Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.

A cinema has three screens . last saturday there were 500 visitor . 40% went to screen 1 . 25% went to screen 2. The rest went t

Butoxors [25]

Answer:

Screen 1: 200, Screen 2: 125 , Screen 3: 175

Step-by-step explanation:

Screen 1

Multiply 40% and 500

Convert 40% to a decimal

40/100=0.40

500*0.40

200

Screen 2

Multiply 25% and 500

Convert 25% to a decimal

25/100=0.25

500*0.25

125

Screen 3

Subtract the amount of people that went to screens 1 and 2 from the total

500-200-125

175

So, Screen 1 had 200 visitors, 2 had 125 and 3 had 175

Hope this helps! :)

A horse race has 13 entries and one person owns 5 of those horses. Assuming that there are no ties, what is the probability tha

statuscvo [17]

Answer:

0.000777

Step-by-step explanation:

The number of possibilities that the 5 horses can finish in the first 5 spots is given by the permutation of those five horses in the first five positions:

$n = \frac{5!}{(5-5)!}\\ n=5*4*3*2*1\\n=120\ ways$

The number of possible outcomes for the first 5 places is given by the permutation of 13 horses in the first five positions:

$N = \frac{13!}{(13-5)!}\\ N=13*12*11*10*9\\N=154,440\ ways$

The probability that those five horses finish first, second, third, fourth and fifth is:

$P=\frac{120}{154,440}\\ P=0.000777$

Z is inversely proportional to A and if Z=225 when A = 15 find an equation connecting Z and A and the value of A when Z = 75

Wewaii [24]

Answer:

equation connecting them: Z = k 1/A

k being the constant

225 = K * 1/15

K * 1/15 = 225 (flip to solve more easily)

k = 3375

Z = k * 1/A

75 = 3375 * 1/A

75 = 3375/A

A = 45
