Answer:
Step-by-step explanation:175.42x .20=35.08 35.08Divided by 11=3.19
so each would pay 3.19 tip
total each would pay for bill would be 175.42+35.08=210.50
210.50divided by 11 =19.14
The slope of line A is m= 1/3
Using the compound interest formula,
572.86=287,50(1+i)^8
(1+i)^8=572.86/287.50=1.992557
1+i=(1.992557)^(1/8)=1.0899996
=>
i=1.0899996-1=9%
Note: This problem can also be solved in the head using the rule of 72.
Since after 8 years, the amount is roughly doubled, we can say that the interest rate is approximately 72/8=9%
Formula: 1/2(d1)(d2), 12+4=16/2.3+2.3=4.6, 16*4.6=73.6, 73.6/2=36.8. Area=36.8
-Hope this helps! :)
Answer:
To find a
sin 30=a/6in
1/2=a/6in
2a=6in
a=6in/2
a=3in
To find b
cos 30=b/6in
/3/2=b/6in
2b=/3*6in
b=2/3(two radical three)
I don't get the radical sign so I use / sign on the last 3 steps on the second
