Alexa worked 30 hours last week and earned $450. Her pay has now been increased by 20%. Which equation describes her new rate of

vesna_86 [32]

Answer:

$p=18h$

$p=\dfrac{450}{30}\cdot 1.2\cdot h$

Step-by-step explanation:

If Alexa worked 30 hours last week and earned $450, then her hourly payment is

$\dfrac{\$450}{30}=\$15.$

Her payment has now been increased by 20%, so her hourly payment becomes

$\$15\cdot 1.2=\$18.$

If she worked h hours, then she earned $\$18h.$ If her new payment is p, then

$p=18h$

$p=\dfrac{450}{30}\cdot 1.2\cdot h.$

In circle D, if the measure of arc Gec is 230 , what is the measure of minor arc GFC

BabaBlast [244]

Answer:

The measure of minor arc GFC is $130\°$

Step-by-step explanation:

we know that

In a circle the sum of the major arc plus the minor arc is equal to 360 degrees

see the attached figure to better understand the problem

Let

x------> the major arc GEC

y-----> the minor arc GFC

$x+y=360\°$

we have

$x=230\°$

substitute in the equation and solve for y

$230\°+y=360\°$

$y=360\°-230\°=130\°$
