Find the measure of Angles A, C, D

Answers

Answer:

A= 65 C= 65 and D= 115

Step-by-step explanation:

given a parallelogram .

interior angles sum is 360 degree.

sum of adjacent angles is 180degree.

opposite angles are congruent (B=D).

A + B + C + D = 360

(A + D) + C + 115 = 360 since A and D are adjacent angles .

180 + 115 + C = 360

295 + C = 360

C = 360 - 295

C = 65

D = 115

A = 65

a+b+c+d=360

65 + 65 + 115 + 115 = 360

130 + 230 = 360

360 = 360

how to find principal without interest

Answers

Answer:

Step-by-step explanation:

What Is a Principal Amount?

Principal amount on a loan is the amount borrowed. To better understand, let's look at the story of John. When John bought his first car he didn't have enough money to pay for it in cash, so he had to take out a loan. He borrowed $7,500. According to the terms of the loan, John had to pay it off in five years with an interest rate of 10%. The initial amount that he borrowed, or the $7,500, is called the principal amount of the loan. Keep in mind that the principal amount applies to more than just loans. It can also apply to money that is invested or deposited into an account. For example, if you open a savings account with a $700 deposit, the principal amount is $700.

What About Interest?

Principal amount does not include interest, or a rate paid as a fee for borrowing money. To figure out the amount of interest John paid during the five years, you can use the simple interest formula, which is a formula to calculate interest paid only on the principal amount. This formula is:

or interest equals principal amount times interest rate times amount of time. Using this formula, you will find that the amount of interest on John's $7,500 loan was $3,750. So, at the end of five years, he would end up paying a total of $11,250. This does not include any additional fees that may apply.

Principal Amount Formulas

For John's loan, we were given the principal amount and used it to find the amount of interest. What if we already know the interest rate, amount of interest, and amount of time, but we need to find out the principal amount? We can rearrange the interest formula, I = PRT to calculate the principal amount. The new, rearranged formula would be P = I / (RT), which is principal amount equals interest divided by interest rate times the amount of time.

Let's try this out by finding the principal amount of a loan that has a total interest amount of $18,500 and an annual interest rate of 6.5% over 12 years.

To solve, we input the values into the equation, P = I / (RT). This gives us:

P = $18,500 / (0.065 * 12) = $23,718

The principal amount of the loan is $23,718.

Un jardinier a récolté deux quintaux trois quarts de pommes . Il vend un quintal un quart à un voisin ; il vend aussi 7/10 de quintal sur le marché du village et 2/5 de quintal à un pâtissier .Exprimer à l'aide d'une fraction la quantité de pomme que le jardinier a gardé pour lui .

Answers

Answer:

Step-by-step explanation:

Notez que: un quintal =

une unité de poids égale à 100 kg

Un jardinier a récolté deux quintaux et trois quarts de pommes.

Le nombre total de pommes récoltées = 200 kg + 3/4 du quintal de pommes

= 200 kg + 0,381 kg

= 200,381 kg

Il vend un quintal un quart à un voisin

Le montant qu'il a vendu à un voisin = 100 + 1/4 quintal de pommes

100 + 0,127

= 100,127 kg

Il vend également 7/10 d'un quintal sur le marché du village

= 7/10 × 100 kg

= 70 kg de pommes restantes

2/5 d'un quintal à un pâtissier.

2/5 × 100 kg

= 40 kg de pommes restantes

À l'aide d'une fraction, exprimez la quantité de pomme que le jardinier a gardée pour lui.

La quantité que le jardinier lui a réservée =

200 3/4 kg - (100 1/4 kg + 70 kg + 40 kg)

200,381 kg - (210,127 kg)

Aunt Martina is pricing cakes for a baby shower she is throwing. She wants one large cake shaped like a duckling and also some cupcakes in pastel colors. Sparrowtown Bakery charges $2 for each cupcake, plus $50 for the large cake. Dakota's Sweet Shoppe charges $44 for the large cake and $4 for each cupcake. If Aunt Martina orders a certain number of cupcakes, the cost will be the same at either bakery. What would the total cost be? How many cupcakes would that include?

Answers

Answer:

3 cupcakes

Total of $56

Step-by-step explanation:

First we would need to create an expression for the total of each bakery, which would be the following with x representing the number of cupcakes.

2x + 50

4x + 44

Since we know that the total for both bakeries was the same we can simply make the expressions equal to one another and solve for x.

2x + 50 = 4x + 44 ... subtract 2x on both sides

50 = 2x + 44 ... subtract 44 on both sides

6 = 2x ... divide both sides by 2

3 = x

Finally, we can see that at 3 cupcakes the total for both bakeries will be the same and be a total of

2(3) + 50

6 + 50

$56

Answers

Answer:

a.) $10.50

b.) $45.00

c.) about 66.67%

Step-by-step explanation:

a.) regular price = 15.00

discount = 30% or 0.3

15 x 0.3 = 4.50 ----------> this is the amount that you will have off

15.00 - 4.50 ---------> by subtracting from original price, you have sale price

= $10.50

b.) bought price = 25.00

marked up = 80% or 0.8

25.00 x 0.8 = 20 -------> this will give you 80% of 25

25.00 + 20.00 ------> she sells for 80% higher, so add the numbers

= $45.00

c.) original price = 36.00

bought price = 36.00 - 12.00

= 24

24 / 36 -----> divide bought price by original to find what percentage it is

= .66666 which is rewritten as 66.667%

you can check this by multiplying that percentage by the original price

hopefully this helps a little bit

Step-by-step explanation:

I used pi = 3.14 to get the approximation.

=================================================

Explanation:

This is a three quarter circle since one quarter of it has been taken away.

Let's find the area of the full circle

A = pi*r^2

A = pi*2^2

A = 4pi

Now let's divide by 4 to find the area of just a quarter slice

(4pi)/4 = pi

One quarter slice is pi square units. Since we want three of these quarter slices, this means 3pi is the exact area of the shape shown.

This approximates to 3*pi = 3*3.14 = 9.42
