Convert any mixed numbers to fractions.

Then your initial equation becomes:

41×178

Applying the fractions formula for multiplication,

=4×171×8

=688

Simplifying 68/8, the answer is

=812

Pls help ;-;<br> Solve for m∠B and m∠C in the parallelogram.<br><br> m∠B = ?°<br> m∠C = ?°

Ivahew [28]

Answer:

m∠B = 121

m∠C = 59

Step-by-step explanation:

Angle B:

$(10x - 19) = (7x+23)\\10x+(- 19+19) = 7x+(23+19)\\10x=7x+42\\(10x-7x) = (7x-7x)+42\\3x = 42\\3x/3 = 42/3\\x = 14$

10(14)-19 = 140-19 = 121

Angle C:

(121)2 = 242

360-242 = 118

118/2 = 59

A stuntman jumping off a 20-m-High building is modeled by the equation h=20-5t^2, where t is the same in seconds. A high-speed c

Alchen [17]

Answer: $1\leq t\leq \sqrt{2}$

Step-by-step explanation:

1. You know that the high-speed camera is ready to film him between 15 meters and 10 meters above the ground.

2. The problem gives you the following equation:

$h=20-5t^{2}$

3. Therefore, you must calculate the time when $h=15$ and when $h=10$ , as following:

$h=15\\15=20-5t^{2}\\5t^{2}=5\\t=\sqrt{1}\\t=1$

$h=10\\10=20-5t^{2}\\5t^{2}=10\\t=\sqrt{2}$

4. Therefore, the answer is:

$1\leq t\leq \sqrt{2}$

Solve Fast Please!!!!!!!!!!!!!! ok thanks, Bye (2x−5)^2−.5x<(2x−1)(2x+1)−15

Andrews [41]

Keep these rules in mind:

(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
(a + b)(a - b) = a² - b²

Firstly, solve the exponent and multiplication:

$4x^2-20x+25-0.5x$

Next, combine like terms:

$4x^2-20.5x+25$

Next, subtract 4x² on both sides:

$-20.5x+25$

Next, subtract 25 on both sides:

$-20.5x$

Lastly, divide both sides by -20.5. And since you are dividing by a <u>negative</u>, flip the inequality sign:

$x>2$

<u>Your answer is x > 2.</u>
