I’m confused can someone help and answer?

Answers

Answer 1

Answer: The radius is 5 inches, so r = 5
The height is 30 inches, so h = 30
We'll use pi = 3.14

Plug in the given values and then use PEMDAS to simplify
SA = Surface Area
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*5^2 + 2*3.14*5*30
SA = 2*3.14*25 + 2*3.14*5*30
SA = 6.28*25 + 6.28*150
SA = 157 + 942
SA = 1099

Answer: 1099

Answer 2

Answer: Just plug in the radius (5 in) for the 2 r's in your equation and the height (30 in) for the h in your equation.

SA=(2×3.14×5^2)+(2×3.14×5×30)
SS=(2×3.14×25)+(2×3.14×5×30)
SA=157+942
SA=1099 sq inches

models the percent, y, of an initial dose of medicine remaining in a patientbloodstream after x hours.

Based on the model, what percent of the initial amount of medicine will remain in the patient’s bloodstream after 10 hours? Round to the nearest whole percent.

Answers

The percentage of the initial amount of medicine that will remain in the patient’s bloodstream after 10 hours is, 17.7%.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

Since, The function that models the percentage, y, of an initial dose of medicine remaining in a patient's bloodstream after x hours is given as,

⇒ $y = 100 (0.5)^(x/4)$

Now, if we substitute the value of x as 10 because we need to find the percentage of medicine in the body after 10 hours.

Therefore, the value can be written as,

⇒ $y = 100 (0.5)^(x/4)$

Put x = 10;

⇒ $y = 100 (0.5)^(2.5)\n$

⇒ y = 17.677

⇒ y = 17.7

Thus, the percentage of the initial amount of medicine that will remain in the patient’s bloodstream after 10 hours is 17.7%.

16. 8h = p 17. 288 = 18h, 16 = h. She is making $16/h, so if she works 11 hours making that same amount, 11(16) = p, she would make $176. 18. I’m not sure. 19. 24/60 = 0.4 x 100 = 40%. 20. I’m assuming you already solved it? 21. 30 x 0.63 = 18.9 22. 81 x 0.6 = 48.6 31. 40 x 0.55 = 22. Since the item is on sale for 55% this means the price decreased by $22, so 40 - 22 = 18, so Nicole payed $18. 32. 881.95 x 1.65 = $1455.22 33. 48300 x 1.38 = 66654 34. 442 x 1.35 = $596.7 35. 221/130 = 1.7 x 100 = 170 % This is all I’ll do for now, I’ll probably come back to do more if someone hasn’t by then, but I hope this helped.

A company charges $211.25 for 5 trees and 15 shrubs, The company charges$15.25 more for a tree than a shrub. How much does each shrub cost?

Answers

First we make our formula: 5(t+15.25)+15t=211.25. (I use the same letter for both variables, but you have to make sure that whatever makes them different is in the formula) Then you work it like normal: 20t=135, T=6.75 so 1 shrub costs $6.75 Then substitute the answer in: 5(6.75+15.25)+15(6.75)=211.75 and check it. 1 tree is $110 :) hope this helps :)

A worm travels 1250 millimeters.how many meters did the worm travel?

Answers

we know that

$1\ meter=1,000\ millimeters$

by proportion

$(1)/(1,000)(m)/(mm) =(x)/(1,250)(m)/(mm) \n \n1,000*x=1,250\n \nx=1,250/1,000\n \nx=1.25\ m$

therefore

the answer is

$1.25\ m$

$m-meter\nmm-millimeter\n1m=1,000mm\to1mm=0.001m\n------------------\n\n1250mm=(1250\cdot0.001)m=1.250m=\boxed{1.25m}$

What is 428.6401 rounded to the nearest whole number ?

Answers

it would be 429 because 5 or more go next door for or less home is best. and 8 is greater then 5

Since you're rounding to the nearest whole number, you use the tenths place to determine how to round it. 6 ≥ 5 so the ones place is rounded up, making 429 your answer.
