Answer:
x = √21.
Step-by-step explanation:
Triangles ADB and BCD are similar.
So their corresponding sides are in the same ratio:
x / 7 = 3 / x
x^2 = 21
x = √21.
13. five plus <em>y</em> equal to negative two. y = -7
14. eight plus <em>h</em> equal to twelve. h = 4
15. negative thirteen plus four equal <em>n</em>. n = -9
First, we arrange the data from least to greatest:
90, 100, 100, 200, 203, 224, 233, 237, 245, 257, 264, 265, 265, 266, 277, 279, 285, 288, 288, 290, 290, 291, 291, 300
There are 24 data all in all. The mean is calculated by dividing by 24 the sum of all the data.
mean = (5828)/24242.83
The median of the number of jumps is the mean of the 12th and 13th term.

Answer:
a) 11.75 * 10^6
b) 1.35 * 10^-7
Step-by-step explanation:
Here, we want to find the sum and the difference
a) That would be;
(3.48 + 8.27) * 10^6
= 11.75 * 10^6
b) That would be;
(9.58-8.23) * 10^-7 = 1.35 * 10^-7
Answer:
Perimeter = 10 cm
Area = 6.25 cm²
Step-by-step explanation:
So to find the Perimeter of the square, we'll use this formula :
Hence, the perimeter would be 10 cm .
We know that the formula of Area to find the square is,
Note : The answer would always be in cm².
Hence, the area of the square would be 6.25 cm².
<em>We are done !</em>
