Maurinko [17]

Answer:

a)16.32 rounded to the nearest whole number is 16 feet per second? True

b) 16.32 rounded to the nearest tenth is 16.3.? True

c) 16.32 rounded to the nearest hundredth is 16.33. ? False

Step-by-step explanation:

Select True or False for each statement.

a) 16.32 rounded to the nearest whole number is 16 feet per second. ?

16.32 to nearest whole number = 16 feet per second. This statement above is true.

b) 16.32 rounded to the nearest tenth is 16.3. ?

The number in the tenth position is 3, the number after it is 2.

Hence, 16.32 to the nearest tenth = 16.3

Hence, the above statement is true.

c) 16.32 rounded to the nearest hundredth is 16.33. ?

The number in the hundredth position is 2. There is no number after 2.

Hence,

16.32 to the nearest hundredth is 16.32

Hence, 16.32 rounded to the nearest hundredth is 16.33 is a false statement.

Elza [17]

Answer:

Step-by-step explanation:

Given: $\frac{1}{2} ? \frac{1}{3}$

Want: Which fraction is larger?

To identify the size of a fraction, converting it into a fraction is easier

$\frac{1}{2}$ = 0.5

$\frac{1}{3}$ = 0.33

where 0.5 is greater than 0.33

Choices:

< is less than symbol

> is greater than symbol

= is equal to

$\frac{1}{2} > \frac{1}{3}$

10 A solid metallic cylinder of radius 14 cm and

vodomira [7]

Answer:

72 spheres are formed

Step-by-step explanation:

We start by calculating the volume of the metallic cylinder

Mathematically, we have this as;

V = pi * r^2 * h

V = pi * 21 * 14^2

V = 4116 π cm^3

The volume of each small sphere is;

V = 4/3 * pi * r^3

= 4/3 * π * 7/2^3 = 57.167 π cm^3

To get the number of small spheres, we simply divide the volumes

That will be 4116 pi / 57.167 pi = 72

It's just a simple equation but the transversal has me stuck

alexgriva [62]

Answer:

x = 22

Step-by-step explanation:

∠VSR and ∠SRU are same- side interior angles and are supplementary, thus

5x + 4 + 44 + x = 180, that is

6x + 48 = 180 ( subtract 48 from both sides )

6x = 132 ( divide both sides by 6 )

x = 22
