= 200 meter per minute
Answer:
33, 97
Step-by-step explanation:
Start by setting up equations for the equivalent angles
3z + 2 + 79 = 180
3z = 99
z = 33
3z + 2 = y
3(33)+2 = y
97 = y
Answer:
1.61 * 10 ^8
3.3 * 10^-7
Step-by-step explanation:
Multiply the numbers and then add the exponents
2.3 * 10^1 * 7 * 10^6
2.3 *7 * 10^(1+6)
16.1 * 10^7
We need to make this scientific notation by moving the decimal one place to the left and adding 1 to the exponent
1.61 * 10 ^8
Multiply the numbers and then add the exponents
1.1* 10^-5 3*10^-2
1.1 *3 * 10^(-5+-2)
3.3 * 10^-7
