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.

HELP
Is this right or no caused I just wanna make sure
===================================================
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
Helpppppp
Show workings
Answer:
C
Step-by-step explanation:
So this one is pretty much like the last one
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
2 -.66 =1.33
The 1/6 point is at (-3,1.33)

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

Work out the volume of this sphere.
Give your answer to 1 decimal place.
Spheres
Vol = ar
19 cm
Answer:
The volume is;
3951.8 cm^3
Step-by-step explanation:
As we can see, the sphere diameter is 19 cm
Radius is half of this which is 19/2 = 9.5 cm
Putting this in the area , we have
4/3 * 3.142 * 9.5^3 = 3951.8

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

From the equation y−3=−2(x+1), identify the slope and a point on the line.
Answer:
slope = - 2, point on line = (- 1, 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 2(x + 1) ← is in point- slope form
with slope m = - 2 and (a, b ) = (- 1, 3 )
The slope of equation y−3=−2(x+1) is -2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y−3=−2(x+1)
Using Slope- Intercept form
y= mx + b
So, the slope for the equation is -2.
Hence, the slope is -2.

how far can you run in 5/7 of a hour if you run at a speed of 8 2/5 miles per hour
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 hourTime taken = 5/7 of a hourDistance = xSpeed = 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
