The perimeter of a triangle is 32 feet. One side of the triangle is 3 times the second side. The third side is 12 feet longer
than the second side. Find the length of each side.
We have a triangle whose perimeter is 32 feet. Some information regarding the sides of the triangle is given:
GiveN:
One side is 3 times the second side.Third side is 12 feet longer than the second side.As we can see that, two sides of the triangle are defined the second sides. It means First and third side can be expressed in the form of second side.
So let the second side be xThen,
First side = 3xAnd, third side = x + 12We know that, perimeters is the sum of the lengths of all sides of the triangle, So it can be written as:
[tex]3x + x + x + 12 = 32[/tex]
Solving it further,
[tex]5x + 12 = 32[/tex]
Subtracting 12 from both sides,
[tex]5x + 12 - 12 = 32 - 12[/tex]
[tex]5x = 20[/tex]
Dividing 5 from both sides,
[tex] \frac{5x}{5} = \frac{20}{5} [/tex]
[tex]x = 4[/tex]
Then,
First side = 3x = 12 feetSecond side = 4 feetThird side = x + 12 = 16 feetAnd we are done with the answer !!

Order from least to greatest 1 1/4, 1 2/3, 11/12
Help please, quick!
Answer:
[tex]\frac{11}{12}[/tex],[tex]1\frac{1}{4}[/tex],[tex]1\frac{2}{3}[/tex]
Step-by-step explanation:
It wants you to take these 3 fractions and arrange them from least to greatest.
The first thing I did was look for the fraction with no number in front of it.
[tex]\frac{11}{12}[/tex] is the only fraction that has no numbers in front of it. So
The second thing I did was look for the fraction that had the biggest number in front of it. I see that the remaining fractions have the same number in front.
So, I drew 2 circles. 1 of the circles I shaded in and the other I split into 4 equal halves. I shaded in one of the halves. These 2 circles represent [tex]1\frac{1}{4}[/tex].
The next thing I did was draw 2 more circles. I shaded in one of them and slit the other one into 3 equal halves. I shaded in 2 of the halves. These 2 circles represent [tex]1\frac{2}{3}[/tex].
Last, look at the 4 circles and ask yourself which one is the most shaded in. If you said [tex]1\frac{2}{3}[/tex] you are correct. This fraction is the biggest. Meaning that [tex]1\frac{1}{4}[/tex] is in the middle.

Point M is the midpoint of AB. The coordinates of point A are (-6, 1) and the coordinates of M are (-3,2).
What are the coordinates of point B?
The coordinates of point B are
Answer:
Let B(a,b) be x1, y1
A(-6,1) be x2,y2
midpoint M(-3,2) be (x,y)
using midpoint formula
(x,y)= [(x1+x2)/2, (y1+y2)/2)
(-3,2) = [(a-6)/2, (b+1)/2}
comparing corresponding value
-3 = (a-6)/2 (b+1)/2 = 2
-6= a-6 b+1=4
a=0 b=3
coordinates of B = (0,3)

Answer: If they start running at the same time, then it will take 30 minutes until they complete a lap together.
Step-by-step explanation:
Given: Stephanie can run one lap around a track in 5 minutes. Lisa can run one lap in 6 minutes.
If they start running at the same time, then the time they will take to complete a lap together = LCM (5,6)
prime factorization: 5=5 , 6 =2 x 3
So, LCM(5,6) = 5 x 2 x 3 = 30
Hence, it will take 30 minutes until they complete a lap together.

1) There are total 16 possible outcomes.
2) There are 6 possible outcomes for spinning two numbers that have sum greater than 5.
3) There are 4 possible outcomes for spinning the same number twice.
What is probability?" Probability is a branch of mathematics which represents the all possibilities. It is defined as the ratio of total number of favourable outcomes to the total number of outcomes of the particular event."
According to the question,
A spinner is divided into 4 equal sections that is 1 to 4.
As per the diagram,
All possible outcomes are as follow:
{ (1 ,1), ), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (2,4), (3,1), (3,2), (3,3), (3,4),(4,1),(4,2),(4,3), (4,4) }
1) Total possible outcomes = 16
2) Possible outcomes for spinning two numbers that have sum greater than 5 are (2,4), (3,3), (3,4), (4,2), (4,3), (4,4)
Therefore,
Total Possible outcomes for spinning two numbers that have sum greater than 5 = 6
3) Possible outcomes for spinning the same number twice are (1,1), (2,2), (3,3), (4,4)
Therefore,
Total Possible outcomes for spinning the same number twice = 4
Hence,
1) There are total 16 possible outcomes.
2) There are 6 possible outcomes for spinning two numbers that have sum greater than 5.
3) There are 4 possible outcomes for spinning the same number twice.

Describe the transformation used to map the graph of f(x) =x onto the graph of g(x)= 4x
Answer:
Step-by-step explanation:
5). Graph of the parent function f(x) = x has been given in the picture.
To map the graph the function 'f' onto the graph of function 'g',
f(x) = x
g(x) = 4x
A vertical stretch of the function 'f' by a scale of 4 is required.
6). Rule for a function to be translated by 'a' units down,
g(x) = f(x) - a
By this rule, if the function 'f' is translated 7 units down,
g(x) = f(x) - 7
g(x) = x - 7

1. what are the corrospoding parts of these two traingles? Write the corresponding angles and corresponding sides. 2. Assuming these triangles are simular, use the labels to write the ratios of corresponding sides that are proportional 3. Assuming these triangles are simular, write three statements relating the angle that are congruent
Answer:
See below.
Step-by-step explanation:
1. Look at the marks on the angles of both triangles.
Angles C and F have a single mark (that looks like an arc). They are congruent.
Angles A and D have a double mark (that look like arcs). They are congruent.
Angles B and E have a triple mark (that look like arcs). They are congruent.
Each pair of congruent angles is a pair of corresponding angles.
Corresponding angles:
<C and <F
<A and <D
<B and <E
For corresponding sides, we do this.
First, we write a statement of similarity.
Triangle ABC is similar to triangle DEF.
The statement of similarity must have the corresponding angles in the same order.
The order ABC and the order DEF matches corresponding angles.
The corresponding sides have the vertices of corresponding angles as their endpoints.
Corresponding sides:
AB and DE
BC and EF
AC and DF
2. For similar triangles, the ratios of the lengths of corresponding sides are equal.
The ratios of the lengths of corresponding sides are equal:
AB/DE = BC/EF = AC/DF
3.
<A is congruent to <D
<B is congruent to <E
<C is congruent to <F

Water is non viscous liquid and it has less density. The measure volume of water is 10.03 ml at 25 degree Celsius which is used to identify the standard deviation of the water.
Average volume of water 10.03ml.
Standard deviation is 0.0001 + 0.0001
Standard deviation is [tex]\sqrt{0.0002}[/tex] = 0.01.
Nancy decides to roll a dice three times. What is the probability that she will roll all even numbers?
Given:
Nancy decides to roll a dice three times.
To find:
The probability that she will roll all even numbers.
Solution:
If a dice is rolled, then the possible numbers are
Total number = {1,2,3,4,5,6} = 6
Even numbers = {2,4,6} = 3
Odd numbers = {1,3,5} = 3
Probability of getting an even number [tex]=\dfrac{\text{Even number}}{\text{Total numbers}}[/tex]
[tex]P(\text{Even})=\dfrac{3}{6}[/tex]
[tex]P(\text{Even})=\dfrac{1}{2}[/tex]
So, probability of getting all even numbers is
[tex]P(\text{All even})=P(\text{Even})\times P(\text{Even})\times P(\text{Even})[/tex]
[tex]P(\text{All even})=\dfrac{1}{2}\times \dfrac{1}{2}\times \dfrac{1}{2}[/tex]
[tex]P(\text{All even})=\dfrac{1}{8}[/tex]
Therefore, the required probability is [tex]P(\text{All even})=\dfrac{1}{8}[/tex].
The probability that Nancy will roll all even numbers will be:
"[tex]\frac{1}{8}[/tex]".
ProbabilityAccording to the question,
Number of times dice rolled = 3
Total numbers = {1, 2, 3, 4, 5, 6}
= 3
Even numbers = {2, 4, 6}
= 3
Odd numbers = {1, 3, 5}
= 3
Now,
The probability of getting even numbers will be:
= [tex]\frac{Even \ numbers}{Total \ numbers}[/tex]
= [tex]\frac{3}{6}[/tex]
= [tex]\frac{1}{2}[/tex]
hence,
The required probability be:
= P(Even) × P(Even) × P(Even)
= [tex]\frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}[/tex]
= [tex]\frac{1}{8}[/tex]
Thus the above answer is correct.
