Answer:

2v + 1d = 105

and

1v + 4d = 80

Step-by-step explanation:

ken : 2v + 1d = 105

Jerome : 1v + 4d = 80

1v + 4d = 80 Try to get a video games by its self

   - 4d    -4d

1v = 80 - 4d    

Plug into kens equation..

2(80 -4d) + 1d = 105

160 - 8d + 1d = 105

-160                 -160

-7d = -55

/-7        /-7

d = 7.86 (rounded)

Plug into Jeromes equation

1(7.86) + 4v = 80

- 7.86            - 7.86

4v = 72.14

/4     /4

v = 18.035 (round = 18)

Answer: See explanation

Step-by-step explanation:

Sita bought a sofa set for Rs 30,000 and sold the sofa set at a loss of 5%. The loss on the sofa will be:

= 5% × 30000

= 5/100 × 30000

= 0.05 × 30000

= 1500

Selling price of the sofa = 30000 - 1500 = 28500

Sita bought a dining set for Rs 20,000 and made a profit of 5% on the dining set. The selling price of the dining set will be:

= 20000 + (5% × 20000)

= 20000 + (0.05 × 20000)

= 20000 + 1000

= 21000

The cost price of the sofa and dining set will be:

= Rs 20000 + Rs 30000

= Rs 50000

The selling price of the dining set will be:

= Rs 28500 + Rs 21000

= Rs 49500

The net result of the transaction is will be:

Selling price - Cost price

= 49500 - 50000

= -500

There's a net loss of $500

Sentence:

SHE WASN'T SEEN BECAUSE OF HER SMALL SIZE.

Answer:

7300    

  Step-by-step explanation:

I got it right  

Melanie would need to invest an amount of $7300.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

The final amount in a compound interest can be calculated using the formula,

A = P (1 + [tex]\frac{r}{n}[/tex] )^(n t)

Here A is the final amount, P is the principal value, r is the rate of interest, n is the number of times interest is compounded per year and t is the number of years.

Given,

A = $19,600

r = 5.2% = 5.2/100 = 0.052

Since it is compounded monthly, n = 12

t = 19 years

Substituting,

19,600 = P (1 + [tex]\frac{0.052}{12}[/tex])^ (12 × 19)

19,600 = P (1.0043)^(228)

19,600 = P (2.68)

P = 19,600 / 2.68

P = 7313.0767 ≈ 7300 to the nearest hundred

Hence the value of the account will reach $19,600 n 19 years if she invest an amount of $7300.

Step-by-step explanation:

Answer:

The area is 2,600 cm^2

Step-by-step explanation:

The area of a rectangle is the product of its sides

And the difference between both areas is 1,400 cm^2 (P-Q)

Thus, we have it that;

40(3x-10) - (30(x + 15)) = 1,400

120x - 400 - 30x - 450 = 1400

120x -30x -400-450 = 1400

90x - 850 = 1400

90x = 1400 + 850

90x = 2,250

x = 2,250/90

x = 25

The area for painting P

is;

40 (3x - 10)

Substituting the value 25 for x

we have

40 ( 3(25) -10)

= 40(75-10)

40 * 65 = 2,600 cm^2

Answer:

52.36

Step-by-step explanation:

Formula to find volume in a cone is

V = pi • radius^2 h/3

So we fill in the numbers

V = pi •

the radius is half of diameter,

The diameter is 5

So it's

V = pi • 2.5

since it's half of 5

V = pi • 2.5^2 h/3

the height is 8 so we fill it in

V = pi • 2.5^2 8/3

When calculated, you get..

52.36

The volume of the liquid which can fill the bowl of the glass (in shape of cone) with the liquid is 49.74 cm³.

Volume of solid is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.

The volume of the cone can be given as,

[tex]V=\dfrac{1}{3}\pi r^2\sqrt{l^2-r^2}[/tex]

Here, (r) is the radius of the base of the cone and (l) is the slant height of the cone.

Here, the diameter of the cone is 5 cm. thus the radius of the cone is,

[tex]r=\dfrac{5}{2}\\r=2.5\rm cm[/tex]

The slant height of the cone is 8 cm. Thus, put the value to find the volume of cone as,

[tex]V=\dfrac{1}{3}\pi (2.5)^2\sqrt{(8)^2-(2.5)^2}\\V\cong 49.74\rm cm^3[/tex]

Thus the volume of the liquid which can fill the bowl of the glass (in shape of cone) with the liquid is 49.74 cm³.
