candice is going to replace the top of a table with a new piece of wood. How many square feet of wood would she purchase? 8ft. ,

lukranit [14]

Answer:

She needs to purchase 50 square feet of wood .

Step-by-step explanation:

we can find the number of square feet of wood needed to purchase by finding the area of the table

The area of the table = area of the triangle + area of the rectangle

Area of the triangle:

Area of the triangle = $\frac{1}{2}(base \times height)$

On substituting the values from the attached figure , we get

Area of the triangle = $\frac{1}{2}(4\times 5)$

Area of the triangle = $\frac{20}{2}$

Area of the triangle = 10 square feet

Area of the rectangle:

Area of the rectangle = Length X Breadth

On substituting the values from the attached figure , we get

Area of the triangle = $5 \times 8$

Area of the triangle = 40 square feet

Thus the area of the table = 10 + 40 = 50 square feet

A pair of boots is 30dollars more than a pair of sandals. A pair of sandals cost s dollars each. Emily purchased 2 pairs of boot

babunello [35]

Answer: The expression representing the amount of money spent is $5x+60$ by Emily.

Step-by-step explanation:

Since we have given that

Let the cost price of per pair of sandals be 's'

Let the cost price of per pair of boots be 's+30'.

Number of pairs of boots = 2

Number of pairs of sandals = 3

Total cost would be

$2(s+30)+3s\\\\=2s+60+3s\\\\=5s+60$

Hence, the expression representing the amount of money spent is $5x+60$ by Emily.
