Answer:
62 degrees
Step-by-step explanation:
Cos ? = 25 / 54
25 / 54 = 0.4629
Cos-1 of 0.4629 is 62.4215
Round to the nearest degree
62.4215 = 62
2x + 5 ≤ x - 3
We can treat this like a usual algebraic equation.
<em><u>Subtract x from both sides.</u></em>
x + 5 ≤ -3
<em><u>Subtract 5 from both sides.</u></em>
x ≤ -8
Thus, x is less than or equal to the quantity -8.
We can test this by plugging in two values into the original inequality: a number greater than -8, and a number less than -8.
2x + 5 ≤ x - 3
We'll use 2 first.
2 * 2 + 5 ≤ 2 - 3
9 ≤ -1 × this is incorrect
Now we'll use -10
2x + 5 ≤ x - 3
2 * -10 + 5 ≤ -10 - 3
-15 ≤ -13 √ this is correct
Answer:
108 cubic units
Step-by-step explanation:
If X = 2 units, Y = 9 units, and Z = 6 units, then what is the volume of the rectangular prism shown above?
Volume of a rectangular prism XYZ = Length × Width × Height
= 2 unit × 9 unit × 6 unit
= 108 cubic units
A) 40
becuase you know one angle 50 and the intersection means 90. A triangle is 180, and 50+90=140. To get 180 the last angke would have to be 40.
P(brown hair) + P(blue eyes) - P(brown hair and blue eyes) + P(neither brown hair nor blue eyes) = 30
15 + 17 + 6 - P(brown hair and blue eyes) = 30
P(brown hair and blue eyes) = 38 - 30 = 8
Therefore, there are 8 students that have brown hair and blue eyes.
