Answer:
x=18
Step-by-step explanation:
Triangles add up to 180°, so 140+22+x=180 and then you simplify which is 162+x=180, then you subtract 162 on both side, getting x=18
Answer:
B
Step-by-step explanation:
To multiply scientific notation, multiply each part of the number.
(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12
Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.
The solution is B.
Answer:
The radius of the oil spill growing at 2 feet per minute
Step-by-step explanation:
Area of a circle is
Differentiating A with respect to r,
When 
,
The rate of growth of the spill is
This is equivalent to
Its the radius.
A is the point at the centre and B is a point on the circumference.
The distance between the centre and the circumference [ in this case - AB ] is the radius.
Hence, AB is the radius of the circle.
Answer:
50 softballs
Step-by-step explanation:
We will review case by case, to find out which one has less volume.
- One bowling ball, one ball, discarded.
- One basketball, one ball, discarded.
- Four dozen golf balls, a dozen are 12 and how are 4 dozen, would be 48 (12 * 4) there are two less than the balls than softballs, in addition to the fact that they give us the diameter in inches, the diameter always it is smaller than the circumference.
- 50 softballs, the largest number of balls, therefore the largest volume, in addition to the volume of each one is greater because they speak of circumference therefore it is greater than those that speak of diameter, that is, softball is more bigger than golf balls.
