A = 6 - 35 B = 3x + 53
Solve for x then find the measure of A.
Answer:
A = 73°
Step-by-step explanation:
A + B = 180 because of alternating interior angles
Substitute each angle
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
Substitute A
A = 6x - 35
A = 108 - 35
A = 73

Solution:
The rationalisation factor for [tex] \frac{1}{ a - \sqrt{b} }[/tex] is [tex]a + \sqrt{b} [/tex]
So, let us apply it here.
[tex] \frac{1}{5 - \sqrt{2} } [/tex]
The rationalising factor for 5 - √2 is 5 + √2.
Therefore, multiplying and dividing by 5 + √2, we have
[tex] = \frac{1}{5 - \sqrt{2} } \times \frac{5 + \sqrt{2} }{5 + \sqrt{2} } \\ = \frac{5 + \sqrt{2} }{(5 - \sqrt{2})(5 + \sqrt{2} ) } \\ = \frac{5 + \sqrt{2} }{ {(5)}^{2} - ( \sqrt{2})^{2} } \\ = \frac{5 + \sqrt{2} }{25 - 2} \\ = \frac{5 + \sqrt{2} }{23} [/tex]
Answer:
[tex] \frac{5 + \sqrt{2} }{23} [/tex]
Hope you could understand.
If you have any query, feel free to ask.
Answer:
[tex]\frac{5+\sqrt{2} }{23}[/tex]
Step-by-step explanation:
To rationalise the denominator, multiply the numerator and denominator by the conjugate of the denominator.
the conjugate of 5 - [tex]\sqrt{2}[/tex] is 5 + [tex]\sqrt{2}[/tex] , then
= [tex]\frac{1(5+\sqrt{2}) }{(5-\sqrt{2})(5+\sqrt{2}) }[/tex] ← expand denominator using aFOIL
= [tex]\frac{5+\sqrt{2} }{25-2}[/tex]
= [tex]\frac{5+\sqrt{2} }{23}[/tex]
You are considering making a major purchase on your credit card. You should ask yourself the following questions, except which answer choice? a. Would it cost me less if I came up with a different purchasing plan? b. What else can I purchase to reach my full credit limit? c. Will I receive any incentives from my credit card company for making this purchase? d. How much will my purchase really end up costing if I don’t pay off the balance immediately? Please select the best answer from the choices provided A B C D.
Answer:
D would be the wisest choice.
Step-by-step explanation:
Consider the taxes and extra expenses the purchase may have. They may raise the actual payment, plus if you don't pay the balance immediately it'll keep growing and growing until you're in deeper debt.

Answer:
Constant: -17
Coefficient: 7
Number of terms: 3
Step-by-step explanation:
Constant: -17
-> This is the number that doesn't change. No matter what m or p is, -17 will be -17
Coefficient: 7
-> The coefficient is the number next to the variable. In this case, the number "with" (being multiplied by) p is 7
Number of terms: 3
-> There are three terms. A term includes positive/negative, number, variables, etc.

Brad bought a total of 9 CD's and tapes. The CD's cost $7 each and the tapes cost $6 each. He paid a total of $58. How many of each did he buy?
I ONLY NEED THE EQUATION...I can get the numbers of cans and peas I just need the equations to find the numbers
This is Algebra....please help me!!
Answer:
Step-by-step explanation:
Let the number of CD's = c
Let the number of tapes = t
Total number of CD's and tapes = 9
c + t = 9 --------------- (i)
Cost of 'c' CD's = 7*c = 7c
Cost of 't' tapes = 6*t = 6t
Total cost = $ 68
7c + 6t = 58 -----------------(ii)
Multiply the first equation by (-6) and then add the equations.
(i)* (-6) -6c - 6t = - 54
(ii) 7c + 6t = 58 {Now add. here t will be cancelled}
c = 4
Number of CD's = 4
Plugin c = 4 in equation (i)
4 + t = 9
t = 9 - 4
t = 5
Number of tapes = 5

I- $8,950
R- 6.85%
T- 6 years
Answer:
$4,368
Step-by-step explanation:
This is compound interest. and to calculate compound interest, which is (Amount - Principal) but we dont know the value for amount so we find the amount first by using the formula.
A = P ( 1 + R ) ^n
100
where p = principal ($8,950)
a = amount (?)
r = interest rate (6.85%)
n = time ( no of years) (6)
A = 8,950 ( 1 + 6.85 ) ^6
100 A = 8,950 ( 1 + 0.0685) ^6
A = 8,950 ( 1.0685) ^6
A = 8950 x 1.4881 A = 13,318
WE THEN FIND COMPUND INTEREST C = A MOUNT - PRINCIPAL
13, 318 - 8950 = $4,368

Answer:
a) (2,9); b) no points of intersection
Step-by-step explanation:
a)
Set the two equations equal to each other
7x - 5 = -2x + 13
Rearrange collecting like terms and solve
9x = 18
x = 2
Sub in x = 2 into either of the equations and it should yield the same result
Eq.1 y = 7(2) - 5 = 9
Eq.2 y = -2(2) + 13 = 9
Therefore the point of intersection is (2,9)
The graph confirms this result (see graph 1 with red and blue lines)
b)
As the gradients are the same, we can tell straight away that the two lines should be parallel and never intersect, but we'll try to solve it algebraically using the same method as in part a.
3x - 1 = 3x + 2
When rearranging, the x's cancel out which can be seen when subtracting 3x from both sides
-1 = 2
This equation is clearly incorrect. This means that there are no values of x at which the two equations are equal. Graphically, this means that the two lines are parallel and there are no points of intersection (see graph 2 with purple and green lines)

Find the perimeter and area of the figure pictured below.
Perimeter of the figure = 26.5 m
Area of the figure = 59.68 m².
What is the Perimeter of a Figure?Perimeter of a figure is the length around the borders of the figure.
Find the Perimeter of the Figure:
Perimeter = 3.9 + 7.4 + 10.6 + 4.6 = 26.5 m
Area of the Figure:
Decompose the figure into two rectangles, rectangle 1 and rectangle 2.
Area of rectangle 1 = length × width = 10.6 × 4.6 = 48.76 m².
Area of rectangle 2 = length × width = 3.9 × (7.4 - 4.6) = 10.92 m².
Area of the figure = 48.76 + 10.92 = 59.68 m².

how are the two coin stacks different from each other?
does either stack of coins resemble a geometric solid? if so which stack and what solid?
how do the heights of the two stacks compare?
how do the volume of the two stacks compare? explain your reasoning.
Question 1
You probably agree that it's fairly obvious that the stack on the right is slanted, while the stack on the left is straight up and down (more or less).
--------------
Question 2
The stack on the left resembles a cylinder. It might help to wrap the coins in a paper casing to better see this.
--------------
Question 3
The heights of each stack appears to be the same. This is assuming both stacks have the same number and type of coins.
--------------
Question 4
The two stacks have the same volume. This may seem a bit strange, but if both stacks have the same number and type of coins, then each of the individual coins has the same volume. When put together, the overall 3D solids will have the same volume as well. It doesn't matter if we slanted one of the stacks or not.

Mr. Appleman own a rectangle apple orchard that measure 18m long and has a diagonal length of 25m. What is the width of his Orchard to the nearest the tenth of a metre?
Answer:
length = 17.3 m
Step-by-step explanation:
Rectangles have four right angles, so the diagonal and its sides will form a right triangle. This allows us to use the Pythagorean Theorem to find the length.
l^2 + 18^2 = 25^2
sqrt l^2 = sqrt (25^2 - 18^2), where l = 17.349 = 17.3 m
