Answer:
(a) 
(b) Here the intercept means that we pay
more than
for each text message received
(c) 145 text messages sent and 30 messages received
75 text messages sent and 50 messages received
180 text messages sent and 20 messages received
Step-by-step explanation:
Here we have
X×0.02 + Y×0.07 = 5
Therefore the equation is

b. Here the intercept means that we pay
more than
for each text message received
c. Other combinations are
145 text messages sent and 30 messages received
75 text messages sent and 50 messages received
180 text messages sent and 20 messages received.
13.2 first look at the 2 if is lower then the number five so u round down to 0 the decimal stays there so it's no 13.0 now u do the same to the 13 only u round up since its higher so u round it up to 20 and ur answer should be 20.0

Answer: False</h3>
Here's a counter example to prove the statement to be incorrect
first number = 1
second number = -2
sum = 1 + (-2) = -1
difference = 1 - (-2) = 1 + 2 = 3
We see that the difference (3) is not smaller than the sum (-1)
Answer:
The area of a horizontal cross section at a height is 
Step-by-step explanation:
Given that,
Height = 14 m
Radius = 2 m
Let V be the volume of a right circular cone
We need to calculate the value of R
Using given data

Put the value into the formula



We need to calculate the area of a horizontal cross section at a height y
Using formula of area

Put the value into the formula

Hence, The area of a horizontal cross section at a height is 
We have,
1 hour = 60 minutes
Given,
27 miles per hour
= \frac{27~miles}{1 ~hour}
= \frac{27~miles}{60~minutes} because 1 hour = 60 minutes
= \frac{0.45~miles}{1 ~minute}
So, the human ran at a speed of 0.45 miles per minute
