Pythagorean theorem (picture provided)

Answer:

n= 6

Step-by-step explanation:

subtract 3 from both sides of the equation

it should wind up like this:

9-3=n+3-3

plus 3 and minus 3 cancel out, 9 minus 3 equals 6 so then the equation changes to this:

n= 6

Answer:

490

Step-by-step explanation:

Let us first count the handshakes between two gremlins. There are 20 gremlins, so there must be 20*19/2=190 handshakes between two gremlins, making sure to divide by two to avoid over-counting.

There are 15 imps that shake hands with each of the 20 gremlins, which makes 15* 20 = 300 handshakes between imps and gremlins.

Adding these up, you have $300 + 190 = 490 total handshakes.

Answer:

x=3 y=2

Step-by-step explanation:

y=2

2x+y=8

Substitute y=2 into the second equation

2x+2=8

Subtract 2 from each side

2x+2-2=8-2

2x=6

Divide each side by 2

2x/2 =6/2

Step-by-step explanation:

The apple, weighing 150g, contains 2.0% sugar by mass. Calculating this percentage, we find out that the apple contains 3.0g of sugar.

To find out how much sugar is contained in a 150g apple, where 2.0% of its mass is sugar, we use simple percentage calculations. We know that 1% of 150g is 1.5g (150/100), so 2.0% of 150g would be 2 times 1.5g, which comes to 3.0g. Thus, the apple contains 3.0g of sugar.

Answer:

28.27 and 12.60

Step-by-step explanation:

Answer:

First you find the slope:

(10-4)/2 = 6/2 = 3

Then you write a point-slope equation:

y-4=3x

in slope-intercept form:

y=3x+4

Answer:

The equation of the line is y = 3x + 4.

Step-by-step explanation:

First find the slope of the line:

Slope (m) = rise / run

= difference in y coordinates / difference in corresponding x coordinates

= (10-4) / (2 - 0)

= 6/2

= 3..

The line  is written as

y = m x + b

We have just found m (= 3). Now we find the value of b by substituting the point (0, 4) into this equation.

4 = 3(0) + b

b = 4.

So the required equation is y = 3x + 4.

Answer:

448

Step-by-step explanation:

aₙ = a₁ + (n-1)d

a₈ = a₁ + (8-1)d = a₁ + 7d

a₁₂ = a₁ + 11d

a₈ + a₁₂ = 246 = 2a₁ + 18d            a₁ + 9d = 123

a₁₀ + a₁₄ = a₁ + 9d + a₁ + 13d = 298     a₁ + 11d = 149

2d = 26

d = 13

a₁ = 6

a₃₅ = 6 + (35-1) x 13 = 448

Answer:

C

Step-by-step explanation:

Because it uses the Pythagorean Theorem. (a squared plus b squared equals c squared)

To find the slope (m), use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]        And plug in the two points

(-2, -1) = (x₁, y₁)

(4, -1) = (x₂, y₂)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{-1-(-1)}{4-(-2)}[/tex]  (two negative signs cancel each other out and become positive)

[tex]m=\frac{-1+1}{4+2}[/tex]

[tex]m=\frac{0}{2}[/tex]

m = 0            

Answer:

The slope is 0.

Answer:

a. Probability of landing on red = [tex]\frac{1}{5}[/tex]

b. See Explanation

Step-by-step explanation:

Given

A Spinner

Number of section = 10 (equal sized)

Number of red section = 2

Required

- Probability of landing on red

- Describe the probability in words

Calculating the probability of landing on red

The formula used in calculating probability is as follows

Probability = Number of required outcomes / Number of possible outcomes

In this case, the number of required outcomes is the number of red section.

Hence, number of required outcomes  = 2

And the number of possible outcomes is the total section of the spinner

Hence, Number of possible outcomes = 10

By Substitution

Probability of landing on red = [tex]\frac{2}{10}[/tex]

Probability of landing on red = [tex]\frac{1}{5}[/tex]

Describe the probability in words

From (a) above, we have that the probability of the spinner landing on color red is [tex]\frac{1}{5}[/tex]

This means that, for every five times, you spin the spinner, it's likely that one of the outcomes will be red.

The area that Harry will pace 105 ft.²

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).

If the area he paces divided by the area his apprentice paces equals three, then we can write it as;

J/a = 3

In ratio form,

J : a = 3 : 1

Where J. represent Harry and. a represent the apprentice. Hence,

Therefore, the area Harry will pace;

= ( 3/4) × 140 ft.²

= 105 ft.²
