Answer:

B

Step-by-step explanation:

6% of her salary is  .06 * 50000 = 3000  <===== matched 100%

   from 6- 12% is another 3000 <=====matched 50% =  1500

3000 + 1500 = 4500 dollars matched

(she put in 6000 and her employer put in 4500 = 10500 total)

The value of   Matrix B = [tex]\left[\begin{array}{ccc}9&17&3\\2&17&0\\3&22&8\end{array}\right][/tex]

Given : Matrix A = Matrix B

matrix A=      [tex]\left[\begin{array}{ccc}9&-2&3\\2&17&0\\3&22&8\end{array}\right][/tex]

The matrix A=      [tex]\left[\begin{array}{ccc}9&-2&3\\2&17&0\\3&22&8\end{array}\right][/tex] (according to the question)

Since it is given A=B

and substituting the given values of elements of B

matrix B=[tex]\left[\begin{array}{ccc}9&17&?\\?&?&?\\?&?&?\end{array}\right][/tex]

According to the property of equality of matrices,

When the matrices are given to be equal, their corresponding elements are also equal

so

b13 = 3

b21 = 2

b22 = 17

b23 = 0

b31 = 3

b32 = 22

b33 =8

Substituting the found out values in place of the question marks,

Answer:

Step-by-step explanation:

The domain of the function will be (-∞, ∞) and the range of the function will be (-∞, ∞).

The domain means all the possible values of x and the range means all the possible values of y.

The set of ordered pairs is given below.

{(-3, 2), (-2, 1), (-1,0), (0, -1)}

Then the line function will be

    y – 0 = [(– 1 – 0)/(0 + 1)] (x + 1)

          y = – x – 1

x + y + 1 = 0

Then the domain of the function will be (-∞, ∞) and the range of the function will be (-∞, ∞).

The number of feet of fencing that is needed to go around the pool path is D. 201 ft.

We have a pool with a radius of 28 feet. The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.

= (28 + 4) feet

= 32 feet

The circumference of the outer edge of the pool path would be equal to the perimeter.

p = 2 * pi * r

p = 2 * 3.14 * 32

p = 200.96 feet

p = 201 feet

Answer:

24

Step-by-step explanation:

The interquartile range defines the difference between the third and the first quartile.

Let's put this data set in ascending order:

24, 36, 48, 52, 52, 60, 72

The median is 52. The median of both the lower (1st quartile) and upper half (3rd quartile) of the data is 36 and 60.

Now we can subtract the first quartile from the third quartile (60 - 36) to get the interquartile range of 24.

Step-by-step explanation:

The prices are inconsistent, so there is no unique price that can be set for either an apple or an orange that will give the total prices indicated.

__

The first relation can be written as ...

  $10 = 4A +4O

  $10 = 4(A +O) . . . . factor out 4

  $2.50 = A +O . . . . divide by 4

The second relation can be written as ...

  $12 = 6A +6O

  $12 = 6(A +O) . . . . factor out 6

  $2 = A +O . . . . . . . divide by 6

These two relations give different prices for 1 apple and 1 orange. There is no price that can be set for either fruit that will give this result.

No unique prices can be assigned.

Answer:

(10, 14)

Step-by-step explanation:

Hello there!

Given such a problem, we have been told to use substitution method to solve it.

To cut it short, substitution refers to replacing a variable with a value.

Here is a way to solve this problem even in future:

Back to our problem,

y = 2x - 6, x = 10

Substitute x into equation y = 2x - 6

y = 2(10) - 6

= 20 - 6

= 14

. ° . x = 10, y = 14

Variables in terms of x and y

(x, y) = (10,14) ✓

This is our answer.

I hope this helps.

Answer:

True

Step-by-step explanation:

8-2 (i+1) < 12 − 7i + 4i

Left side of the inequality:

8 - 2(i + 1)        distribute

8 - 2i - 2        simplify

(8 - 2) - 2i

6 - 2i

Right side of the inequality:

12 − 7i + 4i        simplify

12 − 3i

Combine:

6 - 2i < 12 − 3i

6 is less than 12

3i is less than 2i

leads to the assumption that the statement is true

The distributive law is satisfied if the numbers 1,2, and 3 are used as multyplying factors.

Answer:

hi the answer is c

Step-by-step explanation:

The type of variation between the speed and time is inverse.

The equation is r = d / t

The number of miles travelled is 102 miles.

When the speed a person is driving at increases, the time it takes to travel would decrease. On the hand,  speed a person is driving at decreases, the time it takes to travel would increase. This means that there is an inverse relationship.

The equation that represents an inverse relationship is

r = d / t

Where d is the distance

By the geometric mean theorem, [tex]\frac{x}[6} =\frac{6}{4} \longrightarrow x=\left(\frac{6}{4} \right)(6)=\boxed{9}[/tex]

answer 7344012

percent *612000 =

(12:100)*612000 =

(12*612000):100 =

7344000:100 = 73440

Now we have: 12 percent of 612000 = 73440

Question: What is 12 percent of 612000?

Percentage solution with steps:

Step 1: Our output value is 612000.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$612000=100\%$.

Step 4: Similarly, $x=12\%$.

Step 5: This results in a pair of simple equations:

$612000=100\%(1)$.

$x=12\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{612000}{x}=\frac{100\%}{12\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{612000}=\frac{12}{100}$

$\Rightarrow x=73440$

Therefore, $12\%$ of $612000$ is $73440$
