Blizzard [7]

Answer:

Step-by-step explanation:

7)Fraction of apple pie after eaten by Jeremy = 1 - (1/3) = 2/3

Fraction of pie eaten by  Sara

= \dfrac{1}{4}*\dfrac{2}{3} \\\\\\= \dfrac{1}{2*3}\\\\=\dfrac{1}{6}

8)

Fraction \ of \ allowence \ spent \ on \ magazines = \dfrac{5}{8}*\dfrac{2}{3}=\dfrac{5*1}{4*3}=\dfrac{5}{12}

Fraction left = 1 -\dfrac{5}{12}=\dfrac{12}{12}-\dfrac{5}{12}=\dfrac{12-5}{12}=\dfrac{7}{12}

Please answer this question!! &lt;3 &lt;4 &lt;5 &lt;6 &lt;9
omeli [17]

The correct answer is option C which is the angle LMO is 50°

<h3>What is trigonometry?</h3>

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.

Given that:-

∠O = 70°

∠L = 60°

∠LMO =?

As we know that the sum of the three angles are 180 degree applying this relation:-

∠LOM + ∠OLM  + ∠LMO = 180

70 + 60 +  ∠LMO = 180

∠LMO = 180 - 70 - 60 = 50

Therefore the correct answer is option C which is the angle LMO is 50°

The volume of the cone shown below is 108pie cm^3. What is the value of H?
saw5 [17]

Answer:

h = 4cm

Step-by-step explanation:

Diameter = 18cm

Radius = Diameter/2 = 18/2 = 9cm

V = 1/3*pi*r^2*h

We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.

So,

108 pi = 1/3*pi*9^2*h

108 pi = (81pi*h)/3

multiply 3 from both side

108pi*3 = (81pi*h)/3 *3

324pi = 81pi*h

Now divide the 81pi from both side

324pi/81pi = (81pi*h)/81pi

4 = h

So the height is 4cm
