Answer: True
Think of a 3D box. It has 6 faces and the surface area is the total of all six individual rectangular faces. This idea applies to any polyhedron.
Answer:
4 star fruit.
Step-by-step explanation:
16/8 = 2
each star fruit is 2 dollars
so 8/2 = 4
you can buy 4 star fruit for 8 dollars.
Answer:
1 / 8
Step-by-step explanation:
I'm assuming that is meant to be 3/4 and 1/6...
Area = Length * Width
A = 3/4 * 1/6
A = 3 / 24
simplify the fraction to get your answer
Answer:
x = 6.39, y = 1.69 is the solution of the given equation system.
Step-by-step explanation:
Here, the given set of equation is:
5 x = 15 + 10 y ⇒ 5 x - 10 y = 15 ...... (1)
3 x +7 y = 31 ............. (2)
Now, the coefficient of x in first equation id 5 and in second is 3.
So, MULTIPLY (1) with 3 and (2) with -5 , we get:
15 x - 30 y = 45
-15 x- 35 y = -155
<u>ADD BOTH EQUATIONS ,</u> we get:
15 x - 30 y -15 x- 35 y = 45 - 155
or, -65 y = -110
or, y = 110/65 = 1.69
Put y = 1.69 in 3 x +7 y = 31 , we get:
3(x) + 7 (1.69) =31
⇒ 3 x = 19.17 or x = 6.39
Hence, x = 6.39, y = 1.69 is the solution of the given equation system
Answer:
Step-by-step explanation:
Well, there is no given equation, but I can tell you that perpendicular lines have OPPOSITE <em>MULTIPLICATIVE INVERSE </em><em>[</em><em>RECIPROCAL</em><em>]</em><em> </em><em>rate of changes</em> [<em>slopes</em>].
Ex: 2 --> -½; -2 --> ½
