Let's say the number is x
75%of x is 15
75%x=15
0.75x=15
x=15/0.75
x=20

or you can say 3/4x=15
x=15*4/3
x=20

A taxi fare has a fixed charge of $1.75 and an additional charge $0.45 per mile. A fare for m miles is $13.90. Which equation co
Anestetic [448]

Answer:

B) 1.75 + 0.45m = 13.90

Step-by-step explanation:

To calculate the Taxi fare, we need to sum the fixed charge and the additional charge. Fixed charge ever is $1.75. The additional charge changes with the miles traveled (one mile costs $0.45, two miles $0.90, and so on), so we need multiply the charge ($0.45) by the miles m traveled.  

1.75 + 0.45 m

The problem says that the fare was equals to $13.90 so the final equation is

1.75 + 0.45m = 13.90

These box plots show the basketball scores for two teams.<br> Compare the shapes of the box plots
Alenkasestr [34]

Answer:

B

Step-by-step explanation:

Write a five-number summary for each distribution:

<u>Bulldogs:</u>

Min: 55

Q1: 70

Med: 80

Q2: 90

Max: 105

This distribution is symmetric, because Q1-Min=Max-Q2=15 and Med-Q1=Q2-Med=10

Tigers:

Min: 55

Q1: 60

Med: 65

Q2: 85

Max: 110

This distribution is not symmetric, because Q1-Min=15, Max-Q2=25 (15≠25) and Med-Q1=5, Q2-Med=20 (5≠20). This distribution is right-skewed or positively-skewed (has a long right tail)

So, correct option is option B

2. through: (8,5), perpendicular to y=-1/2x +4
SCORPION-xisa [38]
Perpendicular slope: flip sign and reciprocal = 2
Y = 2x + b
Plug in point (8,5)
5 = 2(8) + b
5 = 16 + b
b = -11
Equation: y= 2x - 11
