The mode is whatever number that repeats itself the most, which would be 3 in this case. To find the range you would find the difference between the highest number and the lowest number. The highest number is 8 and the lowest is 1 so 8-1=7. The range is 7.

Each container has a base of 4 1/4 yds by 1 2/3 yds. What is the area covered by all the containers?

Answer:

See Explanation

Step-by-step explanation:

Given

Base Dimension

$Length = 4\frac{1}{4}yd$

$Width = 1\frac{2}{3}yd$

Required

The base area of all containers

First, calculate the base area of 1 container.

This is calculated as:

$Area = Length * Width$

$Area = 4\frac{1}{4}yd * 1\frac{2}{3}yd$

Express as improper fraction

$Area = \frac{17}{4}yd * \frac{5}{3}yd$

So, we have:

$Area = \frac{17*5}{4*3}yd^2$

$Area = \frac{85}{12}yd^2$

The number of containers is not given. So, I will use 'n' as the number of containers.

So, we have:

$Total = n * Area$

$Total= n * \frac{85}{12}yd^2$

--------------------------------------------------------------------------------------------

Assume n is 3 (i.e. 3 containers)

The total area is:

$Total= 3 * \frac{85}{12}yd^2$

$Total= \frac{85}{4}yd^2$

$Total= 21\frac{1}{4}yd^2$

maksim [4K]

Answer:

312

Step-by-step explanation:

T.S.A : ( 2 × L × w ) + ( 2 × h × w ) + ( 2 × L × h ) = Area

9 - 3 = 6 - 3 = 3

( 2 × 12 × 3 ) + ( 2 × 8 × 3 ) + ( 2 × 12 × 8 ) = Area

72 + 48 + 192 = 312

When a force of 30 N acts on a certain object the acceleration of the object is 5 m/s^2 if the acceleration becomes is 8m/s ^2 w

Varvara68 [4.7K]

Answer:

48 N

Step-by-step explanation:

The equation for force is

F = m * a

where F is force, m is mass, and a is acceleration

30N = m * 5m/s²

m = 6 kg

F = 6kg * 8m/s² = 48 N
