Hey there! I’m happy to help!

The surface area is basically the area of the surface of the shape. So, if you have a cube, it’s the area of all of the surface of the cube, not anything inside.

We see that we have a net of this square pyramid. If we fold it up, the square and four triangles will make up the surface of the 3D shape we see. So, we need to find the area of all of these shapes.

SQUARE
To find the area of a square, you multiply one of the sides by itself (all the sides are the same)

10(10)=100

TRIANGLES
To find the area of a triangle, you take the base and multiply the height and then divide it by two.

10(12)=120
120/2=60
Since we have four triangles, we multiply it by four.
60(4)=240

Finally, we add this all up.

240+100=340

Therefore, the answer is 340 square inches.

I hope that this helps! Have a wonderful day!

serious [3.7K]

Answer:

The next number selected should be between 2 and 3 .

Step-by-step explanation:

x. x    f(x)             g(x)

0        10               17

1           11              19

2          14              21

3          19              23

4         26             25

3.5      22.25        24

<u>2.5      16.25         22</u>

1.5       12.25        20

0.5       10.25       18

We see the pattern that it is increasing with only a unit. The last given data is mid of the last two values that is 3 and 4.

So the next value would be the mid of the next last two values that is 2 and 3 and will be 2.5

Now it is moving in the reverse direction in the same pattern  with a difference of a unit.

A patient was supposed to take 560 mg of medicine but only tool 420 mg.What percent of the medicine did the patient take?
Stolb23 [73]
75% I think.

because if you do 560 - 420 you get 140.

140 / 560 x 100 = 25

which means there is a 25% decrease, so they took 75%.
