Answer:
(1.2×3)500
Step-by-step explanation:
the 1.2 factor will be multiplied by the hours given then times that by the starting amount of bacteria.
Answer:
The surface area of a sphere is calculated by formula:
A = 4 x pi x radius^2
=> radius = sqrt(A/(4 x pi) = sqrt(4534.16/(4 x pi)) = 19 (cm)
Hope this helps!

Answer:
Hence after solving the given equation we get <em>x = 13/20.</em>
Step-by-step explanation:
<em>Given:</em>
<em>-3 x + 0.1 + 10 x = x + 4</em>
<em>-3 x + 10 x - x = 4 - 0.1</em>
<em>6 x = 3.9</em>
<em> x = 
</em>
<em>x = 
</em>
<em>x = 
</em>
What we know:
Area=l x w
vertices at (-4,0),(-3,1), (0,-2),(-1,-3)
pythagorean formula=a²+b²=h²
What we need to find:
Area
Finding length:
Length of rectangle is from point (-4,0) to (-1,-3), found it by plotting the points on graph paper. Went down 3 units and right 3 units to go from one point to the other, these are the a and b in the pythagorean formula.
a²+b²=h²
(3)²=(3)²=h²
9+9=h²
18=h²
√18=√h²
√18=h
Finding width:
Width of rectangle is from point (-4,0) to (-3,1), found it by plotting the points on graph paper. Went up 1 unit and right 1 unit to go from one point to the other, these are the a and b in the pythagorean formula.
a²+b²=h²
(1)²+(1)²=h²
1+1=h²
2=h²
√2=√h²
√2=h
Now we can find area,
Area= l x w
= √18 x√2
=√36=6
Area=6
Remember that when we square root a number we get two solutions, one negative and one positive but since length, width and area are positive we only use positive solutions.
