A square box lid has an area of 50 square inches. Which is the best estimate of the length of one side?

PtichkaEL [24]

Answer: 7.1 inches

Step-by-step explanation:

The area of a square is simply the square of one of its length. Therefore since we are informed that the area of the square box is given as 50 inches².

Then the best estimate of the length of one side will be the square root of 50 which will be:

= ✓50

the number of words Sylvia types varies directly with the amount of time she spends typing. If Sylvia types 100 words in 2.5 min

Eddi Din [679]

Answer:

600 words

Step-by-step explanation:

To solve this problem, we need to cross multiply. Lets input the values (100, 2.5, 5) as shown below:

$\frac{100}{2.5}=\frac{x}{15}$

Next we cross multiply. We multiply 2.5 and x, and we multiply 100 and 15.

$2.5(x)=2.5x$

$100(15)=1,500$

Now, lets put the values above back into the equation:

$2.5x=1,500$

Our next step is to divide 1,500 by 2.5 to get <em>x</em> by itself.

$x=\frac{1,500}{2.5}$

$x=600$

Sylvia can type 600 words in 15 minutes.
