Answer:

x = 30

y = 15

Step-by-step explanation:

All the angles are 90°, so set 6y and 3x equal to 90, like so:

6y = 90

Divide both sides by 6:

y = 15

Solving for x:

3x = 90

Divide both sides by 3:

x = 30

Step-by-step explanation:

3) in parallelogram opposite angles are equal

6y=90

y=15

x=30

4)In parallelogram ,parallel sides are equal

x=7

y=4

5x + 2y = -4

+ x. -2y. -8

6x = -12

y = 3

I'm going to assume you pasted the question and answers and the fractions for the slope didn't come up.

Solve for the slope using the given values.

Slope formula: y2-y1/x2-x1

= 8-5/5-0

= 3/5

Point slope form: y - y1 = m(x - x1)

Using the point (5, 8) and the slope (3/5), it should look like:

y - 8 = 3/5(x - 5)

Best of Luck!

Answer:

First we need to put all the given information in a table, that way we'll express it better into inequalities.

                                     Cost      Production Max.

Console screen (x)      $600              450

Wide-screen (y)           $900              200

                                 $360,000

We have:

[tex]600x+900y \leq 360,000[/tex]

Because they can't spend more than $360,000 in production.

[tex]x\leq 450\\y\leq 200[/tex]

Because the number of television is restricted.

The profit function is

[tex]P(x,y)=125x+200y[/tex] (this is the function we need to maximize).

First, we need to draw each inequality. The image attached shows the region of solution, which has vertices (0,200), (300,200), (450, 100) and (450,0).

Now, we test each point in the profit function to see which one gives the highest profit.

For (300,200):

[tex]P(300,200)=125(300)+200(200)=37,500+40,000=77,500[/tex]

300 console screen and 200 wide screen give a profit of $77,500.

For (450,100):

[tex]P(450,100)=125(450)+200(100)=56,250+20,000=76,250[/tex]

450 console screen and 100 wide screen give a profit of $76,250.

Answer:

2 ,3 and 5 show repeated multiplication

Step-by-step explanation:

Repeated multiplication : When we multiply any integer by itself many times then it is called repeated multiplication

1)     (1)(9)

By definition it is not repeated multiplication

2)   (one-half) (one-half) (one-half)

By definition it is repeated multiplication

3)     (7)(7)(7)(7)

By definition it is repeated multiplication

4)    (2)(3)(4)(5)(6)

By definition it is not repeated multiplication

5)   (9)(9)(9)(9)(9)(9)

By definition it is repeated multiplication

Hence 2 ,3 and 5 show repeated multiplication

Answer:

its 2 3 5

Step-by-step explanation:

a. Okay, so you multiply the 4.7 and 2.9 together, and then add the exponents

13.63 * 10^10

But we are not done. There can only be one digit in front of the decimal point. So, you move the 13.63 back one place so 1.363. But we have to do this to both sides, so the answer is 1.363 * 10^11.

b. Now you divide the 5.8 and 2, and subtract the exponents.

2.9 * 10^-5

The negative exponent is fine in this case if you were wondering.

c. Expand the scientific notation to 1500, then add the 2491 and then put that in scientific notation is what I would do. You can also express 2491 in scientific notation and add them. Either way you will get 3.991 * 10^3

d. Same thing here except with subtraction. The answer is 6.5 * 10^-4.

This was a little long, sorry. Let me know if you need further explanation. I hope this helps.

Answer:

(2, - 5)

Step-by-step explanation:

The line y = -1 is horizontal: parallel to the y-axis.

The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:

Δy = 3 - ( - 1) = 4

When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change.  The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.

Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).

Step-by-step explanation:

The formula for the tangent of an angle is the length of the opposite side divided by the length of the adjacent side. Therefore, the tangent of angle x is 420/2000=0.21. Taking the arctangent of that to get the angle, you get about 12 degrees. Hope this helps!

Answer:

43 paperback books

Step-by-step explanation:

7.50(15) + 1.25x = 166.25

112.50 + 1.25x = 166.25

Subtract 112.50 from both sides

(112.50 - 112.50) + 1.25x = (166.25 - 112.50)

1.25x = 53.75

Divide 1.25 from both sides

The surface area that will be frosted with icing is 205in²

It will be equal to the sum between the top surface, which measures:

S = 13in*9in = 117 in²

And the four lateral sides, two of them measure:

s' = 2in*9in = 18in²

The other two measures:

s'' = 13in*2in = 26in²

Then the total surface area that must be frosted is:

SA = 117 in² + 2*( 18in²) + 2*(26in²) = 205 in²

So we conclude that the correct option is C.

Answer:

if and only if it has two pairs of parallel sides

Step-by-step explanation:

The definition says that a paralellogram is a quadrilateral with two pairs of parallel sides. That means that  the only way to have a paralellogram is to have a quadrilateral with two pairs of parallel sides. If we have a quadrilateral with only one pair of parallel sides, then it is not a parallelogram.

This translates to the following statement "a quadrilateral is a parallelogram if and only if it has two pairs of parallel sides". Meaning that if we have a parallelogram we know we have a quadrilateral with two pairs of parallel sides and if we have a quadrilateral with two pairs of parallel sides we have a parallelogram.

Answer:

A) Predicted value: 13.1   Residual: 0.9

Step-by-step explanation:

By definition:

residual = observed - predicted

The linear model is:

f(x) = 1.3x + 9.2

where f(x) is the height and x is the age of the tree.

Replacing with x = 3:

f(x) = 1.3(3) + 9.2 = 13.1 ft

which is the predicted value. The observed value is 14 ft, then:

residual = 14 - 13.1 = 0.9 ft

Merek got the correct sum, but her decomposition of 347 is incorrect.

Arithmetic is a branch of mathematics that deals with the study of numbers, their properties, and their operations. It involves the basic operations of addition, subtraction, multiplication, and division.

Here,
Merek's mistake is that she incorrectly decomposed the two-digit numbers 47 into 40 and 7 instead of 30 and 17.

To add 260 and 347, we can align the digits vertically:

 260

+ 347

-----

 607

So, the sum is 607.

Merek decomposed 347 as 300 + 40 + 7, which gives:

 260

+ 300

+  40

+   7

-----

 607

So, Merek got the correct sum, but her decomposition of 347 is incorrect. She should have decomposed 347 as 300 + 40 + 7, or as 300 + 30 + 17, instead of 300 + 40 + 7.

Step-by-step explanation:

credit means that you can buy anything you want but your not spending your money but eventually you will have to pay it back

so she can use the dishwasher while paying for it over a period of time and she can buy the dishwasher even if she doesn't have the money now to pay for it.

if she pays it with cash then she's using her money with the credit you have to pay it over time and if you don't pay the credit you will be in BIGG trouble so pay it!!

hope it helped!! :D

She can receive a discount on the price if she uses credit instead of paying cash. She can buy the dishwasher even if she doesn't have the money now to pay for it. Hence, Option A and C are the correct options.

A loan is a form of credit where a lender allows another party (the borrower) the use of money or property for a specified period of time.

Why does credit that offers long-term advantages exist?

If those conditions are met, a long-term loan can reduce the impact on operational cash flow, allow a debtor to borrow at a lower interest rate, reduce investor interference, and assist a business in establishing its credit worthiness.

Short-term loans are thus preferred for working capital, such as payroll, inventory, and seasonal imbalances, whereas long-term loans are typically used to purchase fixed assets, such as equipment.

Credit cards are more widely accepted and, in general, faster to use than checks. Bill payments via credit card can be made automatically, combining multiple payments into a single one.

By using a credit card with a rewards programme, you could earn rewards such as free travel.
