The figure below is a regular octagon with a side - 1

Answers

Answer 1
Answer:

Answer:

309in²

Step-by-step explanation:

Area of an octagon is expressed as;

A=2(1+√2)a²

a is the side length of the octagon

Given

a = 8

Substitute into the formula

A = 2(1+√2)(8)²

A = 2(1+√2)(64)

Expand

A = 2(64+64√2)

A = 128+128√2

A = 128+128(1.414)

A = 128+181.01

A = 309in²

Hence the area of the octagon is 309in²

Answer:

Hello There!

~~~~~~~~~~~~~~~~~~

Kendra is planning to ride her bike that is 84 miles long. She plans to average 7 miles per hour. How long will the trip take?

-----

time = distance/rate

-----

t = 84 miles/7 m/hr = (84/7)hrs = 12 hrs.

Cheers,

The following data are arranged in ascending order and the median of the data is 60.Find the value of x.
26, 29, 42, 53, x, x + 2, 70, 75, 82, 93

Answers

The median of the data is 60. That means the two middle numbers divided by 2 = 60.

(x + x + 2) / 2 = 60...multiply by 2
2x + 2 = 120
2x = 120 - 2
2x = 118
x = 118/2
x = 59

x + 2 = 59 + 2 = 61

so ur numbers go : 26,29,42,53,59,61. 70, 75, 82, 93

Antonio and Candice had a race. Their distances past a particular landmark as the race progressed can be represented by linear functions and are shown in the table of values and graph below. Which statement is true regarding Antonio and Candice’s race?Antonio’s Distance Past the Landmark
Time (seconds)
8
12
16
20
24
Distance (meters)
29
41
53
65
77

A graph titled Candice's Distance Past the Landmark has time (seconds) on the x-axis, and Distance (meters) on the y-axis. A line goes through points (5, 22), (10, 42), (15, 62) and (20, 82).

Answers

Antonio had a head start of 3 meters.

We have

Antonio’s Distance Past the Landmark

Time (seconds)      8       12     16      20     24

Distance (meters)   29      41      53    65      77

Change in distance = 12 m

Change in time = 4 seconds

Slope = 12/4 = 3 m/ sec

So, equation of line y = 3x +5

Also a graph titled Candice's Distance Past the Landmark has time (seconds) on the x-axis, and Distance (meters) on the y-axis.

And a line goes through points:

(5, 22), (10, 42), (15, 62) and (20, 82).

Change in distance = 42-20 = 20 m

Change in time = 10-5 = 5 seconds

Slope = 20/5 = 4 m/ sec

So, equation of line y = 4x + 2

Taking the difference

5-2=3

Therefore, Antonio had a head start of 3 meters.

Round to the nearest whole number: 25.41
A. 26
B. 25.4
C. 25.5
D. 25

Answers

B and C cant be it because its not a whole number and it is .4 so it cant go up one making D the only possible choice.
D, 25, because if its less than 5, you keep the number the same, however, if its 5 and up, you round up.In this number the tens place contains a 4, so you have to round the same. In conclusion, 25.41 is rounded to 25, so your answer is D.

Can someone may help me with solving system of solving equations plzA small soda costs $0.45 and a large soda costs $0.65. 35 sodas were sold for a total of $18.55. How many of each size soda were sold?

Answers

let number of small sodas sold be x
# of large sodas sold be y
so
x + y =35
x=35 - y {equation1}
now next equation
0.65x + 0.45y = 18.55 { divide all by 0.50}
1.3x + 0.9y = 37.1 { put x = 35 - y (from eq 1)}
1.3 (35 - y) +0.9y = 37.1
45.5 - 1.3y + 0.9y = 37.1 {subtract 45.5  from both sides}
-0.4y = -8.4 { divide both by -0.4}
y = 21
so #of large sodas sold is 21
# of small sodas sold is 35 -21 = 14
