Good Luck!

Becky has 5 quarters left.

Becky starts with 4 quarters and then receives an additional 3 quarters from her mom, giving her a total of 7 quarters. After spending 2 quarters on candy, she subtracts those from her total, leaving her with 5 quarters remaining.

To solve the chocolate problem, we need to work backward from the information given.

Lisa ends up with 6 chocolates, which means before Lisa received her half, there must have been 12 chocolates remaining (since 6 is half of 12).

Jenny ate 2 chocolates before that, so she originally had 14 chocolates.

Therefore, the correct answer is C. 14.

Hey there!!

Equation given :

S = 2hl + 2hw + 2lw

... S = 2 ( hl + hw + lw )

S / 2 = hl + hw + lw

S / 2 = h ( l  + w ) + lw

S / 2 - lw = h ( l + w )

S - 2lw / 2 = h ( l + w )

( S - 2lw / 2 ) / ( l + w ) = h

( S - 2lw / 2l + 2w ) = h

[tex]\frac{S-2lw}{2l+2w} = h[/tex]

Hope my answer helps!!

To solve the formula S=2hl+2hw+2lw for h, rearrange the formula using basic algebra. The final formula for h is h = (S - 2lw) / (2l + 2w).

The formula for the surface area S of a rectangular prism is S=2hl+2hw+2lw, where l is the length,w is the width, and h is the height. To solve this formula for height h, the formula needs to be rearranged with basic algebra.

Start by subtracting 2lw from both sides of the equation, which leaves us with  S - 2lw = 2hl + 2hw. Then, factor out the h from the right side of the equation, you get S - 2lw = h(2l + 2w).

Finally, to solve for h, divide both sides of the equation by (2l + 2w). The final formula to solve for height h would be h = (S - 2lw) / (2l + 2w).

Hello 156339

Since we know the amount of money is always decreasing, then we should know to subtract by 35. Because 2.25 is the cost per meal and x is the number of meals, the total cost should be 2.25x, which is correct because y is the amount of money left over.

Our final equation would be:

y = 35 - 2.25x

:)

The relationship between Timothy's beginning funds, cost of meals, and money left can be represented as y = 35 - 2.25x, where x is the number of meals bought and y is the remaining money.

The relationship between the amount of money Timothy started with, the cost of meals he bought, and the money he had left at the end of the week can be represented with a simple linear equation. The key detail provided in your question is that Timothy started with $35 and his meals cost $2.25 each (we can represent the number of meals as x). We can also denote the amount of money he has left at the end of the week as y. We can then write the equation as: y = 35 - 2.25x. With each meal Timothy buys, his remaining money (y) is reduced by $2.25.

I have attached a photo of the work written for this question:

The original price of the used car, before the 25% reduction, was approximately $8,000. This was calculated by considering that $6,000 represents 75% of the original price.

The question is related to percentage and price, which falls under the realm of Mathematics. To find the original price of the car, you must consider that the price after the 25% discount was $6,000. This 25% reduction means that $6,000 represents 75% of the original price because 100% - 25% equals 75%. To find the original price (which is 100%), you can set up a simple equation and solve for the original price using cross multiplication. The equation will look like this:

75/100 = 6000/x

When you cross multiply and solve for x, the result is $8,000. So, the original price of the car was approximately $8,000.

Step-by-step explanation:

Final answer:

To estimate the monthly expenses, we calculate each monthly cost including the bi-weekly mortgage paid twice a month, phone charges, electric bill, and groceries multiplied by the average number of weeks per month for a total of $1,728.64.

Explanation:

To estimate the monthly expenses based on the provided costs, we need to calculate the monthly totals of each category. Here's the breakdown:

Bi-weekly mortgage: Since a month roughly consists of 4 weeks, a bi-weekly amount would be paid twice. Therefore, $576 × 2 = $1,152 for the mortgage per month.

Monthly phone charges: This cost is already on a monthly basis, so it's $44.95 for the phone.

Electric bill: The electric bill from last month was $105.88 and we'll use this as an estimate for the current month as well.

Groceries: Groceries cost about $98/week. As there are roughly 4.345 weeks in a month (52 weeks in a year divided by 12 months), we'll multiply the weekly cost by this factor: $98 × 4.345 ≈ $425.81 for groceries.

Adding these expenses, the total estimated monthly expenses would be $1,152 (mortgage) + $44.95 (phone) + $105.88 (electric) + $425.81 (groceries) = $1,728.64.

Question 1:

For this case we have:

The value of the x coordinate of the vertex is with the equation given by:

[tex]x = -\frac{b}{2a} \\[/tex]

Where b = -12 and a = -1

therefore,

[tex]x =- \frac{-12}{2(-1)} \\\\x = -6\\[/tex]

To find the coordinate and substitute in the equation:

[tex]y = - (- 6) ^ 2-12 (-6) -32\\\\y = 4\\[/tex]

Answer:

The coordinates of the vertex are (-6.4)

Question 2:

For this case we have the following equation:

[tex]y = -x ^ 2 - 12x - 32\\[/tex]

By definition, to find the intercept point with the y axis, we make x = 0 and substitute as shown below:

[tex]y = - (0) ^ 2-12 (0) -32\\\\y = -32\\[/tex]

Thus, the intercept point with the y axis is given by (0, -32)

Answer:

 the y-intercept is (0, -32)

Question 3:

For this case we have the following equation:

[tex]y = -x ^ 2 - 12x - 32\\[/tex]

The zeros of the function are given by the cut points with the x axis, so, equaling the equation to zero and clearing x we ​​have:

[tex]0 = -x ^ 2 - 12x - 32\\[/tex]

Rewriting the equation we have:

[tex]0 = x ^ 2 + 12x +32\\[/tex]

Factoring has the following:

[tex](x + 4) (x + 8) = 0\\[/tex]

Thus, the solutions are given by:

[tex]x = -4 \\\\x = -8\\[/tex]

Therefore, the zeros of the equation are (-4.0) and (-8.0)

Answer:

(-4.0) and (-8.0)

A dilation is a transformation that shrinks or stretches a figure by multiplying or dividing each point by a scale factor.

A transformation that shrinks or stretches a figure is called a dilation. A dilation is a transformation that changes the size of the figure without changing its shape. It can either shrink the figure, making it smaller, or stretch it, making it larger.

During a dilation, each point of the figure is multiplied or divided by a scale factor. If the scale factor is greater than 1, the figure is stretched. If the scale factor is between 0 and 1, the figure is shrunk.

For example, if we have a triangle and apply a dilation with a scale factor of 2, each side of the triangle will be multiplied by 2, resulting in a larger triangle.

Hey there!

Apply  fraction cross multiply: if a/b = c/d , then  a *d = b*c

2 ( 5x - 2 ) = ( 2x + 4 ) * 4

expand : 2 (5x-2 )  => 2*5x - 2*2 => 10x - 4

expand : ( 2x +4 ) * 4 =>  2x * 4 + 4*4 => 8x + 16

10x - 4 = 8x+16

add 4 to both sides:

10x-4+4 = 8x+16+4

simplify :

10x  = 8x + 20

subtract 8x from both sides:

10x -8x = 8x+20-8x

simplify:

2x = 20

Therefore:

x = 20 / 2

x = 10

Step 1. Simplify 2/3x to 2x/3

2x/3 + 4 = 4/5x - 2

Step 2. Simplify 4/5x to 4x/5

2x/3 + 4 = 4x/5 - 2

Step 3. Multiply both sides by 15 (the LCM of 3,5)

10x + 60 = 12x - 30

Step 4. Subtract 10x from both sides

60 = 12x - 30 - 10x

Step 5. Simplify 12x - 30 - 10x to 2x - 30

60 =2x - 30

Step 6. Add 30 to both sides

60 + 30 =2x

Step 7. Simplify 60 + 30 to 90

90 = 2x

Step 8. Divide both sides by 2

90/2 = x

Step 9.  Simplify 90/2 to 45

45 = x

Step 10. Switch sides

x = 45

Final answer:

The total area when the two given areas are added together, after converting them into the same unit (square meters), is 17,078,004 m².

Explanation:

The student is asking to perform an addition of two figures that represent areas in different units (square kilometers, hectares, and square meters). To solve this, we need to convert all the areas to the same unit, for instance, square meters (m²), and then add them together. Here's the conversion and addition step-by-step:

Convert 5 square kilometers (sq.km) to square meters: 5 sq.km = 5 × (1,000²) = 5,000,000 m².

Convert 95 hectares (ha) to square meters: 95 ha = 95 × 10,000 = 950,000 m².

Add the square meters: 5,000,000 m² + 950,000 m² + 8,994 m² = 5,958,994 m².

For the second area, convert 11 sq.km to m²: 11 sq.km = 11 × (1,000²) = 11,000,000 m².

Convert 11 ha to m²: 11 ha = 11 × 10,000 = 110,000 m².

Add the square meters: 11,000,000 m² + 110,000 m² + 9,010 m² = 11,119,010 m².

Finally, add the two total areas in m²: 5,958,994 m² + 11,119,010 m² = 17,078,004 m².

Answer:

The translation is 3 units left and 2 units down

Step-by-step explanation:

we know that

Point A is located at (1,5) and point A’ is located at (-2,3)

so

The rule of the translation is

(x,y) -----> (x+a,y+b)

(1,5) ----> (-2,3)

Find the values  of a and b

1+a=-2 ----> a=-2-1 ----> a=-3

5+b=3 ----> b=3-5 ----> b=-2

so

The rule of the translation is

(x,y) -----> (x-3,y-2)

That means -----> The translation is 3 units left and 2 units down
