Area of rectangle = 408 in²
Length = 3x-2 and width = x
The area of a rectangle is given by :
A = lb
(3x-2)x = 408
x = 12 inch and x = -11.33 in
Neglecting negative value,
The width of rectangle = 12 inch
The length of rectangle = 3x-2 = 3(12)-2 = 34 inch

Base of triangle = 2x+2
Height = x
The area of a triangle is given by :
[tex]A=\dfrac{1}{2}bh\\\\600=\dfrac{1}{2}\times (2x+2)x\\\\600=(x+1)x[/tex]
x = 24 cm and x = -25 cm
Neglecting negative value, x = 24 cm
Base = 2x+2 = 2(24)+2 = 50 cm
Hence, this is the required solution.
There is a 75% chance Matt will choose pepperoni pizza and a 1/3 chance Ashley will choose a salad. Assuming they are independent events, what is the probability Matt will choose pepperoni pizza and Ashley will choose a salad? Write your answer as a percentage.
Answer:0
Step-by-step explanation:
0
The probability Matt will choose pepperoni pizza and Ashley will choose a salad is 1/4.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
There is a 75% chance Matt will choose pepperoni pizza
= 75/ 100
= 3/4
and, Ashley chooses a salad which had a chance = 1/3.
As, the events are independent then we know that if two events A and B are independent evets then
P(a B)= P(A) . P(B).
so, the probability is
= 1/3 x 3/4
= 1/4

Out of 18 people in a room, 2 have red hair. What is the probability that a person picked at random from the room does NOT have red hair?
Give an explanation plz:)
Answer :
Total number of people in the room = 18Number of people with red hair = 2Number of people not with red hair = 18 - 2 = 16Probability of picking a person who doesn't have red hair = [tex]\sf\dfrac{Number\:of\:favourable\:outcomes}{Total\:outcomes}[/tex]Probability = 16/18
Reduce the fraction with 2
Probability = 8/9
Answer:
[tex]\implies\boxed{\red{\sf P( not \ having\ red\ hair)=\dfrac{ 8}{9}}}[/tex]
Step-by-step explanation:
Given :-
There are 18 people in the room .Two of them have Red hair.And we need to find the probability that a person picked at random from the room does not have red hair . So for that firstly let us find how many people do not have red hair.
According to Question :-
[tex]\implies n_{(red)}+ n_{(not\ red)}= 18 \\\\\implies 2 + n_{(not\ red)}= 18 \\\\\implies n_{(not\ red)}= 18 -2 =\boxed{\red{16}}[/tex]
Hence the probability is :-
[tex]\implies P( not \ having\ red\ hair)=\dfrac{ n_{(favourable\ outcomes)}}{n_{(possible\ outcomes)}} \\\\\implies P( not \ having\ red\ hair)=\dfrac{ 16}{18} \\\\\implies\boxed{P( not \ having\ red\ hair)=\dfrac{ 8}{9}}[/tex]
Hence the required probability is 8/9 .

Answer:
3) 522
4) 468
Step-by-step explanation:
hello!
3) in the question, it says the cross section is a square, and the area of PQRS is 81.
for the square, we know that the length and height have to be the same, so if the area is 81, then we know the sides are both 9 because 9*9 is 81 and they're the same numbers multiplied. (same height and length)
with the information that all 4 sides of the square is 9 and the other side is labeled 10, we can figure out the rest.
both squares : 81+81=162
both 10 by 9 sides: 90+90=180
both 10 by 9 sides (top and bottom): 90+90=180
total surface area=162+180+180=522
4) for this problem, we can see that the triangle is a right triangle.
to solve the area of the triangle, we can do (9*12)/2=108/2=54.
there are two sides with triangles, so we double 54 (54*2=108)
9 by 10 side: 90
10 by 12 side: 120
now for the last slide, theres no information on the length. the formula for the diagonal is
a^2+b^2=c^2
which is
9^2+12^2=81+144=255=15^2
with this, the area of the rectangular side gives us 10*15 which is 150.
adding it together, we get
108+90+120+150=468.
hope this helps!

, arc RS = 86
, and RU is tangent to the circle at R. Find mZU.
S
U
Answer:
[tex]\angle U = 20^\circ[/tex]
Step-by-step explanation:
Given
See attachment
[tex]\angle S = 23[/tex]
arc [tex]RS = 86[/tex]
Required
Find [tex]\angle U[/tex]
Let
[tex]O \to[/tex] center of the circle
We have that:
arc [tex]RS = 86[/tex]
This implies that:
[tex]\angle SOR = 86^\circ[/tex]
and
[tex]\triangle SOR \to[/tex] is an isosceles triangle
because:
[tex]SO = OR \to[/tex] the radius of the circle
And
[tex]\angle RSO = \angle ORS[/tex]
So, we have:
[tex]\angle RSO + \angle ORS + \angle SOR = 180^\circ[/tex] --- angles in a triangle
[tex]\angle RSO + \angle ORS + 86^\circ = 180^\circ[/tex]
Collect like terms
[tex]\angle RSO + \angle ORS =- 86^\circ + 180^\circ[/tex]
[tex]\angle RSO + \angle ORS =94^\circ[/tex]
Recall that: [tex]\angle RSO = \angle ORS[/tex]
So:
[tex]\angle RSO + \angle RSO =94^\circ[/tex]
[tex]2\angle RSO =94^\circ[/tex]
Divide by 2
[tex]\angle RSO =47^\circ[/tex]
RU is a tangent.
So:
[tex]\angle ORU = 90^\circ[/tex]
Given that:
[tex]\angle S = 23[/tex]
Considering [tex]\triangle SRU[/tex]
We have:
[tex]\angle RSU = \angle S = 23^\circ[/tex]
So:
[tex]\angle SRU= \angle RSO + \angle ORU[/tex]
[tex]\angle SRU= 47 + 90[/tex]
[tex]\angle SRU= 137[/tex]
Lastly:
[tex]\angle RUS + \angle RSU + \angle SRU =180^{0}[/tex]
[tex]\angle RUS + 23 + 137=180^{0}[/tex]
Collect like terms
[tex]\angle RUS =180^{0} - 23 - 137[/tex]
[tex]\angle RUS =20^{0}[/tex]
Hence:
[tex]\angle U = 20^\circ[/tex]

If two points known on the line A B in the coordinate plane is (7,15) and (18,42), calculate the slope of the line AB and the length of the line AB
Answer:
Slope = 27/11
AB = 29.15 u
Step-by-step explanation:
Given :-
Two points are given to us .The points are A(7,15) and B(18,42)To Find :-
The slope of the line .The length of line AB .We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,
[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]
Plug in the respective values ,[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]
Hence the slope of the line is 27/11 .
[tex]\rule{200}2[/tex]
Finding the length of AB :-
We can find the distance between them by using the Distance Formula .[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]
Hence the length of AB is 29.15 units .

In the diagram, PQRS is a rectangular sloping surface, PQTU is a rectangle on horizontal ground and RI and
SU are vertical lines. PQ = SR=UT = 45 cm, QR = PS = 32 cm and angle RQT= 38º.
Calculate
PR,
(b) RT, and
(c) angle RPT
Answer:
(a) PR = 55.2 cm
(b) RT = 19.7 cm
(c) <RPT = [tex]20.8^{o}[/tex]
Step-by-step explanation:
(a) to determine the value of PR, apply the Pythagoras theorem to PQR.
PQ = 45, and SP = QR = 32. So that;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]/PR/^{2}[/tex] = [tex]45^{2}[/tex] + [tex]32^{2}[/tex]
= 2025 + 1024
= 3049
PR = [tex]\sqrt{3049}[/tex]
= 55.218
PR = 55.2 cm
(b) To determine RT, apply the appropriate trigonometric function to QRT.
Let RT be represented by x, so that;
Sin [tex]38^{o}[/tex] = [tex]\frac{x}{32}[/tex]
x = 32 * Sin [tex]38^{o}[/tex]
= 32 * 0.6157
x = 19.7024
RT = 19.7 cm
(c) To determine <RPT, let the angle be represented by θ.
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
= [tex]\frac{RT}{PR}[/tex]
Sin θ = [tex]\frac{19.7024}{55.218}[/tex]
= 0.3568
θ = [tex]Sin^{-1}[/tex] 0.35568
= [tex]20.84^{o}[/tex]
Thus, <RPT = [tex]20.8^{o}[/tex]

The wavelength of a certain type of light is 0.0000014 inches. Write the wavelength in scientific notation.
Answer: [tex]1.4\times 10^{-6}[/tex]
Step-by-step explanation:
Given
The wavelength of light is 0.0000014 inches
Here, seven digits are followed by a decimal point
To convert it to scientific notation, convert it into a fraction i.e.
[tex]=0.0000014=\dfrac{14}{10,000,000}[/tex]
In the denominator, there are 7 zeroes
[tex]\therefore 0.0000014=\dfrac{14}{10^7}\\\\\Rightarrow 0.0000014=14\times 10^{-7}\\\\\Rightarrow 0.0000014=1.4\times 10^{-6}[/tex]

The last math exam of the year was normally distributed with a mean of 85 and a standard deviation of 5. Xavier needed at least a 95 on this test to get an A for the year. His teacher gave him his z-score: 1.8. Did Xavier get an A for the year?
Answer:
Xavier did not get an A for the year.
Step-by-step explanation:
We solve this question using z score formula
= z = (x-μ)/σ, where
x is the raw score = ?
μ is the population mean = 85
σ is the population standard deviation = 5
z = 1.8
Hence
1.8 = x - 85/5
Cross Multiply
1.8 × 5 = x - .5
9 = x - 85
Collect like terms
9 + 85 = x
x = 94
Xavier scored 94.
He needs at least 95 to get an A.
Therefore, we can conclude that Xavier did not get an A for the year.
