Step-by-step explanation:
6/9 * 3
First you can either simplify this to make it easier or directly multiply. Simplify it by dividing 3 on the 9.
6/3=2
Or you can multiply and it would be 18/9, because 6*3=18.
18/9=2

Answer:
MP = Rs. 1500
SP = Rs. 1230
Step-by-step explanation:
Let the Cost Price (CP) be x
Then Market Price (MP):
MP = x+ 20% = 1.2xDiscounted Selling Price (SP):
SP = MP - 18% = 0.82*1.2x = 0.984xSince the difference between CP and SP is Rs.20:
x - 0.984x = 200.016x = 20x= 20/0.016x = 1250Then:
MP = 1.2*1250= Rs. 1500and
SP = 1500*0.82 = Rs. 1230I need help with this!!!

Write an absolute value equation that has solution x = -6 and x = 10
Answer:
|x - 2| = 8
Step-by-step explanation:
The midpoint between -6 and 10 is;
(-6 + 10)/2 = 4/2 = 2
This means that the distance between 2 and either -6 or 10 will be 8.
Now, the absolute value equation will have to say that the distance between x and 2 is 8.
Thus, plugging those numbers into the pattern of |x - m| = b. Where m is the midpoint and b is the distance from midpoint to either values of x.
This gives us the absolute value equation:
|x - 2| = 8

Step-by-step explanation:
The formula is:
[tex]PV = P (\frac{1 - ( 1 + r ) ^{-n}}{r})[/tex]
[tex](100+x)\frac{(1+\frac{0.04}{4})^{40}-1 }{\frac{0.04}{4} }(1+\frac{0.04}{4})^{40}[/tex] [tex]+100\frac{(1+\frac{0.04}{4})^{40}-1 }{\frac{0.04}{4} }=50000[/tex]
[tex](100+x)(\frac{(1+0.01)^{40} -1}{0.01}) (1+0.01)^{40}[/tex] [tex]+(100)(\frac{(1+0.01)^{40} -1}{0.01} )=50000[/tex]
(100+x) [(1.488864 - 1) / 0.01] (1.488864) + (100) [(1.488864 - 1) / 0.01] = 50000
(100+x) [(0.488864 / 0.01)] (1.488864) + (100) (0.488864 / 0.01) = 50000
(100+x) (48.8864) (1.488864) + (100) (48.8864) = 50000
(100+x) (48.886373) (1.488864) + 4888.64 = 50000
(100+x) (72.785161) + 4888.64 = 50000
7278.5161 + 72.785161 x + 4888.64 = 50000
12167.1561 + 72.785161 x = 50000
72.785161 x = 50000 - 12167.1561
72.785161 x = 37832.8439
x = 37832.8439 / 72.785161
x = 519.787871
x = $519.79
Explain the 2 different answers you can get when solving an equation and the variable is eliminated.
When you're solving an equation, there are three possibilities. Two of which are chosen if your statement is true or not.
If you're able to get x alone, there is one solution. However, If all of the variables are eliminated and you're left with a false statement, that will be no solution. Example: 1=5? False.
If all of the variables are eliminated and you're left with a true statement, that solution is all real numbers. Example: 5=5? True.

Step-by-step explanation:
find the value of X and y from the figure
Answer:
180° = x + (2x -15)
180°=3x-15
3x = 195
x =65°
x + y = 180°
65+ y= 180°
y = 115°
Answer:
x = 65, y = 115
Step-by-step explanation:
x and 2x - 15 are adjacent angles and supplementary, thus
2x - 15 + x = 180
3x - 15 = 180 ( add 15 to both sides )
3x = 195 ( divide both sides by 3 )
x = 65
y and 2x - 15 are congruent ( alternate angles ), thus
y = 2x - 15 = 2(65) - 15 = 130 - 15 = 115

Question 1 (2 points) The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 264 centimeters in 11 seconds. a. What is the time in seconds the toy robot moves when the total distance is 408 centimeters? Seconds b. What is the distance in centimeters the toy robot moves after 3 seconds? Centimeters
Answer:
a. [tex]T = 17s[/tex]
b. [tex]D = 72cm[/tex]
Step-by-step explanation:
Given
Direct Variation
[tex]Distance(D)\ \alpha\ Time (T)[/tex]
D = 264 cm when T = 11 s
Calculating (a)
First, the constant of variation (k) as to be calculated;
Since, there exist a direct proportion; then,
[tex]D\ \alpha\ T[/tex]
[tex]D = kT[/tex]
Make k the subject of formula
[tex]k = \frac{D}{T}[/tex]
D = 264 cm when T = 11 s; So
[tex]k = \frac{264}{11}[/tex]
[tex]k = 24[/tex]
So: Solving for (a)
[tex]D = 408[/tex]
Substitute 408 for D and 24 for k in [tex]D = kT[/tex]
[tex]408 = 24 * T[/tex]
Divide both sides by 24
[tex]\frac{408}{24} = T[/tex]
[tex]T = \frac{408}{24}[/tex]
[tex]T = 17s[/tex]
Hence, time to move a distance of 408cm is 17s
Calculating (b)
[tex]T = 3[/tex]
Substitute 3 for T and 24 for k in [tex]D = kT[/tex]
[tex]D = 24 * 3[/tex]
[tex]D = 72cm[/tex]
Hence, distance covered in 3 seconds is 72cm

b) The number of tiles in figure 100 will be 601 tiles
What is Arithmetic Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the figure 100 be represented as = a₁₀₀
Let the number of tiles in the first figure be a₁
The value of a₁ = 7 tiles
Let the number of tiles in the second figure be a₂
The value of a₂ = 13 tiles
So , the common difference of the arithmetic sequence is d
d = second term - first term
d = 13 - 7
d = 6
Now , the value of figure a₁₀₀ is calculated by the formula
Tn = a + (n - 1) d
Substituting the values in the equation , we get
a₁₀₀ = 7 + ( 100 - 1 ) 6
a₁₀₀ = 7 + ( 99 x 6 )
a₁₀₀ = 7 + 594
The value of a₁₀₀ = 601
Therefore , the figure will have 100 rows of 6 tiles and 1 row having 1 tile
And , the total number of tiles in the figure is 601 tiles
Hence , The figure will have 100 rows of 6 tiles and 1 row having 1 tile and
the number of tiles in figure 100 will be 601 tiles

A rectangular flour canister has dimensions of 512 inches by 4 inches by 10 inches. A smaller sugar canister has dimensions of 312 inches by 3 inches by 8 inches. How much smaller is the volume of the sugar canister than the flour canister?
Answer:
The amount by which the sugar canister is smaller than the flour canister is 136 in³
Step-by-step explanation:
The dimensions of the flour canister = 5 and 1/2 inches by 4 inches by 10 inches
(5 and 1/2 = (5 1/2))
(3 and 1/2 = (3 1/2))
The dimensions of the smaller sugar canister = 3 and 1/2 inches by 3 inches by 8 inches
The volume of the rectangular prism = Length × Width × Height
∴ The volume of the flour canister = (5 1/2) × 4× 10 = 220 in.³
The volume of the sugar canister = (3 1/2) × 3 × 8= 84 in.³
The difference in volume between the flour canister and the sugar canister is given as follows;
220 in.³ - 84 in.³ = 136 in.³
The amount by which the sugar canister is smaller than the flour canister = 136 in.³.

can you draw a triangle with 90 degrees 60 degrees and 60 degrees
Answer:
no
Step-by-step explanation:
the sum of interior angles of a triangle should be 180
so the three possible angles would be 90 degree 60 degree and 30 degree
Answer:
[tex]\huge\boxed{\sf NO.}[/tex]
Step-by-step explanation:
The interior angles of a triangle must be adding to 180 degrees for it to "be" a triangle.
Let's check if 90°,60° and 60° are adding to 180°.
=> 90+60+60
=> 210° > 180°
Since they are not adding to 180°, a triangle with the given angles cannot be formed.

13f + 6 -f = -3
help?
Answer:
f = -3/4
Step-by-step explanation:
13f + 6 -f = -3
Combine like terms
12f +6 = -3
Subtract 6 from each side
12f+6-6 = -3-6
12f = -9
Divide each side by 12
12f/12 = -9/12
f = -3/4
Answer:
f= -3/4 or -0.75
Step-by-step explanation:
We are given the equation:
13f + 6 -f = -3
First, let's combine like terms. Subtract f from 13f.
(13f-f) + 6 = -3
12f + 6= -3
We want to find f. Therefore, we must isolate the variable on one side of the equation.
6 is being added to 12f. The inverse of addition is subtraction. Subtract 6 from both sides of the equation.
12f + 6 -6 = -3-6
12f= -3-6
12f= -9
f is being multiplied by 12. The inverse of multiplication is division. Divide both sides by 12.
12f/12= -9/12
f= -9/12
This fraction can be reduced. Both the numerator and denominator can be divided by 3.
f = (-9/3) / (12/3)
f= -3/4
f=-0.75
The solution to the equation is f= -3/4 or -0.75
What is the range of the function represented by these ordered pairs?
Answer:
B
Step-by-step explanation:
The range of a data set is the y-coordinates of the ordered pairs.
So, we have the ordered pairs:
{(-2,1), (0,0), (3,-1), (-1,7), (5,7)}
So, the range will be (the bolded numbers):
{(-2,1), (0,0), (3,-1), (-1,7), (5,7)}
Thus, our answer is:
{-1, 0, 1, 7}
Note that the range should be in ascending order.
Also note that even though 7 appears twice, 7 is 7, so we only put one 7.
The answer is B.
