The ratio of the lengths of the three sides of a triangle is 6:8:9. Its perimeter is 345 in. Find
the measure of the SMALLEST side of the triangle.
Do not include unit in your answer. Type the numerical answer ONLY.
Answer:
40 : 60 : 90
Step-by-step explanation:
To solve this add the total of all the numbers of the ratio. 4 + 6 + 9 = 19.
Take that total and divide the perimeter by it: 190 / 19 = 10.
So each of those ratios need to be multiplied by 10.
Final answers: 40 : 60 : 90. They have a ratio of 4:6:9 and add up to 190.

Answer:
What is the area of the border of the wall?
Step-by-step explanation:
Let us denote by P the set of all people, by S the set of people who are single, by C the set of people who have children, by W the set of women and by M the set of men. For each question below, write down an expression that represents the set being described. Write exactly one expression for each question.
a. Women who are either married with children, or single and do not have children.
b. All possible married heterosexual couples, i.e., all possible pairings of married men and married women.
c. The number of all possible married heterosexual couples.
Solution :
Given :
The events are as follows :
P : Set of all the people
S : Set of people those who are single
C : Set of people having children
W : Set of women
M : Set of men
a). Now set of married women having children is given by :
[tex]$\left( (P-S)-M \right) \cap C $[/tex]
And set of single women who do not have any children : (S -C) - M
Thus the set of women those who are either married and have children or they are single and they do not have any children is represented by :
[tex]$\left( (S-C)-M\right) \cup \left( ((P-S)-M) \cap C \right) $[/tex]
b). Set of Married men : [tex]$\left( (P-S) \cap M$[/tex]
Set of Married men : [tex]$\left( (P-S) \cap W$[/tex]
Set of all possible married who are heterosexual couples, that is, all possible pairings of the married men and the married women is represented by :
[tex]$((P-S) \cap M) \cap ((P-S) \cap W )$[/tex]
c). The number of all the possible married heterosexual couples will be represented by the cardinality of the above set, which represents the number of the elements in the set.
Thus the number of the married heterosexual couples is given by :
[tex]$n[((P-S) \cap M) \cap ((P-S) \cap W)]$[/tex]

The equation gives the position s = f(t) of a body moving
on a coordinate line (s in meters, t in seconds).
1) s = 1 + 9(cos t)
Find the body's speed at time t=pi/3 sec.
2) s = 12(sin t) - (cos t)
Find the body's velocity at time t=pi/4 sec.
Answer:
1) The velocity at this time is of [tex]-9\frac{\sqrt{3}}{2}[/tex] meters per second.
2) The velocity at this time is of [tex]13\frac{\sqrt{2}}{2}[/tex] meters per second.
Step-by-step explanation:
This question involves concepts of derivatives.
The velocity is the derivative of the position.
We use these following derivatives:
[tex](\sin{x})^{\prime} = \cos{x}[/tex]
[tex](\cos{x})^{\prime} = -\sin{x}[/tex]
1) s = 1 + 9(cos t)
Find the body's speed at time t=pi/3 sec.
We have to find the derivative at [tex]t = \frac{\pi}{3}[/tex]. So
[tex]v = (1 + 9\cos{t})^{\prime} = -9\sin{t}[/tex]
[tex]v(\frac{\pi}{3}) = -9\sin{\frac{\pi}{3}}[/tex]
[tex]\frac{\pi}{3}[/tex] is a common angle, which has a sine of [tex]\frac{\sqrt{3}}{2}[/tex]. So
[tex]-9\sin{\frac{\pi}{3}} = -9\frac{\sqrt{3}}{2}[/tex]
The velocity at this time is of [tex]-9\frac{\sqrt{3}}{2}[/tex] meters per second.
2) s = 12(sin t) - (cos t)
Find the body's velocity at time t=pi/4 sec.
We have to find the derivative at [tex]t = \frac{\pi}{4}[/tex]. So
[tex]v = (12\sin{t} - \cos{t})^{\prime} = 12\cos{t} + \sin{t}[/tex]
[tex]\frac{\pi}{4}[/tex] is a common angle, which has both sine and cosine of [tex]\frac{\sqrt{2}}{2}[/tex]. So
[tex]12\cos{\frac{\pi}{4}} + \sin{\frac{\pi}{4}} = 12\frac{\sqrt{2}}{2} + \frac{\sqrt{2}}{2} = 13\frac{\sqrt{2}}{2}[/tex]
The velocity at this time is of [tex]13\frac{\sqrt{2}}{2}[/tex] meters per second.
April is making necklaces using beads
that are 6 millimeters in diameter.
What is the diameter of each bead in
centimeters?
Step-by-step explanation:
To convert millimeters to centimeters we divide
As, 10 millimeters = 1 centimeter
So 1 centimeter = 1/10 millimeter
So here of we have 6 millimeters, so centimeters = 6/10 = 0.6cm
So the diameter of each bead in the necklace = 0.6cm
The diameter of bead in a necklaces is 0.6 centimeters.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
Given that, April is making necklaces using beads that are 6 millimeters in diameter.
We know that, both millimeters and centimeters is the unit to measure the length. One millimeter is equal to 0.1 centimeters and 1 cm is equal to 10 mm.
Here, 6 millimeters
= 6×0.1
= 0.6 centimeters
Therefore, the diameter of a bead is 0.6 centimeters.

Martin has two rectangles that are the same size. One
rectangle is cut into 2-size parts. The other rectangle is cu
-size parts. He wants to cut the rectangles so they have
same size parts. How can he cut each rectangle?
A common denominator is a common multiple of the
denominators of two or more fractions. Fractions with
common denominators represent wholes cut into the
same number of parts.
