Sam can mow a lawn in 40 minutes. Melissa can mow the same lawn in 80 minutes. How long does it take for both Sam and Melissa to
Sidana [21]

Answer:

It will take them both 24 minutes to mow the lawn if they are working together.

Step-by-step explanation:

Given that Sam can mow a lawn in 40 minutes, and Melissa can mow the same lawn in 80 minutes, to determine how long does it take for both Sam and Melissa to mow the lawn if they are working together, the following calculation must be performed:

1/40 + 1/60 = 1 / X

3X + 2X = 120

X = 120/5

X = 24

Thus, it will take them both 24 minutes to mow the lawn if they are working together.

Translate the sentence into an equation, then solve the
Oduvanchick [21]

Answer:

The equation is: \frac{x-7}{5} = 13 and the number is 72.

Step-by-step explanation:

We have to use mathematical notation to convert the given statement into an equation. As we don't know the exact value of number, we have to use a variable in place of the number.

Let x be the required number then

"A number decreased by 7"

x-7

"and then  divided by 5"

\frac{x-7}{5}

" is 13."

\frac{x-7}{5} = 13

For solving, multiplying both sides of equation by "5"

\frac{x-7}{5} * 5 = 13*5\\x-7 = 65

Adding 7 on both sides of equation

x-7+7 = 65+7\\x = 72

Hence,

The equation is: \frac{x-7}{5} = 13 and the number is 72.

g If A and B are disjoint events, with P( A) = 0.20 and P( B) = 0.30. Then P( A and B) is: a. .00 b. .10 c. .50 d. 0.06
Lostsunrise [7]

Answer: A) 0

P(A and B) = 0 when events A and B are disjoint, aka mutually exclusive.

We say that two events are mutually exclusive if they cannot happen at the same time. An example would be flipping a coin to have it land on heads and tails at the same time.
