well, let's get the info first.
so going forth the Cheetah goes 70mph and going back it modestly does 40mph.
can we say that on average it did 55mph?
well, what's that? on average means, that in total if we sum all units up and divide them evenly by relevant intervals, that's our average value.
well, let's see both intervals, on is forth and another is back 2 intervals, and the speed values are 70 and 40, so the average will really be (70 + 40) ÷ 2 = 55, that is an average of 55mph, so yes, we can say that.
A)
since an hour is 60 minutes, the Cheetah is really doing 70 miles per 60 minutes, or we can say
[tex]70\cdot \cfrac{miles}{~~\begin{matrix} hour \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }\cdot \cfrac{~~\begin{matrix} hour \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }{60~minutes}\implies \cfrac{70}{60}\cdot \cfrac{miles}{minutes} \implies 1.1\overline{66}\frac{miles}{minutes}[/tex]

The cost of 4kg of radishes and 1. 5kg of carrots is £14. 80
The cost of 3kg of radishes and 2kg of carrots is £12. 50
Work out the cost of 1 carrots
Work out the cost of 1 radishes
The cost of one carrot is £1.6 and cost of one radish is £3.1 according to the quadratic equations we formed by the given data.
Here the cost of 4 kilo grams of radish and 1 and half kilo gram of carrot is £14.80.
Now, form a quadratic equation from the given data:
4[tex]\alpha[/tex]+1.5[tex]\beta[/tex]=14.80 --------(1)
Also given that the cost of 3kg of radishes and 2kg of carrots is £12. 50.
Similarly form a equation with that data:
3[tex]\alpha[/tex]+2[tex]\beta[/tex]=12.50 ----------(2)
Now simplify both equation 1 and 2
4[tex]\alpha[/tex]+1.5[tex]\beta[/tex]=14.80
3[tex]\alpha[/tex]+2[tex]\beta[/tex]=12.50
--------------------

Calculate the length of the legs of the triangle.
Answer: 5
Step-by-step explanation:
Find the distance travelled by rahul, if he takes 6 rounds of a square field of side=120m
The distance travelled by Rahul, if he takes 6 rounds of a square field of side = 120m is 2880 meters.
We are given that Rahul takes 6 rounds of a square field of side length 120m. To find the total distance he travels, we need to calculate the perimeter of the square field and multiply it by the number of rounds.
The perimeter of a square is the sum of the lengths of its four sides. Since the side length of the square field is 120m, the perimeter is:
4 * 120m = 480m
This is the distance Rahul covers in one round around the square field.
To find the total distance he covers in 6 rounds, we multiply the distance covered in one round by the number of rounds:
480m * 6 = 2880m
So, Rahul covers a total distance of 2880 meters.

For question 1,
James runs 400m in a day
In a week = 7 days
400m × 7 days = 2800m
To convert 2800m to km
1km = 1000m
So, 2800m/1000m
= 2.8 km
For question 2,
How far are the Town Center and the Park
3.5 km and 650m
650m to km
1km = 1000m
To km = 0.65km
The distance = 3.5km - 0.65km

What is the mean, and what does it tell you in terms of the problem?
3.1 feet; The value means the furthest the ball went.
3.875 feet; The value means that a typical throw of the ball results in 3.875 feet.
4.1 feet; The value means this measurement had the most occurrences.
4.65 feet; The value means that a typical throw of the ball results in 4.65 feet.
The mean would be 35 feet.
The mean tells us that the typical throw of the ball results in a distance of approximately 3.5 feet.
what is Mean?
In arithmetic, mean is the sum of all the added values of all the data in a set divided by the number of data in the set.
To find the mean of the distances, we need to calculate the sum of all the distances and divide by the total number of distances:
(20+25+25+31+33+34+41+41+45+50+56+67) / 12 = 425 / 12 = 35.42
Rounding to one decimal place, we get the mean distance of approximately 3.5 feet.
However, it's worth noting that the stem-and-leaf plot shows some variability in the distances, with some throws going as far as 6.7 feet and some as short as 2 feet.
So while the mean can provide us with a measure of central tendency, it doesn't tell the whole story about the distribution of the distances.
Therefore, The mean would be 35 feet. The mean tells us that the typical throw of the ball results in a distance of approximately 3.5 feet.

Find the total wingspan
Answer:
9.9 cm
Step-by-step explanation:
The right triangle has one-half the wing span as a leg.
The hypotenuse is 5.8cm and the other leg is 3cm
If we let the unknown leg of the triangle be x, by the Pythagorean theorem we know the sum of the squares of the two legs must be equal to the square of the hypotenuse .
So
x² + 3² = 5.8²
x² = 5.8² - 3²
= 33.64-9
= 24.64
x = √24.64
= 4.96
Total wingspan = 4.96 × 2 = 9.9 cm

C. Shading will be above the y=-2x+1 line but below the y= 3x-1
line.
D. None of the above
SUBMIT
Answer:
Step-by-step explanation:
The correct answer is C. Shading will be above the y=-2x+1 line but below the y= 3x-1 line.
The line y=-2x+1 is a line with a slope of -2 and a y-intercept of 1. It represents the solutions that are greater than -2x+1.
The line y=3x-1 is a line with a slope of 3 and a y-intercept of -1. It represents the solutions that are less than 3x-1.
So, when you graph both of these lines on the same coordinate plane, the solutions that satisfy both inequalities will be the region that is above the line y=-2x+1 but below the line y=3x-1, and this is the region that will be shaded.
Angle QRS is an equilateral triangle. If QR is seven less than twice x, RS is 61 less than five times x, and QS is 11 more than x, find the value of x and the measure of each side
The value of x is 18 and the measure of each side is:
QR = RS = QS = 29
What is called equilateral?An equilateral triangle is a triangle that has all its sides equal in length. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure. Therefore, it is also called an equiangular triangle, where each angle measure 60 degrees.
Now, According to the question:
Angle QRS is an equilateral triangle.
QRS is an equilateral triangle, thus all the three sides of the given triangle will be equal.
we have
QR = 2x - 7___(1)
RS = 5x - 61 ___(2)
QS = 11 + x_____(3)
Now, As all the sides of the triangle are equal, therefore
QR = RS = QS
⇒QR = RS
⇒2x - 7 = 5x - 61
⇒ -7 + 61 = 5x - 2x
⇒ 54 = 3x
⇒ x = 18
Put the value of x in above equations:
Thus, the measure of
QR = 2(18) - 7=29,
RS = 5(18) - 61 = 29 and
QS = 11 + 18 = 29.

Describe how the volume of three tennis balls, each with a diameter of 2.7 inches compares to the volume of their packaging, which is a cylinder that has the same diameter and a height of 8.1 inches. Explain or show your work.
Answer:
Step-by-step explanation:
The volume of the three tennis balls combined is approximately 4.88 cubic inches. The volume of the packaging cylinder is approximately 50.33 cubic inches. Thus, the volume of the three tennis balls is about 9.7% of the volume of their packaging cylinder.
To calculate this, we can use the formula for the volume of a sphere (V = 4/3 x π x r3) and the formula for the volume of a cylinder (V = π x r2 x h).
The radius of each tennis ball is half the diameter, or 1.35 inches. So, the volume of each tennis ball is 4/3 x π x (1.35)3 = 4.88 cubic inches.
The radius of the cylinder is the same as the diameter of each tennis ball, or 2.7 inches. The height of the cylinder is 8.1 inches. So, the volume of the cylinder is π x (2.7)2 x 8.1 = 50.33 cubic inches.
The volume of the three tennis balls is 4.88 x 3 = 14.64 cubic inches. The volume of the packaging cylinder is 50.33 cubic inches. Thus, the volume of the three tennis balls is 14.64 ÷ 50.33 = 0.097 = 9.7% of the volume of their packaging cylinder.

The film provides a vivid and moving account of their journey and the challenges they faced along the way, from beatings and arrests to bombings and arson attacks. Through interviews with surviving freedom riders and archival footage, the film sheds light on the bravery and determination of these activists and the impact they had on the civil rights movement.
The freedom riders were inspired by the nonviolent protest movement led by Dr. Martin Luther King Jr. and other civil rights leaders. They believed that segregation was a moral wrong and that they had a duty to resist it through nonviolent means. Despite the danger they faced, the freedom riders refused to back down, putting their lives on the line for the cause of justice and equality.
The bravery of the freedom riders had a profound impact on the civil rights movement. Their actions galvanized support for the cause and drew national attention to the issue of segregation. The freedom rides sparked a wave of protests and civil disobedience across the South, and helped to build momentum for the passage of the Civil Rights Act of 1964. This landmark legislation banned segregation in public places and made it illegal to discriminate against someone on the basis of race, color, religion, sex, or national origin.
The "Freedom Riders" documentary serves as a powerful reminder of the sacrifices made by those who fought for civil rights in the United States. It highlights the courage and determination of the freedom riders and the impact they had on the country. It is an important film that teaches us about the past and the struggles of those who fought for justice and equality.
In conclusion, the "Freedom Riders" documentary is a powerful reminder of the sacrifices made by those who fought for civil rights in the United States. It highlights the bravery and determination of the freedom riders and the impact they had on the civil rights movement. The film serves as a testament to the power of nonviolent protest and the importance of standing up for what is right, even in the face of opposition.

3cos²∅ (1+tan²∅) = 3
This equation involves trigonometric functions and can be simplified using trigonometric identities.
Starting with the right-hand side of the equation, we have 3. On the left-hand side, we have the expression 3cos^2(θ)(1 + tan^2(θ)).
We can simplify the expression as follows:
cos^2(θ) = 1 - sin^2(θ)
and
tan^2(θ) = sin^2(θ) / cos^2(θ)
Substituting these identities into the expression on the left-hand side, we get:
3(1 - sin^2(θ))(1 + sin^2(θ) / (1 - sin^2(θ))
Expanding the product and simplifying, we get:
3
Thus, the equation is true and holds true for all values of θ.
classify each peptide chain as part of a parallel β sheet, part of an antiparallel β sheet, either type of β sheet, or not part of a β sheet.
The first figure represents Antiparallel β sheet. Second figure is parallel β sheet. Third figure represents neither of the two types. The fourth figure is also parallel β sheet and the fifth figure represents both types.
Antiparallel and parallel β-sheets are two different arrangements of the β-strands in a protein structure.
In an antiparallel β-sheet, the direction of the peptide bonds in the individual β-strands is opposed to each other, meaning that the N-terminal end of one strand points in the opposite direction from the N-terminal end of the neighboring strand. The hydrogen bonds between the strands run perpendicular to the direction of the peptide bonds and hold the strands together.
In a parallel β-sheet, the direction of the peptide bonds in the individual β-strands is the same, meaning that the N-terminal end of one strand points in the same direction as the N-terminal end of the neighboring strand. The hydrogen bonds between the strands run parallel to the direction of the peptide bonds and hold the strands together.
Both antiparallel and parallel β-sheets play important roles in the structure and function of proteins, and are found in many different types of proteins, including enzymes, transport proteins, and structural proteins.
