The value of c is 233.3

Step-by-step explanation:

Given equation is:

$\frac{18}{20}c-250=-40$

To find the value of c, we have to isolate c on one side of the equation

So,

Adding 250 on both sides

$\frac{18}{20}c-250+250=-40+250\\\frac{18}{20}c=210$

Multiplying by 20 on both sides

$20*\frac{18}{20}c=210*20\\18c=4200$

Dividing both sides by 18

$\frac{18c}{18}=\frac{4200}{18}\\c=233.3333$

Rounding off to the nearest one decimal place

c=233.3

The value of c is 233.3

Tools are us rents leaf blowers for a base price of $24 +9 dollars per hour XYZ rentals rent leaf blowers for a base price of $1

Sidana [21]

Price per hour of first case :

$P_1 = 24 + 9a$ ( Here, a is number of hours )

Price per hour of second case :

$P_2 = 18 + 11b$ ( Here, b is number of hours )

Let, after x hours both company charges the same.

$P_1=P_2\\\\24+9x = 18 + 11x\\\\2x=6\\\\x = 3\ hours$

Hence, this is the required solution.

Find the ninth term of the

pantera1 [17]

Answer:

$a_{9}$ =0.00015241579

Step-by-step explanation:

Use the formula for geometric sequences:

$a_{n}$ = $a_{1}$ $r^{n-1}$

Substitute 1 in for $a_{1}$ , -1/3 in for r, and 9 in for n

$a_{9}$ =(1)(-1/3^9-1)

$a_{9}$ =(1)(-1/3^8)

$a_{9}$ =(1)(0.00015241579)

$a_{9}$ =0.00015241579

Hope this helps! :)

Suppose you have a valid argument with a false conclusion. Given this information, what do you know about the truth value of the

Katyanochek1 [597]

"The argument may be either valid or invalid" When trying to determine the validity of an argument in logic, the truth of a premise is a non-factor. Logic is concerned about whether or not an argument would effectively transfer truth from its premises to the conclusion if the premises were true.
