Answer:
$290
Step-by-step explanation:
We can use the equation that Skate Land created to find the total cost
C = 7.50p + 65
p = people so if we have 30 people, we have to solve 7.50 x 30
C = 225 + 65
we can now add the flat fee of $65 to get the total cost for the birthday part
C = $290

A female rabbit can give birth to over 40 baby rabbits a year. Suppose all of her offspring survived and reproduced, all of their offspring survived and reproduced, and so on. If that happened, in only eight years the mass of rabbits would exceed the mass of Earth!

Help with this lesson. thank you for those who take the time to help me out.
Answer:
58 mi^2.
Step-by-step explanation:
We can split this up into 2 rectangles and 1 triangle.
Height of the triangle = 4 + 2 + (12-11)
= 7.
Total area
= 2*12 + 2*10 + 1/2 * 4 * height of the triangle
= 24 + 20 + 1/2 * 4 * 7
= 44 + 14
= 58 mi^2.

Answer:
HL (Hypotenuse-Leg)
x = 13
Step-by-step explanation:
hypotenuse GJ is shared by both triangles.
∠H and ∠K are right angles so they are right triangles.
leg HG = leg KG
so HL theorem
x + 5 = 8
x = 13
(Right angle, hypotenuse and side theorem)
By this theorem GK = GH ,
=> x + 5 = 8
=> x = 8-5
=> x = 3HOPE IT HELPS

if you subtract 17 from my number and multiply the difference by -6 the results is -138 what is Sarah's number
Answer:
40
Step-by-step explanation:
let the unknown be y (x is used as times(multiplication) )
(y-17)x-6=-138
add /-6 to both sides
y-17x-6/-6=-138/-6
y-17=23
make y independent/add 17 to both sides
y-17+17=23+17
y=40
or in an easier way
-138/-6 =23
23+17=40

Suppose that the effects of copper on a second species (say, species B) of fish show the variance of ln(LC50) measurements to be .8. If the population means of ln(LC50) for the two species are equal, find the probability that, with random samples of ten measurements from each species, the sample mean for species A exceeds the sample mean for species B by at least 1 unit.
Answer:
Hello the reference related to your question is missing attached below is the reference
answer : p ( x - y ≥ 1 ) = 0.0019
Step-by-step explanation:
Assuming 'X' and 'Y' are independent random samples
X : mean value = [tex]U_{1}[/tex] , variance = 0.4 /10 = 0.04
Y : mean value = [tex]U_{2}[/tex] , variance = 0.8/10 = 0.08
since the values are independent
V [ X - Y ] = V [ X ] + V [Y ] = 0.04 + 0.08 = 0.12
Determine the probability that the sample mean for species A exceeds the sample mean for species B by at least 1 unit
P ( x - y ≥ 1 ) = 0.0019
attached below is the detailed solution
Determine which equation has the same solutions as the given equation.
x2 − 10x − 11 = 0
A.
(x − 10)2 = 36
B.
(x − 5)2 = 36
C.
(x − 5)2 = 21
D.
(x − 10)2 = 21
I just want to mention that the question is wrongly written!
it's meant to be x² − 10x − 11 = 0 and not x2 − 10x − 11 = 0
and so the other equations!
Answer:
The answer is B: (x − 5)² = 36
Step-by-step explanation:
by solving the equations using the quadratic formula we found:
the solutions for x² − 10x − 11 = 0 | x = 11, -1
the solutions for A | x = 16, 4
the solutions for B | x = 11, -1
the solutions for C | x = [tex]\sqrt{21} +5[/tex], [tex]-\sqrt{21}+5[/tex]
the solutions for D | x = [tex]\sqrt{21}+10, -\sqrt{21}+10[/tex]
the given equation: x² − 10x − 11 = 0 and the equation B: (x − 5)² = 36 have the same solutions
Therfore B is the correct answer

Rob paid $50.15 for two pairs of jeans, which include a 15% discount.
What was the price of one pair of jeans before the discount was added?
Answer:
$29.50
Step-by-step explanation:
The price that Rob paid includes a 15% discount. This means that Rob paid 85% of the original price.
100% - 15% = 85%
Divide the price Rob paid by the percentage the price is of the total.
85% = 0.85
50.15/0.85 = 59
Now, divide the total price by 2 so that you can find the price of one pair of jeans.
59/2 = 29.50
The price of one pair of jeans is $29.50
The histogram shows the number of minutes that users waited to register for classes on a university's online system. According to the histogram, how many users waited more than a hour but not more than 2 hours?
A) 2
B) 8
C) 9
D) 11
Answer: the answer is 4
Step-by-step explanation:
11 users waited more than a hour but not more than 2 hours.
What is Histogram?A histogram is a graphical depiction of continuous or discrete data. In a histogram, the frequency is represented by the area of a bar. Frequency density, which is proportional to frequency, is plotted on the y-axis, and intervals representing the range of values are plotted on the x-axis.
From the Histogram we have
For 0 -30 minutes - 5 users wait
31- 60 minutes- 4 users wait
61- 90 minutes- 9 users wait
91- 120 minutes- 2 users wait
120- 150 - 4 users wait
So, the number of users waited more than a hour but not more than 2 hours
= 9 + 2
= 11 users

Which is the graph of the sequence defined by the function f(x + 1) = Three-fifthsf(x) when the first term in the sequence is 375?
On a coordinate plane, 4 points are plotted. The points are (1, 375), (2, 225), (3, 135), (4, 81).

On a coordinate plane, 4 points are plotted. The points are (0, 375), (1, 75), (2, 15), (3, 3).
Answer: On a coordinate plane, 4 points are plotted. The points are (1, 375), (2, 225), (3, 135), (4, 81).
Step-by-step explanation:
We have the relation:
f(x + 1) = (3/5)*f(x)
such that the first term is 375
Then:
f(1) = 375.
Using the above relation, we have that:
f(1 + 1) = f(2) = (3/5)*f(1) = (3/5)*375 = 225
Then we have the pair (2, 225)
The next term is:
f(2 + 1) = f(3) = (3/5)*f(2) = (3/5)*225 = 135
Then we have the pair (3, 135)
the next term is:
f(3 + 1) = f(4) = (3/5)*f(3) = (3/5)*135 = 81
Then we have the pair (3, 81)
Then the correct option is the first one; On a coordinate plane, 4 points are plotted. The points are (1, 375), (2, 225), (3, 135), (4, 81).

The ticket sales at a movie theater were $6,569. Adult tickets are $12, and senior tickets are $11. The
number of senior tickets sold was 21 less than twice the number of adult tickets. Determine the
number of adult tickets and senior tickets sold.
They sold
adult tickets.
They sold
senior tickets.
Answer:
12x + 11y = 6569 (X is adult ticket, Y is senior ticket)
Y = 2x - 21
Now to plug it in:
12x + 11(2x-21) = 6569
12x+22x-231 = 6569
34x = 6569 + 231 = 6800
34x = 6800
x = 200
y = 379
200 adult tickets were sold and 379 senior tickets were sold.
