The percentage computed shows that the number of women is 60 while men are 90.

Let the number of women be represented by x.

Since there are are 50% more men than women in the golf club, the number of men will be:

= x + (50% × c)

= x + 0.5x

= 1.5x

Therefore, 1.5x + x = 150

2.5x = 150

x = 150/2.5

x = 60

Number of women = 60

Number of men = 1.5x = 1.5 × 60 = 90

Answer:

D

Step-by-step explanation:

10x² - 25x + 15 = 0

Divide by 5 both sides,

2x² - 5x + 3 = 0

(x - 1) (2x - 3) = 0

Factors: x - 1 and 2x - 3

Answer: D

Answer:

32

Step-by-step explanation:

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

Given n(A)= ? we represent with x

n(B)= 16

n(A∪B) = 32

Substituting in equation 1 to get n(A)

32  = n(A) + 9 − 9

⇒n(A) = 32 − 0

n(A)  = 32

to confirm this we put the values into the formula below

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

32 =  32 + 9 - 9

Answer:

  n(A) = 25

Step-by-step explanation:

The relation between cardinality of two sets and that of their union and intersection is ...

  n(A∪B) = n(A) +n(B) -n(A∩B)

  32 = n(A) +16 -9 . . . . . use the given information

  25 = n(A) . . . . . . . . . subtract 7

We can write the two given inequalities as:

0 < x < 1/3

And the graph of it can be seen below.

Here we want to graph the inequalities:

x < 1/3

x > 0.

To do it, we can rewrite the inequality as:

0 < x < 1/3.

To graph this, we need to work with a number line. First, we will mark both of the ends of the inequality, that is x = 0 and x = 1/3, both will be graphed with open circles, which means that these points are not solutions. Then, we need to shade the region between these points.

The graph can be seen below.

Answer:

4.95/1.1 = 4.5 approximately 5 bags

Answer:

1.085 metres

Step-by-step explanation:

1 cm = 0.01 m

8.5 cm = 0.085 m

1m+0.085m=1.085 metres

Answer:

1.085 metres

Step-by-step explanation:

100 centimetres = 1m

what about 8.5 cm?

Divide the centimetres by 100

8.5/100 = 0.085m

Then add the metre(s) you already have which is 1

thus 0.085 + 1

1.085m

Answer:

[tex]6*\frac{32}{8}+7[/tex]

Step-by-step explanation:

The required expression, six times the quotient of thirty-two and

eight, increased by seven, is given as x = 6(32/8) + 7.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the expression equal to x,
According to the question,
Six times the quotient of thirty-two = 6(32 /8)
Increased by seven = 6(32 /8) + 7
X = 6(32 /8) + 7

Thus, the required expression, six times the quotient of thirty-two and

eight, increased by seven, is given as x = 6(32/8) + 7.

Answer:

  application of L'Hopital's rule to the presumed indeterminate form yields this conclusion

Step-by-step explanation:

This is a reverse application of L'Hopital's rule for determining the limits involving indeterminate forms.

When the expression evaluated at the limit is 0/0, then L'Hopital's rule tells you the limit can be found from n'/d', where n and d are the numerator and denominator of the original expression, respectively.

We can see that x-π = 0 at x=π, so we assume that f(π) = 0 as well, and the expression n/d = f(x)/(x-π) evaluates to the indeterminate form 0/0.

The derivatives are ...

  n' = f'(x)

  d' = 1

Then we have the limit as ...

  lim{x→π) = n'/d' = f'(π)/1 = 3   ⇒   f'(π) = 3

The conclusion f(π)=0 and f'(π)=3 follows from L'Hopital's Rule.
