Answer: 84 tickets

Step-by-step explanation:

We are told the ratio of the number of tickets Mark collected to the number of tickets Julia collected is 4:3

\frac{M}{J}=\frac{4}{3} (1)

In addition, we are told Julia collected 36 tickets:

J=36 (2)

Substituting (2) in (1):

\frac{M}{36}=\frac{4}{3} (3)

Isolating M:

M=48 (4)

Adding Mark's tickets to Julia's:

M+J=48+36=84

Therefore, both collected 84 tickets.

Jacob is a plumber. Due to increased material costs, he puts all his prices up by 7%. He now chargers R320 per hour for her serv
Lorico [155]

Answer:

R290.1

Step-by-step explanation:

Let

x = charge before he put his prices up

New charge = R320

Percentage increase in price = 7%

x + 7% of x = 320

x + 0.07 * x = 320

x + 0.07x = 320

1.07x = 320

x = 320/1.07

x = 299.06542056074

Approximately

x = R290.1

Charge before he put his prices up = R290.1

Hope is the coach of the Wilson High School girls' soccer team. There are 3 minutes left in the game they are currently playing,
NISA [10]

To answer this question, we need to find the winning probability in either case.

Probability = no. of outcomes / total no. of possible outcomes

<u>When Hope pulled her defender :</u>

Total no. of games = 9

No. of games won = 3

Winning probability = 3/9 =1/3

<u>When Hope left her defender :</u>

Total no. of games = 10

No. of games won = 6

Winning probability = 6/10 = 3/5

We know that , 1/3 < 3/5.

So, Hope should not pull her defender, as the winning probability is better when Hope left her defender.

Answer : A. Hope should not pull her defender.

Bruce wants to make 50 ml of an alcohol solution with a 12% concentration. He has a 10% alcohol solution and a 15% alcohol solut
Inessa05 [86]

The equation is 0.1x + 0.15(50-x)=1.20(50)

Step-by-step explanation:

Here you need 50ml of 12% alcohol solution.

You have 10% and 15% alcohol solutions.

Take volume of 10% alcohol solution to be x ml

Take volume of 15% alcohol solution to be y ml

Form equations;

x+y=50 ml--------------------------equation 1

0.1x +0.15 y= 12% of 50

0.1x+0.15y=6-----------------------equation 2

Now you have simultaneous equations, use a graph tool to solve for values of x and y as attached.

or use the mixture equation the get value of x

0.1x + 0.15(50-x)=1.20(50)

The values of x and y are ;

(x,y) (30,20) which means;

y is 20 ml of 15% alcohol

x is 30 ml of 10% alcohol
