What number do I put in.

Answer:

188.5 cubic inches

Step-by-step explanation:

V(cone) = 1/3πr²h

= 1/3π(3²)(2)

= 1/3(9)(2)π

= 6π

V(cylinder) = πr²h

= π(3²)(6)

= 54π

Total Volume = 6π + 54π or 60π

60π is approximately 188.5 cubic inches

Answer:

P = 10x+4

Step-by-step explanation:

The perimeter of a rectangle is given by

P = 2(l+w) where l is the length and w is the width

P = 2( 3x+2+ 2x)

Combine like terms

P = 2(5x+2)

Multiply by 2

P = 10x+4

Answer:

[tex]2x + 2(x - 3) = 18 \\ 2x + 2x - 6 = 18 \\ 4x = 24 \\ x = 24 \div 4 = 6 \\ y = x - 3 = 6 - 3 = 3[/tex]

Answer:

c

Step-by-step explanation:

The minimum and the x intercept are the same point.

Your answer is the second best answer. The definition of an x intercept is the point on a graph where y = 0. In this case, the graph begins to move in the opposite direction from the direction it was moving.

And so the x intercept just touches the x axis. Good enough. It is still classified as the x intercept because y = 0.

Answer:

[tex]5.8[/tex]

Step-by-step explanation:

Similar shapes also maintain a constant proportion of sides. Therefore, we can set up the following equation:

[tex]\frac{31}{43}=\frac{\text{KI}}{8}[/tex]

Solving, we get:

[tex]\text{KI}=\frac{8\cdot 31}{43}\approx \boxed{5.8}[/tex]

Answer:

1.33kg : 2kg : 1kg

Step-by-step explanation:

2kg : 3kg : 1.5 kg

Given data

We have the ratio

2kg : 3kg : 1.5 kg

Let us reduce the ratio further

2/1.5: 3/1.5 : 1.5/1.5

1.33kg : 2kg : 1kg

Hence the simplified ratio is 1.33kg : 2kg : 1kg

Answer:

54 years

Step-by-step explanation:

Given that :

Let :

Ann's age = x

Mary's age = x/2

Donald's age = x/3

x + x/2 + x/3 = 99

Take the L. C. M

(6x + 3x + 2x) / 6 = 99

11x / 6 = 99

11x = 99 * 6

11x = 594

x = 594 / 11

x = 54

Hence, Ann is 54 years

Answer:

Dados dos ángulos vecinos, ambos son complementarios si la suma de sus medidas es igual a 90° y suplementarios si esa suma de medidas es igual a 180°. Puesto que uno de los ángulos es el ángulo agudo mencionado en el enunciado, es decir, un ángulo cuya medida es mayor que 0° y menor que 90°. Entonces, el ángulo complementario debe ser inevitablemente menor que el ángulo suplementario.

Answer:

O no, because people in the bookstore are interested in purchasing books, so they do  not represent all shoppers in the mall

Step-by-step explanation:

In the bookstore, the best method which the store keeper wanted to adopt is actually not a sample representation of the population. This is because, since it would be a survey of those that interested in purchasing books as gifts, it should be able to factor in other purchasers in the mall rather than those who purchase from the bookstore only.

Doing this, would help to give an accurate representation of both group in the survey.

The sample space (total number of students) = 30

total number of freshmen = 7

the freshmen = the event considered

.....therefore

probability = 7/30

%probability = 7/30 × 100%

= 23.33% ~ 23%

The solution is, The required probability is 3/4= 75%, is the probability the student is a freshman.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

here, we have,

We have to compute the probability,

P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.

Determine the total number of juniors.

Juniors=2+6=8

Since the number of females who are junior is 6, determine the required probability.

P(Female|Junior)=6/8

=3/4

=75%

Therefore, the required probability is 3/4 = 75%.

Step-by-step explanation:

The distance between each point is 8.9, hope this helps!

Answer:

8

Step-by-step explanation:

if you wrote out A(n) correctly than the answer is 8

If these are separated like:

(6+8)*x, 4x+4+21, 4(2x+3), 6x+8x, 16(x+y+z), 8x+4+31, 4(x+2), and 6x+6y+6z...

Then it will be (6+8)*x with 6x+8x, 4x+4+21 with 8x+4+31, 4(2x+3) with 4(x+2), and 16(x+y+z) with 6x+6y+6z. Due to like terms, it only makes the most amount of sense.

Answer:

  a[1] = 3

  a[n] = 2×a[n-1] +1

Step-by-step explanation:

We observe the first differences are ...

  7-3 = 4

  15-7 = 8

  31-15 = 16

  63-31 = 32

The first differences increase by a factor of 2, so we expect the recursive formula will have a term that looks like "2×a[n-1]".

The second term is 2·3+1 = 7.

The third term is 2·7+1 = 15.

This suggests our recursive formula is ...

  a[1] = 3

  a[n] = 2×a[n-1] +1
