Answer:

226.1946711 cubic ft

Step-by-step explanation:

volume of cylinder = πr²h

diameter (d)=6ft

r= d/2 = 6/2=3ft

h= 8ft

putting all values in the formula and calculating the volume

Answer:

Hay 140 alumnos en dicha aula.

Step-by-step explanation:

Primero, debes encontrar la cantidad de alumnos que aprobaron que corresponde a 4/5 usando una regla de tres teniendo en cuenta que sabes que 1/5 corresponde a 21 que son los estudiantes que no aprobaron:

1/5  → 21

4/5 →  x

x=(4/5*21)/1/5

x=(84/5)/(1/5)

x=84*5/5*1

x=420/5

x=84

Ahora, puedes sumar el número de estudiantes que aprobaron con el número de estudiantes que no aprobaron para encontrar el total que estudiantes que asistieron al examen:

84+21=105

Después, dado que sabes que 105 estudiantes corresponde a 3/4 de los alumnos en un aula, puedes usar una regla de tres para encontrar el número de estudiantes en el aula:

3/4 → 105

1     →   x

x=(1*105)/(3/4)

x=(105/1)/(3/4)

x=105*4/1*3

x=420/3

x=140

De acuerdo a esto, la respuesta es que hay 140 alumnos en dicha aula.

Answer:

3x + 2 = 3

Step-by-step explanation:

3x + 2 = 3 Subtract 2 from both sides

3x = 1 Divide both sides by 3

x = 1/3

Answer:

111.678

Step-by-step explanation:

Answer:

First Space: 49

Second Space: 33

Third Space:-99

Fourth Space: -99

Fifth Space: 10

Sixth Space: -89

Step-by-step explanation:

First Space: for the first space you would do -7 times -7 because it is squared so you would get 49 because a negative and a negative and a negative make a positive.

Second Space: For the second space you have to do 49-16 because you already found the first space and the answer would be 33.

Third Space: For the third space you would do the answer you got from the second space which is 33 and multiply by -3 because -3 is outside the brackets. The answer would be -99.

Fourth Space: You would just put the same thing as the third space and put -99.

Fifth space: To find the fifth space you have to do 4 ÷ 2/5. To find this part you have to do 4 times the reciprocal (when you flip the fraction) and you would get 4 times 5/2. Then you can cross the denominator (bottom of the fraction) and make the 4 a 2 because 4 ÷ 2=2. Next you do 2 times 5 and get 10 as a answer.

Sixth Space: For the final answer you would use the fourth and fifth space. You would do -99+10 which is -89.

Hopefully this helps :)

Answer:

25 fudge centres, 20 nut clusters, 18 truffles, 6 of each type of chocolate

Step-by-step explanation:

Michel has a total of $15.00

So, if he only has to buy one type, we just divide the total amount by the price, like this:

[tex]\frac{15.00}{0.60}[/tex] = 25 fudge centres

[tex]\frac{15.00}{0.75}[/tex] = 20 nut clusters

[tex]\frac{15.00}{0.80}[/tex] = 18.75, so we round down = 18 truffles

If he buys the same of number of each type, we know that:

0.60x + 0.75x + 0.80x ≤ $15.00

2.15x ≤ 15.00

x ≤ 6.977...

This means that Michel can only buy 6 of each type of chocolate.

Answer:

If he buys only one type, he can buy 25 fudge centers OR 20 nut clusters OR 18 truffles.

The equations you can write to solve those are:

0.6f = 15

0.75n = 15

0.8t = 15

If he buys an equal number of each then

0.6f + 0.75n + 0.8t = 15

and

f = n = t

He can buy 6 of each without going over his budget.

Answer: -2x²+2x+3

Step-by-step explanation:

Factoring -2x2+2x+3

The first term is, -2x2 its coefficient is -2 .

The middle term is, +2x its coefficient is 2 .

The last term, "the constant", is +3

Step-1 : Multiply the coefficient of the first term by the constant -2 • 3 = -6

Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is 2 .

-6 + 1 = -5

-3 + 2 = -1

-2 + 3 = 1

-1 + 6 = 5

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Answer:

x = 45/2 = 22.5 cm

Step-by-step explanation:

2x + 45 = 90

2x = 90- 45= 45

.......

Answer:

The answer should be 75 if i did the math right

Answer:

Step-by-step explanation:

You have to add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

So in this case it would be:

46+56+64+64+72+76+77+82+94+96+99.

And the answer for the first step is: 826.

Next Step!

826 will have to be divided by 11.

Because there are 11 numbers that had to be added.

So 826÷11=75.
