Step-by-step explanation:
18.75 x 11.54
= 216.375
216.375 is the correct answer
Step-by-step explanation:
<u>1. Divide 8 1/3 by 2 to find the value of x:</u>
<u>Turn</u><u> </u><u>8</u><u> </u><u>1</u><u>/</u><u>3</u><u> </u><u>into</u><u> </u><u>an</u><u> </u><u>improper</u><u> </u><u>fraction</u><u>:</u>
<u>Find the reciprocal (opposite) of 2/1, then multiply:</u>
x = 25/6 or 4 1/6
<u>2. 8.1 can be put over 1</u><u>:</u>
<u>Turn</u><u> </u><u>2</u><u> </u><u>1</u><u>/</u><u>3</u><u> </u><u>into</u><u> </u><u>an</u><u> </u><u>improper</u><u> </u><u>fraction</u><u>:</u>
<u>Find</u><u> </u><u>the</u><u> </u><u>reciprocal</u><u> </u><u>(</u><u>opposite</u><u>)</u><u> </u><u>of</u><u> </u><u>8</u><u>.</u><u>1</u><u>/</u><u>1</u><u>,</u><u> </u><u>then</u><u> </u><u>multiply</u><u>:</u>
7/24.3 is your simplified answer.
Answer:
b which is 20 each time they add 5
100 = x^2 + y^2
So
2 x dx/dt + 2y dy/dt =0
So
dy/dt = -x/y dx/dt
= -x/sqrt(100-x^2) * 7 At x=3
