A lime has a mass of 90 grams, and is in the shape of a sphere with radius 1 point
2.5 centimeters. What is the density of the lime?
The density of the lime is 1.38 g/cm^3.
What is the density of a lime?
Remember that the density is given by the quotient between mass and volume.
Here, the lime is a sphere with a radius of 2.5 cm, remember that the volume of a sphere of radius R is given by:
V = (4/3)*pi*R^3
So our lime has a volume:
V = (4/3)*3.14*(2.5 cm)^3 = 65.42 cm^3
And the mass is M = 90 grams, then the density is:
D = M/V = (90 g)/(65.42 cm^3) = 1.38 g/cm^3

A rectangle has a width of 6 units and a length of 2x+8 units. If the area is 108 units squared, what is the value of X?
Answer:
x = 5 units
Step-by-step explanation:
Hello!
We know that the area of a rectangle is the length multiplied by the width.
We can simply create an expression to solve for x.
Solve:
Area = length x width108 = 6(2x + 8)108 = 12x + 4860 = 12xx = 5The value of x is 5 units.

Answer:
v = [tex]\frac{7\sqrt{2} }{2}[/tex]
u = [tex]7[/tex]
Step-by-step explanation:
First, the angle on the far left is also 45 degrees.
So, v is equal to [tex]\frac{7\sqrt{2} }{2}[/tex] because this is a 45-45-90 triangle, so the sides opposite the 45-degree angles are congruent.
However, u is the side opposite the 90-degree angle, so it is equal to the other side value, multiplied by [tex]\sqrt{2}[/tex].
So, [tex]\frac{7\sqrt{2}}{2}*\sqrt{2}[/tex] is equal to:
[tex]7[/tex]

you are supposed to be able to do it your own, i think the maths teacher think in this way.
find the missing angle measures
Answer:
Step-by-step explanation:
180° ( n - 2 )
n = 6 sides
4( x )° + 2( x - 6 )° = 180° ( 6 - 2 )
4x + 2x - 12 = 720
6x = 732
x = 122
x° = 122 °
( x - 6 )° = 116 °
122° + 116° + 122° + 122° + 116° + 122° = 720°
How to understand the Triangle-sum Theorem?
Answer:
Its Simple All the angles in a triangle adds up to 180°
Step-by-step explanation:
∠A + ∠ B + ∠C = 180° NO matter what. You can also use this in inverse If you have two out of three angles then you can add the two angles you have and subtract the from 180 to get the measurement of the 3rd angle.

2. Now lets the change the base of both fractions into a common denominator and solve
⇒ [tex]\frac{5}{3}-\frac{1}{4} = \frac{5*4}{3*4} -\frac{1*3}{4*3} =\frac{20}{12}-\frac{3}{12} =\frac{20-3}{12} =\frac{17}{12} = 1\frac{5}{12}[/tex]
