Mathematics
1 answer:
eimsori [14]3 years ago
5 0

Answer:

x=65/n where x is 1 book and n the number of books

Step-by-step explanation:

If n is the number of books, lets say 1 book is "x", then

nx=65

x=65/n

for example

n=1    then x=65

n=2 then x=65/2

n=3 then x=65/3

The reading on a car speedometer has 1.6% maximum error the speed limit on the road is 65 miles per hour
nasty-shy [4]

Answer:

For A) it is possible that the speed  the cat is going over the speed limit

For B) The statement is false as if the error is negative, the speed of the car will be less than the speed limit.

Step-by-step explanation:

Data provided in the question:

Maximum error  on a car speedometer = 1.6% = 0.016

Maximum Speed limit on the road = 65 miles per hour

Now,

The error will be ± 1.6%

Now,

When the speedometer reads 64 miles per hour

The possible speed of the car can be

64 miles per hour + Error

= 64 + [0.016 × 64]

= 64 + 1.024

= 65.024 miles per hour

or

The speed can be

64 miles per hour - Error

= 64 - [0.016 × 64]

= 64 - 1.024

= 62.976 miles per hour

Hence,

For A) it is possible that the speed  the cat is going over the speed limit

For B) The statement is false as if the error is negative, the speed of the car will be less than the speed limit.

What is the sum of interior angles for a nonagon
alexira [117]
Remember your prefixes! They help a lot, because there is a formula for this particular problem. Nonagon refers to a shape with 9 sides. 

The number of triangles a polygon has is represented by the formula: 
(n-2)

Where "n" is the number of sides. If you ever forget what you subtract "n" by think of a triangle. It has 3 sides, so it is only logical that you should only have 1 triangle (subtract by 2). So, what is the sum of the interior angles of a triangle, 180°. So the formula looks like this: 

Sum of Interior Angles = 180°(n-2)
180°(9-2)
180°(7) = 1260° is the sum of interior angles for a nonagon!

Mr. Sammie has now decided to expand his food truck business. Based on the information in the chart below, what Region will be b
Nady [450]

Answer:

SouthEast region

Step-by-step explanation:

#We need to find the truck density per region to be able to determine the most viable region for business:

Density=\frac{mass}{Area}\\\\d_{NW}=\frac{320}{10972}=0.0293\  truck/sq \ mi\\\\d_{NE}=\frac{400}{9485}=0.0422\ truck/ sq \ mi\\\\d_{C}=\frac{480}{11645}=0.0412\ truck/sq \ mi\\\\d_{SW}=\frac{515}{11589}=0.0444 \ truck/sq \ mi\\\\d_{SE}=\frac{250}{9933}=0.0252 \ truck/sq \ mi

SouthEast region has the lowest density of 0.0252 truck/sq mi hence the best region for expansion.

-A low food truck density is an indicator of a relatively low competition hence existance of a large market share yet to be dominated.
