We must first determine the total price of the bell peppers in order to determine the number of pounds Paula purchased. Paula bought a total of   [tex]2.8[/tex] pounds of bell peppers.

To determine the total pounds of bell peppers Paula bought, we first need to find the total cost of the bell peppers.

The cost of the red bell peppers is $2.56 and the cost of the green bell peppers is $ [tex]1.92[/tex] , so the total cost of both types of bell peppers is:

$ [tex]2.56[/tex] + $ [tex]1.92 =[/tex]$ [tex]4.48[/tex]

Since both types of bell peppers cost $[tex]1.60[/tex] per pound, we can use this information to find the total weight of the bell peppers.

Let x be the total weight of the bell peppers. Then we can set up the following equation:

$ [tex]1.60\times =[/tex]$[tex]4.48[/tex]

To solve for x, we divide both sides by $[tex]1.60[/tex]:

[tex]x = $4.48 / $1.60[/tex]

Answer:   2.8 pounds of bell pepper bought by Paula

Step-by-step explanation:

Given that :

At the grocery store, the amount spent by Paula :

The amount spent on red bell pepper =  $2.56

The amount spent on green bell pepper = $1.92

the total amount spent = $2.56+$1.92 = $4.48

If both the bell peppers are at  $1.60 per pound, then the total pounds of bell pepper Paula bought

= $4.48/ $1.60

= 2.8 pounds

Solution:

Therefore the number of pounds of bell pepper bought by Paula is 2.8.

The area of the Tri-Tri-Again board game is 3 1/8 square feet.

To calculate the area of a triangle, we need to know the length of its base and its height. In this case, Bridget's Tri-Tri-Again board game is in the shape of a triangle with a base of 1 1/4 feet and a height of 2 1/2 feet. To find the area of the triangle, we can use the formula for the area of a triangle, which is 1/2 x base x height.

We first convert the mixed numbers to improper fractions. The base is 5/4 feet and the height is 5/2 feet. We can then substitute these values into the formula to get:

Area of triangle = 1/2 x 5/4 feet x 5/2 feet

Area of triangle = 25/8 square feet

We can simplify the answer by dividing the numerator and denominator by the greatest common factor of 25 and 8, which is 1. This gives us:

The equation of the line of reflection is y = (−13 / 45)x − (1376 / 45) in point-slope form.

To find the equation of the line of reflection between the points (-9, 12) and (17, -78), we first need to find the midpoint of the line segment joining these two points, which will lie on the line of reflection. The midpoint formula is:

[(x₁ + x₂) / 2, (y₁ + y₂) / 2]

Using the coordinates of the two given points, we get:

[(−9 + 17) / 2, (12 − 78) / 2] = [4, −33]

So, the midpoint is (4, −33).

Next, we need to find the slope of the line of reflection. This is equal to the negative reciprocal of the slope of the line passing through the two given points, since the line of reflection is perpendicular to this line. The slope of the line passing through the two given points is

m = (y₂ − y₁) / (x₂ − x₁) = (−78 − 12) / (17 − (−9)) = −90 / 26 = −45 / 13

So, the slope of the line of reflection is:

m' = −1 / m = −13 / 45

Finally, we can use the point-slope form of the equation of a line, with the midpoint we found as the point and the slope we calculated as the slope which is

y − (−33) = (−13 / 45)(x − 4)

y + 33 = (−13 / 45)x + (52 / 45)

Lola has 9/8 cups of rice left to use for the rice pudding.

What is fraction?

A fraction is a mathematical term that represents a part of a whole or a ratio between two quantities.

To find out how much rice Lola uses for the rice pudding, we need to first determine how much rice she used for the sushi rolls.

Lola used 3/4 of the 4 1/2 cups of rice for the sushi rolls. To calculate this, we can multiply:

4 1/2 cups x 3/4 = (9/2) x (3/4) = 27/8 cups

So Lola used 27/8 cups of rice for the sushi rolls.

To find out how much rice Lola has left for the rice pudding, we need to subtract the amount she used for the sushi rolls from the original amount of rice she had:

4 1/2 cups - 27/8 cups = 36/8 cups - 27/8 cups = 9/8 cups

Cost of bagels = 50 - 1.75 - 33.5 = 14.75

No. of bagels = 14.75/2.95 = 5

Answer:

You bought 5 bagels.

Step-by-step explanation:

Since you buy a coffee every day and it says "after 10 days" you multiply the price of the coffee by 10:     $3.35 * 10 = $33.5  

It also says that the remaining balance on the gift card is $1.75. So you need to subtract that from the original balance, 50:    $50- $1.75 = $48.25  -  this is the amount of money you spent.

Next, you subtract the price of all the coffees you bought from the amount of total money you spent over the course of 10 days.  $48.25 - $33.5 = $14.75

This remaining money is for the bagels that you bought on some days. The last step should be to divide $14.75 by the price of one single bagel:

$14.75 / 2.95 = 5  

You bought 5 bagels.

well, the amount off from the original 125 is just 125 - 87.50 = 37.50.

now, if we take 125(origin amount) as the 100%, what's 37.50 off of it as a percentage?

[tex]\begin{array}{ccll} Amount&\%\\ \cline{1-2} 125 & 100\\ 37.50& x \end{array} \implies \cfrac{125}{37.50}~~=~~\cfrac{100}{x} \\\\\\ 125x=3750\implies x=\cfrac{3750}{125}\implies x=30[/tex]

To determine what percent off the sale for something was, we need to use the formula for percent off calculation.

What is percent off? The percent off is used to refer to the reduction in price or value of something. The percent off calculation is used to determine the amount of discount in percentage of the original price or value.

What is the formula for percent off calculation? The formula for percent off calculation is as follows:

percent off = (discount / original price) x 100, where,discount = original price - sale price

original price = $125 sale price = $87.50

Substitute the given values into the formula and simplify.

percent off = (discount / original price) x 100percent off =

(($125 - $87.50) / $125) x 100percent off

(37.50 / 125) x 100percent off

⇒ 0.3 x 100percent off = 30%

Therefore, the percent off the sale was 30%.

Let's assume that the length of the rectangle is "x".

Since the width is 3 times the length, the width can be represented as "3x".

The perimeter of a rectangle is given by the formula:

P = 2(l + w)

where P is the perimeter, l is the length, and w is the width.

Substituting the values given in the problem, we have:

60 = 2(x + 3x)

Simplifying, we get:

60 = 8x

Dividing both sides by 8, we get:

x = 7.5

Now that we know the length, we can find the width:

width = 3x = 3(7.5) = 22.5

Therefore, the width of the rectangle is 22.5.

Answer:

Answer: 22.5

Step-by-step explanation:

Let L be the length of the rectangle, and W be the width.

From the problem, we know that:

The perimeter of the rectangle is 60, which means that:

2(L + W) = 60

L + W = 30

The width is 3 times the length:

W = 3L

Substituting W = 3L into the first equation, we get:

L + 3L = 30

4L = 30

L = 7.5

Therefore, the width is:

W = 3L = 3(7.5) = 22.5

So, the width of the rectangle is 22.5. Answer:  22.5

May would therefore save $621,470.85 in interest costs if she opted for a 15-year simple interest mortgage ($798,750 - $177,279.15).

The sum of money that even a lender charges a loan for the usage of money over a certain period of time is known as interest. It is frequently represented as a proportion of the sum lent or borrowed and can be either simple or compound. Simple interest is determined by that of the principal amount alone, while interest expense is determined by the principal amount and the total amount of interest that has accrued. A key idea in banking, interest is utilised in a number of credit derivatives, including bonds, savings accounts, and loans.

given

May would save on interest costs if she chose a 15-year simple interest mortgage because the loan would be repaid sooner. Using the same technique as before but with n = 15 years, we can determine the interest costs for a 15-year mortgage:

PV is equal to PMT* [1 - (1 + r/12)(-n*12)] / (r/12)

Inputting the values provided yields:

355000 = PMT * [1 - (1 + 0.595%/12)^(-15*12)] / (0.595%/12)

PMT = $3,208.59

Over the course of the loan, the following would be paid in interest:

I equals PMT*n - PV.

I = $3,208.59 * 15 - $355,000

I = $177,279.15

The solution for x is -21 when rectangle JKLM below, JN = 44.

If MN = -2x + 2,

What is the rectangle?

A rectangle is a geometric shape with four sides and four right angles. It is a quadrilateral in which opposite sides are equal in length and parallel to each other, and adjacent sides are perpendicular to each other.

To solve for x, we can use the given information that JN = 44 and MN = -2x + 2 in the rectangle JKLM.

Since JN is a side of the rectangle and is equal to 44, and MN is also a side of the rectangle and is equal to -2x + 2, we can set up the equation:

JN = MN

44 = -2x + 2

Now we can solve for x:

Add 2x to both sides:

44 + 2x = 2

Subtract 2 from both sides:

44 + 2x - 2 = 0

42 + 2x = 0

Subtract 42 from both sides:

42 + 2x - 42 = 0 - 42

2x = -42

Finally, divide both sides by 2 to isolate x:

2x / 2 = -42 / 2

x = -21

Hence, the solution for x is -21.
