Answer:

3 2/3

Step-by-step explanation:

The x value is the same for both points. So we're only trying to figure out the difference in the y values. One y value is three steps down from zero and one y value is 2/3 of a step up from zero. So the total vertical distance between the two points is 3 and 2/3.

a. For each of the Five Platonic Solids, count the number V of vertices, the number F of faces, and the number E of edges. Check

natita [175]

Answer:

1. The tetrahedron has 4 vertices, 6 edges and 4 faces. Then V-E+F=4-6+4=2

2. The cube has 8 vertices, 12 edges and 6 faces. Then V-E+F=8-12+6=2

3. The octahedron has 6 vertices, 12 edges and 8 faces. Then V-E+F=6-12+8=2

4. The icosahedron has 12 vertices, 30 edges and 20 faces. Then V-E+F=12-30+20=2

5. The dodecahedron has 20 vertices, 30 edges and 12 faces. Then V-E+F=20-30+12=2.

What is the slope of line<br> 4x+6y=24

Varvara68 [4.7K]

Y=mx+b
m is the slope
you need to get y on one side and all other numbers on the other
so here's the easiest way to do it:
just kinda take 4x (which is a positive number) and move it to the other side and change the sign. so then it turns into 6y=-4x+24 and then you divide both sides by 6 so then you get y=-4/6x+4 (4 over 6 like a fraction)
-4/6 is the slope

each hour, the number of bacteria in Dr. Nalls petri dish tripled. what percent is the population compared to the population the

Lelu [443]

Answer:

300%.

Step-by-step explanation:

Suppose the population is 100, then it rises to 300 after one hour.

So the requires percent is (300/100) * 100

= 300%.

In a lottery, a 4 digit number from 0000 to 9999 is randomly selected. Find the probability that the number selected begins with

Bingel [31]

Since the choices is from 0000 to 9999, therefore there are a total of 10,000 possibilities.

The possibilities that the number begins with a 3 and ends in a 2 or 0 is:

possibilities = 1 * 10 * 10 * 1 + 1 * 10 * 10 * 1 = 200

Therefore the probability is:

P = 200 / 10,000 = 0.02 = 2%

<span>So there is a 2% probability.</span>

What is the area of the composite figure? (6π 4) cm2 (6π 16) cm2 (12π 4) cm2 (12π 16) cm2

raketka [301]

The area of the considered composite figure is given by: Option: 6π + 16 cm²

<h3>How to calculate the surface area of a composite figure?</h3>

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

$\text{Area of composite figure} = \sum (\text{Area of composing figures})$

That ∑ sign shows "sum"

For this case, the missing image is attached below.

As visible, the area of the figure = Sum of area of those 3 semi circles + Area of that square(its square because it has 4 equal sides in which adjacent sides are perpendicular) in between.

The side of the square is of 2+2=4 cm( as half of its side is 2 cm), thus, Area of that square = 4² = 16 cm²

All those 3 semicircles has radius = 2 cm

Since radius is same, so area of those 3 semicircle is same = $\dfrac{\pi r^2}{2} = \dfrac{\pi (2)^2}{2} = 2 \pi\: \rm cm^2$

Thus, we get:

Area of the composite figure = $2 \pi +2 \pi +2 \pi + 16 \: \rm cm^2 = 6 \pi+ 16 \: \rm cm^2$
