Answer: 4051 girls, 4862 boys and 1570 adults over 50 years of age group attended the festival.
Step-by-step explanation:
Let x denotes the number of girls.
Then, the number of boys = x+811
The number of adults over 50 years of age = x-2481
Now, by considering the given scenario :-
Thus, the number of girls attended the festival = 4051,
Then number of boys = 4051+811=4862
Number of adults = 4051-2481=1570
Answer:
7
Step-by-step explanation:
You can convert the fourth square roots to 
. Using the product of powers rule, we can add the four terms' exponents, resulting in 
, which is 7.
Refer to the diagram shown below.
Let the distance that Sassoon travels is d miles.
Let his average speed be x mph.
The time of travel is from 1 p.m. to 4 p.m., which is 3 hours.
Therefore
3x = d (1)
The distance that Archer travels is (d + 300) miles.
The time of travel is from 9 a.m. to 4 p.m., which is 7 hours.
The average traveling speed is (x + 20) mph, therefore
7(x + 20) = d + 300
That is,
7x + 140 = d + 300
7x = d + 160 (2)
Subtract (1) from (2).
7x - 3x = d + 160 - d
4x = 160
x = 40 mph (Sassoon's average speed)
x+20 = 60 mph (Archer's average speed)
From (1), obtain d = 120 mi
Answer:
Archer's speed is 60 mph.
Sassoon's speed is 40 mph.
First take the product 2 times 32 is 64 because there are only two numbers the nth root is the square root, and the square root of 64 is 8. Therefore geometric mean of 2 and 32 is 8
2x^2(x+2) +6(x+2) = (2x^2 +6)(x+2) = 2(x^2 +3)(x+2)
so this mean that the 4th choice will be right sure
