Find the surface area of the figure below.
PSYCHO15rus [73]
The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,

                       A = bh / 2
where A is area, b is base and h is the height. 

Substituting the known values,

                      A = (4 inch)(9 inch) / 2 = 18 in²

Multiplying this area by 4 will give us an answer of 72 in².


Then, we also calculate for the area of the square base.
                      A = s²
where s is the measure of each side of the square.

                       A = (4 in)² = 16 in²

Finally, we add up the calculated areas.
                  surface area = 72 in² + 16 in²
                      <em>surface area = 88 in²</em>

Hence, the surface area of the figure is equal to 88 in².

Alicia wants to bake a cake with ⁹/10 grams of flour.However,she only has ⅓ grams of flour she needs.How much does she have?
natali 33 [55]

Answer:

We know that:

She needs 9/10 grams of flour for the cake (this quantity does not make a lot of sense, maybe is written incorrectly, but is the only info we have, so let's solve the problem with this)

She only has 1/3 of the amount she needs.

How much flour does she have?

Well, she needs 9/10 grams, and she has one-third of that.

Then she has (1/3) times (9/10) grams, this is:

F = (1/3)*(9/10) grams

F = (1*9)/(3*10) grams

F = 9/30 grams

That is the amount of flour that she has.
