To find the number of quarters in Lucy's $9.50 coin collection, divide the total value by the value of one quarter. $9.50 divided by $0.25 equals 38, so Lucy has 38 quarters in her collection.

The question asks to calculate the number of quarters in Lucy's coin collection, given the total value is $9.50. Since each quarter is worth 25 cents, or $0.25, we can use division to find the number of quarters. The calculation is as follows:

Total value in dollars ($9.50) divided by the value of one quarter ($0.25) equals the number of quarters.

So, $9.50 ÷ $0.25 = 38 quarters.

Therefore, Lucy has 38 quarters in her collection.

Answer:

600

Step-by-step explanation:

first you need to find the calories for the entire batter:

12 muffins x 250 cal = 3000 cal

then you divide the total calories by 20:

3000/20 = 150

then multiply 150 by 4:

150 x 4 = 600

To find the caloric content of each mini-muffin, divide the total calories in the recipe by the new yield to find that each mini muffin is 150 calories. Consuming 4 mini muffins will total 600 calories.

The caloric content of a full-size muffin is 250 calories. If we reduce the size of the muffins we make from the recipe, it doesn't alter the total caloric content of the whole batch – it just redistributes those calories across more muffins. To calculate the number of calories in one mini-muffin, we need to divide the total number of calories in the entire recipe (250 calories/muffin * 12 muffins = 3000 calories) by the total yield of mini-muffins, which is 20. This results in 3000 calories/20 mini-muffins = 150 calories per mini-muffin. If you consume 4 mini-muffins, you'd be consuming 4 * 150 calories = 600 calories.

Answer:

(x , 1/2x - 5/2)  where x is a real number.

Step-by-step explanation:

-2x + 4y = -10 ⇔ 4y = 2x - 10 ⇔ y = 1/2x - 5/2

then any couple of the form (x , 1/2x - 5/2) is a solution to the equation

example :

let x = 7 then 1/2x - 5/2 = 1/2(7) - 5/2 = 1

in this case  -2x + 4y = -2(7) + 4(1) = -14 + 4 = -10

Answer:

Carlos would pay lower out-of-pocket costs if he picks over plan B.

Step-by-step explanation:

Let's make the comparison between plan A and plan B, this way:

Medicals bills = US$ 6,350

Plan A

6,350 - 1,200 = 5,150 * 30% = 5,150 * 0.3 = 1,545

Total out-of-pocket costs = 1,200 + 1,545 = $ 2,745

Plan B

6,350 - 1,500 = 4,850 * 25% = 4,850 * 0.25 = 1,212.50

Total out-of-pocket costs = 1,500 + 1,212.50 = $ 2,712.50

Carlos would pay lower out-of-pocket costs if he picks over plan B.

Answer:

37 7/8

Step-by-step explanation:

First you make the equation

14 5/8 = _ - 20 - 3 1/4

They all have to make 14 5/8 so then solve

x+-93/4 = 117/8

x=303/8

Simplified:

x=37 7/8

To solve the equation -20 - 3 1/4 = 14 5/8, start by simplifying the mixed number and converting it to an improper fraction. Then, find a common denominator for the fractions and add them. Simplify and multiply both sides by -2 to eliminate the fractions.

To solve the equation: -20 - 3 1/4 = 14 5/8, you can start by simplifying the mixed number and converting it to an improper fraction.
-20 can be written as -20/1, so the equation becomes:
-20/1 - 13/4 = 117/8.
Next, find a common denominator for the fractions. The common denominator for 1 and 4 is 4, so the equation becomes:
-80/4 - 13/4 = 117/8.
Now, you can add the fractions:
(-80 - 13)/4 = 117/8.
Simplify:
-93/4 = 117/8.
Finally, multiply both sides by -2 to eliminate the fractions:
-93/4 * -2 = 117/8 * -2.
The final answer is:
186/4 = -234/8.
Simplify:
93/2 = -117/4.

The tangent of the angle between two lines can be calculated using the slopes of the lines and applying them in the formula: Tan θ = (m2-m1) / (1 + m1*m2). The slopes of the given lines 2x+3y–5=0 and 5x=7y+3 are -2/3 and 5/7 respectively. These values are used in the formula to get the tangent of the angle.

The subject of the given problem is concerning finding the tangent of the angle in between two lines namely, 2x+3y–5=0 and 5x=7y+3. First, we should understand that the tangent of the angle between two lines can be calculated using the formula:

Tan θ = (m2-m1) / (1 + m1*m2)

Where 'm1' and 'm2' are the slopes of two lines and 'θ' is the angle between them. Firstly, we need to put the equation in the form of y=mx+b to determine the slopes. So, the slope of the first line is -2/3 (m1) and of the second line is 5/7 (m2).

Using these values in the formula, we can find:

Tan θ = ((5/7) - (-2/3)) / (1 + (-2/3)*(5/7))

By calculating the above expression using basic arithmetic you will find the required answer.

Final answer:

The tangent of the angle between the two lines 2x+3y-5=0 and 5x-7y-3=0 is found by calculating the slopes of each line, then using the formula for the tangent of the angle between two lines. The result is a tangent of the angle of -29/11.

Explanation:

To find the tangent of the angle between the given lines, we need to first find the slope of each line. The slope of a line in the form ax + by + c = 0 is -a/b. Thus, the slope of the first line 2x + 3y – 5 = 0 is -2/3, and the slope of the second line 5x - 7y - 3 = 0 is 5/7. Now, using the formula for the tangent of the angle between two lines, which is tan(θ) = (m1 - m2)/(1 + m1*m2), where m1 and m2 are the slopes of the two lines, we get:

tan(θ) = ((-2/3) - (5/7))/(1 + (-2/3)*(5/7))

tan(θ) = (-14/21) - (15/21))/ (1 - (10/21))

tan(θ) = (-29/21) / (11/21)

tan(θ) = -29/11

Therefore, the tangent of the angle between the two lines is -29/11.

Both Adam's expression, d - 0.75d, and Rena's expression, 0.25d, yield the same sale price for the video game, offering different perspectives on calculating the discounted amount.

Adam's expression:

d: represents the original price of the video game in dollars.

-0.75: represents the discount of 75% as a decimal. A negative sign is used to indicate a decrease in price.

d - 0.75d: This expression subtracts the discount (0.75d) from the original price (d) to find the sale price of the video game.

Rena's expression:

0.25: represents the remaining price after the discount, which is 100% - 75% = 25%. This is also expressed as a decimal.

d: represents the original price of the video game in dollars.

0.25d: This expression multiplies the remaining price (0.25) by the original price (d) to find the sale price of the video game.

Both expressions, d - 0.75d and 0.25d, arrive at the same sale price for the video game. They simply represent different mathematical approaches to achieve the same result.

Final answer:

The maximum number of volts that can be placed across the resistor is 20 volts.

Explanation:

The maximum number of volts, E, that can be placed across a resistor is given by the formula E = √(P * R), where P is the number of watts of power that the resistor can absorb and R is the resistance of the resistor in ohms. To find E, we can substitute the given values for P and R into the formula and solve:

E = √(2 * 200) = √(400) = 20 volts

Therefore, the maximum number of volts that can be placed across the resistor is 20 volts.

The maximum number of volts E that can be placed across the resistor is 20 volts.

The maximum number of volts, E, that can be placed across the resistor is given by the square root of the product of power P and resistance R. Therefore, E can be calculated as follows:

[tex]\[ E = \sqrt{P \times R} \][/tex]

[tex]\[ E = \sqrt{2 \text{ watts} \times 200 \text{ ohms}} \][/tex]

[tex]\[ E = 20 \text{ volts} \][/tex]

 The formula provided in the question is [tex]\( E = \sqrt{P \times R} \),[/tex] where E is the maximum number of volts that can be placed across a resistor, P is the power in watts, and R is the resistance in ohms.

This formula is derived from the power equation [tex]\( P = \frac{V^2}{R} \),[/tex]where V is the voltage across the resistor.

Given that the power P is 2 watts and the resistance R is 200 ohms, we substitute these values into the formula to find E:

[tex]\[ E = \sqrt{2 \times 200} \][/tex]

[tex]\[ E = \sqrt{400} \][/tex]

 The square root of 400 is 20, so the maximum number of volts E that can be placed across the resistor is 20 volts.

This is the voltage at which the resistor will absorb the maximum power of 2 watts without being damaged, assuming the resistor is operating at its maximum power rating.

The values required are;

Given:

Mass of the gas = 4 lb

Volume occupied by the gas = 10 ft.³

Required:

Find the density and the specific gravity of the gas

Density:

Therefore, the density of the mass of gas is given as follows;

[tex]Density = \dfrac{4 \ lb}{10 \ ft.^3} = 0.4 \ lb/ft.^3[/tex]

The density of the gas = 0.4 lb/ft.³

Specific gravity:

The specific gravity, s.g. of a gas is the ratio of the density of the gas to the density of air

The density of air ≈ 0.0765 lb/ft.³

The specific gravity of the gas is therefore;

[tex]s.g. = \dfrac{0.4 \ lb/ft.^3}{0.0765 \ lb/ft.^3} = \dfrac{800}{153} \approx 5.23[/tex]
