Maggie has 4 3/5 of icing to decorate cakes for a bake sale. Each container will cover 20 1/4 in2. How many square inches will i
ExtremeBDS [4]

Answer:

93\frac{3}{20} \ square \ inches.

Step-by-step explanation:

Given:

Maggie has 4 3/5 container of icing to decorate cakes for a bake sale.

Each container will cover 20 1/4 square inches.

Question asked:

How many square inches will it cover if she uses all of her icing ?

Solution:

Total number of container Maggie has = 4\frac{3}{5}

Each container will cover = 20\frac{1}{4} square inches.

Now, we can find easily that how many square inches it will cover by using all of her icing by unitary method:

Each container will cover = 20\frac{1}{4}

4\frac{3}{5} container will cover = 20\frac{1}{4}\times4\frac{3}{5} =\frac{20\times4+1}{4} \times\frac{5\times4+3}{5} \

                                                        =\frac{81}{4} \times\frac{23}{5} =\frac{1863}{20} =93\frac{3}{20}\ square\ inches

Thus,  it will cover 93\frac{3}{20} \ square \ inches ,if she uses all of her icing.

Which of the following is equal to the average of (x+2)^2 and (x-2)^2
Digiron [165]

C

expand factors, sum like terms and divide by 2

(x + 2)² + (x - 2)² = x² + 4x + 4 + x² - 4x + 4 = 2x² + 8

\frac{1}{2}(2x² + 8 ) = x² + 4 → C
