Answer:
1. 75/6 (improper fraction) = 12 3/6 (mixed number) = 12 1/2 (simplified)
2. 2/12 = 1/6 (simplified)
3. 12/72 = 1/6 (simplified)
Hope this helps :)
Answer:
[tex]\frac{5}{6} * 15 = 12\frac{1}{2}[/tex]
[tex]\frac{2}{3} * \frac{1}{4} = \frac{1}{6}[/tex]
[tex]\frac{4}{9} * \frac{3}{8} = \frac{1}{6}[/tex]
Step-by-step explanation:
[tex]\frac{5}{6} * 15 = \frac{5 * 15}{6} = \frac{75}{6}\\[/tex]
Reduce the fraction by diving both sides by the common factor.
[tex]\frac{75}{6} = \frac{75 / 3}{6/3} = \frac{25}{2}[/tex]
To convert the improper fraction to a mixed fraction, divide the numerator (25) by the denominator (2), put the whole part of the result in front and the remainder in place of the original numerator.
25 / 2 = 12 with remainder of 1
[tex]\frac{25}{2} = 12\frac{1}{2}[/tex]
[tex]\frac{2}{3} * \frac{1}{4} = \frac{2 * 1}{3 * 4} = \frac{2}{12} = \frac{2/2}{12/2} = \frac{1}{6}[/tex]
[tex]\frac{4}{9} * \frac{3}{8} = \frac{4 * 3}{9 * 8} = \frac{12}{72} = \frac{12 / 12}{72 / 12} = \frac{1}{6}[/tex]

What does it mean when a data set or distribution has more variability than another
Answer: Standard deviation
Step-by-step explanation: The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each score lies from the mean. The larger the standard deviation, the more variable the data set is.
49^((1)/(2))- 25^((3)/(2))
Answer: -118
Step-by-step explanation:
49^((1)/(2))- 25^((3)/(2))=
49^(1/2) -25^(3/2)=
7-25^((2+1)/2)=
7-25^((2/2)+(1/2))=
7-25^(1+1/2)=
7-25^(1) *25^(1/2)=
7-(25*5)=
7-125=-118
Use the data and create a formula for the function that approximates the ground roll for a fully loaded cessna 172 at an elevation of:_____
The formula for the function that approximates the ground roll for a fully Cessna 172 at an elevation of x is y = 585(1.00009)x .
What is angle of elevation ?
The angle from the horizontal upward to an item is referred to as the angle of elevation. The line of sight of an observer would be above the horizontal. The angle from the horizontal downward to an item is referred to as the "angle of depression." The line of sight of an observer would be below the horizontal.Let the formula for the exponential function that approximates the ground roll for a fully loaded Cessna 172 at an elevation of x be
y =A(B)x ....(1)
Here,
A = ground roll at x =0,
B = growth factor.
Since at x =0, , Ground roll is = A = 585 ft ....(2)
On putting A = 585 in equation (1), we get
y = 585(B)x ....(3)
Now, at elivation of x = 1000 ft ,
Ground roll y = 640 ft.
So, putting these values in equation (3), to get
640 = 585(B)1000
Reversing the sides to get
585(B)1000 = 640
Or B1000 = 640/585
Or B1000 = 1.09017094
Or B = (1.09017094)1/1000
Or B = 1.00009 .....(4)
On putting the value of B in equation (3), we get
y = 585(1.00009)x
Hence, the formula for the function that approximates the ground roll for a fully Cessna 172 at an elevation of x is y = 585(1.00009)x .

Answer:
5
Step-by-step explanation:
This uses the Pythagorean theorem ([tex]f^2 + g^{2} =h^2[/tex]). So you would take your values 3 and 4 and plug them into the equation. [tex]3^2+4^2=h^2[/tex]. This becomes [tex]9+16=h^2[/tex]. Simplify and this becomes [tex]25=h^2[/tex]. If you take the square root of both sides you will end with 5 = h. Therefore your answer is 5.
Answer:
H=5
Step-by-step explanation:
Since it's a right triangle, you can use the Pythagorean Theorem which is [tex]a^2 + b^2 = c^2[/tex] or in this case: [tex]f^2 + g^2 = h^2[/tex]
Substitute 3 in for f and 4 in for g: [tex]3^2 + 4^2 = h^2[/tex]
Add 9 and 16 together, it's 25 and then find the square root of 25 and the square root of h and the answer is 5
[tex]f^2 + g^2=h^2\\3^2 + 4^2 = h^2\\9 + 16 = h^2\\25 = h^2\\\sqrt25 = \sqrt h^2\\5 = h[/tex]

The area A of a rectangle with dimensions 4x and 5 is described with the inequality 100 ≤ A ≤ 1,000.
Select the compound inequality for the area written in terms of x.
OA. 100 ≤ 10+ 8x ≤ 1,000
OB. 100 ≤ 18x ≤ 1,000
O C. 100 ≤ 9x ≤ 1,000
OD 100 ≤ 20x ≤ 1,000
The compound inequality for the area written in terms of x is 100 ≤ 20x ≤ 1,000.
We know that, the area of rectangle is given by:
Area = Length × Breadth
Now, we will substitute the values of length as 4x and breadth as 5 in the formula:
= 4x × 5
= 20x
Now. we will substitute this value in the inequality 100 ≤ A ≤ 1,000 to get the compound inequality:
100 ≤ 20 x ≤ 1,000.
Therefore, the compound inequality for the area written in terms of x is 100 ≤ 20x ≤ 1,000.

The question has to do with linear equation
What is a linear equation?A linear equation is a mathematical expression in which the highest power of the unknown is 1.
How to find the equation for the maximum speed of the hippopotamusLet
x = speed of cheetah and h = speed of hippopotamusGiven that the maximum speed, in miles per hour, of a cheetah is 18 more than 3 times the maximum speed of the hippopotamus
Now, since the maximum speed of the hippopotamus is h, 3 times the maximum speed of the hippopotamus is 3h.
Since the cheetah is 18 more than 3 times the maximum speed of the hippopotamus, we have that
x = 3h + 18
Substituting x = 75 into the equation, we have
75 = 3h + 18
So, the equation could be used to find the maximum speed of a hippopotamus h is C. 75 = 3h + 18

The sum of 4 consecutive odd integers is -24. What are they?
Step-by-step explanation:
4 consecutive odd integers means we start with x, then have x+2, x+4 and then x+6.
and then we have
-24 = x + x+2 + x+4 + x+6 = 4x + 12
4x = -36
x = -9
x+2 = -7
x+4 = -5
x+6 = -3
so, in sequence from small to large these 4 numbers are
-9, -7, -5, -3
The water level in Colorado river is 2.55 m below average. a large rainfall caused The water level to rise 0.8 m. what is the water level after the rainfall?
The water level after the rainfall is 3.05m
How to calculate the measurement of the water level after the rainfall ?
The water level in colorado river is 2.55m below average
A larger rainfall happened and the water level rose by 0.8m
Therefore the water level after the rainfall can be calculated by adding the previous water level which is 2.55 by the new increase which is 0.8
= 2.55 + 0.8
= 3.05
Hence the water level after the rainfall is 3.05 m

What in mathematics is a linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."Multiply both sides of the equation by a
coefficient - 2(4x - 3y ) = 11 × 2
3 ( 10x + 2y ) = ( - 1 ) × 3
apply multiplicative distribution law

Natalie surveyed 800 of the students in her school about their favorite color. Students could choose between blue and red. 77% said their favorite color was red. How many students' favorite color was blue?
30 points
The total number of students whose favorite color was blue is 184 students.
Total number of students Natalie surveyed in her school = 800
Given the percentage of students who said their favorite color was red = 77%
Now to calculate 77% of the total students is
= 77% of 800
= 77/100 * 800
= 616
The number of students who said red was their favorite color was 616.
So, the number of students who stated that blue was their favorite color
= total students - red color favorite students
= 800 - 616

What is the probability?
Probability determines the chances that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability of picking a yellow highlighter and then a green highlighter = (number of yellow highlighters / total number of highlighters) x = (number of green highlighters / total number of highlighters)

find the area of the shaded region.
round to the nearest tenth.
The area of the shaded region is 294.4 square meters
How to find the area of the shaded region?The given parameters are represented on the figure
By this;
The area of the shaded region is the sum of the area of the major sector and the area of the triangle
The area of the major sector is
A1= ∅/360 * πr²
The area of the triangle is
A2 = 0.5r²sin(x)
So, the total area is
Total = ∅/360 * πr² + 0.5r²sin(x)
This gives
Total = (360 - 130)/360 * 3.14 * 11.1^2 + 0.5 * 11.1^2 * sin(130 deg)
Evaluate
Total = 294.4
