Answer:
Your answer is 15.2
Step-by-step explanation:
use the formula a² + b² = c²
In this case, you know what a and c are.
a = 13
c = 20
Put those two into the formula.
13² + b² = 20²
13² = 169
20² = 400
169 + b² = 400
Bring 169 over to the other side to get b² by itself. do this by subtracting it from 400.
400 - 169 = 231
b² = 231
Now we need to get rid of the exponent. To do this, get the square root of both sides.
√b² = √231
b = 15.1986841536...
Finally, round your answer to the nearest tenth like the question tells you to.
15.2
Therefore:
b = 15.2
Answer:
Step-by-step Solution:
<u>Isolate the variable x to get the answer.</u>
- x − 2/5 = −1
- => x = -1 + 2/5
- => x = -1 + 0.4
- => x = -0.6
Hence, the value of x is -0.6.

Considering the area of a rectangle, it is found that the area of Bob's remaining plot of land is of 12.5 acres.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by the multiplication of these dimensions, that is:
A = lw.
In this problem, both the length and the width are divided in half, hence the proportion remaining is given by:
A = 0.5l x 0.5w = 0.25lw = 25% of the initial area.
Hence:
0.25 x 50 = 12.5.
The area of Bob's remaining plot of land is of 12.5 acres.
