Answer:

b has 79,775 million

a has 241,275 million

Step-by-step explanation:

a has more than b

b+161,500 is a

b=b

b+b+161,500=321,050

2b=321,050-161,500

2b=159,550

b=159,550/2

b=79,775

a=b+161,500

a=79,775+161,500

a=241,275

The following equation is given.
SashulF [63]

5x² - 9x + 45 = 0

Δ = b² - 4.a.c

Δ = (-9)² - 4 . 5 . 45

Δ = 81 - 4. 5 . 45

Δ = -819

There's no real root.

For an outdoor concert by the city​ orchestra, concert organizers estimate that 16 comma 000 people will attend if it is not rai
Sladkaya [172]

Answer:  13300

========================================

Work Shown:

A = event that it rains

B = event that it does not rain

P(A) = 0.30

P(B) = 1-P(A) = 1-0.30 = 0.70

Multiply the attendance figures with their corresponding probabilities

  • if it rains, then 7000*P(A) = 7000*0.30 = 2100
  • if it doesn't rain, then 16000*P(B) = 16000*0.70 = 11200

Add up the results: 2100+11200 = 13300

This is the expected value. This is basically the average based on the probabilities. The average is more tilted toward the higher end of the spectrum (closer to 16000 than it is to 7000) because there is a higher chance that it does not rain.

Manuel bought a balloon (that is a perfect sphere) with a radius of 2 \text{ cm}2 cm2, space, c, m. He wanted his balloon to be
jonny [76]
The original volume of the balloon is given by:
 V1 = (4/3) * (pi) * (r ^ 3)
 Where,
 r: radius of the sphere.
 Substituting values:
 V1 = (4/3) * (pi) * (1 ^ 3)
 V1 = (4/3) * (pi) * (1)
 Then, the volume of the current sphere is:
 V2 = (4/3) * (pi) * ((1 + 2 * (1)) ^ 3)
 V2 = (4/3) * (pi) * ((1 + 2) ^ 3)
 V2 = (4/3) * (pi) * ((3) ^ 3)
 V2 = (4/3) * (pi) * (27)
 The relation of volumes is:
 V2 / V1 = ((4/3) * (pi) * (27)) / ((4/3) * (pi) * (1))
 V2 / V1 = 27/1
 Answer:
 
The ratio of the current volume of the balloon to the original volume of the balloon is:
 
27: 1
