Answer:
x = 111 degrees
Step-by-step explanation:
the angle next to 164 degrees :
any line = 180 degrees, so 180 - 164 = 16 degrees
now you have two out of three angles in the triangle. All three angles of every triangle must add together to equal 180, so
180 = 53 + 16 + x
or
x= 180 - 53 - 16
x=111 degrees

The shape is composed of squares and quarter circles. Select all the expressions that represent its perimeter. (Select all that apply.) 42+14 7+7+7+7+7+7+3.5+3.5+3.5+3.5 91+14 147+49 7+7+7+7+7+7+7+7+7+7
Answer:
91+14π
Step-by-step explanation:
The question is incomplete. Find the complete question attached.
From the diagram shown;
It contains 4 quarter circles which is equal to a circle.
Perimeter of a circle = 2πr
r is the radius = length of one side of the square =7
Perimeter of the circle = 2πr
Perimeter of the circle = 2π(7)
Perimeter of the 4 quarter circles = 14π
Also in the diagram, there are 13 sides of the square present.
Perimeter of the squares = 13×length of one side of the square (Sum of all the sides)
Perimeter of the squares = 13×7 =91
Perimeter of the figure = Perimeter of the 4 quarter circles + Perimeter of the squares
Perimeter of the figure = 91+14π

The height of a triangle is 7 cm and the height of a similar triangle is 21 cm. How much larger is the
area of the larger triangle?
Answer:I'm pretty sure the ratio is 3:1
Step-by-step explanation:
find the value of x and y
x° + 2y° = 180° ⇒ 2y° = 180° - x°
x° = 60° {three sides of the same lengh, means three angles=60°}
2y° = 180° - 60°
2y° = 120°
y° = 60°

A study by Great Southern Home Insurance revealed that none of the stolen goods were recovered by the homeowners in 80 percent of reported thefts: [ 6 marks] a. During a period in which 200 thefts occurred, what is the probability that no stolen goods were recovered in 170 or more of the robberies? b. During a period in which 299 thefts occurred, what is the probability that no stolen goods were recovered in 150 or more robberies?
Solution :
Given :
n = 200, p = 80% = 0.8, q = 1 - p = 0.2
[tex]$\mu = np$[/tex]
[tex]$= 200 \times 0.8 = 160$[/tex]
[tex]$\sigma= \sqrt{npq}$[/tex]
[tex]$\sigma= \sqrt{200 \times 0.8 \times 0.2}$[/tex]
= 5.6569
a). x = 169.5
∴ [tex]$z = \frac{x- \mu}{\sigma}$[/tex]
[tex]$z = \frac{169.5- 160}{5.6569}$[/tex]
= 1.6794
[tex]$P(x \geq 170) = P(z>1.6794) = 0.0465$[/tex]
Therefore, probability that the stolen goods were not recovered in 170 robberies or more is = 0.0465
b). x= 149.5
[tex]$z = \frac{x- \mu}{\sigma}$[/tex]
[tex]$z = \frac{149.5- 160}{5.6569} = -1.8561$[/tex]
[tex]$P(x \geq 150) = P(z>-1.8561) = 0.9683$[/tex]
Therefore the probability that the stolen goods were not recovered in the 150 or in more robberies is = 0.9683

line e has a slope of -2/9. line f is perpendicular to e. what is the slope of f
Answer:
9/2
Step-by-step explanation:
In order to find the slope of a line that is perpendicular to another line, you must find the opposite and reciprocal of that slope. So, you have 2/9, and then 9/2.
Answer:
slope of f = [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{2}{9} }[/tex] = [tex]\frac{9}{2}[/tex]
Write the equation, in slope-intercept form, of the line that passes through (-2,0) and is parallel to the line represented by 5x-3y=-17 .
Answer:
[tex]y=\frac{5}{3}x+\frac{10}{3}[/tex]
Step-by-step explanation:
Firstly we rewrite the equation that is parallel to the line we need because parallel lines have the same slope by the rule
[tex]m_1=m_2[/tex]
so we rewrite the equation in slope-intercept form:
[tex]5x-3y=17\\-3y=-5x+17\\y=\frac{-5x+17}{-3}\\\\y=\frac{-5x}{-3}+\frac{17}{-3} \\\\y=\frac{5}{3}x-\frac{17}{3}[/tex]
and now we compare it with our slope-intercept form equation:
[tex]y=mx+b[/tex]
the coefficient of x which is m is the slope and since parallel lines have equal slopes the line that we need would also have the same slope which is 5/3.
now the next step is the line that we need passes through the point (-2,0) so it means that it should satisfy that specific point so we insert that point into our slope-intercept form and insert the slope which is 5/3 which is m.
[tex]y=mx+b\\y=\frac{5}{3}x+b\\\\0=\frac{5}{3}(-2)+b\\\\0=\frac{-10}{3}+b\\\\b=\frac{10}{3}\\[/tex]
now we know that the y-intercept(b) of the line we need is 10/3 and slope(m) is 5/3 insert these values into our slope-intercept form:
[tex]y=mx+b\\y=\frac{5}{3}x+\frac{10}{3} \\[/tex]
so this is our given line.

A fraction becomes 4÷5 if 1 is added to both numerator and denominator. If, however, 5 is subtracted from both numerator and denominator , the fraction becomes 1÷2. Find tge fraction by using crammer rule.
Answer:
[tex]\dfrac{7}{9}[/tex]
Step-by-step explanation:
[tex]\dfrac{x+1}{y+1}=\dfrac{4}{5}\\\Rightarrow 5x-4y=-1[/tex]
[tex]\dfrac{x-5}{y-5}=\dfrac{1}{2}\\\Rightarrow 2x-y=5[/tex]
Putting it in matrix form
[tex]\begin{bmatrix}a_{1}&b_{1}\\a_{2}&b_{2}\end{bmatrix}{\begin{bmatrix}x\\y\end{bmatrix}=\begin{bmatrix}{c_{1}}\\{c_{2}}\end{bmatrix}\\\Rightarrow\begin{bmatrix}5 & -4\\2 & -1\end{bmatrix}\begin{bmatrix}x\\ y\end{bmatrix}=\begin{bmatrix}-1\\ 5\end{bmatrix}[/tex]
From Cramer's rule we have
[tex]x=\dfrac{\begin{vmatrix}c_1 &b_1 \\ c_2 & b_2\end{vmatrix}}{\begin{vmatrix}a_1 &b_1 \\ a_2& b_2\end{vmatrix}}\\\Rightarrow x=\dfrac{\begin{vmatrix}-1 &-4 \\ 5 & -1\end{vmatrix}}{\begin{vmatrix}5 &-4 \\ 2& -1\end{vmatrix}}\\\Rightarrow x=\dfrac{1+20}{-5+8}\\\Rightarrow x=7[/tex]
[tex]y=\dfrac{\begin{vmatrix}a_1 &c_1 \\ a_2 & c_1\end{vmatrix}}{\begin{vmatrix}a_1 &b_1 \\ a_2& b_2\end{vmatrix}}\\\Rightarrow y=\dfrac{\begin{vmatrix}5 &-1 \\ 2 & 5\end{vmatrix}}{\begin{vmatrix}5 &-4 \\ 2& -1 \end{vmatrix}}\\\Rightarrow y=\dfrac{25+2}{-5+8}\\\Rightarrow y=9[/tex]
Verifying the results
[tex]\dfrac{7+1}{9+1}=\dfrac{8}{10}=\dfrac{4}{5}[/tex]
[tex]\dfrac{7-5}{9-5}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]
Hence, the fraction is [tex]\dfrac{7}{9}[/tex].

Step-by-step explanation:
How do we find the line that's perpendicular to another?
We find the negative reciprocal. So for example if our slope is 2, the negative reciprocal would be [tex]- \frac{1}{2}[/tex].
A racing car travels at a speed of 193 miles per hour.
Work out an estimate for the number of seconds the racing car travels in 10 miles.
Answer:
The estimate is 186.5 seconds.
Step-by-step explanation:
To calculate the estimate of the time the racing car will take to travel 10 miles, we have to first find the ratio of the original distance to the requested distance.
The number of seconds in an hour is [tex]60 \cdot 60[/tex] seconds, which equals to 3600 seconds.
[tex]\frac{193}{10} = \frac{3600}{x}[/tex]
[tex]19.3 = \frac{3600}{x}[/tex]
[tex]x = \frac{3600}{19.3}[/tex]
[tex]x \approx 186.5[/tex]
Hence, the estimate is 186.5 seconds.

3×-5=16 and 3×=21
the first equation is a true statement for a certain value of x.
can you explain why the second equation must also be true for the same value of x?
Step-by-step explanation:
because we can also find out the value of x in second equation like this
3x=21
x=21/3
x=7
Answer:
We conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.
Step-by-step explanation:
Given the first equation
3x-5 = 16solving the equation
3x-5 = 16
adding 5 to both sides
3x-5+5 = 16+5
3x = 21 ∵ 3x = 21 is the 2nd equation
divide bothe sides by 3
3x/3 = 21/3
x = 7
Please notice that when simplifying 3x-5 = 16, the moment we reach 3x=21, we can determine that it represents the same equation.
In other words, whatever the value of x we will get, it will satisfy both equations.
Therefore, we conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.
Verification:
Consider the 2nd equation
3x = 21
Put x = 7
3(7) = 21
21 = 21
Thus, it has been validated that when we conclude that x = 7 must be true for the second equation because it will also satisfy the second equation.
(2+3i)(1-2i)
What is the product of the complex number
Answer:
(2+3i)(1-2i) = (8-i)
Step-by-step explanation:
The given complex number is :
Z = (2+3i)(1-2i)
We need to find the product of the complex number
[tex]Z=2(1)+2(-2i)+3i(1)-6i^2\\\\=2-4i+3i-6i^2[/tex]
We know that, [tex]i^2=-1[/tex]
[tex]Z=2-i-6(-1)\\\\=2-i+6\\\\=8-i[/tex]
Hence, the product of the complex number is (8-i).
