Answer:

3179.25

Step-by-step explanation:

Hello!

To find the volume of a cylinder we use the equation

$V = \pi r^{2} h$

V is volume

r is radius

h is height

Put in what we know. It is says to use pi as 3.14

$V = 3.14 * 7.5^{2} *18$

Solve

V = 3.14 * 56.25 * 18

V = 3179.25

Hope this Helps!

The number of his next 42 field goals the kicker will not make will be 35.

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A kicker made 10 of his last 12 field goals.

Predict the number of his next 42 field goals the kicker will not make will be

Let x be the number of his next 42 field goals the kicker will not make.

Then we have

x / 10 ≠ 42 / 12

x ≠ 35

Two companies working together can clear a parcel of land in 27 hours. Working alone, it would take Company a 2 hours longer to

algol13

Answer:

53 hours

Step-by-step explanation:

If A is the time it takes Company A, and B is the time it takes Company B, then:

1/27 = 1/A + 1/B

A = B + 2

Substitute and solve:

1/27 = 1/(B + 2) + 1/B

1/27 = (B + B + 2) / (B (B + 2))

1/27 = (2B + 2) / (B² + 2B)

27 (2B + 2) = B² + 2B

54B + 54 = B² + 2B

0 = B² − 52B − 54

B = [ -(-52) ± √((-52)² − 4(1)(-54)) ] / 2(1)

B = (52 ± √2920) / 2

B ≈ 53.0

It would take Company B approximately 53 hours.

Mr. and Mrs. Romero are expecting triplets. Suppose the chance of each child being a boy is 50% and of being a girl is 50%. Find

Papessa [141]

Answer:

1) $\text{P(at least one boy and one girl)}=\frac{3}{4}$

2) $\text{P(at least one boy and one girl)}=\frac{3}{8}$

3) $\text{P(at least two girls)}=\frac{1}{2}$

Step-by-step explanation:

Given : Mr. and Mrs. Romero are expecting triplets. Suppose the chance of each child being a boy is 50% and of being a girl is 50%.

To Find : The probability of each event.

1) P(at least one boy and one girl)

2) P(two boys and one girl)

3) P(at least two girls)

Solution :

Let's represent a boy with B and a girl with G

Mr. and Mrs. Romero are expecting triplets.

The possibility of having triplet is

BBB, BBG, BGB, BGG, GBB, GBG, GGB, GGG

Total outcome = 8

$\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total number of outcome}}$

1) P(at least one boy and one girl)

Favorable outcome = BBG, BGB, BGG, GBB, GBG, GGB=6

$\text{P(at least one boy and one girl)}=\frac{6}{8}$

$\text{P(at least one boy and one girl)}=\frac{3}{4}$

2) P(at least one boy and one girl)

Favorable outcome = BBG, BGB, GBB=3

$\text{P(at least one boy and one girl)}=\frac{3}{8}$

3) P(at least two girls)

Favorable outcome = BGG, GBG, GGB, GGG=4

$\text{P(at least two girls)}=\frac{4}{8}$

$\text{P(at least two girls)}=\frac{1}{2}$
