Answer:

Yes

Step-by-step explanation:

You can take 1/2 and find a common denominator if this helps you.

We will multiply 1/2 by 25/25 because 25/25 equals 1 so you get the same amount just with a different numerator and denominator. So you get 25/50 and then you compare. 31/50 > 25/50

Papessa [141]

Answer:

The inequality expression are $5x + 10y\geq\$70 \ and \ x + y \leq 10 hours$

Step-by-step explanation:

Given:

Number of hours for babysitting for a week = $x \ hours$

Charge for baby sitting = 5$ an hour

Money earned for babysitting in x hours = $5x$

Number of hours for cashier for a week = $y \ hours$

Charge for Cashier = $10 an hour

Money earned for Cashier in y hours = $10y$

He wants to earn at least 70$.

Hence the expression becomes.

$5x + 10y \geq 70 \$$

Also,

He can’t work any more than 10 hours a week

Hence the expression becomes.

$x + y < 10 \ hours$

Inequality equation for the given statements are:

The inequality expression are $5x + 10y\geq\$70 \ and \ x + y \leq 10 hours$

The function, f(t), represents the distance from sea level, in meters, of a submarine after t minutes.

topjm [15]

The domain for f(t) is all of the numbers t for which f(t) is defined.

In other words, its all of the numbers that t minutes can be and still make sense in the function.

f(t) is distance from sea level as a function of time. It does not make sense to have negative time, so t must be 0 or a positive number. t does not necessarily have to be an integer (a whole number), since you can have time values like half a minute.
