What is the product of (2x – 1)
(3x + 3)?

Answers

Answer:

6x^2 + 3x - 3

Step-by-step explanation:

Using the FOIL method, we would multiply 2x by 3x, then multiply 2x by 3, then multiply -1 by 3x, then multiply -1 by 3. This would bring the answer to 6x^2 + 6x -3x - 3. Combine the like terms 6x and -3x and you get 6x^2 + 3x - 3

ach light bulb at Hotel California is either incandescent or fluorescent. At a certain moment, forty percent of the incandescent bulbs are switched on, and ninety percent of the fluorescent bulbs are switched on. If eighty percent of all the bulbs are switched on at this moment, what percent of the bulbs that are switched on are incandescent

Answers

Answer:

10%

Step-by-step explanation:

The computation of the percentage of bulbs that switched on incandescent is as follows;

Let us assume the incandescent be I

And, the fluorescent be F

Now the equation is

0.4I + 0.9F = 0.8 (I+F)

0.41I + 0.9F = 0.8I + 0.8F

So here

0.4I = 0.1F

Now the percentage would be for incandescent in the case of switched on is

= 0.4I ÷  0.8(I+F) × 100

= 0.1F ÷ 1F

= 10%

What polynomial should be subtracted from 3x^2+4x-1 to get the difference equal to 1

Answers

Answer:  3x^2+4x-2

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

Explanation:

Assume the polynomial we want to find is in the form Ax^2+Bx+C

The goal is to find the values of A, B, and C.

We start with 3x^2+4x-1, then we subtract off Ax^2+Bx+C. Set this equal to 1 and we get:

(3x^2+4x-1) - (Ax^2+Bx+C) = 1

3x^2+4x-1 -Ax^2-Bx-C = 0x^2 + 0x + 1

(3x^2-Ax^2) + (4x-Bx) + (-1-C) = 0x^2 + 0x + 1

(3-A)x^2 + (4-B)x + (-1-C) = 0x^2 + 0x + 1

From here we equate the coefficients of the x^2 terms together and we see that 3-A = 0 which leads to A = 3.

Do the same for the x terms to get 4-B = 0 leading to B = 4

Finally, we have -1-C = 1 lead to C = -2

The polynomial Ax^2+Bx+C becomes 3x^2+4x-2

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

Checking the answer:

(3x^2+4x-1) - (Ax^2+Bx+C)

(3x^2+4x-1) - (3x^2+4x-2)

3x^2+4x-1 - 3x^2-4x+2

(3x^2-3x^2) + (4x-4x) + (-1+2)

0x^2 + 0x + 1

0 + 0 + 1

1

We get a difference of 1, so the answer is confirmed.

One hour after a hiker left camp, a biker set out to catch up. If the hiker traveled 3 miles per hour and the biker traveled 6 miles per hour faster, how long will it take for the biker to catch up with the hiker?

Answers

Answer:

30 minutes after biker left

Step-by-step explanation:

Given that :

Speed of hiker = 3 mph

Speed of biker = (3 +6) = 9 mph

Present Distance of hiker when the biker set out ;

Present Distance of hiker = speed * time = (3 * 1) = 3 miles

Time taken to catchup equals :

Present distance + (distance when biker set out) = bikers distance

Let time taken = x

(3 + (3 * x)) = (9 *x)

(3 + 3x) = 9x

3 + 3x = 9x

3 = 9x - 3x

3 = 6x

x = 3/6

x = 1/2 hours

x = 30 minutes

Answers

Answer:

x = 8

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

5(x - 2) - 6 = 24

Step 2: Solve for x

Add 6 to both sides:                    5(x - 2) = 30Divide 5 on both sides:                x - 2 = 6Add 2 to both sides:                    x = 8

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    5(8 - 2) - 6 = 24Subtract:                              5(6) - 6 = 24Multiply:                               30 - 6 = 24Subtract:                              24 = 24

Here we see that 24 does indeed equal 24.

∴ x = 8 is the solution to the equation.

Step-by-step explanation:

m∠X + m∠Y + m∠Z = 180          {angle sum  property of triangle}

3x + 5 + 40 +4x - 5 = 180

3x + 4x  + 5 + 40 -5 = 180           {Combine like terms}

                   7x + 40 = 180        { subtract 40 from both sides}

                            7x = 180 - 40

                            7x = 140

                             x = 140/7

                            x = 20

m∠X = 3x + 5

         = 3*20 + 5

         = 60 + 5

m∠X = 65

m∠Z = 4x - 5

         = 4*20 - 5

        = 80 - 5

m∠Z = 75

Jack is trying to make extra money on his summer vacation from school. He works two different jobs, earning $9 per hour washing cars and $6 per hour walking dogs.

How much money would Jack earn in a week in which he worked w w hours washing cars and d d hours walking dogs? 5 hours washing cars and 2 hours walking dogs: w w hours washing cars and d d hours walking dogs:

Answers

Answer:

$57

[tex]9w+6d[/tex]

Step-by-step explanation:

Given that:

Earnings per hour for washing cars = $9

Earnings per hour for walking dogs = $6

Number of hours for which car washing is done = [tex]w[/tex]

Number of hours taken for walking dogs = [tex]d[/tex]

Earnings for [tex]w[/tex] hours for washing cars = Per hour earnings multiplied by number of hours = $9[tex]w[/tex]

Earnings for [tex]d[/tex] hours for walking dogs = Per hour earnings multiplied by number of hours = $6[tex]d[/tex]

Total earnings by both = $([tex]9w+6d[/tex])

Now, given that

Number of hours spent washing cars = 5 hours

Number of hours spent walking dogs = 2 hours

Therefore, total earnings by both = 9 [tex]\times[/tex] 5 + 6 [tex]\times[/tex] 2 = $57

Set the two equations 13x+34 and 10x+10 together to add up to 90 on the right which should look like this 13x + 34 + 10x + 10 = 90.  Combine the two x-values to get 23x and the two other numbers to get 44.  Your equation should now be 23x + 44 = 90.  Subtract 44 on both sides to get this equation 23x = 46.  Divide 23 on both sides to get your x value which is 2.

Answer:

X is equal to 2

Step-by-step explanation:

90 = 13x + 34 + 10x + 10

Combine Like Terms:

90 = 23x + 44

Subtraction Property of Equality:

90 - 44 = 23x + 44 - 44 ---> 46 = 23x

Division Property of Equality:

46 ÷ 23 = 23x ÷ 23 ---> 2 = x

Check Your Work:

90 = 13x + 34 + 10x + 10

Fill In Variables:

90 = 13(2) + 34 + 10(2) + 10

90= 26 + 34 + 20 + 10

90 = 60 + 30

Answers

Answer:

16 cups is equal to 4 quarts

Step-by-step explanation:

Multiply the volume by 4

The required  4 quarts are equal to 16 cups. This means that if you have 4 quarts of liquid, you can pour it into 16 cups and it will completely fill them. Option D is correct.

1 quart is equivalent to 4 cups. This is a standard conversion ratio between quarts and cups. It means that if you have 1 quart of liquid and you want to know how many cups it is, you can simply multiply the number of quarts by 4.

So, to find out how many cups are in 4 quarts, we perform the following calculation:

4 quarts * 4 cups/quart = 16 cups

What is an equation of the line that passes through the point (8,-7)(8,−7) and is parallel to the line 5x+4y=165x+4y=16?

Answers

Answer:

The equation of line parallel to given line passing through (8,-7) is:

[tex]y = -\frac{5}{4}x+3[/tex]

Step-by-step explanation:

Given line is:

5x+4y=16

first of all, we have to convert the equation of given line in slope-intercept form

[tex]4y = -5x+16[/tex]

Dividing both sides by 4

[tex]\frac{4y}{4} = -\frac{5x}{4} + \frac{16}{4}\\y = -\frac{5}{4}x+4[/tex]

Slope intercept form is:

[tex]y=mx+b[/tex]

The slope of given line is:

[tex]m = -\frac{5}{4}[/tex]

Let m1 be the slope of line parallel to given line

"The slopes of two parallel lines are equal"

[tex]m = m_1\\m_1 = -\frac{5}{4}[/tex]

The equation of line parallel to given line will be:

[tex]y = m_1x+b[/tex]

Putting the value of slope

[tex]y = -\frac{5}{4}x+b[/tex]

Putting the point (8,-7) in the equation

[tex]-7 = -\frac{5}{4}(8)+b\\-7 = -(5)(2) + b\\-7 = -10+b\\b = -7 +10\\b = 3[/tex]

Putting the value of b

[tex]y = -\frac{5}{4}x+3[/tex]

Hence,

The equation of line parallel to given line passing through (8,-7) is:

[tex]y = -\frac{5}{4}x+3[/tex]

In ΔQRS, r = 380 cm, s = 390 cm and ∠Q=48°. Find the length of q, to the nearest centimeter.

Answers

Step-by-step explanation:

Using Cosine rule, we have:

q² = r² + s² - 2(r)(s)(cosQ)

= 380² + 390² - 2(380)(390)(cos48°)

= 98169.688cm²

Hence q = 313cm. (nearest centimeter)

The required value of side q is 313 cm for the triangle ΔQRS.

What is a triangle?

A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.

The sum of the angles of a triangle is always 180°

Given that,

In triangle QRS side r = 380 cm, side s = 390 cm and angle Q = 48°.

To find the length of the side q,

Use cosine rule,

[tex]cos Q = \frac{(r^2 + s^2 - q^2)}{(2\times r \times s)}[/tex]

Substitute the values here,

[tex]cos 48 = \frac{(380)^2 + (390)^2- q^2}{2\times380 \times390} \\[/tex]

[tex]0.67 = \frac{144400 + 152100 - q^2}{296400}[/tex]

198,588 = 296500 - q²

q² = 97912

q = 312.90

q = 313 cm

The value of side q is 313 cm.
