Answer: 8 + 4x = 30
Step-by-step explanation:
Since the admission fee to a state fair is $8.00 and each ride costs an additional $4.00. This can be represented in an equation as:
= 8 + 4x
where x = number of rides
Since Karen only has $30.00, the inequality that could be used to determine the number of rides, x, Karen can go on will be:
8 + 4x = 30
We can further solve the equation which will be:
8 + 4x = 30
4x = 30 - 8
4x = 22
x = 22/4
x = 5.5
She can go on 5 rides

Answer:
$3720
Step-by-step explanation:
If he makes $40 an hour for 60 hours, he makes $2400 there on the spot.
He worked 11 hours overtime, but it is double time, so 22 hours, and also, one and a half overtime pay, So, 22 hours × 40 × 1.5 = 22×60=1320. So, he made $1320 for working overtime.
In total, he made a total of 1320+2400=3720.
He made $3720.

Answer:
151
Step-by-step explanation:
So you have to start by finding the total number of degrees inside the shape. The shape has 5 sides.
So using this formula:
(n-2) * 180
(5-2) * 180
= 540 degrees inside the shape
Then solve for x.
5x +2 + 10x - 3 + 8x -19 + 13x - 31 + 7x -11 = 540
43x -62 = 540
43x = 602
x = 14
Plug in for S.

The scores on an exam were normally distributed with a mean of 84 and a standard deviation of 5. What is the probability that a randomly selected class member scored above 79? Answer as a percentage.
Answer:
0.841 (equivalent to 84.1%
Step-by-step explanation:
Chances are that your calculator has several different probability distribution functions built in. Here we need the function normal(
Typing that into a calculator, as follows, returns a decimal fraction which also represents the percentage of the time that a randomly selected class member scored above 79:
normalcdf(79, 1000, 84, 5) = 0.841 (equivalent to 84.1%)

Find the area of the figure.
Hurry please.
A 12 foot by 8 foot rug covers the hardwood floor of a room. The rug leaves a uniform
strip of bare floor surrounding the rug. If the area of the room is twice the area of the
rug, what is the equation you will use to solve for x?
Answer: 2(12 × 8)
Step-by-step explanation:
The area of the rug will be gotten by multiplying the length by its width. This will be:
= 12 foot × 8 foot
= 96feet²
Since the area of the room is twice the area of the rug, the equation you will use to solve for x will be:
= 2(12 × 8)
= 2(96)
= 192feet²

Answer:
15/17
Step-by-step explanation:
Cosine is equal to adjacent/hypotenuse. Since we don't have the hypotenuse in this case, we need to solve for it.
15^2+8^2=c^2
c=17
We get 17 for the hypotonuse.
Plug it into the equation adjacent/hypotenuse and you get 15/17

Consider the following geometric sequence
-5, 20, -30, 40, ...
If the explicit formula for the sequence above is expressed in the form aₙ = b*c^n-1, determine the values of b and c.
Answer:
b = -5 and c = -4
Step-by-step explanation:
The common ratio here is r = 20/(-5), or -4, and the first term, a(1), is -5. Thus, the explicit formula is
a(n) = a(1)*r^(n -1) (must use parentheses, as shown)
and so we have a(n) = -5*(-4)^(n - 1). b = -5 and c = -4
please... help me..I have a confusion..
is the (-5 + -3 ) is =( -5 - +3)
Answer:
They are the same
Step-by-step explanation:
We are to check if (-5 + -3 ) =( -5 - +3)
First you must know that the product of a positive and a negative n=sign will result in a negative sign i.e. + * - = -
Applying this in question;
(-5 + -3 )
= -5 - 3
= -8
similarly
( -5 - +3)
= -5 - 3
= -8
Since both values are the same hence, (-5 + -3 ) =( -5 - +3)
