we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
In this problem
Let
x--------> the number of cans
y-------> the cost of a soup
so
when
substitute
the equation is
using a graph tool
see the attached figure
the answer in the attached figure
We are given that 76 persons can complete the job in 42 days.
We need to find the number of days will 56 persons do the same job.
Let us assume that in x number of days will 56 persons do the same job.
Number of days taken by 1 person to complete same work = 76 × 42 =3192 days.
56 person will take = = 57.
You did not attach any picture to solve this problem. We cannot calculate for the value of A’ and D’ without the correct graph. However, I think I found the correct graph (see attached), please attach it next time.
So we are given that the figure is dilated by a factor of, meaning that all of its end points are multiplied by 2. By this rule, all we have to do is to simply multiply the initial coordinates of A and D by 2 to get A’ and D’, that is:
A’ = (-1 * 2, -1 * 2) = (-2, -2)
<span>D’ = (2 * 2, -1 * 2) = (4, -2)</span>
Two figures are similar if one is the scaled version of the other.
This is always the case for circles, because their geometry is fixed, and you can't modify it in anyway, otherwise it wouldn't be a circle anymore.
To be more precise, you only need two steps to prove that every two circles are similar:
Now the two circles have the same center and the same radius, and thus they are the same. We just proved that any two circles can be reduced to be the same circle using only translations and scaling, which generate similar shapes.
Recapping, we have:
So, we passed from X to X' to X'', and they are all similar to each other, and in the end we have X''=Y, which ends the proof.
Answer: The correct option is
(A)
Step-by-step explanation: Given that Juan can download new songs for $1.29 each.
We are to write an equation to show how many songs he can download for $10.00.
Let x represents the number of songs that Juan can download for $10.00.
Then, according to the given information, the equation can be written as follows :
Thus, the required equation is
Option (A) is CORRECT.
