Which polynomials are in standard form?

Mathematics
1 answer:
pickupchik [31]2 years ago
3 0

Answer:

A and C are the correct answers.

Step-by-step explanation:

Monomials without a variable go after the monomials with a variable. Variables with high exponents go first. A and C both show those.

  • In choice A, since 3z has a variable, it goes before 1.
  • In choice C, since -5p^5 has the highest exponent it does go first.
  • Then 2p^2, since it has the second highest exponent.
  • Then -3p follows, with the lower exponent.
  • Then 1 goes last because it has no variable and has the lowest exponent.

Marisa decided to raise the price of her earrings so that she will make a profit of $5.00 on each pair. She has
Varvara68 [4.7K]

Marisa, who raise the price of her earrings so that she will make a profit of $5.00 on each pair, expect to make a profit with her company.

<h3>What is the unit price?</h3>

The unit price is the amount of money required to buy one unit of a item or goods.

To find the unit price, divide the total cost of the goods to the total number of goods.

The cost of repair will now be $60. Thus, the total cost of 50 earrings is,

C=60\times50\\C=3000

Marisa decided to raise the price of her earrings so that she will make a profit of $5.00 on each pair. Thus, the new selling price of her earring is,

P=60+5\\P=65

The sale's price of 50 earrings is,

P=50\times65\\P=3250

She has also improved the quality control so that only 1 pair in 50 need to be returned for repair. Thus, the cost price of one earring has to be removed from the sales price of 50 earrings as,

P=3250-60\\P=3190

The profit made by her company on 50 earrings is

p=P-C\\p=3190-3000\\p=190

Thus, Marisa, who raise the price of her earrings so that she will make a profit of $5.00 on each pair, expect to make a profit with her company.

In triangle ABC one side equal  and two sides equal  

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

AC is face diagonal of front face.

BC is face diagonal of right face.

AC=BC≠AB

Hence, In triangle ABC one side equal  and two side equal  

Hope this helps!!
