Answer:

The perimeter of room is (20.6 \pm 0.4)~m

Step-by-step explanation:

We are given the following in the question:

The length and width of a room are measured with uncertainties.

There is  uncertainty of 0.1 m in each measurement.

Length = (5.5 \pm 0.1)~m

Width = (4.8 \pm 0.1)~m

Formula:

The perimeter of room is given by:

P = 2\times (\text{Length + Width})\\P = 2\times ((5.5\pm 0.1)+ (4.8\pm 0.1))\\= 2\times (10.3\pm 0.2)\\P = (20.6 \pm 0.4)~m

The uncertainties are also added and multiplied.

Thus,the perimeter of room is (20.6 \pm 0.4)~m

Miriams house has a markey value of 125,000. The tax accessory evaluated her property tax rate to be 42%. What is the assessed v
MakcuM [25]
If you use the formula it states Assessed Value = Market Value x Rate.
Assessed value = 125000
Rate = 42In addition to the rate, you must divide 42 by 100, which makes .42 then add 1.
42/100 = 0.42 + 1 = 1.42
125000(1.42) = 177500
$177,500 is Miriam's assessed value of her house.

Answer:

y=5-5/4x

Step-by-step explanation:

slope-intercept form:   y=mx+b (m= slope, b= y-intercept)

5x + 4y = 20

4y=20-5x

simplify

y=5-5/4x

emmasim [6.3K]

The continent which has 59% of the total population will have more than 5.31 billion people by 2050.

<u>Step-by-step explanation:</u>

It is given that,

  • The total number of people is 9 billion.
  • The estimated number of people in 2050 year is 5.31 billion.

Therefore, you need to find out which continent has the estimated number by finding the percentage value.

<u>To find what percent 5.31 is of billion is of 9 billion :</u>

Let x be the percentage to be calculated.

⇒ x percent of 9 billion is 5.31 billion.

⇒ (x/100) × 9 = 5.31

⇒ x = (5.31 × 100) / 9

⇒ x = 531 / 9

⇒ x = 59 %

∴ The continent which has 59% of the total population will have more than 5.31 billion people by 2050.
