Answer:
The equation is 
whose solution is 
Step-by-step explanation:
Let us call 
the number of minutes the phone is used over 200 minutes, then we have
<em>(this says monthly bill of $40 plus the cost of phone usage over 200 minutes must equal $58 )</em>
This equation can be used to solve for u as follows:
Answer:
4.05 N
Step-by-step explanation:
A newton is kilograms times meters over seconds squared.
0.045 kg × 90 m/s² = 4.05 kg*m/s² = 4.05 N
Answer:
Sin X will still be 4/5
Step-by-step explanation:
When we dilate, we are making bigger the dimensions of a shape
While we can dilate the measure of the sides, same cannot be said about the interior or exterior angles of the shape
this is because these angles maintain their original value
so while by dilating, we have the sides measuring 8 to 10
The ratio of the angle still will be the same
this is because 8/10 is still same 3/5
But, to the simplest term
If all 22 tables had 6 people, there would be 132 people seated. There are 13 more than that, so 13 tables have 7 people.
Answer:
To solve this, we will need to use log properties. We know that subtracting two log equations gives us:
If log base 10 equals 2, we know that 
equals 100. We can solve this by:
= 100
5x³=100x²
x³= 20x²
x³-20x²=0
x²(x-20)=0
Thus, the answer is x=20.
