A cylinder has a base with a radius of 7 cm and a volume of 615.44 cm3. Use 3.14 for π . Write and solve an equation to find the height of the cylinder.

Answers

Answer:

The height is 4 cm

Step-by-step explanation:

V = (pie) x radius² x height

615.44 cm³ = (3.14) x 7² x h

h = 615.44 cm³/(3.14 x 49)

h = 615.44 cm³/153.86

h = 4 cm²

Given the series 2+ 6 + 18+
*
use an appropriate formula to find S12.

Please put full solution.

Answers

Answer: Samsung Galaxy S12

Answer:

S₁₂ = 531440

Step-by-step explanation:

There is a common ratio between consecutive terms, that is

r = 6 ÷ 2 = 18 ÷ 6 = 3

This indicates the sequence is geometric with sum to n terms

[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex] ( r ≠ 1 )

where a is the first term and r the common ratio

Here a = 2 and r = 3 , then

S₁₂ = [tex]\frac{2(3^{12}-1) }{3-1}[/tex]

= [tex]\frac{2(531441-1)}{2}[/tex]

= 531441 - 1

= 531440

A Speedboat increases in speed uniformly from 20m/s to 30m/s for 12.2 s. What is the acceleration of the speedboat?

Answers

Answer:

0.82 m/s^2

Step-by-step explanation:

Given data

initial velocity=20m/s

Final velocity= 30m/s

Time = 12.2s

Applying the formula

a= v-u/t

a= 30-20/12.2

a= 10/12.2

a= 0.819

a=0.82 m/s^2

Dan bought a new computer for $900. Each year, the value of the computer decreased by 25% of the previous year's value. At this rate, what can Dan expect the approximate value of the computer to be after 8 years?

Answers

Answer:

$90

Step-by-step explanation:

Given data

Price= $900

Rate= 25%

Time= 8 years

Let us apply the compounding formula

A= P(1-r)^t >>>>note that the negative sign is because of the depreciation

substitute

A= 900(1-0.25)^8

A= 900(0.75)^8

A= 900*0.100

A= $90

Hence the value of the car after 8 years will be $90

Central Fencing has been hired to fence the perimeter of a rectangular field. The length of the field is 42 - W feet, where W is the width of the field, and the area of the field must be more than 432 square feet. Find the bounds on the width of the field.

Answers

Answer:

10.3 is the width

Step-by-step explanation:

set up an equation

42w=432

divided both sides by 42

W=10.2857142857

to rounded it to nearest tenth it will be 10.3

to check your answer multiply 10.3 by 42 it will be 432

check check

Answer:

18 ≤ w ≤ 24

Step-by-step explanation:

A = l * w

A ≥ 432 sq ft.

l = 42 - w

432 ≤ (42 - w) (w)

432 ≤ -w² + 42w

w² - 42w ≥ 432

Substitute values for w

w = 18

w = 24

X = ?

Answers

Answer:

x = 3

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

[tex]\frac{1}{2}[/tex] (3x + 3 + 4x + 2) = 13

[tex]\frac{1}{2}[/tex] (7x + 5) = 13 ( multiply both sides by 2 )

7x + 5 = 26 ( subtract 5 from both sides )

7x = 21 ( divide both sides by 7 )

But seorita means different things to different people.For my friends Mireya and Sarita, who turned fifteen last summer, seorita means wearing lipstick, which when I put it on is sticky and messy, like strawberry jam on my lips.For Mami, seorita means making me try on high-heeled shoes two inches high and meant to break my neck.For Mamis sisters, my tas Maritza and Beln, who live in Mexico, seorita means measuring me, turning me this way and that as they fit me for the floral dresses they cheerfully stitch together on their sewing machines.For the aunts, seorita also means insisting I wear pantyhose, the cruel invention that makes my thick, trunk-like thighs into bulging sausages.When my tas are done dressing me up like a big Mexican Barbie doll, I look at myself in the mirror. Mami stands behind me as I pull at the starched flowered fabric and argue with Mamis reflection.Why do I have to wear this stuff? This is your style, not mine! I like jeans and tennis shoes. Why cant I just dress like a normal teenager? En los Estados Unidos, girls dont dress up like muecas.Seoritas dont talk back to their mothers, Mami warns. When my aunts arent looking, she gives me a tiny pinch, like a bee sting on the inside of my upper arm. Seoritas know when to be quiet and let their elders make the decisions.For my father, seorita means he has to be a guard dog when boys are around. According to my parents, I wont be allowed to date until I graduate from high school.Thats fine with me. I have better things to do than think about boys like prepare for my future. I want to be the first one in our family to earn a college degree.For my sisters, seorita means having someone to worship: it is the wonder of seeing their oldest sister looking like Cinderella on her way to the ball.But for me, seorita means melancola: settling into sadness. It is the end of wild laughter. The end of chewing bubble gum and giggling over nothing with my friends at the movies, our feet up on the backs of the theater seats.Seorita is very boring when we go to a fancy restaurant decorated with Christmas lights for the upcoming Posadas. We sit properly, Papi, Mami, and I, quietly celebrating my fifteenth birthday with due etiquette because Im trying my best to be a good daughter and accept the clipping of my wings, the taming of my heart.Being a seorita is not as much fun as Id expected it to be. It means composure and dignity.Seorita is a nia, the girl I used to be, who has lost her voice. A typical laboratory centrifuge rotates at 4000 rpm.
