Elijah has 4 new dogs and wants to build a square fence in his backyard for them. He wants the sides to each measure (x + 6) feet. Which expression below would he use to find the perimeter of the fence?

Answers

4(x+6)
Perimeter = the sum of all the sides.
Square has equal length for all its only 4 sides
Therefore if one side is x+6
Then it is 4 times x+6

A. Sarah's bill at the restaurant was $12.81. She left a tip of 20%. What was the tip amount? Round your answer to the nearest hundredth.
B. What was the total bill? Round your answer to the nearest hundredth.

Answers

Answer:

A. $2.56

B. $15.37

Step-by-step explanation:

A. When you’re asking what is a certain percent of a specific number, you turn the percent into a decimal and multiply it by the specific number. In this case, 0.20 * 12.81 = 2.562

Since we are to round to the nearest hundred, that leaves us with $2.56.

B. To get the total bill, add 12.81 and 2.56 to get a total of $15.37.

A : 2.56 reason: 12.81 x 1/5 is 2.56
B add them together you get 15.37
you round them to hundredths

Jim started cleaning at :1009 AM and finished at :1132 AM.
How long did it take him?

Answers

Answer:

1 hour and 23 minutes

Step-by-step explanation:

11:32-10:09=1:23

Thinking through this logically, one hour after 10:09 is 11:09 and we know that it took him longer than this.

We can then subtract the minutes without having to worry about the base-60.  

32 minutes -9 minutes =23 minutes

We then add the 23 minutes to the 1 hour and determine that it took him 1:23 (one hour and twenty-three minutes).

The length and width of a square is 9.5 inches (for both) what is the area and perimeter?

Answers

Answer:

90.25, 38

Step-by-step explanation:

The area is the two sides multiplied against each other, so 9.5*9.5

Since it's a square all of the sides are 9.5 inches, so just multiply 9.5 times 4 for the perimeter

Area is 90.25 and perimeter is 38

-32xy-25 try dat anyways have a nice dayyyy byeeeee

Step-by-step explanation:

i believe what you need help on is simplifying the equations. so let's start with the first one.

====================================================================

(2x+1)(x+5) original problem

(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.

2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.

2x2+11x+5 this is the most simplified equation.

====================================================================

6x−4xy original problem.

unlike the last problem, we can easily just... 6x + (−4xy).

−4xy+6x this is the most simplified equation.

====================================================================

ok, the last one. phew!

unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.

if we factored, we would get...

(4x+5)(4x−5)

===================================================================

the serving size for a toddlers daily vitamin c is 3/4 cup of orange juice. if there are 2 1/4
cups of orange juice how many servings of vitamin c are there for a toddler

Answers

Three servings
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings

Answer:

Three servings

To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .

2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4

1. 4.5*10 so that is the cost of snacks for the 10 skaters
2. 1.5*10 so that is the cost of skates for the 10 skaters
3. Finally the flat rate of 250 will stay the same no matter the number of skaters
