A rocket ship is travelling at an average speed of 1.75 × 104 miles per hour. How many miles will the rocket ship travel in 1.2 × 102 hours? 1. Write the expression: (1.75 × 104)(1.2 × 102) 2. Rearrange the expression: (1.75 × 1.2)(104 × 102) 3. Multiply the coefficients: (2.1)(104 × 102) 4. Apply the product of powers: 2.1 × 10y The rocket ship will travel 2.1 × 10y miles. What is the value of y in the solution? y =

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

1. minimum

2. 6400

3. eight

hope this !

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
