Answer:

7π mm²

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{280}{360}$ ( r is the radius )

= π × 3² × $\frac{28}{36}$

= 9π × $\frac{7}{9}$ ( cancel the 9's )

= π × 7

= 7π mm²

Answer:

The unit rate is accurately $\frac{1}{4}$ (km/minute)

Step-by-step explanation:

(1,1/4) means that the vehicle traveled 1/4 km within 1 minute.

The unit rate for this problem is also known as the speed of the vehicle.

So to find the speed, you need to use distance over time.

---> Unit rate: $\frac{1}{4}\\$ / 1 = $\frac{1}{4}$ (km/minute)

(2,1/2) means that the vehicle traveled 1/2 km within 2 minutes.

Same process:

---> Unit rate: $\frac{1}{2}$ / 2 =

Because of this, the unit rate is accurately $\frac{1}{4}$ (km/minute)

Suppose Wesley is a marine biologist who is interested in the relationship between the age and the size of male Dungeness crabs.

Eva8 [605]

Answer:

20.24 cm

Step-by-step explanation:

Here, since the age of the crab is given in months and the regression line was computed using the age in months, we just have to replace the value of the age in the formula to estimate the size.

The formula obtained for the estimated size Y was

Y = 9.1411 + 0.4775X

where X is the age in months

Replacing X with 23.2417, we get

Y = 9.1411 + 0.4775*23.2417 = 20.24 cm

Twenty-two more than a number is 47

Karo-lina-s [1.5K]

Answer:

the number is 25

Step-by-step explanation:

If the number is n, then twenty-two more is n + 22

which equals 47, so n+ 22 = 47

n = 47 - 22 = 25
