Our triangle is ABC with ∠C = 90°
1) AB² = BC² + AC² (Pythagorean theorem)
25² = 20² + AC²
AC² = 625 - 400
AC² = 225
AC = 15
2) PΔABC = AB + BC + AC = 25 + 15 + 20 = 60
3) SΔABC = AC * BC * 1/2 = 15 * 20 * 1/2 = 150
Answer: the perimeter is 60 cm and the area is 150 cm² .
Answer:
Yes!
Step-by-step explanation:
Because, x-intercepts are not being repeated and pass the vertical line test.
Hello!
The Correct Answer are:
1. <span>C. 31,536,000 seconds
2. </span><span>C. 7,700,000
3. </span><span>90,000 meters
4. </span><span>A. 1,260 and 151,200
5. </span>67 feet
6. B and D
7. 15 x 24 = 360 rings and in another case we have 12 rows and each has 18 rings so in total we have : 12 * 18 = 216 so jewelry store has (360 - 216) rings more than other case so jewelry store has 144 rings more than other case.
8. 23 because 195 + 127 = 322 322/14 = 23
9. B and C
10. We know that 1 hundred= 100= 1*10^2. Therefore, 6,000 hundreds is equal to:
6,000*(1*10^2)= 600,000
Because 600,000 ≠ 6,000,000, Carlos is wrong.
Hope this All Helps! Took me Time!
Have A Wonderful Day! :)
