I believe that they typo meant 300 fossils of which 21% are snail shells.

Since % means per one hundred...

300(21/100)=63

Elmer has 63 fossilized snail shells.

An employee earned $56,700.00 in a year and had $8,788.50 withheld for federal income tax. What federal income tax percent was w
alexandr1967 [171]
So earned 56,700 in a year and had 8,788.5 held back
convert to percent

so find what percent was withhelald which is (amount held back)/(total taken from)
so it would be 8,788.5/56,700=0.155/1
percent means parts out of 100 or x/100=x% so convert the bottom number ot 100 by mulitplyint the whole fraction by 1 or 100/100 so
0.155/1 times 100/100=15.5/100=15.5%
the answer is 15.5%

In a department qstore, a $40 dress is marked, save 25%" what is the discount?
PSYCHO15rus [73]
To find the discount of an item you put the rate which is 25% over 100 and move the decimal point to the right this would leave you with 0.25.You then times $40 by 0.25 which leaves you with $10 so $10 is your discount.

To find the sales price of the dress you subtract the discounted price from the original price so it would be $40-$10 which is $30 so your sales price is $30.

What is the surface area of the figure shown?
Shalnov [3]

Answer:

The surface area of the figure = 962 ft²

Step-by-step explanation:

The rectangle dimensions and its area given below

Dimensions       Number         Area

12 x 7                2                   12 x 7 x 2 = 168

16 x 7                1                    16 x 7 = 112

12 x (16 + 5)     1                    12 x 21 = 252

16 x 12              1                    16 x 12 = 192

16 x 13              1                     16 x 13 = 208

Triangle dimensions

Dimensions           Number         Area

b = 12  & h = 5       2                bh/2 = (12*5)/2  = 30

To find total area

Total area = 168 + 112 + 252 + 192 + 208 + 30 = 962 ft²
