what is the productof(-3/5)and (-15)

A newspaper and magazine cost 220 together the newspaper cost 140 less than the magazine, then the cost of magazine is 180 and the cost of newspaper is 40.

Two or more expressions with an Equal sign is called as Equation.

Given,

A newspaper and magazine cost 220

the newspaper cost is 140  less than the magazine

Let x be the cost of magazine

x-140 is the cost of newspaper

x+x-140=220

2x-140=220

Add 140 on both the sides

2x=220+140

2x=360

Divide both sides by 2

x=180

and x-140=180-140=40

Hence, the cost of magazine is 180 and the cost of newspaper is 40.

Answer:

Faye's probability of pulling out a white marble is 3/80.

Step-by-step explanation:

To find the probability, we must first add everything up.  10 + 13 + 16 + 10 + 11 = 60 marbles.  Now we divide 60 by the amount of white marbles there are.  60 ÷ 16 = 3.75% or 3/80.  Therefore, the probability of Faye pulling out a white marble is 3/80.

Answer:

Step-by-step explanation:

The drawing scale is ...

  1/4" : 1 ft = 1/4" : 12" = 1 : 48

1) The bedroom shape has two pairs of parallel sides and right-angle corners. It is a rectangle.

__

2) The area of the drawing is 20(1/4 in) × (22(1/4 in)) = 440(1/16 in²)

  = 27.5 square inches . . . . area of the bedroom on the drawing

__

3) The drawing side of the bed is 1/48 of the bed's actual dimensions, so is ...

  54/48 in × 80/48 in = 1 1/8 in × 1 2/3 in . . . . size of the bed on the drawing

__

4) The drawing looks like it may have been made on a 1/4" grid, but there are only 17 grid squares along the side labeled 20 (feet). So, we actually have no good reference for size. Using the dimension marked as 3 feet for reference we estimated the bed size, trying for 4 1/2 by 6 2/3 feet.

When we print the figure to a piece of paper, we have to scale it to 88.1% to make the 20-foot dimension come out 5 inches. Doing that shows our bed outline is about 82 inches long, not 80 inches long. YMMV

Step-by-step explanation:

The question can be written as:

8 * 1.032^n = 140 000, this can be rearranged to

140 000/8 = 17500 = 1.032^n

now we need to find n, we could do this manually with a calculator, but an easier method is to use [tex]\log_x(y)[/tex]

example of log

2^3 = 8

log2 (8) = 3

log1.032 (17500) = 310.17

Answer:

[tex]\£3840.2[/tex]

Step-by-step explanation:

Let P denotes principal amount, T denotes time period and R denotes rate of interest.

Amount = [tex]P(1+\frac{R}{100})^T[/tex]

Amir pits £3035 into a bank account. The account pays 4% compound interest each year.

Put [tex]P=\£3035,\,R=4\%,\,T=6[/tex]

Amount = [tex]3035(1+\frac{4}{100})^6=3035(\frac{104}{100})^6=\£3840.2[/tex]

Therefore, Amir will have [tex]\£3840.2[/tex] in the account after 6 years.
