Answer:
A
Step-by-step explanation:
Collecting terms of the expression, we have ...
x + 0.1x = x(1 +0.1) = 1.1x
In words, adding 10% is the same as multiplying the value by 1.1. Choice A is appropriate.
Answer:
r = - 
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = 
← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = 
( multiply both sides by - 6 )
12 = k, thus
r = 
← equation of variation
when t = - 7, then
r = 
= -
Hey there!
5 x w = 10 to the second power . . .
10 x 10 = 100
5 x 100 = 500
5 x w = 500
500 = 5w
w = 100 <-------
Hope this helps you.
Have a great day!
Tan^-1 = 72.81° is your answer, use basic SOHCAHTOA functions
If you would like to know the equation that shows the number of teaspoons of sugar needed to make x candy bars, you can calculate this using the following steps:
2.5 teaspoons of sugar ... 1 candy bar
y teaspoons of sugar = ? ... x candy bars = ?
2.5 * x = 1 * y
2.5 * x = y
y = 2.5 * x
The correct result would be <span>y = 2.5 * x.</span>
