Answer 1

Answer:

Answer:

C=14

Step-by-step explanation:

To find the minimum value, graph each of the inequalities. After graphing each inequality, test a point and shade the region that satisfies the inequality. Once all inequalities have been shaded, find the region where they all overlap. The region will be bounded by intersection points. Test each of these points into C=x+3y. The least value for C is the minimum.

(14,0) (0,17.5) (3.08,3.64)

C=14+3(0) C=0+3(17.5) C=3.08 + 3(3.64)

C=14 C=52.5 C=14

If the population of an ant hill doubles every 20 days and there are currently 30 ants living in the hill, what will the population be after 60 days?

Answers

The number of ants after 60 days is 240.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The population of ants doubles every 20 days.

Current number of ants = 30

Now,

The number of ants after 20 days.

= 30 x 2

= 60

The number of ants after 40 days.

= 60 x 2

= 120

The number of ants after 60 days.

= 120 x 2

= 240

Thus,

The number of ants is 240.

Jack's mother gave him 50 chocolates to give to his friends at his birthday party. He gave 3 chocolates to each of his friends and still had 2 chocolates left. Write an equation to determine the number of friends (x) at Jack's party.

Answers

Answer:

3x = 48

Step-by-step explanation:

To easily do this, we'll make the statement in mathematical form.

Let x represent the number of friends at Jack's wedding.

The equation would be:

3 * x = 50 - 2

3x = 48

x = 48 / 3

x = 16

Therefore, the equation to determine the number of friends (x) at Jack's party is expressed as:

3x = 48

Two ways you can evaluate 15(90-3)

Answers

15 of 90 minis 3 15 times 90 minus 3

15(90-3)
first way
15 times 90 = 135
15 times 3 = 45
135 - 45 = 90
second way
90-3 = 87
15(87) = 1305

First way is more likely to be correct....

- Mariana debe tomar dos pastillas; una cada 6 horas y otra cada 9 horas. Si a cierta hora toma las dos pastillas juntas, ¿después de cuantas horas volverá a tomarlas simultáneamente?

Answers

Answer:

Mariana takes the two pills together after 18 hours.

Step-by-step explanation:

Mariana must take two pills; one every 6 hours and another every 9 hours.

She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.

To find the time to take the two pills together, take the least common multiple of 6 and 9.

6 = 2 x 3

9 = 3 x 3

So, the least common multiple is 2 x 3 x 3 = 18

So, she takes the two pills together after 18 hours.
