Answer:

-4j + 3 or 3 - 4j

Step-by-step explanation:

you can combine the terms in any order that you want, but i'm going to begin with the j terms.

first, identify the like terms.

-6j + 4 + 2j - 1

then combine the like terms.

-6j + 2j = -4j

now identify the next set of like terms.

-6j + 4 + 2j - 1

combine those like terms.

4 - 1 = 3

after combining the first set of like terms, you're left with: -4j

after combining the second set of like terms, you're left with: 3

therefore the simplified expression is -4j + 3 or 3 - 4j. rearranging those terms doesn't change the answer, so it doesn't matter what order you write it in.

i hope this helps!! have a great rest of your day :)

Answer:

Step-by-step explanation:

$6/(2 DVDs) = $3/DVD, and $8/(4 CDs) = $2/CD

a DVD costs $3

a CD costs $2

Lynn bought 4 DVDs and 2 CDs for 4×$3 + 2×$2 = $16.

Pierre bought d DVDs and c CDs for $20.

d is 0, 2, 4, or 6

c = (20-3d)/2

(d,c) = (0,10), (2,7), (4,4), or (6,1)

Answer:

  6.2 ft

Step-by-step explanation:

The volume of a cylinder is given by ...

  V = πr²h

Here, we have r=2h and V=3000 ft³. Putting these numbers into the formula and solving for h, we get ...

  3000 ft³ = π(2h)²h

  (3000 ft³)/(4π) = h³ . . . . . divide by the coefficient of h³

  h = ∛(750/π) ft ≈ 6.2 ft

The pool is about 6.2 feet deep.

Answer:

12%

Step-by-step explanation:

Answer:

Step-by-step explanation:

x% of 3.50 = 12.50

x% = 12.50/3.50 ≅ 3.57 = 357%

price increased by 357%

profit = 12.50 - 3.50 = $9

Answer:

Im pretty sure you need to multiply answer is 10

Step-by-step explanation:

because the -5and -2 are right next to each other and if -7 doesn't work thats the next best thing.

Answer:

1. 170/490 and 60/505

2. 320/490 and 445/505

Step-by-step explanation:

No options were given, but the question can still be answered

Given

[tex]\begin{array}{cccc}{} & {\ge 1\ tattoo} & {0\ tattoo} & {Row\ Total} & {18 -29} & {170} & {320} & {490} & {30 - 50} & {60} & {445} & {505} & {Column\ Total} & {230} & {765} & {995}\ \end{array}[/tex]

Required

Which proportion best compares age and tattoos?

The row data represents the age range of each group while the column data represents the amount of tattoo by each group.

So, to make comparison:

You simply pick a cell data and compare it to the row total.

Take for instance

For those who have at least 1 tattoo. The proportion to use are:

170/490 --- For age range: 18 - 29

60/505 --- For age range: 30 - 29

For those without tattoo. The proportion to use are:

320/490 --- For age range: 18 - 29

445/505 --- For age range: 30 - 29

Answer:

x = 22.1°

Step-by-step explanation:

Angle ∠A = 41.124° = 41°7'26" = 0.71775 rad

Angle ∠B = 22.075° = 22°4'31" = 0.38528 rad

Angle ∠C = 116.801° = 116°48'4" = 2.03856 rad

Answer:

I think it is A that will take longer but im not 100 percent sure

Step-by-step explanation:

First write an equation:

Location A-   800+100x

Location B-  1200+200x

Then you need to plug numbers in for x

Answer:

(A) 490ft.

(B) 2.8 miles

Step-by-step explanation:

Important points to note:

- The limestone layer is thought or assumed to slope downward in a straight line.

- 2 miles west of Seiling, the limestone layer was found at a depth of 220ft.

- 3 miles west of Seiling, the limestone layer was found at a depth of 270ft.

(A) What would you expect to be the depth of the limestone layer, 5 miles west of Seiling?

The expected depth of the limestone layer is:

2 miles + 3 miles = 5 miles

220ft + 270ft = 490ft

(B) Your budget will allow you drill a well that is 275ft deep. How far west of Seiling (in miles) can you go, to drill the well?

If 490ft  ~  5 miles

then 275ft  ~  K miles

K = [275 x 5] / 490  = 2.80612245 miles

Rounding to 1 decimal place, the distance is 2.8 miles.

Answer:

c.

1500

Step-by-step explanation:

The computation of the total amount of interest in first month is shown below:

Interest for first month is

= Mortgage amount × interest rate ÷ total number of months in a year

= $300,000 × 6% ÷ 12  

= $1,500

Hence, the interest in the first month is $1,500

Therefore the c option is correct

Answer:

1.67square foot/hr

Step-by-step explanation:

If a fertilizer covers 5/6 square foot in 1/2 hour, then;

5/6 square foot  = 1/2 hour

To determine the unit rate, we will say;

x square foot = 1 hr

Divide both expressions

5/6x = 1/2

5 * 2 = 6x

10 = 6x

x = 10/6

x = 1.67square foot/hr

Hence the unit rate is 1.67square foot/hr

Answer: C.concurrent power

Step-by-step explanation: Such powers are called concurrent powers. These include the power to tax, spend, and borrow money. State governments operate their own judicial systems, charter corporations, provide public education, and regulate property rights.

Answer: 15

Step-by-step explanation:

The 11th term of arithmetic progression is 43. We can use this to get the common difference which will be:

a + (n - 1)d = 43

where,

a = first term = 3

n = nth term = 11

d = common difference = unknown

Therefore, a + (n - 1)d = 43

3 + (11 - 1)d = 43

3 + 10d = 43

10d = 43 - 3

10d = 40

d = 40/10

d = 4

Common difference = 4

Therefore, 4th term will be:

= a + (n - 1)d

= a + (4-1)d

= a + 3d

= 3 + 3(4)

= 3 + 12

= 15

The 4th term is 15

Step-by-step explanation:

substitute the given value in the standard form equation. it will give you the slope intercept form

The area of a circle is:

Area = PI x r^2 ( r is the radius which is half the diameter)

Using the information in the problem:

254.34 = 3.14 x r^2

Divide both sides by 3.14:

81 = r^2

Take the square root of both sides:

r = 9

The diameter = 2r = 2(9) = 18 cm

Answer:

-5<n≤2

Step-by-step explanation:

Divide 3 by -15 nad 6 since we need to find the "n" we need to divide on all sides, so -15 divided by 3 is -5 so replace -15 with -5 and 6 divided by 3 is 2 so replace 6 with 2
