PLEASE HELP! Is my answer correct?
Oxana [17]

We know angle P is 90 degrees because of Thales Theorem, and angle N is 60 degrees. Because the angles in a triangle have to add up to 180 degrees, angle PMN has to be 30 degrees.

Angle QMO is half of angle PMN, so it's 15 degrees. Angle MQO is equal to angle QMO because the radii make Triangle OQM isosceles, so angle MQO is 15 degrees.

Question 5 (1 point)<br><br> Write an equivalent expression for (m + 4n) - 2.5m
aliina [53]

Answer:

-1.5m + 4n is the equivalent expression

Step-by-step explanation:

To find the equivalent expression, we combine the like terms.

We are given the following expression:

m + 4n - 2.5m

Combining the like terms:

m - 2.5m + 4n

-1.5m + 4n is the equivalent expression

On the Richter scale, the magnitude, M, of an earthquake is given by M= 2/3logE/Eo, where E is the energy released by the earthq
Ivahew [28]

Answer:

See below

Step-by-step explanation:

Part A

<em><u>Formula</u></em>

M = 2/3 * log(E/Eo)

<em><u>Givens</u></em>

M = ??

E = 2 * 10^15 joules

Eo = 10^4.4

<em><u>Solution</u></em>

M = (2/3) * log(2 * 10^15 / 10^4.4)

M = (2/3 ) log (7.96 * 10 ^ 11)

M = (2/3) * 11.901

M = 7.934

Part B

What the question is saying is that E/Eo = 10000

You don't have to figure out exact values.

M = 2/3 * log(10000)

M = 2/3 * 4

M = 8/3 or 2 2/3 or 2.66667

If you have choices, please list them.

Need help asap The answer is 100 or 126​
Serga [27]

Answer:

The surface area of the cone is 126π cm².

Step-by-step explanation:

The surface area of a cone can be found using this formula:

  • \text{SA} = \pi r ^2+\pi r l
  • where r = radius and l = slant height

In this problem, we are told that the cone has a radius of 9 cm and a slant height of 5 cm.

Substitute these values into the formula for the surface area of a cone.

  • \text{SA}= \pi (9)^2+ \pi(9)(5)\\
  • \text{SA}= \pi (81)+ \pi(45)
  • \text{SA}= 126 \pi

The surface area of the right cone is 126 π cm².
