What multiplies to 378 and adds to -51

Answers

Your answer would be -9 & -42.

Here's why ...
(-9)*(-42) A negative times a negative equals a positive (378).
Now, -9-42=-51 & you add these because you have two negatives.

Hope this makes sense & helps you ! (:

Which of the following best describes the base of a pyramid?A. It can be any polygon.
B. It is a circle.
C. It must be a square.
D. It is a triangle.

Answers

Answer:

A. It can be any polygon.

Step-by-step explanation:

A pyramid is a polyhedron with a base, which can be any polygon, but is most often a square.

When the base is a triangle, the pyramid has a total of four faces.

The famous Egyptian pyramids have square bases and four triangular faces. As the number of sides increases in a pyramid, it begins to look like a cone.

So, we can say A and C are both correct. But we will go with A as a square will also be considered in it.

What is a situation in which you might locate points on a coordinate grid?

Answers

A situation could be when you have a y=axsquared+bx+c equation. You'd find the X, or vertex, by doing x=-b divided by 2•a. Then you'd plug in x and find y. Now you have a point you can plot. To find another, you can find the y-intercept by plughing in 0 for x and finding another y.

Express the ratio 45 seconds to 30 minutes as a fraction in simplest form.

Answers

Answer: The required ratio in simplest form is 1 : 40.

Step-by-step explanation: We are given to express the ratio 45 seconds to 30 minutes as a fraction in simplest form.

We know that

1 minute = 60 seconds.

So, 30 minutes = (30 × 60) = 1800 seconds.

Therefore, the ratio is given by

$45~\textup{seconds}:30~\textup{minutes}\n\n=\frac{45~\textup{seconds}}{30~\textup{minutes}}\n\n\n=\frac{45~\textup{seconds}}{1800~\textup{seconds}}\n\n\n=(1)/(40)\n\n=1:40.$

Thus, the required ratio in simplest form is 1 : 40.

$1min=60s\to30min=30\cdot60s=1800s\n\n45s:30min=45s:1800s=45:1800=(45)/(1800)=(45:45)/(1800:45)=(1)/(40)$
