Answer:
9 units.
Step-by-step explanation:
Let us assume that length of smaller side is x.
We have been given that the sides of a quadrilateral are 3, 4, 5, and 6. We are asked to find the length of the shortest side of a similar quadrilateral whose area is 9 times as great.
We know that sides of similar figures are proportional. When the proportion of similar sides of two similar figures is , then the proportion of their area is .
We can see that length of smaller side of 1st quadrilateral is 3 units, so we can set a proportion as:
Take positive square root as length cannot be negative:
Therefore, the length of the shortest side of the similar quadrilateral would be 9 units.

−x3 + x2 − 25
5x3 + x2 + 13
5x3 + 5x2 − 19
Answer:
The answer is D
Step-by-step explanation:
Let's simplify step-by-step.
3x2−3+9x3−(4x3−2x2+16)
Distribute the Negative Sign:
=3x2−3+9x3+−1(4x3−2x2+16)
=3x2+−3+9x3+−1(4x3)+−1(−2x2)+(−1)(16)
=3x2+−3+9x3+−4x3+2x2+−16
Combine Like Terms:
=3x2+−3+9x3+−4x3+2x2+−16
=(9x3+−4x3)+(3x2+2x2)+(−3+−16)
=5x3+5x2+−19
Answer:
=5x3+5x2−19
Answer:
So minute hand will rotate in half an hour
Step-by-step explanation:
In one hour minute hand of clock rotate about 360°
So in half an hour minute hand clock rotate
We have to find how many minute hand rotate in radian
For conversion of degree to radian we have to multiply with
So
So minute hand will rotate in half an hour
To find the percentage of observations between two values in a normal distribution, we can convert the values to z-scores and use a z-table to find the corresponding areas. In this case, the percentage of observations between 0.372 and 0.428 is 68.26%.
To find the percentage of observations that will lie between 0.372 and 0.428 in a normal distribution with a mean of 0.40 and standard deviation of 0.028, we need to find the area under the curve between these two values.
Using a standard normal distribution table or z-table, we can convert the values to z-scores by subtracting the mean and dividing by the standard deviation. The z-score for 0.372 is (0.372 - 0.40) / 0.028 = -1, and the z-score for 0.428 is (0.428 - 0.40) / 0.028 = 1.
By looking up the corresponding area for these z-scores in the z-table, we find that the area to the left of -1 is 0.1587 and the area to the left of 1 is 0.8413. To find the percentage between -1 and 1, we subtract the smaller area from the larger area: 0.8413 - 0.1587 = 0.6826 or 68.26%.
