If a pound of barley costs $8, how many ounces can be bought for $2.55?
Answers
Answer: I believe the answer would be 5.1 ounces...
Step-by-step explanation:
To get this answer I used a proportion and transformed pounds into ounces. 1lb=16oz
x/16= 2.55/8
Cross multiply....
8x=40.8
And simplify!
x=5.1
So for $8 you can get a pound, for $2.55 you can get 5.1 ounces (or 5 ounces if needed in whole numbers)
Hope this helps! Good luck! (:

Grace scored n points in her first basketball game of the season. She scored 8 more points in her second game than in her first, 3 fewer points in her third game than in her second, and 11 more points in her fourth game than in her third, scoring a total of 25 points in her fourth game. How many points did Grace score in her first game?
Answers
Answer:
Grace scored 9 points in her first game.
Step-by-step explanation:
In her first game, she scored n points.
She scored 8 more points in her second game than in her first
So n + 8.
3 fewer points in her third game than in her second
So n + 8 -3 = n + 5
11 more points in her fourth game than in her third
n + 5 + 11 = n + 16
A total of 25 points in her fourth game.
This means that:
n + 16 = 25
n = 9
So
Grace scored 9 points in her first game.

Find the largest number which divides 94 and 76, leaving a remainder of 4.
Answers
Answer:
6 for 76 and 5 for 94
Step-by-step explanation:If you divide 76 with 6 the quotient will be 12 and the remainder will be 4 and if you divide 94 by 5 the quotient will be 18 and the remainder will be 4. Thank me later .
The largest number which divides 94 and 76, leaving a remainder of 4. is 18.
It is required to find the largest number.
What is factor?A number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.
Given:
we have to find the largest number which divide 94 and 76 leaving remainder 4 in each case.
According to given question we have
so let us subtract 4 from 94 and 76.
⇒ 94−4=90
⇒ 76−4=72
now lets find the HCF
⇒ prime factorization of 90 = 2 × 3 × 3 × 5
prime factorization of 72 = 2 × 2 × 2 × 3 × 3
now lets take out the common factors from both the cases
⇒ 2,3 and 3
x=2*3*3=18
∴ 18 is the number which will divide 94 and 76 leaving remainder 4 in each case.
Therefore, the largest number which divides 94 and 76, leaving a remainder of 4. is 18.

What is the center of the circle with equation x^2 + y^2 - 10x +6y-2= 0
Answers
Answer:
C(5, -3)
Step-by-step explanation:
Given the equation of circle;
x² + y² - 10x + 6y - 2 = 0
The general equation for a circle is given by the formula;
x² + y² + 2gx + 2fy + c = 0
Where the center is C(-g, -f)
To find the center, we would compare the two equations;
For the value of g.
2gx = -10x
2g = -10
g = -10/2
g = -5
To find the value of f.
2fy = 6y
2f = 6
f = 6/2
f = 3
Therefore, the center C(-g, -f) = (-(-5), -(3))
C(-g, -f) = C(5, -3).

The length (l) of a rectangular box is 5 centimeters more than twice its width (w).
Write an equation to represent the length of the rectangular box.
Part B
Find the length of the box if its perimeter is 100 centimeters.
Answers
Answer:
length of rectangular box = 2[w] + 5
length of rectangular box = 35 cm
Step-by-step explanation:
Given:
length (l)
width (w)
Perimeter = 100 centimetre
Computation:
Part A;
length of rectangular box = 2[width] + 5
length of rectangular box = 2[w] + 5
Part B;
Perimeter = 2[l+w]
100 = 2[2w + 5 + w]
100 = 6w + 10
w = 15 cm
length of rectangular box = 2[w] + 5
length of rectangular box = 2[15] + 5
length of rectangular box = 35 cm
A local hair salon has 6 2/3 gallons of shampoo to split among 5 hairdressers. How much shampoo will each hairdresser receive?
Answers
Answer:
1 1/3 gallons of shampoo
Step-by-step explanation:
The above question is calculated as:
5 hairdressers = 6 2/3 gallons of shampoo
1 hairdresser = x gallon
We cross Multiply
5 hair dressers × x gallon = 6 2/3 gallons × 1 hair dresser
x gallon = 6 2/3 gallons × 1 hair dresser/5 hair dressers
x gallons = 6 2/3 gallons ÷ 5
x gallons = 20/3 gallons ÷ 5
= 20/3 × 1/5
= 4/3
= 1 1/3 gallons of shampoo
Therefore, each hair dresser would receive 1 1/3 gallons of shampoo

Heure à laquelle Simon est arrivé au travail = 10h30
Distance domicile-lieu de travail = 95 km
La vitesse moyenne = (distance totale parcourue / temps total pris)
Temps total pris = 10h30 - 9h15 = 1 heure 15 minutes = 1 heure (15/60) = 1,25 heure

Step-by-step explanation:
I took the assignment
Cube roots of -1 lies in the region given in the best options are A. on real axis, B. quadrant 1, F. quadrant 4.
What is cube roots of -1?
Cube roots of -1 mean "finding solution of the equation z³ = -1 since the equation is of order 3, the equation has 3 roots in complex field."
According to the question,
Cube roots of -1 can written as [tex](-1)^\frac{1}{3}[/tex].
Step (1): Write the given number in polar form
x = [tex](cos 0 - i sin 0)^\frac{1}{3}[/tex]
Step (2): Add 2kπ to the argument
x = [tex](cos 2k\pi - i sin 2k\pi )^\frac{1}{3}[/tex]
Step (3): Apply [tex]De[/tex] [tex]Moivre's[/tex] theorem = [tex](cos \alpha + i sin\alpha) = (cos n\alpha + i sin\alpha )[/tex]
x = [tex]\frac{cos2k\pi }{3} - i sin \frac{2k\pi }{3}[/tex]
Step (4): Put k = 0,1,2 .... (n-1) [sin (-θ) = -sin θ, cos(-θ) = cos θ]
The three roots are
cos 0 - [tex]i[/tex] sin 0, cos [tex]\frac{2\pi }{3}[/tex] - [tex]i[/tex] sin [tex]\frac{2\pi }{3}[/tex], cos [tex]\frac{4\pi }{3}[/tex] - [tex]i[/tex] sin [tex]\frac{4\pi }{3}[/tex]
-1, [tex]-\frac{1}{2} - i\frac{\sqrt{3} }{2}[/tex], [tex]\frac{-1}{2} + i \frac{\sqrt{3} }{2}[/tex] are the three roots of cube roots of -1.
Clearly three roots lies in the regions of real axis, quadrant 1 and quadrant 4.
Hence, Cube roots of -1 lies in the region given in the best options are A. on real axis, B. quadrant 1, F. quadrant 4.

One year, the population of a city was 160,000. Several years later it was 140,800. Find the percent decrease.
Answers
Answer:
Percent decrease in population = 12%
Step-by-step explanation:
Given that:
Population of city = 160,000
Population of city after several years = 140,800
Difference= 160000 - 140800 = 19200
Percent decrease = [tex]\frac{Difference}{Population} * 100[/tex]
Percent decrease = [tex]\frac{19200}{160000}*100[/tex]
Percent decrease = 0.12 * 100
Percent decrease = 12%
Hence,
Percent decrease in population = 12%

Simplify 2a + 6b - 3(4a - b)
Answers
Answer:
Answer: -10a+9b (I think)
To do this let's start with all terms that have an ‘a’ in them. If we look at the equation we see ‘+4a’, ‘+2a’ and ‘-(-3a)’. This will come down to 4a+2a-(-3a). Since minus times a minus equals a positive, the simplified a term will become: 4a+2a+3a = 9a
Now we do the same for all terms with the ‘b’. We see ‘3b’, ‘-b’ and ‘-(-2b)’. This is equal to 3b-b+2b. This means that all terms with ‘b’ simplify to 4b.
Now we group all terms without a variable. Here we see ‘-6’ and ‘+4’. This is equal to -6+4 which results in -2.
Now on to the last step! Combining our results, in the form all ‘a’ terms + all ‘b’ terms + all terms without a variable. This results in:
9a + 4b -2
