Answer:

SOOO you got a loan wich means you recieved 700 dollars. u pay 35 dollars each month...

so basically 35*12 wouuld be what u would pay for a year

so 420 dollars is for one year- and yet u got a 700 dolllar loan so u actually are only paying 420 dollars which is 280 interest

Step-by-step explanation:

Answer:

60%

Step-by-step explanation:

The monthly rate is:

35/700 = 0.05

There are 12 months in a year, so the annual rate is:

12 × 0.05 = 0.6

The annual interest rate is 60%.

a) The quantities vary directly

b) The constant of variation is 2.5

Step-by-step explanation:

Lets us revise the direct and inverse variation

∵ 16 factory workers made 40 pieces in a certain amount of time

- If the number of worker increased, then the number of pieces

   increased in the same certain time, if the number of worker

   decreased, then the number of pieces also decrease in the

   same certain time

∴ The the number of workers and the number of pieces produce

   vary directly

∴ Number of pieces produced = k × number of worker

a) The quantities vary directly

∵ The number of worker = 16

∵ The number of pieces produced = 40

- Substitute these values in the equation of variation above

∴ 40 = k × 16

- Divide both sides by 16

∴ k = 2.5

b) The constant of variation is 2.5

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

Explanation:

1/5 of the tiles are indian red

3/10 of the tiles are Tuscan blue

1/6 of the tiles are eucalyptus

x of the tiles are sand, where x is some fraction

The four fractions listed above add to 1. The "1" refers to a whole back splash, in which you can think of "1" as "100%"

-----------

We have the fractions 1/5, 3/10 and 1/6

To combine these fractions, we need a common denominator. In this case, the lowest common denominator (LCD) is 30 as this is the LCM of the denominators 5, 10, and 6.

Let's get each fraction to have a denominator of 30

1/5 = (6/6)*(1/5) = 6/30

3/10 = (3/3)*(3/10) = 9/30

1/6 = (5/5)*(1/6) = 5/30

-----------

So effectively we have these fractions: 6/30, 9/30, and 5/30

They add to the unknown fraction x to get 1

Let's solve for x.

-----------

(1/5) + (3/10) + (1/6) + x = 1

(6/30) + (9/30) + (5/30) + x = 1

(6/30 + 9/30 + 5/30) + x = 1

(6 + 9 + 5)/30 + x = 1

20/30 + x = 1

2/3 + x = 1

x + 2/3 = 1

x+2/3-2/3=1-2/3 ... subtract 2/3 from both sides

x = 1 - 2/3

x = 3/3 - 2/3

x = (3 - 2)/3

x = 1/3

------------

1/3 of the tiles are the color of sand

Final answer:

One third of the tiles will be the color of sand. This is found by adding the fractions of the other colors, simplifying, and subtracting from one whole set of tiles.

Explanation:

To find the fraction of the tiles that will be the color of sand, we first need to calculate the total fraction of tiles that have already been assigned colors: Indian red, Tuscan blue, and eucalyptus. Then we subtract this total from 1, which represents the whole set of tiles, to find the remaining fraction for the sand-colored tiles.

Adding these fractions:

Now, we convert 10/15 to a simplified fraction:

To find the fraction for sand-colored tiles, subtract the total colored fraction from 1:

Therefore, one third of the tiles will be the color of sand.

Answer:

y = 2

Step-by-step explanation:

When line is horizontal, all points on this line have the same value of y.

In this case , all points have to have y = 2.

y = 2, is an equation of horizontal line.

The equation of  line y = 2 represents the horizontal line passing through (-1,2).

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have given a point (-1, 2) on a coordinate plane.

The distance from origin (0, 0) and (0, 2) is 2

And line y = 2 represents the horizontal line that passes through (-1, 2)

Thus, the equation of  line y = 2 represents the horizontal line passing through (-1,2).

Answer:

The trip is 50miles far

Step-by-step explanation:

If they have travel 15miles which is equal to 30% of the trip.

To find how far the trip is.

Let x represent the trip in miles

Therefore:

30% of x is 15miles

30/100 * x = 15miles

x = 15 miles ÷ 30/100

x = 15 miles * 100/30

x = 1500miles/30

x = 50miles

To find the probability of at least one defective microscope in a batch of 50, we first calculate the probability of all 50 being non-defective and then subtract this from 1. The resulting probability of having at least one defective microscope in the batch is approximately 7.96%.

The question is about finding the probability that one of the first 50 microscopes manufactured by LabTech is defective. Given the probability of a microscope being defective is 0.17%, we can calculate this by multiplying the probability of a single microscope being defective by the total number of microscopes.

Firstly, convert the 0.17% to a decimal by dividing by 100, which gives us 0.0017. This is the probability of a single microscope being defective. Then, to find out the probability of at least one out of 50 being defective, we would consider the opposite - the probability of all 50 microscopes being non-defective. If one microscope has a 0.0017 chance of being defective, it has a 1-0.0017 = 0.9983 chance of being non-defective.

The chance of all 50 microscopes being non-defective is [tex](0.9983)^{50} = 0.9204.[/tex] Therefore, the probability of at least one out of 50 being defective is 1 - 0.9204 = 0.0796 or 7.96%.

Final answer:

The probability that at least one of the first 50 microscopes manufactured is defective is calculated using the complement rule, by subtracting the probability of none being defective from 1, the answer is 0.082

Explanation:

To find the probability that at least one of the first 50 microscopes LabTech manufactures is defective, we use the complement rule. The probability that a microscope is not defective is 1 - 0.0017 (since 0.17% as a decimal is 0.0017). To find the probability that none of the microscopes out of the 50 produced are defective, we raise this to the power of 50:

P(no defective microscopes) = [tex](1 - 0.0017)^{50[/tex]

Then, to find the probability that at least one microscope is defective, we subtract this from 1:

P(at least one defective microscope) = [tex]1 - (1 - 0.0017)^{50[/tex]

P(at least one defective microscope)= 1-0.918= 0.082

For this case we must find the solution of the following equation:

[tex]5x + 20 = 7 (x + 2)[/tex]

Applying distributive property on the right side of the equation we have:

[tex]5x + 20 = 7x + 14[/tex]

Subtracting 7x from both sides of the equation:

[tex]5x-7x + 20 = 14\\-2x + 20 = 14[/tex]

Subtracting 20 from both sides of the equation:

[tex]-2x = 14-20[/tex]

Different signs are subtracted and the major sign is placed.

15x^2 - 9x - 25x + 15

15x^2 - 34x + 15

Answer:

Jack is five. so, it's A

Step-by-step explanation:

subtract 4 from both sides of the equation. You can cancel out the four on the left, and get 40 on the right (since you took four away from 44.)

Then, divide by 8 on both sides. The eight is canceled out on the left. eight goes into 40 five times, meaning a=5.

The correct option is (A) 5. To find Jack's age, subtract 4 from both sides of the equation 8a + 4 = 44 and then divide by 8. This results in a = 5, meaning Jack is 5 years old.

To solve the given equation, 8a + 4 = 44, for Jack's age, we first need to isolate the variable a, which represents Jack's age. This can be done by first subtracting 4 from both sides of the equation to undo the addition.

8a + 4 - 4 = 44 - 4

8a = 40

Next, we divide both sides of the equation by 8 to undo the multiplication and solve for a:

8a / 8 = 40 / 8

a = 5

Therefore, Jack's age is 5 years old, which corresponds to option A.
