The base of a triangle is twice the height of the triangle.

Mathematics
1 answer:
Andreas93 [3]2 years ago
6 0

Answer:

<h3>4cm</h3>

Step-by-step explanation:

area =  \frac{1}{2} \times base \times height \\ 16 {cm}^{2}  =  \frac{1}{2}  \times 2x \times x \\ 16 {cm}^{2}   =  \frac{2 {x}^{2} }{2}  \\ \\ 16 {cm}^{2}  \times 2 = 2 {x}^{2} \\ 32 {cm}^{2}  = 2 {x}^{2}  \\  \frac{32 {cm}^{2} }{2}  =  {x}^{2}  \\ 16 {cm}^{2}  =  {x}^{2}  \\  \sqrt{16 {cm}^{2} }  =  \sqrt{ {x}^{2} }  \\ 4cm = x \\

What is 1 /7 as a decimal rounded to 3 decimal places?
Nostrana [21]

Answer:

0.143

Step-by-step explanation:

You need to convert 1/7 to have a denominator of either 100 or 10. We can do 100.

1/7 = ?/100

then you need to divide 100/7 to find the scale factor which in this case is 14.286

then you can insert it into the equation

1/7 = 1 * 14.286/100

you end up with

14.286/100

then you can dived the two

0.14286 is what you end up with

but since it says rounded to the 3rd decimal place you go to the 3rd which is 2.

To round it you look at the 4th number which is 8.

<em>5 and above give it a shove up</em>

So now its 0.143

Hope this helped :)

The linear relationship represented by the table has an initial value of 88 and a rate of change -6. Complete the table.
Nimfa-mama [501]
(2,88)
(6,64)
(9,46)
(15,10)
first find y=mx+b
88=-6(2)+b
b=100
y=-6x+100
then plug for y and solve for x or vise versa.

Slope (y2-y1)/(x2-x1)
(0-4)/(-5-5) = -4/-10 = 2/5
Y = 2/5x + b
Plug in any point
4 = 2/5(5) + b
4 = 2 + b, b= 2
Final equation: y = 2/5x + 2
