Answer:
i don't know
Step-by-step explanation:
i don't know
1/2x + 3/4y = 4 ....multiply everything by 4
2x + 3y = 16
3y = -2x + 16
y = -2/3x + 16/3
In y = mx + b form, the slope will be in the m position and the y int will be in the b position
y = mx + b
y = -2/3x + 16/3
so ur slope is -2/3 and ur y int is (0,16/3)
Answer:
38.485(correct to 5 significant figure)/ 12.25π
Step-by-step explanation:


=38.485(cor. to 5 sig.fig.)/ 12.25π
to find arc length of sector,we need to π(radius²)(sector's degree divided by 360 degree)
53 times .07 is 3.71
53 times .15 is 7.95
You add those and get $64.66.
