What is the answer for the equation 3(5k+2) + 5= 3k-1
mina [271]

Answer:

  • 12k + 12.

Step-by-step explanation:

=> 3(5k + 2) + 5 = 3k - 1

=> 15k + 6 + 5 = 3k - 1

=> 15k + 11 - 3k + 1

=> 12k + 12

<u>Hence, correct answer is 12k + 12.</u>

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10.
Margaret [11]

Answer:

Question 1 ) Difference of Volume = 112.25 cm³

Question 2) Volume = 6400π feet³

Step-by-step explanation:

<h3>As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10. If the cans are currently 12 cm tall, 6 cm in diameter, and have a volume of 339.12 cm3, how much more will the new cans hold? Use 3.14 for π and round your answer to the nearest hundredth.</h3>

Diameter = 6 cm

Radius = 3 cm

Height = 12 cm

If we increase the dimension by 1.10, new dimesnions are:

Radius = 3 · 1.1 = 3.3 cm

Height = 12 · 1.1 = 13.2 cm

Volume = (Area)(Height) = (πr²)(Height)

Volume = (π)(3.3²)(13.2)

Volume = 451.37 cm³

Difference of Volume = 451.37 cm³ - 339.12 cm³

Difference of Volume = 112.25 cm³

<h3>The circumference of a redwood tree trunk is 16π ft, and it is 100 ft tall. What is the approximate volume of the redwood tree trunk? </h3>

Circumference = 2πr = 16π = 2π(8) feet

Radius = 8 feet

Volume = Volume = (Area)(Height) = (πr²)(Height)

Volume = (π)((8²)(100)

Volume = 6400π feet³

2. A university admitted 100 students who transferred from other institutions. Of these students, 34 transferred from two-year c
antoniya [11.8K]

Answer:

So probability will be 0.34

Step-by-step explanation:

We have given that a university admitted 100 students

In which 34 students are from two year community program

25 students are from private four year institution

And rest that is 100-34-25 = 41 students from public four year institutions

Number of ways for selecting two students from two year community program that is, from 34 students

=^{34}C_2

And the number of ways in selecting the 2 students from total student =^{100}C_2

So probability will be P=\frac{^{34}C_2}{^{100}C_2}=\frac{17}{50}=0.34
