Mensuration of flat shapesGiven Data
Radius = 3 3/4 ftLet us first convert to proper fraction
Radius = 15/4 ft
We know that the expression for the circumference of circle is given as
Circumference = 2πr
Substituting our given data for radius we have
Circumference = 2*3.142*15/4
Circumference = 94.26/4

if 300 people come to the gym on a given day, approximately how many people would you expect to exercise for more than 136 minutes?
===========================================================
Explanation:
Add up the numbers in the second column:
4+19+25+32 = 80
There are 80 people being surveyed in the table.
Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.
The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5
----------
Multiply this probability with the larger sample size of 300 to get
(2/5)*300 = 0.4*300 = 120
We estimate that 120 people would exercise for more than 136 minutes.
Note that 120/300 = 2/5.

what is the best reasoning for line 3
Answer:
E
Step-by-step explanation:
"S" stands for "side" and "A" stands for "angle"
SAS = side angle side
The order is important because the angles must be between the two congruent sides.
One pair of congruent sides is AC = CE as shown by the single tickmarks.
The other pair of congruent sides is BC = CD shown by the double tickmarks
The congruent angles are the vertical angles BCA and DCE. Vertical angles are always congruent. Note how these angles are sandwiched between the tickmarked sides.

A student scored in the 85th percentile on her chemistry exam. What does this student's score mean in relation to those of the other test takers? (4 points) Group of answer choices Her score was better than those of 85% of all test takers. Her score was worse than those of 85% of all test takers. Her score on the exam was 85%. Her score was in the top 85% of all test takers' scores.
Answer:
The answer is
her score was in the top 85% of all test takers' scores.
Step-by-step explanation:
Percentile is the relative standing in a set of data from the lowest values to highest values.
If your score is in the 85th percentile, it means that 85% of the scores are below your score and 15% are above your score.
Answer:
A. Her score was better than those of 85% of all test takers.
Step-by-step explanation:
This means that 85% of the students scored lower on the test, so approximately 15% scored higher.

12-inch-tall boxes are being stacked next to 8-inch-tall boxes.
What is the shortest height at which these two stacks will be the same height?
Answer:
First, we have to find the LCM of 12 and 8 which would be 24. Since we have to multiply 8 by 3, and 12 by 2, then the shortest height would be two 12-inch boxes, and three 8-inch boxes.

An angle measures 64.8° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
77.4 degrees and 12.6 degrees
Step-by-step explanation:
Let the angles be x and x - 64.8.
Therefore, on the basis of knowledge that complementary angles add up to 90 degrees :
x + x - 64.8 = 90
2x = 154.8
x = 77.4 degrees
x - 64.8 = 77.4 - 64.8 = 12.6 degrees

sobre un estante se pueden colocar 30 libros de ciencias y 6 lubros de letras o 18 libros de letras y 10 libros de ciencias ¿cuantos libros de letras unicamente se pueden colocar?
Usando un sistema de ecuaciones vamos a ver que entran 24 libros de letras en el estante.
Cuantos libros de letras se pueden colocar?
Vamos a usar las variables:
x = peso de un libro de ciencias.y = peso de un libro de letras.Por el texto, podemos saber que el peso maximo que tolera el estante esta dado por el sistema de ecuaciones.
30*x + 6*y = P
10*x + 18*y = P
Podemos igualar esas dos ecuaciones para obtener:
30x + 6y = 10x + 18y
30x - 10x = 18y - 6y
20x = 12y
x = (12/20)*y
Ahora, podemos reemplazar esto en una de las dos ecuaciones, por ejemplo la primera:
30x + 6y = P
30*(12/20)y + 6y = P
(3/2)*12*y + 6y = P
18y + 6y = P
24y = P
Así concluimos que entran 24 libros de letras en el estante.

What is the decimal equivalent to -3 3/12
[tex]\huge\rm{ANSWER:}[/tex]
[tex]\huge \rm{ - 3.25}[/tex][tex]\huge\rm{SOLUTION:}[/tex]
To begin, keep in mind that - 3 3/12 is a mixed number, also known as a mixed fraction. It has a valid fraction as well as a complete number.
The following is a list of the numbers in a mixed fraction:
[tex]\huge \rm{ - 3}[/tex] the whole number.
[tex]\huge \rm{ 3}[/tex] the numerator
[tex]\huge \rm{ 12}[/tex] the denominator
Follow these procedures to convert -3 3/12 from a mixed number to a decimal number:
Divide the denominator by the numerator to convert the correct fraction to decimal.
3 ÷ 12 = 0.25
To get the entire number of the mixed fraction, multiply it by this decimal number.
-3 + 0.25 = - 3.25
Therefore, the decimal equivalent to -3 3/12 is -3.25
