volume of sphere = 4πr³/3 = 36π

r³ = 27

r = 3 ft³

surface area of sphere = 4πr² = 36π ft²

Answer:

-2

Step-by-step explanation:

(x³+5x²-2-2x-24) by (x-2)

x-2 = 0

x=2.

2³ + 5(2)² - 2 - 2(2) - 24

= 8 + 20 - 2 - 4 - 24

= 28 - 30

= -2.

Step-by-step explanation:

The quotient of 3 and -30 is a rational number. The correct answer would be an option (B).

A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.

The quotient of 3 and -30 is:

3 ÷ (-30) = -0.1

Therefore, the quotient is a rational number. Option B is correct.

A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero. In this case, -0.1 can be expressed as the ratio of the integer -1 and the integer 10, where the denominator 10 is not zero.

Note that the quotient is negative because we are dividing a positive number (3) by a negative number (-30).

Answer:

Given:

The radius of a wheel =r=35 cm=0.35 cm.

The speed it must keep =s=66 km/h=

60

66×1000

m/min=1100 m/min

To find out:

The number of revolution =n, it makes per minute to maintain that speed.

Solution:

The circumference =C of the wheel =2πr=2×

7

22

×0.35 m=2.2 m=C

The distance the wheel covers in 1 min=d=1100 m.

Now the distance =d covered by a wheel in one revolution = the circumference of the wheel.

∴ Here the number of revolution =n=

C

d

=

2.2

1100

=500.

Answer:

1899.7 in^3.

Step-by-step explanation:

Radius = 1/2 diameter

= 22 * 1/2 = 11.

Volume = 1/3 pi r^2 h,  so

= 1/3 * 3.14 *1 1^2 *1 5

= 1899.7 in^3.

Step-by-step explanation:

Charles have 3533.10 quetzals.

It is the conversion of one unit to another unit with its standard conversion.

Examples:

1 hour = 60 minutes

1 minute = 60 seconds

1 km = 1000 m

We have,

Charles allocated amount for spending = $415.

The exchange rate from US dollars to Guatemalan quetzals.

= 1 : 8.5135

This means,

$1 = 8.5135 quetzals

Now,

$1 = 8.5135 quetzals

Multiplying 415 on both sides.

$415 = 415 x 8.5135

$415 = 3533.1025 quetzals

Rounding to two decimal places.

$415 = 3533.10 quetzals.

Thus,

Charles has 3533.10 quetzals.

Answer:

y=x+1

Step-by-step explanation:

First find the slope by subtracting the y values from both points and dividing it by the subtraction of the x values from both points:

-4--2/ -3--1= -2/-2= 1

so the slope is 1

Now find the y-intercept by plugging in the x and y from one of the points into the equation y=x+b

-3=-4+b

1=b

now plug the slope and y intercept in:

y=x+1
