Answer:

Part A: 31000 + 3000x = 38000 + 2000x; Part B: 7 years.

Step-by-step explanation:

x = number of years since start

For Company A, we have that salaryA(x) = 31000+3000x,

For Company Part B: salaryB(x) = 38000+2000x

We want x such that salaryA(x) = salaryB(x).

Thus,

31000 + 3000x = 38000 + 2000x (Answer to part A)

Subtracting 31000 from both sides of the equation implies that:

3000x = 7000 + 2000x.

Subtracting 2000x from both sides implies that:

1000x = 7000.

Then, dividing both sides of the equation by 1000 yields:

x = 7 years (Answer to part B)

Answer: 2.5 feet

Step-by-step explanation:

A 30-60-90 triangle is a special right triangle in which the sides all have a fixed relationship with each other.  We only need to know one side to calculate the other two.

Make the side opposite the 30° angle x, then

The side opposite the right angle is 5ft, therefore:

2x = 5

x = 2.5ft, the side opposite the 30° angle

Then x*√3 is the third side:

(2.5)*(1.442) = 3.605 feet

Answer:

y = -5/2x + 5

Step-by-step explanation:

slope intercept form: y = mx + b

5x + 2y = 10 ------- subtract 5x on both sides

2y = -5x + 10 ------- divide 2 on both sides

y = -5/2x + 5

Answer:

-7/4

Answer:

(−3)(2^2−+3)

Step-by-step explanation:

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.

To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Answer: you answer is

Step-by-step explanation:

Find the slope of the parallel line

(7, 2) and is parallel to y= -2x+1?

When two lines are parallel, they have the same slope.  

                ⇒  if the slope of the given line is = - 2      

                     then the slope of the parallel line (m) = - 2

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  

                              ⇒  y - 2  =  - 2 (x - 7)                                  

We can therefore write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:  

                     since   y - 2  = - 2 (x - 7)  

Answer:

81% of the balls are red

Step-by-step explanation:

If you want to find the percentage of balls that are red you will have to divide it by the total number of balls in the ball

18 red + 4 blue = 22 balls  part (a)

18/22 = 9/11   part (b) simplify

9/11 * 100     part (c) multiply the fraction by a hundred to get the percentage

81.81 ~ 81%  part (d) solve

Answer:

81 9/11%

Step-by-step explanation:

First add the number of red and blue balls together. 18 + 4 = 22

What is the number of red balls? It’s 18

We have to begin by writing this information as a fraction. 18 balls would be the numerator and the total of red and blue balls together, 22 will be the denominato. Now, we have the fraction, 18 (red) / 22 (total). To find the percentage, divide the numerator by the denominator. 18 divided by 22, which is 9/11. Now multiply 9/11 by 100, which gives you 81 9/11%.

Therefore, the answer is 81 9/11%.

Answer:

x = (v-w)/k

Step-by-step explanation:

Step 1: Isolate x by dividing both sides of the equation by k.

Therefore, the answer is [tex]x = \frac{v-w}{k}[/tex].

Answer:

x = [tex]\frac{v-w}{k}[/tex]

Step-by-step explanation:

xk = v - w ( isolate x by dividing both sides by k )

x = [tex]\frac{v-w}{k}[/tex]

Answer:

x = 1,213

y = 1,314

z = 714

Step-by-step explanation:

$10 = x

$20 = y

$30 = z

10x + 20y + 30z = 59,830

____________

Solving for x:

Since there 101 more $20 tickets than $10 tickets we are making the equation of:

y = x + 101

First equation (substitute the equation above for y)

x + (x+ 101) + z = 3,241

Subtract 101 from 3,241

2x + z = 3,140

Second equation (substitute y with 'x + 101 ')

10x + 20(x + 101) + 30z = 59,830

10x + 20x + 2,020 + 30z = 59,830

Subtract 2,020 from 59,830

10x + 20x + 30z = 57,810

Add 10x and 20x

30x + 30z = 57,810

Cancel out the 30's and divide 57,810 by 30

x + z = 1,927

Now solve using the first 2 equations

2x - z =3,140 = x + z = 1,927

Subtract z

2x = 3,140 = x + 1,927

Divide x

x = 3,140 = 1,927

Subtract 1,927 from 3,140

x = 1,213

____________________

Solving for y:

y = x + 101

y + 1,213 + 101

y = 1,314

____________________

Solving for z:

1,213 + 1,314 + z = 3,241 (Overall tickets sold)

2,527 + z = 3,241

Subtract 2,527 from 3,241

z = 714

____________________

Check math:

10x + 20y + 30z = 59,830

10(1,213) + 20(1,314) + 30(714) = 59,830

y =-2x+3

Answer:

11

Step-by-step explanation:

1.80m + 0.6s = 12.00

[substitute the value of m into the equation]

1.80×(3) + 0.6s = 12

5.4 + 0.6s = 12

[make s the subject of the formula]

0.6s = 12 - 5.4

0.6s = 6.6

[divide both sides of the equation by 0.6]

0.6s / 0.6 = 6.6 / 0.6

s = 11

To prove that 11 is correct

[substitute the value of m and s into the equation]

1.80m + 0.6m = 12.00

1.80×(3) + 0.6×(11) = 12.00

5.4 + 6.6 = 12.00

12.00 = 12.00

natasha.............4550/70=65..................................

krutika................2400/40=60...............................

so the answer is A

Step-by-step explanation:

Answer:

A) Caroline

Step-by-step explanation:

To find this, simply divide the amount of words they type by the amount of minutes they type:

To solve Caroline's do:

3500/50=70

Caroline types 70 words per minute.

To solve Natasha's do:

4550/70=65

Natasha types 65 words per minute.

To solve Krutika's do:

2400/40=60

Krutika types 60 words per minute.

Since Caroline has the highest wpm, we can safely say that Caroline types the fastest rate of words per minute.

Answer:

10010110 . 100011₂

Step-by-step explanation:

A real number consists of two parts.

That is, ( 1 ) Integer part     ( 2 ) fractional part

Let us take the given number as an example.

Here, 150 . 55 ←  fractional part

           ↑        

(integer part)

So, to make such a decimal number into a binary number you have to use a method like this.

Let us solve it now.

Integer part

2 |150  

2 |75    - 0

2 | 37   - 1

2 | 18     - 1

2 | 9      - 0

2 | 4       - 1

2 | 2       - 0

2 | 1         - 0

    0         - 1

∴ 150 ⇒ 10010110₂

Fractional part

   | . 55 × 2

 1 | . 10 × 2

0 | . 2 × 2

0 | . 4 × 2

0 | . 8 × 2

 1 | . 6 × 2

 1 | . 2

As this fractional part not getting the zero even we multiply by 2 continuously, we have to write an approximate value for this.

150.55 ⇒ 10010110 . 100011₂
