A wildlife sanctuary has two elephants. One has a weight of 11,028 pounds and the other has a weight of 5 1/2 tons. A platform c
Airida [17]

Answer:

The platform cannot hold both elephants.

Step-by-step explanation:

This problem is solved by conversion of units.

Elephant A weighs 11,028 pounds

Elephant B weighs 5 1/2 = 5.5 tons

The platform can hold 22,000 pounds

To see if the platform holds both elephants, the first step is converting the weigth of Elephant B to pounds.

Each ton has 2000 pounds.

So 5.5 tons have 5.5*2000 = 11000 pounds.

So Elephant B weighs 11000 pounds

Combined weights of Elephants A and B

11,028 + 11,000 = 22,028 > 22,000

The platform cannot hold both elephants.

What is -3(4x+3)+4(6x+1)=43
LenaWriter [7]

-3 (4x + 3) + 4(6x + 1) = 43.

-12x + -9 + 24x + 4 = 43.

Combine like terms:

-12x + 24x = 43 + 9 - 4.

12x = 48.

Divide both sides by 12:

12x / 12 = 48 / 12.

x = 4.

A conical paper cup has a radius of 2 inches. Approximate, to the nearest degree, the angle β so that the cone will have a volum
dezoksy [38]
Volume = area of base *height 

20 = pir^2 *h

20 = 3,14*4*h

h = 20/12,56 = 1,59 rounded 1,6

- using the triangle formed by radius,the height of cup and the slant height of cup so we can writing that

tan ß = h/r so tan ß = 1,6/2 = 0,8

tan ß = 0,8 so ß = arctan 0,8 = 38,6 degrees so 39 degrees 

hope helped
