Answer:

more than 200 calls

Suppose number of calls = x

According to plan 1: Total monthly charge is $24

According to plan 2: Fix charge is $16 and $0.04 per call

cost of x's call = $0.04x

and monthly charge according to plan 2 = 0.04x + 16

a)  Plan 1 is more economical than plan 2.

0.04x + 16 > 24

solve it for x

.04x > 8

x > 200

b)   So,  if more than 200 calls are made then Plan 1 is more economical.

The daily mean temperature in a particular place is 83. how many cooling-degree days were accumulated?
olga55 [171]
Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. 65°F because we assume that at this temperature we do not need cooling or heating. 
In our case the daily mean temperature is 83°F and X is the number of cooling-degree days.
X=83-65
X=18

GalinKa [24]
Answer:
x = 4

Explanation:
For the right hand side:
log base 9 of 8 + log base 9 of (x-2) = log base 9 (8*(x-2))
                                                          = log base 9 of (8x-16)
For the left hand side:
2*log base 9 of x = log base 9 of x^2

Now, equating the two sides and solving for x:
log base 9 of (8x-16) = log base 9 of x^2
This means that:
x^2 = 8x - 16
x^2 - 8x + 16 = 0
(x-4)^2 = 0
Therefore:
x = 4

Hope this helps :)

The smallest of 6 consecutive integers is p, and the greatest is q. What is the value of the average of p and q in terms of p?
Paladinen [302]

Answer:

Option A.

Step-by-step explanation:

It is given that the smallest of 6 consecutive integers is p. So, all numbers are

p,p+1,p+2,p+3,p+4,p+5

The greatest is q.  

q=p+5

Now, the value of the average of p and q in terms of p is

Average=\dfrac{p+q}{2}

Average=\dfrac{p+p+5}{2}

Average=\dfrac{2p+5}{2}

Average=\dfrac{2p}{2}+\dfrac{5}{2}

Average=p+2.5

Therefore, the correct option is A.

1 point<br> 5) Solve by using the quadratic formula 8x² = 15 - 14x
kykrilka [37]
<h3>I'll teach you how to solve 8x² = 15 - 14x</h3>

----------------------------------------------------

8x² = 15 - 14x

Add 14x to both sides:

8x^2 +14x =15-14x+14x

Simplify:

8x^2 +14x =15

Subtract 15 from both sides:

8x^2+14x-15 = 15-15

SImplify:

8x^2+14x-15 = 0

Solve with the quadratic formula:

x= \frac{-14+ \sqrt{14^2-4*8(1-15)} }{2*8}  = 3/4

x= \frac{-14+ \sqrt{14^2-4*8(1-15)} }{2*8}  = -5/2

The solutions to the quadratic formula are:

x= 3/4, x=-5/2

Your Answer Is x= 3/4, x=-5/2

plz mark me as brainliest :)
