A. $1 per box
B. $1.50 per box
C. $2 per box
D. $2.50 per box

Answers

Answer 1
d because 5 divided by 2 is 2.5
Answer 2

The solution is Option D.

The unit rate of the cost per box is given by the equation A = $ 2.50

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The selling price of 2 boxes of cookies = $ 5

So , the cost of 1 box of cookies A = selling price of 2 boxes of cookies / 2

Substituting the values in the equation , we get

Cost of 1 box of cookies A = 5/2

Cost of 1 box of cookies A = $ 2.50

Therefore , the value of A is $ 2.50

Hence , the unit rate of box of cookies is $ 2.50

(22/7-2/3)÷2 is the value of (22/7-2/3)

Answers

22/7 -2/3= 20/4
20/4×1/2=20/8
you need simplifly
so is 4/2

To solve (22/7-2/3)÷2, find a common denominator and simplify within the parentheses, then divide the result by 2, giving the answer of approximately 1.2380952381.

To find the value of (22/7-2/3) divided by 2, you first need to calculate the expression within the parenthesis. You can start by finding a common denominator for 22/7 and 2/3, which is 21. Multiplying the numerator and denominator of 22/7 by 3 and 2/3 by 7 gives you

66/21 - 14/21 = 52/21

Now, you divide this result by 2, which is the same as multiplying by 1/2:

52/21 × 1/2 = 52/42 = 1.2380952381

If you use a calculator for the initial division, you have to ensure that you enter the calculation correctly to avoid errors. For example, using the expression 337/217, when calculated, gives you about 1.5529953917.

Proper use of parentheses is important to avoid mistakes like interpreting the expression as (5.7 x 2.8) / (3.1 x 4.2) instead of 5.7 x (2.8 / 3.1) x (1 / 4.2).

7(y-8)=7y+42 how many solutions does the following equations have

Answers

I don't really understand what you're asking but:
7(y-8) does not equal 7y+42

If you expand 7(y-8), you should get 7y-56

So: 7(y-8)=7y-56
Final answer:

The equation 7(y-8)=7y+42 results in an implausible mathematical statement, meaning it has no valid solutions.

Explanation:

To begin, we isolate variable y in the given equation 7(y-8)=7y+42. First, expand the product on the left-hand side, which will be 7y - 56. This provides the simplified form 7y - 56 = 7y + 42. From this equation, we realize that this is an equation that has no solutions because it results in an implausible statement: -56 is not equal to 42. If we try to solve such an equation, we reduce it to a statement that does not hold true in mathematics, leaving us with no valid solutions for variable y. Therefore, this equation has no solutions.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Nina paid the bill for dinner with her family.

The total cost of the food was $65, and the restaurant added an 8 percent sales tax, $5.20, to the bill.

Then the amount of the bill will be

Bill = Cost of food + Sales tax

Bill = 65 + 5.2

Bill = $70.2

Nina wants to pay a 15 percent tip on the total bill including sales tax.

The amount of the tip of the total bill will be

Tip amount = 15% x $70.5

Tip amount = 0.15 x $70.5

Tip amount = $10.53

The amount of the tip of the total bill will be $10.53.

Then the correct option is C.

A person runs 1 4 of a mile in 1 32 of an hour. Compute the unit rate by setting up a complex fraction and simplifying.

Answers

1/4 mile in 1/32 hr
unit rate would be x miles in 1 hour.
A complex fraction is a fraction that has a fraction in the numerator OR denominator OR both.


(1/4) / (1/32) =(1/4) * (32/1) = 8 miles in 1 hour

Answer:

8 miles per hour

Step-by-step explanation:

Given that a person runs a distance of  1/ 4 of a mile in 1/ 32 of an hour.

We have to compute the unit rate by setting up a complex fraction and simplifying

Let us find distance travelled in one hour.

[tex]\frac{1}{32} hour  .... \frac{1}{4} miles\\1 hour                  ... \frac{1}{4} /\frac{1}{32}\\=\frac{32}{4} =8mph[/tex]

i.e. unit rate is he travels in one hour 8 miles.

Unit rate is normally for a single unit and other unit is left correspondingly

Here hour or time is made as unit i.e. one hour and distance travelled in one hour is calculated as 8 miles per hour.

Answers

Hi , the answer is 915 divided by 7 , that expression doesn't have a two digit quotient.

We need to find which of the expressions does not have a two digit quotient.

The only expression which does not have a two digit quotient is [tex]\dfrac{915}{7}[/tex].

Let us check each expression

[tex]\dfrac{519}{6}[/tex]

Dividing each by three

A motorboat takes 40 minutes to travel 20 miles downstream. The return trip takes 60 minutes. What is the speed of the current?

Answers

The speed of the current is 5 mph and this can be determined by using the concept of upstream and downstream.

Given :

A motorboat takes 40 minutes to travel 20 miles downstream.

When the boat is going downstream current helps the boat and hinders when the boat is going up.

So, the boat downstream speed is given by:

[tex]\rm s = \dfrac{20}{40}=0.5\;miles \;per\;minute=30\;mph[/tex]

The speed of the boat going upstream is:

[tex]\rm s = \dfrac{20}{60}=\dfrac{1}{3}\;miles \;per\;minute = 20\;mph[/tex]

So, the speed of the current adds when the boat is going downstream and subtracted when the boat is going upstream.

Let the speed of the current be 'c' then:

s + c = 30

s = 30 - c     --- (1)

s - c = 20   --- (2)

Substitute the value of 's' inequation (2).

30 - c - c = 20

2c = 10

c = 5 mph

So, the speed of the current is 5 mph.

Perpendicular lines form 90-degree angles, or right angles, to each other on a two-dimensional planeOther real-world examples of perpendicular lines include graph paper, plaid patterns on fabric, square lines of floor tiles, lines of mortar on brick walls, the intersecting lines of a Christian cross, metal rods on the cooking surface of a barbecue grill, wooden beams in the wall of a house, and the designs on country flags such as Norway, the United Kingdom, Switzerland, Greece, Denmark and Finland. Perpendicular lines form the corner of squares and rectangles in various real-world shapes.Perpendicular lines create four right angles at their intersection point, making 360 degrees total. Perpendicular lines also form one angle of a right triangle.

A 2- liter bottle of water has a mass of 2 kilograms. How many grams is that?

Answers

2000 grams. 1 kilogram = 1000 grams

To convert the mass of a 2-liter bottle of water from kilograms to grams, multiply 2 kg by 1000, resulting in 2000 grams.

A 2-liter bottle of water has a mass of 2 kilograms. To convert this mass into grams, we use the fact that 1 kilogram is equal to 1000 grams. Therefore, we perform a simple multiplication:

2 kilograms × 1000 grams/kilogram = 2000 grams.

So, the 2-liter bottle of water has a mass of 2000 grams.
