the radius of a circle is 5 inches what is the area of a sector biunded by 180 degrees arc
The area of a sector with a radius of 5 inches and a 180-degree arc is half the area of the full circle, resulting in 39.27 square inches when rounded.
Explanation:The area of a sector of a circle with radius 5 inches that is bounded by a 180-degree arc can be found by first calculating the area of the entire circle and then taking half of that area, since 180 degrees is half of the full 360 degrees of a circle. The formula to calculate the area of a circle is A = πr². For a radius (r) of 5 inches, the entire circle's area would be A = π(5 inches)².
Thus, the entire circle area is A = 3.1415927 × (5 inches)² = 78.53981633974483 square inches. Since the sector is half of the circle, the area of the sector would be 39.269908169872415 square inches, or when rounded to two decimal places, 39.27 square inches.
The head-to-tail length of a species of fish is normally distributed, with a
mean of 17.4 cm and a standard deviation of 3.2 cm. One fish is 16.3 cm
long. What is the score of the length of this fish? Round your answer to two
decimal places.
A. 0.54
B. 0.34
C. -0.34
D. -0.54
Answer:
C. -0.34
Step-by-step explanation:
We have that for a normal distribution, the value of z can be calculated using the following formula:
z = (x - m) / sd
where x is the value to evaluate, m the mean and sd the standard deviation, we have those values x = 16.3, m = 17.4 and sd = 3.2
if we replace we have:
z = (16.3 - 17.4) /3.2
z = -0.3437
if we round to 2 decimal places, it would be -0.34, that is, the answer is C.
The z-score for a fish measuring 16.3 cm, with a mean length of 17.4 cm and a standard deviation of 3.2 cm, is -0.34.
The score of the length of the fish, also known as the z-score, is calculated by subtracting the mean from the observed value and then dividing by the standard deviation. Using the provided data, we have a mean (μ) of 17.4 cm and a standard deviation (σ) of 3.2 cm. The fish in question measures 16.3 cm.
To find the z-score, the calculation is as follows:
Z = (X - μ) / σ
Z = (16.3 cm - 17.4 cm) / 3.2 cm
Z = -1.1 cm / 3.2 cm
Z = -0.34 (rounded to two decimal places)
Therefore, the z-score for a fish that is 16.3 cm long is -0.34, which corresponds with answer option C.

the lines on a coordinate plane are perpendicular.
perpendicular lines form what type of angles?
Final answer:
Perpendicular lines on a coordinate plane intersect to form right angles, which are precisely 90°. The slopes of perpendicular lines are negative reciprocals of each other.
Explanation:
When two lines on a coordinate plane are described as being perpendicular, this means they intersect to form right angles, which are angles of 90°. It's important to recognize that perpendicular lines have slopes that are negative reciprocals of each other. For example, if one line has a slope of 2, a line perpendicular to it would have a slope of -1/2. These slopes ensure that the angles formed between the lines are exactly 90 degrees.
In geometry and physics, this concept is further explored with orthogonal vectors, which are two vectors with directions that differ by exactly 90°, synonymous with perpendicular vectors. Their importance lies in various applications, such as breaking down a force into components acting along perpendicular axes.

two similar trapezoids have areas of 180 cm2 and 45cm2. what is their ratio of similarity
The ratio of similarity between the two trapezoids is 2:1, which means that the linear dimensions of the larger trapezoid are twice those of the smaller one.
To find the ratio of similarity between two similar trapezoids with areas of 180 [tex]cm^2[/tex] and 45 [tex]cm^2[/tex], we use the principle that the ratio of the areas of similar figures is equal to the square of the ratio of their corresponding linear dimensions. In other words, if the ratio of similarity (scale factor) between the linear dimensions of two similar figures is 'k', then the ratio of their areas is '[tex]k^2[/tex]'.
Let the ratio of similarity be 'k'. Then we have 180/45 = k^2. Simplifying this, we get 4 = [tex]k^2[/tex] and thus, k = 2. This means the linear dimensions of the larger trapezoid are twice those of the smaller one.
Therefore, the ratio of similarity between the two trapezoids is 2:1.

Danielle had planned her gift basket to be priced at $50 with a 40% gross margin. She forgot packaging costs which will be $3 per unit. If she still keeps the price at $50, how much will her gross margin percentage be after packaging costs?
a) 30%
b) 34%
c) 43%
d) 47%
The gross margin percentage after packaging costs would be a) 30%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Danielle had planned her gift basket to be priced at $50 with a 40% gross margin.
let, The original price be 'x'.
Therefore, $50 is 140% of 'x' which is,
(140/100)×x = 50.
1.4x = 50.
x = 50/1.4.
x = 35.71.
Now, The packaging cost is $3 which makes the cost of the product 38.71.
So, (50/38.71)×100.
= 29% gross margin.

On a certain hot summer's day, 744 people used the public swimming pool. The daily prices are $ 1.75 for children and $ 2.00 for adults. The receipts for admission totaled $ 1392.25 .How many children and how many adults swam at the public pool that day?
Answer:
383 children and 361 adults
Step-by-step explanation:
Let's say there are a adults and c children. Since the total number of people was 744, we can write:
a + c = 744
We also know that children's prices are $1.75 per child and adults' prices are $2 per adult. Since the total is $1392.25, we can write:
1.75c + 2a = 1392.25
Now we have a system of linear equations:
a + c = 744
1.75c + 2a = 1392.25
Multiply the first equation by 2:
2 * (a + c = 744) ⇒ 2a + 2c = 1488
Now subtract the second equation from this one:
2a + 2c = 1488
- 2a + 1.75c = 1392.25
___________________
0a + 0.25c = 95.75
c = 383
Plug this in to find a:
a + c = 744
a + 383 = 744
a = 361
There were 383 children and 361 adults.
Lets use some variables:
x = number of adults
y = number of children
744 total people used the public swimming pool and the number adults and children are unknown, so, we can write an equation like:
x + y = 744
Since $2 are for adults, we can write that as 2x. Since $1.75 are for children, we can write that as 1.75y. Since the total price is $1,392.25, that's what the equation should equal. Equation:
2x + 1.75y = 1,392.25
Now, we have a system of equations.
~Rationalize equations
x + y = 744, 2x + 7/4y = 5569/4
~Isolate x for [ x + y = 744 ]
x + y - y = 744 - y
x = 744 - y
~Substitute with x
2(744 - y) + 7/4y = 5569/4
~Isolate y for [ 2(744 - y) + 7/4y = 5569/4 ]
2(744 - y) * 4 + 7/4y * 4 = 5569/4 * 4
8(744 - y) + 7y = 5569
5952 - 8y + 7y = 5569
5952 - y = 5569
5952 - 5952 - y = 5569 - 5952
-y = -383
-y/-1 = -383/-1
y = 383
~Substitute y with 383 in [ x = 744 - y ]
x = 744 - 383
x = 361
Therefore, there are 361 adults and 383 children.
Best of Luck!

Show how to find the inverse of f(x) = x^3 - 5. Calculate 3 points on f(x) and use these points to show that the inverse is correct.
Answer:
[tex]f^{-1}(x) = \sqrt[3]{x+5}[/tex]
Step-by-step explanation:
A function [tex]f^{-1}[/tex] is the inverse of f if whenever y =f(x) and [tex]x =f^{-1}[/tex]
To find the inverse of f(x) = [tex]x^{3}[/tex] - 5, we use the following steps:
Step 1 : Put y for f(x) and solve for xy = [tex]x^{3}[/tex] - 5
<=> [tex]x^{3}[/tex] = y + 5
<=> x = [tex]\sqrt[3]{y+ 5}[/tex]
Step 2: Put [tex]f^{-1}(y)[/tex] for x, we have:[tex]f^{-1}(y) =\sqrt[3]{y+5}[/tex]
Step 3: Interchange y =x, we have[tex]f^{-1}(x) = \sqrt[3]{x+5}[/tex]
Let Calculate 3 points on f(x)
x = 0 => y = -5
x = 1 => y = -4
x = 2 => y = 3
Let Calculate 3 points on [tex]f^{-1}[/tex] (x)
x = -5 => y = 0
x = -4 => y = 1
x = 3 => y = 2

A photo is printed on a 20-inch by 24-inch piece of paper. The photo covers 320 square inches and has a ubiform border. What is the width of
the border?
Answer:2 in.
Step-by-step explanation:
Given
Dimension of photo frame is [tex]20\ in.\times 24\ in.[/tex]
If the photo cover an area of [tex]320\ in.^2[/tex]
Suppose x be the width of border
Therefore dimension of frame without border is
[tex]A'=(20-2x)(24-2x)[/tex]
And [tex]A'[/tex] must be equal to [tex]320\ in.^2[/tex]
So,
[tex]\Rightarrow (20-2x)(24-2x)=320[/tex]
[tex]\Rightarrow (10-x)(12-x)=80[/tex]
[tex]\Rightarrow 120-10x-12x+x^2=80[/tex]
[tex]\Rightarrow x^2-22x+40=0[/tex]
[tex]\Rightarrow x^2-20x-2x+40=0[/tex]
[tex]\Rightarrow (x-2)(x-20)=0[/tex]
Thus there are two values of x out of which [tex]x=20\ in.[/tex] is not valid because it is not feasible
thus width of border is [tex]x=2\ in.[/tex]
