Answer:
42 because 3 tens is 30 and 12 ones is 12. so you do 30 + 12 = 42
Solve for x: x^2+4x-5=16x
first take 16x from both sides of the equation
x²-12x-5=0
now we have a quadratic. we can solve it by using the quadratic formula
x=-b plus or minus the square root of b²-4ac all divided by 2a
where a=1, b=-12 and c=-5
plug these numbers into the formula
x=12 plus or minus the square root of 144-4x1x-5 all divided by 2
<span>x=12 plus or minus the square root of 164 all divided by 2
or in decimal form </span>x = {12.403124237, -0.403124237}
50 x 3.14 = 157 i think this is the answer
Answer:
37
Step-by-step explanation:
Right Scalene Triangle
Side a = 37
Side b = 12
Side c = 35
Angle ∠A = 90° = 1.5708 rad = π/2
Angle ∠B = 18.925° = 18°55'29" = 0.3303 rad
Angle ∠C = 71.075° = 71°4'31" = 1.2405 rad
C=71.075°B=18.925°A=90°b=12a=37c=35
Area = 210
Perimeter p = 84
Semiperimeter s = 42
Height ha = 11.35135
Height hb = 35
Height hc = 12
Median ma = 18.5
Median mb = 35.51056
Median mc = 21.2191
Inradius r = 5
Circumradius R = 18.5
Vertex coordinates: A[0, 0] B[35, 0] C[0, 12]
Centroid: [11.66667, 4]
Inscribed Circle Center: [5, 5]
Circumscribed Circle Center: [17.5, 6]
Answer:
8x; x ≤ $23.75
Step-by-step explanation:
You have to buy 8 trains with 190 dollars. You can't use more money or have more trains.
8x ≤ 190
Divide by 8 on both sides.
x ≤ $23.75 per train
