Answer:

100 seconds

Step-by-step explanation:

I've seen this question before. I know you didn't mean to put 858585.

The real question is "Kong took 15% percent fewer seconds than Nolan took to complete his multiplication timed test. Kong took 85 seconds. How many seconds did Nolan take?"

Now let's work!

Kong took 15% fewer seconds than Nolan took.

So Kong took 100%−15%=85%

Whatever Nolan's total was, Kong had 85% of that.

We know Kong took 85 seconds. 85% of Nolan's total is 85 seconds.

=100 seconds. 85%=15 seconds

Which means that Nolan took 100 seconds.

Glad I was able to help!!

Dimensions of a Box A large plywood box has a volume of . Its length is ft greater than its height, and its width is ft less tha

cupoosta [38]

Answer:

Few things are missing, they are volume of the box is 180 feet cube. Length is 9 feet greater than its height, and weight is 4 feet less than its height.

Step-by-step explanation:

Given, the volume of the box, V = 180 feet cube

Let the height of the box, h = x feet

Therefore, length is, l = ( 9+x ) feet

And width is, b = ( x-4) feet

so volume of the box is

V = l x b x h

$180= (x+9) \times (x-4) \times (x)$

$x^3 +5x^2-36x -180 =0$

Factorizing we get

(x+5)(x-6)(x+6)=0

Therefore,

x = -5, -6, 6

Now since the height of the box cannot be negative, so taking the positive value of x, we get

Height of the box, h = x = 6 feet

Length , l = ( 9+x ) = 9+6 = 15 feet

Width , b = ( x-4) = 6-4 = 2 feet

What percent of 33 is 96

Nataly_w [17]

<span>96/x=100/33
(96/x)*x=(100/33)*x - we multiply both sides of the equation by x
96=3.0303030303*x - we divide both sides of the equation by (3.0303030303) to get x
96/3.0303030303=x
31.68=x
x=31.68

now we have:
33% of 96=31.68
