Write 3/15 3/7 3/21 3/8 3/11 in ascending order
Answer:
The sorted inputs in order from least to greatest is:
3/21 < 3/15 < 3/11 < 3/8 < 3/7
Step-by-step explanation:
Using the given inputs:
3/15 3/7 3/21 3/8 3/11
As the least common denominator (LCD) is: 9240
Rewriting as equivalent fractions with the LCD:
3/15 3/7 3/21 3/8 3/11
1848/9240 3960/9240 1320/9240 3465/9240 2520/9240
Sorting this table by the numerators of the equivalent fractions in order from least to greatest:
3/21 3/15 3/11 3/8 3/7
1320/9240 < 1848/9240 < 2520/9240 < 3465/9240 < 3960/9240
Therefore, the sorted inputs in order from least to greatest is:
3/21 < 3/15 < 3/11 < 3/8 < 3/7
In a classroom of 30 students, in which 18 are girls and 12 are boys, what is the probability that two boys are selected without replacement by the teacher?
Answer:
about 4 out of 10
Step-by-step explanation:
Probabilities are used to determine the chances of events
The probability that two boys are selected is 0.1517
The given parameters are:
Boys = 12
Girls = 18
Total = 30
Given that the selection is without replacement, the probability that two boys are selected is:
p = 12/30 * 11/29
So, we have:
p = 0.1517
Hence, the probability that two boys are selected is 0.1517

Find side BC for the triangle shown (round to the nearest tenth).
Answer: 2.6 (rounded answer)
Step-by-step explanation: To solve for the side BC we can find the tangent (TAN) of 41 degrees. Since the tangent of an angle is equal to the opposite side over adjacent, we can set up an equation that looks like this, assigning side BC to be x:
tan(41)= x/16
0.1606567=x/16 <---- Use calculator to find tan(41)
0.1606567(16)=x/16(16) <---- Multiply each side by 16

Which measurement is closest to the circumference of a circle with an area of 36 square feet?
A
12.0 feet
B
21.3 feet
С
103.2 feet
D
113.0 feet
The measurement of the circumference of a circle is 21.3 ft.
What is Circumference of Circle?The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.
Here, given area of circle = 36 ft²
Area of Circle = πr²
36 = 3.14 X r²
r² = 11.46
r = 3.38 ft.
Circumference of Circle = 2πr
= 2 X 3.14 X 3.38
= 21.25 ft. ≈ 21.3 feet
Thus, the measurement of the circumference of a circle is 21.3 ft.

What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:
Step 1: You must divide the numerator of the fraction by the denominator of the fraction.
Step 2: Now you must add the quotient obtained to the Whole number part.
So, you get:
3 + 1/4
=3 + 0.25
= 3.25
Then, the scale image that maps "Figure a" onto "Figure b" is:
1: 3.25
Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .
Therefore, you get that the result is:
x = 3 * 3.25
or, x = 9.75
Hence, The solution is : the value of x is x = 9.75.

what is the slope of the line containing the points (1,10) and (-3,10)
Answer:
0
Step-by-step explanation:
Slope is Rise over Run (y / x).
For 2 points, you would take the difference of y-coordinates and divide by the difference of x-coordinates.
(Y1 - Y2) / (X1 - X2)
Since both y-coordinates are the same (ten minus ten), your slope is zero (zero divided by anything is zero).
