Andy had a snowball (a perfect sphere) with a radius of 3 \text{ cm}3 cm3, space, c, m. he wanted the snowball to be bigger, so

he spent 444 seconds packing more snow onto it. each second he spent packing, the snowball's radius increased by 0.25 \text{ cm}0.25 cm0, point, 25, space, c, m. what is the ratio of the current volume of the snowball to the original volume of the snowball? choose 1 answer:

The original volume is given by:
 V1 = (4/3) * (pi) * (r1 ^ 3)
 V1 = (4/3) * (3.14) * (3 ^ 3)
 V1 = 113.04 cm ^ 3
 The current volume is given by:
 V2 = (4/3) * (pi) * ((r1 + 0.25 * t) ^ 3)
 V2 = (4/3) * (3.14) * ((3 + 0.25 * 4) ^ 3)
 V2 = 267.9466667 cm ^ 3
 The relation of volumes is:
 V2 / V1 = 64/27
 Answer:
 
The ratio of the current volume of the snowball to the original volume of the snowball is:
 
V2 / V1 = 64/27

Answer:

x = 50.53 degrees

Step-by-step explanation:

Q 1

Find length of BD using the sine Rule:-

5.6 / sin 78 = BD / sin 50

BD =  5.6 * sin 50 / sin 78

BD = 4.386 cm

Now consider triangle BDC

m <  BDC = 180 - 78 = 102 degrees

Applying the sine Rule:-

9.3 / sin 102 =  4.386 / sin < BCD

sin BCD =  sin 102 * 4.386 / 9.3

sin < BCD = 0.4613

m < BCD = 27.47 degrees

So m < x =  180 - 102 - 27.47 degrres

=  50.53 degrees

What is 4/5+1/4 ? In fraction form.
snow_lady [41]
To answer this question you must make a come factor between the 2 fractions I believe the easiest way to do this is multiply the denominator or bottom number by the other one so 4*5 and 5*4 and what you do to the denominator you must do to the numerator so you would have to do 4*4 and 4*5 for the first fraction to get 16/20 and repeat on the other side 1*5 and 4*5 or 5/20 so the to fractions are 16/20+5/20 then add just the numerators 16+5=21 or 21/20 and simplify to 1/20

Answer:

  • The function is injective but nor surjective

Step-by-step explanation:

<u>We see that:</u>

  • f(x) = x³

<u>For any x₁ and x₂ ∈ N, </u>

  • f(x) = x₁³ = x₂³ ⇒ x₁ = x₂, both are natural numbers

It it confirmed one-to-one, hence it is injective

<u>Check the surjectivity:</u>

f(x) = y ∈ N

  • x³ = y
  • y = ∛x

<u>Let y = 2, then:</u>

  • 2 = x³
  • x = ∛2 ∉ N

Since x is not natural, the function is not surjective
