Answer:

Step-by-step explanation:

The difference between each term is six and the numbers are increasing so the only one that is in the correct format, which is an = a1 + (n-1)d, is B

Basically, the equator is like the x-axis of the world and the prime meridian is like the y-axis. You locate places by distances from these lines.

In the circle below, O is the center and mĞ= 128° What is the measure of angle HIG?

Paul [167]

Answer:

26 degrees.

Step-by-step explanation:

From the figure it is clear that HI is the diameter and $acr(GI)=128^{\circ}$ . So,

$\angle GOI=128^{\circ}$

$\angle GOI+\angle GOH=180^{\circ}$ (linear pair)

$128^{\circ}+\angle GOH=180^{\circ}$

$\angle GOH=180^{\circ}-128^{\circ}$

$\angle GOH=52^{\circ}$

Using central angle theorem of a circle, we get

$\angle HIG=\dfrac{\angle GOH}{2}$

$\angle HIG=\dfrac{52^{\circ}}{2}$

$\angle HIG=26^{\circ}$

Therefore, the measure of angle HIG is 26 degrees.

I REALLY NEED HELP!!! this is graded and plzzzz no links!!!!!

8 x 6 = 48 (regularly you’d divide by two but this is on both sides so we’ll leave it)
4 x 10 = 40 / 2 = 20
6 x 4 = 24 / 2 = 12
8 x 4 = 32 / 2 = 16
48 + 20 + 12 + 16 = 96
hope that helps! message me with any questions on other problems.

A 440.0-volt electric heater draws 10.0 amperes of current. according to Ohms law,what is the resistenace of the heater

Zanzabum

Answer:

The resistance of the heater is 44 ohms.

Step-by-step explanation:

Given that,

Voltage of electric heater, V = 440 volts

Current drawn by the heater, I = 10 A

We need to find the resistance of the heater. It is a case of Ohm's law. Its mathematical form is given by :

$V=IR$

R is resistance of the heater

$R=\dfrac{V}{I}\\\\R=\dfrac{440\ V}{10\ A}\\\\R=44\ \Omega$

So, the resistance of the heater is 44 ohms. Hence, this is the required solution.
