Answer:
The answer is (0)15
Step-by-step explanation:
The ratio of the integer is stated to be as (0)15.
Answer:
Find the value of x, if 8,x, x, 50 are in proportion.
If a,b,c and d are in proportion then we have a/b = c/d
Now we need to find the value of x given if 8, x, x, 50 are in proportion.
So we have 8/x = x/50
Or x x x = 8 x 50
Or x^2 = 400
Or x = ±√400
Or x = ± 20
Therefore the value of x will be + 20 or - 20

Answer:
Ivan gets £90 more than Tanya
Step-by-step explanation:
Given that
Total amount = £150
Ratio: 4:1

Now,
Ivan's Share:
Tanya's Share:
Ivan gets £120 and Tanya gets £30
The difference between their shares is the answer.
So,
Hence,
Ivan gets £90 more than Tanya
Answer:
<BAC = 20°
Step-by-step explanation:
It is given in the question that all 9 triangle which are formed are congruent, which means that in all triangles, the angle which is formed at point A is same.
Which means 9 angles collectively can be written as 9 · <BAC
If we consider all the 9 triangles, we can see in the figure that it forms a semicircle.
A semicircle has a total sum of angles equal to 180°
So we can write that:
9 · <BAC = 180°
Simplify for <BAC
<BAC = 20°
