nadiyah found the circumference of a circle with a diameter of 4.9 in to be 20in. is her answer reasonable? explain
The circumference of circle is given by :
[tex] C =2\pi r [/tex]
where r is radius of circle and pi =3.14
Radius = half of diameter
Radius = (1/2) *4.9 = 2.45 in.
Now let us plug the value of radius in the formula for circumference.
[tex] C =2(3.14)(2.45) [/tex]
C = 15.386 inches
But circumference found by Nadiyah is 20 inches.
So the circumference found by Nadiyah is incorrect as correct one is 15.386 inches.
John has 8/9 of a gallon of apple cider vinegar. If it takes 1/7 of a gallon of vinegar to make a batch of collard greens, how many batches can john make?
John can make 6 whole batches of collard greens with 8/9 of a gallon of apple cider vinegar, accounting for each batch requiring 1/7 of a gallon of vinegar.
The question asks how many batches of collard greens John can make with 8/9 of a gallon of apple cider vinegar, considering that each batch takes 1/7 of a gallon.
To find the answer, divide the total amount of vinegar John has by the amount of vinegar required for one batch:
Total amount of vinegar John has: 8/9 gallon
Amount of vinegar required for one batch: 1/7 gallon
Now, we use division to find out how many batches can be made:
(8/9), (1/7)
Multiply the first fraction by the reciprocal of the second fraction: (8/9) * (7/1)
Simplify the multiplication: (8 * 7) / (9 * 1)
Calculate the result: 56/9
Finally, we determine how many whole batches John can make, since partial batches are generally not considered. As 56/9 is equal to 6 with a remainder, John can make 6 whole batches of collard greens.

A can of juice has a diameter of 6.6 centimeters and a height of 12.1 centimeters. What is the total volume of a six pack of juice cans
To find the total volume of a six-pack of juice cans, calculate the volume of one can using the cylinder volume formula, [tex]V = \pi r^2h[/tex], and multiply by six. One can's volume, with a diameter of 6.6 cm and a height of 12.1 cm, is approximately 414.18 [tex]cm^3[/tex]. Multiplying by six gives a total volume of approximately 2485.08 [tex]cm^3[/tex] for the six-pack.
To calculate the total volume of a six-pack of juice cans, we first need to find the volume of a single can and then multiply that by six, since a six-pack contains six identical cans.
First, let's find the volume of one can using the formula for the volume of a cylinder [tex]V = \pi r^2h[/tex], where r is the radius and h is the height.
Given the diameter of a juice can is 6.6 centimeters, the radius r is half of that, which is 3.3 centimeters. The height h is 12.1 centimeters. Therefore, the volume of one can is:
[tex]V = \pi (3.3 cm)^2(12.1 cm) = \pi (10.89 cm^2)(12.1 cm) = \pi (131.769 cm^3) = 414.18 cm^3[/tex]
Now, to find the total volume for a six-pack, we multiply the volume of one can by six:
Total volume = 6 × 414.18 [tex]cm^3[/tex] ≈ 2485.08 [tex]cm^3[/tex]
Thus, the total volume of a six-pack of juice cans is approximately 2485.08 cubic centimeters.

Answer:
A reflection is a transformation that maps point P in a figure, over a line AB, such that for point C at the intersection of AB and PP', PC = PC' and m∠ACP = 90°
Step-by-step explanation:
After the reflection of P across the line AB, P' is created, where PP' and AB are perpendicular. Given that point C is at the intersection of the lines, then m∠ACP = 90° and PC = PC'.

please answer fast
Answer:
For 1: The wave speed of the wave is 30 m/s
For 2: The wave speed of the wave is 5 m/s
For 3: The frequency of the wave is 40 Hz
For 4: The frequency of the wave is 400 Hz
For 5: The frequency of the wave is 300 Hz
For 6: The wavelength of the wave is 0.773 m
For 7: The wavelength of the wave is 0.386 m
For 8: The wavelength of the wave is 0.625 m
For 9: The wave speed of the wave is 100 m/s
For 10: The wave speed of the wave is 50 m/s
Step-by-step explanation:
Wave speed is defined as the product of its wavelength and frequency.
Mathematically,
[tex]\text{Wave speed}=\lambda\times \nu[/tex]
where,
[tex]\lambda [/tex] = wavelength of the wave
[tex]\nu [/tex] = frequency of the wave
For 1:We are given:
[tex]\lambda =0.30m\\\\\nu=100Hz[/tex]
Putting values in above equation, we get:
[tex]\text{Wave speed}=0.30\times 100=30m/s[/tex]
Hence, the wave speed of the wave is 30 m/s
For 2:We are given:
[tex]\lambda =0.10m\\\\\nu=50Hz[/tex]
Putting values in above equation, we get:
[tex]\text{Wave speed}=0.10\times 50=5m/s[/tex]
Hence, the wave speed of the wave is 5 m/s
For 3:We are given:
[tex]\lambda =0.50m\\\\\text{Wave speed}=20m/s[/tex]
Putting values in above equation, we get:
[tex]20/s=0.50m\times \nu\\\\\nu=\frac{20}{0.50}=40s^{-1}[/tex]
Hence, the frequency of the wave is 40 Hz
For 4:We are given:
[tex]\lambda =0.20m\\\\\text{Wave speed}=80m/s[/tex]
Putting values in above equation, we get:
[tex]80/s=0.20m\times \nu\\\\\nu=\frac{80}{0.20}=400s^{-1}[/tex]
Hence, the frequency of the wave is 400 Hz
For 5:We are given:
[tex]\lambda =0.40m\\\\\text{Wave speed}=120m/s[/tex]
Putting values in above equation, we get:
[tex]80/s=0.20m\times \nu\\\\\nu=\frac{120}{0.40}=300s^{-1}[/tex]
Hence, the frequency of the wave is 300 Hz
For 6:We are given:
[tex]\nu =440Hz\\\\\text{Wave speed}=340m/s[/tex]
Putting values in above equation, we get:
[tex]340/s=\lambda\times 440\\\\\lambda=\frac{340}{440}=0.773m[/tex]
Hence, the wavelength of the wave is 0.773 m
For 7:We are given:
[tex]\nu =880Hz\\\\\text{Wave speed}=340m/s[/tex]
Putting values in above equation, we get:
[tex]340/s=\lambda\times 880\\\\\lambda=\frac{340}{880}=0.386m[/tex]
Hence, the wavelength of the wave is 0.386 m
For 8:We are given:
[tex]\nu =400Hz\\\\\text{Wave speed}=250m/s[/tex]
Putting values in above equation, we get:
[tex]250/s=\lambda\times 400\\\\\lambda=\frac{250}{400}=0.625m[/tex]
Hence, the wavelength of the wave is 0.625 m
For 9:We are given:
[tex]\lambda =2.0m\\\\\nu=50Hz[/tex]
Putting values in above equation, we get:
[tex]\text{Wave speed}=2.0\times 50=100m/s[/tex]
Hence, the wave speed of the wave is 100 m/s
For 10:We are given:
[tex]\lambda =0.50m\\\\\nu=100Hz[/tex]
Putting values in above equation, we get:
[tex]\text{Wave speed}=0.50\times 100=50m/s[/tex]
Hence, the wave speed of the wave is 50 m/s

Enter your answer rounded to the nearest whole number in the box.
The answer is 854 for sure. I did the test and got it all right.
Answer:
854 customers.
Step-by-step explanation:
An online store randomly samples three groups of 100 customers on which delivery method they use. The data shows the results of the three samples.
Overnight 2-day Standard Total
Group (1) 27 20 53 100
Group (2) 32 17 51 100
Group (3) 34 19 47 100
Total customers 93 56 151 300
We have to calculate the number of people who will use overnight delivery.
Out of 300 customer there are 93 people who would use overnight delivery, so the percentage = [tex]\frac{93}{300}[/tex] × 100 = 31%
The online store has 2755 customers one day.
Therefore, 31% of the 2755 customers = [tex]\frac{31}{2755}[/tex] × 100 = 854.05 ≈ 854 customers.
854 customers would use overnight delivery.

In a square of a side length s, what is the length of a diagonal?
Final answer:
The length of the diagonal in a square with side length s is s√2, calculated by using the Pythagorean theorem which relates the side lengths of a right triangle.
Explanation:
To find the length of a diagonal in a square with side length s, we can use the Pythagorean theorem. In a square, the diagonal splits the square into two right triangles. Therefore, the length of the diagonal can be seen as the hypotenuse of a right triangle where the other two sides are both of length s. The Pythagorean theorem tells us that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).
Here is the step-by-step solution using the Pythagorean theorem:
Let the side length of the square be s.
Since the sides of the square are equal, the lengths of the two sides of the right triangle (formed by the diagonal) are also s.
According to the Pythagorean theorem, the square of the diagonal length d is d² = s² + s².
This simplifies to d² = 2s².
Take the square root of both sides to find the length of the diagonal d = √(2s²).
Therefore, the length of the diagonal is d = s√2.

Which is C= 100w/l solved for w?
A.)W=100CL
B.)W= LC/100
C.)W= 100C/L
D.)W= 100/LC
Final answer:
To solve for 'w' in the equation C = 100w/l, multiply both sides by 'l' and then divide by 100, resulting in 'w = Cl/100', which is option B.
Explanation:
To solve the equation C = 100w/l for w, we need to isolate w on one side of the equation:
Multiply both sides by l to get Cl = 100w.
Divide both sides by 100 to isolate w, which gives us w = Cl/100.
Therefore, the equation solved for w is w = Cl/100, which corresponds to option B.) W = LC/100.
