Answer:
The first answer one is true
Answer:
1/40
219/250
69/16
Step-by-step explanation:
1.
0.025=(025)/(1000)=1/40
2.
0.876=876/1000=219/250
3.
4.3125=43125/10000=1725/400=69/16
Answer:
Equation: 
Step-by-step explanation:
<em>The question is incomplete as the dimension of the phone was not given.</em>
<em>However, the following explanation will guide you</em>
Given

Required
Determine the Height
Volume is calculated as thus;

Substitute 75 for Volume

Divide through by Area

<em>The above represent the equation to solve for Height</em>
<em>To solve for height, we need the dimension of the phone or the area.</em>
Take for instance; the length and width of the phone is 5 by 5 inches;
The height would be:



What is linear equation?
An equation between two variables that gives a straight line when plotted on a graph.
2x + 5xy - 3 = 0
x (2 + 5y) -3 = 0
x ( 2 + 5y ) = 3
2 + 5y = 3 / x
5y = (3/x) - 2
y = ( (3/x) - 2) / 5
According to the graph i don't think it's a linear equation.
