This is a linear equation however.

A customer orders 8 bags of rice that each weigh 1/2 kg, and 12 packets of popcorn that each weigh 150 g. What is the total mass
Nonamiya [84]
Rice: .5(8) = 4kg (4000 g)
Popcorn: 150(12) = 1800 g

Total mass = mass of rice (4000 g) + mass of popcorn (1800g)

So...

Total mass = 5,800 g (or 5.8 kg)

C. 25 D. 6<br> Geometry math question please help me
Sophie [7]

Hello!

According to the dashes, you can see that the two separate triangles are congruent. Therefore, these two angles are congruent. We will solve below.

6n-10=50

We add 10 to both sides.

6n=60

Divide both sides by 6.

n=10

Therefore, our answer is A) 10.

I hope this helps!

Which is the focus of a parabola with equation y2 = 4x?
statuscvo [17]

Answer:

(1, 0)

Step-by-step explanation:

Please write this as y^2 = 4x; the " ^ " indicates exponentiation.

The appropriate equation for a horizontal parabola that opens to the right is

y^2 = 4px

Here, we are told that  y^2 = 4x; this tells us that 4p = 4, and so p = 1.  

Again, this parabola is a horizontal one and it opens to the right.  p = 1 is the distance of the focus from the vertex, and in this case p = 1.  Thus, the focus is at (1, 0) (situated on the x-axis).
