Answer:
144 cm
Step-by-step explanation:
Bottom: 4x11 = 44
Side 3x4x1/2 = 6
Other side = 6 (same)
Slant = 3, 4 and the hypotenuse is 5 (pythagroem triple )
5x11 = 55
Back: 3x11= 33
44+6+6+55+33= 144
The surface area of the prism will be given by:
SA=(surface area of triangles)+(surface area of rectangles)
surface area of triangles=2(1/2*3*4)=12 sq. units
area rectangles
the length of the hypotenuse will be:
c²=a²+b²
c=√(3²+4²)
c=√25
c=5
area=(3*5)+(4*5)+(5*5)=60
Total area=60+12=72 sq. units
Answer: 72 sq. units
Answer:
Step-by-step explanation:
To solve the quadratic equation, rearrange it into .
This quadratic is not factorable and to solve needs the quadratic formula.
The quadratic formula is . Here a=1, b=5, and c=-8.
Substitute and you'll have:
Answer:1/21
Step-by-step explanation:
Find the common denominator, 21
5/7 becomes 15/21 and 2/3 becomes 14/21
Then subtract 15/21 - 14/21 = 1/21
