A window that is in the shape of a semicircle has a diameter of 28inches. find the area of the window. Round to the nearest tenth
Final answer:
The area of the semicircle shaped window is approximately 307.7 square inches when rounded to the nearest tenth.
Explanation:
The student has asked to find the area of a window in the shape of a semicircle with a diameter of 28 inches. To calculate the area of a semicircle, we first find the radius of the full circle, which is half the diameter, and then apply the formula for the area of a circle, A = πr², before halving it since we want the area of a semicircle.
Find the radius (r) of the semicircle: r = diameter/2 = 28 inches / 2 = 14 inches.
Calculate the area of the full circle: A = πr² = π * (14 inches)².
Halve the area to get the semicircle's area: Semicircle area = A/2.
Using the value of π as 3.14 and rounding to the nearest tenth: Semicircle area ≈ (3.14 * [tex](14)^2[/tex])/2 = (3.14 * 196)/2 = 307.72 inches².
Hence, the area of the semicircle shaped window is approximately 307.7 square inches when rounded to the nearest tenth.

(a) In the first game recorded, the coach wrote 60%, or 54 pitches, were strikes. Find the total number of pitches Haruto threw in this game.
(b) In the second game recorded, the coach recorded 40%, or 34 pitches, were balls. Find the number of strikes and the total number of pitches he threw in this game.
Answer:
Yared takes 15 minutes to wrap 3 presents, and Luke takes 20 minutes to wrap 5 presents.
I divided 15 by 3 to get 5, and did the same with Luke, and I got 4. Both boys have a total amount of 20 presents to wrap, so I multiplied 5 by 20, to get 100, and I multiplied 4 by 20, and got 80.
I subtracted 100 by 80, and got a 20. Since I am finding information for Yared, I’m going to use 5, I divided 20 by 5, and got 4.
(b) Yared still needs to wrap 20% of his presents when Luke has finished wrapping presents.
Since the total amount of
presents to wrap is 20, I divided that by the total amount of presents that
Yared still needs to finish wrapping, which is 4. 4 divided by 20 is 0.2, and I
multiplied 0.2 by 100, 100 is the whole, and I got 20.
2. (a) 50 people said their favorite color was red.
Since there is 250 people in total, I used the percentage of the color red, which is 20%, and multiply it by 250. 20 divided by 100 is 0.2, and I multiply 0.2 by 250, which got me 50.

if ABC and GEF are congruent by the ASA criterion, which pair of angles must be congruent
The pair of angles that must be congruent for the given pair of congruent triangles are ∠CAB and ∠GEF.
The ASA criterion states that two triangles are congruent if two angles and the included side of one triangle are equal to the two angles and the included side of the other triangle.
In the figure, we have:
∠ABC = ∠GEF (given)
∠ACB = ∠EGF (included angles)
AC = EG (included side)
Therefore, by the ASA criterion, triangles ABC and GEF are congruent.
The other possible pairs of congruent angles are:
∠ACB and ∠FEG
∠CAB and ∠EGF
∠ABC and ∠GFE
However, none of these pairs of angles are included angles.
Therefore, the only pair of congruent angles that must be congruent is ∠CAB and ∠GEF.

How does the volume of a cone change if its radius and height are both tripled? A. B. C. D.
The volume of the cone changes by a factor of 27
How does the volume of the cone change
From the question, we have the following parameters that can be used in our computation:
Volume of a cone
The volume of a cone is calculated using
[tex]V = \frac13\pi r^2h[/tex]
When the radius and height are both tripled, we have
R = 3r
H = 3h
So, the new volume is
[tex]V_2 = \frac13\pi R^2H[/tex]
Substitute the known values into the equation
[tex]V_2 = \frac13\pi (3r)^2 * 3h[/tex]
Evaluate
[tex]V_2 = \frac13\pi 9r^2 * 3h[/tex]
So, we have
[tex]V_2 = \frac13\pi r^2h * 27[/tex]
Recall that
[tex]V = \frac13\pi r^2h[/tex]
So, we have
[tex]V_2 = 27V[/tex]
This means that the volume of the cone changes by a factor of 27

circle O has a circumference of 132 feet. what is the approximate area of the circle?
You can use the given circumference of 132 feet to find the radius using the formula C=2πr. Once the radius is found to be approximately 21 feet, use the formula for the area of a circle, being A=πr², to calculate an area of approximately 1386 square feet.
Explanation:To find the area of a circle when you know the circumference, you can use the formula for the circumference of a circle, which is C = 2πr (C is the circumference and r is the radius). From the circumference, we can find the radius.
Let's rearrange the formula for r: r = C / 2π . Plugging in the given value, r = 132 / 2π approximately equals 21 feet.
Next, we use the area of a circle formula A = πr² and plug in the radius to calculate the area. Here, A = π * (21)^2 that gives us an area of approximately 1386 square feet.

A bicyclist was traveling from the village to the railroad station with a speed of 15 mph and he was coming back to the village with a speed of 10 mph. Find the distance from the village to the railroad station, if it’s known that it took 1 more hour for the bicyclist to get back to the village.
Since, a bicyclist was traveling from the village to the railroad station with a speed of 15 mph and he was coming back to the village with a speed of 10 mph.
Let the time taken in traveling from village to the railroad station be 't' hours
Distance is calculated by the formula:
[tex] d= s \times t [/tex]
So, the distance traveled from village to the railroad station is:
[tex] d=15 \times t [/tex]
Since, the time taken in traveling from railroad station to the village is 1 hour more = 't+1' hours
So, the distance traveled from railroad station to the village is:
[tex] d=10 \times (t+1) [/tex]
Therefore, distance traveled from village to railroad station is equals to the distance traveled from railroad station to the village.
So, [tex] 15 \times t=10(t+1) [/tex]
[tex] 15t=10t+10 [/tex]
[tex] 5t=10 [/tex]
So, t=2
Therefore, distance from village to railroad station = [tex] 15 \times t [/tex]
= [tex] 15 \times 2 [/tex]
= 30 miles.
Therefore, the distance from village to railroad station is 30 miles.
The distance from the village to the railroad station is 30 miles
Speed is the ratio of distance to time taken. It is given by:
Speed = distance/time
Let d represent the distance from the village to the rail station.
When Going at a speed of 15mph, let us assume he spent a hour, hence:
15 = d/a
d = 15a
When coming at a speed of 10mph, let us assume he spent b hour, hence:
10 = d/b
d = 10b
Therefore:
15a = 10b
But it took 1 more hour for the bicyclist to get back to the village, hence b = a + 1, hence:
15a = 10(a + 1)
15a = 10a + 10
5a = 10
a = 2 hours
d = 15a = 15(2) = 30 miles
Therefore, the distance from the village to the railroad station is 30 miles

Stephanie is going to summer camp. There are three cabins to which she could be assigned: Pine Cabin, Maple Cabin, or Spruce Cabin. She can be assigned either a top bunk bed or bottom bunk bed.
Answer: The probability of Stephanie being on a top bunk is 50%
The probability of Stephanie being in Spruce Cabin is 3333.3%
The probability of Stephanie being in Pine cabin on bottom bunk is 80%
Step-by-step explanation:
The probability of Stephanie being assigned to the Pine Cabin and a bottom bunk bed is 1/6.
We have,
To find the probability of Stephanie being assigned to a specific cabin and a specific bunk, we need to know the total number of possible outcomes.
In this case, there are 6 possible outcomes because there are 3 cabins and 2 bunk bed options for each cabin:
Pine Cabin, top bunk
Pine Cabin, bottom bunk
Maple Cabin, top bunk
Maple Cabin, bottom bunk
Spruce Cabin, top bunk
Spruce Cabin, bottom bunk
Let's say we want to find the probability of Stephanie being assigned to the Pine Cabin and a bottom bunk bed.
There is only one outcome that satisfies this condition (Pine Cabin, bottom bunk),
So the probability is:
1 outcome / 6 possible outcomes = 1/6
Therefore, the probability of Stephanie being assigned to the Pine Cabin and a bottom bunk bed is 1/6.
We can similarly calculate the probability for any other combination of cabin and bunk bed by counting the number of outcomes that satisfy the condition and dividing by the total number of possible outcomes.
Thus,
The probability of Stephanie being assigned to the Pine Cabin and a bottom bunk bed is 1/6.
