Answers

Answer 1

Answer:

a. $1240

b. $2020

c. 8.3 years

d. 16.7 years

Step-by-step explanation:

Using the simple interest formula, I = Prt, we solve as follows.

a.

I = 1000 × 0.06 × 4 = 240

1000 + 240 = 1240

Answer: a. $1240

b.

I = 1000 × 0.06 × 17 = 1020

1000 + 1020 = 2020

Answer: b. $2020

c.

$1500 - $1000 = $500

Interest is $500

500 = 1000 × 0.06 × t

t = 8.3

Answer: c. 8.3 years

d.

$2000 - $1000 = $1000

Interest is $1000

1000 = 1000 × 0.06 × t

t = 16.7

Answer: d. 16.7 years

Answer 2

Answer:

Please note I have assumed the interest is compounded annually.

a)  $1,262.48

b)  $2,692.77

c)  7 years

d)  12 years

Step-by-step explanation:

Assuming the interest is compounded annually.

[tex]\boxed{\begin{minipage}{7 cm}\underline{Annual Compound Interest Formula}\\\\$ A=P\left(1+r\right)^{t}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]

Given:

P = $1,000r = 6% = 0.06

Substitute the given values into the formula to create an equation for A in terms of t:

[tex]\implies A=1000(1+0.06)^t[/tex]

[tex]\implies A=1000(1.06)^t[/tex]

Part (a)

To calculate how much will be in the account after 4 years, substitute t = 4 into the equation:

[tex]\implies A=1000(1.06)^4[/tex]

[tex]\implies A=1000(1.2624769...)[/tex]

[tex]\implies A=1262.4769...[/tex]

Therefore, there will be $1,262.48 in the account after 4 years.

Part (b)

To calculate how much will be in the account after 17 years, substitute t = 17 into the equation:

[tex]\implies A=1000(1.06)^{17}[/tex]

[tex]\implies A=1000(2.69277278...)[/tex]

[tex]\implies A=2692.77278...[/tex]

Therefore, there will be $2,692.77 in the account after 17 years.

Part (c)

To calculate how many years it will take for the account to contain $1,500, substitute A = 1500 into the equation and solve for t:

[tex]\implies 1500=1000(1.06)^t[/tex]

[tex]\implies 1.5=(1.06)^t[/tex]

[tex]\implies \ln 1.5=\ln (1.06)^t[/tex]

[tex]\implies \ln 1.5=t \ln (1.06)[/tex]

[tex]\implies t=6.95851563...[/tex]

Therefore, it would take 7 years for the account to contain $1,500.

Part (d)

To calculate how many years it will take for the account to contain $2,000, substitute A = 2000 into the equation and solve for t:

[tex]\implies 2000=1000(1.06)^t[/tex]

[tex]\implies 2=(1.06)^t[/tex]

[tex]\implies \ln 2=\ln (1.06)^t[/tex]

[tex]\implies \ln 2=t \ln (1.06)[/tex]

[tex]\implies t=11.8956610...[/tex]

Therefore, it would take 12 years for the account to contain $2,000.

What is the length of DH ?

___ centimeters

Answers

Using Pythagoras theorem the side length of DH is 9cm

Pythagoras's Theorem

Pythagoras theorem states that “In a right-angled triangle,  the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.

To find the value of DH, we can use Pythagoras's theorem to find the length of HC

EC² = EH² + HC²

25² = 20² + HC²

HC² = 25² - 20²

HC² = 225

HC = √225

HC = 15

Using Pythagoras's theorem again, we can find DH

HC² = DC² + DH²

15² = 12² + DH²

DH = 9

The length of DH is 9cm

Five identical rectangular pieces of cloth of different prints when arranged as shown form a square patch. If the perimeter of each rectangular piece is 48 cm, what is the perimeter of the square patch?
(With explanation)

Answers

Answer:

Perimeter of the square patch is 240 cm.

Step-by-step explanation:

If the perimeter of each rectangular piece is 48 cm, then the length of each side of each rectangular piece is 12 cm. When the rectangular pieces are arranged to form a square patch, the patch will have 5 rows and 5 columns of rectangular pieces. Since the rectangular pieces are identical, the length of each side of the square patch will be 5 times the length of one side of a rectangular piece. Therefore, the length of each side of the square patch will be 5 * 12 cm = 60 cm.

The perimeter of the square patch is the sum of the lengths of all four sides of the patch. Since all sides of the patch have the same length, the perimeter of the square patch will be 4 * 60 cm = 240

Answer: 20°

Step-by-step explanation:

The sum of all the interior angles of a triangle is 180°

So to find the missing angle you just need to subtract 25° and 135° from 180°, which equals 20°

All three angles in a triangle must add up to 180 degrees. So first, you add 135 and 25 which equals 160. Then to find the missing angle you subtract 160 from 180 to get 20 degrees as your final answer.

x + 25 + 135 = 180
x + 160 = 180
x = 180-160
x = 20

Answers

Answer:

4.

Step-by-step explanation:

strange phrasing of the answer options.

anyway, the product of 56 and 5/9 is

56 × 5/9 = 56×5 / 9 = 280/9 = 31 1/9

or as the definition says 31 and 1/9.

because 31×9 = 279.

280 - 279 = 1

so, there is a remainder of 1, which means 1/9.

280/9 = 279/9 + 1/9 = 31 1/9

Given: Beth bought 16 tickets to a movie, where adult tickets cost $8.00 and senior citizen tickets cost $5.00. She spent a total of $120.

We let adult tickets be x and

let senior citizens' tickets be y.

x + y = 16....(1)

8x + 5y = 120...(2)

From equation(1)

x = 16 - y

we put the value of x in equation(2) and we get

= 8(16 - y) + 5y = 120

= 128 - 8y + 5y = 120

= 3y = 8

y = 8/3

Now, we put the value of y in equation(1) and we get

x = 16-8/3

x = 40/3

The average daily loss of Anthony's shop in April is $20.

How is the average daily loss determined?

The average daily loss is the total net profit (loss) divided by the number of days in April.

An average is the mean of the value in a data set, which is determined as the quotient between the total value and the number of items.

Days in April = 30

Daily profit in 12 days = $400

Daily loss in 18 days (30 - 12) = $300

Total daily profit = $4,800 ($400 x 12)

Total daily loss = $5,400 ($300 x 18)

Net daily loss = $600 ($5,400 - $4,800)

Answers

When 13% VAT is levied on Rs 5000, the total price becomes Rs. 5650. This amount is Rs. 150 more than Rs. 5500.

VAT refers to value-added tax, a flat consumption tax levied on goods and services. It is most commonly charged in the countries of the EU. VAT is calculated by multiplying the percentage given by the original price.

VAT amount = percentage × original price

= 13% × 5000

=  Rs. 650

We must add the VAT amount to the original amount to get the total price.

= 5000 + 650

= Rs. 5650

and the price of stock B can be described by ...

  B = 15.37 -0.15(x -12)

Solution

The two prices will be the same when ...

  A = B

  14.62 +0.13(x -9) = 15.37 -0.15x -12 . . . . . substitute for A and B

  0.13x +13.45 = -0.15x +17.17

  0.28x = 3.72 . . . . . . . . . add 0.15x-13.45

  x = 3.72/0.28 = 13 2/7 . . . . . . hours after midnight

To find the number of hours after noon, we need to subtract 12 from this number. 13 2/7 -12 = 1 2/7

The two stocks will be the same price after 1 2/7 hours.

Additional comment

That's about 1:17 p.m.

The wording "in how many hours" is a bit ambiguous, since there are two different time references given in the problem. We assume we want hours after the later time reference, noon.

a cook uses 1 3/4 teaspoons if salt to make 3 1/2 pounds of pasta. what is the unit rate in teaspoons per pound , at which the cook uses salt to make pasta?

Answers

The unit rate in teaspoons per pound would be 1/2 teaspoons per pound.

What is the unit rate?

A unit rate means a rate for one or something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

The number of teaspoons:

                                      [tex]=1\frac{3}{4}\\\\=\frac{4+3}{4}\\\\=\frac{7}{4}[/tex]

Amount of pasta:

                              [tex]=3\frac{1}{2}\\\\=\frac{6+1}{2}\\\\=\frac{7}{2}[/tex]

Now the unit rate = number of teaspoons/ amount of pasta

                             [tex]=\frac{7/4}{7/2}\\\\=\frac{1}{2}\\[/tex]

Hence, the unit rate in teaspoons per pound would be 1/2 teaspoons per pound.

Write quadratic functions given three points in a plane

1) Find the equation for the parabola using the linear system (pictured)
2) Write three equations using three ordered pairs
3) Write the linear system
4) Solve the system using substitution then elimination, show all work and steps
5) List the three parameter values
6) Write the quadratic equation

The resulting quadratic equation that represents the parabola is y = 2 · x² - 7 · x - 4.

How to determine the quadratic equation that represents a parabola

In this problem we find the representation of a parabola. Parabolae are always represented by quadratic equations, that is, polynomials of the form:

y = a · x² + b · x + c

Where:

x - Independent variable.y - Dependent variable.a, b, c - Real coefficients.

First, write the coordinates of the three points highlighted on Cartesian plane:

(x₁, y₁) = (- 1, 5), (x₂, y₂) = (0, - 4), (x₃, y₃) = (4, 0)

Second, create a system of linear equations based on the three points and the equation of the parabola:

a - b + c = 5

c = - 4

16 · a + 4 · b + c = 0

Third, solve the system of linear equations:

Step 1 - Second equation:

c = - 4

Step 2 - Second equation in the first and third equations:

a - b = 9

16 · a + 4 · b = 4

Step 3 - Clear a in the first equation on Step 2:

a = 9 + b

Step 4 - Substitute a in the second equation on Step 2:

16 · (9 + b) + 4 · b = 4

144 + 20 · b = 4

20 · b = - 140

b = - 7

Step 5 - By the equation on Step 3:

a = 9 - 7

a = 2

Fourth, write the solution of the system of linear equations:

(a, b, c) = (2, - 7, - 4)

Fifth, write the resulting quadratic equation:

y = 2 · x² - 7 · x - 4

Define converse.

A conditional statement's opposite is produced when the hypothesis and conclusion are switched around. The converse statement is known as p⇒ q in geometry. In logic and mathematics, the reverse of a categorical or implicational statement is the outcome of reversing its two constituent statements, and it is denoted by the symbol q⇒ p. The opposite of the implication P ⇒ Q is Q P. The inverse of the categorical assertion All S are P is that All P are S.

Read the short story from Myths and Legends of the Great Plains. Then answer the question that follows. Long ago, in the beginning, Deer had no horns. His head was smooth like a doe's. Now Deer was a very fast runner, but Rabbit was a famous jumper. So, the animals used to talk about it and wonder which could go the farther in the same time. They talked about it a great deal. They decided to have a race between the two, and they made a pair of large antlers to be given to whoever could run the faster. Deer and Rabbit were to start together from one side of a thicket, go through it, and then turn and come back. The one who came out of the thicket first was to receive the horns. On a certain day all the animals were there. They put the antlers down on the ground to mark the starting point. Everyone admired the horns. But Rabbit said, "I don't know this part of the country; I want to look through the bushes where I am to run." So, the Rabbit went into the thicket, and stayed a long time. He was gone so long the animals suspected he was playing a trick. They sent a messenger after him. Right in the middle of the thicket he found Rabbit, gnawing down the bushes and pulling them away to make a clear road for himself. The messenger came back quietly and told the animals. When Rabbit came back, they accused him of cheating. Rabbit said, "No," but at last they all went into the thicket and found the road he had made. Therefore, the animals gave the antlers to Deer, saying that he was the better runner. That is why deer have antlers. And because Rabbit cut the bushes down, he is obliged to keep cutting them down, as he does to this day.How does the juxtaposition of the two main characters add to the meaning of this story?
