Answer:

b. -2/3

Step-by-step explanation:

in addition a negative plus a negative does not equal a positive so we can already assume the answer is b but to be safe we can work this problem out in this way: 1/9 + 5/9 = 6/9 we simplify 6/9 and we get 2/3 so we slap the negative back on and boom -2/3

ikadub [295]

Answer:

29%

Step-by-step explanation:

210-150/210 = 60/210 or 6/21

Now we have to find the percent out of 100 so we have to find out 100/21 to see what we have to multiply by to get to 100 so we can do the same with the 2 (numerator) so 1000/21= 4 16/21

then we have to multiply the 6 by 4 16/21 which is about 29%

The cost price of 18 sweaters is Rs425 per sweater and the total gain of the shopkeeper is Rs 6,750 1 find the sale price of eac
Nostrana [21]

Answer:

1. Sales price per sweater= Rs 800

2. percentage = 46.875% = 46.88%

Step-by-step explanation:

Given;

Cost price = Rs425 per sweater

Number of sweaters = 18

Total gain = Rs 6,750

Total cost price = cost price × number of sweaters

Total cost price = 18 × Rs425 = Rs 7,650

Total sales price = total gain + total cost price

Total sales price = Rs 6,750 + Rs 7,650

Total sales price = Rs 14,400

Sales price (per sweater) = Rs 14,400/18 = Rs 800 per sweater

Profit percentage = total gain/total sales price × 100%

Profit percentage = Rs 6,750/Rs 14,400 × 100%

Profit percentage = 46.875% = 46.88%

What is the equation of this circle in standard form?
creativ13 [48]

Answer:

Option C.

Step-by-step explanation:

Note : In the given points one point is (8,-2) instead of (-6,-2).

The standard form of a circle is

(x-h)^2+(y-k)^2=r^2

where, (h,k) is center of circle and r is radius.

It is given that center of the circle is (-1,-2). So,

h=-1,k=-2

(x-(-1))^2+(y-(-2))^2=r^2

(x+1)^2+(y+2)^2=r^2    ...(1)

It is given that the circle passing through the point (8,-2),(-1,5),(6,-2),(-1,-9).

Substitute x=6 and y=-2 in equation (1).

(6+1)^2+(-2+2)^2=r^2

(7)^2+(0)^2=r^2

49=r^2

Substitute r^2=49 in equation (1).

(x+1)^2+(y+2)^2=49

Therefore, the correct option is C.
