Answer:
D 0.00009
Step-by-step explanation:
9 × 10^-5 = 9 × 1/10^5 = 9 × 1/100,000
= 9 × 0.00001
= 0.00009

<em>Comment on place value</em>
The exponent of 10 associated with the place value in a decimal number increases from 0 to the left of the decimal point, and decreases from -1 to the right of the decimal point:
100. = 10²
10. = 10¹
1. = 10⁰
0.1 = 10⁻¹
0.01 = 10⁻²
0.001 = 10⁻³
0.0001 = 10⁻⁴
0.00001 = 10⁻⁵
This simple realization can help you immensely with scientific notation.
What do you need to do with it
If you're solving for d your answer is d = -t,rt
If you're evaluating the problem your answer is t = d/r
If you're solving in terms of arbitrary letter d your answer is r=d/t
I hope this helps!
Answer:
so to solve an inequality you just treat the inequaltity sign like an equals sign except if you multiply by negative 1 you flip the direction of the sign.
p-7/12>3/10
add 7/12 to both sides
p>7/12+3/10
p>35/60+18/60
p>53/60
so if you had to graph this on a number line you would have an open circle on 53/60 and an arrow coming off pointing to the right

Answer:
Danny
Step-by-step explanation:
Its quite obvious really.
Multiply Danny's charges by 2
20 x 2
Thats $40 for 4 hours unlike Martins $68 for 4 hours.
If you wanna go further,
Minus Martins charges with Dannys
68 - 40
Thats a $28 gap.
