Find the volume of a right circular cone that has a height of 19.5 m and a base with a
radius of 3.9 m. Round your answer to the nearest tenth of a cubic meter.

Step-by-step explanation:

2(heads) + 2(goats) = 140

Heads are given, so we get:

2(52) + 2(goats) = 140

104 + 2(goats) = 140

2(goats) = 36

goats = 18

Since we know the number of goats, we know the number of chickens.

34Chickens and 18 goats.

The diver will be in the air for approximately 0.78 seconds to the nearest hundredth of a second.

The equation that represents the height of the diver above the surface of the pool is given by:

h(t) = -16t² + 6t + 33

where t is the time in seconds and h(t) is the height of the diver above the surface of the pool in feet.

The diver will be in the air until he reaches the surface of the pool, which means that his height will be 0. Therefore, we can set h(t) equal to 0 and solve for t:

-16t² + 6t + 33 = 0

We can use the quadratic formula to solve for t:

t = (-b ± sqrt(b² - 4ac)) / 2a

where a = -16, b = 6, and c = 33.

Plugging in these values, we get:

t = (-6 ± sqrt(6² - 4(-16)(33))) / 2(-16)

t = (-6 ± sqrt(36 + 2112)) / (-32)

t = (-6 ± sqrt(2148)) / (-32)

Simplifying:

t = (-6 ± 46.34) / (-32)

So we have two solutions:

t = (-6 + 46.34) / (-32) ≈ 0.78 seconds

t = (-6 - 46.34) / (-32) ≈ 2.64 seconds

Since the diver cannot be in the air for a negative amount of time, we reject the second solution.

Answer:

1. Volume measured in Cubic units (to the third power), Only 3-D objects have volume.

2. Parallel lines have the same slope and will never intersect. The slope of perpendicular lines are the negative reciprocals of each other, they will intersect a 90 degrees

3. Secant is 1/cosX (1 over cosine of x), tangent is sinX/cosX(sine of x over cosine of x)

Answer:

each apple is £ 1.80

Step-by-step explanation:

i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.

Then i took the remaining money and divided it by 2 to get how much each apple costs.

Answer:

1.80

Step-by-step explanation:

1) Price of Pears

[tex]1.30 * 7 = 9.10[/tex]          formating: 1.30*7 = 9.10

2) Price of Apples

[tex]12.70 - 9.10 = 3.60[/tex]          formating: 12.70-9.10 = 3.60

3) Price of Apples/Kg

[tex]\frac{3.60}{2} = 1.80[/tex]          formating: 3.60/2 = 1.80

Answer:

Area of square is 625 cm².

Explanation:

Side (length) = 25 cm

As we know, all the sides of the square are equal.

Further,

Area of the square = (side) ²

Area = ( 25 )²

Area = 625 cm²

Therefore, area of the square is 625 cm².

Answer:

a)0.135%

b) 36.944%

c) 95.209%

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 2.25 hours

σ is the population standard deviation = 0.75 hours

a) What portion of adults are in front of a computer for less than 0 hours a day, outside of work?

x < 0 hours

Hence,

z = 0 - 2.25/0.75

= -3

Probability value from Z-Table:

P(x<0) = 0.0013499

Converting to Percentage

= 0.0013499 × 100

= 0.13499%

= 0.135%

b) Medical professions recommend spending no more than 2 hours in front of a computer each day. What portion of the population is on their computer more than the recommended amount?

No more than 2 hours

x ≤ 2 hours

x < 2 hours

Hence,

z = 2 - 2.25/0.75

= -0.33333

Probability value from Z-Table:

P(x≤ 2) = 0.36944

Converting to Percentage

= 0.36944 × 100

= 36.944%

c)What portion of adults spend between 1 and 5 hours a day in front of a compute reach day, outside of work?

For x = 1 hour

z = 1 - 2.25/0.75

= -1.66667

P-value from Z-Table:

P(x= 1) = 0.04779

z = 5 - 2.25/0.75

= 3.66667

P-value from Z-Table:

P(x = 5) = 0.99988

Hence,

0.99988 - 0.04779

= 0.95209

Converting to Percentage

= 0.95209 × 100

= 95.209%
