Step-by-step explanation:

Answer: 125 = 5³

625 = 5⁴

15625 = 5^6

Step-by-step explanation:

Tge question simply states that we should write the numbers given below in power of 5 and the number goes thus:

125 = 5 × 5 × 5 = 5³

625 = 5 × 5 × 5 × 5 = 5⁴

15625 = 5 × 5 × 5 × 5 × 5 × 5 = 5^6

Answer:

It is a proportional relationship. 1 step/2.5 Feet.

Step-by-step explanation:

First of all, you need to find out what a single step equals to feet.

If 6 steps is 15 feet, and 8 is 20, then 2.5 feet is the transition of proportional relationship. (15, 17.5, 20)

This means that the proportional relation ship is that every 1 step is equal to 2.5 feet.

Answer:

6+2(n+4) = (3-n)÷2

Step-by-step explanation:

6 + 2n + 8 = (3-n)/2

14 + 2n = (3-n)/2

multiply through by 2 to eliminate the denominator

28 + 4n = 3 - n

25 + 4n = -n

25 = -5n

n = -5

Answer:

slope is 8

Step-by-step explanation:

y=Mx+c

m is the slope therefore the slope is equal to 8

The slope of the line y = 8x - 10 is 8.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Given line is y = 8x - 10

Equation of a line in slope intercept form is given by,

y = mx + c

Here, m is the slope and c is the y intercept.

The given equation is in the slope intercept form.

y = 8x - 10

The coefficient of x is the slope.

So slope of the given line = 8

Hence the slope of the line y = 8x - 10 is 8..

Answer:

it is false as the sum of the degrees of the triangle should be 180 but here it is 188 so it is false

Answer:

Step-by-step explanation:

No relationship i belive

Answer: p(a given b) = p(a and b) / p(b)

a is the probability that they score.

b is the probability that they cross the blue line.

p(a and b) is given as .005

this is the probability that they cross the blue line and score.

p(b is given as .6

that's the probability that they cross the opposing blue line.

the formula becomes:

p(a given b) = .005 / .6 = .0083333333.....

that's what i get using the p(a given b) formula.

Answer:

y= 4 x=0 (0,4)

Step-by-step explanation:

5x+y=4

-5x +y=4

the 5x would cancel out because they equal zero

2y=4

divide both sides by 2

y=4

put the y into one of the equations

5x +4 =4

subtract 4 from both sides

5x=0

divide five from both sides

x=0/5

so x=0

Step-by-step explanation:

5x+y=4 --> y=-5x+4

Plug this into the other equation:

-5x+(-5x+5)=4

Simplify:

-10x=1

x=-.1 (save this answer)

Plug into first simplified equation:

y=-5(-.1)+4

[tex]h=6\\k=2.5\\n=3\sqrt{10}\\m=\sqrt{21}\\p=\sqrt{17}[/tex]

Step-by-step explanation:

All of the triangles in this problem are right triangles. This means that all of them contain a right angle, this is indicated by the box around one of the angles. The Pythagorean theorem is a property of the sides of a right triangle, this property, in the form of an equation, is as follows,

[tex]a^2+b^2=c^2[/tex]

Where (a) and (b) are the legs, that is, the sides that are adjacent to the right angle of a right triangle. The parameter (c) represents the hypotenuse, the side opposite the right angle of a right triangle. For each triangle, substitute the given side lengths, simplify, and solve for the unknown side.

[tex](h)^2+(8)^2=(10)^2\\h^2+64 = 100\\h^2=36\\h=6[/tex]

[tex](k)^2+(6)^2=(6.5)^2\\k^2+36=42.25\\k^2=6.25\\k=2.5[/tex]

[tex](n)^2+(\sqrt{10})^2=(10)^2\\n^2+10=100\\n^2=90\\n=\sqrt{90}\\n=3\sqrt{10}[/tex]

[tex](m)^2+(2)^2=(5)^2\\m^2+4=25\\m^2=21\\m=\sqrt{21}[/tex]
