Answer:
b= (2a+11)/5
Step-by-step explanation:
5x + 2y = 9
2y=9-5x
y= 9/2 - 5x/2
slope, m1= -5/2
for perpendicularity, m1 × m2 = -1
slope for QR= m2=
m2 is 2/5
5(b-3)=2(a-2)
5b-15=2a-4
5b=2a-4+15
5b= 2a+11
Okay so instead of in place value going 1,10,100 in binary you go 1,2,4 so it would go 256:1,128:0,64:0,32:1,16:1,8:0,4:0,2:0,1:1=1+16+32+256=305. So 100110001=305 in binary. It is also would take 1+1/2 bytes or 9 bits to store the number. Hope this helps.
45 seconds the difference from 7 45 to 8 is 15 plus another 30 to get 8:30 which is a 45 second difference
3V = π r2 h is the volume for r .
What is volume ?
- Each thing in three dimensions takes up some space. The volume of this area is what is being measured. T
- he space occupied within an object's borders in three dimensions is referred to as its volume.
- It is sometimes referred to as the object's capacity.
You must alter the equation using algebraic operations such that it reads
V = 1/3 r2 h.
The second hint is to always operate on the side opposite the equal sign when performing an operation.
Start by multiplying both sides by 3.
3 • V = 3(1/3) π r2 h
We now have a brand-new equation:
Rewrite 3V = 3(1/3) r2 h.
3V = π r2 h
