A farmer need five men to clear his farm in 10 days how men will he need, if must finish clearing in 2 days if they work at the same rate

Answers

Answer:

1 person  

Step-by-step explanation:

It is given that a farmer wants 5 persons to complete a work of clearing his field in ten number of days.

We have to find out the number of persons required if the farmer needs to clear his field in 2 number of days.

Therefore according to the information given :

10 days = 5 persons

∴ 1 day = [tex]$\frac{5}{10}$[/tex] persons

So  2 days = [tex]$\frac{5}{10}\times 2$[/tex] persons

                 [tex]$=\frac{5}{5}$[/tex] person

                 = 1 person

The graph which best represents graph A thus option (A) is correct.

What is a graph?

A graph is a diametrical representation of any function between the dependent and independent variables.

The graph is easy to understand the behavior of the graph.

As per the given data and graphs.

A good scatter plot will be having a reasonable scale on the x and y-axis.

In the graph, The average pain level is in the range of 2 intervals and dosage in 50 intervals as the data also have close to this range.

Thus, graph A represents the best scatter plot.

Hence "The graph which best represents graph A".

Step-by-step explanation:

The function y=-16x^2+16x+32 represents the height in feet of a firework x seconds after it is launched

Answers

Answer:

36feet

Step-by-step explanation:

Since we are not asked what to find, we can as well find the maximum height reached by the rocket

At max height, velocity is zero

V = dy/dx = 0

dy/dx = -32x + 16

0 = -32x+16

32x = 16

x = 16/32

x = 0.5s

Get the maximum height

y = -16(0.5)^2+16(0.5) + 32

y = -4+8+32

y = 36feet

Hence the max height reached by the rocket is 36feet

okay so this is what i got very basic yup

help please!! I need an explanation

Answers

Step-by-step explanation:

A triangle's angles add up to be 180 degrees, so you can create an equation to be 180= 130+5x. (the 5x is 2x + 3x)

subtract 130 from both sides and get 50=5x, divide both sides by 5, x is equal to 10.

I'm not sure which angle is angle a, but if you substitute x with 10, you can find the measure of the angle, so if it's 2x, 2(10)=20 and if 3x, 3(10)=30

The total sum of angles in a triangle is 180°

2x + 3x + 130° = 180°

5x + 130° = 180°

5x = 180° - 130°

5x = 50°

x = 50° / 5

x = 10

Marcus borrowed 9000 from his bank to buy a car. The bank charged him a simple interest rate of 1.25%. By the time he paid back the money he had pad a total of 9281.25. How long did it take Marcus to pay back the money?

Answers

Answer:

2.5 years

Step-by-step explanation:

Given data

P=9000

r= 1.25%

A= 9281.25

The simple interest expression is given as

A=P(1+rt)

substitute

9281.25= 9000(1+0.0125*t)

9281.25=9000+112.5t

collect like terms

9281.25-9000=112.5t

281.25= 112.5t

t= 281.25/112.5

t= 2.5

Hence the time is 2.5 years

The raito of chocolate covered carmels to choclate corvered cherries in my vault is 5 to 2 if i have 84 choclate covereds cherries how many choclate covered caramels do i have

Answers

Answer: 1 have 210   chocolate covered caramels

Step-by-step explanation:

step 1

The  ratio  of chocolate covered caramels to chocolate covered cherries in my vault is 5 to 2 which can also be written as 5:2

But the number of chocolate covered cherries =84

Total ratio is given as 5+2 = 7

Step 2

such that the total number of chocolate i had  would be gotten from

Ratio of chocolate covered cherries/ total ratio x Total chocolates = Number of chocolate covered cherries. Let X = Total number of chocolates

2/7 x X = 84

x= 84 x 7 / 2 =294

Therefore The number of chocolate covered caramels= ratio of chocolate covered caramels/ total ratio x Total chocolates =

5/7 X 294= 210
