11. What's the perimeter of a regular heptagon if one side measures 3 inches?

1 answer:

7 0

When a polygon is regular, that means that all of its sides are the same length and all of its angles are the same. A heptagon has seven sides and you know that all of them measure 3 inches. You can find the perimeter by adding all of the side measures together, so 3 + 3 + 3 + 3 + 3 + 3 + 3, or 3 x 7. So, the perimeter of the heptagon is 21 inches.

Step-by-step explanation:

let Sean be 4 years old and Rachel be 2 years old on April 17

part (A)

R=S-2 --(A)

is an equation that can be used to determine Rachel's age

likewise,

S=R+2--(B)

can be used to determine Sean's age

part (B)

use equation(A) for table (1) and equation(B) for table 2

Table (1) : R=S-2=11-2= R=9

12-2=10=»R=10

13-2=11=»R=11

14-2=12=»R=12

15-2=13=»R=13

16-2=15=»R=14

likewise use equation B for the table (2)

the outputs must be 3,4,5,6,7,8

and 9

The fare for an Uber is $5 per trip plus $0.50 per mile. The fare for the trip from the airport to the school center was $11.50.

Vinvika [58]

Answer:

13 miles

Step-by-step explanation:

The fare for the Uber

Cost= 5+ .5 m

where m is the number of miles

We spent 11.50

11.50 = 5 + .5 m

Subtract 5 from each side

11.5 -5 = 5+.5m -5

6.50 = .5 m

Divide by .5 on each side

6.5/.5 = .5m/.5

13 = m

We went 13 miles
