Answer:

2.5

Step-by-step explanation:

equation the two areas in an equation and they are equal

\frac{1}{2} base \times height = length \times  \: width

but the width is w

substituting the values,

\frac{1}{2} (6)(5) = 6 \times w \\ 15 = 6w \\ w =  \frac{15}{6 =}  =  \frac{5}{2 }  = 2.5

Answer:

w = 3 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the height )

Here b = 5 and h = 6 , then

A = \frac{1}{2} × 5 × 6 = \frac{1}{2} × 30 = 15 cm²

Now the area of the rectangle is 15 cm²

area = length × width , that is

5w = 15 ( divide both sides by 5 )

w = 3 cm

(N^3 - N^4) - (3n^3- 7n^4)
Free_Kalibri [48]
If you would like to solve (n^3 - n^4) - (3n^3 - 7n^4), you can do this using the following steps:

(n^3 - n^4) - (3n^3 - 7n^4) = <span>n^3 - n^4 - 3n^3 + 7n^4 = n^3 - 3n^3 - n^4 + 7n^4 = -2n^3 + 6n^4
</span>
The correct result would be <span>-2n^3 + 6n^4.</span>

Suppose cos(O) = 12/13, Quadrant I. Find sin(O).<br> A:13/12<br> B:5/13<br> C:13/5<br> D:5/12
noname [10]

Answer:

B: 5/13

Step-by-step explanation:

pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 5

sin = opp/hyp

sin 5/13

Hope this helps
