Answers
Answer/Step-by-step explanation:
a. Volume of hemisphere = ½(⁴/3πr³)
r = 30 cm
Volume = ½(⁴/3 × π × 30³)
Volume = ⅔ × π × 27,000 = 56,548.6677 ≈ 56,549 cm³
b. 4,500 cm³ = 1 min
56,549 cm³ = (56,549 × 1)/4,500
= 12.5664444 ≈ 12.6 mins

Imagine you are playing golf, and you’ve just set up the golf ball on the tee. You test your grip, take a few practice swings, and peer into the distance at the flag pole marking the first hole for the course. Your wise golf ball guru (who happens to also teach physics) tells you to “Be the ball, young grasshopper.” So you close your eyes and picture the distance the ball must travel. “Yes, young earthworm”, your sensei says, “that distance you see is the displacement you must achieve, displacement is the change in position from one place to another.”

Step-by-step explanation:
Solving ...
M = (A +B)/2

There is a spinner with 10 equal areas, numbered 1 through 10. If the spinner is spun
one time, what is the probability that the result is a multiple of 5 or a multiple of 2?
Answers
Answer:
3/5
Step-by-step explanation:
In the numbers 1 thru 10, there are 5 multiples of 2 (2, 4, 6, 8, 10) and 2 multiples of 5 (5, 10). Since you cannot count 10 twice, there are 6 possibilities (2, 4, 5, 6, 8, 10)
So the probability of spinning a multiple of 2 or 5 is 6/10 = 3/5
Answer:2/10 probabilty for the multiple of 5 and a 5/10 or 50% chance that it will be a multiple of 2
Step-by-step explanation: 10 areas, there are 2 multiples of 5,( 5 and 10 )and there is a 2/10 chance of landing on landing 5 or 10 because there are 2 multiples of 5. There are also 5 multiples of 2, (2, 4, 6, 8, 10) 5/10 chance because there are 5 multiples out of 2

If you roll two six-sided dice, what is the probability that at least one dies shows a 5 ?
Answers
Answer:
[tex]\frac{11}{36} = 0.3056[/tex] probability that at least one dies shows a 5.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Each dice:
6 sides, one of which is 5.
So 6-1/6 = 5/6 probability of rolling a 5.
Probability of not rolling a five in two rolls:
(5/6)^2 = 25/36
Probability of rolling a five in at least one of the rolls:
[tex]p = 1 - \frac{25}{36} = \frac{36}{36} - \frac{25}{36} = \frac{11}{36} = 0.3056[/tex]
[tex]\frac{11}{36} = 0.3056[/tex] probability that at least one dies shows a 5.

Which expression is equivalently to x^2 + 2x + 2?
Answers
Answer:
(X-1+I)(x-1-I)
Step-by-step explanation:
Expression (x + 1 - i)(x + 1 + i) is equivalent to x² + 2x +2.
Option (B) is correct option.
What is an algebraic expression?Variables, integers, and a variety of mathematical procedures make up an algebraic expression.
To find the expression equivalent to x² + 2x +2,
Solve with the help of options.
(A)
(x - 1 + i)(x - 1 - i)
Solve by using formula (a + b)(a - b) = a² - b²
(x - 1 + i)(x - 1 - i) = (x -1)² - i² = x² + 1 - 2x +1 = x² - 2x + 2
(B)
(x + 1 - i)(x + 1 - i)
Solve by using formula (a + b)(a - b) = a² - b²
(x + 1 - i)(x + 1 + i) = (x + 1)² - i² = x² + 1 + 2x +1 = x² + 2x + 2
Expression in option (B) is equivalent to x² + 2x + 2.

The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the Sector formula: Area of Segment = θ − sin(θ) 2 × r2 (when θ is in radians) Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)

Put the equation 169x^2+25y^2-4225=0 in standard form and sketch the ellipse including the foci in your sketch
Answers
Answer:
The standard form of the ellipse is [tex]\frac{x^{2}}{25} +\frac{y^{2}}{169} = 1[/tex]. Coordinates of the foci are [tex]F_{1} (x,y) = (0,-c)[/tex] and [tex]F_{2}(x,y) = (0,c)[/tex], respectively.
Step-by-step explanation:
The equation of a ellipse centered in the origin in standard form is defined by following formula:
[tex]\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}} = 1[/tex] (1)
Where [tex]a, b[/tex] are the coefficients of the ellipse.
Now we proceed to transform the equation of the ellipse in general form into standard form by algebraic means:
[tex]169\cdot x^{2}+25\cdot y^{2}-4225 = 0[/tex]
[tex]169\cdot x^{2}+25\cdot y^{2} = 4225[/tex]
[tex]\frac{x^{2}}{25} +\frac{y^{2}}{169} = 1[/tex]
Since [tex]b > a[/tex], then major axis of the ellipse is located in y-axis. The distance between center and focus ([tex]c[/tex]) is calculated by following Pythagorean identity:
[tex]c =\sqrt{b^{2}-a^{2}}[/tex] (2)
[tex]c = 12[/tex]
The location of the foci are represented by [tex]F_{1} (x,y) = (0,-c)[/tex] and [tex]F_{2}(x,y) = (0,c)[/tex]. If we know that [tex]c = 12[/tex], then the location of the foci are, respectively:
[tex]F_{1}(x,y) = (0,-12)[/tex], [tex]F_{2}(x,y) = (0,12)[/tex]

A store buys a jackets for $20.00 and sells it for 80% more than that what is the selling price of the jacket
Answers
Answer:
$36
Step-by-step explanation:
in the beginning $20 is %100 so divide 20 by 100 .you'll get .2 but to make this simple you'll want %10 so multiply .2 times 10 and you get 2 .now that 2 is %10 and you want %80 you multiply 2 8 times (or add it 8 times) because %10 times 8 = %80 so 2 times 8 = 16 .now that you have the %80 you want to add it to the %100 because they sold it for %80 then the price they bought if for (you get %180) . then you add the $20 to the $16 because that is what each percent equals (you get $36)
Answer:
$36
Step-by-step explanation:
What we know: The jacket is marked up by 80% of the jacket. The store is now selling the jacket for 180% of what they bought it for.
Set up problem: x 180%
___ = ____
$20 100%
What do the numbers mean when set up like this(referring to problem set up): We know that $20 is the original price of the jacket. So $20 is 100% of the jacket(if that makes sense). Markup is 80% because "sells it for 80% more" . So it goes on top.
Solving the Problem#1: 180 x 20 = 3600
Solving the Problem#2: 3600/1000= $36
Checking My Math: What is 80% of $20. Let's divide $20 into 4 parts.
$4 + $4 + $4 + $4 + $4 =20
$4 is 20% of 20
$8 is 40% of 20
$12 is 60% of 20
$16 is 80% of 20
$20 is 100% of 20
Final Answer: $36 is the selling price of the jacket
Note: I used a scientific calculator for some calculations.
