Which is larger, 2 wholes or 9/4?

Inga [223]

answer:

9/4

step-by-step explanation:

2 as a fraction is 8/4

seeing as how 9/4>8/4

or you could convert 9/4 to a decimal which is 2.25 and 2.25>2

the larger number is 9/4

good luck :)

hopefully, this helps

have a good day !!

1) Given: mLHE=84°<br><br>Find: m∠EYL. <br><br>2)Given: m∠EYL=72°<br>Find: m arc EHL, m arc LVE

SCORPION-xisa [38]

Answer:

Part 1) The measure of angle EYL is $96\°$

Part 2) The measure of arc EHL is $108\°$ and the measure of arc LVE is $252\°$

Step-by-step explanation:

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

Part 1)

Let

x------> the measure of arc LHE

y----> the measure of arc LVE

we know that

$x+y=360\°$

$x=84\°$

Find the value of y

$y=360\°-84\°=276\°$

<em>Find the measure of angle EYL</em>

$m$

substitute the values

$m$

Part 2)

Let

x------> the measure of arc EHL

y----> the measure of arc LVE

we know that

$x+y=360\°$

$x=360\°-y$ -----> equation A

$m$

substitute

$72\°=\frac{1}{2} (y-x)$

$144\°=(y-x)$

$x=y-144\°$ --------> equation B

equate equation A and equation B and solve for y

$360\°-y=y-144\°$

$2y=360\°+144\°$

$2y=504\°$

$y=252\°$

Find the value of x

$x=252\°-144\°=108\°$

therefore

The measure of arc EHL is $108\°$

The measure of arc LVE is $252\°$

evaluate f(6) and f(6.1) and use the results to approximate f '(6). (round your answer to one decimal place.) f(x) = x(5 − x)

mote1985 [20]

F(6) = 6(5 - 6) = 6(-1) = -6
f(6.1) = 6.1(5 - 6.1) = 6.1(-1.1) = -6.71

f'(6) ≈ (-6.71 - (-6))/(6.1 - 6) = -0.71/0.1 = -7.1
