Elmer has a collection of 300 fossils. Of these, 21 percent are fossilized snail shells.

Answers

Answer 1

Answer: In order to figure out the number of fossilized snail shell, multiply 21% by 300. first change 21% into a decimal, in order to do that, move the percent symbol two spaces to the left, and replace the "%" symbol to a decimal. 0.21 X 300= 63
so 21% of 300 is 63

A shopper thought shoes marked $40 the sales tax is 8% how much the shopper pay in all

Answers

so, if I understand correctly the prize before sales tax is 40 dollars and the sales tax is 8%. how much is this?

$(8)/(100) *40= (8)/(10) *4=(4)/(5) *4= (16)/(5) =3.2$

so the final prize is 40+3.2=43.2

Prime or composite 52

Answers

52 is composite
prime can be divided evenly only by 1, or itself
but 52 can divided by 2,4,13, etc...
hope it helps

If it is prime, it cannot be split in 2 numbers that multiply to equal it. Look at the last number of the number to get a hint first. The last number of 52 is a 2. If you recall, any number that ends ina 2 or 0 can be divided by 2:

52
/ \
2 26

2 13

There the number is fully factored.

(a) The volume of the brick is 650 cubic centimeters (cm³), and the surface area is 490 square centimeters (cm²).

(b) The painter should base paint quantity on surface area (490 cm²).

(a) To find the volume and surface area of the rectangular prism-shaped brick, we can use the following formulas:

Volume (V) = Length × Width × Height

Surface Area (SA) = 2(LW + LH + WH)

Given the dimensions of the brick:

Length (L) = 13 cm

Width (W) = 5 cm

Height (H) = 10 cm

Now, let's calculate:

Volume (V) = 13 cm × 5 cm × 10 cm = 650 cubic centimeters (cm³)

Surface Area (SA) = 2(13 cm × 5 cm + 13 cm × 10 cm + 5 cm × 10 cm) = 2(65 cm² + 130 cm² + 50 cm²) = 2(245 cm²) = 490 square centimeters (cm²)

So, the volume of the brick is 650 cm³, and the surface area is 490 cm².

(b) The painter should consider the surface area to determine how much paint to buy. Surface area represents the total area that needs to be covered with paint. In this case, it's 490 cm². Buying paint based on the surface area ensures that there's enough paint to cover the entire exterior of the brick.

(c) To find the amount of concrete needed to make the brick, we would use the measure of volume (V). Concrete is typically sold and purchased by volume, and in this case, the volume of the brick is 650 cm³. So, to determine the amount of concrete required, we would use the volume measurement (650 cm³).
