Answer:

Here is a proof

Angle DEF = angle ABC

A transversal cutting two parallel lines makes alternate exterior angles equal

Sum of measures of angles 1 and 2 = 50° + 48° = 98° = measure of angle DEF = measure of angle ABC

But since s bisects angle ABC, then angle 4 = 98 / 2 = 49°

But angles 3 and 4 are vertical angles....therefore.... measure of angle 3 = 49°

Step-by-step explanation:

To the nearest dollar, the average tuition at a public four−year college was $3088 in 1997 and $3292 in 2000. Find, to the nea

Delicious77 [7]

the fees in 1997 was $3088

fees in 2000 was $3292

average rate of increase= (3292-3088)/(2000-1997) = 204/3=68

so average rate of increase is $68 per year

What pattern do you see in the powers of 4?

Over [174]

All of them are even numbers. You will not find a power of 4 that is an odd number. Also, all of the numbers have a 4 or a 6 or both. For example,
4^3= 64

4^8= <span>65536

I hope this helps:)</span>

Find the quotient of 4.13 x 10^-8 and 0.04 x 10^5. In two or more complete sentences, explain each step in your calculations.Inc

poizon [28]

we know that

Quotient is the number resulting from the division of one quantity by another

Let

x--------> the first quantity

y------> the second quantity

q------> the quotient

$q=\frac{x}{y}$ -------> equation 1

in this problem

$x=4.13*10^{-8} \\ y= 0.04*10^{5}$

Substitute the values in the equation 1

$q=\frac{4.13*10^{-8}}{0.04*10^{5}}$

Simplify

$q=\frac{4.13*10^{-8}}{0.04*10^{5}}=\frac{4.13}{0.04}*10^{-8}*10^{-5}=\frac{4.13}{0.04}*10^{-13}\\ \\q=103.25*10^{-13}\\ \\q= (1.0325*10^{2})*10^{-13}\\ \\q= 1.0325*10^{-11}$

therefore

<u>the answer is</u>

The quotient is equal to $1.0325*10^{-11}$
