Find the surface area of a cuboid whose sides are 3cm by 6cm by 10cm

Brilliant_brown [7]

Answer:

216 cm²

Step-by-step explanation:

Use the formula for the surface area of a cuboid.

SA = 2lw + 2lh + 2hw

2(6)(3) + 2(6)(10) + 2(10)(3)

36 + 120 + 60

= 216

The surface area of the cuboid is 216 cm².

Isabella ran the 100-meter dash five times. The time it took her to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.

Stells [14]

Given:

Number of 100-meter races = 5

The time it took Isabella to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.08, and 12.087.

To find:

The decimals in order from greatest to least.

Solution:

The time it took Isabella to complete each race, in seconds, was shown below:

12.7, 12.807, 12.78, 12.08, 12.087

We need to arrange this data in descending order.

In all 5 numbers the digits before decimals are same. On comparing the digits on the tenth place and hundredth place, we get

12.807 > 12.78 > 12.7 > 12.087 > 12. 08

Therefore, the required order of given data is 12.807, 12.78, 12.7, 12.087, 12. 08.

{5x−y=−21 What is the solution of the system?

Montano1993 [528]

Answer:

Step-by-step explanation:

5x - y = -21

y = 5x + 21

Substituting into:

x + y = -3

x + 5x + 21 = -3

6x = -24

x = -4

y = 5(-4) + 21

y = 1

Solution: (-4,1)
