Let's the length to be x,

then the width is 8x - 2.

Perimeter of a rectangle = 2*Width + 2*Length

Perimeter of the rectangle = 2(8x-2) + 2x = 16x - 4 + 2x = 18x - 4

Ar the same time, Perimeter of the rectangle = 88.

So, we can write

18x - 4 = 88

18x = 84

9x=42

x= 42/9 cm (length) or ≈ 4.67 cm (length)

8x - 2 = 8*42/9 - 2 ≈ 35.33 cm (width)

otez555 [7]

Answer:

350 kg per hectare is equal to 350 / 10 = 35 g/m²

Tanya [424]

Answer:

Sampling is necessary because researchers in the social sciences almost never have enough resources — time or money — to collect information about the entire set of subjects of interest to them.

Step-by-step explanation:

Sampling is done because you usually cannot gather data from the entire population. Even in relatively small populations, the data may be needed urgently, and including everyone in the population in your data collection may take too long.

What other information do you need in order to prove the triangles congruent using the SAS Congruence Postulate?
Mazyrski [523]

Answer:

<CBA = <CDA

Step-by-step explanation:

Using <CBA = <CDA and Base angle theorem, you can say that AB = AD.

Now you have <CBA = <CDA, AB = AD, and CB = CD. These prove SAS.

Samuel pays $20 for a shirt that is on sale. If he saved $5, what is the percent of the discount?
mamaluj [8]
Hi Kyliebreland!
So, If he saved $5 then we do $20 divided by $5 which gives 4 so now we split 100% into 4 pieces which gives us 25%.
Hope this helps!
