The formula for finding the interest on a loan is I = prt. Jack borrows $2,000 for 2 years at a rate of 2%. How much interest will he owe?

Answers

9514 1404 393

Answer:

  $80

Step-by-step explanation:

You are given the principal amount (p=$2000), the annual interest rate (r=.02), and the time in years (t=2). Put the numbers in the formula and do the arithmetic.

  I = prt

  I = ($2000)(0.02)(2) = $80

The pairs of polygons are similar. Give the scale factor of Figure A to figure B

Answers

Answer:

2/5

Step-by-step explanation:

Use two corresponding sides.

In triangle A, look at the side between 1 mark and 2 marks on the angles. Its length is 10.

In triangle B, look at the side between 1 mark and 2 marks on the angles. Its length is 4.

To find the scale factor from A to B, divide a length in B by its corresponding length is A.

4/10 = 2/5

Answer: The scale factor from A to B is 2/5.

Given that Figure A and Figure B are similar polygons, the scale factor of Figure A to Figure B = 5/2.

Recall:

Similar Polygons have corresponding side lengths whose ratio are equal. That is, their pairs of corresponding sides are proportional.The ratio of any of their corresponding side length = scale factor

Given the two pairs of similar polygons, the scale factor of figure A to figure B will be calculated as follows:

A side length of Figure A = 10Corresponding side length of Figure B = 4

Scale factor of Figure A to Figure B = 10/4 = 5/2

Write an equation in standard form whose line is less steep and translated down 7 units.

Answers

Answer:

  6x -5y = 15

Step-by-step explanation:

The given line has a slope of 1.5 and a y-intercept of 4. We assume that "translated down 7 units" means the y-intercept needs to be -3. "Less steep" will mean the slope is less than 1.5. We can make the slope be 1.2, so it will be less steep.

Then the slope-intercept form of the desired line is ...

  y = 1.2x -3

Adding 3-y, this becomes ...

  1.2x -y = 3

Multiplying this by 5 to put it into standard form, we have ...

  6x -5y = 15

_____

Additional comment

Since the lines have different slopes, each point on the original line will be translated up or down by a different amount. We chose the y-intercept as the point to be translated by the specified amount. The question could be more clear on that point, as well as whether lines with negative slope (say, -2) are considered to be "less steep."

I need help asap

Answers

Answer:

10.44318182 or 919/88 or 10 39/88

Step-by-step explanation:

I used my calculator :)

Answer:

Step-by-step explanation:

18 9/11 - 8 3/8

First, we need to convert these fractions to improper fraction,

(18 * 11 + 9 / 11) - (8 * 8 + 3 / 8)

=> 207 / 11 - 67 / 8

Next, we need to find the LCM, the LCM of 8 and 11 = 88 (This is because 8 and 11 share no common factors other than 1, so the LCM will be the product of the 2 numbers)

=> (207 * 8) / (11 * 8) - (67 * 11) / (8 * 11)

=> 1656 / 88 - 737 / 88

So, then we just need to subtract the numerators to get the answer,

=> (1656 - 737) / 88

=> 919 / 88

Now, let us return it to the mixed fraction form,

=> 10 39/88

I do not need 4-6 sentences, but just need main points so I can form my own sentences.

Answers

Answer:

See explanation

Step-by-step explanation:

The place to begin in attempting to solve a quadratic equation is to try to factorize it. If it can not be factorized, then look at the side of equation that contains the variable (x,b,m,n and so on). If that side is a perfect square, try to take square root of both sides.

Also, if the coefficient of the squared term in the equation is 1 and the coefficient of the middle term bearing the variable is an even number, then you can attempt to use completing the square method. Formula method can be adopted as a last resort.

x^2 -4x + 4 =0 can be solved by factorization

X(x-2) - 2(x-2) =0

Hence;

(x-2) (x-2) =0

x= 2 (twice)

(2x-2)^2 = 4 can be solved by taking square root

√[(2x-2)^2] = √4

2x-2 = 2

x= ±2

x^2 + 6x - 11 = 0 can be solved by completing the square

(x + 3)^2 = 11 + 3^2

(x + 3)^2 = 20 taking square root of both sides

x + 3 = ±√20

x + 3 = ±2√5

x= -3 ±2√5

2x^2 - x + 5 = 0 can be solved by formula method

Using

x= -b±√b^2 - 4ac/2a

a= 2, b = -1, c= 5

x= 1 ± √1 - 40/4

x= 1 ± √-39/4

x= 1 ± 39i/4

Which are two numbers that multiply to -20 but add to 1

Answers

Answer:

-4 and 5

Step-by-step explanation:

(-4)(5)

=-20

(-4)+5

=1

The two numbers that multiply to -20 but add to 1 are 5 and -4.

We have,

To find two numbers that multiply to -20 but add to 1, we can set up a system of equations.

Let's assume the two numbers are x and y.

We can set up the following equations based on the given conditions:

Equation 1: xy = -20 (the numbers multiply to -20)

Equation 2: x + y = 1 (the numbers add to 1)

To solve this system of equations, we can use the substitution or elimination method.

Let's use the substitution method here:

From Equation 2, we can rewrite it as y = 1 - x.

Now substitute this value of y into Equation 1:

x(1 - x) = -20

Expanding the equation:

x - x² = -20

Rearranging the equation:

x² - x - 20 = 0

Now we have a quadratic equation.

We can factor it or use the quadratic formula to find the values of x.

Factoring the quadratic equation, we get:

(x - 5)(x + 4) = 0

Setting each factor equal to zero, we have:

x - 5 = 0 or x + 4 = 0

Solving for x, we get:

x = 5 or x = -4

Now, substitute these values of x back into Equation 2 to find the corresponding values of y:

For x = 5:

y = 1 - x = 1 - 5 = -4

For x = -4:

y = 1 - x = 1 - (-4) = 5

Therefore,

The two numbers that multiply to -20 but add to 1 are 5 and -4.

The mango is considered the "king of fruits" in many parts of the world. Mangoes are generally harvested at the mature green stage and ripen up during the marketing process of transport, storage, and so on. During this process, about 30% of the fruit is wasted. Because of this, the impact of harvest stage and storage conditions on the postharvest quality are of interest. In this experiment, the fruit was harvested at 80, 95, or 110 days after the fruit setting (the transition from flower to fruit) and then stored at temperatures of 20, 30, or 40 degrees centigrade. For each harvest time and storage temperature, a random sample of mangoes was selected, and the time to ripening was measured.
