Angelica the Alligator is laying our next to a perfectly circular pond. She is 9 feet from the edge of the pond and 15 feet from the point of tangency. Determine the radius of the pond.
9514 1404 393
Answer:
8 ft
Step-by-step explanation:
Consider the attached diagram.
The rule for secants and tangents tells us ...
(AC)(AB) = (AT)²
AC = AT²/AB = 15²/9 = 25
Then the diameter is ...
BC = AB - AC = 25 -9 = 16
The pond has a diameter of 16 ft, so a radius of 8 feet.
__
Additional comment
Since point C is the nearest point on the edge of the pond to point A, it must lie on line AO. Hence BC must be a diameter.

The perimeter of a rectangle is 90 centimeters. The length is 27 centimeters.
What is the width of the rectangle?
Answer: 18 cm
Step-by-step explanation:
the perimeter of a rectangle = 2 equal sides + 2 different equal sides
27cm + 27cm = 54cm
90cm - 54cm = 36cm
36cm/2 = 18 cm

A physical fitness association is including the mile run in its secondary-school fitness test. The time for this event for boys in secondary school is known to possess a normal distribution with a mean of 450 seconds and a standard deviation of 60 seconds. Find the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds. Group of answer choices
Answer:
0.0107 = 1.07% the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 450, \sigma = 60[/tex]
Find the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.
This is the pvalue of Z when X = 312. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{312 - 450}{60}[/tex]
[tex]Z = -2.3[/tex]
[tex]Z = -2.3[/tex] has a pvalue of 0.0107
0.0107 = 1.07% the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.

Step-by-step explanation:
Amy and Belinda each roll a sheet of 6-inch by 8-inch paper to form a cylindrical tube. Amy tapes the two 8-inch sides together without overlap. Belinda tapes the two 6-inch sides together without overlap. What is $\pi$ times the positive difference of the volumes of the two tubes
Answer:
ΔV = 24*π inches
Step-by-step explanation:
Amy Tube volume = V₁ the 6 inches sides will shape the circumference of area A₁ = π*r²
A₁ = π*(3)² and
V₁ = π*r²*h₁
V₁ = π*(3)²*8
V₁ = 72*π
In the case of Belinda, r will be 4 inches and h₂ = 6 and V₂
V₂ = A₂*h₂
V₂ = π*(4)²*6
V₂ = 96* π
Then differences of the volumes is
V₂ - V₁ = ΔV = 96*π - 72*π
ΔV = 24*π inches

Step-by-step explanation:
three coworkers decided to buy fruit to share at lunch time.Antonii spent $1.47 on bananas.Laura spent $2.88 on apples.Suzanne spent $2.85 on oranges.
If Laura bought 2.1 pounds of apples,is the price per pound of apples greater than or less than $1 ? how can you tell?
Answer:
The price per pound of apples is greater than $1.
Step-by-step explanation:
Please consider the complete question:
Three coworkers decided to buy fruit to share at lunch time. Antonii spent $1.47 on bananas.Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges. If Laura bought 2.1 pounds of apples, is the price per pound of apples greater than or less than $1 ? how can you tell?
To find the price of apples per pound, we need to divide total amount paid by Laura ($2.88) with total pounds of apples (2.1 pounds) bought.
Price of apple per pound = [tex]\frac{2.88}{2.1}[/tex]
Price of apple per pound = $1.37142857
Since the price of apples per pound is $1.37, therefore, the price per pound of apples is greater than $1.
We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1. So when we will divide 2.88 by 2.1, then we will get a number greater than 1.
Using unitary method, the price per pound of apples is greater than $1.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that three coworkers decided to buy fruit to share at lunch time. Antonii spent $1.47 on bananas.Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges. If Laura bought 2.1 pounds of apples, then
To determine the price of apples per pound, we need to divide total amount paid by Laura with total pounds of apples bought.
Price of apple per pound = 2.88/ 2.1
Price of apple per pound = $1.37142857
Since the price of apples per pound is $1.37, thus, the price per pound is greater than $1.
We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1.

I would appreciate it if you could answer the questions please- A ball is thrown upward at 48ft/s from a building that is 100 feet high the function h(t)= -16+84t + 100 expresses the balls height,h in feet given the time t, in seconds since the ball was thrown.please answer the questions if you know the answer I would appreciate it
Problem 8
Answer: 1.5 seconds----------------
Work Shown:
h(t) = -16t^2+48t+100 is the same as y = -16x^2+48x+100, just with different variables.
Compare this to y = ax^2+bx+c to find that a = -16, b = 48, c = 100
Then compute the x coordinate of the vertex -b/(2a) getting
h = -b/(2a)
h = -48/(2*(-16))
h = 1.5
It takes 1.5 seconds for the ball to reach its peak height. The vertex represents the max height since the parabola opens downward.
==============================================
Problem 9
Answer: 136 feet----------------
Work Shown:
Plug the result from problem 8 into the function
y = -16x^2 + 48x + 100
y = -16(1.5)^2 + 48(1.5) + 100
y = 136
The vertex is (1.5, 136)
This means at 1.5 seconds, the ball is 136 feet off the ground at its highest point.
==============================================
Problem 10
Answer: approximately 4.415 seconds----------------
Work Shown:
Plug in y = 0 and solve for x
y = -16x^2 + 48x + 100
0 = -16x^2 + 48x + 100
-16x^2 + 48x + 100 = 0
Apply the quadratic formula
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(48)\pm\sqrt{(48)^2-4(-16)(100)}}{2(-16)}\\\\x = \frac{-48\pm\sqrt{8704}}{-32}\\\\x \approx \frac{-48\pm93.29523032}{-32}\\\\x \approx \frac{-48+93.29523032}{-32}\ \text{ or } \ x \approx \frac{-48-93.29523032}{-32}\\\\x \approx \frac{45.29523032}{-32}\ \text{ or } \ x \approx \frac{-141.2952303}{-32}\\\\x \approx -1.41547593\ \text{ or } \ x \approx 4.41547595\\\\[/tex]
A negative x value makes no sense because time cannot be negative, so we ignore the first solution. The only practical solution is roughly x = 4.415
It takes approximately 4.415 seconds for the ball to reach the ground.
==============================================
Problem 11
2 Answers: At 0.5 seconds and at 2.5 seconds----------------
Work Shown:
Use the same idea as problem 10. Instead of y = 0, use y = 120
y = -16x^2 + 48x + 100
120 = -16x^2 + 48x + 100
-16x^2 + 48x + 100 = 120
-16x^2 + 48x + 100-120 = 0
-16x^2 + 48x - 20 = 0
-4(4x^2 - 12x + 5) = 0
4x^2 - 12x + 5 = 0
Now apply the quadratic formula
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-12)\pm\sqrt{(-12)^2-4(4)(5)}}{2(4)}\\\\x = \frac{12\pm\sqrt{64}}{8}\\\\x = \frac{12\pm8}{8}\\\\x = \frac{12+8}{8}\ \text{ or } \ x = \frac{12-8}{8}\\\\x = \frac{20}{8}\ \text{ or } \ x = \frac{4}{8}\\\\x = 2.5\ \text{ or } \ x = 0.5\\\\[/tex]
There are two moments in time when the ball is 120 feet in the air. Those two moments are at x = 0.5 seconds and at x = 2.5 seconds.
At x = 0.5, the ball is going upward. At x = 2.5, the ball is coming back down.
Answer:

Answer:
A
Step-by-step explanation:
The school band collected $3,240 for 380 tickets sold to their spring concert. Adult tickets were $12 each and student tickets were $6 each. How many adult tickets were sold?
160 adult tickets were sold
How to determine how many adult tickets were sold?Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.
Set up equations to represent the problem.
Let the A and S represent the number of adult and student ticket respectively. So we can write:
12A + 6S = 3,240 --- (1)
A + S = 380 --- (2)
From (2):
S = 380 - A ---- (3)
Put (3) in (1):
12A + 6S = 3,240
12A + 6 (380 - A) = 3,240
12A + 2280 -6A = 3,240
6A = 3,240 - 2280
6A = 960
A = 960/6
A = 160 tickets
Thus, the number of adult ticket sold is 160

Answer:
The value of x is 17.32
Step-by-step explanation:
It can clearly be seen that the triangle is a right-angled triangle.
In the triangle, according to reference angle 13 degree,
Base = 30
Perpendicular = x
We can use trigonometric ratios for finding the value of x
As tangent includes both perpendicular and base, we can use this.
So,
[tex]tan\ 30 = \frac{perpendicular}{base}\\tan\ 30 = \frac{x}{30}\\0.5773 = \frac{x}{30}\\x = 0.5773*30\\x = 17.319[/tex]
Rounding off to nearest hundredth
x = 17.32
Hence,
The value of x is 17.32
