a state employees pension fund invested a total of one million dollars into two accounts that earned 3.5 and 4.5 annual simple i

erik [133]

Let the investment in first account be x and this account is earning 3.5% interest

So Interest on this account is 3.5% of x = 0.035x

So the investment in second account would be (1,000,000-x) and this account is earning 4.5% interest

So the interest on this account is 4.5% of (1,000,000-x) = 0.045*(1,000,000-x)

Given that total interest for the year is $42,000

So we have

0.035x + 0.045(1,000,000-x) = 42,000

0.035x - 0.045x + 0.045*1,000,000 = 42,000

-0.01x + 45,000 = 42,000

-0.01x = 42,000-45,000

-0.01x = - 3000

0.01x = 3000

x = 3000/0.01

x= 3,00,000

Therefore Investment in one account s 300,000 and the investment in other account is 1,000,000-300,000 = 700,000

The Sanchez family drove 132 miles in 3 hours before lunch. Then they drove 240 miles in 5 hours after lunch.

lilavasa [31]

The formula for speed is the total distance traveled over time. We shall calculate the 2 speeds individually- before and after lunch. Afterwhich, we shall add them together and divide by 2 to get the average.
Before lunch s = 132 mi / 3 hr = 44 mi/hr
After lunch s = 240 mi / 5 hr = 48 mi/hr

Ave s= 48 + 44 / 2
Ave s= 46 mi/hr

Therefore the correct answer is A.

-20x+18≥-102 solve this inequality

larisa [96]

Answer:

1) x≥6

--------------------------------------

2) h > 20

Mark worked more than 20 hours.

Step-by-step explanation:

1) -20x+18≥-102

-20x≥-102-18

-20x≥-120

Dividing -20 both side

$\frac{-20}{-20}x$ ≥ $\frac{-120}{-20}$

x≥6

--------------------------------------

2) 14h + 25 > 305

14h > 305-25

14h > 280

Dividing 14 both side

$\frac{14}{14}h > \frac{280}{14}$

h > 20

Mark worked more than 20 hours.
