To determine the extent of how many times greater is the number of bacteria in petri dish A than petri dish B, we simply have to take the ratio of the two.
1.75 x 10^18 / 6.25 x 10^15 = 280
So the bacteria in petri dish A is 280 times larger.
In scientific notation:
2.8 x 10^2
Hope this helps :)
Answer:
Triangle UVT and TSR are isosceles triangles (two equal sides).
Angle WUV = Angle WTV (base angles of isosceles triangle)
Angle RTS = Angle TRS (base angles of isosceles triangle)
Line VW is perpendicular to line UT.
Angle WTV = Angle RTS (vertically opposite angles)
Angle WTR = Angle VTS (vertically opposite angles)
Answer:
y=-1/2x+8
Step-by-step explanation:
Perpendicular lines have opposite reciprocals:
So the slope -2 becomes 1/2 because the reciprocal of -2 is -1/2, which its opposite is 1/2
So your answer should be something similar to y=-1/2x+8
Answer:x=2 and y=3
Step-by-step explanation:
Given that y=2x-1
Then, 3x+2y=12
3x+2(2x-1)=12
3x+4x-2=12
7x=14
x=2
y=2(2)-1
y=3
Answer: Well, once you add all of the prices together to see how much she spent after buying these items you'll see it totals up to $7.02. Veronica is correct in believing she should've received more change as she was only given 3 quarters which is 75 cents and 4 pennies which adds up to 79 cents. She should've actually received $2.98.
