Answers

Answer:

When you rub the balloon on your hair, the balloon becomes negatively charged because it gains electrons from your hair.

Step-by-step explanation:

Is it multiple choice? If not the answer is anything positively charged. Negative and positive ions attract, while synonymous (N,N or P,P) repel. Pieces of paper, the wall, or even your clothing are all possibly positive charged objects the balloon could stick to.

An animal shelter has fixed weekly expenses of $750. Each animal in the shelter costs an additional $6 a week. a. During the summer months, the weekly expenses are at least $1170. Write and solve an inequality that represents the number of animals at the shelter for expenses to be at least $1170 a week.​

Answers

Answer:

1170≥6x+750      x=70

Step-by-step explanation:

We can put these numbers into a slope equation, y=mx+b, the fixed weekly expense ($750) represents b. And the $6 per animal is the slope or m. So our equation become y=6x+750. Now the weekly expense is $1170 and will represent the y in the equaion, 1170=6x+750. First subract 750 from both sides, 420=6x, divide by 6 and get that there was 70 animals in the shelter that week.

The number of animals the shelter needs to house in order for expenses to be at least $1170 per week is calculated as 1170≥6x+750 x=70

Explain about the Inequality?

In mathematics, an inequality is a link that compares two numbers or other mathematical expressions unfairly. Size comparisons between two numbers are commonly made on the number line.

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to one another.

These figures can be entered into the slope equation y=mx+b, where the fixed weekly expense ($750) stands in for b. Additionally, the slope or m costs $6 per animal. We now have the equation y=6x+750. The current weekly expense of $1170 will serve as the y-coordinate in the equation, 1170=6x+750. First, divide 750 from both sides by 420 to obtain 6x, then divide that result by 6 to get the number of animals in the shelter that week 70.

Arianna put $250 in a savings account with an interest rate of 3%. If Arianna does not deposit or withdraw any money, what is the amount of interest that Arianna will earn at the end of six MONTHS?

Answers

Answer:

She will earn 485.13075 in interest.

Step-by-step explanation:

Assuming the interest rate is monthly and it is simple interest, the equation is Total = amount * (1 + rate) * time

Fill that out and solve the equation

T = 2500 * (1.03) * 6

T = 2500 * (1.1940523)

T = 2985.13075

To find the interest subtract T by 2500

2985.13075 - 2500 = 485.13075

Use the inequality 12​>6(12x​+2). Complete parts a and b.

Answers

Answer/ Step-by-step explanation:

12>6(12x+2)

Divide both sides by 6. Since 6 is positive, the inequality direction remains the same.

12/6 >12x+2

Divide 12 by 6 to get 2.

2>12x+2

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

12x+2<2

Subtract 2 from both sides.

12x<2−2

Subtract 2 from 2 to get 0.

12x<0

Product of two numbers is <0 if one is >0 and the other is <0. Since 12>0, x must be <0.

x<0

Answer:

Step-by-step explanation:

½(x-2) = 8 + 5x

Multiply both sides by 2

2⋅½(x-2) = 2(8 + 5x)

1(x-2) = 2(8 + 5x)

Apply the distributive rule

x - 2 = 16 + 10x

Subtract x from both sides

-2 = 16 + 9x

Subtract 16 from both sides

-18 = 9x

Divide both sides by the coefficient of x

-18 ÷ 9 = 9x ÷ 9

-2 = x
