Answer:

let dimention of original garden be x

then (x-8)(x-5) = 180

x^2 -13x -140 = 0

(x-20)(x+7)=0

x= 20 or x = -7

x = 20

original area = (20)^2

= 400 m^2

Hi there,

There are 16 members in a math club such as 2 girls and 14 boys in a math club.

Divide both terms by 2.

14 ÷ 2 = 7

Therefore:

In a trolley ride around an amusement park, a child traveled from one signpost to a second signpost at a constant speed of 125 m
Inessa05 [86]

Answer:

Given speed of trolley = 125 meters per minute

Speed= 125 meters/minute\\\\Speed =\frac{125}{60}meters/second\\\\Speed=2.083m/s

Now we know that

Distance= Speed x time

Thus for the first case since the time of travel is less than 450 seconds thus the distance traveled is less than

Distance < 2.083 x 450 =937.5 meters

hence depending on the given information we cannot come to any conclusion weather the distance travelled is less than 800 m or greater than 800 m.

For the second case

since the time of travel is greater than 400 seconds

Thus the distance traveled is

Distance>2.083\times 400=833.2meters

which is greater than 800 meters.

A table costs $350. There is also a sales tax of 7%. How much does the table cost, including sales tax?
IrinaVladis [17]
Tax
$350x0.07
=$24.50

(0.07 is the 7% tax in decimal form)

Total cost
$350+$24.50
=$374.50

OR

$350x107%
=$374.50

1.07 is the table cost (100%) plus the sales tax (7%)

The table costs $374.50 with tax.
