Answer:

Option 4.

Step-by-step explanation:

When two adjacent angles are formed at a point on a line so that sum of their measures is 180°, angles are called as supplementary to each other.

In the figure attached, ∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

Option 4. is the right answer.

What is the value of x in the equation 2x+3y=36y when y=6?

jonny [76]

Answer:

y = 6 so

2x + 3y = 36y is equal to:

2x + 3*6 = 36*6

-> 2x + 18 = 216

We must now move 18 to the other side of the equation. As we do that, we also change it's sign to negative 18:

2x = 216 - 18

We simplify this

2x = 198

Now, that we got to this point, we know that 2x is equal to 198. To find x we must divide the both sides of the equation by two:

2x/2 = 198/2

And we get that

x = 99

A box has a volume of 546cm3 and a surface area of 422cm2. What are the Length, Width and Height?

Klio2033 [76]

We know that the formula for the volume of a box is:

$V =lwh$

Where:
l = length
w = width
h = height

The formula of the surface area of a box is:
$SA=2(lw+lh+wh)$

Based on the given we know the following:
$546cm^{3} =lwh$

and

$422cm^{2}=2(lw+lh+wh)$

If we factor out the given volume, you can come up with 3 numbers that will satisfy the surface area formula:

$546=6*7*13$

Let:
l = 6cm
w = 7cm
h = 13cm

Now let's try this on the surface area formula:
$422cm^{2}=2(lw+lh+wh)$
$422cm^{2}=2((6cm*7cm)+(6cm*13cm)+(7cm*13cm))$
$422cm^{2}=2(42cm^{2}+79cm^{2}+91cm^{2})$
$422cm^{2}=2(211cm^{2})$
$422cm^{2}=422cm^{2}$

The answer is then:
l = 6cm
w = 7cm
h = 13cm

Any order would be fine.
