Production shows that only 3 of the first 10 phones are working which is 30% of the phones describe how the percentage other working phones changes if the 11th and 12th phone won't work correctly
Answers
Answer:
If you have 10 phones, this is the 100%
then:
10 = 100%
Now we know that only 3 of them work correctly, then the percentage of pones that works correctly can be related to:
3 = X%
To find the value of X%, we can take the quotient of the equations:
3 = X%
and
10 = 100%
We ge:
(3/10) = (X%/100%)
We solve this for X and we get:
(3/10)*100% = X% = 30%
As we already know.
Now let's see how this percentage changes if we add more phones that do not work correctly.
Now we add another phone that does not work, so we have a total of 11 phones and 3 of them work.
then:
3 = X%
11 = 100%
The quotient is:
(3/11) = (X%/100%)
(3/11)*100% = X% = 27.3%
If we add another phone, now we have 12 phones and only 3 of them works, then 12 is the 100%, and we have the equations:
3 = X%
12 = 100%
Then we get:
(3/12) = X%/100&
(3/12)*100% = X% = 25%

Scale factor = 3
Step-by-step explanation:
Using similar triangles
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
Expand
3x+30 = 27x-90
3x-27x = -90 - 30
-24x = -120
x = 120/24
x = 5
For the larger triangle;
AC = 3x-10
AC = 3(5)-10
AC =15-10
AC = 5
AB = x+10
AB = 5+10
AB = 15
For the scale factor;
Since AT/AG = AB/AC
9/15 = 3/5
3*3/5*3 =3/5
Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3

The dimensions of a rectangular community garden are 47 ft by 27 ft. The gardeners plan to divide the garden into equal-sized square plots. What is the greatest possible side length of each square plot? Use pencil and paper. How many square plots will there be with this side length? What will be the total area of the square plots? Explain how you can use the total area to check your work.
Answers
Answer:
the greatest possible length of each square plot is 1 ft.
1,269 square plots
Step-by-step explanation:
Since the plots are going to be squares then the width and length need to be the same. This means that the largest size of these plots would be calculated as the largest common divisor of the length and width of the garden. In this scenario, since 47 only has two divisors 1 and 47, and 27 is not divisible by 47 then the GCD of these two numbers would be 1. Meaning that the greatest possible length of each square plot is 1 ft.
To calculate the total number of plots needed we divide the square footage of the garden by the square footage of each individual plot like so...
47 * 27 = 1,269 sq. ft.
1 * 1 = 1 sq. ft.
1,269 / 1 = 1,269 plots
Finally, we see that we need a total of 1,269 square plots to cover that same area of the garden.

Therefore,
