Answer:
She must score an 81
Step-by-step explanation:
(74 + 92 + 83 + 98 + 100 + x) / 6 = 88
(x+447)/6 = 88
x+447 = 528
x = 81
Answer:
The answer would be 16
Step-by-step explanation:
subtract the top numbers, so 4-2 which would be 2. then simplify the expression which gives you 2^4. and 2 to the 4th power is 16
Answer:
60.2 m
Step-by-step explanation:
Let x represent the width of the river. The distance from the point across from the tree to the second point is 15 m. The angle from this point to the tree across the river is 76°.
This makes the side opposite the angle x, the width of the river. It also means the 15 m side is adjacent to this angle.
The ratio opposite/adjacent is the ratio for tangent; this gives us the equation
x/15 = tan(76)
Multiply both sides by 15:
15(x/15) = 15(tan(76))
x = 15(tan(76)) ≈ 60.2
To factor (x² +10x+24); you first have to ask yourself, what 2 numbers will multiply and give me positive 24, but add and give me positive 10? After listing your factors, (1,24)(2,12)(3,8)and (4,6); you decide that (4*6)=24 & adds to get you 10. Meaning that (x²+10x+24) factors are (x+4)(x+6).
Now algebraically, there wouldn't be any other possible value of b, 6, because if you put (-6) & (4), those numbers will multiply and give you (-24) and add & give you (-2); & that is not what you're looking for.
I hope I explained this enough for you to understand. (:
$339.94 you're just adding everything together by the seems of it lol.
