Answer:
7/3 in decimal form it's 2.3 repeated
Step-by-step explanation:
The height is 4 feet. You calculate the area by length times height. So what multiplied by 15 is 60? Well, 15ft x 4ft = 60ft^2
Answer:
D. 1662 cm
Step-by-step explanation:
A=πr2=π•23≈1661.90251cm²
which is 1661.9
but of course you have to round up for 1662 cm :)
angle 1+ angle 2=180 supplementary angles add up to 180
angle 2=x assign angle a variable
angle 1= 3x-38 find equation for first angle
3x+x-38=180 set both angles added together equal to 180
4x-38=180 combine like terms
4x=218 add 38 to both sides
x=54.5 divide by 4
angle 2= 54.5
angle 2= (3x54.5)-38 plug back in and solve
angle 1= 125.5
Answer:
Step-by-step explanation:
We know that for two similar matrices 
and 
exists an invertible matrix 
for which
![[tex]B = P^{-1} AP](https://tex.z-dn.net/?f=%5Btex%5DB%20%3D%20P%5E%7B-1%7D%20AP)
