Answer:
a= 11/30
Step-by-step explanation:
Divide the 5 1/2 miles by the 15 minutes
5.5/15= .36
.36 = 11/30
Answer:
x = 14
< A = 58 degrees
< B = 52 degrees
< C = 70 degrees
Step-by-step explanation:
Recall that the addition of the three internal angles of a triangle must render 180 degrees, then we can write:
<A + <B + <C = 180
and now replace with the algebraic expressions given for each angle:
2(x + 15) + 3 x + 10 + 5 x = 180
eliminate parenthesis
2 x + 30 + 3 x + 10 + 5 x = 180
combine like terms
10 x + 40 = 180
subtract 40 from both sides
10 x = 140
divide both sides y 10 to isolate x
x = 14
Now that we know x, we can calculate each of the angles using the fiven expressions:
< A = 2 (x + 15) = 2 (14 + 15) = 2 * 29 = 58 degrees
< B = 3 x + 10 = 3 * 14 + 10 = 52 degrees
< C = 5 x = 5 * 14 = 70 degrees
3.05 - take the 7 highest & lowest #s then take the average of the final two numbers (3.0 & 3.1)
Answer:
cone height formulas are, h = 3V/πr 2 and h = √l2 - r2, where V = Volume of the cone, r = Radius of the cone, and l = Slant height of the cone.
Answer:
![x = - 0.461](https://tex.z-dn.net/?f=x%20%3D%20%20-%200.461)
Step-by-step explanation:
![x - \sqrt{2 } + \sqrt{2} = 3 \sqrt{3} - 4 \sqrt{2} \\ x = 3 \sqrt{3} - 4 \sqrt{2} \\ x = - 0.461](https://tex.z-dn.net/?f=x%20-%20%20%5Csqrt%7B2%20%7D%20%20%2B%20%20%5Csqrt%7B2%7D%20%20%3D%203%20%5Csqrt%7B3%7D%20%20-%204%20%5Csqrt%7B2%7D%20%20%5C%5C%20x%20%3D%203%20%5Csqrt%7B3%7D%20%20-%204%20%5Csqrt%7B2%7D%20%20%5C%5C%20x%20%3D%20%20-%200.461)
