Answer:
1.8 cm
6.3 cm²
Step-by-step explanation:
AC⊥BC
BD=BC=x
- (x+5)²+x²=7²
- x²+10x+25+x²=49
- 2x²+10x- 24=0
- x²+5x-12=0
- x=1.8
BC= 1.8 cm
Area of ABC= 1/2*1.8*7= 6.3 cm²
Answer:
<h2>B. 0.001</h2>
Step-by-step explanation:
<h3 /><h3>Your answer is B. 0.001.</h3>
Thank you ☺️☺️
No, u cant
a^2 + b^2 = c^2.....pythagorean theorem used on only right triangles...where a and b are the legs and c is the hypotenuse
a^2 + b^2 = 23^2
a^2 + b^2 = 529...so u would have to find 2 square numbers that add up to 529. There aren't any.

Step-by-step explanation:
The number of blue whales residing in a particular ocean is estimated to be four. Find the estimated amount of kills the blue whales would have consumed by the turn of the year.
Given that:
Amount of krills consumed per year = 1460000
Number of Blue whales = 4
Hence, the estimated consumption of the blue whales will be :
Number of Blue whales * estimated consumption per whale :
(4 * 1460000) = 5840000
Hence,
Estimated consumption of the Blue whales per year = 5.84 × 10^6
The perfect square are the squares of the whole number 1,4,9,16,25,36,49,64,81,100 here are the square roots of all the perfect from i to 100 1. estimate first get as close as you can by finding two perfect square roots your number is between
