What is the percent for;
lesantik [10]

Answer:

  1. 47%
  2. 98%
  3. 25%

Step-by-step explanation:

First you have to make it into a fraction, then multiply it by 100 :

Q1.

0.47 =  \frac{47}{100}

\frac{47}{100}  \times 100 = 47

Q2.

0.98 =  \frac{98}{100}

\frac{98}{100}  \times 100 = 98

Q3.

0.25 =  \frac{25}{100}

\frac{25}{100}  \times 100 = 25

What is the sum of an infinite geometric series if a1 = 144 and r = 1⁄4?
Brilliant_brown [7]

Answer:

D

Step-by-step explanation:

The sum to infinity of a geometric sequence is

sum to infinity = \frac{a_{1} }{1-r}

here a_{1} = 144 and r = \frac{1}{4}, hence

sum = \frac{144}{1-\frac{1}{4} }

      = \frac{144}{\frac{3}{4} }

      = \frac{144(4)}{3} = 192 → D

Solve the system of equations by graphing: -1/3x + y=-1, y=4+1/3x
Arada [10]

-\frac{1}{3}x + y = -1   ⇒   y = \frac{1}{3}x - 1

To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope (\frac{1}{3}) by counting up 1 and to the right 3 of the y-intercept.  This gives you a second point of (3. 0).  Draw a line through those two coordinates.

Answer: Plot (0, -1) and (3, 0) and draw a line through them.

***************************************************************************************

y = 4 +  \frac{1}{3}x    ⇒   y =  \frac{1}{3}x  + 4

Same as above.  Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).

Answer: Plot (0, 4) and (3, 5) and draw a line through them.

***********************************************************************************

You should end up with two PARALLEL lines.  Since the lines never intersect, there are no solutions to this system of equations.

Answer: No Solution
