there are 126 students.
2/9 of them are taking geometry. 3/7
of the students taking
geometry are male.
how many female students are taking geometry?
Out of 126, 2/9 of them are taking geometry , 3/7 of the students are males ,number of female students taking geometry are 16.
As given in the question,
Total number of students = 126
Number of Students taking geometry = (2/9) × 126
= 28
Number of male students taking geometry= (3/7) × 28
= 12
Number of female students taking geometry= 28 - 12
= 16
Therefore, out of 126, 2/9 are taking geometry , 3/7 are males ,number of female students taking geometry are 16.

MAPS Leila is walking from the park at point P to a restaurant at point R. She wants to stop for a break when the distance she has traveled and the distance she has left to travel has a ratio of 3:5. At which point should Leila stop for her break?
The point at which Leila should stop to take break is (6.25 , 3.75)
Given P(10 , 3) and R (0 , 4)
The ratio is 3:5
Let the break point be point B.
The formula is : (n(x₁) ₊ m(x₂)/ m₊n , n(y₁) ₊ m(y₂)/ m₊n)
P(10,3) = (x₁ , y₁)
R(0,4) = (x₂ , y₂)
m:n = 3:5
B = (5(10) ₊ 3(0)/3₊5 , 5(3) ₊ 3(4)/3₊5)
B = (50₊0/8 , 15₊12/8)
B = (50/8 , 27/8)
B = (6.25 , 3.75)
Hence Leila should stop at point (6.25 , 3.75) for her break.

Anna took a taxi from her house to the airport. the taxi company charged a pick-up fee of $3 plus $2.25 per mile. the total fare was $48, not including the tip. how many miles was the taxi ride?
Answer:
20
Step-by-step explanation:
The total fare, f, is:
f = 2.25x + 3
We want to solve for x. the number of miles. This is fairly simple if we know f.
48 = 2.25x + 3
48 - 3 = 2.25x + 3 - 3
45 = 2.25x
45/2.25 = 2.25x/2.25

a fishing boat accidentally spills 15 barrels of diesel oil into the ocean. each barrel contains 42 gallons. if the oil film on the ocean is 2.5×102nm thick, how many square meters will the oil slick cover?
The square meters of the area the oil slick will cover is 9.6 × 10⁶ m².
What is meant by volume?Volume is defined as the amount of three-dimensional space enclosed by a closed surface.
The liter (L) is the metric system's base volume unit, with several extended volume units also available. There are also many metric volume units based on the a cubic length dimension, including such cubic meters or cubic centimeters. Gallons and ounces are examples of imperial volume units.Now, as per the given question;
First, we determine the entire volume of oil in gallons by multiplying the volume per barrel even by total number of barrels:
15×42 gal = 630 gal
This volume must be converted to square meters:
V = 630 gal × (0.00379 m³/ gal
V = 2.4 m³
The thickness (height) of a oil film in meters is required:
h = 250 nm × (m/10⁻⁹nm)
h = 2.5 × 10⁻⁷m
The surface area of a oil film is calculated by dividing the oil volume by height of the oil film.
A = V/h
A = 2.4 m³/2.5 × 10⁻⁷m
A = 9.6 × 10⁶ m²
Therefore, the area of the oil slick cover is found to be 9.6 × 10⁶ m².

What is the MAD?
According to the given information the mean(MAD) of the data is = 16.
What is the mean mathematical term?The mean is the average of a set of variables in mathematics and statistics. The mean can be calculated in a variety of ways, such as the simple arithmetic mean (add the numbers and divide the sum by the number of observations), geometric mean, and harmonic mean.
According to the given data:(13 ,14 ,14, 16, 16, 16, 16, 18, 18, 19)
adding the numbers together.
(13 + 14 + 14 + 16 + 16 + 16 + 16 + 18 + 18 + 19)
= 160.
Then divide it by the amount of numbers. Which is ten.
160 divided by 10 = 16.
—MAD—
Subtract each value from the mean.
(|13-16| + |14-16| + |14-16| + |16-16| + |16-16| +|16-16| + |16-16| + |18-16| + |18-16| + |19-16|)
Negative numbers are unimportant; everything should be positive.
(3 + 2 + 2 + 0 + 0 + 0 + 0 + 2 + 2 + 3)
= 16.
16 divided by 16 (amount of numbers).
MAD = 1

The volume of the water filled in the cylinder A is 141.77 cm³.
How do you describe a cylinder?A cylinder is a 3 solid that contains two parallel bases connected at a fixed distance by a curved surface.
These bases are typically circular in shape (such as a circle), with the center of a two bases connected by a line segment known as the axis.A cylinder does have two flat ends shaped like circles. A curved face which resembles a tube connects these two faces. A flat net for just a cylinder resembles a rectangle with such a circle connected at each end.The formula for the volume of the cylinder is;
Volume = πr²h

A bee flies at 20 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 17 minutes, and then flies directly back to the hive at 12 feet per second. It is away from the hive for a total of 19
minutes.
In linear equation, the distance of the flowerbed from the hive is 2250 feet.
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.Let , the distance of the flowerbed from the hive is feet.
The bee flies 20 feet per second directly to a flowerbed from its hive and flies directly back to the hive at 12 feet per second.
time = distance / speed
So, the time taken by the bee to reach the flowerbed x/20 seconds and the time taken to fly back to the hive = x/12 seconds.
The bee stays at the flowerbed for 15 minutes or (15×60)seconds or 900 seconds and it is away from the hive for a total of 20 minutes or (20×60)seconds or 1200 seconds.
So, the equation will be
x/20 + x/12 + 900 = 1200
3x + 5x / 60 = 300
8x = 300 * 60
x = 2250
Thus, the distance of the flowerbed from the hive is 2250 feet.
