Answer:
98
Step-by-step explanation:
7 : 11 :: x : 154
Also,
[tex] \frac{7}{11} = \frac{x}{154} [/tex]
[tex] = > \frac{x}{154} = \frac{7}{11} [/tex]
[tex] = > x = \frac{7 \times 154}{11} [/tex]
=> x = 7 × 14
=> x = 98 (Ans)

The diagram below shows the contents of a jar from which you select marbles at random.
An illustration of a jar of marbles is shown. Four of the marbles are labeled with an upper R, seven of the marbles are labeled with an upper B, and five of the marbles are labeled with an upper G. The key identifies upper R to represent red marbles, upper B to represent blue marbles, and upper G to represent green marbles.
What is the probability of selecting a red marble, replacing it, and then selecting a blue marble? Show your work.
What is the probability of selecting a red marble, setting it aside, and then selecting a blue marble? Show your work.
Are the answers to parts (a) and (b) the same? Why or why not?
Answer:
A:
probability of red = 4/16 = 1/4
prob(blue) = 7/16
probability of red, then blue is (1/4)(7/16) = 7/64
B:
probability red = 1/4
probability blue = 7/15
probability of red, then blue = (1/4)(7/15) = 7/60
c) your decision
Step-by-step explanation:
i took the test
The solution is,
A. 7/64 is the probability of selecting a red marble, replacing it, and then selecting a blue marble.
B. 7/60 is the probability of selecting a red marble, setting it aside, and then selecting a blue marble.
C. the answer is no.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given,
There are 4 red marbles.
There are 7 blue marbles.
There are 5 green marbles.
There are 16 marbles in total.
A:
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
probability of red = 4/16 = 1/4
probability(blue) = 7/16
probability of red, then blue is (1/4)(7/16) = 7/64
B:
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
probability red = 1/4
probability blue = 7/15
probability of red, then blue = (1/4)(7/15) = 7/60
c) obviously,
7/64 ≠ 7/60
So the answer is no.

quadrilateral vwxy with vertices v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6): 18o from the origin
Given:
The vertices of a quadrilateral are v(-2,-1) w(-5,-2) x(-8,-7) and y(1,-6).
To find:
The vertices of the image of quadrilateral vwxy after 180° about the origin.
Solution:
If a figure rotated 180° about the origin, then the rule of rotation is
[tex](x,y)\to (-x,-y)[/tex]
Using this rule, we get
[tex]v(-2,-1)\to v'(2,1)[/tex]
[tex]w(-5,-2)\to w'(5,2)[/tex]
[tex]x(-8,-7)\to x'(8,7)[/tex]
[tex]y(1,-6)\to y'(-1,6)[/tex]
Therefore, the vertices of image of quadrilateral vwxy after 180° about the origin are v'(2,1), w'(5,2), x'(8,7), y'(-1,6).

Simplify. Your answer should contain only positive exponents.
Answer:
[tex]\frac{1}{4k^3}[/tex]
Step-by-step explanation:
It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as [tex]k*(4k^{4})^{-1}[/tex] or [tex]k*4^{-1}*k^{-4}[/tex] The question asks for positive exponents though so yu don't need to do that.
You also need to know [tex]\frac{x^a}{x^b}=x^{a-b}[/tex] so in this case [tex]\frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}[/tex]
so [tex]\frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}[/tex]

If the sum of the measures of the interior angles of a polygon is 1920°, how many sides does it have? math
Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Step-by-step explanation:
The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-
[tex](n-2)\times180^{\circ}[/tex]
Given: The sum of the measures of the interior angles of a polygon is 1920°.
i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]
[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]
But number of sides cannot be in decimal.
Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
During a 40% off sale, Tessa pays $24 for a sled. What was the original price?
Answer:
$33.6
Step-by-step explanation:
24*1.4=33.6
the 1.4 represents the added 40% to find the original price of the sled
Answer:
original price = 40
Step-by-step explanation:
make an equation using the information given in the question, x will represent the original price
x - 0.4x = 24
or
x - 2/5x = 24
solve for x
x - 2/5x = 24
3/5x = 24
x = 40

Answers provided below
Step-by-step explanation:
From the simultaneous linear equation, we have the coefficient matrix as;
(3 4 5)
(2 -1 8)
(5 -2 7)
The x-matrix is Dx is given by;
(18 4 5)
(13 -1 8)
(20 -2 7)
Similarly, the y-matrix Dy is given by;
(3 18 5)
(2 13 8)
(5 -20 7)
Also,the z-matrix Dz is given by;
(3 4 18)
(2 -1 13)
(5 -2 -20)
Determinant of the coefficient matrix from online determinant calculator is;
D = 136
Determinant of the x-matrix from online determinant calculator is; Dx = 92
Determinant of the y-matrix from online determinant calculator is; Dy = 696
Determinant of the z-matrix from online determinant calculator is; Dz = 576
From crammers rule;
x = Dx/D = 92/136
y = Dy/D = 696/136
z = Dz/D = 576/136

[tex]\huge\boxed{\sf 18 cm\²}[/tex]
Step-by-step explanation:
The figure consists of 2 rectangles.
Rectangle 1 Area:
Length = 5 cm
Width = 2 cm
Area = Length * Width
A = 5 * 2
A = 10 cm²
Rectangle 2 Area:
Length = 4 cm
Width = 2 cm
Area = 2 * 4
A = 8 cm²
Area of the whole figure:
= Rectangle 1 + Rectangle 2

what is the solution of the system equation?
y=3x+7
y=x-9
Answer:
y=-17, x=-8
Step-by-step explanation:
x-9=3x+7
Isolate x for x-9=3x+7;
x-9=3x+7
Add 9 to both sides:
x-9+9=3x+7+9
Simplify;
x=3x+16
Subtract 3x from both sides;
x-3x=3x+16-3x
Simplify;
-2x=16
Divide both sides by -2;
-2x/-2=16/-2
simplify: -2x/-2
=x
Simplify 16/-2:
x=-8
For y=x-9 substitute x=-8;
y=-8-9
Simplify;
y=-17
The solutions to the System of equations are;
y=-17, x=-8
