If it is irrational, you won’t be able to write it as a ratio.
Also, if you are able to write the fraction as x/y then it is, in fact, rational.

The value of the expression when t-32 degrees is what degrees

GaryK [48]

Complete Question:

The temperature doubled. Evaluate when t = 32 degrees.

The value of the expression when t = 32 degrees is degrees

Answer:

64 degrees

Step-by-step explanation:

Given

$t = 32$

Required

Determine the value of t when it doubles

To do this, we simply multiply the current temperature by 2.

So:

$t = 32$ becomes

$t = 32 * 2$

$t = 64$

Hence, the temperature when it doubles is 64 degrees

HELP...... rewrite the equation by completing the square. x ^2 +10x+16=0

Sonbull [250]

Answer:

$(x+5)^{2} = 9$

Step-by-step explanation:

To complete the square you need to add $\frac{b}{2}^{2}$ to both sides. (Parenthesis around b/2)

b = 10

b/2 = 5

(b/2)^2 = 25

$x^{2}$ +10x + 16 = 0

subtract 16 to both sides

$x^{2}$ + 10x = -16

add 25 to both sides

$x^{2}$ +10x + 25 = 9

Perfect Square Trinomial Factoring

$(x+5)^{2}$ = 9

You want to wrap a gift shaped like the regular triangular prism shown. How many square inches of wrapping paper do you need to

Maslowich

You would need 438.45 inches of wrapping paper to cover the triangular prism completely. But since you can’t really cut the paper to that exact decimal you would round to 439 inches. Don’t forget to cube your answer since it’s area. Final answer should look like 429in.2
