Answer:
39
Step-by-step explanation:
Let h: hit
Let n: not hit
1) We can create two equations and solve them simultaneously using the substitution method or elimination.
h + n = 100
12h - 4n = 224
2) Solve them. I will demonstrate using the substitution method.
n = 100 - h
-----------------------
12h - 4(100 - h) = 224
12h - 400 + 4h = 224
16h = 224 + 400
16h = 624
h = 624/16
h = 39
3) Substitute the result into one of the equations above.
n = 100 - 39
n = 61
Since the question wants you to write the number of times the dragon was hit, the answer is 39.

Answer:
38 ft²Step-by-step explanation:
You can take it as combination of two figures, a trapezoid and a triangle.
Trapezoid has bases 12 ft and 8 ft and height 3 ft
Its area is
A = 1/2(8 + 12)(3) = 30 ft²Triangle has height 4 ft and base 4 ft,
Its area is
A = 1/2(4*4) = 8 ft²Total area is
30 + 8 = 38 ft²Mya and Ashley are buying tickets to the art show. Adult
tickets cost $3 more than the student tickets. Mya buys 7
tickets and 6 adult tickets. Ashley buys 15 student tickets and
1 adult ticket. They both spend the same amount of money
on their tickets. What is the price of one adult ticket?
Answer:
$8
Step-by-step explanation:
a: adult tickets
s: student tickets
Mya: 7s + 6(3+s)
Ashley: 15s + 1(3+s)
Mya: 7s + 6(3+s) –> 7s + 18 +6s –> 13s +18
Ashley: 15s + 1(3+s) –> 15s + 3 + s –> 16s +3
13s + 18 = 16s +3
15 = 3s, divide 3 from both sides so s = 5
so students tickets cost $5
since adult tickets cost $3 more than student tickets:
($3 + $5) = $8 for an adult ticket.
Answer:
the answer is $8

What is the value of x?
Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
15x + 3 + 3x - 1 + 52 = 180
15x + 3x + 3 - 1 + 52= 180
Combine like terms.
18x + 54 = 180
To find the vlaue of x, we have to islolate x
Step1: Subtract 54 from both sides
18x = 180 - 54
18x = 126
Step2: Divide both sides by 18
x = 126/18
x = 7
Answer:
x = 7 degrees
Step-by-step explanation:
See attached image.
If someone answers this question, the next one i'll ask with be 100 points

About 50 cane toads were introduced into Australia in 1935 to try to control the population of beetles that destroy sugar cane plants. By 2005, there were an estimated 100,000,000 cane toads in Australia. An exponential function that models the number of female cane toads in Australia t years after 1935 is given by f(t)=50(1.23)t .
a. Write a linear function p that models the number of cane toads in Australia t years after 1935. p(t)=_____
b. Describe the parameters in the exponential function, , in terms of the context of the problem. ____
c. Describe the parameters in the linear function, p , in terms of the context of the problem. ____
Question 4 d. Which model do you think is more appropriate to model the female cane toad population? Use the parameters of the functions to justify your reasoning. Linear or exponential?
Predict the population of female cane toads in Australia in 2000 based on each function. The linear function predicts that there would be ___ female cane toads in 2000. The exponential function predicts that there would be ___ female cane toads in 2000.
The linear function predicts that there would be 92857146 female cane toads in 2000 while the exponential function predicts that there would be 34898137 female cane toads in 2000.
Part A: The linear model of the number of cane toadsFrom the question, we have the following points
(t, f(t)) = (0,50) and (70, 100000000)
The linear function is then calculated as:
f(t) = [f(t2) - f(t1)]/[t2 - t1](t - t1) + f(t1)
This gives
f(t) = [100000000 - 50]/[70 - 0](t - 0) + 50
Evaluate
f(t) = 1428570.71t + 50
Hence, the linear function is f(t) = 1428570.71t + 50
Part B: The parameters in the exponential functionThe exponential function is given as:
f(t) = 50(1.23)^t
So, the parameters are:
50 represents the initial value1.23 represents the ratet represents the number of years from 1935f(t) represents the number of cane toad in year tPart C: The parameters in the linear functionThe exponential function is calculated as:
f(t) = 1428570.71t + 50
So, the parameters are:
50 represents the initial value1428570.71 represents the ratet represents the number of years from 1935f(t) represents the number of cane toad in year tPart D: The appropriate modelWhen the population of an entity is being model, it is best to use the exponential model, because the populations would grow exponentially for some time, and then stop growing at some point
Hence, the more appropriate model is the exponential model.
Part E: The number of female cane toads in 2000
The year 2000 is 65 years from 1935.
So, we have:
t = 65
For the exponential model, we have:
f(t) = 50(1.23)^t
The equation becomes
f(65) = 50(1.23)^65
Evaluate
f(65) = 34898137
For the linear function, we have:
f(t) = 1428570.71t + 50
The equation becomes
f(65) = 1428570.71 * 65 + 50
Evaluate
f(65) = 92857146
This means that. there would be 34898137 female cane toads in 2000 according to the exponential function.

Simple interest[tex]\sf Formula:A = P(1 + rt)[/tex]
where:
A = final amountP = principalr = interest rate (in decimal form)t = time (in years)Given:

In January 2015, the Pew Research Center reported results from one of their surveys. "Asked about whether vaccines for childhood diseases such as measles, mumps, rubella (MMR) and polio should be required or left up to parental choice, 68% of adults say such vaccines should be required while 30% say that parents should be able to decide whether or not to vaccinate their children. "
The following is an excerpt from the press release:
The survey of the general public was conducted using a probability-based sample of the adult population by landline and cellular telephone Aug. 15-25, 2014, with a representative sample of 2,002 adults nationwide. The margin of sampling error for results based on all adults is plus or minus 3. 1 percentage points. What is 95% confidence interval for these findings
Considering the margin of error, it is found that the 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).
What is a confidence interval?
It is given by the sample statistic plus/minus the margin of error.
In this problem, 68% of adults say such vaccines should be required, with a margin of error of 3.1%, hence:
68% - 3.1% = 64.9%.
68% + 3.1% = 71.1%.
The 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).

Matt wants to start zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint? Use specific numbers from the situation to justify or refute whether Matt’s design meets the slope constraint
There is no difference in height that is not sufficient to meet the slope constraint if Matt wants to start a zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
We know the slope can be evaluated using:
[tex]\rm Slope = \frac{Change \ in \ y \ axis}{Change \ in \ x \ axis}[/tex]
Change in y-axis = difference in height
Change in y-axis = 16 - 10
= 10 feet
Change in x-axis = distance between tress
Since the data is not given.
So, the height difference is insufficient to keep the slope constraint.
Thus, there is no difference in height that is not sufficient to meet the slope constraint if Matt wants to start a zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint.

Solve using the Elimination Method
5x + y = 4
6x - y = 7
Answer:
x=1,y=-1
Step-by-step explanation:
To use the elimination method, we make the coefficient of y the same:
But they are already the same just with different signs.
So we add the 2 equations to make equation 3:
5x + y = 4
+ + = +
6x - y = 7
11x = 11
Solve for x:
x = 1
Substitute the value of x into either equation 1 or 2 to find y:
I chose 1:
5(1)+y=4
5+y=4
y=4-5
y=-1
Our answer is x=1,y=-1
Substituting these values into equation 2 verifies our answer
