The amount received by Ahmed is 168 gm.
What is Ratio?
The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio.
Here, let the amount received by Ahmed be 7x
and amount received by Babar be 3x
Total amount of sweets = 240 gm
Now, according to question,
7x + 3x = 240
10x = 240
x = 240/10
x = 24
Thus, the amount received by Ahmed is 7 X 24 = 168 gm and amount received by Babar = 3 X 24 = 72 gm.

To see why no one noticed time dilation until the twentieth century, consider the time dilation of a clock in an automobile moving past you at 30m / s (about 67mph for reference). What happens when you try to compute gamma for this problem? Write out the steps you take.
(PLLS)!!!
When we try to compute gamma, for this problem, the value of gamma is 1
To answer the question, we need to know what time dilation is.
What is time dilation?Time dilation is a phenomenon in special relativity in which there is an elongation of time due to the motion of an object.
Now, the time is given by t = γt₀ where
γ = gamma = 1/√[1 - (v/c)²] where v = speed of object c = speed of light and t₀ = proper timeThe value of gammaSince we need to compute gamma when the speed of the automobile moving past you is 30 m/s.
Given that
v = 30 m/s and c = 3 × 10⁸ m/sSubstiting these into γ, we have
γ = 1/√[1 - (v/c)²]
γ = 1/√[1 - (30 m/s/3 × 10⁸ m/s)²]
γ = 1/√[1 - (1/1 × 10⁷)²]
γ = 1/√[1 - (1 × 10⁻⁷)²]
γ = 1/√[1 - (1 × 10⁻¹⁴)]
γ = 1/√[1 - 0.00000000000001]
γ = 1/√0.99999999999999
γ = 1/1
γ = 1
So, when we try to compute gamma, the value of gamma is 1

We need radius
Let that be r
πr²=452.163.14r²=452.16r²=144r=√144r=12ftAnswer:
12 feet
Step-by-step explanation:
It asks how many feet away from the sprinkler can water be spread. Therefore, in this scenario, we require the radius.
Area of a circle :
Area (circle) = πr²
Solving :
⇒ 452.16 = 3.14 × r²
⇒ r² = 452.16 ÷ 3.14
⇒ r = √144
⇒ r = 12 feet
Find an equation of the tangent to the curve at the point corresponding to the given value of the parameter. X = t5 1, y = t6 t; t = −1
The equation of the tangent to the curve at the point corresponding to the given value of the parameter will be x + y = c.
How to calculate the tangent of the parameter curves at a point?The curves are given below.
x = t⁵ + 1 and y = t⁶ + t
Then differentiate the functions with respect to t, then we have
[tex]\rm \dfrac{dx}{dt} = 5t^4\\[/tex] ...1
and
[tex]\rm \dfrac{dy}{dt} = 6t^5 + 1[/tex] ...2
Divide equation 2 by equation 1, then we have
[tex]\rm \dfrac{\dfrac{dy}{dt} }{\dfrac{dx}{dt} } = \dfrac{dy}{dx} = \dfrac{6t^5 + 1}{5t^4}[/tex]
Then the slope of the equation at t = −1, then we have
dy/dx = [6(-1)⁵ + 1]/[5(-1)⁴]
dy/dx = (-6+1)/5
dy/dx = -5/5
dy/dx = -1
Then the equation of the tangent line will be
y = -x + c
x + y = c
Where c is a constant.

The length of a rectangle is four times the width. The perimeter of the rectangle is 45 inches. Write a system of equations that represents this problem. What is the area of the rectangle
Step-by-step explanation:
2×length + 2×width = 45
length = 4×width
now, we are using the second equation (a variable identity) in the first equation
2×4×width + 2×width = 45
8×width + 2×width = 45
10×width = 45
width = 45/10 = 4.5 in
length = 4×width = 4×4.5 = 18 in
the area of the rectangle is

A chandelier is suspended from the ceiling by two chains. one chain is 46cm long and forms an angle of 60o with the ceiling. the other chain 64cm long. what angle does the longer chain make with the ceiling?
The angle the longer chain makes with the ceiling is 38.5°
The two chains and ceiling form a triangle and with two sides and an angle, we use the sine rule to find the other angle
What is the sine rule?The sine rule states in any triangle with sides a, b, c and angles A, B and C, repsectively, we have that
a/sinA = b/sinB = c/sinC
Since one chain is 46cm long and forms an angle of 60° with the ceiling. the other chain 64cm long. So, we find the other angle.
So, a/sinA = b/sinB where
a = 46 cm, b = 64 cmA = other angleB = 60°The value of the other angleMaking A subject of the formula, we have
A = sin⁻¹(asinB/b)
So, substituting the values of the variables into the equation, we have
A = sin⁻¹(asinB/b)
A = sin⁻¹(46 cm × sin60/64 cm)
A = sin⁻¹(46 cm × 0.8660/64 cm)
A = sin⁻¹(39.84 cm/64 cm)
A = sin⁻¹(0.6225)
A = 38.49°
A ≅ 38.5°
So, the angle the longer chain makes with the ceiling is 38.5°

Answer:

Triangle ABC is similar to triangle DEC, because all angles in one triangle are equal to angles in the other triangle.
That means that corresponding sides have the same ratio. Side AB and side DE are corresponding sides. Since there are no unknowns we can calculate the ratio (scale factor).
Since we are looking for scale factor of triangle DEC to triangle ABC, we put side AB (which is in triangle ABC) in the numerator.

If a plumber chargers a call out fee of $85 plus $72 per hour how much would it cost for 3 hours?
Show working out pls
Answer:
$301
Step-by-step explanation:
Charge for 1 hour = $ 72
To find the cost for 3 hours, multiply hourly rate ($72) by 3
Charge for 3 hours = 72 * 3 = $ 216
Now, to find the total cost, add the charge for 3 hours and the fixed rate.
Total cost = fixed rate + charge for 3 hours
= 85 + 216

The data value that is an outlier in the data for boxes of cookies is: E. 56.
How to Determine Outliers in a Data?The simple rule is that values lower than Q1 - 1.5 × IQR and values greater than Q3 + 1.5 × IQR are outliers of a data distribution.
Given the data, 20, 23, 18, 4, 17, 21, 15, 56, find the Q1, Q3, and IQR of the data distribution:
First Quartile (Q1) = 15.5
Third Quartile (Q3) = 22.5
Interquartile Range (IQR) = 22.5 - 15.5 = 7
Q1 - 1.5 × IQR = 15.5 - 1.5 × 7 = 5
Q3 + 1.5 × IQR = 33
None of the values are lower than 5.

Rounded to the nearest whole number, the standard deviation of the data is 29.
How do we calculate the standard deviation of data?The following notations and formulas will be used in these calculations:
Mean = (sum of the values) / n
Variance = ((Σ(x - mean)^2) / (n - 1)
Standard deviation = Variance^0.5
Where:
n = number of values = 4
x = each value
Therefore, we have:
Mean = (65 + 75 + 100 + 130) / 4 = 92.50
Variance = ((65-92.5-)^2 + (75-92.50)^2 + (100-92.50)^2 + (130-92.50)^2) / (4-1) = 2,525 / 3 = 841.666666666667
Standard deviation = Variance^0.50 = 841.666666666667^0.5 = 29.011491975882

Think of the boundary as an electric fence you cannot touch, but can get closer and closer to. We aren't including boundary points directly because of the lack of "or equal to". The shading is above the boundary, due to the "greater than" sign.

A new pizza restaurant uses paid advertisement to increase pizza sales on Mondays. The table below is a record of the restaurant’s sales each Monday for the first quarter (13 weeks) of the paid advertisement.
Part A: Create a scatter plot to represent the data in the table. Then, draw the line of best fit, going through the points representing weeks 5 and 13. Be sure to label each axis, as well as to include the proper titles for the scatter plot.
Part B: Use the total sales for weeks 5 and 13 to write an equation for the line of best fit. In your final answer, include all of your calculations.
Part C: In terms of the slope of the equation for the lines of best, fit explain whether or not you think the paid advertisement is responsible for the restaurant's increase or decrease in pizza sales during the first quarter. Use complete senteneces in your answer.
Part D: Assuming that the pizza restaurant wishes to continue the paid advertisement for an additional quater, use the equation for the line of best fit to predict the restaurant's sales for the Monday of the 20th week.
A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two variables, with the resulting points showing any association (correlation) between the data set.
What is a line of best fit?A line of best fit is also referred to as a trendline and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any correlation between a data.
Part B.By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that an equation for the line of best fit is given by:
y = 22.214x + 291.27
Part C.Since the slope of the equation for the line of best fit is positive, the paid advertisement is responsible for the restaurant's increase in pizza sales during the first quarter.
Part D.Next, we would predict the restaurant's sales for the Monday of the 20th week as follows:
y = 22.214x + 291.27
y = 22.214(20) + 291.27
y = 444.28 + 291.27
y = $735.55.
