If x = 1.5, than the length of the straw before it is folded is 21 inches. You can find this in the following steps :

12(1.5)^2 -6 = length

12(2.25) -6 = 

27 -6 =

21 

Your answer is: 21 inches 

Have an amazing day mate!

If the surface area of the box in the diagram is 204.25 square feet, what is the value of ‘x’?
Alexandra [31]

Note: Consider x be the breadth of the box.

Given:

The surface area of the box is 204.25 square feet.

Length of the box = 10 ft

Breadth of the box = x ft

Height of the box = 6.5 ft

To find:

The value of x.

Solution:

The surface area of a cuboid is:

SA=2(lb+bh+hl)

Where, l is length, b is breadth and h is height of the cuboid.

Putting SA=204.25,  l=10,\ b=x,\ h=6.5 in the above formula, we get

204.25=2(10\times x+x\times 6.5+6.5\times 10)

204.25=2(10x+6.5x+65)

204.25=2(16.5x+65)

Using distributive property, we get

204.25=2(16.5x)+2(65)

204.25=33x+130

204.25-130=33x

74.25=33x

Divide both sides by 33.

\dfrac{74.25}{33}=x

2.25=x

Therefore, the correct option is B.

The game has 12 three-minute rounds. If the players stop after two minutes of the twelfth round, for how many minutes did they p
gogolik [260]
First of all we know he is at the 12th round, so 11 rounds of 3 minutes passed, so 11 x 3= 33 minutes passed, but we also know that he passed two minutes of the 12th round so 33+2= 35 minutes.
The player played for 35 minutes.

Answer:

Step-by-step explanation:

50 dollars = ∉34

∉1 = Rs 150

Rs 382800 / 150 Rs per ∉  =  382800/150 ∉

=2552 ∉

50 dollars = ∉34          so 50/34 dollars = ∉

2552 ∉ × 50/34 dollar per ∉ =       in the units the ∉ cancel out

                                                         ∉ × dollar/∉    = dollars

(2552 × 50) / 34    = 3752.94 dollars     <------------------

Here is another way of looking at the answer...........

Rs 382800 × 1∉/150 Rs × 50 dollars/34 ∉ =              note how the units cancel

= 382800 × (1/150) × (50/34)                          Rs × ∉/Rs × dollars/∉

=  3,752.94 dollars                                     leaving only dollars in the numerator
