100-20=80%=400
[tex]\\ \rm\longmapsto 80\%\:of\:CP=400[/tex]
[tex]\\ \rm\longmapsto CP=400\times \dfrac{100}{80}[/tex]
[tex]\\ \rm\longmapsto CP=5(100)[/tex]
[tex]\\ \rm\longmapsto CP=500[/tex]
Step-by-step explanation:
Given,
S.p.=Rs400
Loss percent(L%) =20%
C.p.=?
We know,
S.p. =(100-L) % of c.p.
or,400=(100-20)% *c.p.
or,400=80% *c.p.
or, 400=80/100*c.p.
or,c.p.=Rs.500
Here, c.p.=Rs.500

17. What is the sum of 1/9, 2/3, and 5/18?
O A. 4/15
O B. 12/g
O C. 8/30
O D.
19/18
MA .

AL HADIR
Answer: D 19/18
Step-by-step explanation: First you have to make a common denominator of 18. 1/9 becomes 2/18. 2/3 becomes 12/18. 5/18 stays the same. Then you have to add the numerators and you get 19/18.
Side XY is of length 11b .
Side XZ is of length 2a+3b.
Side YZ is of length a The triangle is isosceles, with XY=XZ
The perimeter of the triangle is 91. Use algebra to find the values of a and b.
Answer:
a = 14, b = 3.5
Step-by-step explanation:
XZ = XY , then
2a + 3b = 11b ( subtract 3b from both sides )
2a = 8b ( divide both sides by 2 )
a = 4b
The perimeter is 91 , so
11b +2a + 3b + a = 91
14b + 3a = 91 ← substitute a = 4b
14b + 3(4b) = 91
14b + 12b = 91
26b = 91 ( divide both sides by 26 )
b = 3.5
and a = 4b = 4 × 3.5 = 14

[tex] {x}^{2} {y}^{8} [/tex] (second option)
Step-by-step explanation:
[tex] \frac{( {x}^{2} {y}^{3} {)}^{4} }{( {x}^{3} {y}^{2} {)}^{2} } [/tex]
[tex]( {x}^{2} {y}^{3} {)}^{4} = ( {x}^{2} {)}^{4} \times ( {y}^{3} {)}^{4} [/tex]

The sum of the present ages of a son and his father is 60 years. Six years ago, father's
age was five times the age of the son. After 6 years, what will be son's age?
Answer:
15 years old
Step-by-step explanation:
The equation for their present ages is s+f=60. Six years ago would make it 54 and since the father's age six years ago was 5 times his son's the equation would be s+5s=54 (add the common terms) 6s=54. 54/6 is 9. So the son's age is 9, currently. In six years, the kid will be 15.

Qu. In a triangle ABC, side AB has length 10cm, side AC has length 5cm, and angle BAC = θ
where θ is measured in degrees. The area of triangle ABC is 15cm^2
(a) Find the two possible values of cos θ
Given that BC is the longest side of the triangle,
(b) find the exact length of BC.
Answer:
To find cosθ, use the formula for the area of a triangle i.e. AREA=1/2 x a x b x sinC.=> For this case: 15= 1/2 x 10 x 5 x sinC to find sinC.=> SinC = 3/5 thus, Arcsin(3/5)=+- 4/5 or +-0.8
To find the exact length of BC, use the cosine rule.=> c(sq)=a(sq)+b(sq)-2abCosC=> c(sq)=10(sq)+5(sq)-2(10)(5)(+-4/5)=> c(sq)= Square root of 205

Three friends all live on the same street that runs west to east. Ben lives 7 blocks from Al. Carl lives 4 blocks from Ben. If the street is represented by a number line and Al's house is located at 0, what are the possible locations for Carl's house?
Answer:
Carl is located in 11
Step-by-step explanation:
I. If the street runs west to east
AI is 0
Ben is -7
Carl is -11
But there's no negative in address in the real world
so Cars is located in 11

(1 point) Find the equation of the line that contains the point (8,6) and is perpendicular to the line 3x + 2y = 2. Write
the equation in the form y = mx + b and identify m and b.
Step-by-step explanation:
Equation of given line:
3x+2y=2
2y=-3x+2
y=-3/2 x +2
slope =m1=-3/2
As lines are perpendicular:
m1×m2=-1
-3/2×m2=-1
required slope=m2=2/3
By using point slope form:
y-6=2/3(x-8)
3y-18=2x-16
3y=2x-16+18
3y=2x+2
y=2/3 x+2
m=2/3 ,b=2

determine is true Given a right triangle with side lengths of 4, 5, and 3, if we increase the length of the hypotenuse by 2 units but decrease the length of each leg by 1 unit, then the resulting triangle is still a right triangle.
9514 1404 393
Answer:
False
Step-by-step explanation:
The new side lengths are 3-1 = 2 and 4-1 = 3. The new longest side is 5+2 = 7.
The side lengths 2, 3, 7 do not form any sort of triangle, much less a right triangle.
The statement is false.
