Answer:
The amount invested at 7% is $1,400 and the amount invested at 9% is $7,600
Step-by-step explanation:
Let
x ----> amount invested at 7%
(9,000-x) -----> amount invested at 9%
we know that
The interest earned by the amount invested at 7% plus the interest earned by the amount invested at 9% must be equal to $782
so
The linear equation that represent this problem is
solve for x
therefore
The amount invested at 7% is $1,400 and the amount invested at 9% is $7,600
It is 8/-6 bcuz you go up 8 and then left 6 but it will be negative 6 bcuz its left
You divide by 16 so you can get each ingredient per serving then you multiply that by 4 and you get your answer
9.42 Units
Step-by-step explanation:
Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:
270/360; 360 being the total angle measurement of a circle
270/360 simplifies to 3/4
The fraction represents how much of the circle that arc covers
Now we have to find the circumference which would be
2(3.14)r
r = 2 therefore: 2(3.14)2 = 12.56
Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length
Which gives us 9.42
