| a | = ?,  | b | = ?
We will solve the system of equations:
( 1 )  19 · cos 37° + b · cos 30° - a = 0
( 2 )  19 · sin 37° - b · sin 30° = 0
19 · 0.602 = b · 0.5
11.4345 = 0.5 b
 →
| b | = 22.8869 m
19 · 0.7986 + 22.8869 · 0.866 = a
 →
| a | =  34.995 m

Help me on my math please
Gnesinka [82]

Hi! I'm happy to help!

First you will need to split your line into the appropriate number of divisions. Because the fraction has a denominator (bottom) of 8, we split into 8 divisions. From there you count up from zero to 7, because it is 7/8.

0 is 0, the next dash is one, the next is two, and so on. The number one should be 8. Place the marker on the one that counts as 7.

I hope this was helpful, keep learning! :D

You deposit $2,000 in an account. The account earns $600 simple interest in 8 years.
attashe74 [19]

Answer:

4%

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=8\ years\\ P=\$2,000\\ I=\$600\\r=?

substitute in the formula above

600=2,000(8r)

solve for r

600=16,000(r)

r=600/16,000

r=0.0375

Convert to percent

r=0.0375*100=3.75\%

Round to the nearest whole percent
