Answer:
4 sqrt(3) = x
Step-by-step explanation:
We have similar triangles
The ratios of the sides have to be in proportion
The large triangle has sides x and hypotenuse 12
The small triangle has side 4 and hypotenuse x
We can write the ratio of sides to hypotenuse
x 4
---- = -------
12 x
Using cross products
12*4 = x^2
48 = x^2
Taking the square root
sqrt(48) = sqrt(x^2)
sqrt(3*16) = x
sqrt(16) sqrt(3) = x
4 sqrt(3) = x
Hello,
y=10x+175
y=-x²+50x
==> x²+10x-50x+175=0
==>x²-40x+175=0
==>x²-5x-35x+175=0
==>x(x-5)-35(x-5)=0
==>(x-5)(x-35)=0
==> x=5 or x=35
Answer: A AND C.
The state of the market if market price was fixed at Birr 25 per unit is excess demand
<h3>Quantity demanded</h3>
Qd = 50 - p
p = Qs + 5
p - 5 = Qs
if market price was fixed at Birr 25 per unit?
Qd = 50 - p
= 50 - 25
Qd = 25
Qs = p - 5
= 25 - 5
Qs = 20
The state of the market if market price was fixed at Birr 25 per unit is excess demand (demand greater than supply) leading to an increase in price.

Answer:
<h3>a) 3/4</h3><h3>b) 4:3</h3>
Step-by-step explanation:
Find the diagram attached.
Given the scale factor of circle A to circle B as 3/4
A:B = 3:4
Total ratio = 3+4 = 7
Area of bigger square A = 45sq. units;
The Total area can be gotten using the expression;
where;
x is the total area of both circles.
Get x;
Area of circle B = 78.75 - 45 = 33.75
Let the fraction required be y
45 * y = 33.75
y = 33.75/45
y = 3375/4500
y = 45/60
y = 3/4
Hence the area of circle B is 45 * <u>3/4</u> of circle A
b)The ratio of circle A to Circle B is expressed as;
Ratio = Area of circle A/Area of circle B
Ratio = 45/33.75
Ratio = 45 * 100/3375
ratio = 4500/3375
Ratio = 4:3
Hence the ratio of circle A to Circle B is 4:3
