Answer:
[tex] x = - 3 \frac{4}{15}[/tex]
Step-by-step explanation:
[tex]2x - \frac{1}{3} + 3 = x - \frac{3}{5} [/tex]
[tex] = > 2x - \frac{ 1 +9 }{3} = x - \frac{3}{5} [/tex]
[tex] = > 2x + \frac{8}{3} = x - \frac{3}{5} [/tex]
[tex] = > 2x - x = - \frac{3}{5} - \frac{8}{3} [/tex]
[tex] = > x = - \frac{9 - 40}{15} [/tex]
[tex] = > x = - \frac{49}{15} [/tex]
[tex] = > x = - 3 \frac{4}{15} (ans)[/tex]
Answer:
x = - [tex]\frac{49}{15}[/tex]
Step-by-step explanation:
Given
2x - [tex]\frac{1}{3}[/tex] + 3 = x - [tex]\frac{3}{5}[/tex]
Multiply through by 15 ( the LCM of 3 and 5 ) to clear the fractions
30x - 5 + 45 = 15x - 9 , that is
30x + 40 = 15x - 9 ( subtract 15x from both sides )
15x + 40 = - 9 ( subtract 40 from both sides )
15x = - 49 ( divide both sides by 15 )
x = - [tex]\frac{49}{15}[/tex]
A scoop used to measure
powdered drink mix is in
the shape of a cone with a
radius of 5 cm
What is the height of the scoop if its volume is 75pi cm cube
Answer:
9
Step-by-step explanation:
V=pi (r squared) (h/3)
75pi = 25pi (h/3)
Divide both sides by 25 pi
3= h/3
Multiply both sides by 3
h=9

Answer:
x = 62°
Step-by-step explanation:
the top-most angle in the top isosceles triangle must be 73° also
the third angle of the top isosceles triangle is (180 - 73 + 73) which is 34°
the left portion of the right angle must be 56°
you can find by using this equation: x + x + 56 = 180
2x = 124
x = 62

Answer:
Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)
Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)
Congruent: Choose one of the vertical angle pairs I listed above
Step-by-step explanation:
Vertical angles are diagonally across for each other and equal the same angle. You would get a better explanation if you looked up pictures.
Linear angles are two angles on a straight line that are divided by another line. Again, you would get a better explanation by looking at a visual
Congruent angles are equal to each other, and because there are no angle measures here, you would go with a vertical angle pair.

Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)

The numerator of the given fraction is 4 less than the denominator. If 5 is added to both numerator and denominator, the resulting fraction is equivalent to 5/7 . What is the original fraction? heeeeeeelp!!!
Answer:
5/9
Step-by-step explanation:
Let the denominator be k and thus numerator be 4 less than k or k - 4.
Fraction = (k - 4)/k
If 5 is added to both:
=> (k-4 + 5)/(k + 5) = 5/7
=> 7(k + 1) = 5(k + 5)
=> 7k + 7 = 5k + 25
=> 2k = 18
=> k = 9
Thus,
Fraction is (k-4)/k = (9-4)/9 = 5/9

Step-by-step explanation:
The equation for continuous compounding is [tex]A=A_oe^k^t[/tex]
where [tex]A[/tex] is the final amount, [tex]A_o=[/tex] the initial amount, [tex]k=[/tex] the interest rate, and [tex]t =[/tex] how much time is affecting it.
The equation for compound interest is [tex]A=A_o(1+\frac{r}{n} )^n^t[/tex]
where [tex]A=[/tex] the final amount, [tex]A_o=[/tex] the initial amount, [tex]r=[/tex] the interest rate, [tex]n =[/tex] the number of times the interest is applied per period (usually per year), [tex]t =[/tex] how many time periods elapsed (usually how many years the interest is applied).
Therefore you must set up all the equations with their respective units. If something is decaying, it will have a negative rate or a rate < 1. If something is growing, it will have a positive rate or a rate > 1.

What is scatter plot?
Scatter plot is the plot of graph in which the values of two variables plotted using their coordinates on the graph.
The average rate of change is the ratio of change in y values to the change in x values of the scatter plot.
The cost and customer rating of 13 televisions is shown on the scatter plot. The televisions are rated on a scale of 0 to 10.
Television Price (x) Rating (y) 1; 185, 3; 221, 10; 291, 2; 462, 4; 666, 5; 686, 4; 730, 5; 862, 7; 997, 10; 1,055, 9; 1,077, 8; 1,263, 7.61, Part A: Describe the association shown in the scatter plot.Here, the price and rating is increasing together in the scatter plot. Thus, there is a positive association.
Part B: Give an example of a data point that affects the appropriateness of using a linear regression model to fit all the data.Here, the television number 3 has the high rate with low price. This affect the appropriateness of using a linear regression model to fit all the data.
Part C: Give an example of a television that is cost-effective and rated highly by customers.The television number 3 which is rated at 10 but the cost of it has just $221. Thus, the television number 3 is cost-effective and rated highly by customers.
Thus, there is the positive association shown in the scatter plot and the television number 3 is cost-effective and rated highly by customers.

A fair tossed 10 times . Find the probability of obtaining (i) exactly four heads (ii) 3 heads and 7 tails (iii) at least one head
Answer:
0.205 ; 0.117 ; 0.999
Step-by-step explanation:
Using binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability of success, p = 0.5
P(x = 4) = 10C4 * 0.5^4 * 0.5^6
P(X = 4) = 0.205078125
B.) 3 heads and 7 tails
P(X = 7) = 10C7 * 0.5^7 * 0.5^3
P(X = 7) = 120 * 0.0009765625
P(X = 7) = 0.117
P(atleast one head)
P(x greater than equal to 1) = p(x =1) +... P(x = 10)
Using a binomial probability calculator :
P(x greater than equal to 1) = 0.999

Which of these systems of linear equations has no solution?
A
y = 3x + 8
y = 3x + 16
B
y = 3x + 16
y = 6x + 16
C
y = 3x + 8
y = 6x + 16
D
y = 3x + 8
y = 8x + 16
hurry please
Answer:
A is correct
Step-by-step explanation:
A has no solution because since the slopes are the same, setting both equations equal to each other will cancel out the slopes and result in 8=16, meaning no solution will make both sides equal to each other.
B does have a solution because of different slopes
C does have a solution because of different slopes
D does have a solution because of different slopes

How many more pounds does one of the heaviest bags weigh than one of the lightest bags?
Enter your answer as a fraction in simplest form by filling in the boxes.
lb
Answer:
2 1/2
Step-by-step explanation:
The heaviest bag weighs 4 pounds, and the lightest bag weighs 1 1/2.
4 can be converted to 8/2 and 1 1/2 can be converted to 3/2.
8/2-3/2=5/2.
5/2 converts to 2 and 1/2 or 2.5
The heaviest bags weigh than one of the lightest bags by 2.5 pounds.
What is fraction?A number expressed as a quotient, in which a numerator is divided by a denominator.
The heaviest bag weighs 4 pounds,
and the lightest one weighs 3/2 pounds
The difference between the heaviest and lightest one is:
= 4-3/2

Answer:
x = 6
Step-by-step explanation:
Tip: You want to isolate the x-variable on one side of the equation to find its value.
1) First, get rid of the radical signs on both sides of the equation by squaring both sides. This should leave you with 5x-7 = 3x+5.
2) Get the x-variables on one side by subtracting 3x from both sides, so the equation should be 2x-7=5.
3) Solve for x by adding 7 to both sides, so that your equation looks like this: 2x = 12.
4) Divide both sides by 2 and you will get x = 6. You can verify 6 as the x-value by plugging 6 back into the original equation.
I hope that helps! :)

Find the area of triangle ABC and the area of XYZ. AABC - AXYZ.
Answer:
ABC= 60 XYZ=540
Step-by-step explanation:
The area of a triangle is 1/2*base*height so for ABC we need to find the height first. To do this we use pythag theorem, and create the equation 13^2=5^2+height^2 rearranging this we can figure out that sqrt(height)=13^2-5^2. For the base we do 2*5 since there are two congruent line segments both equal to 5. Using this we can do 1/2*12*10=area of ABC
For XYZ we can do 1/2*30*36=area of XYZ, we can do 2*15 since there are 2 congruent 15 length line segments at the base.
Write a quadratic function whose zeros are 12 and 2 .
Answer:
The quadratic function is: [tex](x-2)(x-12)=0[/tex] and can be written as: [tex]x^2-14x+24=0[/tex]
Step-by-step explanation:
A quadratic function can typically be written in multiple forms, among which includes: (x-a)*(x-b)=0 where a, b can be any number
This quadratic function is solved for a and b, which represents the zeroes (or can be called roots) of the equation.
Given that the zeroes are already given, all that's need to write the quadratic function is to substitute a and b with the given zeroes:
Note: It doesn't matter which zeroes are substituted for a and b
(x-a)*(x-b)=0
(x-2)*(x-12)=0
Now, we can leave it in this form or expand the equation (often called the FOIL method):
(x-2)*(x-12)=0 Multiply each term with the other terms
[tex]x^2-2x-12x+24=0[/tex] Simplify by combining like terms
[tex]x^2-14x+24=0[/tex]
Thus, the quadratic function for zeroes 12 and 2 is: [tex]x^2-14x+24=0[/tex]
