27^1/3 b / 9^1/2 a
There is an image attached of the problem
Answers
Answer:
Step-by-step explanation:
a-b=2
[tex]\frac{27^{\frac{1}{3} b} }{9^{\frac{1}{2}a } } \\=\frac{(3^{3}) ^{\frac{1}{3} b} }{(3^{2} )^{\frac{1}{2} a} } \\=\frac{3^b}{3^a} \\=3^{b-a} \\=3^{-(-b+a)} \\=3^{-2}\\=\frac{1}{3^2} \\=\frac{1}{9}[/tex]

23/50 simplified in fraction form
Answers
The simplified fraction is 23/50.
We have,
To simplify the fraction 23/50, find the greatest common divisor (GCD) of the numerator (23) and the denominator (50), and then divide both the numerator and the denominator by the GCD.
The GCD of 23 and 50 is 1, as they have no common factors other than 1.
Now, divide both the numerator and the denominator by 1:
23 ÷ 1 = 23
50 ÷ 1 = 50
Thus,
The simplified fraction is 23/50.

What is the quadrilateral?The definition of a quadrilateral is a planar form with four sides, four vertices, and four angles. Concave and convex are the two primary kinds.
Type of quadrilateral are:
Trapezoid.Rectangle.Parallelogram.Rhombus.Square.Kite.A figure has vertices A = (0, 0), B = (1, 3), C = (0, 4), and D = (-1, 1).
The distance between AB is given as,
AB = √[(1 - 0)² + (3 - 0)²]
AB = √10 units
The distance between AD is given as,
AD = √[(-1 - 0)² + (1 - 0)²]
AD = √2 units

Kimberly wants to get a backpack that cost $35 it is now on sale for 15% off she has to pay 7.5% sales tax what is the sales price of the backpack
Answers
Answer:
$44.26
Step-by-step explanation:
The computation of the sales price is shown below:
Its cost is $35
There is a sale off i.e. 15% off
And, the sales tax rate is 7.5%
SO, the sale price is
= $35 × 100 ÷ 85 + ($35 × 100 ÷ 85) × 7.5%
= $41.17 + $41.17 × 7.5%
= $41.17 + $3.09
= $44.26
Hence, the sales price is $44.26
Parking at a large university has become a very big problem. University administrators are interested in determining the average parking time (e.g. the time it takes a student to find a parking spot) of its students. An administrator inconspicuously followed 250 students and carefully recorded their parking times. The university is interested in using the information from the sample of 250 students collected to learn information about the entire student parking population. Would this be an application of descriptive or inferential statistics
Answers
Answer:
Inferential statistic
Step-by-step explanation:
The art of making deductions or data driven predictions from statistical data refers to an aspect of statistics called Inferential statistics. Inferential statistics differs from descriptive statistics which is another aspect which focuses on presenting characteristics of data. Here, we make statistical deductions about the entire population from the results obtained about the sample statistic. In the scenario above, the statistic derived from the sample data will be used to make deductions about the general population of students who park in the university. Therefore, from the statistic obstaied from the sample, we infer about the population.

that 400 g of sausage and 500 g of dry pasta is enough for four people.
a) How much sausage will she need?
b) How much pasta will she need?
Answers
Answer:
a) 1000 grams
b) 1250 grams
Step-by-step explanation:
Find out how much grams of sausage and dry pasta she needs for each person.
4 people = 400 g
1 person = 400 ÷ 4 = 100 g (sausage)
4 people = 500 g
1 person = 500 ÷ 4 = 125 g (dry pasta)
Find out how much grams of sausage and dry pasta is needed for 10 people.
10 person = 100 x 10 = 1000g (sausage)
10 person = 125 x 10 = 1250g (dry pasta)
