Step-by-step explanation:
is 7.2 a rational number
Step-by-step explanation:
A decimal is a number that represents a fractional part of a whole. For example, the decimal 0.25 represents 25/100. Numbers with decimals are not integers because an integer is defined as a whole number with no fractional part.

Answer:
The given three sides can not form a triangle.
Step-by-step explanation:
Given three sides:
Length of first side = 7.7 cm
Length of second side = 4.0 cm
Length of third side = 1.7 cm
To find:
Whether these three sides can possibly be the three sides of a triangle ?
Solution:
Here, we can use the property of sides of a triangle:
The sum of the lengths of any two sides must be greater than the length of third side.
Now, let us try to verify this property.
Length of first side + Length of second side = 7.7 + 4.0 = 11.7 cm which is greater than the length of third side i.e. 1.7 cm
Length of first side + Length of third side = 7.7 + 1.7 = 9.4 cm which is greater than the length of second side i.e. 4.0 cm
Length of second side + Length of third side = 4.0 + 1.7 = 5.7 cm which is not greater than the length of first side i.e. 7.7 cm
Therefore, the property does not hold true.
It can be concluded that, the given three sides can not form a triangle.
Answer:
isyllus is correct
they can not from a triangle

How many diagonals can be constructed from one vertex of an n-gon? State your answer in terms of n and, of course, justify your answer.
IM REPOSTING THIS QUESTION, BUT THIS TIME FOR 15 POINTS!!!!!!!!!!!!!!
PLEASE HELP :)
Answer:
[tex]The \ total \ number \ of \ distinct \ diagonals \ in \ a \ polygon \ with \ n \ sides= \dfrac{n \times (n - 3)}{2}[/tex]
Step-by-step explanation:
A diagonal is defined in geometry as a line connecting to two non adjacent vertices.
Therefore, the minimum number of sides a polygon must have in order to have a diagonal n - 3 sides as the 3 comes from the originating vertex and the other two adjacent vertices
Given that the polygon has n sides, the number of diagonals that can be drawn from each of those n sides gives the total number of diagonals as follows;
Total possible diagonals = n × (n - 3)
However, half of the diagonals drawn within the polygon are the same diagonals drawn in reverse. Therefore, the total number of distinct diagonals that can be drawn in a polygon is given as follows;
[tex]The \ total \ number \ of \ distinct \ diagonals \ in \ a \ polygon \ with \ n \ sides= \dfrac{n \times (n - 3)}{2}[/tex]

What is the slope?????
Answer:
Slope= 2/3
Step-by-step explanation:
Here are our coordinates:
x1= 20
y1= 60
x2= 50
y2= 80
Now we use the slope formula-- y2-y1/x2-x1.
Now we plug in the numbers!
80-60= 20
=20/30
50-20= 30
Now we simplify: 20/10= 2
30/10=3
Thus your answer: 2/3
Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate (Below).
Machine A covers 5/8 square feet in 1/4 hour or Machine B covers 2/3 square feet in 1/5 hour.
Answer:
Unit Rate of Machine A = 2.5 square feet per hour
Unit Rate of Machine B = 3.333 square feet per hour.
The unit rate of Machine B is greater than unit rate of machine A.
Step-by-step explanation:
The unit rates for both machines need to be calculated first.
The unit rate will be calculated as:
[tex]Unit\ rate = \frac{Area\ covered}{Time}[/tex]
For Machine A:
Area Covered = 5/8
Time = 1/4
The unit rate will be:
[tex]U_A = \frac{\frac{5}{8} }{\frac{1}{4} } \\Using\ rule => \frac{\frac{a}{b} }{\frac{c}{d} } = \frac{a}{b} * \frac{d}{c}\\=\frac{5}{8} * 4 \\= \frac{5}{2} = 2.5\ square\ feet\ per\ hour[/tex]
For Machine B:
Area Covered = 2/3
Time = 1/5
[tex]U_B = \frac{\frac{2}{3}}{\frac{1}{5}}\\= \frac{2}{3} * \frac{5}\\= \frac{10}{3}\\= 3.33...\ square\ feet\ per\ hour[/tex]
As it can be seen that unit rate for Machine B is greater than Unit Rate of Machine A.
Hence,
Unit Rate of Machine A = 2.5 square feet per hour
Unit Rate of Machine B = 3.333 square feet per hour.
The unit rate of Machine B is greater than unit rate of machine A.
Find the slope of the ordered pair. A(4,6) B(5,8)
Answer:
The slope is 2Step-by-step explanation:
Step one:
we are required to find the slope of the given data points
A(4,6) B(5,8)
hence the x and y values correspond to
x1=4
y1=6
x2=5
y2=8
Step two:
Required is the slope which is
slope= y2-y1/x2-x1
Slope=8-6/5-4
Slope= 2/1
Hence the slope of the ordered pair is 2
A video game is on sale at Amazon for 30% off the original price of $28.50. Both Pat and Henri want to purchase the game, but they only have $22 each. They each have to pay 10% sales tax. Pat and Henri have different strategies to calculate the price and decide if they have enough money to get the game. Pat takes 30% of $28.50 and subtracts that from the original price. She takes 10% of the sale price and adds it to the sale price to find the total amount she would have to pay. Henri finds 70% of the original price and then calculates 110% of the sale price. Will Pat's strategy calculate the correct total? Explain the calculations. Will Henri's strategy calculate the correct total? Explain the calculations. Do they each have enough to purchase the game?
Explain your answers using complete sentences and show your work. (10 points)
Your answer:
Answer:
Step-by-step explanation:
Explanation:
Step one:
The original price of the video game= $28.5
Cash at hand= $22
Discount= 30%
Tax= 10%
1. Pat's strategy
Amount discounted
=30/100*28.5
=0.3*28.5
=$8.55
28.5-8.55
=$19.95
Amount of tax added
=10/100*28.5
=0.01*28.5
=2.85
=17.15+2.85
=$22.8
Hence going by Pat's strategy, the total amount to be paid is
=$22.8
2. Henri's strategy
=70/100*28.5
=0.70*28.5
=$19.95
110% of $28.5
=110/100*28.5
=1.1*28.5
=$31.35
the tax is
31.35-28.5
=$2.85
i. Hence by Henri's strategy, the sales price with tax is
=19.95+2.85
=$22.8
ii. Yes Pat's strategy will compute the correct total,
30% of $28.5 is $8.55 which is the amount to be deducted as a discount
10% of $28.5 is $2.85 which is the amount to be added as tax
Hence the total amount to be paid is $22.8
iii Yes Henri's strategy also gave the correct total
70% of 28.5 is $19.95
110% of 28.5 of tax is the same as adding 10% of 28.5 to 28.5
= 31.35, substracting the original price we got the tax added
which is $2.85
iv. No, they both don't have enough money to purchase the video game,
because they only have $22and the game is to be sold for $22.8
Janet can plant nine feet of carrots in 15 minutes while her daughter Amy can plant 17 feet of carrots in half an hour.
Who plants carrots more quickly? Show work
Answer:
Step-by-step explanation:
In order to find who is more efficient at planting carrots, we want to put both ratios in terms of the same amount of time.
For simplicity, lets see how many carrots each can make in 1 hour.
[tex]Janet:\\9ft \: in \: 15 \:minutes[/tex]
[tex]\frac{9ft}{15min} = \frac{xft}{60min}\\x = \frac{60*9}{15} = 36[/tex]
Janet can plant 36 feet of carrots in one hour
[tex]Amy:\\\frac{17ft}{30min} = \frac{xft}{60min}\\x = \frac{17*60}{30} = 34[/tex]
Amy can plant 34 feet of carrots in one hour
So, Janet can plant carrots more quickly

Find the whole number that satisfies all of the following conditions it is a whole number between 1 and 100 inclusive 10% of the number is greater than 1 but less than 7 1/3 of the number is a square number the number is not a multiple of 6
Answer:
Step-by-step explanation:
The question is a little unclear in this statement.
10% of the number is greater than 1 but less than 7 1/3 . Do you mean 7 1/3%
List all the perfect squares between 1 and 100
1 4 9 16 25 36 49 64 81 and 100
The number is not a multiple of 6 which lets out 36
The number is greater than one because 10% of the number is greater than 1.
7.33333% = 7.333 / 100 * N
That lets out 100 which 7.3333% = 7.3333
So what do we have left?
4 9 16 25 49 64 81
That's as far as I can get you. Perhaps if you clarify what is unclear, we might be able to take it further. Leave a statement, and I will revise my answer.
Help!! Use the figure to find the measures of the numbered angles.
Answer:
1, 3, 6 = 61°
2, 4, 5, 7 = 119°
Answer:
m∠1 = 61°
m∠2 = 119°
m∠3 = 61°
m∠4 = 119°
m∠5 = 119°
m∠6 = 61°
m∠7 = 119°
Step-by-step explanation:
Ah transversals, a simple subject which was taught to be so complicated.
Basically its a complicated way of demonstrating parallelism and intersection of two straight lines.
m∠6 is equal to angle 61 due to a rule of vertical angle; basically the mirroring properties of two intersecting lines. If you'd like this subject broken down further leave me a comment.
Corresponding angles are ∠2 and ∠5, and ∠3 and 6∠. It's easier to visualize them on their own. To help with this I'll provide a cleaned-up visual.
They are equal to each other just as 61 is equal to m∠1
the 61 and the m∠5 will add up to 180 because straight lines are straight and 180 degrees.
