3/28 of the animals are birds. 4/15 are birds of prey. What fraction of the animals are birds of prey.

Answers

Answer 1

Answer: let's call animals "a", and birds "b", birds of prey, "p"

so, b= $(3)/(28) a$

and p= $(4)/(15) b$
what;s the relation of p to a?

we substitude b into the last one:

and p= $(4)/(15)* (3)/(28) a$
so:
p= $(4*3)/(15*28) a$

p= $(4*1)/(5*28) a$

p= $(1*1)/(5*7) a$

p= $(1*1)/(35) a$

which is the answer!

Answer 2

Answer:

Final answer:

To find the fraction of animals that are birds of prey, multiply the fraction of animals that are birds, 3/28, by the fraction of those birds that are birds of prey, 4/15, giving (3*4)/(28*15) = 12/420. This simplifies to 1/35. Hence, 1/35 of the animals are birds of prey.

Explanation:

The question is asking for the fraction of animals that are birds of prey. From the problem, we are given that 3/28 of the animals are birds and 4/15 of these birds are birds of prey. To find the fraction of animals that are birds of prey, we need to multiply these two fractions: (3/28) * (4/15).

The method of multiplying fractions involves multiplying the numerators together and the denominators together. So, in this case, the numerator would be 3 * 4 and the denominator would be 28 * 15.

Therefore, the fraction of birds that are birds of prey is (3*4)/(28*15) = 12/420. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common factor which is 12, yielding to 1/35. Hence, 1/35 of the animals are birds of prey.

Nellie split 8 pieces of candy equally among f friends. Which expression shows how many pieces of candy each friend received?

Answers

8/x because split is the same as divide so she split 8 pieces with x people

Final answer:

The expression 8/f represents how many pieces of candies each of Nellie's friends received when she divided 8 pieces of candy equally among them.

Explanation:

The problem presented involves dividing a certain number of items (candies) evenly among a certain number of people (friends). This situation deals with division, a basic concept in mathematics. If Nellie has 8 pieces of candy and wants to split it equally among f friends, each friend would receive 8/f pieces of candy. This is because division is the process of partitioning a quantity into equal parts, so dividing 8 candies by the number of friends will give the pieces each friend will get.

Find the surface area of a rectangle prism

Answers

surface area
it is 6 rectangles
rectangle area=legnth times width

but yo have legnth width and height
how does we do this?
answer
recognize that the rectanles come in pairs
rectanels that are oposite each other have equal areas
so we have
top=bottom=legnth times width
front face=back face=legnth times height
R side face and L side face=width times height

since there are 2 of each
SA=2(LW)+2(LH)+2(WH)
undistribute 2
SA=2(LW+LH+WH)

tada
(note: L=legnth, W=width, H=height)

and give your answer in square units
