It is known that a laptop company's average production is given by P(t) = (150t) / (3t+20), where

t is the time (in days). How many days will it take the company to produce 30 laptops?

Answers

Answer:

10 days

Step-by-step explanation:

Step one:

given that the expression for the company's average production is

[tex]P(t) = (150t) / (3t+20)[/tex]

Required:

t, when P=30

Step two:

substituting we have

30=150t/3t+20

cross multiply we have

30(3t+20)=150t

90t+600=150t

collect like terms

600=150t-90t

600=60t

divide through by 60

t=600/60

t=10 days

it will take the company 10 days

Please help 15 points available! What is the equation of the line that is perpendicular to y - 3 x = 2 and that passes through (6,1)?
y = 1/3x - 1
y = 1/3x + 3
y = -1/3x + 3
y = -1/3x - 1

Answers

Answer:

C) y = -1/3x + 3

Step-by-step explanation:

y - 3x = 2

  + 3x   + 3x

y = 3x + 2

find the reciprocal of the slope (3) which is -1/3 so -1/3 will be the slope for the perpendicular line

y = (-1/3)x + b

now find the y-intercept (b)

(6,1) x = 6   y = 1

y = (-1/3)x + b

1 = (-1/3)6 + b

1 = -2 + b

+2  +2

3 = b

y = (-1/3)x + 3

A new sidewalk will be 4 feet​ wide, 240 feet​ long, and filled to a depth of 9 inches ​(0.75 ​foot) with concrete. How many cubic yards of concrete are​ needed?

Answers

Answer: The number of cubic yards of concrete that are needed is 720.

Step-by-step explanation: The same formula for this type of shape stays the same: l*w*(h or d).

240 * 4 = 960

960 * 0.75 = 720

The amount of cubic yard of concrete needed is about 720 cubic foot

How to calculate the volume of box?

The formula for calculating the volume of the concrete is expressed as:

V = lwh

l is the length =240feet

w is the width = 4 feet

h is the depth = 0.75foot'

Determine the volume

V = 240 * 4 * 0.75
V = 720 cubic feet

Hence the amount of cubic yard of concrete needed is about 720 cubic foot

Answer:

D is your answer :D can you answer my question pleasseeeee it would be easy for you

HEEEEELP PLZ WILL GIVE 30 POINTS!!!!!!!!!!

Answers

Answer=

Well first we got to convert yards and feet into inches.

21 feet=252 inches

11 yards=396 inches

Alright so now that we have the inches needed we must find the cost for both Emily and Andy’s needed wire.

Emily:

We know how much it would cost for 200 inches, which is 8$.

15 inches adds a .60$ increase, which means that 5 inches is equivalent to .20$. By adding that to .60$ we get .80$ or the amount it would cost for 20 inches. We now know how much it would cost for 40 inches, 1.60$.

8+1.60=9.60 or how much it costs for 240 inches.

If it costs .80$ for 20 inches that means it costs .40$ for 10 inches.

9.60+.40=10

To find how much it costs for 2 inches we divide .40 by 5 which is .08.

10+.08=10.08$

Emily will spend 10.08$ for her needed wire.


Andy:

We know how much it would cost for 300 inches, which is 12$.

We also know how much it costs for 20 inches, which is .80$. So we multiply that by 4 to get how much it would cost for 80 inches.

.80*4=3.20

We then add that to the cost of 300 inches.

12+3.20=15.20

We know how much it would cost for 10 inches, which is .40$.

So we add that to the amount it would cost for 380 inches.

15.20+.40=15.60

Finally we know how much it costs for 2 inches, which is .08$. So we multiply that by 3 to find how much it costs for 6 inches.

.08*3=.24

We then add that to how much it would cost for 390 inches.

15.60+.24=15.84$

Andy will spend 15.84$ for his needed wire.

Answer:

Emily pays 10.40 and Andy pays 8 dollars

Step-by-step explanation:

So let's start with Emily, she need 21 feet of wire, so we convert this to inches so; [tex]1foot=12inches\\ 21feet=(12inches)*21=252inches[/tex]  but it's not listed on the tableSo we try to find the closest approximation to 252 inches which we get by adding 100 inches and 160 inches to get 260 inchesSo Emily will pay the cost of those to lengths so 100 inches cost 4.00 dollars and 160 inches costs 6.40 dollarsso she pays 4.00+6.40=10.40 dollarsNow for Andy we do much the same and find the inches in 11 yards[tex]1 yard=36inches\\ 11yards=(36inches)*11=396inches[/tex] this is also not listedSo we get the closest approximation, which is 4 of the 100 inch wires, so we get 400 inches costing 4*4.00=8 dollars
