slavikrds [6]3 years ago

Answer:

x=18

y=24

Step-by-step explanation:

Let the number of boys in the camp = x

Number of girls = y

\frac{x}{y}=\frac{3}{4}\\x=\frac{3y}{4} -----(A)

Total number of students = 42

x+y=42

Putting value of x from A

\frac{3y}{4}+y=42\\\frac{3y+4y}{4}=42\\\frac{7y}{4}=42\\y=\frac{42 \times 4}{7}\\y=24

Putting this value in A and solving for x

x=\frac{3 \times 24}{4}\\x=18

The weight of an object on the moon varies directly with its weight on the earth. If an object weighing 95 lbs on the moon weigh
Luda [366]
ANSWER

450lb

EXPLANATION

If the weight, m of an object on the moon varies directly as the weight of an object e, on the earth, then we can write the mathematical statement,.
m \propto \: e
We introduce the constant of proportionality to obtain,

m = ke

When, m=95, e=570,

This implies that,

95 = 570k
k = \frac{95}{570}

k = \frac{1}{6}

The equation now becomes,

m = \frac{1}{6} e

We want to find e, when m=2700,

m = \frac{1}{6} \times 2700

m =450lb

Answer:

13. Answer: 0

17. Answer: 3

19. Answer: 2

Step-by-step explanation:

13. f(g(3))

First find g(3) on the right graph.

We see that at x = 3, g(x) = 4

So g(3) = 4

Next find f(g(3)). Since g(3) = 4, that means we have to find f(4) and the from the left graph we see that f(4) = 0 answer

17.f(f(5))

f(5) = 1

f(f(5)) = f(1) = 3 answer

19. g(g(2))

g(2) = 0

g(g(2)) = g(0) = 2 answer
