Given
SaveMore
Required
Determine the equation
Let
So, we have:
The equation for the second company is not given. So, the (b) part cannot be correctly answered.
A general solution to the (b) part is:
Assume the equation is:
Next, we equate both
i.e.
This gives:
Collect like terms
Divide by 0.2
<em>Hence, the charges will be the same after 30 texts</em>
8 2/5 = 8.4 is your answer.
Answer:
x =
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = , then
sin30° = = = ( cross- multiply )
2x = 13 ( divide both sides by 2 )
x =
Answer:
172 cm^2
Step-by-step explanation:
Since it is a rectangular prism, you would have 6 sides, with two of them being the same. Each side is the values but multiplied by each other. So 7x2, 8x2, and 7x8. If you add them up it would be 14+16+56= 86, but that is only 3 sides, so you need to multiply 86 by 2, thus 172.
