Answer:
Lin = 48 seconds
Diego = 30 seconds
Step-by-step explanation:
Hi, to answer this question we have to divide the total ounces of drink by the amount that each one drank per second, for each case.
Mathematically speaking:
Lin = 12 ounces / (1/4) ounces/second = 12/ (1/4) = 48 seconds
Diego = 20 ounces / (2/3) ounces/second = 20/ (2/3) = 30 seconds
Feel free to ask for more if needed or if you did not understand something.
Lin = 48 seconds
Diego = 30 seconds
The calculation is as follows:Lin = 12 ounces ÷ (1/4) ounces/second = 12 ÷ (1/4) = 48 seconds
Diego = 20 ounces ÷ (2/3) ounces/second = 20 ÷ (2/3) = 30 seconds

What is the area of the following circle? Either enter an exact answer in terms of pie or use 3.14 for pie and enter your answer a decimal
The area of a circle with a radius of 1.2 meters is 4.5 m², rounded to two significant figures to match the precision of the given radius.
Explanation:The area of a circle is given by the formula A = πr², where π (pi) represents a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. When calculating the area with a radius of 1.2 meters, we get the precise calculation as A = π(1.2 m)² = 4.5238934 m². However, as the radius is given with only two significant figures, the area should also be rounded to two significant figures, resulting in A=4.5 m².

in circle F, points A,B,C,D, and E are located on the circle such that measure of C=119°, and BE is perpendicular AD. determine the measure of arc AE. show how you arrived at your answer.
Answer:
Measure of arc AE = 58°
Step-by-step explanation:
As shown: ABCD is a quadrilateral, ∠C = 119°
So, ∠C + ∠A = 180°
∴ ∠A = 180° - ∠C = 180° - 119° = 61°
ΔAGB is a right triangle at G
So, ∠A + ∠B = 90°
∴ ∠ABG = 90 - ∠A = 90 - 61 = 29°
Arc AE opposite to the angle ∠ABG
So, measure of arc AE = 2∠ABG = 2 * 29° = 58°
A planet follows an elliptical path described by 256 x squared plus 16 y squared equals 4096.256x2+16y2=4096. A comet follows the parabolic path y equals x squared minus 16.y=x2−16. Where might the comet intersect the orbiting planet?
Final answer:
To find the intersection points of the comet and the planet's orbits, we need to solve the system of equations formed by their respective path equations.
Explanation:
To find where the comet might intersect the orbiting planet, we need to find the common points between the equation of the planet's elliptical path and the equation of the comet's parabolic path.
By substituting the expression for y in the equation of the planet into the equation of the comet, we get 256x^2 + 16(x^2 - 16) = 4096.
Simplifying this equation and solving for x will give us the x-coordinates where the comet may intersect the planet's orbit. Substituting these x-values back into either the planet's or comet's equation will give us the corresponding y-coordinates.
What is the area of this composite figure?
12.56 in. sq
10.28 in. sq
7.14 in. sq
16.56 in. sq
Answer:
7.14 in. sq
Step-by-step explanation:
First find the area of the square; 2x2=4
Now find the area of the semi-circle; radius = 1.
1 squared= 1 Now multiply by 3.14 which equals 3.14
Now divide by 2 because it's a semi-circle, you get 1.57.
Multiply 1.57 by 2 because you have 2 semi-circles, the would equal 3.14
Add 4+3.14 and you get 7.14
The area of the composite figure is 7.14 in. sq

y = b lines have a slope of 0Parallel Lines - Lines that have the same slope but different y-intercepts. They never intersect.Step-by-step explanation:
We are given the line y = 6, a horizontal line with a slope of 0.
According to the answer choices, we need to find an equation of a line that also has a slope of 0.
A, B, and D are all incorrect, as they have a different slopes than the original line (Slope of -6, undefined, and 6 respectively).
Therefore, our only option is C, which is the correct answer.
y = 1 has the same slope, a slope of 0. However, it has a different y-intercept, a y-intercept of 1 compared to the original y-intercept 6. They are parallel and will never intersect.

Percy and Caren are having a debate. Percy contends that the headquarters of the United States Department of Defense (also known as the Pentagon) has a longer perimeter than the United States Capitol. Caren contends the opposite. To settle their debate, they find satellite images of both buildings online and juxtapose them on a single coordinate grid (shown below). Assume the Pentagon is a regular pentagon with side length 300. The perimeter of the Pentagon is
Answer:
1500 units.
Step-by-step explanation:
-A pentagon is a a regular pentagon with 5 equal sides.
-Since the side length's are equal, the perimeter is simply the product of one side length by the number of sides of the polygon.
-Given its sides measures 300 each, its perimeter can be calculated as:
[tex]P=5s\\\\=5\times 300\\\\=1500 \ units[/tex]
Hence, the Pentagon's permimeter is 1500 units.
Answer:
The perimeter of the Pentagon is 1500
The perimeter of the Capitol is 1131
Percy would win the debate

an arc subtends a central angle measuring 2pi/3 radians. what fraction of the circumference is this arc?
Answer:
1/3
Step-by-step explanation:
The fraction of the circumference that the arc subtends is 1/3.
Explanation:An arc that subtends a central angle measuring 2π/3 radians is a fraction of the circumference. To find the fraction, we can use the formula:
Fraction of circumference = (angle/2π) x 1
Substituting the given angle into the formula, we have:
Fraction of circumference = (2π/3 /2π) x 1
Simplifying the expression, we get:

what's the answer to this ?
Answer:
x = 13.1°
A is correct answer
Step-by-step explanation:
Given Data:
Angle = ∅ = 24°
Base = b = 12
To find out:
Hypotenuses = x = ?
Formula:
Cos∅ = Base/Hypotenuses
Cos∅ = b/x
x = b/Cos∅
Solution:
x = b/Cos∅
x = 12/Cos(24°)
x = 12/0.91
x = 13.1°
What is the median for the given set of data?
{40, 54, 22, 30, 55, 13, 33}
A) 32
B) 33
C) 40
D) 42
Step-by-step explanation:
Arranging in ascending order, we get
13 , 22 , 30 , 33 , 40 , 54 , 55
no of data (N) = 7
Now Position of Median
= {(N +1 ) / 2}th item
= {(7+1) / 2 } that item
= 4 that item
So now exact median = 33
Answer:
The answer is 33
Step-by-step explanation:
By arranging the numbers in order of smallest to largest you get: ----------------> 13, 22, 30, 33, 40, 54, 55. Cross off a number from each side until you get one or two left in the middle. Cross out 13 and 55 then 22 and 54 then 30 and 40. Now you have 33 left in the middle, that is your median

Answer:
$1.67
Step-by-step explanation:
Let x be the no. of gums
96.6 + 0.79x》100
0.79x 》 3.4
x》4.3037974684
So x = 5
15% discount: she pays 0.85(96.6)
= 82.11
20% discount (after gums)
She pays 0.8[96.6 + 5(0.79)]
= 0.8(100.55)
= 80.44
Less:
82.11 - 80.44
= 1.67
1. The monthly rents for studio apartments in a certain city have a mean of $920 and a standard deviation of $190. Random samples of size 25 are drawn from the population and the mean of each sample is determined.
What is the mean of the indicated sampling distribution of sample means?
2. What is the standard error of the indicated sampling distribution of sample means?
3. Which one is more likely to take place?
a. Find one studio apartment that has a rent between $901 and $939.
b .Find a sample of 25 studio apartments with a mean rent between $901 and $939.
Answer:
1)Mean=920 $
2)Standard Error =S.E.=38
3)more likely to take place Event 25 studio apartments with a mean rent between $901 and $939
Step-by-step explanation:
Given:
True mean =920 $
S.D=190 $
No .of samples=25
To Find:
1)Mean of sample.
2)S.E
Solution:
Now , the mean for given sample distribution is given as 920 $
Hence Mean =920 $
Now calculating the Standard error
S.E.= S.D./Sqrt(n)
=190/Sqrt(25)
=190/5
=38
Therefore the Standard error is about 38 .
a) When n=1 then P(901≤X≤939)
So,
Z1=(901 -920)/190/Sqrt(1)]
Z1=-0.1
Z2=(939-920)/(190/Sqrt(1)]
Z2=0.1
So
Pr(-0.1≤Z≤0.1)=P(Z≤0.1)-P(Z≤-0.1)
=0.5398-0.4602
=0.0797 % chance of the sample distribution
b)n=25 then P(901≤X≤939)
Z1=(901-920)/S.E
Z1=-19/38=
Z1=-0.5
And Z2=0.5
So,
Pr(-0.5≤Z≤0.5)
=Pr(Z≤0.5)-Pr(Z≤-0.5)
=0.6915-0.3085
=0.3829
i.e 38.29 % chance of the sample distribution
Hence More likely to take place will be a sample of 25 studio apartments with a mean rent between $901 and $939.
0.3829>0.0797.
Because the probability of causing above event is more than the option A.
