Answer:

UNDEFINED

Step-by-step explanation:

change in y over the change in x is how you'd find slope, however, x is the same in both of these, making this a limitation not an equation, therefore the slope is undefined 18-18 = 0 -> Anything divided by zero as a slope is undefined.

38h-24 is the expression represents the perimeter, in centimeters, of the rectangle

The area of Rectangle is length times of width.

The width of a rectangle measures (10h-4) centimeters

Length measures (9h-8) centimeters

The perimeter of rectangle=2(Length+Breadth)

=2(10h-4+9h-8)

Add the like terms in parenthesis

=2(19h-12)

Distribute 2 to the whole parenthesis

=38h-24

Hence, 38h-24 is the expression represents the perimeter, in centimeters, of the rectangle

Answer:

A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because.

Answer:

A. 160 Out of 40 is 400%./// B. The answer is 25/// C.  The answer is 3905%

Step-by-step explanation:

( A )  One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 160 is 40% of =  160 X 100     = 400

                                        40

( B ) The same thing as A but the numbers are switched

       One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 40 is 160% of = 40 × 100      = 25

                                          160

( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:

1602 - 40 = 1562

Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:

1562      = 39.05          

40

We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?

39.05 x 100 = 3905%

160 is percentage of 40,  40 is 160% , number is 40% of 1602​ are 64 , 64 and 640.8 respectively.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Problem A,

40% of 160 = 160 x 40 / 100

                  = 64

Problem B,

160% of 40 = 160 x 40 / 100

                  = 64

Problem C,

40% of 1602 = 1602 x 40 / 100

                     = 640.8

Therefore, 160 is percentage of 40,  40 is 160% , number is 40% of 1602​ are 64 , 64 and 640.8 respectively.

Answer: 1,200 dollars

Step-by-step explanation:

We know that the cost before the discount is 6,000.

The discount price is 80% off.

So, subtract 4,800 by 6,000 because 80% of 6,000 is 4,800.

Now, we have to add the two zeros. We get 1200.

It is the answer to the question.

Answer:

because AC and BD bis => AX = XC; BX = XD

ΔAXD ≅ ΔCXB (SAS) because: AX = CX

                                                    DX = BX

                                                    m∠AXD = m∠BXC ( 2 opposing angles)

because ΔAXD ≅ ΔCXB (SAS)

=> AD = BC and m∠DAX = m∠BCX

because m∠DAX = m∠BCX => AD//BC

ABCD has AD = BC and AD//BC => ABCD is a parallelogram

Answer:

R=50 degrees

Step-by-step explanation:

All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:

180= (3x+5) + (11x-1) + (5x+5)

You then combine like terms:

180= (3x+11x+5x) + (5-1+5)

180= 19x+9

Then, subtract 9 from 180:

171= 19x

Then, divide 171 by 19:

9= x

Finally, you plug the value of x into the equation representing angle R:

5 x 9 + 5

45 + 5

50

Answer:

Step-by-step explanation:

Slope intercept form is found by [ y = mx + b ] where m = slope and b = y-intercept. We are given that a salesperson gets $40000 as a base salary. Since this value doesn't change it is the starting value, in other words the y-intercept. The salesperson also gets $3000 for every subscription they sell. Since this amount grows at a constant rate, that is the slope. Now, we can write the slope intercept form of [ y = 3000x + 40000 ].

Best of Luck!

Answer:

1. y = 3000x + 40000

2. Option A: base salary of the salesperson

3. Option A: the commission per subscription

Step-by-step explanation:

1. The commission of $3000 will be the first number, then will come the salary. Now, since it has to be in slope form, it is on the y-intercept, so we write y.

2. It is the base salary because it is the only number that does not have a missing value, 3000x does.

3. The commission per subscription is the answer because the context of the whole slope is the commission per subscription. Question 2 was the y-intercept.

1-  A.  3(10÷2) +2·7

2- A.  0.4

3- B.  -2.8

4- C.  n·6 - 12 = 60

Step-by-step explanation:

Heres the work in case teachers ask:

1. The given expression evaluates to ...

30÷2 + 2·7 = 15 + 14 = 29

A: 3(10÷2) + 2·7 = 3·5 + 2·7 = 15 + 14 = 29 . . . . . this will make it true

B: 30÷(6+2)·7 = (30/8)·7 = 210/8 = 26 1/4 . . . . . . ≠ 29

C: 3(10)÷(2+2)·7 = 30/4·7 = 210/4 = 52 1/2 . . . . . ≠ 29

D: (5+2)·7 = 7·7 = 49 . . . . . . . . . . . . . . . . . . . . . . . ≠ 29

2. You can divide the equation by 10 to find the appropriate value of x.

4/10 = 10x/10 = x . . . . . 4/10 matches choice A

3. The expression simplifies to ...

7.5 -10.3 = -2.8 . . . . . . matches choice B

4. "The product of a number and 6" is n×6. Twelve less is n×6 - 12. When that "is 60", the equation can be written ...
