Answer:

a=  n+6  n

Step-by-step explanation:

n=an−1−5

Step 1: Flip the equation.

an−6=n

Step 2: Add 6 to both sides.

an−6+6=n+6

an=n+6

Step 3: Divide both sides by n.

an  n  =  n+6  n  a=  n+6  n

A conversion table indicates that 1 mile is 1.6 km. With this conversion rate, is the speed limit greater than or less than 65 mph? Explain.

Answers

greater because 1.6 is larger than 1

Answer:

higher than

Step-by-step explanation:

The speed limit is 110 km hour and there are 1.6 kilometers in a mile. This means that there are 110 ÷ 1.6 miles per hour:

110 km hour÷1.6 km mile=110÷1.6 miles hour.

We can find 110 ÷ 1.6 using long division and it is 68.75. So the speed limit  is higher than 65 mph

Explain how compound interest is better than simple interest when it comes to saving money.

Answers

Answer:

With compound interest, you earn interest on interest, thereby accumulating more money than if you were earning simple interest.

Step-by-step explanation:

Answer: Compound interest keeps adding small amounts of interest as often as the given time period states. If monthly, for example, 1/12 of the annual rate is added to the principal at the end of the first month. Then the next month, the interest is figured on the new higher amount. Each month the principal grows a little instead of waiting until a year has passed to compute the interest on just the original principal.

What is the y-intercept in the equation y=4x-3?

Answers

Answer:

-3

Step-by-step explanation:

y = mx +b

mx = slope

b = y intercept

hope this helps!

Answer:

-3

Step-by-step explanation:

The y intercept (when already written in slope-intercept form) is on the side of the equation without the actual variable y. The number with x is the slope. In this specific equation, the slope is 4 because it is with the variable x, and the y intercept is the other number, -3. The 3 is negative because subtraction signs are actually negative signs too.

Hope this helps!! Have a great day ^^

Jacob sells homemade skateboard decks for a profit of $27 per each one. He is considering switching to a new type of material that will increase his profit (y = 32x0) (where x is the number sold and y is the amount of profit).

How many more dollars will Jacob earn on each skateboard deck if he switches to the new material?
(Please Explain)

Answers

Answer:

I believe it is 32

Step-by-step explanation:

I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do.. 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32

Jacob will earn more for each skateboard deck if he switches to the new material is $5.

What is profit?

When something or the cost of manufacturing an object is less than the selling price of the object, then you get a profit.

As it is given that Jacob will increase his profit by 32x where x is the number sold means he will get $32 if he sold one product (32×1).

Before, he gets  a profit of $27 if he sold one skateboard, so,

Let Jacob will earn y amount more than the current material,

y = Profit in new material - Profit in old material

y = 32 - 27

y = $5

Therefore, Jacob will earn more for each skateboard deck if he switches to the new material is $5.

For there lay The Combs--the set of combs, side and back, that Della had worshipped long in a Broadway window. Beautiful combs, pure tortoise shell, with jewelled rims--just the shade to wear in the beautiful vanished hair. They were expensive combs, she knew, and her heart had simply craved and yearned over them without the least hope of possession. And now, they were hers, but the tresses that should have adorned the coveted adornments were gone. But she hugged them to her bosom, and at length she was able to look up with dim eyes and a smile and say: "My hair grows so fast, Jim! And them Della leaped up like a little singed cat and cried, "Oh, oh!" Jim had not yet seen his beautiful present. She held it out to him eagerly upon her open palm. The dull precious metal seemed to flash with a reflection of her bright and ardent spirit."Isn't it a dandy, Jim? I hunted all over town to find it. You'll have to look at the time a hundred times a day now. Give me your watch. I want to see how it looks on it." Instead of obeying, Jim tumbled down on the couch and put his hands under the back of his head and smiled."Della," said he, "let's put our Christmas presents away and keep 'em a while. They're too nice to use just at present. I sold the watch to get the money to buy your combs. And now suppose you put the chops on." The magi, as you know, were wise men--wonderfully wise men--who brought gifts to the Babe in the manger. They invented the art of giving Christmas presents. Being wise, their gifts were no doubt wise ones, possibly bearing the privilege of exchange in case of duplication. And here I have lamely related to you the uneventful chronicle of two foolish children in a flat who most unwisely sacrificed for each other the greatest treasures of their house. But in a last word to the wise of these days let it be said that of all who give gifts these two were the wisest. O all who give and receive gifts, such as they are wisest. Everywhere they are wisest. They are the magi. What type of irony is most evident in the excerpt above?
