Answer:

x = 6 , y = 3

Step-by-step explanation:

x− 2 y = 0 ⇒ x = 2 y  

Substitute x=2y into 4x-3y=15, we get : 4 ( 2 y ) − 3 y = 15

8 y− 3 y = 15  5 y = 15 ⇒ y = 3  x = 2 y = 2 × 3 = 6

Formula for Volume of sphere= 4/3 πr^2

We have,

r=5cm

Now,

Volume(v)=4/3 πr^2 = 4/3π 5^3= 4/3π 125 = 166.666666667π = 523.598775599

Plans call for the reptile Reserve to be surrounded on all sides by a fence. What is the total length of the fence?
Oduvanchick [21]

Answer:

There are no enough information to determine the length of the fence, assuming we were given the perimeter of the fence, and say, the dimension of the fence, then we can easily find the length.

Perimeter of the fence, P = 2(L + B).. If the fence is a rectangular.

L = (P/2) - B

If the fence is square, P = 4L

L = P/4

I need help assssapp
tekilochka [14]

Your mistake is that 1 pound and 15 ounces <em>does not equal</em> 1.15 pounds. You also did not make everything into the same measurement (you mixed up pounds and ounces). I will make everything into the measurement of <em>ounces</em>, since the numbers do not come out clean if we do pounds.


18 pounds (original) = 288

1 pound 15 ounces = 31 ounces

3 1/8 pound = 50 ounces

4 1/2 pound = 72 ounces


So after cutting out those steaks, Mr. Rand has 288-31-50-72 = 135 ounces. Then, it states that he divides those up into 9 ounce patties:

135/9 = 15 patties


And sells them at 3 for $3.12. There are 5 3's in 15 patties, so it is 5 * $3.12 = Mr Rand receives $15.60 for the patties.
