There are 64 animals at the zoo. ⅜ of the animals are birds. How many birds are at the zoo?
xxTIMURxx [149]

Answer:

24

Step-by-step explanation:

3/8 of the 64 total animals at the zoo are birds.

To solve, this, multiply 3/8 and 64

3/8*64=24

Another way to solve would be to make a proportion

3/8=x/64

Multiply both sides by 64 to get x by itself

64(3/8)=(x/64)64

24=x

So, 24 out of the 64 animals are birds

First of all, x =-1 (y don’t change) so first 2 answer is out.
Now mirror to x-1 >>>
A(0,-1)
0 >> -1 is left one step so -1 left one step is -2
A(0,-1) >> A’(-2,-1)

A(-5,0)
-5 >> -1 is right 4 step so -1 right 4 step is 3
A’(3,0)

Help please!
alexdok [17]

Answer:

The answer is 20 meters squared

base area = side^2 = 2^2 = 4 m^2

base perimeter = (2 x 4) = 8 m

lateral surface = (base perimeter x slant height)/2 = (8 x 4)/2 = 16 m^2

surface area = (base area + lateral surface) = (4 + 16)= 20m^2

Solve each of the following equations for xx using the same technique as was used in the Opening Exercise.
devlian [24]

Answer:

The solve of this equation is X = 4,06

Step-by-step explanation:

To solve this formula:

2 ( X² - 16) = 1

You must use the distributive law of multiplication, thus:

2X² - (16×2) = 1

2X² - 32 = 1

2X² = 1 + 32

X² = 33/2

X² = 16,5

X = √16,5

X ≈ 4,06

Thus, the solution of this equation is:

<em>X ≈ 4,06</em>

<em></em>

I hope it helps!
