60 ≥ 35 + 5t

-35 -35

25 ≥ 5t

5 5

t≤5

his mistake was that he used ≤ for at least instead of using ≥. so at end, when I solved, I saw that Sven should spend 5 minutes or less on each scale.

Henry received $500 for his birthday which he intends to invest in an account that pays simple interest at the rate of 12% per y

Mila [183]

Answer:

$560

Step-by-step explanation:

Given that :

Principal, P= $500

Interest rate, r = 12% per year

Amount in account after 1 year

Time = 1 year

Using the relation :

A = P(1 + rt)

A = final amount in account

A = $500(1 + 0.12(1))

A = $500(1 + 0.12)

A = $500(1.12)

A = $560

Use completing the square to find the value to add that makes x^2 - 12x a perfect square trinomial. Then write the expression as

yarga [219]

Answer:

Step-by-step explanation:

If you want to make

$x^2-12x$

into a perfect square binomial, take half the linear term, square it, then add it to both sides. Our linear term is 12. Half of 12 is 6, and 6 squared is 36.

The value that makes this a perfect square binomial is 36.

Writing the expression as a square of the binomial is:

$(x^2-12x+36)-->(x-6)^2$
