Answer: B

Step-by-step explanation:

the cost is $8, and it goes for 40% off, so the discount is 8*40%=3.2;

then the sale price = 8-3.2 = 4.8.

Answer: B

Explanation:
To find the discount, you have to multiply the percentage, 40%, by the usual cost, $8.00.

$8.00 x .4 = $3.20

Now to find the sales price, subtract your discount amount from the original price.

$8.00 - $3.20 = $4.80

x > 5.4
One-half less-than x

Answers

An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:

x > 5.4

One-half less-than x

x > 0

All of the options that are just LESS THAN are open circled

if an inequality states less than OR equal to that means the circle will be closed when graphed

pls help me

Answers

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 120 milligrams of Medication A with 132 milligrams of Medication B. However this week, the doctor said to only use 121 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?

Answers

Answer: 109 milligrams of Medication A.

Explanation: If last week was 132 milligrams of Medication B and 120 milligrams of Medication A. Then Medication B has is 12 milligram more then Medication A. So you would do 121 milligrams minus 12 milligrams to get Medication A for this week.

The teachers have $25 to buy supplies . Write and evaluate a numerical expression to show how much more money they will need to buy the cups and napkins.

Cups= $3.50 -12 per package
Napkins= $4.25 - 10 per package

Answers

Answer:

they will need 25 dollars more to buy the cups n napkins

The  expression for the remaining money required by the teachers is 25 - 3.5x - 4.25y.

What is an Algebraic expression?

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

Given that,

The total amount of money the teachers have is $25.

The rate of cups per package is $3.50.

And, the rate of napkin per package is $4.25.

Suppose the number of packages of cups and napkins be x and y respectively.

Then, the expression for the money required to buy them is given as follows,

25 - (3.5x + 4.25y)

= 25 - 3.5x - 4.25x

Hence, the expression for the remaining amount of money required to buy cups and napkins is 25 - 3.5x - 4.25y.

Answer:

150 votes were casted

Step-by-step explanation:

So first, we know that Amy received 48 votes. Then Neil received 1/4 as many votes as Amy. So we can divide 48 by 4:

48/4=12

Neil got 12 votes. We also know that Neil and Amy's votes together is only 40% of the votes casted in total. So we can add their votes together and then find a fifth of the votes casted by dividing the 40% in half:

12+48=60

60/2=30

So now 30 votes are 20% of the total votes casted, now we just have to multiply by 5:

30*5=150

A girl is half as old as her sister and is also two years younger than her brother. If the sum of the three children's ages is 34 years, what is the product of their ages?
ASAP pls

Answers

Answer:

1280

Step-by-step explanation:

Let x represent the age of the girl then...

Brother: x+2

Sister: 2x

We can use this to set up an equation:

x+x+2+2x=34

Combine like terms

4x+2=34

Subtract 2 from both sides

4x=32

Divide both sides by 4

x=8 (girl)

x+2=10 (brother)

2x=16 (sister)

Now, we multiply these three numbers to get the product of their ages.

8(10)(16)=80(16)=1280

Evander would like to buy a new hockey stick. He earns $15 time he cuts the grass in his neighborhood. Because of his busy schedule, he can cut grass on Saturdays and Sundays. Evander is responsible for paying $10/week toward his cell phone bill. He also enjoys chocolate and has a $2 bar least twice weekly. Every time he cuts two lawns, he has to fill up the lawnmower with $5 worth of gas.

If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?




Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?




When could Evander save enough for the stick if he stopped eating chocolate bars?





When could Evander save enough for the stick if he was able to cut another lawn on Wednesday nights AND stopped eating chocolate?

Answers

Answer/Step-by-step explanation:

If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?

earns - 30  pays - $10pb $2b  $5(this is for the 2 days)

SO he gets 30 but spends 19,

Meaning he gets $11 proffit.

30-19 =  $11

Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?

He makes $11 every week. so 229.99/11 = 20.9, so it will take him 21 weeks to get it.

When could Evander save enough for the stick if he stopped eating chocolate bars?

Ok so he would be getting 2 dollars more so that would make it $13. So 229.99/13 = 17.69, meaning it will take 18 weeks to get it.

Given that, the equations that have {4} as its solution set.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

1) Solution of an equation 5 + 2x = 3x + 3 is

3x-2x=5-3

⇒x=2

2) Solution of an equation 7−x=12x is

7−x=12x

⇒12x+x=7

⇒13x=7

⇒x=7/13

3) Solution of an equation 79−3x=12x+19 is

12x+3x=79-19

⇒15x=60

⇒x=4

4) Solution of an equation x²+3=10x−21 is

x²+3=10x−21

⇒ x²-10x+24=0

⇒ x²-6x-4x+24=0

⇒ x(x-6)-4(x-6)=0

⇒ (x-6)(x-4)=0

⇒ x=6 or 4

Find 250% of 18. Show your work or explain how you arrived at your answer.
Please keep the explanation simple

Answers

Answer: 45

100% of 18 = 18

50% of 18 = 9

18 + 18 = 36 = 200%

36 + 9 = 45 = 250%

:)

Answer: 45

Step-by-step explanation:

To find a percentage of a number, like what we're being asked to do, you multiply the number ( 18 in this case ) with the decimal form of the percentage. So, since we know 100% is equal to 1, 150% is equal to 1.5 and so on, 250% must be equal to 2.5. Since we know this, we now do:

2.5 x 18 = 45.
