What is the coefficient of 5a^2-7

Answer:

$44.90

Step-by-step explanation:

The resulting value for the company of replacing a failed product is given by the price of the warranty minus the cost of replacement:

F = $47-$300=-$253

This event has a 0.7% chance of happening.

The resulting value for selling extended warranty to a product that does not fail is given by the price of the warranty:

W = $47

This event has a 99.3% chance of happening.

The expected value is:

EV = $44 * 0.993 + ($47-$300) *0.007

EV = $44.90

The expected value for each warranty sold is $44.90.

Answer:

It is B

Step-by-step explanation:

Expressions are mathematical statements without the equal sign

The value of 5w^2 - 5w - 8 when x = 3 is 22

The expression is given as:

5w^2 - 5w - 8

When the value of w is 3, the expression becomes

[tex]5w^2 - 5w - 8 = 5*3^2 - 5*3 - 8[/tex]

Evaluate the exponents

[tex]5w^2 - 5w - 8 = 5*9 - 5*3 - 8[/tex]

Evaluate the products

[tex]5w^2 - 5w - 8 = 45- 15 - 8[/tex]

Evaluate the differences

[tex]5w^2 - 5w - 8 = 22[/tex]

Hence, the value of 5w^2 - 5w - 8 when x = 3 is 22

k/9  = 3(9) + 4

k = 31/9

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

8 + b = -5

  -4

8 + b = -5 (-4)

8 +  b = 20

b = 20 - 8

b = 12

k = 31/9

b = 12  

k - 4 = 3

k/9  = 3(9) + 4

k = 31/9

Answer:

Hi there!

Your answer is

(C-12)/A = M

Step-by-step explanation

c=12+a * m

SOLVE FOR M!

C=12+AM

-12

C-12+AM

Divide out A to isolate M

(C-12)/A = M

The equation that can be used to find the number of minutes[m] a customer used is -   m = (c - 12)/a

Equation rearrangement is a process of arranging the equation parameters in terms of a specific parameter.

Given is a phone company that charges a base fee of $12 per month plus an additional charge per minute. The monthly phone charge cost [c] can be represented by the equation: c = 12 + a x m, where [a] is the additional charge per minute, and [m] is the number of minutes used.

The given equation is -

c = 12 + a x m

Since, we know the values of [a] and [c], we can solve for [m] as follows -

c = 12 + a x m

c - 12 = a x m

m = (c - 12)/a

Therefore, the equation that can be used to find the number of minutes[m] a customer used is -

m = (c - 12)/a

Answer: 5/11

Tip:

You can solve for these repeating fractions by putting the repeating digits over 9's!

For example, 0.33 repeating:

33/99 = 1/3

And in the case of your problem:

0.454545...

45/99 = 5/11 (simplify!)

W'X' is the dilated image, which is smaller than the original, so the scale factor would be less than 1.

Set up a ratio of the dilated figure to the original:

15/18 divide this by 3 to get 5/6

The answer is 3) 5/6

Answer:

The slope between (-5,1) and (4,4) is 1/3

Step-by-step explanation:

When you're given 2 points and you must find the slope between those 2 points, you can find the distance between the y values and the x values.

For example in this case, the distance in our first y value is 3. So we know that y is always above x so we have 3/x so far.

Next to find the x values you do the exact same, and we get a distance of 9 from -5 to +4.

Now we have 3/9 which should be simplified to 1/3. When plotting this point, you'll use the strategy Rise over Run or Rise/Run.

(Side Note: Y is always above X so we know the Rise must be Y and the X must be Run.)

Y/X = Rise/Run

Answer:

1320, permutation

Step-by-step explanation:

There are 12 members

Pick a president

We have 12 choices

Now there are 11 people left to pick from

now pick a vp

We have 11 choices

Now there are 10 people left to pick from

now pick a secretary

We have 10 choices

12*11*10 = 1320

This is a permutation since it matters who is president, vp and secretary

Step-by-step explanation:

5x - 4 > 12 adding 4 to both sides;

5x - 4 + 4 > 12 + 4

5x > 16 dividing both sides by 5;

x > 16/5

12x + 5-4

12x + 1

Step-by-step explanation:

When you have a negative next to a negative, you can turn it into a positive. For example the -(-8) would now be +8. This is called the airplane strategy because it forms a airplane if you flip you sheet of paper or your device.

From here, we have -3+8.

Now we subtract since each value has a different sign and we get +5.

Step-by-step explanation:

Answer:

1. 21+5f = 61

2. 18+5n=50.50

3. 40+30s=220

Step-by-step explanation:

1. SUM of 21 and 5 TIMES a number f is 61

From that sentence, sum means addition and times is multiplication, so:

21+5f = 61

2. Let's identify the given:

Monthly fee: 18

Cost of each call: 5

Variable that symbolizes the call: n

Total cost this month: 50.50

Thus, 18+5n=50.50

3. Identify the given:

Charge of tutor: 40

Charge of tutor every student: 30

Variable representing the number of students: s

Total charge: 220

Thus, 40+30s=220

In triangle ABC:

∠1 = 90°

According to the angle sum property:

∠1 + ∠2 + ∠3 = 180

Since angle 1 is 90 degrees

∠2 + ∠3 = 180 - 90

∠2 + ∠3 = 90°    [∠1 + ∠2 + ∠3 = 180]
