You are going to an amusement park over Spring Break. The cost of admission to enter the park is $30 and the rides are an additional $6 each. If your parents give you $100 to spend at the amusement park, what is the maximum number of rides you can go on? Write an inequality to show the maximum number of rides you can go on.
Answer:
30+6x ≤ 100 (inequality)
The maximum amount of rides is 11 rides
Step-by-step explanation:
So first the admission fee is 30
Each ride is 6
So since you can go on any amount of rides, its unknown so (x)
You only have a 100 dollars and you can’t go over but you can go lower
so 30+6x≤100
If you solve it
x≤11
So 11 rides

A = {3, 5, 7, 9} and B = {1, 2, 4, 6, 7, 9}
Find the intersection: A Intersects withB.
{7, 9}
{1, 2, 3, 4, 5, 6, 7, 9}
{1, 3, 5}
{2, 4}
Answer:
A∩B={7,9}
Option A is correct option.
Step-by-step explanation:
We are given:
A = {3, 5, 7, 9} and B = {1, 2, 4, 6, 7, 9}
and we need to find A intersects with B i.e. A∩B
We find A intersects with B, we will consider only those terms that are common in both A and B
So,
A∩B= {3, 5, 7, 9} ∩ {1, 2, 4, 6, 7, 9}
As 7 and 9 are only common in both A an B
A∩B={7,9}
So, we get: A∩B={7,9}
Option A is correct option.

the base Dimensions of a rectangular box are 1.5×10 to the second power centimeters by 4.3×10 to the first power centimeters find the base area of the box right answer and say scientific notation and round coefficients to the nearest
Answer:
[tex]Area = 6.5 * 10^3cm^2[/tex] or [tex]Area = 6.5E3\ cm^2[/tex]
Step-by-step explanation:
Given
[tex]Width = 1.5 * 10^2cm[/tex]
[tex]Length = 4.3 * 10^1cm[/tex]
Required
Determine the Area
The base area is calculated as:
[tex]Area = Length * Width[/tex]
[tex]Area = 1.5 * 10^2cm * 4.3 * 10^1 cm[/tex]
Reorder the expression
[tex]Area = 1.5 * 4.3 * 10^1 cm* 10^2cm[/tex]
[tex]Area = 6.45 * 10^1 cm* 10^2cm[/tex]
Apply law of indices
[tex]Area = 6.45 * 10^{1+2}cm^2[/tex]
[tex]Area = 6.45 * 10^3cm^2[/tex]
Approximate
[tex]Area = 6.5 * 10^3cm^2[/tex]
or
[tex]Area = 6.5E3\ cm^2[/tex]

For what value of the number k is the following function differentiable at x=2
f(x) = {2x + 1 if x<2
k x=2
3x-1 x>2}
Answer:
For f(x) to be differentiable at 2, k = 5.
Step-by-step explanation:
For f(x) to be differentiable at x = 2, f(x) has to be continuous at 2.
For f(x) to be continuous at 2, the limit of f(2 – h) = f(2) = f(2 + h) as h tends to 0.
Now,
f(2 – h) = 2(2 – h) + 1 = 4 – 2h + 1 = 5 – 2h.
As h tends to 0, lim (5 – 2h) = 5
Also
f(2 + h) = 3(2 + h) – 1 = 6 + 3h – 1 = 5 + 3h
As h tends to 0, lim (5 + 3h) = 5.
So, for f(2) to be continuous k = 5

Consider WXY and BCD with X= C, WX = BC, and WY = BD. Can it be concluded that WXY = BCD by SAS?
Answer:
nswer:- B. No, because the corresponding congruent angles listed are not the included angles. Given:- ΔWXY and ΔBCD with ∠X ≅∠C, WX ≅ BC, and WY ≅ BD. We can see that ∠X and ∠C are not included angles by the corresponding equal sides.
Answer:
Yes
Step-by-step explanation:
I will write it in the form of a theorem
Given:
X=C; WX=BC;WY=BD
To prove:
WXY = BCD
Proof:
X=C (This is a angle)
WX=BC
WY=BD
Since there is an angle between two equal side for both triangle WXY is congruent or '=' BCD ny SAS.
Today the price of a Jeep is $25,000. In 1970, the price was $5,000. What's the price relative?
Answer:
$500
Step-by-step explanation:
Today the price of a Jeep is $25,000.
In 1970, the price was $5,000.
We need to find the relative price. It can be calculated as follows :
[tex]P=\dfrac{25000}{5000}\times 100\\\\P=\$500[/tex]
So, the relative price is $500.

Q1:The number of students in a chess club decreased from 23 to 13. What is the percent decrease? Round your answer to the nearest percent.
The percent decrease is ? %.
Q2:The price of a pair of shoes increases from $68 to $81. What is the percent increase to the nearest percent?
The percent increase is ? %.
Answer:
Step-by-step explanation:
23 x .565 = 12.995
12.995 rounded is 13.
So if the answer is .565, and you need to round to the nearest percent, it would be 57%.
Answer:
Step-by-step explanation:
1) Decreased students = 23 -13 = 10
Decreased percentage = [tex]\frac{10}{23}*100[/tex]
[tex]= \frac{1000}{23}\\\\= 43.47[/tex]
= 43%
2) Increased amount = 81 - 68 = $ 13
Increased percentage = [tex]\frac{13}{68}*100[/tex]
[tex]= \frac{1300}{68}\\\\= 19.11[/tex]
= 19%

Answer:
B. 25√3
Step-by-step explanation:
Use trigonometric ratio formula to find the length and width of the rectangle
Thus:
✔️Length of diagonal:
Reference angle = 30°
Hypotenuse = 10
Let length of rectangle = x = adjacent side
Therefore:
Cos 30° = x/10
10*cos 30 = x
10*√3/2 = x (cos 30 = √3/2)
5√3 = x
x = length of rectangle = 5√3
✔️Width of diagonal:
Reference angle = 30°
Hypotenuse = 10
Let width of rectangle = y = opposite side
Therefore:
Sin 30° = y/10
10*sin 30 = y
10*½ = y (sin 30 = 1/2)
5 = y
y = width of rectangle = 5
✔️Area of rectangle = length * width = 5√3 * 5 = 25√3
