Answer:

15 km

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2 + b^2 = c^2

Draw a triangle with 12 for x direction and 9 for y direction

The distance is the connecting line which is the hypotenuse

12^2 + 9^2 = c^2

144+81 = c^2

225 = c^2

Taking the square root of each side

sqrt(225) = sqrt(c^2)

15 =c

the diameter of a bike wheel is 25 inches. If the wheelmakes 20 Complete rotations, how far does the bike travel?

Iteru [2.4K]

Answer:

1571 in

Step-by-step explanation:

Given data

Diamter= 25 in

radius= 25/2= 12.5in

Circumference= 2πr

substitute

C=2*3.142*12.5

C=78.55in

In 1 revolution the bike will travel 78.55in

in 20 revolutions the bike will travel

=78.55*20

=1571 in

Answer:

Part 3) Miguel scored 29 points and Alonzo scored 25 points

Part 4) Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years

Step-by-step explanation:

Part 3) Let

x ----> the number of points that Miguel scored

y ---> the number of points that Alonzo scored

we know that

$x+y=54$ ----> equation A

$x=y+4$ ----> equation B

substitute equation B in equation A and solve for y

$(y+4)+y=54\\2y=54-4\\2y=50\\y=25$

Find the value of x

$x=25+4=29$

the solution is the point (29,25)

That means ----> Miguel scored 29 points and Alonzo scored 25 points

Part 4) Let

x ----> Morgan's age

y ---> Mr Santos' age

we know that

$x+y=44$ -----> equation A

$x=y-15$ ----> equation B

substitute equation B in equation A and solve for y

$(y-15)+y=44\\2y=44+15\\2y=59\\y=29.5$

Find the value of x

$x=29.5-15=14.5$

the solution is the point (14.5,29.5)

That means ----> Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years
