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.
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
Solve the triangle for which ∠ A = 30 ∘ , ∠ B = 45 ∘ , and a = 20 . Round to the nearest whole number. Do not use a decimal point or spaces in your answer or it will be marked incorrect. b = ∘
Answer:
[tex]b=20\sqrt{2}[/tex] units
Step-by-step explanation:
Recall the Law of Sines
[tex]\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}[/tex]
Solve for side "b" given ∠A, ∠B, and side "a"
[tex]\frac{sinA}{a}=\frac{sinB}{b}\\ \\\frac{sin(30^\circ)}{20}=\frac{sin(45^\circ)}{b}\\ \\ bsin(30^\circ)=20sin(45^\circ)\\\\b(0.5)=20(\frac{\sqrt{2}}{2})\\ \\0.5b=10\sqrt{2}\\\\b=20\sqrt{2}[/tex]
Therefore, [tex]b=20\sqrt{2}[/tex] units

There are 8 books lettered A-H on
the shelf. If Scott randomly chose
two books, what is the probability
that he chose books A and B?
Therefore, the probability that Scott chose books A and B is 1/28.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 means that the event will not occur and 1 means that the event is certain to occur. The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in many areas of mathematics, science, economics, and everyday life to help make predictions, decisions, and inferences.
Here,
The total number of ways Scott can choose 2 books out of 8 books is given by the combination formula:
C(8,2) = 8! / (2! * 6!) = 28
This means there are 28 possible pairs of books he could choose.
The probability that he chose books A and B is 1 out of 28 because there is only 1 way to choose books A and B out of the 28 possible pairs:
P(A and B) = 1/28

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]

There is nothing in the given requirement that means x and y must have the same sign. If the signs are different, then the value of the expression is less than 1, rather than greater than 1.

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]

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.

B. 10
Step-by-step explanation:
This pair of triangles follows a scale factor. A scale factor is the factor that can get you an exact copy of a triangle, but with bigger or smaller side lengths. In this case, the scale factor is 2 (doing 12/6 on the left side is 2), and dividing that by 20 to get 10. Because we want the smaller triangle, we divide, not multiply. (you could also multiply by 1/2)

Answer 5 :-We have,
[tex]\sf{ HE = 2x cm \: and \: OR = ( x + 5)cm}[/tex]
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
Answer 7 :-We have,
[tex]\sf{ HZ = 4a - 5 \:and \:RZ = 3a + 5 }[/tex]
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]
The measurement of HZ is 35 cm
Hence, Option C is correct
Answer 8 :-We have ,
One diagonals = 5x - 47
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 .
Hence, Option B is correct
