If John can mow the lawn in 2/3 of an hour and George can mow the lawn in 1 hour, how long will they take to mow the lawn togeth
snow_tiger [21]
This is esay to do when you realize the the speed of mowing is addtive. This is if John mows at 1 lawn / (2/3) hour and Gerge mows at 1 lawn /  1hour, the total speed of mowing is:

1 / (2/3) + 1 = 3/2 + 1 = 5/2

=> 5/2 of lawn per hour

Now, the time is calcualted as the amount of lawn divided by the speed:

1 lawn / (5/2 lawn/hour) = 2/5 hour.

Answer: 2/5 of an hour.

What are the domain and range of g(x)= √x-3?
Vera_Pavlovna [14]

Answer:

I guess, A is the wanted answer, but

A and D together are the really correct answer.

Step-by-step explanation:

if I understand this correctly, then

g(x) = sqrt(x - 3)

the domain of a function is the definition of all valid x (input) values.

the range of a function is the definition of all valid y (result) values.

well, the content (the arguments) of a square root cannot be negative (at least not while dealing with real numbers).

so, the answer options B and D are automatically out, because the domain contains values that would make the arguments of the square root negative.

I guess your teacher wants to focus only on the positive results of the square root, so A is the correct number.

BUT formally, without designated restrictions, a square root has always 2 solutions : a positive and a negative one.

because (-x)² = (x)² = x².

so, I would have to say that the really correct answer is

A + D, because the range contains both, the positive and the negative numbers.

Find the compound interest on 800 at 5% per annum for 2 years.​
Ludmilka [50]

Answer:

C = 82

Step-by-step explanation:

Given

R = 5\% -- Rate

P = 800 -- Principal

N = 2 -- Time

Required

Determine the compound interest

First, we calculate the Amount (A)

A = P(1 + R)^N

A = 800*(1 + 5\%)^2

Express % as decimal

A = 800*(1 + 0.05)^2

A = 800*(1.05)^2

A = 882

The compound interest (C) is then calculated as:

C = A -P i.e. Amount - Principal

C = 882 - 800

C = 82
