So first of all we have: 180-120=60 => this is the value of angle(BCA)
=> we know that a triangle has 180 degree in total =>
Now we will have to add all angles,their sum will be equal to 180.
=> (2x+28)+(3x-13)+60=180
2x+28+3x-13=180-60
5x+15=120
5x=105
x=105/5
x=21
=> m(BAC) = 2x+28=29*2+28=58+28=86 degree.
The wholesale price for a pair of shoes is $6.50. A certain department store marks up the wholesale price by 40%. Find the price of the pair of shoes in the
department store
Round your answer to the nearest cent, as necessary.
Answer:
$9.10 dollars
Step-by-step explanation:
The original price of the shoes is $6.50, so we want to add 40% to that. There are two ways to do this.
Method 1:
Find 40% of 6.50, and add it to 6.50.
[tex]6.5*0.4= 2.6\\6.5+2.6=9.1[/tex]
Method 2:
Multiply 6.5 by 1.4 (including the original percent of 100 and adding 40 percent to it)
[tex]6.5*1.4=9.1[/tex]

Answer:
1.7 x 10= 17 (moving one decimal point to the right)
1.7 x 100=170 (moving two decimal points to the right)
1.7 x 1000= 1700 (moving 3 decimal points to the right)
Reflect: The decimal changes depending on the number of zeros in each multiple of ten that it is multiplied by. If it is multiplied by 10 for instance, the decimal is moved one place to the right since there is one 0, if by 100 then it is moved two places to the right since there are 2 zeros, and if by 1000 then it is moved 3 places to the right for the 3 zeros.
An online store holds a sale. Of the 500 customers who make purchases during the sale, 120 use a coupon. What percent of the customers do not use a coupon?
Total no of customers = 500
Used coupon = 120
Not used coupon = 500 - 120 = 380
We need to find the percentage of the customers do not use a coupon. It can be given by :
380/500×100
So, there are 76% of the customers that do not use a coupon.

A manufacturer drills a hole through the center of a metal sphere of radius R. The hole has a radius r. Find the volume of the resulting ring.
The volume of the resulting ring is (4/3)π(R³ - r³)
Volume
The volume of an object is the amount of space occupied by the object in three dimension.
The volume (V) of a sphere is given by:
V = (4/3)πr³
Where r is the radius of the sphere.
For the sphere with radius R, volume is:
V = (4/3)πR³
The hole with radius r, has a volume of:
V = (4/3)πr³
Hence volume of the ring = (4/3)πR³ - (4/3)πr³ = (4/3)π(R³ - r³)
The volume of the resulting ring is (4/3)π(R³ - r³)

If given in the following expression, find the value of
(x^3 + y^3):(x^3-y^3)
If (x^2+y^2)/(x^2 -y^2)= 17 /8
Step-by-step explanation:
Given that:
{(x²+y²)/(x²-y²)} = 17/8
On applying cross multiplication then
since, (a/b) = (c/d) ⇛a(d) = b(c)
Where, x = x²+y², b = x²-y², c = 17 and d = 8
So,
⇛17(x²-y²) = 8(x²+y²)
Multiply the number outside of the brackets with variables in the brackets on both LHS and RHS.
⇛17x²-17y² = 8x²+8y²
⇛17x²-17y² - 8x²-8y² = 0
⇛17x²- 8x² - 17y² - 8y² = 0
⇛9x² - 25y² = 0
⇛9x² = 25y²
⇛9/25 = y²/x²
⇛25/9 = x²/y²
⇛x/y = √(25/9)
⇛x/y = √{(5*5)/(3*3)}
⇛x/y = 5/3
Therefore, x:y = 5:3
Let x = 5a and y = 3a
Now, (x³+y³):(x³-y³)
= {(x³+y³)/(x³-y³)} = [{(x+y)(x²-xy+y²)}/{(x-y)(x²+x-y+y²)}]
= [{(5a)³ + (3a)³}/{(5a)³ - (3a)³}]
= [{(5*5*5*a*a*a) + (3*3*3*a*a*a)}/{(5*5*5*a*a*a) - (3*3*3*a*a*a)}]
= {(125a³ + 27a³)/(125a³ - 27a²)}
= {(152a³)/(98a³)}
= 152/98
Write the obtained fraction in lowest form by cancelling method.
= {(152÷2)/(98÷2)}
= 76/49
Therefore, , (x³+y³):(x³-y³) = 76/49
Answer: Hence, the required value of (x³+y³):(x³-y³) is 76/49.
Please let me know if you have any other questions.
Answer:
76:49 or 49:76
Step-by-step explanation:
The second relation gives an expression for y in terms of x:
[tex]\dfrac{x^2+y^2}{x^2-y^2}=\dfrac{17}{8}\\\\8x^2+8y^2=17x^2-17y^2\qquad\text{cross multiply}\\\\25y^2=9x^2\qquad\text{add $(17y^2-8x^2)$}\\\\5y=\pm3x\qquad\text{take the square root}\\\\y=\pm\dfrac{3}{5}x\qquad\text{divide by 5}[/tex]
Substituting into the expression we want the value of, we can factor out x^3 to get ...
[tex](x^3+y^3):(x^3-y^3)=(1\pm(3/5)^3):(1\mp(3/5)^3)=(125\pm27):(125\mp27)\\\\=152:98\text{ or }98:152=\boxed{76:49\text{ or }49:76}\m[/tex]

Carly is playing her violin at a music festival and earns $8 for each song she plays. Maxwell is playing at a local coffee shop and earns $10 for each song he plays, but also has to pay a $50 fee to play there.
Answer:
If you wanted to know how much songs Maxwell will have to play to pay the fee to play there, ($50 dollars) he will have to play 5 songs.
Step-by-step explanation:
The question to the awnser is how much can 10 go into 50. That means you have to divide 50 by 10. You can put 10 5 times into 50, and you can make sure of that by timing 10 by 5. I have no idea though what you need. Sorry if im saying somthing different than wht you want.
The sum of two numbers is sixteen. One number is forty less than three times the other. Find the numbers.
Answer:
y = 14 x = 2
Step-by-step explanation:
what we know:
x + y = 16
x = 3y - 40
3y - 40 + y = 16
4y - 40 = 16
add 40 to both sides
4y = 56
y = 14
x = 3(14) - 40
x = 42 - 40
x = 2

Warren wanted to save money to purchase a new car. He started by saving $1 on the first of January. On the first of February, he saved $4. On the first of March, he saved $16. So on the first day of each month, he wanted to save four times as much as he did on the first day of the previous month. If Warren continues his savings pattern, how much will he need to save on the first day of July?
On the first day of July he will need to save $ (your answer here)
.
Answer:
On the first day of July he will need to have saved $4098 for his new car.
Step-by-step explanation:
So we know that on March he save $16 and the amount he needs to save each month increases by 4 times the previous month’s amount.
We can conclude then for April he would need to have saved $64.
In May, if we repeat the pattern of multiplying the previous month’s savings by 4, Warren would have saved $256.
We will continue this pattern for June and July.
In July we will multiply $1024 (total saved in June) by 4 to find that in July, Warren will have needed to save $4098

A randomly generated list of integers from 0 to 4 is being used to simulate an
event with the numbers 2 and 3 representing a success. What is the
estimated probability of a success?
Answer:
2/5
Step-by-step explanation:
No of items =5(0,1,2,3,4)
No of favourable conditions =2(2,3)
Gk, probability =2/5
Answer:
40% chance of success
Step-by-step explanation:
The possible integers chosen are 0, 1, 2, 3, and 4.
Since the numbers are randomly chosen and the numbers 2 and 3 represent a success, and the numbers 0, 1, and 4 represent a failure, and there are 5 possible outcomes, there is a 2/5 chance of success. Therefore, you have an estimated 40% chance of a success.

We know that,
Parallelogram has opposite sides parallel and equal.From above property,
[tex]\sf{ HE = OR }[/tex]
[tex]\sf{ 2x = x + 5}[/tex]
[tex]\sf{ 2x - x = 5}[/tex]
[tex]\sf{ x = 5}[/tex]
Thus, The value of x is 5cm
Therefore,
The value of HE
[tex]\sf{ = 2x}[/tex]
[tex]\sf{ = 2× 5}[/tex]
[tex]\sf{\red{ = 10 cm}}[/tex]
The measurement of HE is 10 cm
Hence, Option A is correct
Answer 6 :-We have,
[tex]\sf{m}{\sf{\angle{HER = 5y - 26° \: and\: m }}}{\sf{\angle{ ROH = 2y + 40°}}}[/tex]
In parallelograms, Opposite angles are equalFrom above property,
[tex]\sf{m}{\sf{\angle{HER = }}}{\sf{\angle{ ROH}}}[/tex]
[tex]\sf{ 5y - 26° = 2y + 40°}[/tex]
[tex]\sf{ 5y - 2y = 40 + 26}[/tex]
[tex]\sf{ 3y = 40 + 26}[/tex]
[tex]\sf{ y = 66/3}[/tex]
[tex]\sf{ y = 22°}[/tex]
Thus, The value of y is 22°
Therefore,
The measurement of Angle HER
[tex]\sf{ = 5 × 22 - 26 }[/tex]
[tex]\sf{ = 110 - 26 }[/tex]
[tex]\sf{\red{= 84° }}[/tex]
The measurement of angle HER is 84°
Hence option D is correct

The diagonals of parallelogram are equal in length Here, RZ is the bisector of diagonal HR[tex]\sf{ 4a - 5 = 3a + 5 }[/tex]
[tex]\sf{ 4a - 3a = 5 + 5}[/tex]
[tex]\sf{ a = 10}[/tex]
Thus, The value of a is 10
Therefore,
The measurement of HZ
[tex]\sf{ = 4 × 10 - 5 }[/tex]
[tex]\sf{ = 40 - 5 }[/tex]
[tex]\sf{\red{= 35 \: cm }}[/tex]

Another diagonal = 2x + 34
In isosceles trapezoid, Diagonals are equal in length.From above property,
[tex]\sf{ 5x - 47 = 2x + 34 }[/tex]
[tex]\sf{ 5x - 2x = 34 + 47}[/tex]
[tex]\sf{ 3x = 81 }[/tex]
[tex]\sf{ x = 81/3 }[/tex]
[tex]\sf{ x = 27}[/tex]
Thus, The value of x is 27
Hence, Option A is correct
Answer 9 :-We have,
The sides of parallelogram GAME are (7x - 1 ) , ( 5x + 10 ) , (6x) , ( 7x - 2 )
In parallelogram, Opposite sides are equalFrom above property,
[tex]\sf{ 7x - 1 = 6x }[/tex]
[tex]\sf{ 7x - 6x = 1 }[/tex]
[tex]\sf{ x = 1 }[/tex]
[tex]\sf{ 5x + 10 = 7x - 2}[/tex]
[tex]\sf{ 7x - 5x = 10 + 2 }[/tex]
[tex]\sf{ 2x = 12}[/tex]
[tex]\sf{ x = 12/2 }[/tex]
[tex]\sf{ x = 6 }[/tex]
Thus, measurements of parallelogram GAME in inches is 1 and 6 .

[tex]\sf{ OE = 2ES ( OS = ES bisector}[/tex]
[tex]\sf{ OE = 2 × 18 }[/tex]
[tex]\sf{ OE = 36cm }[/tex]
Thus, The value of OE is 38 cm
Therefore,
[tex]\sf{ OE = NP }[/tex]
[ Diagonals of the given rectangle ]
[tex]\sf{\red{NP = 36 cm }}[/tex]
Thus , The value of NP is 36 cm
Hence, Option C is correct
