Answer:
Step-by-step explanation:
The system of equations are expressed as
2x + 17y = −3 - - - - - - - - - 1
5x + 4y = 9 - - - - - - - - - - 2
In order to eliminate y, you will need to multiply equation 1 by 4 and equation 2 by 17. This would make them to have the same value of 68y.
You might choose to eliminate x instead. To do this, you will need to multiply equation 1 by 5 and equation 2 by 2. This would make them to have the same value of 10x.
Answer:
The angles are : 30° , 60° , 90°
Step-by-step explanation:
Sum of angles in a triangle = 180°
Given: the angles are in the ratio = 1 : 2 : 3
Sum of the ratio = 6
Therefore , the angles are
In order to answer this, it would be useful to calculate the area of the cardboard and the circles. We do as follows:
Total area of cardboard = <span> 8.0 in. x 11.0 in = 88 in^2
Area of one circle = pi(r^2) = pi(0.5)^2 = 0.7854 in^2
Number of full circles = 88 / 0.7854 = 112.0451
Therefore, there will be 112 number of full circles. The percentage of waste is equal to:
% waste = (88 - 0.7854(112) / 88) x 100= 0.04%</span>
<h3>s³=l,b,h</h3><h3>so,</h3><h3>s³=125</h3>
![s = \sqrt[3]{125}](https://tex.z-dn.net/?f=s%20%3D%20%20%5Csqrt%5B3%5D%7B125%7D%20)
<h3>s=5 and height =5 cubes</h3><h3>hope it helps :-)</h3>
The answer is 36. The ruler and tree are measured at the same time, so the scaling is the same. You divide 12 by 8, which is 1.5. Since the height of the pine tree is what you are trying to find, you must multiply 24(the length of the shadow) times 1.5, which is how you get 36. :)
