Answer:

3.1 cm

Step-by-step explanation:

The difference in lengths is ...

13 5/10 - 10 4/10 = 3 1/10 . . . centimeters

Jenny's pencil is 3.1 cm longer than Jill's.

Comment on the subtraction

Above, we have converted both numbers to mixed numbers with a common denominator. You can just as easily convert both numbers to decimal values.

10 2/5 = 10 4/10 = 10.4

Then 13.5 -10.4 = 3.1, as above.

The wording "how much longer is A than B?" means, "what is the difference A - B?" That difference is found by subtraction. Many graphing calculators will let you enter mixed numbers as part of an expression, so your calculator may be able to find this value for you.

ella [17]

Answer:

The approximate population of the town in 2023 will be 291

Step-by-step explanation:

In 2015, the population of a small town in Florida is 95

So, The population of a small town in Florida = 95

Now, The increase in the population of a small town in Florida is 15%

We need to find the approximate population of the small town in 2013

Number of years from 2015 to 2023 = 8 years

So, we need to find the population increase in 8 years with the rate of 15%

Thus, The increased population = initial population × ( 1 + 15%)^8

⇒ The increased population = 95 × 1.15^8

= 290.61 ≈ 291

Therefore, The approximate population of the town in 2023 will be 291

The correct question is

A figure is formed by a square and a triangle. total area is 32.5 m^2. the area of the triangle is 7.5 m^2. what is the length of each side of the square?

we know that

The total area of the figure is equal to the area of triangle plus the area of square

The area of square is equal to the area f the figure minus the area of triangle

Let

A ----area of the square

$A=32.5-7.5=25\ m^2$
