Answer:

$5.50

Step-by-step explanation:

We can list out some values and continue this pattern until we reach 11 pages.

2 pages costs $1

4 pages costs $2

6 pages costs $3

8 pages costs $4

These are all points described by your graph. We will notice that every two pages costs $1, which also means that each additional page costs $0.50

This means that:

10 pages costs $5

and

11 pages costs $5 + $0.50 = $5.50

For part 5 the total value is $1845, for part 6 the total net worth is $3200, and for part 7 the debt to assets value is 0.433.

It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.

Total value = 20×30 + 18×40 + 35×15 = $1845

Net worth = (3500 + 300 + 600) - (1000+200) = $3200

Total debt value = 2000+3200 = $5200

Total assets value = 10000+1300+700 = $12000

Debt to assets value = 5200/12000 = 0.433

Similarly, we can find any debt to assets value by using the formula:

Debt to assets value = Total debt/Total assets

Thus, for part 5 the total value is $1845, for part 6 the total net worth is $3200, and for part 7 the debt to assets value is 0.433.

Hi.Please its urgent See image for question Answer no 16 and 17

Eexplanation:

16. Suppose the roots are α and kα. Then we can write the equation as ...

a(x -α)(x -kα) = 0

ax² -ax(α +kα) +akα² = 0

Comparing to the original equation, we can equate coefficients to get ...

b = -aα(1+k)
c = akα²

Solving the first for α gives ...

α = -b/(a(1+k)

Substituting into the second, we have ...

c = ak(-b/(a(1+k)))²

Multiplying by a(1+k)², we get ...

(1+k)²ac = kb²

Using k=2 gives ...

9ac = 2b² . . . . . as required

17. Using the previous result with k=1 (equal roots), we have ...

(1+k)²ac = kb²

4ac = b² . . . . . for k=1

______

Additional comment

We observed that the problems were similar, but had different factors relating the roots. So, we elected to solve the general case, then fill in the specific values for the two problems.

A department store buys 100 shirts at a cost of $700 and sells them at a selling price of $10 each. Find the percent markup.

Serjik [45]

Answer:

42.8%

Step-by-step explanation:

Step one:

given data

A department store buys 100 shirts at a cost of $700

let us find the cost of 1 shirt

cost of 1 shirt= 700/100= $7 per shirt

The cost price per shirt = $7

We are given that the selling price = $10 per shirt

Step two:

The percent markup can be found as

percent markup= selling-cost price/cost price*100

percent markup= 10-7/10*100

percent markup= 3/7*100

percent markup= 0.428*100

percent markup= 42.8%

PLSSSS HELP SHOW WORK WILL CROWN BRAINLIEST 20pts!!!!!!!!!!!!!!!!!

ankoles [38]

The center is (0,0)
You are looking for a scale factor of 4..

Point a is found at (-3,1)
Point B (4,-3)
Point C (2,3)
Point D (-1,4)

Multiply each value by the scale factor of 4..

x:
Point A = -3 * 4 = -12
Point B = 4*4=16
Point C= 2*4=8
Point D=-1*4=-4

y:
Point A= 1*4=4
Point B= -3*4=-12
Point C= 3*4=12
Point D= 4*4=16

Your dilated points are:

A : (-12,4)
B : (16,-12)
C : (8,12)
D : (-4,16)

Hope this helps!
