1) calculate the volume of the tri prism 2) find area of the base face 3) find the height 4) multiply area of the triangle base time height 5) answer will be in cubic units
y = -1/2x + 5 should be your equation because it is 5 ft above sea level and its eroding, or going down, 1 ft per 20 years. So every year, the sand dune erodes 1/20 ft more.
Hope this helps!
It took 9 hours of labor. 500 - 140 = 360...... 360 / 40 = 9.
Answer: 9.
Answer:
9x2 +42x + 24 <u>is</u> (x + 4) (9x + 6)
9x2 + 30x + 24 <u>is</u> (3x + 6) (3x + 4)
9x2 + 58x + 24 <u>is</u> (9x + 4) (3x + 4)
I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)
Equation: 120 ≥ 10n + 20
Subtract 20 from both sides,
100 ≥ 10n
Divide both sides by 10,
10 ≥ n
It means, it is equal or Smaller than 10.
So, the answers would be: 7, 8, 9, 10
Hope this helps!
