4 people can dig a hole in 3 hours. How long does it take 9 people.

ad-work [718]

Answer: 1 hour 20 minutes

<u>Step-by-step explanation:</u>

Let's figure out how long it would take 1 person to dig the hole and then divide that number by 9 (since they are sharing the workload).

$\dfrac{1}{4}x=3\qquad \implies \qquad x = 12\quad \text{It takes 12 hours for 1 person}\\\\\\\dfrac{12\ \text{(for 1 person)}}{9\ \text{(people)}}\quad =1\dfrac{1}{3}\quad =\large\boxed{1\ hour\ 20\ minutes}$

How do you find percent of a number mentally

olga55 [171]

It isn't easy really but you can always divide the number out. For example 50% of 200 is 100 by dividing 200 by 2 or 25% of 100 is 25 by dividing 100 by 4 since 25% is equivalent to 1/4

The diagram shows a solid formed by joining a hemisphere, of radius rcm, to a cylinder, of radius rcm and height hcm. The total

posledela

Answer:

Step-by-step explanation:

The total surface area of the sphere = 2πr²

Total surface area of the cylinder = 2πr²+2πrh

Total surface area of the solid = 4πr²+2πrh

r is the radius of the sphere and the cylinder

h is the height of the cylinder

Total surface area of the solid = 2πr(r+h)

If the total height of the solid is 18 cm, then r+h = 18cm

Given the Total surface area of the solid = 205π cm

205π = 2πr(r+h)

205π = 2πr(18)

205π = 36πr

205 = 36r

Divide both sides by 36

205/36 = 36r/36

r = 5.69cm

Since r+h = 18cm

5.69+h = 18

h = 18-5.69

h = 12.31cm

I forgot how to do this

adoni [48]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{1}}}}}$

Step-by-step explanation:

$\sf{ \frac{1}{2} \times 2}$

Multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term.

$\dashrightarrow{ \sf{ \frac{1 \times 2}{2 \times 1} }}$

$\dashrightarrow{ \sf{ \frac{2}{2} }}$

$\dashrightarrow{ \sf{1}}$

Or, You can simply reduce the fraction with 2, which results to 1.

Hope I helped!

Best regards! :D
