Answer:

A) 180 packets

B) €450

Step-by-step explanation:

A) There are 300 packets of 1 kg of sugar in a container.

3/5 of the total amount is:

3 / 5 * 300 = 180 packets

B) Each packet goes for €2.50.

3/5 of the total amount is 180 packets, therefore, 180 packets will go for:

2.5 * 180 = €450

Answer: 22.4 m/s

Step-by-step explanation:

Average speed can be calculated using the following formula:

Speed = [tex]\frac{Distance}{Time}[/tex]

Speed = 560m/25 seconds

speed = 22.4 m/s

Answer:

-4 See Below:

Step-by-step explanation:

When you have a system of equations, you need to solve for one variable, and subsitute that variable into the other equation to solve for the other variables value.

3x +6y = 30 In this case, it would be easier to solve for x.

3x= 30-6y  Divide both sides by 3

x= 10-2y

Now we substitute for x in the other equation.

5x- 4y = 22

5(10-2y)-4y=22

50-10y-4y=22

50-14y=22 Add 14y to both sides

50= 14y + 22 Subtract 22 from both sides

28 = 14y     Divide by 14 on both sides.

y = 2

Substitute y=2 and solve for x.

x = 10- 2y

x= 10-2*2

x= 10-4

x= 6

Now we know y=2 and x=6, so we can substitute them into x-5y to find its value.

x - 5y

= 6-5*2

=6-10

= -4

Answer:

Pytagora's Theorem

Step-by-step explanation

a = 4 m

b = 15 m

c = ?

a^2 + b^2 = c^2

√ a^2 + b^2 = c

a^2 = 16 m

b^2 = 225 m

√  16 + 225 = c

√  241 = 15.52 m

c = 15.52 m

Answer:

Step-by-step explanation:

The vertex lies on the axis of symmetry, so the axis of symmetry is x=3.  This is correct.  

Note that the second half of this problem has already been answered correctly.  The axis of symmetry is precisely halfway between the two roots and has equation x = 3 in the case of x = 2 and x = 4.

Add 5 to both sides

-2a>8

Divide both sides by 2

a<4

Answer:

top graph

Step-by-step explanation:

-2a - 5> 3

Add 5 to each side

-2a -5+5>3+5

-2a > 8

Divide each side by -2, remembering to flip the inequality

-2a/-2 < 8/-2

Answer: the first option A

Step-by-step explanation:

Answer:

Step-by-step explanation:

The question is

There is 11.73 kg of chocolate candies in the grocery store. The first customer bought 48 dag of candies. A second customer bought 4/5 of the remaining quantity. The last three customers bought the same amount of candy. How much chocolate did the last customers get?

Givens

Let's transform 48 dag to kilograms.

[tex]48dag \times \frac{1kg}{100dag}= 0.48 \ kg[/tex]

Therefore, the first costumer bought 0.48 kilograms of candies.

The remaining amount is: [tex]11.73kg-0.48kg=11.25kg[/tex]

Now, we need to multiply the remaining amount of candies with 4/5

[tex]\frac{4}{5} \times 11.25kg=9 \ kg[/tex]

Therefore, the second costumer bought 9 kilograms of chocolate candies.

At last, we need to find the new remaining part of candies, which is

[tex]11.25-9=2.25 \ kg[/tex]

Therefore, the last costumers got 2.25 kilograms of chocolate candies.

Answer:

? = 4.28

Step-by-step explanation:

We know that tan theta = opp side / adjacent side

tan 35 = 3 / ?

Multiply each side by ?

? tan 35 = 3

Divide each side by tan 35

? = 3/tan 35

?= 4.28444402

To the nearest hundredth

? = 4.28

Answer:

option A is the correct answer

Answer:

The number of sweatshirts for which cost and income are equal

Step-by-step explanation:

Let y₁ represent the revenue from selling "x" sweatshirts and y₂ represent the cost of producing "x" sweatshirts, solving the system:

[tex]y_1=35x\\y_2=-0.05(x-400)^2+9,492\\y_1=y_2\\35x=-0.05(x-400)^2+9,492\\-0.05(x-400)^2-35x+9,492=0[/tex]

The solution of the equation above yields the number of sweatshirts for which the cost of production (y₂ ) is equal to the revenue from sales (y₁).

Therefore, the solution represents the number of sweatshirts for which cost and income are equal .

The number of sweatshirts for which cost and income are equal and this can be determined by using the substitution method.

Given :

The following steps can be used in order to determine the solution of the system of the equation:

Step 1 - Write the given system of equations.

[tex]y = 35x[/tex]              ---- (1)

[tex]y = -0.05(x - 400)^2+9492[/tex]              ---- (2)

Step 2 - Now, substitute the value of 'y' in equation (2).

[tex]35x = -0.05(x - 400)^2+9492[/tex]

Step 3 - Simplify the above equation.

[tex]35x = -0.05x^2-8000+40x+9492[/tex]

Step 4 - Now, write the above equation in generalized quadratic form.

[tex]0.05x^2-5x-1492=0[/tex]

From the above steps, it can be concluded that the correct statement is given by option D).

Answer:

0.85% probability that the first two are good and the last three are spoiled

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the first two jugs is not important, as is not the order in which the last three are selected. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Desired outcomes:

2 spoiled, from a set of 43-11 = 32.

3 spoiled, from a set of 11.

So

[tex]D = C_{32,2}*C_{11,3} = \frac{32!}{2!(32-2)!}*\frac{11!}{3!(11-3)!} = 982080[/tex]

Total outcomes:

5 jugs from a set of 43.

[tex]T = C_{43,5} = \frac{43!}{5!(43-5)!} = 115511760[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{982080}{115511760} = 0.0085[/tex]

0.85% probability that the first two are good and the last three are spoiled
