Yes, because if you divide 4 and 3 by 2, you get 2 and 1.5
X + y = 90 ; x - y = 14
x = 52
y = 38
52 + 38 = 90
52 - 38 = 14
Answer:
9,948,394.
Step-by-step explanation:
Here, the other races is 4% of the total population. So we calculate 4/100 * 248,709,873=9,948,394.92. If you can't have a fractional amount of people is would be 9,948,394.
We are given the area of a circle and we are asked to find its diameter. To do that, we need to remember the formula for the area of a circle:
Now we solve for the diameter "D". First by multiplying both sides of the equation by 4
Now we divide by pi
Now we take square root on both sides:
Simplifying:
Replacing the value for the area:
Simplifying:
When we simplify (3 + √5)(3 + √2), the result obtained is:
9 + 3√2 + 3√5 + √10
<h3>Surd operation </h3>
a√b × c√d = (a × c)√(b × d)
<h3>How to simplify (3 + √5)(3 + √2)</h3>
(3 + √5)(3 + √2)
Expand by clearing the bracket
3(3 + √2) + √5(3 + √2)
9 + 3√2 + 3√5 + √10
Thus,
(3 + √5)(3 + √2) = 9 + 3√2 + 3√5 + √10
