Answer:

2.8

Step-by-step explanation:

This is the same as:

0.4+0.4+0.4+0.4+0.4+0.4+0.4

If we were to change the question to:

4+4+4+4+4+4+4=28

That would be 10x this question's answer, Therefore you divide 28 by 10 to give you 2.8

If the surface area of the box of cereal is 272 inches squared, find the length of the box.
LekaFEV [45]

Answer:

x= 8 inches

Step-by-step explanation:

you left out the other lengths but since i had this same question once, the other lengths are 12 and 2-

dimensions of the box:

12 in x 2 in x ?

=272 square inches

and we know that there are 6 faces

area=  2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)

area = 272 sq. in.  = 48 + 4x + 24x

272 = 48 + 28x

272 - 48 = 28x

224 = 28x

x = 8 inches

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

AVprozaik [17]

Answer:

11.362 sq km

1136.2 hectares

Step-by-step explanation:

Given that:

The farm is in the shape of a rectangle.

Dimensions of the rectangular shaped land = 2.6 km by 4.37 km

To find:

Area of land bought in square km and in hectares.

Solution:

First of all, let us have a look at the formula for area of a rectangular shape figure.

Area = Length \times Width

Here,

Length = 2.6 km

Width = 4.37 km

So, Area = 2.6 \times 4.37 = 11.362\ sq\ km

To convert square kilometers to hectares, we can use the following conversion formula:

1 sq km = 100 hectares

11.362 km = 100 \times 11.362 = <em>1136.2 hectares</em>

Sammy served food to a group at a restaurant. The total cost of the food was $62.00. The sales tax is 6% of the cost of food. Th
alex41 [277]
Total cost = 62 + (6% of 62) + (20% of 62)

-  Find 6% of 62:
1% = 62 / 100 = 0.62
0.62 x 6 = 3.72

-  Find 20% of 62:
10% = 6.2
6.2 x 2 = 12.4

Add everything together:
62 + 12.4 + 3.72 = 78.12

The total cost was $78.12
