Answer:

Step-by-step explanation:

Let L represent the length of the rectangular porch.

Let W represent the width of the rectangular porch.

The area of the rectangular porch is expressed as LW.

Bills new porch is rectangular with an area of 50 square feet. Therefore,

LW = 50 - - - - - - - - 1

if the length is two times the width, it means that

L = 2W

Substituting L = 2W into equation 1, it becomes

2W × W = 50

2W^2 = 50

W^2 = 50/2 = 25

W = √25 = 5

LW = 50

5L = 50

L = 50/5 = 10

The perimeter of he rectangle is

Perimeter = 2(L + W)

Perimeter = 2(10 + 5) = 2 × 15

Perimeter = 30 feet

The sum of two numbers is 18. 5 times the first number subtracted from 4/7 of the second number is 14. Find the number.
Sergeu [11.5K]

Answer:

The sum of two numbers is 18.

5 times the first number subtracted from 4/7 of the second number is 14.

First number --> x

Second number --> y

so

x + y = 18 --> x = 18-y

5x - (4/7)y = 14

so

5 (18-y) - (4/7)y = 14

90 - 5y - 4/7 y = 14

-5.57 y = 14-90

y = 13.64

so

x = 18 - 13.64

x = 4.36

Semmy [17]

Answer: 0.62

Step-by-step explanation:

Given : A recent Harris Poll survey of 1010 U.S. adults selected at random showed that 627 consider the occupation of firefighter to have very great prestige.

i.e. The sample size of U.S. adults : n= 1010

The number of U.S. adults consider the occupation of firefighter to have very great prestige : x= 627

Now , the probability that a U.S adult selected at random thinks the occupation of firefighters has very great prestige will be :

\hat{p}=\dfrac{x}{n}\\\\=\dfrac{627}{1010}=0.620792079208\approx0.62  [ To the nearest hundredth]

Hence, the estimated probability that a U.S adult selected at random thinks the occupation of firefighters has very great prestige = 0.62

Put these numbers in order from least to greatest 12%, -1/2, 0, -0.22, 0.56
uysha [10]

Answer: -1/2, -0.22, 0, 12%, 0.56

Step-by-step explanation:

-1/2 is equal to -0.50, making it the number with the least value.

-0.22 is closer to 0 than -0.50, meaning it is greater then -0.50 and less than 0.

0 is between the negative and positive numbers, giving it the spot that it has.

12% is equivalent to 0.12, meaning it is more than 0, and less than 0.56, which is the greatest number.

0.56 has more value than any other number in the problem, meaning it goes last in the order.
