If a pound of barley costs $8, how many ounces can be bought for $2.55?
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! (:

Answer:
∠P is the same as ∠Q . Angle = 106°
Step-by-step explanation:
Vertical angles
360-74-74= 212
212/2 = 106
- angle EQF and angle PQD are vertical angles, so both are equal.
- angle PQD and angleQPC are same-side interior angles, meaning they are supplementary.
so,
180 - 74 = 106
answer:
106°

What is the center of the circle with equation x^2 + y^2 - 10x +6y-2= 0
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).

A local hair salon has 6 2/3 gallons of shampoo to split among 5 hairdressers. How much shampoo will each hairdresser receive?
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

simon est parti de chez lui a 9h15 et est arrivee a son travail a 10h30 apres avoir parcourue 95km en voitue
Répondre:
76 km / heure
Explication étape par étape:
Étant donné que:
Heure à laquelle Simon a quitté la maison = 9 h 15
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
Distance / temps
95 km / 1,25 heure
= 76 km / h

Find the largest number which divides 94 and 76, leaving a remainder of 4.
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.

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.

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.
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
