The path between the two houses and the path the homing pigeon will fly form a triangle. (Shown in picture)

To solve this problem you are finding the hypotenuse of the triangle. This can be solved using the Pythagorean theorem: a^2 + b^2 = c^2

Start by identifying your variables:
a: 6 (miles north)
b: 8 (miles west)
c: miles of the homing pigeon’s path

After identifying your variables, substitute the values into your equation.
This results in:
6^2 + 8^2 = c^2

Next, square both of your a and b values by multiplying each value by temselves. 6 x 6 is 36 and 8 x 8 is 64
So...
This leaves you with:
36 + 64 = c^2

After that, add your values together to get one value on each side of the equal sign.
36 + 64 = 100
This leaves you with 100 = c^2

To find your final answer, square root both sides to isolate and solve for the c value.
The square root of 100 is 10.

So your final answer is 10 miles.
The homing pigeon will fly 10 miles between Joe and Raul’s houses.

amm1812

Answer:

She has 9 5 cent stamps and 6 7 cent stamps.

Step-by-step explanation:

Let the number of five cent stamps be represented by F and the number of seven cent stamps be represented by S.

The difference between the number of five cent and seven cent stamps is 3

F-S=3

The sum of the collection from each type of stamp is 87 cents

5F+7S=87

Let us solve the equations simultaneously.

F-S=3

5F+7S=87

Using substitution method,

F= 3+S

5(3+S)+7S=87

15+5S+7S=87

12S=87-15

12S=72

S=6

F=3+S

=3+6=9

Therefore the number of five cent stamps is 9 and seven cent stamps is 6.

Find the surface area of each prism. Round to the nearest tenth if necessary while doing your calculations as well as in your fi
kakasveta [241]

Answer:

340 units2

Step-by-step explanation:

draw perpendicular line from upper left corner of trapezoid to cut bottom line(=9) into two part having length 3 and 6. Now a triangle and rectangle are formed.

The triangle has base=3, angle 60 degrees and angle of 90 degrees.

Finding third angle:

180-60-90= 30

finding other two sides of triangle by using law of sines:

a/sinA=b/sinB

3/sin30=b/sin60

b=3sin60/sin30

b=3(0.866)/0.5

b=5.2

b is the perpendicular line we drew

a/sinA=b/sinB

3/sin30=c/sin90

c=3sin90/sin30

c=3(1)/0.5

c=6

c is the hypotenuse of the triangle

Now Finding the perimeter of base:

The perimeter of the base=sum of the lengths of sides.

p=6+9+6+5.2

 =26.2

area of trapezoid:

A= (a+b)h/2

  = (6+9)(5.2)/2

  =39

total surface area of prism:

TSA= ph + 2A

where h is height of prism = 10

TSA= 26.2(10) + 2(39)

       =340

Hence total surface area of the given prism is 340 units square!

NemiM [27]

Answer:

$7.81

Step-by-step explanation:

89¢ + 95¢ + $1.79 + $1.29 + $2.89

So numerically to add it the equation is...

0.89 + 0.95 + 1.79 + 2.89 + 1.29 = $7.81
