Seth bought glow-in-the-dark stars to

Mathematics
1 answer:
kiruha [24]3 years ago
3 0

Answer:

Each constellation will have 5 little stars.

Step-by-step explanation:

First, let's organize the information we have:

  • 5 big stars
  • 25 little stars
  • Each constellation should have 1 big star
  • Each constellation should have the same amount of stars

Now, let's solve the problem:

  1. Each constellation should have 1 big star, and Seth has 5 big stars, so we can infer that there would<u> </u>be 5 constellations.
  2. Since each constellation have 1 big star, and the amount of stars in each constellation is the same, the amount of little stars in each constellation are the same.
  3. We have 25 little stars, and there are 5 constellations; 25 ÷ 5 = 5, so each constellation have 5 little stars.

What is the equation for this line?
zzz [600]

Answer:

The equation of the line is y = 2x - 3

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

  • m is the slope of the line,  m=\frac{y2-y1}{x2-x1}
  • b is the y-intercept (value y at x = 0)

Let us take two points on the line to find its equation

∵ Points (3, 3) and (0, -3) lie on the line

∴ x1 = 3 and y1 = 3

∴ x2 = 0 and y2 = -3

→ Use the rule of the slope above to find m

∵ m=\frac{-3-3}{0-3}=\frac{-6}{-3}=2

∴ m = 2

→ Substitute its value in the form of the equation above

∴ y = 2x + b

∵ b is the value of y at x = 0

∵ y = -3 at x = 0

∴ b = -3

→ Substitute it in the equation above

∴ y = 2x + -3

→ Remember (+)(-) = (-)

∴ y = 2x - 3

∴ The equation of the line is y = 2x - 3

6. Describe some things you could notice in two polygons that would help you decide
Goshia [24]

Answer:

Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase.

Step-by-step explanation:

In this question, we need to tell some things that could help to check if two polygons are scaled copy of each other or not.

Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase. For example, if a rectangle has a length of 10 and a height of 8, a scaled copy would be a length of 5 and a breadth of 4.

Another example is as follows:

If a rectangle has a length of 4 and a height of 3, a scaled copy would be a length of 8 and a breadth of 6.

Slope of (-2,-1) and (2,-3)
lina2011 [118]

SLOPE is the picture.

Point-Slope form is y+1=-1/2*(x+2)

The y=mx+b form is y=-1/2x-2

i hope its not confusing lol

I would say A. The volume of prism z is 4 times the prims y, and they are similar.

4 x6 is 24
They are similar
That’s really all you need to know.
Hope this helps!

1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded

2) c, e, and f
