Answer:
1
Step-by-step explanation:
First, we have to make the fractions improper.
To this we would need to multiply the denominator by the whole number and add it to the numerator. 2*4 is 8. 8 + 5 is 13. So for the first fraction, it will be 13/5. Let’s do the second fraction. 2*4 is 8. 8 + 3 is 11. So for the second fraction, it will be 11/2. Since the fractions have the same denominator, we will not have to do anything to them. Now, all you have to do is simple subtraction. 13 - 11 is 2. Since the denominators are the same, it will equal to 2. So the final answer is 2/2 or 1.
Solve the equations that have variables on both sides, find your answers in the legend below: *

Step-by-step explanation:
each angle in the hexagon=120°
angleSMN=120°
all triangles =180° in total
180-120= 60
60÷2 =30
remaining 2 angles = 30° each
Use the Pythagorean’s Theorem to find the missing side of each triangle
Answer:
131 is prime. So the answer is A
Step-by-step explanation:
Remark
x is one of the legs. The other one is √65
Equation
x^2 + (√65)^2 = 14^2
Solution
x^2 + 65 = 196 Subtract 65 from both sides
x^2 = 196 - 65
x^2 = 131 Take the square root of both sides.
√x^2 = √131
x = √131
Which sets of ordered pairs show equivalent ratios? (1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)
Given:
The different sets of ordered pairs in the options.
To find:
The sets of ordered pairs that show equivalent ratios
Solution:
The set of ordered pairs show equivalent ratios, if
[tex]\dfrac{y}{x}=k[/tex]
Where, k is a constant.
For option 1,
(1, 2), (2, 3), (4, 7)
[tex]\dfrac{2}{1}\neq \dfrac{3}{2}[/tex]
For option 2,
(2, 2), (4, 4), (6, 6)
[tex]\dfrac{2}{2}=\dfrac{4}{4}=\dfrac{6}{6}=1=k[/tex]
The set of ordered pairs (2, 2), (4, 4), (6, 6) show equivalent ratios.
For option 3,
(3, 1), (4, 1), (5, 1)
[tex]\dfrac{1}{3}\neq \dfrac{1}{4}[/tex]
For option 4,
(4, 1), (8, 2), (12, 3)
[tex]\dfrac{1}{4}=\dfrac{2}{8}=\dfrac{3}{12}=k[/tex]
The set of ordered pairs (4, 1), (8, 2), (12, 3) show equivalent ratios.
For option 5,
(2, 1), (4, 3), (5, 4)
[tex]\dfrac{1}{2}\neq \dfrac{3}{4}[/tex]
So, sets of ordered pairs in options 1, 3 and 5 does not show equivalent ratios.
Therefore, the correct options are 2 and 4.

Water makes up 3.4 of a person's weight. If a student weighs 100 lbs., how much of his weigh is water?
Answer:
75
Step-by-step explanation:
To determine how much of a persons weight is water, multiply 3/4 by their weight.
weight of water = weight x 3/4
100 x 3/4 0r 100 x 0.75 ( same thing)
75
The student weighs 75 lbs underwater
P.S it's not 3.4 it's 3/4 = 75% of our body is made up of water.

how many units apart are (3.1,-1) and (4.1,-1)
Answer:
The points are 1 unit apart.
Step-by-step explanation:
Given points are:
(3.1,-1) and (4.1,-1)
Distance formula is given by;
Distance between points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Where,
[tex](x_1,y_1)[/tex] = Coordinates of first point
[tex](x_2,y_2)[/tex] = Coordinates of the second point
Putting the values,
Distance = [tex]\sqrt{(4.1-3.1)^2 + (-1-(-1))^2[/tex]
Distance = [tex]\sqrt{(1)^2 + (-1+1)^2[/tex]
Distance = [tex]\sqrt{(1)^2}[/tex]
Distance = 1 unit
Hence,
The points are 1 unit apart.

Answer:
C
Step-by-step explanation:
Because lets say we have a point (1,2)
when reflecting this point over the y-axis it becomes (-1,2) so only the sign of the X value changes. Therefore by writing the system f(x)=g(-x) it changes the X value.
Find the output, y, when the input, x, is -1.
Answer:
the output is 3
Step-by-step explanation:
look for the point on the graph whose coordinate is -1
the point on the graph whose x coordinate is -1 is (-1,3)
so its 3

Brittany bought a dress that cost $22.50. If the sales tax is 6.5%, how much tax did she pay?
Answer:
$1.46
Step-step explanation:
We have to find out what 6.5% of 22.5 is, our keyword is of, so we're multiplying. Our equation is:
22.5 x 0.065 = 1.46
So our tax is $1.46

The length of a rectangle is 5(x+2) units. The width of the rectangle measures (2x-1) units. Set up and simplify an alegebraic expression to find the difference between the rectangles length and width.
Answer:
(3x + 11) units
Step-by-step explanation:
The length of a rectangle is 5(x+2) units.
The width of the rectangle measures (2x-1) units.
The difference between the rectangles length and width is given as:
Length - Width
(5(x + 2) - (2x - 1) units
(5x + 10 - 2x + 1) units
(5x - 2x + 10 + 1) units
(3x + 11) units
Therefore, the algebraic expression for the difference between the rectangles length and width is given as:
(3x + 9) units

I toss a coin 20 times. comes up "Heads" 7 times. What is the 1 point
relative frequency of getting a "Head"?
Someone help please I have to finish this quickly—
Answer in fraction form = 7/20
Answer in decimal form = 0.35
Answer in percent form = 35%
These are three ways to say the same thing.
======================================================
Explanation:
To get the relative frequency, you divide the number of times heads comes up out of the number of tosses total. Reduce the fraction as much as possible. In this case, 7 and 20 have no factors (other than 1) in common. So the fraction 7/20 cannot be reduced further.
The fraction 7/20 converts to the decimal form 0.35 after using a calculator or long division.
0.35 converts to 35% after moving the decimal over to the right two spots.

A clerk mixes a 15 pound a 15 pound bag of nuts for a customer. peanuts cost $ 5.50 5.50 per pound pound amd cashews cost $ 7.60 7.60 per pound . Pound . the total cost comes to $ 75.50 write a system of equations to find how many pounds of peanuts and how many pounds of cashew are in the bag
Answer:
[tex]x+y= 15---------------------1\\\\5.5x+7.6y= 75.5----------------2[/tex]
Step-by-step explanation:
Given data
let the number of peanuts be x
and the number of cashew be y
so
x+y= 15---------------------1
and
5.5x+7.6y= 75.5----------------2
Hence the system of equation is given as
[tex]x+y= 15---------------------1\\\\5.5x+7.6y= 75.5----------------2[/tex]

Find an expression, in terms of n, for the nth term of this sequence.
Answer:
aₙ = 2n² + n + 1Step-by-step explanation:
We observe that the difference of terms is 4, 7 and 15 and next level difference is 4. It means the sequence is quadratic.
We can compare this with simple quadratic sequence
1, 4, 9, 16and find out that doubling each term gives us
2, 8, 18, 32This is close to our sequence, write the terms as follows to find exact rule
The first term:
a₁ = 4 = 2*1² + 2 = 2*1² + 1 + 1The second term
a₂ = 11 = 2*2² + 3 = 2*2² + 2 + 1The third term:
a₃ = 22 = 2*3² + 4 = 2*3² + 3 + 1The fourth term:
a₄ = 37 = 2*4² + 5 = 2*4² + 4 + 1The nth term as per observation above is:
aₙ = 2n² + n + 1Answer:
