Answer:

\$ (\frac{j+15}{3} )

Step-by-step explanation:

There were three friends and the total fare was $j

Each of the friends pays \$ (\frac{j}{3} ) for their cab fare.

Since Angela also paid a $5 Tip

Total Amount Paid by Angela = Share of cab fare + Tip

\$ (\frac{j}{3} ) + \$5

We can simplify this further by taking the LCM.

\$ (\frac{j}{3} ) + \$5=\$ (\frac{j+15}{3} )

The total amount paid by Angela therefore is :\$ (\frac{j+15}{3} )

Describe the effect on the area of a circle when the radius is doubled
galina1969 [7]

Answer:

The original area would be multiplied by the scale factor of 2² to get the new area.

Step-by-step explanation:

If you double the radius lets so lets do an example

(a=πr²) so

if x is the radius the area would be x²π      

double the radius so 2x then the area would be

(2x)²π so 4x²π

4x²π/x²π= 4 so its 4 times greater or

D the last answer or The original area would be multiplied by the scale factor of 2² to get the new area.

The junior and senior classes at Central High School were asked to choose a destination for a field trip. The results are shown
Ann [662]

Solution:

We are given below frequency table:

             Amusement-Park      Museum         Broadway-Show         Total

Juniors                57                      21                      42                          120

Seniors                64                     44                      58                          166

Total                    121                     65                      100                        286

We have to find the percentage of surveyed students who chose the amusement park.

From the table, we see there are total 121 students who chose amusement park out of total 286 students.

Therefore, the percentage of surveyed students who chose the amusement park is given below:

\frac{121}{286}\times 100=42.3\%

Hence, the option A. 42.30% correct.

Probability of landing in the white not the red. Please helpppppppppppp!
Iteru [2.4K]

Fun, geometry disguised as probability.

That's a pentagon, which we can view as 10 right triangles with legs a and s/2 (half of s) and hypotenuse r.  So area of the pentagon is

P = 10 × (1/2) a (s/2) = 10 (1/2) (3.2) (4.7/2) = 37.6

The area of the circle is πr² so the circle area is

C = π (4²) = 50.265482

The white area is the difference, C-P, and the probability we seek is the fraction of the circle that's white, so (C-P)/C.

p = (C-P)/C =1-P/C = 1-37.6/50.265482 = 0.251971

Answer: 0.25

Higher than I would have guessed from the figure.
