Nikola has received two job offers. The first is for an online company that pays $20 per hour. The work is interesting and lets
max2010maxim [7]

Answer: Context

I get how Nikolai is working at home and will be getting paid $20 but despite the $25 being at a factory and is repetitive, here is a little word from experience. The $25 is a start-off which is pretty good and it won't always be at a factory. If Nikolai is working hard and repetitive, he will be promoted to the fact where he will be paid more and work at home time-to-time. The $20 one, however, is a work-at-home type and since there is children, the house will have to be quiet during calls and what-not.

The area of the base of the oblique pentagonal pyramid is 50 cm2 and the distance from the apex to the center of the pentagon is
kirza4 [7]

Answer:

\text{Height is }6\sqrt2cm

\text{The volume is }100\sqrt2cm^3    

Step-by-step explanation:

Given the area of the base of the oblique pentagonal pyramid is 50 cm^2 and the distance from the apex to the center of the pentagon is 6 cm. The measure of ∠ACB is 45°.

we know that

ABC is a right triangle

∠ACB=45°

AC=hypotenuse------> 6 cm

\sin 45^{\circ}=\frac{AB}{AC}

AB=AC\times \sin 45

AB=\frac{6}{\sqrt2}

AB=3\sqrt2

\text{Height is }6\sqrt2cm

Now, volume of pyramid

\text{Volume of the pyramid=}\frac{1}{3}\times \text{Area of the base}\times height

Area of the base=50 cm²

Height=6\sqrt2 cm

so, \text{volume of the pyramid=}\frac{1}{3}\times 50\times 6\sqrt2=100\sqrt2cm^3

\text{the volume is }100\sqrt2cm^3

Apply the distributive property and the greatest common factor to write an equivalent expression.
myrzilka [38]
You can take out a 12 from each factor as they can both be divided by 12. That leaves you with 12(5x-2) if you applied the distribution property, you'd end up with the same answer you started with.

AnnZ [28]

Answer:

Part A: 4/9

Part B: 12 students

Step-by-step explanation:

27 * 0.44444444 = 12 (this is the number of students who preferred snowboarding). So the fraction would be 12/27, which simplifies to 4/9.
