Step-by-step explanation:
Let H = HCF(A,B) and L = LCM(A,B)
Then A*B = L*H
Here L*H = 100*5 = 500
Also H <= A ,B <= L
So we need to find all A*B = 500, satisfying the above condition. This can be done using prime factorisation of 500.
Here 500 = 2^2 * 5^3
so possible values of A and B are
1 , 500
2, 250
4, 125
5,100
10,50
20,25
(assuming order doesn’t matter.)
so pairs satisfying given condition are → (20,25) and (100,5)
You can write a computer program in language of your choice to do it for other bigger numbers.

Answer:
A = 15x^2 +11x+4
Step-by-step explanation:
can we assume you want the area...
A = 1/2 (B1+B2) h
A = 1/2(10x +4)(3x+2)
A= 1/2(30x^2 +22x+8)
A = 15x^2 +11x+4

If 1 is added in numerator and denominator then a fraction changes to 4. If 1 is subtracted from the numerator and denominator, fraction changes to 7. Numerator of the fraction is
Answer:
N=15
Step-by-step explanation:
N=numerator
D=denominator
(1+N)/(1+D)=4
(N-1)/(D-1)=7
(1+N)=4(1+D)
N=4D+3
(4D+3-1)/(D-1)=7
4D+2=7(D-1)
4D-7D=-2-7
D=-9/-3=3
N=4D+3=15

Given a right triangle ABC with altitude BD drawn to hypotenuse AC. If AC = 24 and DC = 6, what is the length of BC?
Answer:
BC = 12Step-by-step explanation:
BD is the altitude, it breaks ΔABC into two similar triangles:
ΔABD ~ ΔBCDThe ratios of corresponding sides:
AD/BD = BD/DC ⇒ BD² = AD*DC ⇒ BD² = (24 - 6)*6 ⇒ BD² = 108On the other hand:
BC² = BD² + DC² ⇒ BC² = 108 + 6² = 144 BC = √144BC = 12
What are the lengths of AD, DB, AE, and EC? Measure and record them.
If the abscissa of a point is negative , then in which all quadrants the point can lies?
Answer:
The point can either lie on the second quadrant or the third quadrant
Step-by-step explanation:
Mathematically, we have the ordinate and the abscissa
The ordinate represents the y axis while the abscissa represents the x axis value
For the abscissa to be negative, it means we are talking about the negative x axis
Now, the y axis can either be positive or negative too
When it is positive , we are referring to the point lying on the second quadrant
when it is negative, we are referring to the point lying on the third quadrant
She has 40 coins all made up of quarters and dimes, And when she counted them up she had $7.75 from them, how much of each did she have?
Answer:
x = number of quarters = 25
y = number of dimes = 15
Step-by-step explanation:
Let
x = number of quarters
y = number of dimes
1 dime = $0.10
1 quarter = $0.25
x + y = 40 (1)
0.25x + 0.10y = 7.75 (2)
From (1)
x = 40 - y
Substitute x = 40 - y into (2)
0.25x + 0.10y = 7.75 (2)
0.25(40 - y) + 0.10y = 7.75
10 - 0.25y + 0.10y = 7.75
- 0.25y + 0.10y = 7.75 - 10
-0.15y = -2.25
y = -2.25/-0.15
y = 15
Substitute y = 15 into (1)
x + y = 40 (1)
x + 15 = 40
x = 40 - 15
x = 25
x = number of quarters = 25
y = number of dimes = 15
Total quarters = 25 × $0.25
= $6.25
Total dimes = 15 × $0.10
= $1.5

: Cho tam giác ABC vuông tại C, trong đó AC = 0,9m, BC = 1,2m. Tính các tỉ số lượng giác của góc B, từ đó suy ra các tỉ số lượng giác của góc A.
Answer:
Step-by-step explanation:
Vì tam giác ABC vuông tại C nên ta áp dụng định lí pitago=> AB²=AC²+BC²=0.9²+1.5²=3.06=>AB= (3 căn bậc hai của 34)/10
sin B=AC/AB=(3 căn bậc hai của 34)/34
cos B=BC/AB
tan B= AC/BC
cot B= BC/AC
Tương tự suy ra tỉ số lượng giác góc A

x+7=2(x-15) solve for x
Answer:
x = 37
Step-by-step explanation:
x+7 = 2(x-15)
x+7 = 2x-(2*15)
x+7 = 2x-30
7+30 = 2x-x
37 = x
So, the answer is x = 37.

Terms/CoefficientsSolving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
2x - y = 11
x + 3y = -5
Step 2: Rewrite Systems
2x - y = 11
[Subtraction Property of Equality] Subtract 2x on both sides: -y = 11 - 2x[Division Property of Equality] Divide -1 on both sides: y = 2x - 11Step 3: Redefine Systems
y = 2x - 11
x + 3y = -5
Step 2: Solve for x
Substitution
Substitute in y [2nd Equation]: x + 3(2x - 11) = -5[Distributive Property] Distribute 3: x + 6x - 33 = -5Combine like terms: 7x - 33 = -5[Addition Property of Equality] Add 33 on both sides: 7x = 28[Division Property of Equality] Divide 7 on both sides: x = 4Answer:
x = 4
Step-by-step explanation:
2x - y = 11
x + 3y = -5
To calculate the value of x , firstly we need to find value of y.
solve for y
2x - y = 11subtract 2x from both side
2x - 2x - y = 11 - 2x-y = 11 - 2xchange the sign of both side of equation
y = -11 + 2xrewrite
y = 2x - 11Solve for x
y = 2x - 11x + 3y = -5substitute the value of y in the equation
x + 3( 2x - 11 ) = -5distribute 3
x + 3 × 2x - 3× 11 = -5x + 6x - 33 = -5combine like terms
7x - 33 = -5Add 33 on both side
7x - 33 + 33 = -5 + 337x = 28divide both side by 7
7x / 7 = 28 / 7x = 4Argent deadline is tomorrow a²-(b-c)²

Aisha wants to paint the four walls of her living room. Each wall is 2.6 m high and 3.5 m long. One wall has a door of 2.2 m by 0.8 m. Tins of paint cost £11 per 2 L tin. Each litre of paint can cover 8 m2 of wall. There is an offer of: Buy 2 tins get the 3rd at half price. How much will Aisha pay to paint her living room
Answer:
£22
Step-by-step explanation:
Area to be painted
4walls - door
a = 4(2.6 * 3.5) - 2.2 * 0.8
a = 34.64 m²
Paint needed
p = 34.64 / 8
p = 4.33
Must round up
p = 5 liters
Tins needed
t = 5/2
t = 2.5
must round up
t = 3
Cost
since 1 is free with 2 will pay for 2
c = 11 * 2
c = 22

Step-by-step explanation:
We are finding the discriminant
b^2 -4ac
2x^2 - 2x - 1 = 0
a =2 b = -2 c = -1
(-2)^2 - 4(2)(-1)

Answer:
[tex]b^2 - 4ac= 12[/tex]
Step-by-step explanation:
Standard quadratic equation :
[tex]ax^2 + bx + c = 0[/tex]
Given equation :
[tex]2x^2 - 2x - 1 = 0[/tex]
From the given equation , a = 2, b = -2 , c = -1
Therefore,
[tex]b^2 - 4ac= ( -2)^2 - ( 4 \times 2 \times (-1))[/tex]

find the vaule of a in ax+by=c
Answer:
a=[tex]\frac{c-by}{x}[/tex]
Step-by-step explanation:
To find a, we need to change the equation so a is the variable that is left by itself. So...
ax+by=c Get rid of anything else besides the x and its coefficient.
-by -by
ax=c-by Because a has to be completely isolated, get rid of its coefficient.
/x /x
a=[tex]\frac{c-by}{x}[/tex]
Hope this helps and have a great day :D
Answer:
[tex]a x + by = c \\ ax = c - by \\ \frac{ax}{x} = \frac{c - by}{x} \\ a = \frac{c - by}{x}[/tex]
Which statements about this system of equations are true? Check all that apply. Negative x + 6 y = 16. 8 x minus 6 y = negative 2.
Step-by-step explanation:
The given equations are :
-x+6y = 16 ...(1)
8x-6y = -2 ...(2)
The y-variable will be eliminated when adding the system of equations.
Adding equations (1) and (2).
-x+6y+8x-6y = 16+(-2)
7x = 14
x = 2
Put the value of x in equation (1).
-2+6y = 16
6y = 16+2
y = 3
There is only one solution to the system of equations i.e. (2,3).
