Answer:

4x+24 ft.

Step-by-step explanation:

Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.

Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.

Add these two together: 2x+4 + 2x+20 = 4x+24. Don't forget to add units: 4x+24 ft.

2. Brian is filling a conic container with water. He has the container half full. The radius of the container is 5 inches and th
MakcuM [25]

Answer:

current volume of the water = 785.714 in²

Height of new container = 10 inches

Step-by-step explanation:

Radius of the container = 5 inches

Height of the container = 20 inches

Volume of the container = πR²H = (22/7) × 5² × 20 = 1571.428571428 in²

Since the container is half filled with water, volume of the water = 1571.428571428 ÷ 2 = 785.714 in²

b. Volume of cylinder = πR²H = volume of water from first container = 785.714 in²

Hence 785.714 = (22/7) × 5² × H

H = (785.714) ÷ [(22/7) × 25] = 10 inches

Height of new container = 10 inches

What is Yx6 for Y=2/3
Karolina [17]
Well, it would be 2/3 x 6, which you could 2/3 x 6/1 and then it would be 12/3 which would equal 4. This can also be proven through inspection, since 2/3's of 6 is 4 because 1/3 of 6 is 2.

Please help it's urgent ​
ira [324]

Answer:

no solutions exist

Step-by-step explanation:

You can rewrite the denominator as:

-2(2x-6) so the equation becomes:

-\frac12 \cdot \frac{2x-6}{2x-6} > 0

from which you can see that not only should x ≠ 3, but for all values of x≠3 the equation is false.

Feliz [49]

Answer:

15 goals out of 50 penalty kicks was scored by brock

Step-by-step explanation:

If Brock shoots 50 penalty kicks and the probability that he scores a penalty kick is 3/10, the number of goal brock is expected to make can be expressed as:

Number of goals scored = probability value * total penalty kicks taken

Number of goals scored = \frac{3}{10}*50

Number of goals scored = 15 goals
