Answer:
12 square feet
Step-by-step explanation:
Just multiply the surface area of the original prism by 1/2 to get your answer (divide by two).
Answer:
Y=5/2x-3
Step-by-step explanation:
The equation's slope is -4/10, which simplifies to -2/5. The reciprical of this, 5/2, is the slope of a perpendicular line. The first possibility you commented is the only one to have this slope.
Answer:
<h2>x = 35</h2>
Step-by-step explanation:
Because the angles are vertical angles, they must be equal.
3x + 7 = 112
3x = 105
x = 35
Check
3(35) + 7 = 112
112 = 112 Correct
Answer:
c = 3.24
(x+1.8)²
Step-by-step explanation:
The question wants you to fill in the last term.
To find the last term, you must use the formula (b/2)^2.
Let's use this formula for the equation you gave: x²+3.6x+c
c = (b/2)²
c = (3.6/2)²
c = 3.24
That is the value of c.
Let's plug in c in the last term for better understanding.
x²+3.6x+3.24 is now factorable.
- You can complete the square or use the quadratic formula to factor.
The factored form will turn out to be : (x+1.8)²
Answer:
Area = 8.1902ft² (Rounded up to 4 decimal places)
Step-by-step explanation:
Let side a = 7.2ft, side b = 3.4ft and angle β = 42°
Area of the triangle will be given by:
1/2 × a × b × sinβ
Area = 1/2 × 7.2 × 3.4 × sin 42°
Area = 8.1902 ft² (Rounded up to 4 decimal places)
