For peanut, the cost is ratio is
[tex]\dfrac{5}{3}[/tex]
For beef, the ratio is
[tex]\dfrac{7}{4.2}[/tex]
If we take cross product of these items,
[tex]\dfrac{5}{3}=\dfrac{7}{4.2}\\\\5\times 4.2=3\times 7\\\\21=21[/tex]
It implies, that the sale is in true proportion. From the cross product, we find that it is equal.

Monsieur Anatole est un artisan spécialiser dans la fabrication de colliers. Il dispose 3 717 perles rouges et de 2 205 perles blanches. En utilisant toutes ses perles, il réalise au maximum de colliers identique. La réalisation de chaque collier lui coute 9,84 €. Un deuxième artisan, Monsieur Bernards, utilise la totalité de ces 1472 perles rouges et 2 898 perles blanches pour fabriquer un maximum de colliers identiques. La fabrication d'un collier lui revient à 8,48 €. Les deux artisans décident de fixer le prix de vente de chaque colliers selon la constitution, à savoir : 22 centimes d'euro par perle rouge et 13 centimes par perles blanches. Sur la vente d'un collier, quel artisan réalise le meilleure bénéfice ?
Answer:
Sur la vente d'un collier, l'artisan qui a fait le meilleur profit était Monsieur Bernard
Step-by-step explanation:
a) Pour Monsieur Anatole
Nous trouvons le plus grand diviseur commun de 3717 et 2205
Par conséquent, le plus grand diviseur commun = 63
Le nombre de colliers qu'il a fabriqués = 63
Découvrir combien de perles rouges et blanches il a utilisées
Pour les perles rouges =
= 3717/63 = 59 perles
Pour les perles blanches
= 2205/63 = 35 perles blanches
il fabrique 63 colliers avec 59 perles rouges et 35 perles blanches
On nous dit dans la question que:
Les deux artisans décident de fixer le prix de vente de chaque collier selon la constitution, à savoir: 22 centimes d'euro par perle rouge et 13 centimes par perle blanche.
Le prix de vente du collier =
0,22 × 59 + 0,13 × 35 = 17,53 €
Prix de revient = 9,84 €
Le profit est calculé comme suit:
17,53 € - 9,84 € = 7,69 €
Nous calculons le pourcentage de profit
= Bénéfice / Prix de revient × 100
= 7,69 / 9,84 × 100
= 78,150406504%
= 78,2%
b) Pour Monsieur Bernard
Le GCD de 1472 et 2898 = 46
Par conséquent, il a fait 46 colliers
Le nombre de perles rouges = 1472/46
= 32 perles rouges
Le nombre de perles blanches = 2898/46
= 63 perles blanches
Les deux artisans décident de fixer le prix de vente de chaque collier selon la constitution, à savoir: 22 centimes d'euro par perle rouge et 13 centimes par perle blanche.
Le prix de vente de chaque colliers = 32 × 0,22 + 63 × 0,13 = 15,23 €
Le coût Prix du collier = 8,48 € chacun
Le profit qu'il a réalisé = 15,23 € - 8,48 €
= 6,75 €
Nous calculons le pourcentage de profit
= Bénéfice / Prix de revient × 100
= 6,75 / 8,48 × 100
= 79,5990566%
= 79,6%
Sur la vente d'un collier, l'artisan qui a fait le meilleur profit était Monsieur Bernard
Whats the factored form of the trinomial 2x^2-26x-60
Answer: Plz mark me brainlest
Step-by-step explanation:
You can factor out a 2, so do that first
2(x^2 - 13x + 30) = 0
Now look at x^2 - 13x + 30. Since you have a positive last term and a negative middle term, then you're looking for something in the form of (x - ?)(x - ?). We have to find two numbers whose product is 30 and whose sum is 13. The numbers must be 10 and 3:

Solve the equation
3/2 (2 - 6x) + 1 = 3 – 5x.
Answer:
x= 1/4
Step-by-step explanation:
3/2 (2−6x)+1=3−5x
(3/2) (2)+ (3/2) (−6x)+1=3+−5x
3+−9x+1=3+−5x
(−9x)+(3+1)=−5x+3
−9x+4=−5x+3
−9x+4+5x=−5x+3+5x
−4x+4=3
−4x+4−4=3−4
−4x=−1
YOU SUBTRACT -4 ON BOTH SIDES SO YOU'LL GET X= 1/4
Answer:
x= 1/4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3/2(2−6x)+1=3−5x
(3/2)(2)+(3/2)(−6x)+1=3+−5x (Distribute)
3+−9x+1=3+−5x
(−9x)+(3+1)=−5x+3 (Combine Like Terms)
−9x+4=−5x+3
−9x+4=−5x+3
Step 2: Add 5x to both sides.
−9x+4+5x=−5x+5x+3
−4x+4=3
Step 3: Subtract 4 from both sides.
−4x+4−4=3−4
−4x=−1
Step 4: Divide both sides by -4.
−4x/-4 −4/-4=−1/−4
x= 1/4

Matt is purchasing a new tablet computer at a 20% markdown. After the discount is taken, the tablet is subject to a 6% state sales tax. How would you find the total amount Matt must pay after the markdown and tax?
Multiply the original price by 0.86.
First find the 20% markdown price and the tax on the original price, and then add the new price to the tax.
Find the tax, and then take 80% off the tax and the original price.
First find the 20% markdown price and subtract it from the original price. Then find 6% of the discounted price to get the tax. The tax plus the discounted price is the final price.

36 3/4 gallons of water come out of a hose in 15 minutes. Write the ratio in fractional form and determine the water rate in gallons per hour. Group of answer choices 147 gallons per hour 73.5 or 73 1/2 gallons per hour 36.75 or 36 3/4 gallons per hour not possible
Answer:
147 gallons per hour
Step-by-step explanation:
Given:
36 3/4 gallons = 15 minutes
Determine the water rate in gallons per hour
1 hour = 60 minutes
60 minutes / 15 minutes = 4
Multiply both a of the proportion by 4
36 3/4 × 4gallons = 15 minutes × 4
147/4 × 4 gallons = 60 minutes
147 gallons = 60 minutes
147 gallons per hour
The correct answer = 147 gallons per hour

Which statement justifies why ∠FBE measures 50°? Given: angles ABD and DBC are complementary
Answer:
If two angles are vertical angles, then they are congruent.
Step-by-step explanation:
If two angles are vertical angles, then they are congruent- this justifies why ∠FBE measures 50°.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
Here, given that,
angles ABD and DBC are complementary
Now, we get,
Hence, If two angles are vertical angles, then they are congruent- this justifies why ∠FBE measures 50°.

How many square yards of carpet
are needed to cover the floor of
a room that is 18 feet long and
12 feet wide? (1 yd = 3 ft)
The area of the floor required to cover using carpet is equal to 24 square yards .
To calculate the area of the room in square yards,
convert the dimensions from feet to yards and then find the product of the length and width.
1 yard (yd) = 3 feet (ft)
Room length in yards
= 18 feet / 3 feet/yd
= 6 yards
Room width in yards
= 12 feet / 3 feet/yd
= 4 yards
Now, find the area of the room in square yards:
Area = Length × Width
Area = 6 yards × 4 yards = 24 square yards
Therefore, 24 square yards of carpet area required to cover the floor of the room.

Which statement describes the sequence −9, −3, 3, 9, 15?
A. An arithmetic sequence with common difference −9
B. An arithmetic sequence with common difference 3
C. An arithmetic sequence with common difference 6
D. Not an arithmetic sequence
Answer:
C. An arithmetic sequence with a common difference of 6.
Step-by-step explanation:
A is incorrect because the common difference is not -9 (not constant).
B is incorrect because the common difference is not 3 (not constant).
C is the correct answer because the common difference is 6 (constant).
D is incorrect because this is an arithmetic sequence.
-------------------------------------------------------------------------------------------------------
-9 + 6 = -3
-3 + 6 = 3
3 + 6 = 9
9 + 6 = 15

The progression −9, −3, 3, 9, 15 is an arithmetic sequence with a common difference of 6. The correct option is C.
What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.
Given series is −9, −3, 3, 9, 15.
The common difference is calculated as,
-9 + 6 = -3
-3 + 6 = 3
3 + 6 = 9
9 + 6 = 15
As above it is observed that with the common difference of 6 we found the series, −9, −3, 3, 9, 15.
Therefore, the progression −9, −3, 3, 9, 15 is an arithmetic sequence with a common difference of 6. The correct option is C.
