Hello from MrBillDoesMath!

Answer:

Discussion:

Total Surface area = area of pyramid base + 4 ( area of triangular face)

In our case this becomes

4*4 + 4( (1/2) (4)(7) ) =

= 16 + (2)(4)(7)

= 16 + 56

= 72

which is the first choice.

Note: the area of a triangular face was computed using (1/2) b h, which in our case is

(1/2) (4) (7)

Thank you,

Margaret’s bottle of shampoo is 7/8 full. She uses 1/3 of the shampoo in the bottle to wash the dog. Estimate what fraction of s

AleksandrR [38]

Fraction of shampoo left = $\frac{13}{24}$

Solution:

Given fraction of full shampoo $=\frac{7}{8}$ .

Fraction of shampoo Margaret used $=\frac{1}{3}$

Fraction of shampoo left = Full shampoo – fraction of shampoo used

$=\frac{7}{8}-\frac{1}{3}$

To make the denominators same do cross multiplication.

$=\frac{7\times3}{8\times3}-\frac{1\times8}{3\times8}$

$=\frac{21}{24}-\frac{8}{24}$

$=\frac{21-8}{24}$

$=\frac{13}{24}$

Hence $\frac{13}{24}$ of the shampoo bottle is left.
