Answer:

FE = 30°

Step-by-step explanation:

arc FGC = arc FG + arc GB + arc BC

220° = 90° + arc GB + 70° . . substitute known values

60° = arc GB . . . . . . . . . . . . . subtract 160°

__

External angle A is half the difference of arcs EG and GB:

30° = (1/2)(arc FE +90° -60°) . . . substitute known values

60° = arc FE + 30° . . . . . . . . . . . multiply by 2 and simplify

30° = arc FE . . . . . . subtract 30°

_____

The key to this problem is the relationship between external angle A and the measures of the arcs it subtends.

What is B^y=x in logarithmic form?
Gala2k [10]

Answer:

The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base. In general, y = logb x is read, “y equals log to the base b of x,” or more simply, “y equals log base b of x.” As with exponential functions, b > 0 and b ≠ 1

laila [671]

Answer:

\displaystyle 10 = ax + bx \rightarrow x = \frac{10}{a + b}

General Formulas and Concepts:

<u>Pre-Algebra</u>

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Algebra I</u>

  • Factoring

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

\displaystyle 10 = ax + bx

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Factor:                                                                                                               \displaystyle 10 = ax + bx \rightarrow 10 = x(a + b)
  2. [Division Property of Equality] Divide a + b on both sides:                           \displaystyle 10 = ax + bx \rightarrow x = \frac{10}{a + b}

I need someone who can explain how to do this so I can understand please ASAP!!
Debora [2.8K]

Answer:

5

Step-by-step explanation:

An area is just a number squared, so we need to find the square root of the area.

Square root of 25 = 5

So each edge is 5 feet.

Hope this helps :)

If two 6-sided dice are rolled what is the probability that both numbers will be even?
Tamiku [17]
The probability of one dice rolling an even number is 1/2 as half the numbers are even. Since the events are independent, and there are 2 dice, we need to square 1/2 to get 1/4, assuming they are both fair dice

Tonya runs 8 kilometers in 60 minutes.At this rate,how long it take her to run 2 kilometers
Setler79 [48]
15 Minutes

You have 8 km in an hour.

Divide all that by two and you'll have 4 km in 30 mins.

Then divide by two again to end up with 2 km in 15 mins.

You could alternatively divide by four from the beginning, but I find this easier.
