Step-by-step explanation:
You have the stand alone value of 17.5 for parking. You can subtract this from the total as shown in the equation. If each admission costs $24 then it would be 24x for the remainder. Therefore you can write the equation as 113.5 - 17.5 = 24x.
Please help with the following questions!
Answer:
7.) y= 4x - 5
8.) y= -4/3x + 1
9.) y= -1x + 3 or y= -x + 3
10.) y= 5/4 + 0 but it can also be written as y=5/4
11.) y= -2x - 10
12.) y= 1.5x + 1.5

A corner shelf is in the shape of a triangle. One side measures \(2x^2 + 2x -1\) while another side measures \(5x + x^2 - 3\)
What is the total of two sides? Show all work.
If the perimeter measures\(3x^3 - x^2 - 8x +1\) what is the length of the missing side? Show all work.
If we know that \(x =2\) then what are the lengths of the three sides of the triangle? Show all work.
Is it possible to have these side lengths? Why or why not?
1.The total of two sides is: $6 + 8 = 14$.
2.The missing side has a length of 4.
3.All three inequalities are true, so these side lengths do form a valid triangle.
4. It is not possible to have side lengths.
1. To find the total of two sides of the triangle shelf, we simply add the two given side measurements together.
2. $Perimeter = a + b + c$ where a, b, and c are the lengths of the three sides of the triangle. We are given that the perimeter measures 18, and we know that 6 and 8 are two of the sides, so we can substitute these values into the formula to solve for c:
$18 = 6 + 8 + c$
$18 - 14 = c$
$4 = c$
3. If we know that $a$ = 3, $b$ = 5, and $c$ = 8, we can check if these side lengths form a valid triangle by using the triangle inequality theorem, Therefore, we need to check if:
$a + b > c$
$b + c > a$
$a + c > b$
Substituting in the given values, we get:
$3 + 5 > 8$ (True)
$5 + 8 > 3$ (True)
$3 + 8 > 5$ (True)
4. of $a$ = 2, $b$ = 4, and $c$ = 7 for a triangle. The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side. If we apply this to the given values, we get:
$a + b > c$
$2 + 4 > 7$ (False)

A tropical species of mite named Archegozetes longisetosus is the record holder for the strongest insect in the world. It can lift up to 1.182 × 103 times its own weight. If a person who weighed 100 pounds were as strong as this insect, how much could that person lift? Enter the answer using scientific notation.
Answer:
The first thing we have to do is to measure your weight using a weighing scale.
Suppose your weight is 130 pounds, therefore you can lift:
130 pounds * 1.182 • 10^3 = = 153,660 pounds or 1.537 x 10^5 pounds

Step-by-step explanation:
Find the missing number so that the equation has infinitely many solutions. – 5x–19= (Blank)x–19
Answer:(number)=-5
Step-by-step explanation:
You can use simple logic in order to solve this equation.
An equation that has infinitely many solutions will have the same exact numbers on both sides
Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true
The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

Step-by-step explanation:
A click beetle abruptly releases elastic energy stored in its body to launch itself into the air. The function h(t)=−16t^2+8t represents the height h (in feet) of the click beetle t seconds after launching. The height of a second click beetle t seconds after launching is shown in the graph. Which click beetle went higher?
Answer:
The first click beetle went higher.
Step-by-step explanation:
The vertex is the minimum point of a parabola that opens upwards, or the maximum point of a parabola that opens downwards.
Since the height of each of the beetles at time, t seconds, is modelled as a parabola that opens downwards, the maximum height of each beetle is the y-value of the vertex.
First Click BeetleThe function representing the height, h, of the first beetle is:
\(h(t)=-16t^2+8t\)
We could complete the square to rewrite the function in vertex form, however the quickest way to find the vertex of a quadratic function in the form ax² + bx + c is to use the formula for the x-value of the vertex:
\(\boxed{x_{\sf vertex}=-\dfrac{b}{2a}}\)
Comparing ax² + bx + c with the given function:
a = -16b = 8c = 0Therefore, substituting the values of a and b into the formula, the x-value of the vertex of h(t) is:
\(x_{\sf vertex}=-\dfrac{8}{2(-16)}=0.25\)
To find the y-value of the vertex, and thus the maximum height of the first beetle, simply substitute t = 0.25 into function h(t):
\(\begin{aligned}\implies h(0.25)&=-16(0.25)^2+8(0.25)\\&=-16(0.0625)+2\\&=-1+2\\&=1\end{aligned}\)
Therefore, the maximum height of the first beetle is 1 foot.
Second Click BeetleFrom inspection of the given graph modelling the height of the second beetle, we can see that the maximum y-value is approximately 0.76 feet.
ConclusionAs the height of the second click beetle is less than the maximum height of the first click beetle, the first beetle went higher.

Darlene wants to buy a sweater that originally cost $48. It is on sale for 35% off. Sales tax is 8%. What is the final price of the sweater with tax?
$28.70
$47.73
$33.70
$56.16
Answer:
$33.70
Step-by-step explanation:
The sweater costs $48. It is on sale for 35% off. The sales tax is 8%. We want to know the final price.
We know that 35% is the same as 0.35. We are going to multiply $48 by 0.35. This results in $16.80. The 35% is 35% off, so we are going to subtract $16.80 from the $48. This gives us $31.20. Now, we still have the 8% sales tax. 8% is the same as 0.08. We will multiply this by $31.20. This gives us $2.496, which we can round to $2.50. That is how much the sales tax is. It will be added to the price of the sweater. The result is $33.70.
Answer: I'd say you can eliminate option 56.16 and maybe go with 33.70

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night, the theater makes $1,512 from popcorn sales and $1,584 from nacho sales. If on the next night the employees sell $1,848 of popcorn, how much is earned from nachos?
Answer:
Using proportions, it is found that $1,225 is earned from nachos.
This question is solved by proportions, using a rule of three.
The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?
The rule of three is:
$1,540 - $1,330
$1,672 - $x
Applying line multiplication:
$1,225 is earned from nachos.

Rewrite the expression c + 0.25c as a single term with a fractional coefficient.
please help (No spam) (No stu-pid answers please)
Answer:
5c/4
Step-by-step explanation:
c = c × 1
0.25c = 0.25c × 1
c + 0.25c
Take " c " common.
= c × (1 + 0.25)
= c × 1.25
Convert 1.25 into a simpler fraction
1.25
= 125/100
= 5/4
c × 1.25
= c × 5/4
= (c × 5)/4
= 5c/4
The fractional coefficient is (5c/4)
What is a coefficient?A coefficient is a number or any symbol representing a constant value that is multiplied by the variable of a single term
Given:
\(\sf c+0.25c\)
\(\sf =(1+0.25)c\)
\(\sf =(1.25)(c)\)
\(\sf =1.25c\)
\(\sf =\dfrac{125}{100}\)
\(\sf =\dfrac{5}{4}\)
\(\sf =\dfrac{5c}{4}\)
Hence the fractional coefficient is (5c/4)
