9514 1404 393

Answer:

  x1 = 1/2 + 1/2t

  x2 = 4 -2t

  x3 = t

Step-by-step explanation:

Your answer is correct as far as it goes. The values of x1 and x2 also need to be expressed in terms of t.

  x1 = 1/2 + 1/2t

  x2 = 4 -2t

  x3 = t

Which is greater or equal 7/10 or 9/100
Pavlova-9 [17]

9/100 is less because if we multiply 7/10 by 10 (to get an equivalent fraction with a denominator the same as the other fraction [100]) we get 70/100, which is way more than 9/100.

So, 7/10 is greater than 9/100

Hope this helps!

Please help me on this
avanturin [10]

Answer:

1. 8

2. 11

3. 14

4. 17

Step-by-step explanation:

When there is a number next to a number inside parenthesis, it means you multiply those together. Don't forget to use PEMDAS either. So you first multiply 3(and whatever number is inside) and then add 5. Hope this helped :)

<h3>What is geometrical figure?</h3>

Geometrical shapes are the shapes that depict the shapes of various items. Various figures have two dimensions, while others have three. Only the x and y axes are used for two-dimensional figures, whereas the x, y, and z axes are used for three-dimensional shapes.

<h3>According to the given information:</h3>

Given,

Area = 11000m²

Radius = .10m/h

We know the area of the circle:

Area = πr²

The relation between parameter:

Area = πr²

11000 = 3.14 * (0.10t)²

Dividing both side by 3.14

11000/3.14 = (3.14 * (0.10t)²)/3.14

by solving this we get:

(.10t)² = 3503.184

.10t = 59.187

dividing both side by 0.10

t  = 59.187/.10

t =  591.877

t = 592

hours did it take for oil to cover the area  = 592
