Answer: 1/7 = 4/28 = 8/56
Step-by-step explanation: 7 timestables
Answer:
1/7=4/28=8/56
Step-by-step explanation:
From the pattern of the question we can see that the numerator of the second fraction is 4 and the previous fraction's numerator is 1 that means the fraction has been multiplied by 4. Therefore multiplying the numerator and denominator results in the answer 4/28. For the last fraction we can see that the denominator is 56 and is the double of 28 therefore doubling the whole second fraction we get our answer as 8/56. Overall equating all the three fractions we get the same answer 1/7 after minimizing the fraction.

The cost of the the 17 feet by 23 feet Turkish cloth given the constant of variation is TL14,467.
What is the cost?A variable varies jointly if the value of one variable depends on the value of two or more variables. In this question, if the length and width of the cloth increases, the cost of the cloth increases. Also, if the length and width of the cloth decreases, the cost of the cloth decreases.
The equation that represents joint variation is:
y = kab
Where:
y = dependent variable = cost of the Turkish cloth k = constant of variation a = dependent variable = length of the cloth b = dependent variable = widthTL3848 = k(13 x 8)
k = TL3848 / (13 x 8)
k = $37
The cost of 17 feet by 23 feet cloth :
37 x 17 x 23 = TL14,467

What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The negative symbol - , or, denotes subtraction. For instance, in the following image, there are 5 2 peaches, which means that 5 peaches have had 2 removed, leaving a total of 3 peaches.
Given Data
The record high temperature on January 15 is 41.5 Fahrenheit the record low temperature on that day is -16.8.
Difference = High temperature - Low temperature
Difference = 41.5 -(-16.8)
Difference = 41.5 + 16.8
Difference = 58.3
The difference in the record temperatures is 58.3° Fahrenheit.

A diagram of the side of Robert's barn is shown. If he decides to paint one side of the barn, how many square feet will Robert paint?
1. 254.5 ft^2
2. 310.5 ft^2
3. 391 ft^2
4. 805 ft^2
Robert will paint 310.5 square ft
The side of Robert's barn contains a triangle and a rectangle of which the dimensions are given in the diagram.
If Robert paint one side of the barn, then he needs to paint the triangle as well as the rectangle. So we need to find the area of the triangle and rectangle first.
For the triangle, base = 23 ft
height = 7 ft
Area of the triangle = 1/2 bh
= 1/2 x 7 x 23
= 80.5 square ft.
For the rectangle, length = 23 ft
width = 10 ft
Area of the rectangle = length x width
= 23 x 10
= 230 square ft.
Area Robert needs to paint = Area of the triangle + Area of the rectangel
= 80.5 + 230
= 310.5 square ft.

The one-time fling! Have you ever purchased an article of clothing (dress, sports jacket, etc.), worn the item once to a party, and then returned the purchase? This is called a one-time fling. About 5% of all adults deliberately do a one-time fling and feel no guilt about it! In a group of six adult friends, what is the probability of the following? (Round your answers to three decimal places.)
Using the binomial distribution, the probability of no one having done a one time fling is of 0.735 = 73.5%.
Binomial distributionThe mass density formula for the probability of x successes is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters of the formula are given as follows:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.In the context of this problem, the values of the parameters are as follows:
p = 0.05, as about 5% of all adults deliberately do a one-time fling and feel no guilt about it.n = 6, as there are six adult friends in the group.The probability that no one has done a one time fling is P(X = 0), hence the probability is calculated as follows:
P(X = 0) = (0.95)^6 = 0.735 = 73.5%.

Find the y-intercept of the line graphed by the equation 1/2x + y = 7. (0, 14) (14, 0) (7, 0) (0, 7)
The y-intercept of the line graphed by the equation [tex]\frac{1}{2} x+y=7[/tex] is (0,7)
Option (D) is correct.
The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.
The given equation is [tex]\frac{1}{2} x+y=7[/tex]
Converting the equation in Slope-intercept form, we get
[tex]y=-\frac{1}{2} x+7[/tex] ...(1)
Now, to find the y-intercept, substitute x = 0 in the equation and solve for the value of y
Putting x = 0 in equation (1), we get

A jet’s speed in still air is 240 mph. One day it flew 700 miles with a tailwind (the wind pushing it along) and then returned the same distance against the wind. The total flying time was 6 hours. Find the speed of the wind.
Speed of the wind for jet speed in still air 240mph and jet covers 700 miles with tailwind and same distance against the wind in total time of 6 hours is equal to 40mph.
As given in the question,
Given data:
Jet speed in still air = 240mph
Let x be the speed of the wind.
Speed with tail wind = 240 +x
Distance covered with tail wind = 700miles
Time taken by jet with tail wind
= Distance/ speed
= 700 / (240 +x) __(1)
Speed against the wind = 240 - x
Distance covered against the wind = 700miles
Time taken by jet against the wind
= Distance/ speed
= 700 / (240 - x) __(2)
Total time taken is 6 hours
[700 / (240 +x)] + [700 / (240 - x)] = 6
⇒ 700( 240 -x + 240 + x) = 6 (240 +x)(240 - x)
⇒ 700 ( 480) = 6 ( 240² -x²)
⇒ 700 (80) = 57600 -x²
⇒ x² = 57600 - 56000
⇒ x² = 1600
⇒ x = √1600
⇒ x= 40 mph
Therefore, speed of the wind for jet speed in still air 240mph and jet covers 700 miles with tailwind and same distance against the wind in total time of 6 hours is equal to 40mph.

We are told that

So, in terms of the graph, as we are taking the final value of f and adding 5, this means that we are moving the graph of f 5 units up. That is the graph of g(x) is the graph of f(x) shifted 5 units up

C>0, |u|=c is equivalent to u=
|u|=c is equivalent to u = c or u = -c.
Given that c > 0.
i.e., c is a positive number.
Then |u| = c. That is, absolute value of u = c, a positive number.
An absolute value function is defined by,
|u| = { u ; if u ≥ 0
{ -u ; if u < 0
The absolute value of any number, Positive or negative, is always a positive number.
So here |u| = c, with c > 0.
Comparing with the definition of absolute value function, c is either u or -u.
More clearly, c = u, when u ≥ 0 or c = -u , when u < 0.
Hence the value of c depends on u.
Thus, |u|=c is equivalent to u = c or u = -c.
