Answer:

d) 20

Step-by-step explanation:

To find possible side lengths use the triangle inequality theorem. The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. So for the measurements 6, 11, 20 to make a triangle 6+11 must equal at least 20, which isn't true. Therefore, 20 cannot be a measurement for this triangle.

the distance on the x values is 6 and the distance on the y values is 4

1/6 of 6 is 1 and 1/6 of 4 is .66

We subtract the coordinates from R

4-1 is 3

Answer:

1. y = 1/3x - 1

2. y = 2/5x

3. y = x + 8

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + c

where m is the slope and c is the y-intercept

So, we have the following based on the supplied values;

1. y = 1/3x - 1

2. y = 2/5x

3. y = x + 8

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

-98 = 7t

Step 2: Solve for t

Divide 7 on both sides:                    -14 = tRewrite:                                             t = -14

Step 3: Check

Plug in t into the original equation to verify it's a solution.

Substitute in t:                     -98 = 7(-14)Multiply:                               -98 = -98

Here we see that -98 is equal to -98.

∴ t = -14 is the solution to the equation.

What is the difference x/x^2+3+2 - 1/(x+2)(x+1)

Answers

Answer:

#4,   x-1/(x^2+3x+2)

Step-by-step explanation:

x/(x^2+3x+2) - 1/((x+2)(x+1))

Convert the 1/((x+2)(x+1)) to 1/(x^2+3x+2)

now you have a common denominator to subtract

x/(x^2+3x+2) - 1/(x^2+3x+2)

results x-1/(x^2+3x+2)

Answer: Choice B)  y = (-2/3)x + 6

===================================================

Work Shown:

2x+3y = 18

3y = 18-2x ..... subtract 2x from both sides

3y = -2x+18

y = (-2x+18)/3 .... divide both sides by 3

y = (-2x)/3 + 18/3

y = (-2/3)x + 6

-----------

As a quick shortcut, anything in the form Ax+By = C will convert to y = (-A/B)x+(C/B) when you solve for y.

The slope is -A/B and the y intercept is C/B

If the surface area of a sphere is 144pi square centimeters, what is the length of the radius of the sphere, in centimeters

Answers

Answer:

6cm

Step-by-step explanation:

The formula for the surface area of a sphere = 4πr²

From the Question, we are given:

The surface area of a sphere = 144pi square centimeters = 144π cm²

The length of the radius of the sphere, in centimeters is calculated by:

4πr² = 144π

Divide both sides by 4π

4πr²/4π = 144π/4π

r² = 36

Square root both sides

√r² = √36

r = 6cm

Therefore, the length of the radius of the sphere, in centimeters is 6 centimeters.

how far can you run in 5/7 of a hour if you run at a speed of 8 2/5 miles per hour

Answers

Answer:

6 miles

Step-by-step explanation:

At a speed of 8 2/5 miles per hour, you can run a distance of 6 miles

How to find distanceSpeed = 8 2/5 miles per hour

Time taken = 5/7 of a hour

Distance = x

Speed = distance / time taken

8 2/5 = x ÷ 5/7

42/5 = x ÷ 5/7

cross product

42/5 × 5/7 = x

x = (42×5) / (5×7)

= 210/35

= 6 miles

Therefore, you can run a distance of 6 miles at a speed of 8 2/5 miles per hour
