Answer: x=17 (if that’s what you mean)

explanation: a straight line is 180 degrees, so we can minus 180-115 which will give you 65, and if you set the equation given equal to 65, you’ll get 17

12 out of 18 people taken

4 groups made

12+3=15

15 out of 18 people taken

5 groups made

15+3=18

Fine the area of the regular figure
Sloan [31]

Answer:

139.5 mm

Step-by-step explanation:

The area of a geometric shape with all sides of equal length is:

A (1/2)nsr

n = the number of sides

s = the length of the sides

r = the length of the apothem

The apothem is the line going from the center point of the shape to the middle of one of the sides.

A = (1/2)(5)(9)(6.2)

A = (1/2)279

A = 139.5 mm

Dina and Masha started out on a 10 km bike path at the same time. When Dina reached the end of the 10 km, Masha still had 2 km t
german

Answer:

4 km/h

Step-by-step explanation:

We are told that Dina and Masha started out on a 10 km bike path at the same time.

Dina's biking speed is 5 km/h.

Let us find taken by Dina to cover 10 kn distance.

\text{Time}=\frac{\text{Distance}}{\text{Speed}}

\text{Time taken by Dina to cover 10 km}=\frac{10km}{5\frac{km}{hr}}

\text{Time taken by Dina to cover 10 km}=\frac{10km}{5}\times \frac{hr}{km}}

\text{Time taken by Dina to cover 10 km}=2hr

Therefore, Dina took 2 hours to complete 10 km.

Since both started at the same time, therefore, Masha also took 2 hours to complete 2 km less than Dina.

Let us find distance covered by Masha.

\text{Distance covered by Masha}=10\text{ km}-2\text{ km}=8\text{ km}

Now let us find Masha's biking speed.

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

\text{Masha's biking speed}=\frac{8\text{ km}}{2\text{ hour}}

\text{Masha's biking speed}=4\frac{\text{ km}}{\text{ hour}}

Therefore, Masha's biking speed is 4 km per hour.
