x^2/3=12
Plz I need help with this ASAP, it’s solving quadratic functions by square roots by the way
Answers
Answer:
this is easy. all you have to do is multiply the denominator (3) by the outside number (12) to get 36. this leaves the equation being x^2 = 36. now you just find the square route of 36 (which is 6).
Step-by-step explanation:
x^2/3 = 12
12 x 3 = 36
x^2 = 36
/36 = 6
x = 6

Answers
Answer:
Area of rectangle= 24 × 7 = 168
Area of trapezium = ((a+b)/2)h = 74
Total area = 168 + 74 = 242
Answer:
242in^2
Step-by-step explanation:
Area of parallelogram is
1/2(a+b)×h
a=13in
b=24in
h=4in
= 1/2(13+24)×4
=1/2(37)×4
so the area of the parallelogram is
=74in^2
Area of rectangle is
L×B
L=24in
B=7in
=24×7
=168in^2
so the area will be the sum of the area of parallelogram and rectangle
=74in^2+ 168in^2
=242in^2

List the first three wholenumbers greater than 50 that will have a remainder of 7 when you divide by 9/ ?
Answers
Answer:
52, 61 and 70
Step-by-step explanation:
Given
[tex]Divisor = 9[/tex]
[tex]Remainder = 7[/tex]
Required
Determine first 3 possible dividends
The relationship between the [tex]dividend,\ divisor,\ quotient\ and\ remainder[/tex] is:
[tex]Dividend = Divisor * Quotient + Remainder[/tex]
Substitute: [tex]Divisor = 9[/tex] and [tex]Remainder = 7[/tex]
[tex]Dividend = 9* Quotient + 7[/tex]
Since the Dividends must be greater than 50, then the values of the quotient will be 5, 6 and 7
So, we have:
[tex]Dividend = 9* 5 + 7 = 45 + 7 = 52[/tex]
[tex]Dividend = 9* 6 + 7 = 54 + 7 = 61[/tex]
[tex]Dividend = 9* 7 + 7 = 63 + 7 = 70[/tex]
Hence, the three numbers are: 52, 61 and 70

width is represented by 3x + 7. The perimeter of the rectangle is 35 units.
Find the value of x
Answers
Answer:
x = 1.5
Step-by-step explanation:
The perimeter of a rectangle is calculated by adding widht and height and multiply it by 2
The lenght is 2x + 3 and the width is 3x + 7
(2x + 3 + 3x + 7) *2 = 10x + 20 this is the perimeter which is given as 35 units
10x + 20 = 35 subtract 20 from both sides
10x = 15 divide both sides by 10
x = 1.5

Pls help as I'm preparing for my exams
Answers
Answer:
Hope this helps you..
Brainliest plsssss
All the Best for your exams
Step-by-step explanation:
let the breadth=x
the length =x+15
given perimeter= 150
Perimeter of rectangle = 2x(l+b)
150 = 2( x+ x+15)
75 = 2x +15
60 = 2x
30=x
therefore breadth = 30 cm
length = 30 +15 = 45 cm
Verification:
150 = 2( 45+30)
150 = 2(75)
150 = 150
LHS=RHS
Hence, proved..
Answer:
Step-by-step explanation:
Let the breadth(b) be x . Then by the question
Length (L) = ( x + 15 )cm
Perimeter = 150 cm
or 2( L + b) = 150
2 ( x + 15 + x ) = 150
2x + 15 = 75
2x = 75 - 15
2x = 60
x = 30 cm
Therefore breadth or width is 30 cm
Similarly
Length = 30 + 15 = 45

(a) What is 0.36 as 36 repeating expressed as a fraction in simplest form?
(b) What is 0.36 as 6 repeating expressed as a fraction in simplest form?
(c) What is 0.36 expressed as a fraction in simplest form?
Answers
Answer:
Step-by-step explanation:
A.the fraction is technically 36/99, but simplified version is 4/11
X = 0.36363636......
100x = 36.363636.....
100x - x =36.363636 - 0.363636....
99x=36
X=36/99
= 4/11
0.36363636363 is the first repeating fraction and 36.36363636 is the second repeating fraction, because you multiply it by 100.
b.0.3666 ... = 11/ 30
Explanation:
x = 0.3666 . .
(1) 10 x = 3.666 ...
(2) 100 x = 36.666 ...
(2)-(1):
100 x − 10 x = 36.666 ... − 3.666 ...
90 x = 33
x = 33/ 90 = 11/ 30
c.9/25
0.36 in the simplest form as fraction is 9/25.

hello :
A game is played with the following rules. Three ordinary coins are flipped and count as a single "turn" in the game.
Each coin could land on heads or tails. After their turn a player is given a certain number of points depending on the
outcome.
•If the result is 3 heads, the player receives +4 points.
• If the result is 2 heads, the player receives +2 points.
• If the result is anything else, the player receives -1 point.
What is the expected value of the number of points a player will receive after a turn?
Answers
=======================================================
Explanation:
H = heads
T = tails
Something like HHT means we get two heads in a row at first, followed by one tail. The order matters. Since there are 2 sides per coin, and 3 coins, this leads to 2^3 = 8 different possible ways to flip three coins.
Those 8 outcomes are:
HHHHHTHTHHTTTHHTHTTTHTTTAgain the order matters.
------------
Now let's define the following events
A = event of getting three headsB = event of getting exactly two headsC = event of getting 1 head, or getting 0 headsThere's only one way to get three heads, and that's HHH. So P(A) = 1/8.
There are three ways to get exactly two heads. Those three ways are: HHT, HTH, THH. This means P(B) = 3/8.
From those two probabilities, we then know that P(C) = 4/8 = 1/2 since there are 1+3 = 4 ways to get two or more heads, leaving 8-4 = 4 ways to get the other situations.
Now let's define function notation V(A) to mean "the net value of event A occurring". It's the number of points you receive if event A happens. We are given the following info:
V(A) = 4V(B) = 2V(C) = -1From here, multiply the probability values with their corresponding net values
P(A)*V(A) = (1/8)*(4) = 0.5P(B)*V(B) = (3/8)*(2) = 0.75P(C)*V(C) = (1/2)*(-1) = -0.5Finally, add up those results to get the expected value: 0.5+0.75+(-0.5) = 0.75
Each time a turn happens, we expect on average to get 0.75 points
Imagine a scenario where you play the game 10,000 times. If you record the result of each turn and then compute the arithmetic mean, you should get somewhere close to 0.75; it likely wont be 0.75 exactly due to the nature of theoretical probability and empirical probability not being perfectly aligned. However, due to the law of large numbers, the two should be very close when you do a large number of trials.
Because we're dealing with averages, it is possible to get a decimal value as the answer even though the point values of events A,B,C are integers.

What is the arc measure, in degrees, of ADC on circle P below?
70°
104°
Answers
Answer:
The answer is "[tex]\overarc{ADC} = m\angle CPD + m\angle DPA = 186[/tex]"
Step-by-step explanation:
Please find the image of the question:
In the circle p:
[tex]\to m\angle APB + m\angle BPC + m\angle CPD + m\angle DPA = 360^{\circ} \\\\\to 70 + 104 + m\angle CPD + m\angle DPA = 360\\\\\to m\angle CPD + m\angle DPA = 360 - 70 - 104 = 186[/tex]
Let P is in the center
[tex]\to[/tex] arc AD= [tex]m\angle APD[/tex]
[tex]\to[/tex] arc DC = [tex]m\angle CPD[/tex]
[tex]\to[/tex] arc BC = [tex]m\angle BPC[/tex]
arc AB =
When D is on arc AC:
[tex]\to[/tex]arc ADC = arc AD + arc DC
[tex]\to[/tex]arc ADC = [tex]m \angle CPD + m\angle DPA = 186[/tex]
