Step-by-step explanation:

Cost price (CP) = Purchase amount + amount spend on repairing

= 85000 + 5000

= ₹ 90000

Profit % = 10%

$SP = \frac{100+Profit}{100}*CP\\\\=\frac{100+10}{100}*90000\\\\ = \frac{110}{100}*90000$

Which set of ordered pairs is a partial solution set for the system y<0 and x≤y?

jeka57 [31]

Answer:

{(−1,−1),(−7,−6),(−8,−2),(−10,−3)}

Step-by-step explanation:

we are given

y<0 and x≤y

so, we can write as

$x\leq y$

so, both values must be less than 0 or negative

we will verify each options

option-A:

Since, $x\leq y$

So, all solution satisfies

so, this is TRUE

option-B:

Since, $x\leq y$

x=-6 and y=-7

-7<-6

so, y<x

So, it does not satisfy solution

so, this is FALSE

option-C:

Since, solutions will be in points

intersection means interval

so, this is not valid solution

so, this is FALSE

option-D:

Since, $x\leq y$

So, all solution satisfies

so, this is TRUE

in a piggy bank, 40% of the coins are dimes and three-eighths of the remainder are nickels. A coin is randomly drawn from the ba

Vera_Pavlovna [14]

In a piggy bank, 40% of the coins are dimes.
3/8 of the remainder are nickels.
The remainder is going to be 60%
1/8 of 60% is 7.5%. (just dividing by 8)
3/8 of 60% = 7.5% × 3 = 22.5% are nickels.
If 22.5% are nickels, then 77.5% are not.
The percentage of coins that aren't nickels is the same as the probability of drawing one because each coin has equal probability to be chosen.

Paula kitten weighs 3 1/2 pounds write this weight in the boxes using pounds and ounces.

Elenna [48]

Answer:

Step by step explanation

First, we have to convert 3 1/2 into a decimal, so we have to do the following:

1/2 = 1 divided by 2 3 1/2 = 3 + (1÷2) = 0.5 (1 ÷ 2 done by long division)

Then we add the whole number.

3 + 0.5 = 3.5

Next, we multiply

3.5 x 16 = 56 ounces.
