Answer:
$2611.05
Step-by-step explanation:
earnings = lane rentals + concessions
Friday:
earnings = $842.72 +412.38 = $1255.10
Saturday:
We assume "down by 1/8" means the value was 1 -1/8 = 7/8 that of the previous day. Likewise, "increased by 1/2" is assumed to mean the value was 1 + 1/2 = 3/2 that of the previous day.
earnings = 7/8×$842.72 + 3/2×412.38 = $1355.95
__
Then the total earnings for both days were ...
$1255.10 +$1355.95 = $2611.05
Answer:
$1,355.95
$1,580.10
$1,992.48

A plot of land is in the shape of a triangle. If one side is x meters, a second side is (5x - 2) meters and a third side is (7x-3) meters, express the perimeter of the lot as a simplified expression in x.
Hey there! I'm happy to help!
The perimeter is the distance around a shape. Let's add up the lengths of our sides to ind it.
x+5x-2+7x-3
We combine all of the x values.
x+5x+7x=13x
And all of the constants.
-2-3=-5
Therefore, the perimeter is 13x-5.
Have a wonderful day! :D

Round to the nearest cent.
5. $406.439
Answer:
406.4
Step-by-step explanation:
When rounding you only look at the number you're rounding and the one before it. In this case it would be the 4 and 3 after the decimal since we're rounding to the nearest cent. If the numbers before the one you're rounding are 0-4 then you leave the number the same. If the numbers are between 5-9 then you add one to the number. Since the number before 4 is between 0-4 you leave it as 4. But if it was between 5-9 then you'd change the 4 to 5.
Solve 3(x + 1) + 6 = 33.
add 6 plus 33 then do x+1 then you divide

Megan expects to save an average of 5 dollars per
week from her babysitting earnings. The relationship
between time and the amount of money she saves is
shown on the graph. Which other ordered pairs would
fall on this line? Select all that apply.
A. (0.5, 2.5)
B. (3, 18)
C. (0,0)
D. (4.5, 30)
Answer:
Step-by-step explanation:
Ordered pair (0, 0) & (0.5, 2.5) will fall on the line of graph
Step-by-step explanation:
Megan expects to save an average of 5 dollars per week from her babysitting earnings.
=> Saving Per week = 5 $
Saving in 0.5 Week = 0.5 * 5 = 2.5 $
hence ordered pair (0.5, 2.5) will fall on the line of graph
Saving in 3 Week = 3 * 5 = 15 $
Hence (3, 18) will not fall on line
Saving in 0 Week = 0.5 * 0 = 0 $
hence ordered pair (0, 0) will fall on the line of graph
Saving in 4.5 Week = 4.5 * 5 = 22.5 $
Hence (4.5, 30) will not fall on line
Ordered pair (0, 0) & (0.5, 2.5) will fall on the line of graph
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
here, we have,
Megan expects to save an average of 5 dollars per week from her babysitting earnings.
=> Saving Per week = 5 $
Saving in 0.5 Week = 0.5 * 5 = 2.5 $
hence ordered pair (0.5, 2.5) will fall on the line of graph
Saving in 3 Week = 3 * 5 = 15 $
Hence (3, 18) will not fall on line
Saving in 0 Week = 0.5 * 0 = 0 $
hence ordered pair (0, 0) will fall on the line of graph
Saving in 4.5 Week = 4.5 * 5 = 22.5 $
Hence (4.5, 30) will not fall on line
Hence, Ordered pair (0, 0) & (0.5, 2.5) will fall on the line of graph.

The Distribution of Sample Means expresses the way in which sample means taken from a population and of a given sample size are distributed around the population mean.
a. True
b. False
Answer:
a. True
Step-by-step explanation:
This is because, since the sample mean equals the population means, the distribution of the sample means about the sample size would also be the distribution of the sample size distributed about the population mean.
This usually results in a normally distributed population for a sample size greater than 30.
So, if the sample size is greater than 30, the population mean and sample mean would have the same value and distribution.

The length of a rectangle is 4 inches less than 4 times the width. If the perimeter is 72 inches, find the length and the width of the rectangle.
Answer:
Length is 28. Width is 8.
Step-by-step explanation:
The perimeter of a rectangle is given by the following formula:
[tex]P=2l+2w[/tex]
We know that the length is 4 inches less than 4 times the width. Therefore:
[tex]l=4w-4[/tex]
Substitute this for l. Let's also substitute 72 for P. Therefore:
[tex]72=2(4w-4)+2w[/tex]
Distribute:
[tex]72=8w-8+2w[/tex]
Combine like terms:
[tex]72=10w-8[/tex]
Add 8 to both sides:
[tex]80=10w[/tex]
Divide both sides by 10:
[tex]w=8[/tex]
Therefore, the width is 8.
The length is 4 less than 4 times the width. Thus: "
[tex]l=4(8)-4[/tex]
Multiply:
[tex]l=32-4[/tex]
Subtract:
[tex]l=28[/tex]
Therefore, the length is 28 and the width is 8.
And we're done!

7. Is plane TPS an acceptable name for plane R? Why or why not?
Answer:
Hi
Step-by-step explanation:
Hi
what is (- 4/5) x (- 5/8)
Answer:
- 1/2
Step-by-step explanation:
(-4/5) × (- 5/8)
- 4/5 × - 5/8
First we mulitply across
The top and the bottom.
- 20 / 40
because -4 × -5 = +20
and -5 × -8 = +40
Now we simplify the fraction
- 20 / 40
= - 2 /4
= - 1/2
Because we have to simplify it and so I divided it by 10 first.
-20 ÷ 10 = -2 and -40 ÷ 10 = -4
Then I simplified it again by dividing it by 2.
-2 ÷ 2 = -1 and -4 ÷ 2 = -2
So finally we have:
-1/2
And we cannot simplify that anymore so that is the answer.
Hope that helped!
Answer:
1/2
Step-by-step explanation:
since negative * negative= positive we multiply the top and bottom to get. 20/40 which simplifies
Which size would you see on the box for a new television whose screen measures 32 inches wide by 18 inches high?
Answer:
37
Step-by-step explanation:
The calculation of size for a new television is shown below:-
With the help of Pythagoras theorem
[tex]h^2 = b^2 + p^2[/tex]
where
h indicates hypotenuse which is the diagonal length
b indicates the base which is the length of the horizontal side
p indicates perpendicular which is the TV length of the vertical side.
[tex]h^2 = \sqrt{b^2 + p^2}[/tex]
now, we will put the values into the above formula
[tex]= \sqrt{32^2 + 18^2} \\\\ = \sqrt{1024 + 324} \\\\ = \sqrt{1348}[/tex]
Which gives result
= 36.7
or
= 37

A100
12
Answer:
x=0
Step-by-step explanation:
First, we distribute on both sides
6x+6-5x=8+2x-2
simplify
x+6=2x+6
subtract x from both sides
6=x+6
subtract 6 from both sides
x=0
(plz give brianliest ty)
Answer:
x = 0
Step-by-step explanation:
6 ( x + 1 ) -5x = 8 + 2 ( x - 1 ) (Distribute)
6x + 6 - 5x = 8 + 2x - 2 (Rearrange expression)
6x - 2x - 5x = 8 - 6 - 2 (Combine like terms)
-1x = 0 (Divide)

How many different five-card hands can be dealt from a standard deck of fifty-two cards?
Answer:
2598960 ways
Step-by-step explanation:
Given
Standard Deck = 52
Five-card hands
Required
Determine the number of ways
To solve this question, we make use of combination formula
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
Where n = 52 and r = 5
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex] becomes
[tex]^{52}C_5 = \frac{52!}{(52-5)!5!}[/tex]
[tex]^{52}C_5 = \frac{52!}{47!5!}[/tex]
[tex]^{52}C_5 = \frac{52 * 51 * 50 * 49 * 48 * 47!}{47! * 5 * 4 * 3 * 2 * 1}[/tex]
[tex]^{52}C_5 = \frac{52 * 51 * 50 * 49 * 48}{5 * 4 * 3 * 2 * 1}[/tex]
[tex]^{52}C_5 = \frac{311875200}{120}[/tex]
[tex]^{52}C_5 = 2598960[/tex]
Hence, there are 2598960 ways
Integral..Could you help me,please?
Answer:
as we know, the integral of [tex]x^{n}[/tex] is [tex]\frac{x^{n+1} }{n+1}[/tex]
so, the integral of x.[tex]2^{x}[/tex] will be found as follows:
here, we will use a trick called 'integration by parts'
let x = u and [tex]2^{x}[/tex] = v
∫uv dx = u∫v dx - ∫[(du/dx)* ∫v dx] dx
∫x.[tex]2^{x}[/tex] dx = x∫[tex]2^{x}[/tex] - ∫[(dx/dx) * ∫[tex]2^{x}[/tex] dx ] dx
∫x.[tex]2^{x}[/tex] dx = x*[tex]\frac{2^{x+ 1}}{x+ 1}[/tex] - 1 * [tex]\frac{2^{x + 1} }{x + 1}[/tex]
= [tex]\frac{2^{x} }{x + 1}[/tex]( x - 1 )

Area of the Region Between Curves-Please help.
Answer: 32/3
Step-by-step explanation:
To find the area of the region between the curves, you first want to find the interval of both curves. You can do that by setting both curves equal to each other.
[tex]-\frac{1}{2}x^2+2=\frac{1}{2} x^2-2[/tex] [subtract both sides by 2]
[tex]-\frac{1}{2}x^2= \frac{1}{2} x^2-4[/tex] [subtract both sides by [tex]\frac{1}{2} x^2[/tex]]
[tex]-x^2=-4\\x=2,-2[/tex]
Now that we know the interval, we set this into an integral and subtract the top curve by the bottom curve. *Note: I can't type in -2 into the interval, therefore only a "-" will be displayed.
[tex]\int\limits^2_- {|-\frac{1}{2}x^2+2-(\frac{1}{2}x^2-2) | } \, dx[/tex] [distribute -1]
[tex]\int\limits^2_-{|-\frac{1}{2}x^2+2-\frac{1}{2}x^2+2 |} \, dx[/tex] [combine like terms]
[tex]\int\limits^2_- {|-x^2+4|} \, dx[/tex] [solve integral]
[tex]\frac{32}{3}[/tex]
The area between the curves is 32/3. This was also the reason why we had the absolute values because area can never be negative.

If c(x)=5/x-2 and d(x)=x+3,. What is the domain of (CD)(x)
Answer:
all real numbers except x=2
Step-by-step explanation:
We assume you intend c(x) = 5/(x-2), rather than c(x) = (5/x) -2 as written.
__
The domain of c(x) is real numbers, excluding 2. Multiplying c(x) by d(x) doesn't change that.
The domain of (cd)(x) = c(x)×d(x) = 5(x+3)/(x-2) is "all real numbers except 2".
__
2 is excluded because c(x) is undefined for that value.
