Answer:

Ext=2x

Int=7x

Int+ext=180

2x+7x=180

9x=180

x=20

Ext=2×20=40

No of sides =360/40

=9 sides.

I hope this helped you

15d^3+30d^2+30d/3d3 what is the answer if you divide the following
lawyer [7]
When you separate them
\frac{15d^{3} }{ {3d}^{3} }  +  \frac{30d^{2} }{ {3d}^{3} }  +  \frac{30d }{ {3d}^{3} }   = x
Solve them separately:
5 +  \frac{10}{d}  +  \frac{10}{ {d}^{2} }  = x
Remove the denominators:
5 + 10 {d}^{ - 1}  + 10 {d}^{ - 2}  = x
Find GCF (Greatest Common Factor):
5(1 + 2 {d}^{ - 1}  + 2 {d}^{ - 2} ) = x

Using the image above, if the density of the LEGO piece is 0.85 g/cm^3, what COULD be a possible measurement for the density of
grin007 [14]

The Lego is submerged under the oil and therefore, is more dense than the oil

The possible density of the oil is the option;

<u>0.79 g/cm³</u>

Reason:

Given:

The density of Lego = 0.85 g/cm³

Density of oil = Required

Solution:

The density of an object is the mass per unit volume it occupies

  • Density = \dfrac{Mass}{Volume}

Increase in density increases the mass a unit volume occupies, therefore, a

more dense object is heavier than a less dense object such that the less

dense object will float on a dense object

The oil is floating on the Lego, therefore, the Lego is more dense than the

oil, and we have;

  • Density of Lego > Density of oil

The density of Lego = 0.85 g/cm³

Therefore;

0.85 g/cm³ > Density of oil

From the given options, the option that has a density less than 0.85 g/cm³ is the the option 0.79 g/cm³

Therefore, the possible density of the oil is <u>0.79 g/cm³</u>

Find the interest generated if one invests $6000 for 9 years at 7% per annum with interest compounded monthly
marysya [2.9K]

Answer:

principle= 6000

time =9 years

rate = 7%

so,

compound interest = p((1+r/100)^t. -1)

= 6000((1+0.07)^9 -1)

=6000(1.84-1)

=6000*0.84

=5040
