Answer:
rate=55 percent
Step-by-step explanation:
SI=PRT
p=90
r=?
t=2
si=99
R=SI÷PT
R=99÷90×2
r=99÷180=0.55
r=0.55×100
R=55%
In the given question, there are several information's of immense importance. using these information's the correct and the required answer can be determined. It is given that an unknown number has to be found from the information's provided.
Let us assume the unknown number = x
Then
3x + 3 = 2x -1
3x - 2x = -1 -3
x = -4
So the unknown number is -4.
It should be remembered that these are trick questions and it is important to go through each lines very carefully to understand the inner meaning.
Answer:
stars.
Step-by-step explanation:
We have been given that a particular galaxy has a total mass of 
grams and the average star in that galaxy has a mass of 
grams. We are asked to find the number of stats in the galaxy.
To find the number of stats in the given galaxy, we will divide total mass of galaxy by mass of an average star in the galaxy as:
Using exponent property 
, we will get:
Therefore, there are approximately 1000,000,000,000,000,000,000,000 stars in the given galaxy.
Answer:
1. Convert the equation into point-slope form. (y=mx+b)
-2x+y=8 <em>becomes</em> y=2x+8
2. We can identify 8 as our y-intercept so plot 8 on the y-axis.
3. Start plotting points at 8. The slope 2x (2/1) should be plotted 2 units up and 1 unit right. Keep plotting points like this and you will achieve a linear slope.
