Answer:
x=7/3 or x=2.33
Step-by-step explanation:
9x^2 - 52x + 33 = -10x - 16
Okay, lets Start by converting this into standard form, which is: ax^2 + bx + c = 0.
Add 10x+16 on both sides of the equation, and simplifying.
9x^2 - 52x + 33 + 10x + 16 = -10x - 16 + 10x + 16
9x^2 - 42x + 49 = 0
Guess What! This equation is a Perfect Square Trinomial.
For a Perfect Square Trinomial, you will be able to take the square root of the first and third terms, and the coefficient of the second term will be twice the square root of the third term. The “sign” of your second term in your answer will be the same as the linear term sign.
So this is (3x*3x) + (3x * -7 * 2) + (7 * 7) = 0
So, we can rewrite this as (3x - 7)^2=0
Now, To solve, We can set each factor equal to 0, and solve.
*Since we have a Perfect Square Trinomial, You will get one solution, or value, for x.*
Add 7 on both sides.
3x - 7 = 0
+7 +7
----------------
3x=7
Divide by 3 on both sides.
3x/3 = 7/3
x=7/3
As a decimal: 2.33...

Answer:
721 hours
Step-by-step explanation:
Skills needed: Multiplication, Logical Reasoning
1) First, we need to gather information:
--> November has 30 days
--> There are 24 hours in each day
2) This means that there are:
[tex]24 * 30[/tex] = 720 days in November without counting daylight savings.
3) With daylight savings:
--> We add one extra hour, since we go one hour back. So that day, 1:59 would go back to 1:00, with an extra hour. So we add one to the total. [tex]720 + 1 = 721[/tex] is your answer
Hope this helps and have a nice day! :) :}
How do you know that 4 is the biggest whole number that divides both 36 and 80?

Step-by-step explanation:
What is 1/8 x 5/6 x 4/5 you will need paper.
Answer:
This would equal [tex]\frac{1}{12}[/tex]
Step-by-step explanation:
We do this by just multiplying straight across
Numerators go first
[tex]1*5*4[/tex]
This equals 20
Now the denominators
This would be done by
[tex]8*6*5[/tex]
This equals 240
now all together this is
[tex]\frac{20}{240}[/tex]
Simplify

Calculation: 0.166667=(-14)/(-84)
how do i find the missing length indicated
Answer:
The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two. The figure shows two right triangles that are each missing one side's measure.

13 = 1 + 35 + 7 = 1 + 3 + 57 + 9 + 11 = 1 + 3 + 5 + 79 + 11 + 13 + 15
A student wrote:
1 + 3 + 5 + ... + 365367 + 369 + ... + □
What value must replace the square for this fraction to equal 13 ?
Explain how you obtained the answer.
Answer:
The square is 731
Step-by-step explanation:
Let me try...13 , 1 + 35 + 7, 1 + 3 + 57 + 9 + 11 , 1 + 3 + 5 + 79 + 11 + 13 + 15 ...(1)
grab the main number in each sequence: 13,35,57,79,911,1113....
There is another arithmetic sequence: 1, 3, 5, 7, 9, 11 ....
a₁ = 1 aₙ = 2n - 1
365367 : 2n - 1 = 365 2n = 366 n = 183 ... 365367 is in the place 183 of the series sequence
Now let's check the number follow the underlined number in (1)
0 number follow 13, 1 number follow 35, 2 number follow 57, 3 follow 79 ....
0, 1, 2, 3, 4........ until n=183 should have 182 numbers followed 365367
Now this last sequence start with 369 (a₁) with a difference of 2 from term to term
a₁₈₂ = 2n + 367 = 2 x 182 + 367 = 731

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations
Step-by-step explanation:
-3x+7y = -18 ...1
4x-4y = 8 ...2
...1 × 4
-12x + 28y = -72 ...3
...2 × 3
12x - 12y = 24 ...4
...3 + ...4
28y - 12y = -72 + 24
16y = -48
y = -3
Replace y = -3 in ...2
4x - 4(-3) = 8
4x + 12 = 8
4x = 8 - 12
4x = -4
x = -1
Answer:
[tex]\huge\boxed{\boxed{(x,y)=(-1,-3)}}[/tex]
Step-by-step explanation:
multiply first equation by 4 and second by 3 respectively:
[tex] \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}[/tex]
combine the equations:
[tex] \underline{ \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}} \\ \displaystyle16y = - 48[/tex]
divide both sides by -48:
[tex] \displaystyle \: \frac{16y}{16} = \frac{ - 48}{16} \\ y = - 3[/tex]
substitute the value of y to the second equation
[tex] \displaystyle \: 4x - 4. - 3 = 8[/tex]
simplify multiplication:
[tex] \displaystyle \: 4x + 12 = 8[/tex]
cancel 12 from both sides:
[tex] \displaystyle \: 4x = - 4[/tex]
divide both sides by 4
[tex] \displaystyle \: \frac{4x}{4} = \frac{ - 4}{4} \\ x = - 1[/tex]
therefore our solution is
[tex]\displaystyle (x,y)=(-1,-3)[/tex]

from the point p(-2,4) if PQ is drawn perpendicular to line 7x-24y+10=0,find the eqaution of the lin PQ . also determine the length of PQ
Answer:
7y+24x = -12
Step-by-step explanation:
Equation of line PQ in point slope form is expressed as;
y -y0 = m(x-x0)
m is the slope of {Q
(x0, y0) is the point on the line
Given the line 7x-24y+10=0
Get the slope
-24y = -7x -10
y = -7/-24 x - 10/-24
y = 7/24 x + 5/12
Slope = 7/24
Slope of the line PQ perpendicular to it = -24/7
Substitute m = -24/7 and (-2, 4) into the formula;
y - 4 = -24/7(x+2)
7(y-4) = -24(x+2)
7y - 28 = -24x-48
7y + 24x = -40 + 28
7y+24x = -12
This gives the equation of the line PQ

A cylinder has diameter of 6 cm and a volume of 36 pi cm 3 . Find it's height and radius in centimeters
Answer:
Radius is 3
Height is 4
Step-by-step explanation:
First you'll have to find the radius
6/2=3
Then, use the formula Base (PI*radius squared)* height
To find the base, you'll have to use the radius, 3, times it by itself, 3, and get 9.
3*3=9
Then, multiply 9 by 3.14, first three digits of pi, and get 28.26
9*3.14=28.26
28.26=base
Now, you'll have to find the height
Since you know what the volume is 36 pi 3
36*3.14=113.04 <--volume without pi
Then, divide 113.04 (volume) by 28.26 (base) and get 4 (height)
113.04/28.26=4
That's why the radius is 3 and the height is 4
Answer:
r=3
h=4

The box and whisker plot represents the number of telemarketing calls received by households last month. Which statements are
correct?
A)
The mean of the data is 49.
B)
The median of the data is 49.
The least number of calls is 35.
D)
The third quartile is represented by 42.
E)
The mean cannot be determined by the box and whisker plot.
Given:
Consider the below figure attached with this question.
To find:
The correct statements about the given box and whisker plot.
Solution:
In a box plot, the left end of the box is first quartile and the right end of the box is third quartile. The line inside the box represents the median.
Left end point represents the minimum value and the right end point represents the maximum value.
From the given box plot, it is clear that
Minimum value = 35
First quartile = 42
Median = 49
Third quartile = 54
Maximum value = 57
The median of the data is 49. The least number of calls is 35. So, options B and C are correct.
The third quartile is represented by 54. So, option D is incorrect.
The mean cannot be determined by the box and whisker plot. So, option E is correct and option A is incorrect.
Therefore, the correct options are B, C and E.
