Answer:

7/32

Step-by-step explanation:

1. Subtract the 3/4

1 - 3/4 = 1/4

2. Find what 1/8 of 1/4 is

1/4 × 1/8 = 1/32

3. Subtract it from 1/4

1/4 - 1/32

4. Multiply 1/4 by 4/4 to get a common denominator to subtract

1/4 × 4/4 = 8/32

8/32 - 1/32 = 7/32

Lily has two times as much money invested in 8% stocks as she has in bonds paying 6%. How much she has invested in stocks if her
EleoNora [17]

Answer:

Final answer is $4440.

Step-by-step explanation:

Let amount of money invested in 8% stock = x

Let amount of money invested in 6% stock = y

then total money invested $325.6 gives equation

8% of x + 6% of y = 325.6

0.08x + 0.06y = 325.6

8x + 6y = 32560...(i)

other equation will be x=2y...(ii)

plug (ii) into (i)

8x + 6y = 32560

8(2y) + 6y = 32560

16y+ 6y = 32560

22y = 32560

y=\frac{32560}{22}

y=1480

plug y=1480 into (ii)

x=2y=2(1480)=2960

Then total money invested in stocks = x+y= 1480+2960=4440

Hence final answer is $4440.

PLEASE HELP ME ! Convert the following description to a proper scale ratio:
galina1969 [7]

Answer:

  1 : 400,000

Step-by-step explanation:

A map scale is usually represented as a unit fraction, one with 1 in the numerator. It has no units, which is to say that it is the ratio of same units.

It can be found by dividing the map dimension by the ground dimension when both are expressed in the same units.

  (8.4 cm) / (33.6 km) = (8.4×10^-2 m) / (33.6×10^3 m) = (8.4/33.6)×10^-5

  = 0.25×10^-5 = 1/400,000

__

<em>Additional comment</em>

Map scales are often expressed using the colon for the ratio unit separator:

  1 : 400,000
