Answer:

$8.80

Step-by-step explanation:

In order to find the new price, you need to add 60% of the original price (5.50) to the original price. You have two options:

1) multiply $5.50*0.6 to get 60% of the original price. You would get $3.30. Then add $3.30+$5.50, which equals $8.80. This way takes longer but shows you all the steps.

2) The shorter way is to simply multiply $5.50*1.6, which also equals $8.80. This works because the "1" automatically adds the 5.50 to 60% of the original price, this way you don't have to multiply then add.

If you don't understand how the second way works or your teacher taught you #1, just do it the first way.

What is the product of 2x+ 3 and 4x2 - 5x+ 6?

elena-s [515]

Answer:

8x³ - 25x² - 3x + 18

Step-by-step explanation:

(2x + 3)(4x²- 5x + 6)

multiply 2x by each of the three terms in the second expression to get:

8x³ - 10x² + 12x

now multiply 3 by each of the three terms in the second expression to get:

12x² - 15x + 18

Combine 'like terms': -10x² + (-15x²) = -25x²

Combine 'like terms': 12x + (-15x) = -3x

Put all terms in decreasing exponent order:

8x³ - 25x² - 3x + 18

If the relation is a function, list the domain and range. If the relation is not a function, choose "not a function". C = {(9, 1

ICE Princess25 [194]

Answer:

<h2>Domain: {9, 8, 7, -5}</h2><h2>Range: {1, -3, 5, 3}</h2>

Step-by-step explanation:

The function is a special relationship where each input has a single output.

We have C = {(9, 1); (8, -3); (7, 5); (-5, 3)}.

It's a function:

each values of x: 9, 8, 7, -5 has one value of y: 1, -3, 5, 3.

The doimain is set os x: {9, 8, 7, -5}.

The range is set of y: { 1, -3, 5, 3}.

I rlly need some help please if ur big brains im going to be asking multiple questions right now

Lynna [10]

You can break the shape up into a rectangle and a right triangle.

Use your trig ratios to find the missing sides.

Add all the sides up and you have your perimeter!

$p = 2(l) + 2(w)$

$p = 2(10) + 2(4)$

$p = 28$

$tan = \frac{opp}{adj}$

$\tan(45) = \frac{10}{adj}$

$adj = \frac{10}{ \tan(45) }$

$adj = 10$

${a}^{2} + {b}^{2} = {c}^{2}$

${10}^{2} + 10 {}^{2} = {200}^{2}$

$\sqrt{200} = 14.14213562$

$p = 10 + 4 + (4 + 10) + 14.14213562$

<em>*notice how one of the 10 is left out because it is inside the shape so we can't use that to find perimeter.</em>

$p = 42.14$

Find the product and write in lowest term. Give me an integer or simplified fraction.<br> 7/54×27/35

wariber [46]

The product of given expression is $\frac{1}{15} \text{ or } 0.0667$

<em><u>Solution:</u></em>

Given that we have to find the product and write it in lowest term

Given expression is:

$\frac{7}{54} \times \frac{27}{35}$

Let us first find common factors of numerator and denominator so, thet simplification becomes easier

$54 = 27 \times 3\\\\35 = 7 \times 5$

Substituting these in above expression, we get

$\rightarrow \frac{7}{27 \times 3} \times \frac{27}{7 \times 5}$

Cancel the common factors in numerator and denominator

$\rightarrow \frac{1}{15}$

In decimal form, we get

$\rightarrow \frac{1}{15} = 0.0667$

Thus the product of given expression is $\frac{1}{15} \text{ or } 0.0667$
