Step-by-step explanation:

The formula for calculating a circle's circumference is πd, where π is an irrational number (3.14....) and d is the diameter of the circle.

In the circle with diameter 19.5cm, the circumference is around 3.14 * 19.5cm = 61.23cm. (A)

Answer:

61.2

Step-by-step explanation:

circumference= 2πR

r=d/2

r= 19.5/2

r=9.75

circumference= 2×3.14×9.75

circumference= 61.2

Sheng owns the company Sandy Shores, which packages bottles of sand in two
LenKa [72]

Answer:

The maximum amount of sand in ounces that the company allows for each bottle is 25.5 ounces.

Step-by-step explanation:

The amount of sand that the company Sandy stores allows in each small bottle is determined by the amount of sand required for the bottle size plus the error in the amount of sand for the bottle size.

Now since each small bottle contains 25 ounces of sand and the error in the amount of sand contained in the bottle is 0.5 ounces, the amount of sand contained in the bottle = required amount ± error.

For the minimum amount, we subtract the error and for the maximum amount, we add the error.

Since the maximum amount is required, we have,

Maximum amount = required amount + error

required amount = 25 ounces and error = 0.5 ounces. So,  Maximum amount = 25 ounces + 0.5 ounces = 25.5 ounces.

So, the maximum amount of sand in ounces that the company allows for each bottle is 25.5 ounces.

Nesterboy [21]

Answer:

A

Step-by-step explanation: Scale Factor is defined as a ratio between the actual figure to that of the other figure.

And as it is clearly given in the question that 2 cm of length corresponds to 100 meters so the ratio comes out to be 1:50.

So the scale factor of the actual farm to the photo is A that is 1 to 50.

The variables y and x have a proportional relationship, and y = 5 when x = 4. What is the value of x when y = 8? Enter your answ
Charra [1.4K]

Answer

Find out the what is the value of x when y = 8 .

To prove

As given

The variables y and x have a proportional relationship.

y \propto x

y = kx

Where k is the constant of proportionality.

As y = 5 when x = 4

Put in the above

5 = 4k

k = \frac{5}{4}

Now find out the value of x , when y = 8

8 = \frac{5\times x}{4}

x = \frac{8\times 4}{5}

x= 6.5

Therefore when y = 8 than x = 6.4

Give the Domain And Range of the function.
Verizon [17]

Answer:

The last one

Step-by-step explanation:

Domain is on the x - axis, so it starts and stops on 1 and 6 and all the other symbols mean that x could be 1, 6, or anything in between. Range is on the y - axis, so the highest point is seven and the lowest is one. Y could be 1, 7, or anything in between.
