15 - 1 (12/4 + 1) =
Please explain your answer.

Answers

Answer:

The Answer here is 11

Step-by-step explanation:

First, we divide inside the parentheses because we always do what is inside the parentheses first, and division comes before addition. So 12/4 is 3. Next we add 3 plus 1, which is 4. Then we multiply (Because multiplication comes before subtraction, and parentheses mean multiplication) 4 times 1 which is 4. Then we subtract 15-4 which comes out to 11.

Hence the answer here is 11.

Ms. Romero runs a house cleaning business. To save money, she bought a 1-gallon container of concentrated cleaner. She mixed the cleaner with 10 gallons of water. Then, she filled as many 1-pint spray bottles as she could. How many spray bottles did she fill?

Answers

i think the answer should be 6 bottles.

Answer:

88 Spray bottles

Step-by-step explanation:

You need to find how many spray bottles Ms. Romero filled. But first, you need to know how much cleaning solution she had in all.

Ms. Romero mixed 1 gallon of concentrated cleaner with 10 gallons of water. So, she had 11 gallons of cleaning solution in all.

Ms. Romero filled each spray bottle with 1 pint of cleaning solution. So, find how many pints are in 11 gallons. There are 2 pints in a quart, and there are 4 quarts in a gallon. That means there are 8 pints in a gallon, so multiply 11 gallons by 8.

11×8=88

Ms. Romero had 88 pints of cleaning solution. Since she filled each spray bottle with 1 pint, she filled 88 spray bottles.

Does the size of a circular object affect the relationship between its circumference and its diameter?

A. The size will affect the relationship between circumference and diameter because of circumference changes at a greater rate than the diameter.

B. The size has no effect on the relationship between circumference and diameter because the ratio is always equal to

C. The size has no effect on the relationship between circumference and diameter because the two values change independently.

D. The size will affect the relationship between circumference and diameter because of the value changes as the circumference changes.

Answers

Answer: A

Step-by-step explanation: It doesn't. The circumference of a circle is 2*pi*radius and the diameter is 2*radius, so the circumference divided by the diameter is pi, which is the ratio of circumference to diameter.

Mr. Santos treated his students to a movie for winning the state contest. This also required taking some of the students’ parents as chaperones. The movie theatre charges $4 for each student and $6 for each adult. If Mr. Santos spent $180 on movie tickets and took 40 people (including himself), how many students did he take to the movies.

write two equations to help find the answer

Answers

Answer: 41

Step-by-step explanation:

Using a system of equations, it is found that he took 30 students to the movies.

------------------------------

This question is solved using a system of equations, and I will say that:

x is the number of students taken.y is the number of adults taken.

------------------------------

40 people were taken, and thus:

[tex]x + y = 40[/tex]

As we want the number of students x, we can represent y as function of x, thus:

[tex]y = 40 - x[/tex]

------------------------------

Each student costs $4.Each adult costs $6.The total amount spent was $180.

Thus:

[tex]4x + 6y = 180[/tex]

Since [tex]y = 40 - x[/tex]

[tex]4x + 6(40 - x) = 180[/tex]

[tex]4x + 240 - 6x = 180[/tex]

[tex]-2x = -60[/tex]

[tex]2x = 60[/tex]

[tex]x = \frac{60}{2}[/tex]

[tex]x = 30[/tex]

He took 30 students to the movies.

2.5 = 0 - (-20)
0-17.5
0-22.5
O 22.5
0 17.5

Answers

Answer:

Step-by-step explanation:Simplifying

0 = 2.5y + -20

Reorder the terms:

0 = -20 + 2.5y

Solving

0 = -20 + 2.5y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2.5y' to each side of the equation.

0 + -2.5y = -20 + 2.5y + -2.5y

Remove the zero:

-2.5y = -20 + 2.5y + -2.5y

Combine like terms: 2.5y + -2.5y = 0.0

-2.5y = -20 + 0.0

-2.5y = -20

Divide each side by '-2.5'.

y = 8

Simplifying

y = 8

SO the answer is y=8 I think srry if i get it wrong
