Answer:
.75? A pair of jeans sells for $36 after a 25% discount. What is the original price of the jeans? x-0.25x=36
Step-by-step explanation:
$36. Explanation: To find the sale price we can set up a proportion. 25/100 = x/48. ... Then we subtract this discount from the original price yielding 48 – 12 = 36; thus, she ... This cost will be equal to the percent remaining after the discount.

Answer:
every group of her community
Step-by-step explanation:
To get an appropriate sample for her survey, she needs to survey people from various groups of the community.
If she surveys only dog owners, even only pet owners, chances are most people in that group would be in favor of the park, biased sample.
If she surveys only non-pet owners, the results will most likely show a minority of support.
The pet owners (or just dog owners) should be surveyed in a relative proportion of the general population of the community, so their opinion is neither over-weighted nor under-weighted in the results.

Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.
