Answer:
17.5
Step-by-step explanation:
I beleive since we are connecting midpoints you divide each side by 2 and add them all up to get the perimeter of the smaller triangle made with the ratio of 1:2
Answer: x = 2.8283
Step-by-step explanation:
pythagorean theory or sohcahtoa or sin law
T = 60' and T = 45': S = 90' : T = 45' : R = 90'
t = 3.464
sin law (i can't rlly show u)
q = 3.99
if u don't know what q is, it is the length of the middle line also known as RT
then u do
180 - 45 - 90 = Q
45 = Q
with 45 we can do sin law again
x = 2.8283 is the length of x
Answer: 9
Step-by-step explanation: To get the area of a square you do length times width. It has to be the same number so the square root of 81 is 9. Therefore your answer is 9.
Answer:
<h3> 63.25m</h3>
Step-by-step explanation:
The area of the square wall = L² where;
L is the length of the wall.
Given
Area of the mosaic = 4000m²
Substitute into the formula and get L
4000 = L²
Square root both sides
√4000 = √L²
√4000 = L
Rearrange
L = √4000
L = 63.25m (to the nearest hundredth)
<h3>Hence the length to the nearest hundredth is 63.25m</h3>
Answer:
Resulting plot in the image attached
Step-by-step explanation:
Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".
We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:
When x = 0 then: 
So we plot the value (0,-3) on the x-y plane.
When x = 2 then: 
So we plot the value (2,-2) on the x-y plane.
When x = 0 then: 
So we plot the value (4,-1) on the x-y plane.
Please see the points and the resulting line in the image attached
