Answer:
<em>1,172.5cm²</em>
Step-by-step explanation:
Total surface area of a box = 2(LW + WH + LH)
L is the length = 11.5cm
W is the width = 7cm
H is the height = 1.5cm
Substitute
TSA = 2(11.5(7) + 7(1.5) + (11.5)(1.5))
TSA = 2(80.5+10.5+17.25)
TSA = 2(117.25)
TSA = 234.5cm²
<em>Hence the total surface area of a stack of five such compact disc boxes will be 5(234.5) = 1,172.5cm²</em>
Answer: 4.83
Step-by-step explanation:
2.3*2.1= 4.83
Answer:
P'(-6, -4)
Step-by-step explanation:
The (x, y) coordinates of the plotted point P are (-2, 2).
Putting those values into the translation formula, you get ...
(x, y) ⇒ (x -4, y -6)
(-2, 2) ⇒ (-2 -4, 2 -6) = (-6, -4)
The coordinates of the translated point P' are ...
P'(-6, -4)
Answer:
The distance of the last ramp is <u>10</u> feet.
Step-by-step explanation:
From the options and the question, I assume that the height of the ramp is 6 feet. Pythagorean theorem states:
a² + b² = c²
where <em>c </em>is the hypotenuse, and <em>a</em> and <em>b</em> are the legs of the triangle. In this case:
6² + 8² = x²
√100 = x
10 ft = x
