Hi,

Solving:

\frac{2 {y}^{2} - 6y - 20}{4y + 12} \div \frac{ {y}^{2} + 5y + 6}{ 3 {y}^{2} + 18y + 27 } \\ \frac{2 {y}^{2} - 6y - 20}{4y + 12} \div \frac{3 {y}^{2} + 18y + 27 }{{y}^{2} + 5y + 6} \\ \frac{2( {y}^{2} - 3y - 10)}{4y + 12} \div \frac{3 {y}^{2} + 18y + 27}{ {y}^{2} + 5y + 6} \\ \frac{2( {y}^{2} - 3y - 10}{2(2y + 6)} \times \frac{3 {y}^{2} + 18y + 27}{ {y}^{2} + 5y + 6} \\ \frac{ \not2( {y}^{2} - 3y - 10) }{ \not2(2y + 6)} \times \frac{3( {y}^{2} + 6y + 9) }{ {y}^{2} + 5y + 6} \\ \frac{ {y}^{2} + 2y - 5y - 10 }{2(y + 3)} \times \frac{3( {y}^{2} + 6y + 9) }{ {y}^{2} + 3y + 2y + 6} \\ \frac{y \times (y + 2) - 5(y + 2)}{2(y + 3)} \times \frac{3(y + 3)^{2} }{y \times (y + 3) + 2(y + 3)} \\ \frac{ (y + 2) \times (y - 5)}{2(y + 3)} \times \frac{3(y + 3)^{2} }{(y + 3) \times (y + 2)} \\ \frac{y - 5}{2(y + 3)} \times 3(y + 3) \\ \frac{y - 5}{2} \times 3 = \frac{3y - 15}{2} \: \: \: \: \: \: \: \: \: \: \: \: result

Angle Q = 85° Determine angle O.
kkurt [141]

Answer:

∠O = 95°

Step-by-step explanation:

since ∠Q = 85°, arc NOP = 2(85°) = 170°

arc PQN = 360° - arc NOP

arc PQN = 360° - 170° = 190°

∠O = 1/2(arc PQN) = 1/2(190°) = 95°

Alice works at a health care facility. She has measured the hemoglobin levels of 200 people. The data follows a normal distribut
rewona [7]
Since the data follows a normal distribution, the 68-95-97 rule can be used to describe the number of people falling under N standard deviations from the mean. Since the standard deviation is 1, hemoglobin levels of 13 -15 g/dL contains 68% of the sample, or 136 people. This means the 32 people have less than 13 g/dL and 32 people have more than 15 g/dL.

Calculate the distance between the points M=(-1,-1) and P=(2, -8) in the coordinate plane. Give an exact answer (not a decimal a
pantera1 [17]
This is a Pythagorean Theorem problem. 3^2 + 7^2 = 58. C^2 = 58. C = 7.6157 (exact)

There is no exact answer for this. The closest we can get to 58 is 7.6157, which would leave us at 57.9988. So the approximate value is 7.6, but if you need the closest answer, it’s 7.6157.
