Brandon has a total of $3.28 consisting of an equal number of pennies nickels dimes and quarters.How many coins does he have in all? What strategy would be best to solve this problem

Answer:

The first, second, and fourth questions.

Step-by-step explanation:

None of these result in an answer of 23, so I'm assuming that you meant 2/3.

"Two gallons of water are needed to fill 3 fish tanks of equal size. How many gallons of water are required for each tank?"

2 gallons divided between 3 tanks is 2 divided by 3, so 2/3.

"Three cats share 2 cans of tuna. How much of a can does each cat receive?"

2 cans divided between 3 cats - it's the same as the above problem, just with cats and tuna cans instead of tanks and gallons of water. Each cat gets 2/3 of a can.

"Two bags of bird seed are split among 5 parrots. What fraction of a bag does each parrot receive?"

2 bags divided between 5 parrots would be 2/5 of a bag for each parrot.

"Two apples are split among 3 people. How much of an apple does each person receive?"

Two apples split among 3 people - like the first 2 questions, this also equals 2/3.

"Three dogs each drink 2 cups of water. How many cups of water do the dogs drink in all?"

Three dogs EACH drink 2 cups of water means that the answer is 2*3=6 cups.

"Three cupcakes are divided among 2 children. How much of a cupcake does each child receive?"

Three cupcakes are split between 2 children - they will each get 3/2 of a cupcake, or 1 1/2.

Step-by-step explanation:

Johnny mows lawns after school and earns $10 per hour.

Let the number of hours h mows = x

Total earning of Johnny = $10x

If the earning is represented by the variable 'y' equation representing the total earnings will be.

y = 10x

Table for Input output values,

x      0        1          2           3          4

y      0        10       20         30       40

Hope that helps!

Answer: Option D: Inequality.

Step-by-step explanation:

A relation between two unequal values that are compared using the symbols > and <, such like:

A < B    (A is less than B)

A > B (A is greater than )

Are called inequalities.

This is because this is a relation between two unequal values.

Then the correct option is D.

Answer:

I think the answer will be 20. It is oppsite sides and the lines look even. The area is small as well. So I think 20˙ will be the best option.

a). 20°

The angle x is equal to 20° because vertical angle.

(0,1) or 1

Answer:

Perhaps the most important reason to study math is because the study of mathematics builds problem-solving skills. All citizens need to know how to reason and analytically think through a problem. The habits of mind associated with learning mathematics trains our brains to seek solutions in a logical way. Math will help you through your everyday life. It could even help you through colleges and or jobs. Paying for stuff in a store you must know how much you have to pay with your money. If your cashier you have to know how much change they need back. Math is super important. It helps with so many things.

Answer:

ratio: 2:1

y = 15

Step-by-step explanation:

The ratio would be 15-11:11-9 = 4:2 = 2:1

This is because you can subtract the x values of the two points with 11.

To find the value of y:

Figure out the equation of the line between the two points by putting it in the form y = mx + b where m is the slope and b is the y-intercept.

To find the slope, use change in y/change in x so:

20 - 5/9-15 = 15/-6 = 5/-2 = -2.5

That means the slope is -2.5, so you have:

y = -2.5x + b

since you know the point (15, 5) is a solution, you can plug x = 15 and y = 5 into the equation:

5 = -2.5 * 15 + b

5 = -37.5 + b

b = 42.5

The equation is: y = -2.5x + 42.5

Then, plug in x = 11 into the equation:

y = -2.5*11 + 42.5

y = -27.5 + 42.5

y = 15

Answer:

61.5

Step-by-step explanation:

12.30 time 5 is 61.5

Answer:

z = [tex]\frac{4x}{y}[/tex]

Step-by-step explanation:

Given z varies directly with x and inversely with y then the equation relating them is

z = k × [tex]\frac{x}{y}[/tex] ← k is the constant of variation

To find k use the condition z = 10 when x = 5 and y = 2, then

10 = k × [tex]\frac{5}{2}[/tex] ( multiply both sides by 2 to clear the fraction

20 = 5k ( divide both sides by 5 )

4 = k

z = [tex]\frac{4x}{y}[/tex] ← equation of variation

The function that models the asked relationship is 4x / y

A variation is a relation between a set of values of one variable and a set of values of other variables.

Given that, z varies directly with x and inversely with y then the equation relating them is,

z = (k × x) / y, where, k is the constant of variation

Finding k by using the condition z = 10 when x = 5 and y = 2, then

10 = (k × 5) / 2

20 = 5k

k = 4

Therefore, the equation of variation is 4x / y

Hence, the function that models the asked relationship is 4x / y

Answer:

Step-by-step explanation:

Answer:    y= -22

Step-by-step explanation:

Set up a proportional relationship and solve  

If y is -6 and x will be 3   then what will y be when x is 11. \

We can represent that situation like this,

[tex]\frac{-6}{y} = \frac{3}{11}[/tex]    cross multiply  

3y = -66     Divide both sides by 3

y = -22

Answer:

C. 20 minutes

Step-by-step explanation:

If Victor (V) worked alone, it would take him 30 minutes.

30 * V = 1

V = 1 / 30

When x represents the number of minutes it would take Dennis (D) working alone,

x * D = 1

D = 1 / x

Working together, they would finish in 12 minutes

12 (V + D) = 1

12( 1/30  + 1/x) =1

1/30 + 1/x = 1/12

Multiply all through by x

x/30 + 1 = x/12

x/30 - x/12 = - 1

( 2x - 5x ) / 60 = - 1

- 3x / 60 = - 1

- 3x = -60

x = -60 / -3 = 20 minutes

Answer:

330 + 33 = 363

Step-by-step explanation:

The answers you are looking are 330 and 33.

If you were to take 330 and 33 and add them together, it would equal 363. The question also states if you were to take the 0 off of the first number (330), youd get your second number (33) to equal the sum given.
