If every positive number has two square roots and you can find the length of the side of a square window by finding a square root of the area, why isthere only one answer for the length of a side?

Answers

because the 2 square roots are positive and negative
ex
squareroot of 4=2 or -2 since 2 time2=4 and -2 times -2=4
we normally use the principal root or the positive root since legnth in real life cannot be negative

Mrs. Smith decides to buy three sweaters and a pair of jeans. she had $120 in her wallet. if the price of jeans is $45,what is the highest possible price (p) of a sweater, if each sweater, if each sweater is the same price? write, solve, and graph the inequality.

Answers

Answer:

$3s+2j\leq $120$ . The sweaters cost $10 or less each. We graph it on a number line at 10 and use a filled in dot pointing towards zero for less than.

Step-by-step explanation:

Mrs. Smith buys 3 sweaters (represented by 3s) and 2 jeans (represented by 2j) for a total of at most $120. We don't know the total but we do know she couldn't spend more than $120.

We write $3s+2j\leq $120$ .

We know the jeans cost $45 each, so j=45. We substitute,

$3s+2(45)\leq $120\n3s+90\leq $120$

We solve for s by subtracting 90 to the other side and dividing the result by 3.

$3s+90-90\leq 120-90\n3s\leq 30\n(3s)/(3)\leq(30)/(3)$

$s\leq 10$ .

The sweaters cost $10 or less each.

The scale drawing of a poster design has the dimensions of 15 cm by 20 cm. The dimensions of the actual poster will be 60 cm by 80 cm. What is the scale of the drawing? 1/15 1/4 1/3 3/4

Answers

The scale is 1:4, as the poster's dimensions are 4 times larger than the scale drawing, which is represented by the second number in the ratio. To see this, you need to see that 15 goes into 60 four times and 20 goes into 80 four times. I hope this helped you!
