In 2020, summer camp registration was $15
more than it was in 2021. In 2020, registration
was $285. By what percentage did the summer
camp registration decrease in 2021?
Answer:
I think your answer is 5.25% or it could be 5.3 or 5
5.26 percent of the summer camp registration decreased in 2021
What is the percentage?The ratio of two numbers that has no dimensions is what is known as a percentage. It may be used to determine how much one number exceeds another when comparing two figures, or it is used to compare the two statistics to a uniform grid.
In 2020, there was a $285 membership fee for summer camp.
It is stated that the membership cost for summer camp increased by $15 in 2020 compared to 2021. We can calculate the summer camp registration cost for 2021 using the data given.
In 2021, there was a $285-$15 membership fee for summer camps.
there was a $270 membership fee for summer camps.
The gradual decrease in the summer enrichment registration price must be determined = (Drop/Initial Value)*100 represents the proportion decrease.
= (15/285)*100 represents the percentage decline.
The membership price for summer camps has decreased by 5.26 percent.

Step-by-step explanation:
Substitute given value into function and evaluate
Answer:
-94.94
Step-by-step explanation:
The answer is -94.94. First you put -4.2 as x, so 23.2*-4.2 which gives you -97.44. Then you do (-97.44)+22.5. Which gives you the answer -94.94.
Bri and Annamarie are picking strawberries at two different strawberry farms that charge a flat fee plus a cost per basket picked. The graph shows the total cost for Annamarie based on the number of baskets of strawberries picked.
The equation y = 3.25x + 5.5 shows the total cost for Bri with y representing the cost and x representing the number of baskets picked.
Which statements about the baskets picked by the two girls are true? Select each correct answer.
A) The farm where Bri picks charges less of a flat fee.
B) The farm where Bri picks charges less per basket picked.
C) Annamarie pays $2.75 per basket picked.
D) Bri pays $5.50 per basket picked.
The points on the graph for the amount of strawberries picked by Annamarie are (0, 11), (10, 38.5).
(10, 38.5)
38.5/10 = 3.85
Annamarie pays $3.85 per basket.
y = 3.25x + 5.5
(3.25, 5.5)
The amount of strawberries picked by Bri is (3.25, 5.5).
Bri pays $5.50 per basket.
The farm where Bri chose to pick strawberries charges more for them so A and B are not the answer.
Annamarie pays $3.85 per basket so C is not one of the answers.
The only answer is D) Bri pays $5.50 per basket picked.Answer:

Krista’s mom has told her she need to make the pen 21 the size that she had planned (5 feet long by 4 21 feet wide). What will the area be? What are two possible lengths and widths she could use?.
The area of Krista’s mom new pan is 11 1/4 ft² and two possible dimensions are (5 , 4 1/2) and (4 1/2 , 2 1/2)
What is the area of a rectangle?Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,
[tex]A=a\times b[/tex]
Here, (a)is the length of the rectangle and (b) is the width of the rectangle
The dimensions of pan which, Krista’s mom, had planned is 5 feet long by 4 1/2 feet wide. Therefore, the length of the pen is 5 feet and the width of the pan is 4 1/2 feet.
Thus, the area of this rectangular pan is,
[tex]A=5\times4\dfrac{1}{2}\\A=5\times\dfrac{9}{2}\\A=22\dfrac{1}{2}\rm ft^2[/tex]
The area of the pan is 22 1/2 ft².
Now, Krista’s mom has told her she needs to make the pen 1/2 the size. Thus the area of new pan is,
[tex]A=\dfrac{22\dfrac{1}{2}}{2}\\A=\dfrac{\dfrac{45}{2}}{2}\\A=\dfrac{45}{4}}\\A=11\dfrac{1}{4}}\\[/tex]
For this area, possible dimensions are 4 1/2 and 2 1/2.
Hence, the area of Krista’s mom new pan is 11 1/4 ft² and two possible dimensions are (5 , 4 1/2) and (4 1/2 , 2 1/2)

r =
-1/4
Approximate the sum of the first 17 terms to the nearest tenth.
Sum =
-204.8
Step-by-step explanation:
The value [tex]a_1[/tex] is -256.
The value r = -1/4
What is a geometric sequence?A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
Example:
2, 4, 8, 16 is a geometric sequence.
We have,
In a geometric sequence,
Each term is obtained by multiplying the preceding term by a constant factor, which is called the common ratio (r).
So,
The nth term of the sequence.
[tex]a_n[/tex] = -256 x [tex](-1/4){n-1}[/tex]
Now,
[tex]a_1[/tex] = -256 x [tex](-1/4)^{1 -1}[/tex]
= -256 [tex](-1/4)^0[/tex]
= -256 x 1
= -256
[tex]a_2[/tex] = -256 x [tex](-1/4)^{2-1}[/tex]
= -256 x [tex](-1/4)^1[/tex]
= -256 x -1/4
= 64
Now,
[tex]a_1[/tex] r = [tex]a_2[/tex]
-256 x r = 64
r = 64 / -256
r = -1/4
Therefore,
[tex]a_1[/tex]= -256 and r = -1/4

The area of a circle is 61.2cm2.
Find the length of the radius rounded to 2 DP.
Answer:
4.41 cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
61.2 = pi r^2
Using 3.14 for pi
61.2 / 3.14 = r^2
19.49044586 = r^2
Take the square root of each side
sqrt( 19.49044586) = sqrt(r^2)
4.414798507 = r
To 2 decimal places

(3x-8)+(2x+6)=98 we can solve for x
after solving this we find that
x=20
Now we can solve for angle QRS
2x+6 plug in our values and we get

Can you please simplify these expressions in two forms: radical and simplified without exponents?
I don't really understand how fractional exponents work, so an explanation would be appreciated.
27^4/3
36^3/2
(1/8)^2/3
128^5/7
Thank you :)
Answer:
(a.) 27^4/3 = 81, (b.) 36^3/2 = 216, (c.) (1/8)^2/3 = 1/4, (d.) 128^5/7 = 32
Step-by-step explanation:
All these expressions can be converted in square roots.
In order to do this, we can picture the fractional exponents as exponent / index
(a.) So for this first problem, we would have the cube root of [tex]27^{\frac{4}{3} }[/tex] or
[tex]\sqrt[3]{(27)^{4} }[/tex].
We must do the equation inside the radical first (i.e., [tex](27)^{4}[/tex]) to get [tex]\sqrt[3]{531,441}[/tex] = 81
We can follow these same steps for the remaining equations:
(b.) [tex]36^{\frac{3}{2} }[/tex] = [tex]\sqrt{(36)^3}[/tex] = [tex]\sqrt{46,656}[/tex] = 216
(c.) [tex](\frac{1}{8})^\frac{2}{3}[/tex] = [tex]\sqrt[3]{(\frac{1}{8})^{2} }[/tex] = [tex]\sqrt[3]{(\frac{1^2}{8^2}) }[/tex] = [tex]\sqrt[3]{(\frac{1}{64}) }[/tex] = [tex]\frac{1}{4}[/tex]
(d.) [tex]128^{\frac{5}{7} }[/tex] = [tex]\sqrt[7]{(128)^{5} }[/tex] = 32

Answer:
i) 134
ii) Number of bottles sold on Tuesday: [tex]\dfrac{x}{45}[/tex]
iii) Number of bottles sold on Wednesday: [tex]\dfrac{(x-75)}{48}[/tex]
iv) [tex]x=3915[/tex]
Therefore, 87 bottles were sold on Tuesday and 80 bottles were sold on Wednesday
Step-by-step explanation:
i) You need to ensure that the values are both in the same format (either both in dollars, or both in cents).
45 cents = 45/100 dollars = 0.45 dollars
60.30 ÷ 0.45 = 134
ii) both values are in cents, so no need to convert one of them.
Let n be the number of bottles sold.
So 45n = x
Therefore, n = x/45
ii)
Let n be the number of bottles sold.
So 48n = (x - 75)
Therefore, n = [tex]\dfrac{(x-75)}{48}[/tex]
iv)
Number of bottles sold on Tuesday: [tex]\dfrac{x}{45}[/tex]
Number of bottles sold on Wednesday: [tex]\dfrac{(x-75)}{48}[/tex]
If the number of bottles sold on Tuesday was 7 more than those sold on Wednesday:
[tex]\implies \dfrac{x}{45}-7=\dfrac{(x-75)}{48}[/tex]
multiply both sides by 48:
[tex]\implies \dfrac{48x}{45}-336=x-75[/tex]
multiply both sides by 45:
[tex]\implies 48x-15120=45x-3375[/tex]
[tex]\implies 3x=11745[/tex]
[tex]\implies x=3915[/tex]
Therefore, 87 bottles were sold on Tuesday and 80 bottles were sold on Wednesday
