 3y \geq 6\)[/tex]
4.[tex]\(3x - 2y = 9\)[/tex]
5.[tex]\(x + 5y = 20\)[/tex]
We will solve the system of equations (4) and (5) to find the values of x and y that satisfy these conditions, and then we will check if these values satisfy all other constraints including (3). If they do, we'll use these values to find C.
Solving the equations simultaneously:
From equation (4): 3x - 2y = 9
From equation (5): x + 5y = 20
Multiplying equation (5) by 3 to eliminate x, we get:
3(x + 5y) = 3(20)
3x + 15y = 60
Now, subtract equation (4) from this result to eliminate x:
3x + 15y - (3x - 2y) = 60 - 9
3x + 15y - 3x + 2y = 51
17y = 51
y = 3
Substitute y = 3 into equation (5) to find x:
x + 5(3) = 20
x + 15 = 20
x = 5
Now, check if [tex]\(x = 5\) and \(y = 3\) satisfy the constraint \(2x + 3y \geq 6\):[/tex]
[tex]\[2(5) + 3(3) \geq 6\][/tex]
[tex]\[10 + 9 \geq 6\][/tex]
[tex]\[19 \geq 6\] - This is true.[/tex]
Since x = 5 and y = 3 satisfy all the constraints, we can calculate \(C\):
C = 4x + 3y
C = 4(5) + 3(3)
C = 20 + 9
C = 29
Therefore, the minimum value of C = 4x + 3y, given the constraints and the corrected understanding of them, is 29.

Un observador se acerca con una velocidad de 15m/s a un parlante estático que está emitiendo un sonido con una frecuencia de 297 Hz. ¿Cuál es la frecuencia percibida por el observador?
Answer:
310 Hz
Step-by-step explanation:
This is a spanish language mathematical question.
We translate this to english:
An observer approaches a static speaker at 15 meters per second. The speaker is emitting a sound with a frequency of 297 Hz. What is the frequency perceived by the observer?
Solution:
This can be solved using doppler effect formula. Which is:
[tex]f=(\frac{c}{c+V_s})f_0[/tex]
Where
f is the observed frequency (297 Hz)
c is the speed of sound (343 m/s)
[tex]V_s[/tex] is the velocity of source (given as 15)
[tex]f_0[/tex] is what we want to find
Now, substituting, we solve:
[tex]f=(\frac{c}{c+V_s})f_0\\297=(\frac{343}{343+15})f_0\\297=(0.9581)f_0\\f_0=309.99[/tex]
Rounding,
We can say the perceived frequency would be around 310 Hz

Kendra is babysitting her cousins, who are quintuplets. At snacktime, Kendra puts 5 plates on the table. She cuts apples into slices and places an equal number of slices on each cousin's plate. There is a total of 35 apples slices on the plates.
Which equation can you use to find the number of apple slices s on each plate?
Answer:
Kendra is watching over 5 children. She wants to be sure that they each have an even number of apple slices. There are 35 apple slices total. She wants to take 35 and put it equally into 5 groups.
Your equation would be 5s=35, where s would be the total amount of apple slices on each plate.
To solve this equation you would divide both sides by 5 to get 7. s=7 (35/5=7)
Each quintuplet would be 7 apple slices.

In the last election, Candidate C received 15,000 fewer votes than candidate B. If a total of 109,000 votes were cast, how many votes did candidate B receive? What is the equation for this problem and what is the answer to it?
Answer:
B receives 62000 votes
C receives 47000 votes
Step-by-step explanation:
Let C be the vote for candidate C
Let B be the vote for candidates D
Let the total vote be T. Therefore,
C + B = T (1)
But C receives 15000 votes fewer than B ie
C = B —15000 (2)
Total votes, T = 109000
Substituting the value of C and T into equation 1
C + B = T
B — 15000 + B = 109000
Collect like terms
B + B = 109000 + 15000
2B = 124000
Divide both side by the coefficient B i.e 2
B = 124000/2
B = 62000
Putting the value of B into equation 2;
C = B —15000
But B = 62000
C = 62000 — 15000
C = 47000
B receives 62000 votes
C receives 47000 votes

On a container ship there were 30 small containers that each weighed 3 tons, 20 medium
containers that each weighed 5 tons, and 10 large containers that each weighed 8 tons.
Find the mean weight of the containers on this ship.
The mean weight of the containers on the ship is found by adding the total weight of all the containers (270 tons) and dividing by the total number of containers (60), giving a mean of 4.5 tons per container.
Explanation:In this problem, we are asked to find the mean weight of the containers on a ship. The mean is the average value of a set of numbers, found by adding all the numbers together and then dividing by the quantity of numbers.
First, let's compute the total weight of all the containers. The weight of the 30 small containers are 30 containers * 3 tons each = 90 tons. The weight of the 20 medium containers are 20 containers * 5 tons each = 100 tons. The weight of the 10 large containers are 10 containers * 8 tons each = 80 tons.
So, the total weight of all the containers is 90 tons + 100 tons + 80 tons = 270 tons. And the total number of containers is 30 + 20 + 10 = 60 containers.
So, the mean weight of the containers is 270 tons Total Weight / 60 = 4.5 tons/container. So, the mean weight of the containers on the ship is 4.5 tons.
