Answer: last option. 9.2
Step-by-step explanation:
The pythagoreon theorm tells us, a^2+b^2 = c^2. We can substitute these values, so 7^2 + 6^2 = x^2 => 49+36 = x^2 => root of 85. The root of 85 is 9.219 something so you can round 9.219 to 9.2.
Step-by-step explanation:
4.00x + 5.75y = 4.70
x + y = 58.75
I dont know the answer but I believe that is the formula
(<span>4/9)/x = 12 </span>
<span>12x = 4/9 </span>
<span>x = 4 / (9•12) = 1 / (9*3) = 1/27</span>
Answer:
original height = .2(8) + 13.4 = 15 inches
Step-by-step explanation:
To find the original height you multiply .2 by 8 to see how much was burned and then you add that to whats left (13.4) to give you the original height.
You find the slope by using the slope intercept form. y=mx+b and m is the slope. so we simplify it to y-7=8x-112. and y=8x-105. and 8/1 is the slope. which is a.
